Problems solved by technology

At present, ordinary double-tube hydraulic shock absorbers are usually used as passive shock absorbers. Since their damping cannot be adjusted, they cannot adapt to changing driving conditions and arbitrary road excitations, and cannot achieve ideal shock absorption effects and handling stability.

Abstract

The invention relates to a novel damping adjustable shock absorber, and the internal throttling structure of the novel damping adjustable shock absorber is adjusted through a motor. The novel damping adjustable shock absorber comprises a bottom valve assembly, a piston valve assembly, an oil storage cylinder, a working cylinder, a sleeve, a piston rod, a guide block, an upper hanging ring and a close over, and is characterized by also comprising a damping adjusting valve block, a transmission mechanism and a motor, wherein a leakage groove is arranged in the damping adjusting valve block; an orifice is arranged in the piston rod and is matched with the damping adjusting valve block to form an adjustable orifice; the motor is fixedly connected with the upper hanging ring; the motor is connected with the sleeve through the transmission mechanism and drives the sleeve to rotate; the sleeve is connected with the damping adjusting valve block through a shifting fork on the sleeve; the sleeve drives the damping adjusting valve block to rotate, so that the damping adjusting valve block rotates relative to the piston rod, the opening degree of the adjustable orifice is changed, and the adjustment of the damping force is achieved.

Description

technical field [0001] The invention relates to a vehicle component, specifically a damping adjustable shock absorber which uses a motor to adjust the internal throttling structure. The shock absorber can change the damping of the suspension according to the actual road conditions when the vehicle is running, thereby realizing Vehicles have dual requirements for ride comfort and safety. Background technique [0002] Shock absorber is an important part of the car, and its performance directly affects the comfort, handling stability and safety of the car. At present, the passive shock absorber usually adopts ordinary twin-tube hydraulic shock absorber. Since its damping is not adjustable, it cannot adapt to changing driving conditions and arbitrary road excitations, and cannot achieve ideal shock absorption effect and handling stability. In order to improve the ride comfort and handling stability of automobiles, the study of damping adjustable shock absorbers is of great sign...
