[0030] As shown in Figs. 1 to 3 In a first aspect, the embodiments of the present application provide a vehicle transmission system, which comprises:

[0031] The drive axle 1 comprises a drive axle body 10, a first suspension 11 and a second suspension 12, the first suspension 11 and the second suspension 12 are located on two ends of the drive axle body 10 in a first direction, wherein the first direction is a direction from the tail of the vehicle to the head of the vehicle, the first suspension 11 is away from the tail of the vehicle, and the second suspension 12 is close to the tail of the vehicle.

[0032] The mounting structure 2 comprises a first mounting part 21 and a second mounting part 22, the first mounting part 21 is used for detachably connecting the first suspension 11, and the second mounting part is used for detachably connecting a subframe 3 included in the vehicle, and the second suspension 12 is detachably connected on the subframe 3.

[0033] It can be seen from the above embodiment that, in the embodiment of the utility model, because drive axle 1 includes drive axle body 10, first suspension 11 and second suspension 12, first suspension 11 and second suspension 12 are located on two ends of drive axle body 10 in first direction, wherein, first direction is the direction from the tail of the vehicle to the head, first suspension 11 is away from the tail of the vehicle, second suspension 12 is close to the tail of the vehicle, mounting structure 2 includes first mounting part 21 and second mounting part 22, first mounting part 21 is used for detachable connection first suspension 11, second mounting part is used for detachable connection auxiliary frame 3 included in the vehicle, second suspension 12 is detachable connected on auxiliary frame 3, therefore, auxiliary frame 3 and drive axle 1 can be connected through mounting structure 2, and detachable connection between drive axle 1 and mounting structure 2, detachable connection between mounting structure 2 and auxiliary frame 3 is formed. In this way, in the case that the type of the vehicle changes and causes the type of drive axle 1 to change, namely, when the relative position of first suspension 11 of drive axle 1 changes, different mounting structures 2 can be replaced through dismounting, namely, the mounting between drive axle 1 and auxiliary frame 3 can be realized, without the need of replacing the structure of auxiliary frame 3, thereby facilitating the differential arrangement of drive axle 1, and reducing the development cost period of different vehicle types.

[0034] In the above embodiment, drive axle 1 is located at the end of the vehicle transmission system, can change the rotation speed and torque from the transmission, and transmit the rotation speed and torque to the driving wheel mechanism. Drive axle 1 can include main reducer, differential, wheel transmission device and drive axle housing, constant velocity universal joint and the like structure.

[0035] Drive axle 1 includes first suspension 11 and second suspension 12, the number of first suspension 11 is equal to the number of second suspension 12, generally, the number of first suspension 11 and the number of second suspension 12 are both even, for example, the number of first suspension 11 is 2, and the number of second suspension 12 is 2. First suspension 11 is away from the tail of the vehicle, namely, first suspension 11 is located at one end of drive axle 1 towards the head of the vehicle, second suspension 12 is close to the tail of the vehicle, namely, second suspension 12 is located at one end of drive axle 1 towards the tail of the vehicle. The head of the vehicle is one end where the cab of the vehicle is located, and the tail of the vehicle is one end away from the cab of the vehicle.

[0036] It should be noted that, during installation, the second suspension 12 can be installed on the auxiliary frame 3 first. Since the size of the auxiliary frame 3 is larger than the size of the drive axle 1, that is, the coverage area of the auxiliary frame 3 is larger than the coverage area of the drive axle 1, therefore, regardless of the change in the specification of the drive axle 1, at least the suspension provided at one end of the drive axle 1 can be connected with the auxiliary frame 3. In the embodiment of the utility model, the second suspension 12 is directly and detachably connected with the auxiliary frame 3. The first suspension 11 is connected with the drive axle 1 through the mounting structure 2, therefore, after the structure of the drive axle 1 is changed, different mounting structures 2 can be replaced to adapt to the structure of the drive axle 1.

