[0029] 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.

[0030] See the figure below for reference Figure 1-Figure 4 A vehicle axle 100 according to an embodiment of the present invention is described, and the vehicle axle 100 can be applied to a vehicle.

[0031] Combination Figure 1-Figure 4As shown, the axle 100 according to the embodiment of the utility model can mainly include: a bent tube beam 10 and a steering knuckle 20, wherein a first connecting flange 11 is provided at one end of the bent tube beam 10, and a second connecting flange 21 is provided on the steering knuckle 20, the first connecting flange 11 and the second connecting flange 21 are correspondingly fitted to each other, and the first connecting flange 11 and the second connecting flange 21 are detachably connected and fixed. Specifically, the first connecting flange 11 is provided at one end of the bent tube beam 10, which can not only increase the area of ​​one end of the bent tube beam 10, but also facilitate the installation of the steering knuckle 20 and the bent tube beam 10, and also realize the dustproof function of the bent tube beam 10. The second connecting flange 21 is provided at one end of the steering knuckle 20, which can increase the area of ​​one end of the steering knuckle 20, and facilitate the installation of the steering knuckle 20 and the bent tube beam 10.

[0032] Furthermore, the first connection flange 11 and the second connection flange 21 are correspondingly fitted to each other, which is conducive to enhancing the stability of power transmission between the first connection flange 11 and the second connection flange 21. In addition, the first connection flange 11 and the second connection flange 21 can be disassembled, so that the steering knuckle 20 and the curved tube beam 10 can be disassembled. When the steering knuckle 20 needs to be repaired and replaced, the steering knuckle 20 can be removed from the curved tube beam 10 by disassembling the first connection flange 11 and the second connection flange 21, so that it is convenient to repair and replace the steering knuckle 20. In this way, the steering knuckle 20 can be disassembled and repaired without disassembling and replacing the curved tube beam 10. The replaced steering knuckle 20 can continue to be connected to the first connection flange 11 through its second connection flange 21, and then the repaired and replaced steering knuckle 20 can be connected and fixed to the curved tube beam 10, so that the disassembly and assembly flexibility of the steering knuckle 20 can be improved, which can facilitate the repair and modification of the vehicle.

[0033] In the embodiment of the utility model, a plurality of first through-holes 111 are provided on the bent tube beam 10, and a plurality of second through-holes 211 are provided on the steering knuckle 20, and the plurality of first through-holes 111 correspond to the plurality of second through-holes 211 one by one. After the plurality of fasteners 30 pass through the plurality of first through-holes 111 and the plurality of second through-holes 211 respectively, the first through-holes 111 and the second through-holes 211 can be locked by rotating the fasteners 30, so that the first connecting flange 11 and the second connecting flange 21 can be connected and fixed, so that the steering knuckle 20 is connected and fixed to the bent tube beam 10. The utility model sets the steering knuckle 20 and the bent tube beam 10 separately, and then connects and fixes the first connecting flange 11 and the second connecting flange 21 by the fasteners 30. Such a connection method can not only simplify the connection operation of the steering knuckle 20 and the bent tube beam 10, save installation time, and improve the installation convenience of the axle 100, but also ensure the structural reliability of the steering knuckle 20 on the bent tube beam 10, and ensure the structural reliability of the axle 100, which is conducive to ensuring the structural reliability of the whole vehicle.

[0034] Furthermore, reversing the fastener 30 can release the fastener 30 from the locked state with the first through hole 111 and the second through hole 211, and then the fastener 30 can be taken out from the first through hole 111 and the second through hole 211, so that the first connecting flange 11 and the second connecting flange 21 can be separated, and the steering knuckle 20 can be easily removed. During the use of the vehicle, if the steering knuckle 20 fails, the steering knuckle 20 can be easily disassembled and replaced without replacing the entire axle 100, which can improve the maintenance economy of the entire vehicle.

[0035] According to some embodiments of the utility model, at least one first perforation 111 is arranged on the left side of the first connecting flange 11, and at least one second perforation 211 is arranged on the left side of the second connecting flange 21, and the second perforation 211 corresponds to the first perforation 111. This not only ensures that the first perforation 111 on the first connecting flange 11 and the second perforation 211 on the second connecting flange 21 correspond to each other, but also facilitates the first connecting flange 11 and the second connecting flange 21 to be quickly positioned through the first perforation 111 and the second perforation 211 in the left and right directions during assembly, thereby improving the assembly convenience of the first connecting flange 11 and the second connecting flange 21.

