Abstract
Description
- 1. Field of the Invention
- The present invention relates to an all terrain vehicle, especially to an all terrain vehicle including a radiator is disposed in a front section of a vehicle body.
- 2. Description of the Related Art
- US Patent Publication No. 2004/0206567 A1 discloses an example of the conventional all terrain vehicles. The vehicle is provided with a cabin, functioning as a space for carrying a driver and a passenger. The cabin is disposed between front wheels and rear wheels in a longitudinal direction of the vehicle. Additionally, a front frame is disposed forward of the cabin. The front frame defines a portion of a vehicle body frame. A variety of components, including e.g., a front gear case, a pair of front suspensions and a radiator, are supported by the front frame. To reliably achieve engine cooling, the radiator is disposed forward of the front frame while disposed rearward of a vehicle body cover.
- Requests have been made for compactly forming the entire vehicle of this type. As described above, however, the radiator is disposed forward of the front frame. The vehicle is accordingly required to have components for attaching the radiator to the vehicle and a space for blocking contact with and attachment of soil and water (e.g., mud) to the radiator. Finally, the entire vehicle size inevitably becomes large even if the front frame of a minimum required size is planned.
- Moreover, according to the vehicle disclosed in the aforementioned patent publication, a driver operates a steering mechanism while seated. To achieve better operability and riding comfort for the driver, a considerable space is necessary between a seat and a front panel provided with the steering mechanism.
- According to the conventional vehicle, the front section of the vehicle is particularly formed to have a large size. To compactly form the vehicle, the structure of the front section disposed forward of the cabin in particular should be carefully devised. Specifically, structures and arrangements of the front frame and a variety of components supported thereby (e.g., the front suspensions, the front gear case and the radiator) should be appropriately designed.
- In view of the above, preferred embodiments of the present invention provide a vehicle having a compact front section even though a variety of components are functionally disposed in the front section.
- An all terrain vehicle according to a preferred embodiment of the present invention includes a pair of right and left front wheels, at least a pair of right and left rear wheels, a vehicle body frame, a pair of right and left first roof supports, a pair of right and left second roof supports, a pair of right and left roof members, a seat, a front panel, a front gear case, a pair of front suspensions, a vehicle body cover, a radiator and a pair of right and left headlight units. The vehicle body frame supports the front wheels and the rear wheels. The vehicle body frame includes a pair of right and left upper frames, a pair of right and left lower frames, and a pair of right and left front frames. The upper frames extend in a longitudinal direction of the vehicle. The upper frames are disposed above the front wheels in a substantially vertical direction of the vehicle. The lower frames extend in the longitudinal direction of the vehicle. The lower frames are disposed below and opposed to the right and left upper frames in the substantially vertical direction of the vehicle, respectively. The front frames extend in the substantially vertical direction of the vehicle. The right front frame connects a front portion of the right upper frame and a front portion of the right lower frame, whereas the left front frame connects a front portion of the left upper frame and a front portion of the left lower frame. The first roof supports are provided at lateral sides of the vehicle body frame in a transverse direction of the vehicle, respectively. Each of the first roof supports includes a pipe member extending in the substantially vertical direction of the vehicle. The second roof supports are provided at lateral sides of the vehicle body frame in the transverse direction of the vehicle, respectively. The second roof supports are disposed rearward of the first roof supports in the longitudinal direction of the vehicle. Each of the second roof supports includes a pipe member extending in the substantially vertical direction of the vehicle. The right roof member connects an upper portion of the right first roof support and an upper portion of the right second roof support, whereas the left roof member connects an upper portion of the left first roof support and an upper portion of the left second roof support. The seat includes a seating surface disposed forward of the rear end of the second roof support in a transverse side view of the vehicle. The front panel sections a cabin and a front space of a front section of the vehicle. The cabin includes the seat therein. The front space is positioned longitudinally forward of the cabin. The front gear case is supported by the right and left lower frames. The right and left front suspensions include a pair of right and left shock absorbers, respectively. Upper ends of the shock absorbers are coupled to the pair of right and left upper frames, respectively, whereas lower ends of the shock absorbers are coupled to the pair of right and left front wheels. The vehicle body cover covers front of the front frames in the longitudinal direction of the vehicle. The radiator is disposed longitudinally rearward of the front frames in the transverse side view of the vehicle while disposed longitudinally forward of the shock absorbers in the transverse side view of the vehicle. The radiator is disposed in a position including a transverse center of the vehicle. The head light units are positioned above the radiator in the transverse side view of the vehicle. The head light units longitudinally overlap with the radiator.