[0037] The mounting structure 2 can be any one of a frame-shaped structure, a plate-shaped structure or other types of structures, which are not limited in the embodiment of the utility model. The mounting structure 2 comprises a first mounting portion 21 and a second mounting portion 22. The first mounting portion 21 is used for detachable connection with the first suspension 11, and the second mounting portion 22 is used for detachable connection with the auxiliary frame 3. Both the first mounting portion 21 and the second mounting portion 22 can be a hole shaft structure.

[0038] In some embodiments, the first mounting portion 21 comprises a first hole shaft 211 and a second hole shaft 212. Both the first hole shaft 211 and the second hole shaft 212 are inserted with a first suspension 11.

[0039] In this embodiment, the first hole shaft 211 and the second hole shaft 212 comprised by the first mounting portion 21 are shaft-shaped structures with through holes, therefore, the first suspension 11 can be inserted through the through hole structure in the middle of the first hole shaft 211 and the through hole structure in the middle of the second hole shaft 212. In this way, by assembling the first suspension 11 and the first hole shaft 211 and the first suspension 11 and the second hole shaft 212 in the form of insertion, only the size tolerance of the first hole shaft 211 and the second hole shaft 212 needs to be controlled during preparation, so as to control the assembly error of the first suspension 11, reduce the assembly error in the assembly process and improve the assembly efficiency. It should be noted that the first hole shaft 211 and the second hole shaft 212 can be arranged at intervals in the second direction on the first mounting portion 21, so that the first hole shaft 211 and the second hole shaft 212 can be at different positions in the second direction on the first mounting portion 21, and thus, after the first hole shaft 211 and the second hole shaft 212 are each inserted with a first suspension 11, the two first suspensions 11 are also at different positions in the second direction on the first mounting portion 21.

[0040] In some embodiments, the number of the first suspensions 11 is equal to the number of the second suspensions 11, and both the number of the first suspensions 11 and the number of the second suspensions 11 are at least two.

[0041] In the embodiment, since the number of the first suspensions 11 and the number of the second suspensions 11 are equal, and the number of the first suspensions 11 and the number of the second suspensions 11 are both at least two, the number of the suspensions of the drive axle body 10 close to the direction of the tail of the vehicle and the number of the suspensions of the drive axle body 10 away from the direction of the tail of the vehicle are both multiple, and the number of the suspensions of the drive axle body 10 close to the direction of the tail of the vehicle and the number of the suspensions of the drive axle body 10 away from the direction of the tail of the vehicle are guaranteed to be consistent, which is beneficial to maintaining the balance of the structure of the drive axle body 10.

[0042] In some embodiments, the first mounting portion 21 further comprises a first bushing 213 and a second bushing 214, the first hole shaft 211 is installed in the first bushing 213, and the second hole shaft 212 is installed in the second bushing 214.

[0043] In the embodiment, since the first mounting portion 21 further comprises a first bushing 213 and a second bushing 214, the first hole shaft 211 is installed in the first bushing 213, and the second hole shaft 212 is installed in the second bushing 214, not only can the assembly error between the first hole shaft 211 and the first suspension 11 be compensated by the first bushing 213, and the assembly error between the second hole shaft 212 and the first suspension 11 be compensated by the second bushing 214, but also the vibration of the first suspension 11 during transmission can be reduced by the first bushing 213 and the second bushing 214.

[0044] In some embodiments, the mounting structure 2 comprises a mounting bracket 23, the main body portion of the mounting bracket 23 has a bending structure 231, and the end of the drive axle 1 where the first suspension 11 is installed is further provided with an assembly flange 13, and the assembly flange 13 is arranged in the cavity formed by the bending structure 231.