[0036] According to other embodiments of the utility model, at least one first through-hole 111 is arranged on the right side of the first connecting flange 11, and at least one second through-hole 211 is arranged on the right side of the second connecting flange 21, and the second through-hole 211 corresponds to the first through-hole 111. This not only ensures that the first through-hole 111 on the first connecting flange 11 and the second through-hole 211 on the second connecting flange 21 correspond to each other, but also facilitates the first connecting flange 11 and the second connecting flange 21 to be quickly positioned through the first through-hole 111 and the second through-hole 211 in the left and right directions during assembly, thereby improving the assembly convenience of the first connecting flange 11 and the second connecting flange 21.

[0037] Combination Figure 4 As shown, the axle 100 further includes a pad 40, which is detachably disposed between the first connection flange 11 and the second connection flange 21. Specifically, by disposing the pad 40 between the first connection flange 11 and the second connection flange 21, the distance between the first connection flange 11 and the second connection flange 21 can be increased, thereby increasing the distance between the bent tube beam 10 and the steering knuckle 20. In this configuration, the size of the axle 100 can be increased by adding the pad 40 between the first connection flange 11 and the second connection flange 21, thereby realizing the modification of the wheelbase, meeting the user's modification requirements for the vehicle, and thus improving the modifiability of the vehicle.

[0038] Furthermore, the backing plate 40 is provided with a third through-hole 41, which corresponds to the first through-hole 111 and the second through-hole 211 respectively. The fastener 30 sequentially penetrates the first through-hole 111, the third through-hole 41 and the second through-hole 211, and connects and fixes the first connection flange 11, the backing plate 40 and the second connection flange 21. With such a configuration, the backing plate 40 can be added while the structures of the first connection flange 11 and the second connection flange 21 remain unchanged, and the fastener 30 sequentially smoothly penetrates the first through-hole 111, the second through-hole 211 and the third through-hole 41, so that the backing plate 40 can be added without changing the installation of other structures, which not only realizes the modification of the axle 100, but also reduces the modification difficulty and improves the economy of vehicle modification.

[0039] Combination Figure 1-Figure 4 As shown, the first connection flange 11 is provided with a first positioning portion 112, and the second connection flange 21 is provided with a second positioning portion 212. One of the first positioning portion 112 and the second positioning portion 212 is a positioning protrusion, and the other is a positioning hole. The positioning protrusion extends into the positioning hole and is positioned and matched with the positioning hole. Specifically, when the first connection flange 11 and the second connection flange 21 are correspondingly fitted to each other, the first positioning portion 112 on the first connection flange 11 and the second positioning portion 212 on the second connection flange 21 can be positioned and matched, which can not only enable the first connection flange 11 and the second connection flange 21 to be positioned quickly and accurately, which is conducive to saving installation time and reducing production costs, but also can keep the positions of the first connection flange 11 and the second connection flange 21 unchanged after positioning, so that the first connection flange 11 and the second connection flange 21 can be prevented from being misaligned after fitting, thereby improving the installation convenience of the first connection flange 11 and the second connection flange 21, and further improving the assembly convenience of the steering knuckle 20 and the bent tube beam 10.

[0040] Furthermore, the positioning cooperation of the first positioning portion 112 and the second positioning portion 212 is actually the positioning cooperation of the positioning protrusion and the positioning hole. The positioning protrusion has a simple structure and is easy to process on the first connecting flange 11, and the positioning hole has a simple structure and is easy to process on the second connecting flange 21. In addition, the cooperation of the positioning protrusion and the positioning hole can limit the axial direction of the second connecting flange 21 relative to the positioning protrusion and the radial direction of the positioning hole, so that the second connecting flange 21 can be prevented from sliding relative to the first connecting flange 11 after being fitted with the first connecting flange 11, which can improve the connection convenience of the second connecting flange 21 and the first connecting flange 11, thereby improving the assembly convenience of the steering knuckle 20 and the bent tube beam 10. In the embodiment of the utility model, the positioning hole includes but is not limited to a threaded hole.