- According to a preferred embodiment of the present invention, the radiator is disposed in a space provided between the front end of the vehicle body frame and the shock absorbers. Additionally, the radiator and the head light units overlap in the substantially vertical direction. With the structure, the entire vehicle has a very compact configuration.
- Additionally, the vehicle body cover is attached to the front end of the vehicle body frame. In other words, the frame exists between the vehicle body cover and the radiator. The radiator is thus disposed away from the vehicle body cover. With this unique structure, it is possible to inhibit contact with and attachment of soil and water (e.g., mud) to the radiator. Moreover, the radiator does not overlap with the suspensions. With the structure, the radiator is allowed to be enlarged in the transverse direction of the vehicle. This achieves enhancement of cooling performance of the radiator.

The first roof supports 7 and the second roof supports 8 are provided at transversely lateral sides of a longitudinally center portion of the vehicle body frame 4, respectively. Furthermore, the all terrain vehicle includes acabin 11, afront space 12 and arear space 14. Thecabin 11 accommodates theseats 10. Thecabin 11 thus functions as a space for carrying a driver and/or a passenger. Thefront space 12 is a front section of the vehicle disposed forward of thecabin 11. Therear space 14 is a rear section of the vehicle that acargo 13 is disposed thereon. Additionally, afront panel 15 is provided between thecabin 11 and thefront space 12. Thecabin 11 and thefront space 12 are thus sectioned by thefront panel 15. - The vehicle body frame 4 mainly includes a
center frame unit 20, afront frame unit 21 and arear frame unit 22. Thecenter frame unit 20 defines a bottom portion of thecabin 11. Thefront frame unit 21 is disposed in thefront space 12 positioned forward of thecenter frame unit 20. Thefront frame unit 21 thus defines a front section of the vehicle. Additionally, therear frame unit 22 is disposed in arear space 14 positioned rearward of thecenter frame unit 20. Therear frame unit 22 thus defines a rear section of the vehicle. - The
center frame unit 20 includes a plurality of pipe members. Thecenter frame unit 20 supports theengine unit 5 through engine brackets (not illustrated in the figure). - Similarly to the
center frame unit 20, each of thefront frame unit 21 and therear frame unit 22 includes a plurality of pipe members. Therear frame unit 22 supports a variety of components, including e.g., anexhaust duct 23 and a pair of right and leftrear suspensions 24.

A coolingduct 32 is connected to theCVT 29 for mainly cooling a belt. The coolingduct 32 is disposed rearward of thefront space 12. In other words, the coolingduct 32 is disposed in the portion positioned forward of thecabin 11. - The
power transmission mechanism 6 includes afront drive shaft 34, arear drive shaft 35, afront gear case 36 and arear gear case 37. Thefront drive shaft 34 and therear drive shaft 35 are connected to the output side of theCVT 29. Thefront gear case 36 is disposed among the tip of thefront drive shaft 34 and thefront wheels 2 whereas therear gear case 37 is disposed among the tip of therear drive shaft 35 and therear wheels 3. - The pair of right and left first roof supports 7, the pair of right and left second roof supports 8 and the pair of right and left
roof members 9 define a pair of right and left lateral frames of thecabin 11. - The first roof supports 7 define the front ends of the pair of right and left lateral sides of the
cabin 11. Each of the first roof supports 7 includes a pipe member extending in the substantially vertical direction. Each of the first roof supports 7 is divided into alower support 7 a and anupper support 7 b. Thelower support 7 a and theupper support 7 b are coupled preferably by a single or plurality of bolts, for example. Thelower support 7 a slants forward from its lower end to its upper end (i.e., a coupling portion with theupper support 7 b). On the other hand, theupper support 7 b slants rearward from its lower end (i.e., a coupling portion with thelower support 7 a) to its upper end. - The second roof supports 8 define the rear ends of the pair of right and left lateral sides of the
cabin 11. Each of the second roof supports 8 includes a pipe member extending in the substantially vertical direction. Similarly to the first roof supports 7, each of the second roof supports 8 is divided into alower support 8 a and anupper support 8 b. Thelower support 8 a and theupper support 8 b are coupled preferably by a single or plurality of bolts, for example. Thelower support 8 a slants rearward from its lower end to its upper end (i.e., a coupling portion with theupper support 8 b). On the other hand, theupper support 8 b is disposed approximately-upright. - Note each of the first and second roof supports 7 and 8 is divided into lower and upper supports at its approximately vertical center portion. The coupling portions between the lower and upper supports are positioned at approximately the same height as the upper end of the
front panel 15. - Each of the
