Intelligent variable damping shock absorption system of commercial vehicle and shock absorber of intelligent variable damping shock absorption system

Abstract

The invention relates to the field of commercial vehicle hanging, in particular to a variable damping shock absorption system and a shock absorber of the variable damping shock absorption system. The intelligent variable damping shock absorption system of a commercial vehicle comprises a control unit and a space sensor which are fixedly installed on a vehicle body. The control unit obtains wheel speed signals through a wheel speed signal harness. Output signals of the space sensor are collected by the control unit through a space sensor harness. The control unit is connected with the shock absorber in a controlled mode through a shock absorber damping control harness and the effective hole diameter of a small liquid-passing hole of the shock absorber is adjusted. The shock absorber comprises a steering engine and a baffle. The steering engine is fixedly installed on a piston. One end of the baffle is fixedly connected with the output end of the steering engine and the other end of the baffle is matched with the small liquid-passing hole formed in the piston. The steering engine drives the baffle to rotate to change the effective hole diameter of the small liquid-passing hole. According to the variable damping shock absorption system and the shock absorber, the load of the vehicle is calculated, the damping force of the shock absorber is adjusted according to the load, so that the damping force is matched with the load condition of the vehicle, and therefore the riding comfort for a passenger in the vehicle is improved.

Description

technical field [0001] The invention relates to the field of commercial vehicle suspension, in particular to a variable damping shock absorption system and a shock absorber thereof. Background technique [0002] Shock absorbers are installed between the longitudinal beams and the suspension of commercial vehicles to buffer vibrations. The buffering effect is related to the damping force; The design value will be relatively large, so that when the commercial vehicle is not carrying cargo or when there are few passengers in this design, the damping force will not match the actual load, resulting in poor comfort. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a commercial vehicle intelligent variable damping shock absorber and its shock absorber. By measuring the change in the distance between the suspension and the longitudinal beam of the vehicle body, the load of the vehicle is calculated, and then the shock abs...