[0041] Combination Figure 3-Figure 4As shown, the side of the steering knuckle 20 away from the bent tube beam 10 is used to install the brake disc, the thickness of the second connecting flange 21 extends toward the side of the bent tube beam 10, and the second connecting flange 21 and the brake disc are spaced apart. Specifically, when the second connecting flange 21 corresponds to the first connecting flange 11, its thickness extends toward the side of the bent tube beam 10, which not only facilitates the connection and fixation of the second connecting flange 21 with the first connecting flange 11, but also allows the thickness of the second connecting flange 21 to increase the size of the axle 100 between the wheel tracks on both sides of the vehicle, thereby increasing the wheel track of the entire vehicle, which is conducive to improving the stability of the vehicle.

[0042] Furthermore, the side of the steering knuckle 20 away from the bent tube beam 10 is used to install the brake disc, and the second connection flange is arranged to extend toward one side of the bent tube beam 10, so that the second connection flange 21 and the brake disc can be respectively arranged on both sides of the steering knuckle 20. In addition, the second connection flange 21 and the brake disc are spaced apart from each other on the steering knuckle 20. Such an arrangement can, on the one hand, realize flexible disassembly and assembly between the steering knuckle 20 and the bent tube beam 10, and on the other hand, ensure the convenience of assembling the brake disc on the steering knuckle 20.

[0043] Combination Figure 3-Figure 4 As shown, a hub bearing mounting hole 23 is provided on the steering knuckle 20, and a first avoidance groove 213 is provided on a side of the second connecting flange 21 adjacent to the hub bearing mounting hole 23, and the first avoidance groove 213 avoids the hub bearing mounting hole 23. Specifically, the hub bearing mounting hole 23 is provided on the steering knuckle 20 for installing the hub bearing, so as to fix the wheel hub and facilitate the installation of the wheel. The hub bearing mounting hole 23 and the second connecting flange 21 are arranged at intervals on the steering knuckle 20, so as to prevent the second connecting flange 21 from blocking the setting of the hub bearing mounting hole 23. The first avoidance groove 213 is provided on a side of the second connecting flange 21 adjacent to the hub bearing mounting hole 23, and the setting of the first avoidance groove 213 can not only avoid the installation of the hub bearing on the side of the second connecting flange 21 adjacent to the hub bearing mounting hole 23, so as to improve the installation convenience of the hub bearing on the steering knuckle 20, but also ensure that the structural strength of the second connecting flange 21 is suitable for connecting and fixing with the first connecting flange 11, and transmitting power, thereby improving the assembly convenience and structural reliability of the whole vehicle.

[0044] Combination Figure 3-Figure 4 As shown, a brake caliper mounting hole 24 is provided at the upper end of the steering knuckle 20. There are two brake caliper mounting holes 24, and both are spaced apart from the second connecting flange 21. The two brake caliper mounting holes 24 are spaced apart from each other. A second avoidance groove 25 is provided between the two brake caliper mounting holes 24 of the steering knuckle 20. The second avoidance groove 25 is used to avoid the brake caliper.

[0045] Specifically, the steering knuckle 20 can be used to install a brake caliper. A brake caliper mounting hole 24 is provided on the steering knuckle 20, which can provide a connection position for the brake caliper to facilitate the installation of the brake caliper. In the embodiment of the utility model, two brake caliper mounting holes are provided, and both are spaced apart from the second connecting flange 21, which not only facilitates the installation of the brake caliper, but also allows the brake caliper mounting hole 24 to avoid the second connecting flange 21, thereby ensuring the structural strength of the second connecting flange 21, and ensuring the connection reliability of the steering knuckle 20 and the bent tube beam 10.

[0046] Furthermore, the two brake caliper mounting holes 24 are spaced apart from each other to accommodate the mounting structure of the brake caliper. The steering knuckle 20 is provided with a second avoidance groove 25 between the two brake caliper mounting holes 24, so that the brake caliper can be avoided at the position of the steering knuckle 20 corresponding to the two brake caliper mounting holes 24, which not only provides a setting position for the brake caliper in the vehicle, but also makes the space setting of the brake caliper and the steering knuckle 20 more compact, thereby facilitating the reduction of the power transmission loss between the axle 100 and the wheel.

