Description

Vehicle bridge and automobile
Technical field
The present invention relates to structure design of automobile technical field, particularly relate to a kind of vehicle bridge.The invention still further relates to a kind of automobile.
Background technique
Differential mechanism is the vitals in automobile drive axle, and its major function makes the left and right driving of ransaxle take turns the differential had required by automobile running kinology, and power distribution taken turns to left and right driving.But " differential is not poor to be turned round " of open differential torque distribution performance such as namely, has but had a strong impact on the passing ability of automobile, traction property and driving safety.
Most of automobile is all right to be sailed on the reasonable road surface of attachment condition, nearly all have employed that structure is simple, the common symmetric formula cone planetary gear differential mechanism of stable working, easily manufactured, good reliability; And for often travelling at the offroad vehicle of muddy, soft dirt road or cross-country locality or lorry, will limited slip differential be adopted to prevent falling into car because certain side drives wheel slip.General employing locking differential and limited slip differential improve the passing ability of automobile, traction property and driving safety, although and locking differential simply operation inconvenience, use less, be generally used on minority heavy goods vehicle.
When automobile left and right driving wheel travels on the ground that attachment condition is different, limited slip differential can in order to try (automatically or by control) make most of torque even all torque distribution to compare a good side drive wheel to attachment condition, thus improve the passing ability of automobile, traction property and driving safety.Limited slip differential has a variety of, friction-disc cone gear differential mechanism and precompressed friction-disc cone gear differential mechanism are wherein two kinds, because both have the advantages such as structure is simple, stable working, technique inheritance are good, so it is wider to belong to using scope in limited slip differential.
If T 1for the torque on differential mechanism rotating faster differential gear, ω 1for rotating the rotating speed of differential gear faster, T 2for rotating the torque on slower differential gear, ω 2for rotating the rotating speed of slower differential gear.The efficiency eta of differential mechanism dwhen referring to that differential carrier does not turn, the ratio of output power and input power when a semiaxis drives another semiaxis, because the rotating speed of now two-semiaxle is equal, i.e. ω 12, so
η D = T 1 ω 1 T 2 ω 2 = T 1 T 2 = 1 K - - - ( 1 )
Wherein, K is locking coefficient, represents the maximum multiple that the torque of both sides driving wheel may differ, K=T 2/ T 1, that is efficiency eta of differential mechanism dfor the inverse of its locking coefficient.From above formula, the locking coefficient K of differential mechanism and differential mechanism efficiency eta dbe inversely proportional to.
The inner friction torque of differential mechanism is larger, and its locking coefficient is also just large, will make the efficiency eta of differential mechanism dlower, then be more conducive to both sides and drive redistributing of wheel torque, be more conducive to the passing ability improving automobile.Although there is large internal frictional losses the efficiency of differential mechanism low showing, this situation only just occurs when left and right wheel has remarkable speed discrepancy, and this speed discrepancy is little in the ordinary course of things, and therefore the fricting loss power of differential mechanism is not remarkable.When driving wheels rotating speed is equal, the fricting loss power of differential mechanism is zero.When automobile is turned with min. turning radius, the fricting loss power of differential mechanism reaches maximum value.
Theoretical according to differential mechanism, the transmission efficiency η of differential mechanism dTfor:
η D T = 1 - B 2 R × 1 - η D 1 + η D - - - ( 2 )
Wherein, B is wheelspan, and R is radius of turn.From formula (2), the transmission efficiency η of differential mechanism dTbe different from the efficiency eta of differential mechanism d, the latter is only relevant with the structure of differential mechanism, and the former is also relevant with the radius of turn R of automobile back driving axle intermediate point and wheelspan B, and changes with the change of R.Can find out from formula (2), even if the efficiency eta of differential mechanism dvery low, the transmission efficiency η of differential mechanism dTstill higher, substantially more than 0.9.The efficiency eta of Here it is why some high-friction-type no-spin lockup dalthough very low, but still adopted reason.
