Abstract
An assembly method including a sprocket hub and a locking collar for go kart vehicles and other land vehicles with drive axles is provided to enhance acceleration. The present invention eliminates the need for two locking collars on either side of the sprocket hub. The invention further provides a lightweight sprocket hub with a hub neck portion adapted to receive a single locking collar. The sprocket hub fits loosely on the drive axle. The fin-like sprocket hub arms and sprocket hub extensions each have sprocket connection holes used to connect the sprocket hub to a drive sprocket. The locking collar engages the sprocket hub neck portion by means of two flanges located on the sprocket hub. As assembled, the sprocket hub and locking collar float and oscillate on the drive axle to compensate for chassis flex and chain bind.
Description
- This application is a continuation of application Ser. No. 11/169,544, filed Jun. 29, 2005, which claims priority to provisional application No. 60/584,177, filed on Jun. 30, 2004.
- The present invention relates generally to a collar and sprocket hub apparatus and particularly relates to a single locking collar and sprocket hub apparatus and method for use on the driving axles of land vehicles. The invention can be used on a variety of vehicles, but is designed specifically for use on go kart vehicles or the like.
- The object of the present invention is to provide a sprocket hub and locking collar which is lighter than the prior art sprocket hubs and collar assemblies.
- Another object of the present invention is to provide a sprocket hub and locking collar that is more durable and stronger than conventional sprocket hubs with locking collars.
- Yet another object of the present invention is to provide a sprocket hub and locking collar having a float and oscillating design to compensate for chassis flex and chain bind.
- Yet another object of the present invention is to provide for the need of only one locking collar to further reduce the rotating weight as compared to the prior art two-collar systems.
- Yet another object of the present invention is to provide a sprocket hub that has an increased life through the float and oscillating design.
- Yet another object of the present invention is to provide a sprocket hub that increases the wear of the drive chain and the gear sprocket through the float and oscillating design.
- Yet another object of the present invention is to provide a lightweight sprocket hub that can attach to a gear sprocket.
- Accordingly, what is provided is a sprocket hub having a hub front face, a hub rear face and a plurality of fin-like hub arms. The fin-like hub arms are attached to the outer perimeter of a neck portion which extends in a direction perpendicular to a longitudinal axis of an inner perimeter of the neck portion, wherein the fin-like hub arms have recesses defined therein. A hub arm extension is attached to each of the fin-like hub arms, wherein each of the hub arm extensions has a small recess defined therein. A circular neck portion extends outwardly from the hub front face. The circular hub neck portion includes a neck top flange and a neck bottom flange both located on the end of the neck portion distal to the hub front face. These two flanges are used for attachment to the locking collar. The locking collar has an outer, middle and inner perimeter, and houses a compression screw hole 36 and compression screw 36 a for fastening the collar to a bar adapted to situate in a groove on the driving axle, thus locking the collar onto the axle and sprocket hub. Particularly, a flange groove is defined between the middle perimeter lips and the intermediate surface of the locking collar. This flange groove is spaced such that the neck top flange and the neck bottom flange can fit within the flange groove during attachment of the locking collar to the sprocket hub.
- Also provided is a method of situating a sprocket on a drive axle comprising the steps of sliding a sprocket hub having a bar slot over a drive axle and sliding a locking collar over the drive axle. The locking collar is attached to the drive axle. Next, the sprocket hub is loosely secured to the drive axle and a gear sprocket is attached to the sprocket hub. The next step involves attaching a drive chain to the gear sprocket and allowing the sprocket hub and the locking collar to float and oscillate on the drive axle to compensate for chassis flex and chain bind. The acceleration of the go kart vehicle is enhanced as a result of this configuration. The configuration also increases the life of the sprocket hub, gear sprocket and drive chain.

As is customary, it will be understood that no limitation of the scope of the invention is thereby intended. The invention encompasses such alterations and further modifications in the illustrated apparatus and method, and such further applications of the principles of the invention illustrated herein, as would normally occur to persons skilled in the art to which the invention relates.
