Description
Technical field
The utility model relates to vapour and to rub accessory technical field, is specially a kind of rear shock absorber.
Background technique
Concussion when vibration damper rebounds after being mainly used to suppress spring shock-absorbing and the impact from road surface.Through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is just used to suppress this spring to jump.Vibration damper is too soft, and vehicle body will vertical bounce, and vibration damper will bring too large resistance too firmly, hinders spring normally to work.About in the retrofit process of suspension system, hard vibration damper will be arranged in pairs or groups mutually with hard spring, and the hardness of spring is closely bound up with car weight, and therefore heavier car generally adopts harder vibration damper.
Traditional shock absorber is when bearing external force, and the head and the tail two ends of spring, with fixed base and Mobile base, relative bounce-back often occur, and the head and the tail two ends of spring and fixed base and Mobile base produce and slide, and local deformation occurs spring, causes rear shock absorber to be scrapped.
Spring in traditional shock absorber is when bearing external force, easily bending in the radial direction of spring, and then the center line causing the center line of piston rod and damper is not on the same line, makes piston rod in piston rod and damper sliding process easily occur the phenomenon of being out of shape.
