Description

Technical Field

[0001] The utility model relates to the technical field of automobile assembly, in particular to a shock absorber fastening device. Background Art

[0002] The shock absorber is a device used to suppress the shock caused by the rebound of the spring after absorbing the shock and the impact from the road surface. The shock absorber assembly consists of the shock absorber, lower spring pad, dust cover, spring, shock pad, upper spring pad, spring seat, bearing, top rubber, and nut. The inside of the shock absorber is filled with oil. There is one or more holes on the piston head of the shock absorber. When the shock absorber moves up and down, the oil in the cavity flows back and forth between the upper and lower chambers through the small holes on the piston head. Because the oil is viscous, it also releases a lot of heat, which is equivalent to converting the kinetic energy generated by the vehicle's bumps into heat energy.
