Embodiment Construction

[0022] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0023] figure 1 It is a schematic diagram of the scheme of the present invention, such as figure 1 As shown, the vehicle suspension of the present invention includes a vehicle body 1, a nut 2, a screw rod 3, a motor 4, a spring 5, a shock absorber 6, a hub 7, and a wheel 12. It is characterized in that: each suspension assembly uses a motor 4 and two screw mechanisms arranged symmetrically; the rotating shaft of the motor 4 is coaxial with the screw rod 3 .

[0024] It is also characterized in that the suspension assembly is arranged in the front and back directions.

[0025] It is also characterized in that each suspension assembly uses two pairs of shock absorbers 6 and springs 5, each pair of shock absorbers 6 and springs 5 ​​are coaxial and axisymmetric, and the upper end is connected to the nut 2 of the screw mechanism with a pin, and the lower e

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.