roof members 9 includes a pipe member extending in the longitudinal direction. The right/left roof member 9 is provided between the upper end of the right/left first roof support 7 and the upper end of the right/leftsecond roof support 8. Theroof members 9 are approximately horizontally disposed. Furthermore, twocoupling members 39 are disposed between the pair of right and leftroof members 9. Theroof members 9 are coupled by thecoupling members 39. - The right and left lateral frames of the
cabin 11 further include a pair of right and leftlower members 40 in addition to the first roof supports 7, the second roof supports 8 and theroof members 9. Each of thelower members 40 includes a pipe member. The right/leftlower member 40 is disposed between the lower end of the right/left first roof support 7 and the lower end of the right/leftsecond roof support 8. Thelower members 40 are approximately horizontally disposed. Thelower members 40 are thus opposed to theroof members 9 in the substantially vertical direction. - In the present preferred embodiment, the right/left
upper support 7 b of the right/left first roof support 7, the right/leftupper support 8 b of the right/leftsecond roof support 8 and the right/left roof member 9 are preferably formed by bending a piece of pipe member, for example. Similarly, the right/leftlower support 7 a of the right/left first roof support 7, the right/leftlower support 8 a of the right/leftsecond roof support 8 and the right/leftlower member 40 are preferably formed by bending a piece of member, for example. - As seen in
FIGS. 1A , 2 and 4, thecabin 11 is provided with thefront panel 15, abottom floor panel 42 and acenter console 43. Thecenter console 43 is disposed between the right and leftseats 10. Thecabin 11 is defined as a space enclosed by thefloor panel 42, thefront panel 15, and a portion of the pair of right and left lateral frames (including the first and second roof supports 7 and 8 and the roof members 9) disposed above thefront panel 15. - A
steering mechanism 44 is disposed in front of theleft seat 10 within thecabin 11. Theseats 10 are disposed forward of the rear ends of the second roof supports 8 within thecabin 11. More specifically, each of the right and leftseats 10 includes aseating surface 10 a and aback support 10 b. Theback support 10 b supports the back of a driver/passenger. The back supports 10 b of theseats 10 may overlap with the second roof supports 8 in the longitudinal direction. Alternatively, the back supports 10 b may be partially positioned rearward of the second roof supports 8. However, the seating surfaces 10 a of theseats 10 are always positioned forward of the rear ends of the second roof supports 8. - Furthermore, the
center console 43 is disposed rearward of thefront panel 15 while disposed in approximately the center portion of the vehicle in the transverse direction. Thecenter console 43 extends rearward of theseats 10. Thecenter console 43 includes left, right and upper walls. Thecenter console 43 is formed in an inverse U-shape, and thereby includes an inner space. As illustrated inFIG. 1A , a speedchange control lever 45 and a sidebrake control lever 46 are disposed in the front portion of thecenter console 43 whereas a bottle receiver 47 (seeFIGS. 2 and 4) is disposed on the rear portion of thecenter console 43 for receiving a single or plurality of beverage bottles. - As described above, the
front panel 15 is a member for sectioning thecabin 11 and thefront space 12 positioned forward of thecabin 11. As illustrated inFIG. 4 , thefront panel 15 includes avertical panel 15 a and adashboard 50. Thevertical panel 15 a extends continuously upward from thefloor panel 42 of thecabin 11. Thedashboard 50 is disposed on the upper end of thevertical panel 15 a. As illustrated inFIG. 5 , thesteering mechanism 44 is attached to the left portion of thedashboard 50 whereas ameter unit 51, including a display (e.g., a speedometer), is disposed in the transversely center portion of thedashboard 50. Electric components are installed in the interior of themeter unit 51. - Next, structure of the front section of the vehicle, that is, structure of the
front space 12 positioned forward of thefront panel 15, will be hereinafter explained in detail. - As described above, the
front frame unit 21 is disposed in thefront space 12. As illustrated inFIGS. 1A to 3 and 6, thefront frame unit 21 supports thefront gear case 36, a pair of right and leftfront suspensions 54, afront box 55, afront cover 56, afront carry bar 57, a pair of right and leftfront fenders 58 and aradiator 59. Additionally, ahood 60 is disposed between thefront fenders 58. Moreover, right and lefthead light units 64 and afront grill 65 are attached to thefront cover 56. - As illustrated in
FIG. 3 , thefront frame unit 21 is transversely symmetrically formed. The right-half/left-half portion of thefront frame unit 21 includes a right/leftupper frame 68, a right/leftvertical frame 69 and a right/leftlower frame 70. The right and leftupper frames 68 are coupled to the upper front end of thecenter frame unit 20, and extend forward therefrom. The right/leftvertical frame 69 is formed in a bent shape, and extends downward from the front end of the right/leftupper frame 68. The right and leftlower frames 70 are coupled to the lower front end of thecenter frame unit 20, and extend forward therefrom. The front end of the right/leftlower frame 70 is connected to the lower end of the right/leftvertical frame 69. Note theframe elements front frame unit 21. - The
