Abstract
The invention discloses a cushioning device for an inverted front shock absorber, which comprises a piston rod (1) and a damping cylinder (2), wherein the piston rod (1) and the damping cylinder (2) are positioned in a shock absorbing bushing of a shock absorber; the piston rod (1) extends into the damping cylinder (2); and a bumping block (3) is sleeved on the piston rod (1). The cushioning device has the characteristics that: the tail part of the damping cylinder (2) is provided with an extension body (4); the bumping block (3) extends into the extension body (4) along with the piston rod (1) and moves up and down; the extension body (4) is provided with a plurality of discharge orifices (5) which are distributed along the moving direction of the bumping block (3); the bumping block (3) extrudes hydraulic oil in the extension body (4) to force the hydraulic oil to be discharged through the discharge orifices (5) to form hydraulic buffering force. The cushioning device not only can improve the buffering performance and avoid the phenomenon of running down, but also can realize graded buffering, and has good buffering effect.
Description
Technical field
The present invention relates to a kind of damping device of inverted front shock absorber
Background technique
Originally the buffer stopper on the inverted front shock absorber piston rod adopts oil resistant rubber, because oil resistant rubber is stable bad, phenomenons such as latex and fatigue appear easily, pooling feature descends, when latex or fatigue occurring, piston rod continues the descending phenomenon that just is easy to occur hitting the end, and the cost of oil resistant rubber is than higher in addition.
Summary of the invention
The present invention relates to a kind of damping device of inverted front shock absorber, it not only improves the performance of buffering, prevents the phenomenon of hitting the end, and can realize classification buffering, good buffer effect.
The present invention has adopted following technological scheme: a kind of damping device of inverted front shock absorber, it comprises piston rod and damped cylinder, piston rod and damped cylinder are positioned at the damping sleeve pipe of vibration damper, piston rod stretches in the damped cylinder, at upper cover of piston rod buffer stopper is arranged, described damped cylinder afterbody is provided with extension body, buffer stopper moves up and down along with piston rod stretches in the extension body, on extension body, be distributed with some discharge orifices, discharge orifice distributes along the direction that buffer stopper moves, hydraulic oil in the buffer stopper extruding extension body forces hydraulic oil to carry out earial drainage by discharge orifice, constitutes hydraulic cushion power.
Described buffer stopper is the PVC material.Described discharge orifice is descending distribution, and in the bottom and the close discharge orifice aperture maximum of buffer stopper of extension body, what the aperture of remaining discharge orifice made progress along the bottom of extension body diminishes gradually.
The present invention has following beneficial effect: the bottom of damped cylinder is provided with extension body among the present invention, buffer stopper can move up and down along with piston rod stretches in the extension body, in the time of in buffer stopper stretches into extension body, hydraulic oil is closed in the clutch release slave cylinder, hydraulic oil carries out the classification earial drainage by the discharge orifice that differs in size then, thereby reach the function of buffering, smoother when so not only cushioning, good buffer effect, and the performance of raising buffering, can prevent that the phenomenon of hitting the end from occurring, differing in size of discharge orifice can be realized the classification earial drainage simultaneously.The buffer stopper that the present invention adopts is the PVC material, and the PVC material is not only corrosion-resistant, firm and durable, and good stability, is not prone to the phenomenon of breaking, and shock-absorbing capacity is good, and long service life, and cost is low.
