Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a candle-type suspension angle module structure and a vehicle. Background Art

[0002] The candle-style suspension corner module structure refers to an integrated module assembly that integrates drive, braking, suspension, and steering functions. Because this module assembly is located at the corresponding positions of the vehicle's four wheels, it is called a corner module. The corner module facilitates the vehicle's four-wheel steering and lateral form functions. The corner modules on the vehicle utilize a distributed drive system, with multi-wheel drive being redundant and providing high safety. In existing corner modules, although the overall suspension structure is a candle-style structure, the use of upper and lower swing arms as the degrees of freedom for the vertical movement of the wheels results in lateral displacement and occupies a large amount of lateral space.

[0003] Therefore, there is an urgent need for a candle-type suspension angle module structure and a vehicle to solve the technical problem of lateral displacement of the wheels. Summary of the Invention

[0033] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0034] like Figure 1 and Figure 2As shown, this embodiment provides a candle-type suspension angle module structure, which includes a suspension structure, a steering mechanism 5, a drive mechanism 6 and a brake mechanism 7. The suspension structure is used to connect the wheels 8 and the lower body of the vehicle. The suspension structure includes a steering arm 1, a slide rail mechanism 2 and a steering knuckle 3. The slide rail mechanism 2 is installed on one side of the steering arm 1 in the vertical direction, and the steering knuckle 3 is slidably arranged on one side of the steering arm 1 in the vertical direction, and one end of the steering knuckle 3 is fixedly connected to the slide rail mechanism 2, and the other end of the steering knuckle 3 is transmission-connected to the wheel 8; the steering mechanism 5 is transmission-connected to the steering arm 1, and is used to drive the steering arm 1 to rotate around the vertical axis; the drive mechanism 6 is arranged at the end of the steering knuckle 3 away from the slide rail mechanism 2, and the drive mechanism 6 is transmission-connected to the wheel 8; the brake mechanism 7 is arranged at the end of the steering knuckle 3 away from the slide rail mechanism 2, and is used to brake the wheel 8.

[0035] Specifically, since the slide rail mechanism 2 is installed on one side of the steering arm 1 in the vertical direction and the steering knuckle 3 is slidably arranged in the vertical direction, and the steering knuckle 3 is fixedly connected to the wheel 8 and the slide rail mechanism 2 respectively, when the wheel 8 travels on a bumpy road, the wheel 8 can drive the steering knuckle 3 to move in the vertical direction, ensuring the freedom of the wheel 8 in the vertical direction; and the steering knuckle 3 is fixedly connected to the slide rail mechanism 2, and the movement of the steering knuckle 3 in the lateral direction, that is, the horizontal plane direction, is restricted. Therefore, the horizontal distance between the wheel 8 and the steering arm 1 is limited, that is, the wheel 8 will not produce lateral displacement, reducing the lateral space occupied, which can effectively reduce the space requirement of the candle-type suspension angle module structure, thereby meeting the 360° steering of the wheel 8 and achieving the goal of reducing the restrictions of the candle-type suspension angle module structure on vehicle design; the wheel 8 forms an integral whole with the steering arm 1 and is driven by the steering mechanism 5. The wheel 8 and the steering arm 1 rotate around the vertical axis and can achieve 360° rotation, thereby realizing the vehicle's lateral driving, oblique driving and in-place steering functions.

[0036] Specifically, the slide rail mechanism 2 includes a slide rail 21 and a slider 22. The slide rail 21 is fixedly installed on one side of the steering arm 1 in the vertical direction, and the slider 22 is slidably installed on the slide rail 21 in the vertical direction; one end of the steering knuckle 3 is fixedly connected to the slider 22, and the other end of the steering knuckle 3 is transmission connected to the wheel 8.

