[0030] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0031] Reference below Figure 1-Figure 4 The vehicle axle 100 according to the embodiment of the present invention is described, and the vehicle axle 100 can be applied to a vehicle.

[0032] Combination Figure 1-Figure 4 As shown, the vehicle axle 100 according to the utility model can mainly include: a steering knuckle 10, a bent tube beam 20 and a fastener 30, wherein a first through hole 11 is arranged on the steering knuckle 10, the bent tube beam 20 is arranged on one side of the steering knuckle 10 and is provided with a second through hole 211, the second through hole 211 corresponds to the first through hole 11, the fastener 30 sequentially penetrates the first through hole 11 and the second through hole 211 and connects and fixes the steering knuckle 10 and the bent tube beam 20, a first avoidance groove 12 is arranged on the outer side of the steering knuckle 10 corresponding to the first through hole 11, one end of the fastener 30 is located in the first avoidance groove 12 and is flush with the side surface of the steering knuckle 10.

[0033] Specifically, by providing the first through hole 11 on the steering knuckle 10 and the second through hole 211 on the curved tube beam 20, the structures of the first through hole 11 and the second through hole 211 are simple, which facilitates the processing of the steering knuckle 10 and the curved tube beam 20. By making the second through hole 211 correspond to the first through hole 11, it is only necessary to penetrate the first through hole 11 and the second through hole 211 with the fastener 30, and the first through hole 11 and the second through hole 211 can be locked by rotating the fastener 30, so that the steering knuckle 10 can be fixed on the curved tube beam 20 to achieve the installation of the steering knuckle 10 on the axle 100. In addition, by reversing the fastener 30, the fastener 30 and the first through hole 11 and the second through hole 211 can be separated from the locked state, and then the fastener 30 can be removed from the first through hole 11 and the second through hole 211, so that there is no locking force between the steering knuckle 10 and the curved tube beam 20, and the steering knuckle 10 can be easily removed, so that the steering knuckle 10 can be flexibly disassembled and assembled on the curved tube beam 20.

[0034] In this way, a detachable connection between the steering knuckle 10 and the bent tube beam 20 can be achieved. On the one hand, this can simplify the connection operation between the steering knuckle 10 and the bent tube beam 20, which not only saves installation time and improves the installation convenience of the axle 100, but also ensures the structural reliability of the steering knuckle 10 on the bent tube beam 20, and ensures the structural reliability of the axle 100 and even the vehicle. On the other hand, when the steering knuckle 10 fails, the steering knuckle 10 can be easily disassembled and replaced without replacing the entire axle 100, which can improve the maintenance economy of the entire vehicle.

[0035] Furthermore, the steering knuckle 10 is located on the outside of the bent tube beam 20, so that the fastener 30 is sequentially penetrated through the first through hole 11 and the second through hole 211, that is, the fastener 30 is arranged from the outside to the inside, one end of the fastener 30 is located on the outside, and the other end of the fastener 30 is located on the inside. By arranging a first avoidance groove 12 on the outside of the steering knuckle 10 corresponding to the first through hole 11, and making the end of the fastener 30 located on the outside be located in the first avoidance groove 12, the fastener 30 and the side of the steering knuckle 10 are flush with each other, so that the structural design of the steering knuckle 10 can be further optimized, and it is avoided that one end of the fastener 30 protrudes from the outer surface of the steering knuckle 10, causing the fastener 30 to interfere with other components, causing abnormal driving noise or even structural damage, thereby ensuring the normal operation of the axle 100 and even the vehicle.

[0036] Therefore, by providing a first through hole 11 on the steering knuckle 10, the bent tube beam 20 is provided on one side of the steering knuckle 10 and provided with a second through hole 211, the second through hole 211 corresponds to the first through hole 11, the fastener 30 sequentially penetrates the first through hole 11 and the second through hole 211 and connects and fixes the steering knuckle 10 and the bent tube beam 20, and a first avoidance groove 12 is provided on the outer side of the steering knuckle 10 corresponding to the first through hole 11, one end of the fastener 30 is located in the first avoidance groove 12 and is flush with the side of the steering knuckle 10. In this way, on the premise that a detachable connection between the steering knuckle 10 and the bent tube beam 20 can be achieved, the structural design of the steering knuckle 10 can be further optimized to avoid interference between the fastener 30 and other components, thereby improving the reliability of the axle 100 and even the vehicle.