With in the cone planetary gear limited slip differential of friction disk or friction plate in conventional art, when automobile turning or single wheel trackslip on road surface, planetary pinion rotation, plays differential action, and the rotating speed of left and right half gear is not etc.Due to the existence of speed discrepancy and the effect of axial force, produce friction torque trackslipping between driving and driven friction plate simultaneously, torque and the friction plate quantity of its numerical values recited and differential mechanism transmission are directly proportional, and its direction is contrary with the rotation direction turning semiaxis soon, identical with the rotation direction of slow-speed semiaxis.The result of the inner friction torque effect of bigger numerical, makes the torque of slow-speed semiaxis transmission obviously increase.Friction disk type differential design is simple, and stable working, locking coefficient K can reach 0.6 ~ 0.7 or higher.
But the torque that can bear between friction plate or between slider cam is relatively little, can not transmitting large torque.Helical spring is then arranged between two differential gears by precompressed friction-disc cone gear differential mechanism, causes helical spring installation space more limited, causes the passing ability of automobile, traction property and driving safety not still to be very desirable.

In order to make those skilled in the art understand technological scheme of the present invention better, below in conjunction with accompanying drawing, the present invention is further detailed.
As Figure 1-5, the embodiment of the present invention provides a kind of vehicle bridge, this vehicle bridge comprises main reducing gear lid 41, axle housing 42, brake drum 43, wheel hub 44, first semiaxis 45, second semiaxis and limited slip differential, main reducing gear lid 41 is fixed with axle housing 42, brake drum 43 and wheel hub 44 are fixed, wheel hub 44 is rotatably assorted by hub bearing 46 and axle housing 42, limited slip differential comprises the first output shaft 11, clutch shaft bearing 12, first differential carrier 13, first helical spring 14, first gear 15, second output shaft 21, second bearing 22, second differential carrier 23, second helical spring 24, second gear 25, cross axle 31, planetary pinion 32 and master subtract driven wheel of differential 33, wherein:
First output shaft 11 and the second output shaft 21 are respectively used to fix with the first semiaxis 45 and the second semiaxis, drive left side wheel and right side wheels to rotate with this by brake drum 43 and wheel hub 44; Clutch shaft bearing 12 and the second bearing 22 are installed on the first differential carrier 13 and the second differential carrier 23 respectively; First differential carrier 13 is fixedly connected with by bolt with the second differential carrier 23, and the first differential carrier 13 subtracts driven wheel of differential 33 with master and fixes; First gear 15 and the second gear 25 are fixed on the end of the first output shaft 11 and the second output shaft 21 respectively by the first end cap 16 and the second end cap 26; Cross axle 31 is for installing four planetary pinions 32, each planetary pinion 32 all engages with the first gear 15 and the second gear 25, master subtracts driven wheel of differential 33 and is then fixed on the first differential carrier 13, subtracts driven wheel of differential 33 drive the first differential carrier 13 to rotate with this by master.
First helical spring 14 is set on the first output shaft 11, second helical spring 24 is set on the second output shaft 21, on the semiaxis connecting end that the two ends of the first helical spring 14 act on the first output shaft 11 respectively and the first differential carrier 13, on the semiaxis connecting end that the two ends of the second helical spring 24 act on the second output shaft 21 respectively and the second differential carrier 23.Particularly, one end of the first helical spring 14 and the semiaxis connecting end of the first output shaft 11 abut against, and the other end and the first differential carrier 13 abut against; One end of second helical spring 24 and the semiaxis connecting end of the second output shaft 21 abut against, and the other end and the second differential carrier 23 abut against.
It should be noted that, above-mentioned vehicle bridge can be bilateral symmetry, and therefore each technological scheme provided above and hereinafter of the embodiment of the present invention all can adopt bilateral symmetry.