front gear case 36 is supported by the right and left lower frames 70. Additionally, thefront gear case 36 is coupled to a pair of right andleft hubs 2 a of the right and leftfront wheels 2 by a pair of right and left shafts (seeFIGS. 1A , 1B and 2). - Each of the right and left
front suspensions 54 includes ashock absorber 72 and an arm member. The right and leftshock absorbers 72 are arranged in an inverse V-shape in a front view of the vehicle. The lower end of the right/leftshock absorber 72 is coupled to the right/left hub 2 a of the right/left front wheel 2 through e.g., a knuckle arm whereas the upper end of the right/leftshock absorber 72 is supported by the front portion of the right/leftupper frame 68. - As illustrated in detail in
FIGS. 6 and 7 , thefront cover 56 includes acenter portion 74 and a pair of right and left head light covers 75. Thecenter portion 74 is provided in approximately the center of thefront cover 56 in the transverse direction, and includes an opening. Thecenter portion 74 and the head light covers 75 preferably are integrally formed. Thecenter portion 74 is disposed forward of theradiator 59 for covering it. The lower end of thecenter portion 74 extends further downward than the lower end of theradiator 59. - The
front grill 65 covers the front of thecenter portion 74 of thefront cover 56. - As illustrated in
FIG. 9 , each of the right and lefthead light units 64 includes a variety of components (e.g., a bulb, a reflection mirror and a lens) in its interior. The right/lefthead light cover 75 of thefront cover 56 covers the surrounding of the right/lefthead light unit 64. Furthermore, a pair of right and leftcaps 76 are provided rearward of thehead light units 64. The right/left cap 76 covers the back of the right/lefthead light cover 75. - The right/left
head light unit 64 is attached to the right/lefthead light cover 75 preferably by a plurality of screws (not illustrated in the figure), for example. A positional relationship between the right/lefthead light unit 64 and the right/lefthead light cover 75 will be hereinafter explained. - As illustrated in detail in
FIGS. 1A , 1B and 2, thefront carry bar 57 includes a plurality of members (e.g.,pipe members 80 and 83). Thefront carry bar 57 is fixed to the front end of thefront frame unit 21. Additionally, thefront carry bar 57 is disposed further forward than thefront cover 56 and thefront grill 65. Right and left resin covers 84 are attached to the transversely lateral ends of thefront carry bar 57, respectively. - L-shaped
members 80 extend in the substantially vertical direction. The upper coupling member 81 couples upper portions of the right and left L-shapedmembers 80 whereas the lower coupling member 82 couples lower portions of the right and left L-shapedmembers 80. The lower end of the right/left L-shapedmember 80 is coupled to the right/leftlower frame 70 of thefront frame unit 21. Furthermore, the right/leftlateral coupling member 83 couples the upper portion of the right/left L-shapedmember 80 and the right/leftvertical frame 69 of thefront frame unit 21. Note each of the members of the frame preferably is a pipe member. - The right and left
front fender 58 cover above the right and leftfront wheels 2, respectively. As illustrated inFIG. 6 , anextension 58 a is formed in the front portion of eachfront fender 58. Theextensions 58 a extend toward the transverse center of the vehicle. As illustrated inFIG. 8 , the right/left extension 58 a covers above the right/lefthead light cover 75. The front end of the right/left extension 58 a extends forward of the front end of the upper portion of the right/lefthead light cover 75. The front end of the right/left extension 58 a reaches approximately the same position as the front end of the lower portion of the right/lefthead light cover 75. - As illustrated in
FIGS. 1A , 1B and 7, theradiator 59 is disposed rearward of thevertical frames 69 of thefront frame unit 21 while being disposed forward of theshock absorbers 72 of thefront suspensions 54. Additionally, an opening of the coolingduct 32, thefront box 55 and electric components (e.g., the battery 85) are disposed between theradiator 59 and thedashboard 50 of thefront panel 15. Moreover, theradiator 59 is disposed in a transverse center of the vehicle. In other words, theradiator 59 is disposed rearward of thecenter portion 74 of thefront cover 56 as described above. Theradiator 59 overlaps with thevertical frames 69 in a front view of the vehicle. The transverse lateral ends of theradiator 59 extends further transversely outward than theframes FIGS. 7 and 10 (i.e., a perspective view of the front section of the vehicle, sectioned along Line X-X ofFIG. 1B ), theradiator 59 is disposed below theupper frames 68 and theupper frames 68 are positioned at approximately the same height as abottom surface 55 a of thefront box 55. In other words, theradiator 59 is disposed below thefront box 55. As is seen inFIG. 1B , theradiator 59 and thehead light units 64 substantially vertically overlap with each other in a side view of the vehicle. - The
