Abstract

The invention discloses a vehicle suspension, comprising upper cross arms 10, lower cross arms 11, hubs 7, springs 5, shock absorbers 6, a wheel 12 and other conventional spare parts. The vehicle suspension is characterized in that the suspension comprises a motor 4 and screw structures which are symmetrically arranged; the axis of rotation of the motor 4 is coaxial with screws 3 of the screw structures; and the screws 3 are driven to rotate by the motor 4. By starting the motor 4 to drive the screws 3 to rotate to change the front and back positions of nuts 2, the aims of adjusting the ground clearance of the vehicle and changing the stiffness coefficients of the springs in the vertical direction and the damping coefficients of the shock absorbers 6 in the vertical direction can be achieved, so that the vehicle adapts to the requirement of ride performance of travelling on different pavements at different speeds. Besides, the motionless posture of the vehicle can be adjusted by changing the height of the single suspension.

Description

【Technical field】 [0001] The invention relates to a vehicle suspension device, in particular, the invention relates to a semi-active vehicle suspension with the functions of adjusting the height of the vehicle from the ground and damping vibration. 【Background technique】 [0002] The current semi-active suspension of vehicles generally achieves the purpose of reducing vehicle vibration by adjusting the damping coefficient of the shock absorber to change the vibration characteristics of the vehicle suspension device. And the damping effect is limited. Especially for large-tonnage military vehicles, if the damping coefficient is changed, the damping force of the entire vehicle shock absorber may be reduced, so that when the vehicle is driving on a high-frequency gravel road, the temperature of the shock absorber rises rapidly and thus It makes the vehicle's vibration damping performance worse, but it has a bad effect. [0003] The present invention is proposed aiming at the ...
