Abstract
The utility mode provides a buffer system of a shock absorber, which comprises a buffer piston (1), the buffer piston (1) is sheathed on a piston rod (2) on the shock absorber, one side of the piston rod (2) is extended into a damping cylinder (3) of the shock absorber, the buffer piston (1) and the damping cylinder (3) are arranged in a front breeches pipe (4) of the shock absorber, the buffer piston (1) is connected with the piston rod (2) in a floating way, the buffer piston (1) is provided with two symmetrical pressure release holes (5), the pressure release holes (5) are arranged along the axial direction of the buffer piston (1) to be parallel with the piston rod (2), one side of the buffer piston (1), which is directed to the damping cylinder (3), is cone-shaped, and movement oil in the damping cylinder (3) flows into the front breeches pipe (4) by the pressure release valves (5) when the buffer piston (1) moves into the damping cylinder (3) along with the movement of the piston rod (2). With the buffer system, the buffering effect of the shock absorber can be improved, the phenomenon that the system is hauled when the system is buffered and restored is eliminated, and the riding comfortableness of the shock absorber is improved.
Description
Technical field
The utility model relates to a kind of buffer system of vibration damper.
Background technique
The slit extruding back of the motion oil of vibration damper between cushion collar and damped cylinder forms the buffering resistance at present, between cushion collar and cylinder body, produce vacuum like this, thereby cause cushion collar when the disengaging damped cylinder slides, to be easy to generate the sensation that pulls, the travelling comfort that influence is ridden.
Summary of the invention
The utility model provides a kind of buffer system of vibration damper, and it can improve the cushioning effect of vibration damper, eliminates and cushions phenomenon to be pulled when resetting, and improves the travelling comfort of the rider of vibration damper.
The utility model has adopted following technological scheme: a kind of buffer system of vibration damper, it comprises cushion plugs, cushion plugs is enclosed within on the piston rod of vibration damper, one side of piston rod stretches in the damped cylinder of vibration damper, cushion plugs and damped cylinder are positioned at the front fork tube of vibration damper, described cushion plugs is connected for floating with piston rod, on cushion plugs, have the relief hole of two symmetries, relief hole is positioned at the axially parallel with piston rod of cushion plugs, a side of pointing to damped cylinder in cushion plugs is set to taper, when cushion plugs along with the moving in the damped cylinder of piston rod, the motion oil in the damped cylinder flows in the front fork tube by relief hole.
Described cushion plugs is aluminium or PVC material.Described relief hole is a strip hole.
The utlity model has following beneficial effect: the utility model is provided with relief hole on cushion plugs, can eliminate between cushion collar and the cylinder body like this and produce vacuum pressure, prevent that the phenomenon that damped cylinder pulls from appearring in cushion collar, make cushion collar along with piston rod slides smooth and easy in damped cylinder, smoother when resetting, the rider travelling comfort is effective.Cushion plugs of the present utility model is aluminium or PVC material, and aluminium and PVC material are lightweight material, so not only is beneficial to floating of cushion plugs, and the good stability when using.
Description of drawings
View when Fig. 1 moves with piston rod for cushion plugs of the present utility model
Embodiment
In Fig. 1, the utility model is a kind of buffer system of vibration damper, it comprises cushion plugs 1, cushion plugs 1 is aluminium or PVC material, cushion plugs 1 is enclosed within on the piston rod 2 of vibration damper, one side of piston rod 2 stretches in the damped cylinder 3 of vibration damper, cushion plugs 1 and damped cylinder 3 are positioned at the front fork tube 4 of vibration damper, cushion plugs 1 is connected for floating with piston rod 2, on cushion plugs 1, have the relief hole 5 of two symmetries, relief hole 5 is a strip hole, relief hole 5 is positioned at the axially parallel with piston rod 2 of cushion plugs 1, a side of pointing to damped cylinder 3 in cushion plugs 1 is set to taper, when cushion plugs 1 along with the moving in the damped cylinder 3 of piston rod 2, the motion oil in the damped cylinder 3 flows in the front fork tubes 4 by relief holes 5.When vibration damper restored, relief hole 5 can be eliminated fast between cushion plugs 1 and the damped cylinder 3 and produce vacuum pressure, and the vacuum space in the damped cylinder 3 is communicated with atmosphere rapidly, eliminated vacuum pressure.
Claims (3)
