Description

Shock absorber device with limiting effect

Technical Field

The utility model relates to a bumper shock absorber technical field specifically is a bumper shock absorber device with limiting displacement.

Background

The shock absorber is divided into two types, mainly hydraulic and pneumatic, from the point of view of the damping-producing material, and also a variable damping shock absorber. The shock absorber is mainly used for inhibiting the shock when the spring absorbs the shock and rebounds and the impact from the road surface. When the shock absorber passes through the uneven road surface, although the shock absorbing spring can filter the shock of the road surface, the spring can still reciprocate, and the shock absorber is used for inhibiting the spring from jumping. The shock absorber is too soft, the vehicle body jumps up and down, and the shock absorber is too hard, so that too much resistance is brought, and the normal work of the spring is hindered. In a retrofit process for a suspension system, a stiff damper is used in conjunction with a stiff spring, which stiffness is related to vehicle weight, so that heavier vehicles typically use stiffer dampers. The device connected with the vibration inducing crankshaft is used for resisting the torsional vibration of the crankshaft (namely the phenomenon that the crankshaft is twisted by the impact force of cylinder ignition).

The existing shock absorber device with the limiting function is troublesome in mounting and dismounting the spring and inconvenient to use. Therefore, we propose a shock absorber device with a limiting function.