[0047] Combination Figure 1 , Figure 3 and Figure 4 As shown, a knuckle arm 22 is provided at the lower end of the side of the knuckle 20 away from the second connection flange 21. The knuckle arm 22 is used to install a shock absorber. The knuckle arm 22 extends toward one side of the bent tube beam 10 and is bent upward. Specifically, the knuckle arm 22 can provide a setting position for the shock absorber, which can facilitate the connection of the shock absorber with the knuckle 20, and can reduce and filter the transmission of road excitation to the axle 100. The knuckle arm 22 is arranged at the lower end of the second connection flange 21, so that the knuckle arm 22 can avoid the second connection flange 21, which is convenient for the second connection flange 21 to be connected with the first connection flange 11 on the bent tube beam 10. The knuckle arm 22 extends toward one side of the bent tube beam 10 and is bent upward, so that the length of the knuckle arm 22 can be shortened, the distance between the two ends of the knuckle arm 22 in the length direction can be shortened, and the force bearing capacity of the knuckle arm 22 can be improved, thereby improving the structural reliability of the knuckle arm 22.

[0048] Combination Figure 1 , Figure 3 and Figure 4As shown, the steering knuckle arm 22 is tilted toward one side of the second connection flange 21, and the steering knuckle arm 22 is spaced from the first connection flange 11 and the second connection flange 21. Specifically, the steering knuckle arm 22 is tilted toward one side of the second connection flange 21 while being bent upward, which can further improve the force bearing capacity of the steering knuckle 20 and further improve the structural reliability of the steering knuckle arm 22. In addition, the steering knuckle arm 22 and the first connection flange 11 and the first connection flange 11 and the second connection flange 21 are spaced from each other, which can prevent the steering knuckle arm 22 from colliding with the first connection flange 11 and the second connection flange 21 due to being too close, and can prevent the axle 100 of the utility model from making abnormal noises during the driving of the vehicle, and on the other hand, can prevent the steering knuckle arm 22 from contacting the first connection flange 11 or the second connection flange 21, so as to ensure the reliability of the shock absorber, reduce the transmission of road excitation to the axle 100, and further ensure the NVH performance of the whole vehicle.

[0049] Combination Figure 3 and Figure 4 As shown, a sinking reinforcement part 26 is provided between the steering knuckle arm 22 and the steering knuckle 20, and the sinking reinforcement part 26 is provided to be recessed and sunken toward the side away from the bent tube beam 10. Specifically, while the steering knuckle arm 22 is tilted toward the side of the second connecting flange 21, a sinking reinforcement part 26 is provided between the steering knuckle arm 22 and the steering knuckle 20, and the sinking reinforcement part 26 is recessed and sunken toward the side away from the bent tube beam 10, so that a shell structure can be provided on the steering knuckle arm 22, and the opening of the shell structure faces the second connecting flange 21, so as to improve the local force bearing capacity of the steering knuckle arm 22 toward the brake disc side. In this way, the local structural strength between the steering knuckle arm 22 and the steering knuckle 20 can be strengthened, and the stress concentration generated between the steering knuckle arm 22 and the steering knuckle 20 can be resisted, so as to improve the structural reliability of the steering knuckle arm 22.

[0050] According to the embodiment of the utility model, the axle 100 can be applied to a vehicle. By providing the first connection flange 11 on the curved tube beam 10 and opening the first through hole 111 on the first connection flange 11, the existing welding between the steering knuckle 20 and the curved tube beam 10 can be changed to the connection with the fastener 30, thereby realizing the flexible disassembly and assembly of the steering knuckle 20, simplifying the production process of the axle 100, saving processing time, and being conducive to improving the maintenance economy and disassembly and assembly convenience of the axle 100, and being conducive to improving the modifiability of the vehicle.

[0051] In the embodiment of the utility model, a wheel speed sensor mounting hole is also provided on the steering knuckle 20. In practical applications, if the positions of the wheel hub bearing, the wheel speed sensor and the brake caliper on the steering knuckle 20 need to be changed, the steering knuckle 20 can be disassembled by rotating the fastener 30, and then the mounting positions of the wheel hub bearing, the wheel speed sensor and the brake caliper on the steering knuckle 20 can be changed as required, which can not only increase the refitability of the axle 100, but also reduce the refitability difficulty of the axle 100, and improve the maintenance economy of the whole vehicle.