When the driving wheel of automobile turning or its certain side is absorbed in the less road surface of coefficient of attachment and reaches limit of adhesion and skid, left and right driving wheel produces speed discrepancy.The now rotating speed n of the first differential carrier 13 0with the rotating speed n of the first gear 15 2, the second gear 25 rotating speed n 1all unequal, work as n 1> n 2time, there is n 1> n 0> n 2rotation speed relation.Due to speed discrepancy existence and the first helical spring 14 and the second helical spring 24 compresses the first differential carrier 13 respectively and the second differential carrier 23 makes to produce friction torque between the first differential carrier 13 and the first helical spring 14, between the second differential carrier 23 and the second helical spring 24, the size of the impacting force of the size of this friction torque and the friction factor between friction element and the first helical spring 14 and the second helical spring 24 is relevant, the direction of friction torque and n 1and n 0or n 2and n 0between relative rotation speed relevant, according to n 1, n 2, n 0the rotation speed relation of three obtains: the friction torque of rotating speed differential gear (being installed on the gear on the first output shaft 11 and the second output shaft 21 in limited-slip differential) side faster, the sense of rotation of its direction and rotating speed differential gear is faster contrary, and it is negative for being worth; The friction torque of the differential gear side that rotating speed is slower, the sense of rotation of the differential gear that its direction is slower with rotating speed is identical, is worth for just.Now transfer to the slower differential gear side of rotating speed just as part driving moment by the differential gear side that rotating speed is slower.Therefore the driving moment of the differential gear that rotating speed is slower will be greater than the driving moment of rotating speed differential gear faster.So, as long as there is speed discrepancy, the limited slip differential that the embodiment of the present invention provides just can make most of torque even all torque distribution to compare a good side drive wheel to attachment condition, thus improve the passing ability of automobile, traction property and driving safety.
To sum up, after adopting above-mentioned limited slip differential, the rigidity of the first helical spring 14 and the second helical spring 24 can be increased, and then increase the frictional force in limited slip differential, then improve locking coefficient, realize anti-slip function when vehicle travels.Compared to friction-disc cone gear differential mechanism, the moment that the first helical spring 14 and the second helical spring 24 can transmit is larger; Simultaneously, above-mentioned first helical spring 14 and the second helical spring 24 are all arranged at outside the differential gear of limited slip differential, therefore rigidity and the size of the first helical spring 14 and the second helical spring 24 can be set according to demand flexibly, make the non-skid property of limited slip differential better, improve the passing ability of automobile, traction property and driving safety with this.
In above-mentioned limited slip differential, if only produce friction torque by the compression between the first helical spring 14 and the first differential carrier 13, then because area of contact is between the two less, the friction torque produced is relatively little.Accordingly, the limited slip differential that the embodiment of the present invention provides also comprises the first spring seat 17 be set on the first output shaft 11, and this first spring seat 17 is disk-like structure, and the first helical spring 14 is acted on the first differential carrier 13 by the first spring seat 17.Now, the first helical spring 14 directly compresses the first spring seat 17, and area of contact between the first spring seat 17 and the first differential carrier 13 is larger, makes to produce larger friction torque between the first spring seat 17 and the first differential carrier 13.
In like manner, the limited slip differential that the embodiment of the present invention provides also can comprise the second spring seat 27 be set on the second output shaft 21 further, this second spring seat 27 is disk-like structure, and the second helical spring 24 is acted on the second differential carrier 23 by the second spring seat 27.
In concrete structure, because one end that the first differential carrier 13 contacts with the first spring seat 17 is less, make the area of contact between the first spring seat 17 and the first differential carrier 13 still large not, therefore, in the embodiment of the present invention, limited slip differential also comprises and to form first of integral structure with the first spring seat 17 and to rub conical ring 18, this the first friction conical ring 18 has the first conical surface fitted with the internal surface of the first differential carrier 13, relative to the surface of the first output shaft 11, aforementioned first conical surface tilts near the direction on the surface of laterally closer first output shaft 11 of the first differential carrier 13.The internal surface of the first differential carrier 13 refers to surface relative with the first output shaft 11 on the first differential carrier 13, and the surface of the first output shaft 11 then refers to the annular outer surface of the first output shaft 11.