[0037] Combination Figure 1-Figure 4 As shown, the fastener 30 is a mounting bolt, which may mainly include a rod 31 and a head 32. The head 32 is arranged at one end of the rod 31. The rod 31 is sequentially penetrated by a first through hole 11 and a second through hole 211. The head 32 is arranged in the first avoidance groove 12 and is flush with the side surface of the steering knuckle 10. The head 32 is provided with knurling and is interference fit with the first avoidance groove 12.

[0038] Specifically, the fastener 30 can be set as a mounting bolt, and a mounting nut 50 can be provided to cooperate therewith, so that during assembly, the rod 31 can be penetrated with the first through hole 11 and the second through hole 211 in sequence, and when the head 32 moves to the first avoidance groove 12 and abuts against the inner wall of the first avoidance groove 12, the fastener 30 moves to the extreme position. At this time, the head 32 is flush with the side of the steering knuckle 10, and it is only necessary to thread the mounting nut 50 and the end of the rod 31 away from the head 32 to achieve the fastening effect of the fastener 30 and realize the stable connection between the steering knuckle 10 and the bent tube beam 20.

[0039] Furthermore, knurling can be provided on the head 32 of the fastener 30, so that after the fastener 30 is successively penetrated with the first through hole 11 and the second through hole 211, the knurling can be made to have an interference fit with the first avoidance groove 12, that is, an interference fit between the fastener 30 and the steering knuckle 10 can be achieved, thereby avoiding the rotation of the fastener 30 while meeting the assembly requirements, improving the problem of coaxial rotation of conventional bolt and nut assembly, and thus facilitating the disassembly and assembly of the fastener 30 and facilitating after-sales maintenance.

[0040] Combination Figure 4 As shown, the rod portion 31 may include a first rod portion 311, a second rod portion 312, and a third rod portion 313 connected in sequence, one end of the first rod portion 311 away from the second rod portion 312 is connected to the head portion 32, the diameter of the first rod portion 311 is larger than the diameter of the second rod portion 312, and the diameter of the second rod portion 312 is the same as the diameter of the third rod portion 313. Also, the second through hole 211 may include a first hole portion 111 and a second hole portion 112, the first hole portion 111 is connected between the first avoidance groove 12 and the second hole portion 112, the aperture of the first avoidance groove 12 is larger than the aperture of the first hole portion 111, and the aperture of the first hole portion 111 is larger than the aperture of the second hole portion 112.

[0041] After the first through hole 11 and the second through hole 211 are sequentially formed on the rod portion 31, the first rod portion 311 corresponds to the first hole portion 111, the second rod portion 312 corresponds to the second hole portion 112, at least a portion of the third rod portion 313 corresponds to the second through hole 211, and at least a portion of the third rod portion 313 corresponds to the mounting nut 50.

[0042] By also arranging knurling on the outer periphery of the first rod portion 311, the first rod portion 311 and the first hole portion 111 are interference fit, which can further achieve an interference fit between the fastener 30 and the steering knuckle 10, thereby more effectively avoiding the fastener 30 from rotating while meeting the assembly requirements, and improving the coaxial rotation problem of conventional bolt and nut assembly, thereby facilitating the disassembly and assembly of the fastener 30 and facilitating after-sales maintenance.

[0043] By configuring the second rod portion 312 as a bare rod portion, not only is it convenient to insert the second rod portion 312 , but also the manufacturing cost of the mounting bolts can be reduced.

[0044] By arranging an external thread on the outer periphery of the third rod portion 313 and an internal thread on the circumferential inner wall of the second through hole 211, the third rod portion 313 can be threadedly connected not only to the mounting nut 50, but also to the connecting flange 21, thereby improving the connection stability and reliability between the steering knuckle 10 and the connecting flange 21.

[0045] Combination Figure 1 and Figure 4As shown, the axle 100 may further include a brake disc 40, which is disposed on the side of the steering knuckle 10 away from the curved tube beam 20, and the fastener 30 is spaced apart from the brake disc 40. Specifically, the brake disc 40 is a friction pair on a disc brake, and the brake disc 40 is disposed on the side of the steering knuckle 10 away from the curved tube beam 20, so that the brake disc 40 is close to the wheel. When the vehicle is moving, the brake disc 40 can rotate with the wheel, and when the vehicle brakes, the caliper clamps the brake disc 40 for friction braking, which plays a role in slowing down or stopping the vehicle, thereby ensuring the normal operation of the axle 100 and even the vehicle.

