Description

Automobile shock absorber
Technical Field
The invention belongs to the technical field of automobile vibration dampers, and particularly relates to an automobile vibration damper.
Background
The working principle of the automobile shock absorber is that when the frame and the axle do reciprocating relative motion and the piston moves reciprocally in the cylinder barrel, the oil in the shock absorber flows reciprocally between two mutually isolated inner cavities through the narrow pore on the valve, and the damping force is formed due to the friction between the pore wall and the oil and the internal friction of liquid molecules, so that the mechanical energy of the vibration of the automobile body is converted into heat energy to be absorbed by the oil and the shell, and then the heat energy is dissipated into the atmosphere. The damping force is related to the cross-sectional area through the oil passage, the valve spring rate, and the viscosity of the oil.
Currently, a passive suspension is a common double-cylinder hydraulic shock absorber, and the damping of the passive suspension is not adjustable, so that the damping characteristic of a suspension system cannot be adjusted according to road conditions, vehicle running conditions or load capacity, and the ideal shock absorbing effect and the operation stability cannot be achieved.
