Description

Technical Field

[0001] The present application belongs to the technical field of vehicle manufacturing, and in particular relates to a steering assembly and a vehicle. Background Art

[0002] Since new energy vehicles generally use electric drive systems, traditional hydraulic power-assisted rack and pinion steering systems may not be suitable. Therefore, the corner module, as an electronic power steering system, has been widely used in new energy vehicles. It uses electronic sensors and electric power steering mechanisms to apply appropriate force to the steering through the control unit, thereby achieving more precise and flexible steering control.

[0003] The corner module is driven by an independent steering motor. There is no mechanical connection between the left and right wheels like the traditional steering rack and steering rod, so the horizontal force cannot be balanced, which makes it difficult for the internal gear mechanism of the steering motor to have close contact and there is a meshing gap.

[0004] The vehicle is disturbed by external vibrations during driving. Due to the lack of sufficient damping force to suppress the shimmy, an excessive amplitude is generated, which aggravates the gear wear of the internal gear mechanism of the steering motor. The wear of the gears will increase the meshing clearance and further aggravate the shimmy, reduce the service life and affect the driving stability and comfort. Utility Model Content

[0035] Figure 1 This is a partial exploded schematic diagram of a steering assembly provided according to one embodiment of the present application. Figure 2 for Figure 1Partial exploded view of the steering assembly from another perspective. Figure 1 and Figure 2 The steering assembly includes a shock absorber 100 and a vehicle corner module 200. The vehicle corner module 200 includes a bogie 210. The shock absorber 100 is disposed below the bogie 210 and can be connected between the bogie 210 and a vehicle frame (the frame is not shown in the figure). The shock absorber 100 is configured to be able to unidirectionally telescopically move to provide a damping force between the bogie 210 and the frame.

[0036] In this embodiment, the vehicle corner module 200 is a modular vehicle component that integrates wheels, suspension, drive unit and brake unit and has a steering function. The vehicle corner module 200 is widely used in new energy vehicles such as electric vehicles and hybrid vehicles.

[0037] The bogie 210 in the vehicle corner module 200 is a main load-bearing component, providing support for other components in the vehicle corner module 200, such as a steering motor, a shock absorber, etc., which are connected to the bogie 210. In a specific application, the bogie 210 is generally made of a metal material with high strength and good rigidity to withstand various forces and torques generated when the vehicle is running.

[0038] It should be noted that in Figure 1 and Figure 2 The vehicle corner module 200 in the illustrated embodiment hides some components, such as a steering motor and the like.

[0039] The shock absorber 100 is disposed below the bogie 210 , and the bogie 210 and the shock absorber 100 are staggered in the up-down direction, so as to avoid interference during the steering process.

[0040] It should be understood that when a vehicle equipped with the steering assembly is turning, the shock absorber 100 can undergo unidirectional telescopic movement, and the damping force provided will be changed accordingly to adapt to the driving conditions of the vehicle. This can attenuate the vibration transmission between the bogie 210 and the frame, reduce the steering shock caused by uneven road surface, and reduce the swing amplitude.

[0041] In addition, the shock absorber 100 maintains a compressed state, so that a unidirectional load can always be applied to the bogie 210, so that the gears of the gear mechanism in the steering motor installed on the bogie 210 maintain close contact, reducing gear wear and ensuring the service life of the vehicle corner module 200.

[0042] It can be seen that the steering assembly provided by the present application is additionally provided with a shock absorber 100 on the basis of the vehicle corner module 200, and the shock absorber 100 can provide a damping force to attenuate the vibration transmission between the bogie 210 and the frame, and reduce the vehicle shimmy. In addition, the shock absorber 100 can also provide a certain degree of pre-pressure to the steering motor in the vehicle corner module 200 through the bogie 210 to ensure that the gears in the steering motor maintain a close contact state, reduce gear wear, reduce the risk of aggravated shimmy due to gear wear, and increase the service life of the vehicle corner module 200.

