Description

Damping spring device for simulation scale-down racing car

Technical Field

The utility model relates to a simulation scale cycle racing damping spring ware that reduces belongs to damping spring ware technical field.

Background

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. During the retrofit process for suspension systems, the stiff shock absorbers are to be mated with stiff springs; the stiffness of the spring is, in turn, related to the weight of the vehicle, so that heavier vehicles typically employ 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), and the vibration absorbing spring device is used for absorbing vibration. Various shock absorbing spring mounts are also often seen on simulated downscaled cars to allow the car to run smoothly.

The existing spring shock absorber usually absorbs shock through a spring, when the shock amplitude is large, shock absorption can not be well performed through the spring, when the spring breaks down, the whole shock absorber is difficult to play a shock absorption role again, and needs to be maintained and replaced, which is troublesome.
