Spring and electromagnetism assist damping device

Abstract

The invention provides a spring and electromagnetism assist damping device. The spring and electromagnetism assist damping device comprises an upper shell, a lower shell, a circuit box, a supporting device, an energized solenoid and a support, wherein the upper shell can move upwards or downwards relative to the lower shell, the circuit box comprises a variable resistor and a power source, the circuit box is connected with the supporting device and the energized solenoid respectively, and the supporting device comprises a pressure plate, a magnet and a spring. A clamping groove welded to the pressure plate can drive a sliding block on a slide rheostat to move at the same time. Because of movement of the sliding block on the slide rheostat, resistance of the slide rheostat changes so as tochange the electric current in a circuit, the magnetic field intensity of the energized solenoid is changed then, the magnitude of magnetic field repulsive force between the energized solenoid and thedisk-shaped magnet is changed, and the spiral spring is assisted with damping. Leakproofness of the whole spring and electromagnetism assist damping device is kept, a damping effect is enhanced, andthe service life of the damping spring is prolonged. The spring and electromagnetism assist damping device has the advantages of being simple in structure, automatic in damping adjustment and applicable to various shock occasions.

Description

technical field [0001] The invention relates to the technical field of automobile shock absorption, in particular to a spring-electromagnetic auxiliary shock absorption device. Background technique [0002] The traditional automobile shock absorber has a limited shock absorption range. When encountering a relatively large vibration shock, the shock absorber cannot have an ideal shock absorption effect. Moreover, if a large impact force acts on the shock absorber for a long time, the life of the shock absorber will be greatly reduced, and the shock absorption effect will tend to deteriorate, which will not only affect the comfort of the car, but also affect the quality of the car. Part life. In addition, conventional shock absorbers cannot adjust the damping, so that the range of applications of such shock absorbers is limited. Contents of the invention [0003] The present invention aims at the deficiencies in the above-mentioned prior art, and proposes a spring-electrom...
