Technical Field
The utility model relates to an automobile shock absorber ware technical field especially relates to an automobile shock absorber ware's buffer.
Background
When the frame and the axle reciprocate relative to each other and the piston in the shock absorber also reciprocates in the cylinder, oil in the shock absorber housing repeatedly flows from one chamber to the other chamber through narrow apertures. At the moment, the friction between the hole wall and the oil liquid and the liquid intramolecular friction form damping force to vibration, so that the vibration energy of the vehicle body and the vehicle frame is converted into heat energy, and the heat energy is absorbed by the oil liquid and the shock absorber shell and then is dissipated into the atmosphere to play a shock absorption role. The existing telescopic shock absorber is reset and buffered through a spring, but the spring is easy to damage after being used for a long time, and the existing buffering device is inconvenient to replace the spring.
