Description
Technical Field
The utility model relates to a bumper shock absorber equipment technical field specifically is a bumper shock absorber behind two-way damping.
Background
The shock Absorber (Absorber) is used to suppress the shock when the spring absorbs the shock and then rebounds and the impact from the road surface. The damping device is widely applied to automobiles and is used for accelerating the attenuation of the vibration of a frame and an automobile body so as to improve the driving smoothness of the automobiles. When the automobile passes through an uneven road surface, although the shock absorption spring can filter the vibration of the road surface, the spring can still do reciprocating motion, the shock absorber is used for inhibiting the spring from jumping, the shock absorber is arranged in the suspension system because the elastic element is impacted to generate the shock, in order to improve the running smoothness of the automobile, the shock absorber is arranged in the suspension system and is connected with the elastic element in parallel, in order to attenuate the shock, most of the shock absorbers adopted in the automobile suspension system are hydraulic shock absorbers, the working principle is that when the frame (or the automobile body) and the axle vibrate and the relative motion occurs, a piston in the shock absorber moves up and down, and the oil in the 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. The damping force increases and decreases with the relative movement speed between the vehicle frame and the axle (or wheel) when the oil passage section and the like are constant, and is related to the viscosity of oil, and a bidirectional damping rear shock absorber is one of the shock absorbers.
The existing two-way damping rear shock absorber on the market can be loosened from the connection between the two-way damping rear shock absorber and the underframe in the process of long-term use, so that the lower sleeve can be separated.