After adopting this kind of structure, force transmission to the first is rubbed on conical ring 18 by the first spring seat 17 by the first helical spring 14, makes the first friction conical ring 18 compress the first differential carrier 13.Therefore, can to rub the tapering of conical ring 18 by reasonable design first, the area of contact between the first friction conical ring 18 and the first differential carrier 13 can be increased considerably.In addition, the first spring seat 17 and first conical ring 18 one that rubs is processed, and makes the transmission of active force have higher efficiency.
In like manner, in order to strengthen aforementioned techniques effect, above-mentioned limited slip differential also can comprise further and to form second of integral structure with the second spring seat 27 and to rub conical ring 28, this the second friction conical ring 28 has the second conical surface fitted with the internal surface of the second differential carrier 23, relative to the surface of the second output shaft 21, the second conical surface tilts near the surface of laterally closer second output shaft 21 of the second differential carrier 23.The internal surface of the second differential carrier 23 refers to surface relative with the second output shaft 21 on the second differential carrier 23, and the surface of the second output shaft 21 then refers to the annular outer surface of the second output shaft 21.
Aforesaid first conical surface and second conical surface all can be set to curved surface, but for the ease of processing, the one in first conical surface and second conical surface can be set to plane, or both are all set to plane.In addition, when first conical surface and/or second conical surface are the conical surface, along with the wearing and tearing that the first friction conical ring 18 and the first differential carrier 13, second rub between conical ring 28 and the second differential carrier 23, first friction conical ring 18 and the second friction conical ring 28 can move relative to the first output shaft 11 and the second output shaft 21 respectively, even if make both occur wearing and tearing still can respectively with the first differential carrier 13 and the second differential carrier 23 reliable contacts, then transmit friction torque better.
Alternatively, the first spring seat 17 has the first limited ring towards the side of the first helical spring 14, the first helical spring 14 is positioned at the inner side of this first limited ring.Because the first helical spring 14 is set in after on the first output shaft 11, it can occur rocking relative to the first output shaft 11, and the first limited ring then can limit rocking of the first helical spring 14, makes the first helical spring 14 can transmitting forces more reliably.Particularly, above-mentioned first limited ring can be processed with the first spring seat 17 one, and both are mutually vertical.In like manner, the second spring seat 27 has the second limited ring towards the side of the second helical spring 24, the second helical spring 24 is positioned at the inner side of the second limited ring.
In specific embodiment, the semiaxis connecting end of the first output shaft 11 can comprise the first mounting cylinder and first protuberance fixing with this first mounting cylinder that are fixedly connected with the first semiaxis 45, and this first protuberance keeps off with the first helical spring 14 phase and connecing.Now, the first protuberance can limit the position of the first helical spring 14 on the first output shaft 11, prevents the first helical spring 14 from coming off from the first output shaft 11 better with this.In like manner, the semiaxis connecting end of the second output shaft 21 comprises the second mounting cylinder and second protuberance fixing with this second mounting cylinder that are fixedly connected with the second semiaxis, and this second protuberance keeps off with the second helical spring 24 phase and connecing.
After adopting above-mentioned each technological scheme, when vehicle is kept straight on, according to the formula (2) described in background technique, radius of turn R is infinitely great, the transmission efficiency η of differential mechanism dTbe do not relatively rotate between the 1, first gear 15 and the second gear 25, the frictional force produced by helical spring does not cause loss.When vehicle is turned with min. turning radius, can find out according to formula (2), even if the efficiency of limited slip differential is very low, the transmission efficiency of limited slip differential still obtains higher numerical value, as shown in Figure 6, therefore the limited slip differential that provides of the embodiment of the present invention is little in the impact of Ackermann steer angle on transmission of power.
Based on said structure, the embodiment of the present invention also provides a kind of automobile, and this automobile comprises the vehicle bridge described by above-mentioned arbitrary technological scheme.Because above-mentioned vehicle bridge has above-mentioned technique effect, the automobile comprising this vehicle bridge also should have corresponding technique effect, repeats no more herein.
Mode above only by illustrating describes some one exemplary embodiment of the present invention, undoubtedly, for those of ordinary skill in the art, when without departing from the spirit and scope of the present invention, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the claims in the present invention protection domain.