[0043] It should be noted that the above-mentioned vehicle frame generally refers to a sub-frame, and the gear mechanism in the above-mentioned steering motor generally refers to a reduction mechanism inside the steering motor.

[0044] In a further optional embodiment, the steering assembly further includes a lower control arm 300 , and the lower control arm 300 is connected between the bogie 210 and the vehicle frame. One end of the shock absorber 100 is connected to the bogie 210 , and the other end of the shock absorber 100 is connected to the lower control arm 300 .

[0045] In this embodiment, the shock absorber 100 is connected to the vehicle frame through the lower control arm 300 . In other words, the shock absorber 100 is not directly fixed on the vehicle frame, but is indirectly connected to the vehicle frame through the lower control arm 300 .

[0046] It should be understood that the lower control arm 300 is connected to the steering rack 210 in the vehicle corner module 200 , and the lower control arm 300 can be used to constrain the vehicle corner module 200 .

[0047] It should be noted that, in another optional embodiment, the end of the shock absorber 100 away from the bogie 210 can be directly connected to the frame. In comparison, the layout scheme of the shock absorber 100 using this embodiment requires an additional mounting position on the frame for mounting one end of the shock absorber 100.

[0048] In a further optional embodiment, the bogie 210 is provided with a first mounting structure 211 and a second mounting structure 212 , and both the first mounting structure 211 and the second mounting structure 212 are located at the bottom end of the bogie 210 .

[0049] The first mounting structure 211 is hinged to the lower control arm 300 , and the second mounting structure 212 is hinged to one end of the shock absorber 100 .

[0050] In this embodiment, the first mounting structure 211 on the bogie 210 is used to mount the lower control arm 300, and the second mounting structure 212 on the bogie 210 is used to mount the shock absorber 100. The first mounting structure 211 and the second mounting structure 212 are respectively hinged to the lower control arm 300 and the shock absorber 100, that is, the lower control arm 300 and the shock absorber 100 are both movably connected, and during the operation of the vehicle, it is ensured that the lower control arm 300 and the shock absorber 100 have a certain degree of freedom of movement.

[0053] In this embodiment, the piston rod assembly 13 is movably connected to the sleeve 170, one end of the piston rod assembly 13 is arranged in the sleeve 170, and the other end of the piston rod assembly 13 extends outside the sleeve 170. The piston rod assembly 13 can move axially relative to the sleeve 170, thereby changing the damping force.

[0054] The end of the piston rod assembly 13 extending outside the sleeve 170 is the end away from the sleeve 170 and is hinged to the second mounting structure 212 . The end of the sleeve 170 away from the piston rod assembly 13 is connected to the lower control arm 300 .

[0055] In a specific application, the shock absorber 100 is a single-tube inflatable structure, that is, the sleeve 170 is filled with gas, and the piston rod assembly 13 can change the volume of the gas in the sleeve 170 during the axial telescopic movement. Accordingly, the air pressure in the sleeve 170 changes, resulting in a change in the damping force provided.

[0056] Of course, the shock absorber 100 is not limited to a single-tube inflatable structure. For example, a compression spring is provided in the sleeve 170 , and the compression spring changes the compression length under the action of the piston rod assembly 13 , thereby changing the damping force provided.

[0057] In some optional embodiments, the shock absorber 100 further includes a ball head assembly 11 and an inner bushing assembly 12. The ball head assembly 11 is disposed at one end of the piston rod assembly 13 away from the sleeve 170 and is hinged to the bogie 210. The inner bushing assembly 12 is disposed at one end of the sleeve 170 away from the piston rod assembly 13 and is hinged to the lower control arm 300.

In other words, the shock absorber 100 is movably connected to the bogie 210 and the lower control arm 300, and such a setting is mainly to ensure that the shock absorber 100 has a certain degree of freedom of movement during the driving process of the vehicle.

Figure 4 In some optional embodiments, the piston rod assembly 13 includes a threaded rod 130 , a locking nut 140 , a piston rod mounting seat 150 and a piston rod 160 which are sequentially connected along the axial direction of the sleeve 170 .