- The present invention can be described generally as a
sprocket hub 10 and alocking collar 30 each with an axle opening (21 and 53 respectively) for accepting the drivingaxle 90 of a go kart vehicle or other land vehicle. Thesprocket hub 10 further has abar slot 25 defined on the outer perimeter of the axle opening 21. Thedriving axle 90 includes anaxle groove 91 defined therein (seeFIGS. 8-12 ). Within theaxle groove 91, anaxle groove bar 92 is capable of being placed, such that thebar 92 fits into thebar slot 25 causing thesprocket hub 10 to rotate in unison with thedriving axle 90. Thebar 92 fits loosely into thebar slot 25 to enable the float and oscillating device of the present invention. Thebar slot 25 can be seen inFIGS. 1, 2 , 10 and 11. - As illustrated then with reference to
FIGS. 1-12 ,FIG. 1 shows a front view of thesprocket hub 10 of the present invention. Thesprocket hub 10 has three large fin-like hub arms 14 and three smaller, generally triangularhub arm extensions 14. Thehub arm extensions 14 are attached to the fin-like hub arms 14. The fin-like hub arms 14 have recesses defined therein to reduce the overall weight of thesprocket hub 10. Also, thehub arm extensions 14 have small recesses defined therein to reduce the overall weight of thesprocket hub 10. A recess within the scope of this invention is defined herein as a hole or completely hollowed-out portion and not merely an indentation. - Each of these fin-
like hub arms 14 andhub arm extensions 14 includesprocket connection holes 12 defined therethrough located proximate to the end of the fin-like hub arms 14 andhub arm extensions 14 opposite from theaxle opening 21. The gearsprocket connection holes 12 are used to attach a gear sprocket to thesprocket hub 10 using a bolt, stud or the like. The sprocket is then connected to a drive chain. - The
hub arms 14 can be of any geometry as long as thesprocket connection holes 12 generally form the perimeter of a circle, wherein each is a uniform distance away from the outer perimeter of the axle opening 21. Thehub arms 14 optionally can be replaced with a circular disk or other geometrical figure as long as thesprocket hub 10 includessprocket connection holes 12 defined therethrough, which form generally a perimeter of a circle-like shape and each is a uniform distance away from the outer perimeter of the axle opening 21. - An
optional screw hole 22 is defined through thesprocket hub 10 and is positioned proximate to thebar slot 25 in a direction opposite from the axle opening 21. Thescrew hole 22 provides a means whereby a stabilizing screw can be inserted through the hubrear face 23, travel through the width of thesprocket hub 10, and connect to thecollar bore 34 of thelocking collar 30. This optional stabilizing screw provides greater stability to thesprocket hub 10, the lockingcollar 30 and the assembly as a whole. If the optional stabilizing screw is included the invention will not provide as much float and oscillation to compensate for chassis flex and chain bind. - The
sprocket hub 10 includes ahub neck portion 16 which extends outwardly from thehub front face 24 in a direction opposite from the hubrear face 23. Thehub neck portion 16 is generally radial and has an outer perimeter and an inner perimeter as shown inFIGS. 1, 10 and 11. Thebar slot 25 extends the length of thehub neck 16 and therefore interrupts the radial shape of thehub neck portion 16. The hub neck portion's inner perimeter defines anaxial opening 21. The diameter of thisaxial opening 21 is slightly larger than the diameter of thedrive axle 90 to allow thesprocket hub 10 to float and oscillate on the drive axle and to compensate for chassis flex and chain bind. - The floating and oscillation of the present invention is generally accomplished by the
sprocket hub 10 andbar notch 25 having a loose fit with thedrive axle 90 andbar 92. Floating in particular is caused by a loose fit between thesprocket hub 10,bar notch 25 and lockingcollar 30 with respect to thedrive axle 90 andbar 92. Oscillation in particular is the horizontal pivotal movement of thesprocket hub 10 about thedrive axle 90. This oscillation is caused by thesprocket hub 10 andbar notch 25 having a loose fit with thedrive axle 90 andbar 92. - The
hub neck portion 16 further comprises a necktop flange 18 and a neckbottom flange 19 both located on the end of thehub neck portion 16 opposite from thehub front face 24. Both the necktop flange 18 and the neckbottom flange 19 have an arc distance d1 in length, where d1 is equal to approximately 1.00 inches in this example. Theouter perimeter 20 of thehub neck portion 16 defines the outer extent of thehub neck portion 16 in a direction parallel to the longitudinal axis of theaxle opening 21. - The locking
collar 30 is generally a circular member with anouter perimeter 40, amiddle perimeter 33 and aninner perimeter 32. Extending outwardly from theouter perimeter 40 in a direction perpendicular to the longitudinal axis of theaxle opening 53 is a raisedportion 41, which houses the collar bore 34, the compression screw hole 36 and compression screw 36 a. - The collar bore 34 is a threaded hole cut in the locking collar
rear face 50 penetrating towards but not through the lockingcollar front face 51. To give the sprocket hub 10 a more rigid structure, an optional stabilizing screw can be inserted into thescrew hole 22 on the hubrear face 23, and pass through the width of thesprocket hub 10, travel along thehub neck portion 16 and thread into the collar bore 34 of the lockingcollar 30 when assembled. The stabilizing screw and collar bore 34 are both optional. - The compression screw hole 36 accepts the compression screw 36 a. Compression screw 36 a is used to fasten the