hood 60 is disposed between thefront fenders 58 for covering an area above thefront box 55. Thehood 60 is fixed to thefront fenders 58. As is seen in a front view of the vehicle illustrated inFIG. 11 , a thick dashed line indicates that the upper surface of thehood 60 is positioned lower than the front surfaces of the right and leftfront fenders 58. In other words, the upper surfaces of the right and left front fenders 58 (i.e., right and left lateral sides of the vehicle) are positioned higher than the upper surface of thehood 60 interposed therebetween. More specifically, transversely lateral portions of thehood 60 are positioned higher than a transversely center portion thereof. Additionally, the right and leftfront fenders 58 continue to the transversely right and left ends of thehood 60. A transversely outer portion of the right/left front fender 58 is basically positioned higher than a transversely inner portion thereof. Once reaching the highest position, however, the right/left front fender 58 slants downward at an acute angle in the front view of the vehicle. - Thus, the transversely center portion of the vehicle is positioned lower than the transversely lateral portions of the vehicle. With this unique structure, it is possible to further prevent soil and water (e.g., mud) from flying toward a driver and/or a passenger from the transverse directions while wide forward visibility is achieved for a driver and/or a passenger.
- The
front grill 65 is a member extending in the substantially vertical direction. Thefront grill 65 is attached to the front surface of thecenter portion 74 of thefront cover 56. In other words, thefront grill 65 is disposed rearward of thefront carry bar 57. Thefront grill 65 and thecenter portion 74 of thefront cover 56 block intrusion of soil and water (e.g., mud) into the interior of the vehicle from the front direction of the vehicle. - Regarding the aforementioned structure, positional relationships among members of the front section of the vehicle will be hereinafter collectively described.
- The
radiator 59 is preferably disposed in the space between thevertical frames 69 of thefront frame unit 21 and theshock absorbers 72 of thefront suspensions 54. The space, which is provided in the front section of the vehicle, is thus efficiently used for disposing theradiator 59. With the structure, it is possible to compactly form the front section of the vehicle. - Additionally, the
radiator 59 is preferably disposed forward of theshock absorbers 72. It is thereby possible to reliably keep a space positioned rearward of theradiator 59 and forward of thedashboard 50. The space is usable for accommodating thefront box 55, the opening of the coolingduct 32, electric components (e.g., the battery 85). - In a side view of the vehicle, the
radiator 59 and thehead light units 64 substantially vertically overlap in the front section of the vehicle. With the structure, it is possible to further compactly form the front section of the vehicle. - The
front cover 56 is attached to the front end of thefront frame unit 21. Thevertical frames 69 of thefront frame unit 21 are disposed between thefront cover 56 and theradiator 59. In other words, theradiator 59 is disposed rearwardly away from thefront cover 56. With the structure, soil and water (e.g., mud) do not easily contact with or attach to theradiator 59 even if entering behind thefront cover 56. - The
radiator 59 is preferably disposed forward of theshock absorbers 72 of thefront suspensions 54. In other words, theradiator 59 does not overlap with thefront suspensions 54 in the longitudinal direction. With this unique structure, theradiator 59 can be significantly enlarged in the transverse direction of the vehicle. Accordingly, theradiator 59 is capable of reliably providing a large cooling capacity. - The aforementioned preferred embodiment exemplifies that each roof support preferably includes separately divided upper and lower supports. However, it is possible to apply the present invention to a type of vehicle provided with roof supports composed of only the upper supports described in the aforementioned preferred embodiment.
- Specific structures of the vehicle body frame and the vehicle body cover are not particularly limited to the aforementioned preferred embodiment. For example, the front cover may be composed of separately formed members, that is, the head light covers and the center portion.
- Disposition of the radiator is not particularly limited to the aforementioned preferred embodiment. For example, the radiator may be arbitrarily disposed as long as it includes the transverse center of the vehicle. In this case, the radiator may not be transversely symmetrically disposed with respect to the transverse center of the vehicle.
- In the aforementioned preferred embodiment, the present invention is preferably applied to a two-seat vehicle. However, it is similarly possible to apply the present invention to a type of vehicle provided with a rear seat(s) in addition to the front seats.
- While preferred embodiments of the present invention have been described above, it is to be understood that variations and modifications will be apparent to those skilled in the art without departing the scope and spirit of the present invention. The scope of the present invention, therefore, is to be determined solely by the following claims.