[0045] In the embodiment, the mounting bracket 23 can be a plate-shaped structure with different mounting surfaces, and the main body portion of the mounting bracket 23 can constitute a U-shaped plate-shaped structure, that is, the main body portion of the mounting bracket 23 has a bending structure 231, and the bending structure 231 is bent towards the direction where the drive axle 1 is located. In this way, since the end of the drive axle 1 where the first suspension 11 is installed is further provided with an assembly flange 13, and the assembly flange 13 is arranged in the cavity formed by the bending structure 231, the assembly flange 13 can be avoided by the bending structure 231, and thus the arrangement of the mounting structure 2 will not affect the normal arrangement of the drive axle 1.

[0046] In some embodiments, the main body portion of the mounting bracket 23 is provided with a weight-reducing through hole 232.

[0047] In this embodiment, the weight-reducing through hole 232 can be a circular arc-shaped through hole, a strip-shaped through hole or a through hole of other shapes, and the embodiments of the present application do not limit this. In this way, in the case that the main body portion of the mounting bracket 23 is provided with the weight-reducing through hole 232, the overall weight of the mounting bracket 23 can be reduced, and a component force can be generated in the area where the weight-reducing through hole 232 is located, so that the strength of the mounting bracket 23 is improved.

[0048] In some embodiments, the main body portion of the mounting bracket 23 is provided with a reinforcing rib 233, and the reinforcing rib 233 extends in the direction from the drive axle body 10 to the auxiliary frame 3.

[0049] In this embodiment, the reinforcing rib 233 can be a protruding structure provided on the main body portion of the mounting bracket 23, and the reinforcing rib 233 can be one or multiple, and can be a strip-shaped protruding structure or a bump structure, or other structures, and the embodiments of the present application do not limit this. In this way, since the reinforcing rib 233 extends in the direction from the drive axle body 10 to the auxiliary frame 3, the stress between the drive axle 1 and the auxiliary frame 3 can be transmitted through the reinforcing rib 233, and thus the strength of the mounting bracket 23 is improved.

[0050] In some embodiments, the second mounting portion 22 includes a first mounting hole 221, a second mounting hole 222 and a third mounting hole 223, the first mounting hole 221 and the second mounting hole 222 are provided on the two end portions of the mounting bracket 23 in the second direction, the third mounting hole 223 is provided in the middle portion of the mounting bracket 23, and the third mounting hole 223 is located between the first mounting hole 221 and the second mounting hole 222, wherein the second direction intersects the first direction. The auxiliary frame 3 is connected with the mounting bracket 23 through the first mounting hole 221, the second mounting hole 222 and the third mounting hole 223.

[0051] In this embodiment, the first mounting hole 221 and the second mounting hole 222 can be provided on the top of the mounting bracket 23 facing the auxiliary frame 3, the first mounting hole 221 and the second mounting hole 222 are located on the two end portions of the mounting bracket 23 in the second direction, the third mounting hole 223 can be provided between the first mounting hole 221 and the second mounting hole 222, the axis of the third mounting hole 223 can intersect the axis of the first mounting hole 221, and at the same time, the axis of the third mounting hole 223 can intersect the axis of the second mounting hole 222, that is, the direction of the third mounting hole 223 is different from the direction of the first mounting hole 221 and the direction of the second mounting hole 222. In this way, in the case that the auxiliary frame 3 is connected with the mounting bracket 23 through the first mounting hole 221, the second mounting hole 222 and the third mounting hole 223, multiple connection points can be provided between the auxiliary frame 3 and the mounting bracket 23, and the connection points between the auxiliary frame 3 and the mounting bracket 23 can be dispersed at various positions, so that the fastening of the connection between the auxiliary frame 3 and the mounting bracket 23 is ensured.

[0052] In some embodiments, the lines between the first mounting hole 221, the second mounting hole 222 and the third mounting hole 223 form a triangle.

[0053] In this embodiment, since the lines between the first mounting hole 221, the second mounting hole 222 and the third mounting hole 223 form a triangle, the connecting points between the auxiliary frame 3 and the mounting frame 23 form a triangular distribution, and the triangle has stability, which can further improve the stability of the connection between the auxiliary frame 3 and the mounting frame 23.
