Description

Electromagnetic damping type automobile shock absorber

Background

The main function of the shock absorber is to alleviate and attenuate the vibration and impact encountered by the vehicle in the driving process, ensure the comfort, stability and safety of the rider, further improve the stability and service life of the vehicle, and mainly inhibit the vibration and impact from the road surface when the spring rebounds after absorbing shock. When the shock absorber passes through the uneven road surface, although the shock absorbing spring can filter the shock of the road surface, the spring can still reciprocate, and the shock absorber is used for inhibiting the spring from jumping. The shock absorber is too soft, the automobile body jumps up and down, too large resistance can be brought by the shock absorber too hard, the normal work of the spring is prevented, the shock is generated due to the fact that the elastic element is impacted in a suspension system, in order to improve the running smoothness of an automobile, the shock absorber is installed in the suspension in parallel with the elastic element, in order to attenuate the shock, most of shock absorbers adopted in the automobile suspension system are hydraulic shock absorbers, the working principle is that when the automobile frame (or the automobile body) and an axle vibrate and the relative motion occurs, a piston in the shock absorber moves up and down, and oil in a shock absorber cavity repeatedly flows into the other cavity from one cavity through different pores. At the moment, the friction between the hole wall and the oil and the internal friction between oil molecules form damping force on vibration, so that the vibration energy of the automobile is converted into oil heat energy, and then the oil heat energy is absorbed by the shock absorber and is emitted into the atmosphere. When the cross section and other factors of the oil passage are not changed, the damping force is increased and decreased along with the relative movement speed between the vehicle frame and the vehicle axle (or the vehicle wheel) and is related to the viscosity of the oil.

The existing shock absorbers are various in types, including air pressure, hydraulic pressure, springs and the like, but when the shock absorbers are used, the damping of the shock absorbers cannot be adjusted along with the weight of a vehicle body, so that when the shock absorbers are used specifically, when the gravity is too large, the shock absorbers are damaged, the shock absorption effect is poor, and the shock absorption system of a vehicle is influenced.
