Technical field
The utility model relates to vibration damper, especially a kind of column support type vibration damper.
Background technique
Usually, in order to suppress the impact from road surface, increase smoothness and the travelling comfort of travelling, suspension system is installed on automobile, suspension system comprises vibration damper and is used for the spring of shock-absorbing, and automobile is when the road surface section through uneven, although the shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion and produces bounce-back concussion, the concussion that the arranging of vibration damper produces in the time of can suppressing bounce-back after the spring shock-absorbing.General column support type vibration damper unites two into one due to vibration damper and load pillar, wheel directly is fixed on the piston rod of vibration damper, wheel torque transmits by piston rod and shock strut, and the damper structure of this structure is simple, be easy to folding and unfolding, and quality is little.Yet the vibration damper of said structure not only bears axial force due to piston rod but also bears moment of flexure, wearing and tearing and catching phenomenon easily appear, and owing to being open oil circuit design, thereby the oil sealing of column support type shock absorber easily wearing and tearing makes the sealability variation of vibration damper cause leakage of oil can not bear larger pressure, reduces working life.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of column support type vibration damper, and this vibration damper has good airproof performance and is difficult for leaking, and reduces the advantage of fretting wear.
To achieve these goals, the technical solution adopted in the utility model is: a kind of column support type vibration damper, comprise clutch release slave cylinder cylindrical shell and oil storage cylinder, the clutch release slave cylinder barrel jacket is located in oil storage cylinder, be provided with piston rod in the clutch release slave cylinder cylindrical shell, piston rod one end is provided with piston assembly, the piston rod the other end is provided with the oil sealing guiding assemblage, piston assembly comprises piston and piston ring, the oil sealing guiding assemblage comprises oil sealing and guider, oil sealing comprises primary seal lip and secondary sealing lip, it is characterized in that: described piston ring is seamless sealing ring structure, described piston ring inwall is provided with some annular grooves, described annular groove cross section is the trapezium structure of vertical placement, described trapezoidal upper base is towards described piston outer wall, described piston outer wall is provided with the convex tendon coordinated with described annular groove, described piston ring set is located on described piston and piston ring and described piston intermesh.
As further setting of the present utility model, described piston ring one end is provided with ridge shape shirt rim, and the described piston ring the other end is provided with chamfering transition limit.
As further setting of the present utility model, described chamfering transition limit and described annular groove interference fit.
As further setting of the present utility model, described oil sealing also comprises dust excluder lips.
As further setting of the present utility model, the lip of described primary seal lip and secondary sealing lip is provided with the oil storage tank that the 6-10 bar is arranged in parallel.
As further setting of the present utility model, described oil storage tank is trapezoidal projection by cross section and is spaced and is formed by connecting, connect and compose by the concave arc-shaped section transition oil storage tank that cross section takes the shape of the letter U between described trapezoidal projection and trapezoidal projection, the opening end of described U-shaped is become and is greatly horn-like gradually by the U-shaped bottom.
Adopt such scheme, in the utility model, piston ring set is located on piston and piston ring and piston intermesh, piston ring one end is provided with ridge shape shirt rim, the piston ring the other end is provided with chamfering transition limit, chamfering transition limit and annular groove interference fit, guaranteed the reliability of piston assembly assembling, piston ring and piston make coordinating of piston and piston ring tight by annular groove and the engagement fit of convex tendon, difficult drop-off, reduced relative movement between the two, the wearing and tearing of abrasion-proof piston ring have been reduced, extended vibration damper working life, improved its sealability simultaneously, Leakage prevention.There is a certain amount of lubricant oil between the oil storage tank of the lip setting of primary seal lip and secondary sealing lip, the existence of lubricant oil can avoid vibration damper to occur that because lacking lubricant oil dry friction makes the reduction oil sealing problem in working life in reciprocating process, thereby has extended the working life of vibration damper.
Below in conjunction with accompanying drawing, the utility model is further described.
