Stable-type damping device

Abstract

The invention discloses a stable-type damping device, which comprises at least two magnets. Opposite magnetic poles of the magnets are adjacent, the magnets are hinged on a cross shear-type expansion bracket, retaining-and-guiding inner sleeves are sleeved outside the magnets, upper end seats and lower end seats are disposed at both ends of the retaining-and-guiding inner sleeves respectively andconnected with both ends of the cross shear-type expansion frame respectively, and damping springs are installed between the upper end seats and the lower end seats. Since opposite magnetic poles of adjacent magnets are arranged oppositely, the closer the distance, the greater the attraction; when severe vibration occurs, the damping springs are compressed and deformed greatly, the elasticity of the damping springs increases linearly with the deformation; when the deformation of the damping springs increases, the distance between adjacent magnets decreases, the attraction increases geometrically, a part of increased elasticity is offset, in other words, impact force to car frames is decreased. By the stable-type damping device, stable damping can be realized when the elasticity of damperscan be kept changing mildly and nonlinearly within a bigger deformation range.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a shock absorber which utilizes magnetic force to achieve stable shock absorption. Background technique [0002] With the rapid development of the automobile industry in recent years, users require not only safety and practicality, but also environmental protection and energy saving. The automobile shock absorber is an important part of the automobile. It is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road. Traditional automobiles use oil-air shock absorbers. When the frame (or body) and the car When the bridges are vibrated and there is relative movement, the piston in the shock absorber is driven to move up and down, so as to achieve the purpose of shock absorption. Due to the aging of the seals, this kind of shock absorber is easy to cause oil leakage and environmental pollution, which violates the concepts of energy saving, ...

AI Technical Summary

Problems solved by technology

This kind of shock absorber can meet the requirements of energy saving and environmental protection, but it cannot meet the safety requirements, because the closer the distance between the two magnets, the greater the repulsive force between them; The distance between the two magnets is relatively large, and the repulsive force is too small relative to the impact force to achieve the purpose of shock absorption; as the distance between the two magnets gets closer, the repulsive force becomes larger, that is to say , The shock absorption force of the shock absorber varies greatly. If this kind of shock absorber is installed on the car, the occupants will feel uncomfortable because the strong vibration cannot be buffered in time.