locking collar 30 to thebar 92 in order to lock thelocking collar 30 to thesprocket hub 10. - The locking
collar front face 51 has abar notch 52 defined on theinner perimeter 32 and extending towards theouter perimeter 40. Thebar notch 52 loosely accepts theaxle groove bar 92 during lockingcollar 30 attachment to thesprocket hub 10. Themiddle perimeter 33 cannot be seen when viewing thelocking collar 30 from the lockingcollar front face 51. - As shown in
FIG. 6 , the locking collarrear face 50 exposes theouter perimeter 40, themiddle perimeter 33 and theinner perimeter 32. Themiddle perimeter 33 is located between theouter perimeter 40 and theinner perimeter 32 but is proximate to the horizontal plane of the locking collarrear face 50. - The
middle perimeter 33 has two curved, elongatedmiddle perimeter lips 39 extending from themiddle perimeter 33 inwardly towards theaxle opening 53. Themiddle perimeter lips 39 extend parallel with the plane of the locking collarrear face 50. Themiddle perimeter lips 39 define twofemale portions 37 around themiddle perimeter 33, each of which have a length of d2, which, in this example, d2 is equal to approximately 1.01 inches. - Located between the locking collar
rear face 50 and the lockingcollar front face 51 is anintermediate surface 54. Theintermediate surface 54 is parallel with the plane of the locking collarrear face 50. There is aflange groove 38 defined between themiddle perimeter lips 39 and theintermediate surface 54. Thisflange groove 38 is spaced such that the necktop flange 18 and the neckbottom flange 19 can fit within theflange grove 38 during attachment of the lockingcollar 30 to thesprocket hub 10, seeFIG. 10 . - When attaching the
sprocket hub 10 and lockingcollar 30 to the drivingaxle 90, theaxle groove bar 92 is first placed into theaxle groove 91 of the drivingaxle 90, as shown inFIGS. 8 and 11 . Then thesprocket hub 10 is slid over the drivingaxle 90 through theaxle opening 21, as shown inFIGS. 9-12 . Thesprocket hub 10 fits loosely over thedrive axle 90 in order to allow thesprocket hub 10 to float and oscillate on thedrive axle 90 to accommodate for chassis flex and chain bind. This floating and oscillation of thesprocket hub 10 on thedrive axle 90 allows for enhanced acceleration of a go kart vehicle. The floating and oscillation of thesprocket hub 10 also helps reduce excessive wear on thehub sprocket hub 10, the gear sprocket and the drive chain. - Another benefit of the float and oscillation design is the alignment compensation when “lead” or “wedge” is set into the rear axle of the go kart vehicle. Lead is when the axle is cocked to allow the rear of the go kart vehicle to travel sideways (fractionally). Wedge is when the axle is cocked to increase the force on either the right or left tire. Both wedge and lead bring the clutch and
sprocket hub 10 out of alignment. The float and oscillating design of thesprocket hub 10 helps to compensate for this misalignment. - The
sprocket hub 10 should be positioned over theaxle groove bar 92 so that thebar slot 25 engages theaxle groove bar 92, seeFIG. 9 . Thehub neck portion 16 can face either direction when placed upon the drivingaxle 90, as long as it can engage the locking collarrear face 50. The lockingcollar 30 is then slid onto the axle throughaxle opening 53. The locking collarrear face 50 should be facing the sprockethub front face 24 when both are positioned on the axle. The necktop flange 18 and the neckbottom flange 19 of thehub neck portion 16 should engage thefemale portions 37 of the lockingcollar 30 during assembly. - Once the locking
collar 30 is generally engaged with thesprocket hub 10 via theneck flanges collar 30 should be turned in either a clockwise direction or counterclockwise direction until the compression screw hole 36 is aligned above thebar 92. This rotation is shown with reference toFIGS. 10 and 11 , showing the unengaged, unrotated position, and the engaged, rotated position shown inFIG. 12 . Upon rotation of the lockingcollar 30, the top and bottom flange, 18 and 19 respectively, are positioned behind themiddle perimeter lips 38, which causes thelocking collar 30 to become attached to thesprocket hub 10. - After this alignment is made, the user should ensure that the
axle groove bar 92 is engaged with thebar notch 52. The compression screw 36A is then tightened to essentially “lock” the lockingcollar 30 into place on thesprocket hub 10. - Once the locking
collar 30 is fastened to the sprockethub neck portion 16, an optional stabilizing screw (not shown) may be inserted through the hubrear face 23 via thescrew hole 22 and attached to the locking collarrear face 50 via the collar bore 34. The step of utilizing this stabilizing screw adds strength and rigidity to theoverall sprocket hub 10 and lockingcollar 30 assembly. This stabilizing screw is optional, however, as the current assembly can function properly without the use of the stabilizing screw. - Generally the present invention is used, on a go kart vehicle or other vehicle, as follows. The vehicle motor spins the clutch, the clutch spins the drive chain, and then the drive chain spins the gear sprocket. The gear sprocket is attached to the
sprocket hub 10 by means of bolts, studs or the like. Thesprocket hub 10 is attached to the drivingaxle 90 by means of theaxle groove bar 92 and to thelocking collar 30 via the compression screw 36A. This attachment causes the gear sprocket andsprocket hub 10 to rotate in unison with the drivingaxle 90, which in turn drives the wheels of the vehicle.
