Background
In an automobile suspension system, since an elastic element (such as a shock absorbing spring) also has a reciprocating motion when filtering road vibration, in order to improve the smoothness of running of an automobile, a shock absorber is usually installed in the suspension system to suppress the vibration of the spring when rebounding after the shock absorption.
The shock absorber adopted in the automotive suspension system is mostly a hydraulic cylinder type shock absorber, and the working principle of the hydraulic cylinder type shock absorber is that when the relative motion occurs between a frame and an axle due to vibration, a piston rod in the shock absorber moves up and down, oil in a cavity of the shock absorber repeatedly flows into the other cavity from one cavity, so that kinetic energy of the relative motion between a piston rod assembly of the shock absorber and a cylinder assembly of the shock absorber is converted into heat energy of the oil to be emitted outwards, and the damping effect is achieved.
The hydraulic cylinder type shock absorber plays a key role in that the aperture of a small hole on the hydraulic cylinder type shock absorber cannot be adjusted, adjustment is difficult to achieve according to the change of road conditions and driving states, under the effect of complex and changeable road surfaces, the hydraulic cylinder type shock absorber cannot be adaptively adjusted according to the intensity of vibration transmitted by the road surfaces, and the instantaneous and changeable oil pressure cannot be adjusted, so that the shock absorber cannot achieve an ideal shock absorption effect, and discomfort is brought to drivers and passengers.