[0046] Furthermore, by making the fastener 30 close to one end of the brake disc 40, that is, the head 32 of the fastener 30 extends into the first avoidance groove 12, and the outer surface of the head 32 is flush with the steering knuckle 10, the fastener 30 and the brake disc 40 can be spaced apart, thereby ensuring the gap between the fastener 30 and the brake disc 40, avoiding interference between the fastener 30 and the brake disc 40, resulting in abnormal driving noise or even structural damage, thereby ensuring the normal operation of the axle 100 and even the vehicle. It should be noted that a brake disc cover 41 is provided outside the brake disc 40 to protect the structure of the brake disc 40. The fastener 30 is not only spaced apart from the brake disc 40, but also spaced apart from the brake disc cover 41, which will not be described in detail here.

[0047] Combination Figure 1-Figure 4 As shown, a connecting flange 21 is provided at one end of the bent tube beam 20, a second through hole 211 is provided at the connecting flange 21, the connecting flange 21 and the steering knuckle 10 are fitted together, and the connecting flange 21 and the wheel rim of the vehicle are spaced apart.

[0048] Specifically, by providing a connecting flange 21 at one end of the bent tube beam 20 and providing a second through hole 211 on the connecting flange 21, when assembling the vehicle axle 100, the connecting flange 21 can be fitted with the steering knuckle 10, and then the fastener 30 is sequentially penetrated through the first through hole 11 on the steering knuckle 10 and the second through hole 211 on the connecting flange 21 to achieve the connection between the bent tube beam 20 and the steering knuckle 10. This can not only increase the contact area between one end of the bent tube beam 20 and the steering knuckle 10, but also facilitate the connection between the steering knuckle 10 and the bent tube beam 20, and improve the connection stability between the steering knuckle 10 and the bent tube beam 20, but also achieve a dustproof function through the mutual fit between the connecting flange 21 and the steering knuckle 10.

[0049] Furthermore, one end of the axle 100 is connected to the wheel, and at least part of the end of the axle 100 is located on the inner periphery of the wheel rim of the vehicle. By setting the connecting flange 21 and the wheel rim of the vehicle at a distance, interference between the connecting flange 21 and the wheel rim can be avoided to cause abnormal noise during driving or even structural damage, thereby ensuring the normal operation of the axle 100 and even the vehicle.

[0050] Furthermore, combined with Figure 2 and Figure 3 As shown, the connecting flange 21 is an asymmetric structural member. Specifically, considering that the connecting flange 21 is connected to the steering knuckle 10, and the steering knuckle 10 is connected to the wheel hub of the vehicle, different from setting the connecting flange as a symmetrical structural member, for example, a disc-shaped one, by setting the connecting flange 21 as an asymmetric structural member, the connecting flange 21 can be adaptively adjusted and avoided according to other nearby parts, thereby avoiding interference and ensuring the normal operation of the axle 100 and even the vehicle.

[0051] Furthermore, combined with Figure 1 and Figure 3 As shown, a bearing mounting hole 13 for mounting a wheel hub bearing 60 is provided on the steering knuckle 10 , and a second avoidance groove 212 is provided on one side of the connecting flange 21 adjacent to the bearing mounting hole 13 , and the second avoidance groove 212 is used to avoid the bearing mounting hole 13 .

[0052] Specifically, a wheel hub bearing 60 is further provided on the side of the steering knuckle 10 away from the bent tube beam 20. The outer ring of the wheel hub bearing 60 is connected to the wheel hub of the vehicle, and the inner ring of the wheel hub bearing 60 is connected to the drive shaft. By providing a bearing mounting hole 13 on the steering knuckle 10, the wheel hub bearing 60 can at least partially penetrate the bearing mounting hole 13 on the steering knuckle 10. By providing a second avoidance groove 212 on the side of the connecting flange 21 adjacent to the bearing mounting hole 13, the second avoidance groove 212 can avoid the bearing mounting hole 13, thereby ensuring the normal connection between the drive shaft and the wheel hub bearing 60, avoiding interference between the connecting flange 21 and the wheel hub bearing 60 and the drive shaft, resulting in abnormal driving noise or even structural damage, thereby ensuring the normal operation of the axle 100 and even the vehicle.

