Abstract

The invention belongs to damping devices, in particular to a secondary buffer damper. The damper comprises an oil storage cylinder and a piston rod, one end of the piston rod is adjusted in the oil storage cylinder; a piston sealing sleeve is arranged on the peripheral surface of the piston rod; the outer peripheral surface of the sealing sleeve is fixed on the inner peripheral surface of the oilstorage cylinder; and the piston sealing sleeve wraps the end, located in the oil storage barrel, of the piston rod. The oil storage cylinder is sleeved with a spring; and the other end of the springis fixed to the area, exposed out of the oil storage cylinder, of the piston rod. An inner spring column is arranged at the bottom of the oil storage cylinder, a blocking sealing piece is arranged atthe other end of the inner spring column, the blocking sealing piece is tightly attached to the inner wall of the oil storage cylinder, a damping oil cavity is formed between the blocking sealing piece and the piston sealing sleeve, and the damping oil cavity is filled with damping oil. The problem that an existing damper is poor in small-amplitude shock effect is solved, and internal damping is achieved through the built-in spring.

Description

technical field [0001] The invention belongs to a shock absorber, in particular to a secondary buffer shock absorber. Background technique [0002] How to make the riders of electric bicycles and motorcycles more comfortable and free from the suffering of bumps and fatigue caused by various reasons of uneven road surface? Today, when electric bicycles and motorcycles are widely used, everyone is concerned about shock absorbers. Higher performance requirements are put forward, and a variety of shock absorber devices have been developed, such as hydraulic shock absorbers, spring shock absorbers, oil-pneumatic spring shock absorbers, spring thread irregular shock absorbers, etc. . But, owing to reasons such as production cost and technology, the shock absorber effect that electric bicycle field has been used is all not ideal now. The structure of the shock absorber is relatively simple, and even there are few structures that a real shock absorber should have inside, so it is ...