[0037] Specifically, since the slider 22 is installed on the slide rail 21 for sliding in the vertical direction, and the steering knuckle 3 is fixedly connected to the wheel 8 and the slider 22 respectively, the wheel 8 can drive the steering knuckle 3 and the slider 22 to move in the vertical direction, thereby ensuring the freedom of the wheel 8 in the vertical direction; and the slider 22 slides in cooperation with the slide rail 21, and the movement of the slider 22 in the lateral direction, that is, the horizontal plane direction, is restricted, so the horizontal distance between the wheel 8 and the steering arm 1 is limited, that is, the wheel 8 will not produce lateral displacement, reducing the lateral occupied space, and the slide rail 21 arranged in the vertical direction plays a guiding role. The slider 22 is used in cooperation with the slide rail 21, the structure is simple, and the space occupied by the components is small, which can effectively reduce the space demand of the candle-type suspension angle module structure, thereby meeting the 360° steering of the wheel 8 and achieving the goal of reducing the restriction of the movement envelope of the candle-type suspension angle module structure on the vehicle design.

[0038] Optionally, the suspension structure further includes a damping mechanism 4, one end of which is fixedly connected to the steering arm 1, and the other end of which is fixedly connected to the steering knuckle 3, and the damping mechanism 4 is arranged in the vertical direction. In this embodiment, the damping mechanism 4 is arranged in the vertical direction, which can improve the smoothness of the movement of the wheel 8 in the vertical direction and limit the lateral displacement of the wheel 8, thereby improving the lateral rigidity. The damping mechanism 4 adopts the damping spring slide assembly in the prior art. The specific structure and working principle are not described in detail in this embodiment. The damping mechanism 4 can cooperate with the steering knuckle 3 and the slide rail mechanism 2 to realize the up and down jumping of the wheel 8 relative to the steering arm 1, transmit the vertical load, and absorb the vertical vibration of the wheel 8.

[0039] Optionally, the steering arm 1 includes a transverse section 11 and a vertical section 12. The transverse section 11 extends horizontally, the vertical section 12 extends vertically, the slide rail mechanism 2 is mounted on the vertical section 12, the upper end of the vibration damping mechanism 4 is fixedly connected to the transverse section 11, the steering knuckle 3 is arranged horizontally, and the lower end of the vibration damping mechanism 4 is fixedly connected to the steering knuckle 3. The transverse section 11 and the steering knuckle 3 are located on the same vertical plane, and the transverse section 11 and the steering knuckle 3 extend in the same direction, so that the vibration damping mechanism 4 can be arranged in the vertical direction. The vertical section 12 and the vibration damping mechanism 4 are both arranged in the vertical direction, so that the vertical support strength can be improved. The vehicle is arranged on the same side of the transverse section 11 and the steering knuckle 3. Specifically, the vibration damping mechanism 4, the slide rail mechanism 2, the steering knuckle 3, and the wheel 8 are arranged below the transverse section 11. The structure is compact, the occupied space is reduced, and it is suitable for vehicles with small dimensions.

[0040] Optionally, the steering arm 1 further includes a bent section 13, one end of which is connected to the transverse section 11 and the other end of which is connected to the vertical section 12. The bent section 13 is configured as a curved structure. The bent section 13, which connects the transverse section 11 and the vertical section 12 with a curved structure, improves the support toughness of the steering arm 1 and ensures that the steering arm 1 can withstand strong vertical impact loads.

The reducer assembly 52 is used to drive the steering arm 1 to rotate about a vertical axis. The transmission between the steering motor 51 and the reducer assembly 52 is continuous, and the reducer assembly 52 can drive the steering arm 1 and the wheel 8 to achieve 360° rotation.

[0042] Optionally, the output end of the speed reducer assembly 52 is in transmission connection with the transverse section 11 of the steering arm 1. In this embodiment, the speed reducer assembly 52, steering motor 51, transverse section 11, vibration damping mechanism 4, steering knuckle 3, wheel 8, drive mechanism 6, and brake mechanism 7 are all arranged on the same side of the vertical section 12 to reduce space occupation.