[0053] Combination Figure 2 and Figure 3 As shown, the connecting flange 21 is provided with a first positioning portion 213, and the steering knuckle 10 is provided with a second positioning portion 14, and the first positioning portion 213 and the second positioning portion 14 are positioned and matched. Specifically, when the connecting flange 21 and the steering knuckle 10 are fitted to each other, the first positioning portion 213 on the connecting flange 21 and the second positioning portion 14 on the steering knuckle 10 can be positioned and matched, so that not only the connecting flange 21 and the steering knuckle 10 can be positioned quickly and accurately, which is conducive to saving installation time and reducing production costs, but also the positions of the connecting flange 21 and the steering knuckle 10 after positioning can be kept unchanged, and the misalignment of the connecting flange 21 and the steering knuckle 10 after fitting can be prevented, thereby improving the installation convenience of the steering knuckle 10 and the connecting flange 21, and improving the assembly convenience of the steering knuckle 10 and the bent tube beam 20.

[0054] Furthermore, combined with Figure 2 and Figure 3As shown, the first positioning portion 213 is a positioning protrusion, and the second positioning portion 14 is a positioning hole, and the positioning protrusion extends into the positioning hole and is positioned and matched with the positioning hole. Specifically, the first positioning portion 213 can be set as a positioning protrusion, so that the positioning protrusion protrudes in the axial direction of the connecting flange 21, and the second positioning portion 14 can be set as a positioning hole, and the positioning hole is concave in the axial direction of the steering knuckle 10.

[0055] In this way, the positioning cooperation between the first positioning portion 213 and the second positioning portion 14 is actually the positioning cooperation between the positioning protrusion and the positioning hole. The positioning cooperation between the first positioning portion 213 and the second positioning portion 14 can be achieved by simply extending the positioning protrusion into the positioning hole so that the positioning protrusion and the positioning hole are positioned and matched, which can not only improve the speed and accuracy of the positioning cooperation between the first positioning portion 213 and the second positioning portion 14, but also improve the stability and reliability of the positioning cooperation between the first positioning portion 213 and the second positioning portion 14.

[0056] In addition, the positioning protrusion has a simple structure, which is convenient for processing on the connecting flange 21, and the positioning hole has a simple structure, which is convenient for processing on the steering knuckle 10, so that the connecting flange 21 and the steering knuckle 10 can have simple structures and be convenient for processing and manufacturing. In a specific embodiment of the utility model, the positioning protrusion and the positioning hole can be annular.

[0057] Combination Figure 1-Figure 4 As shown, both the first perforation 11 and the second perforation 211 are multiple, and the multiple first perforations 11 and the multiple second perforations 211 are arranged in one-to-one correspondence. Correspondingly, there are also multiple fasteners 30. With such an arrangement, the connection positions of the fasteners 30 on the steering knuckle 10 and the bent tube beam 20 can be increased by increasing the number of the first perforations 11 and the second perforations 211, so that the multiple fasteners 30 connect the steering knuckle 10 and the bent tube beam 20, which can improve the connection reliability of the steering knuckle 10 and the bent tube beam 20, and can improve the structural reliability of the axle 100.

[0058] Optionally, a plurality of first perforations 11 may be circumferentially spaced apart on the steering knuckle 10, and a plurality of second perforations 211 may be circumferentially spaced apart on the bent tube beam 20, so that the distribution of the fastening force may be more uniform and reasonable, the connection reliability between the steering knuckle 10 and the bent tube beam 20 may be further improved, and the structural reliability of the axle 100 may be improved.

[0059] The vehicle according to the utility model may mainly include: the above-mentioned axle 100. Specifically, by arranging the axle 100 on the vehicle, under the premise of ensuring the normal operation of the vehicle, not only can the production cycle be shortened and the production cost be reduced, but also the maintenance economy and disassembly and assembly convenience of the vehicle can be improved, thereby improving the user experience and enhancing the product competitiveness of the vehicle.
