Abstract
The utility model discloses a shock absorber piston assembly which comprises a circulation valve limiting board, an upper adjusting gasket, a circulation valve plate, a throttling sheet, a piston, a restoring valve plate, a lower adjusting gasket and a locking nut. The circulation valve limiting board, the upper adjusting gasket, the circulation valve plate, the throttling sheet, the piston, the restoring valve plate, the lower adjusting gasket and the locking nut are sequentially sleeved at one end of a piston rod, and the locking nut is screwed and fixed on a thread at the end of the piston rod. The shock absorber piston assembly is characterized by further comprising a restoring valve which is arranged between the lower adjusting gasket and the locking nut. The shock absorber piston assembly is easy to assemble and convenient to adjust.
Description
[technical field]
The utility model relates to a kind of at the inner vibration damper of installing of automobile suspension system, is specifically related to a kind of piston assembly of vibration damper.
[background technique]
Vibration damper is equipped with in suspension system inside at most of automobiles; Vibration damper forms " suspension " of automobile with damping spring; The critical component of vibration damper has its piston assembly; The structure that the piston assembly of existing technology is normally such: be included in the sheathed successively flowing valve limiting board of piston rod rod end, on adjust pad, circulation valve block, throttling sheet, piston, recovery valve block, adjust pad, spring and locking nut down; Locking nut is twisted on the rod end screw thread that is located at piston rod spring is compressed; Because the existence of spring force and the restriction of piston rod rod end screw thread protruded length are only being pressed under the situation of spring and could nut be screwed on the rod end screw thread of piston rod, assembling is not easy; And because there are certain deviation in rigidity, the length of spring, the piston assembly after the assembling is not easy to debugging.
[summary of the invention]
In view of the deficiency of existing technology, the shock absorber piston assembly that the utility model provides a kind of easy assembling, has been convenient to debug.
The utility model takes following technological scheme to accomplish:
The shock absorber piston assembly; Be included in the sheathed successively flowing valve limiting board of piston rod rod end, on adjust pad, circulation valve block, throttling sheet, piston, recovery valve block, adjust pad and locking nut down; Locking nut is tightened fixing on the rod end screw thread of piston rod; It is characterized in that: piston assembly also comprises rebuilt valve, rebuilt valve under adjust between pad and the locking nut and be provided with.
Above-mentioned shock absorber piston assembly; The spring that replaces existing structure with rebuilt valve; Advantage is: the one, and easy assembling, the 2nd, the thickness of rebuilt valve can be accomplished complete unity, needs only during assembling locking nut is tightened with certain moment of torsion; Piston assembly after the assembling has same design parameter basically, is convenient to debugging.
As preferably, rebuilt valve adopts powdered metallurgical material.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of the utility model.
[embodiment]
As shown in the figure; The shock absorber piston assembly of the utility model; Be included in the sheathed successively flowing valve limiting board 1 of piston rod rod end 10, on adjust pad 2, circulation valve block 3, throttling sheet 4, piston 5, restore valve block 6, adjust pad 7, rebuilt valve 8 and locking nut 9 down; Rebuilt valve 8 adopts powdered metallurgical material, and locking nut 9 is tightened fixing on the rod end screw thread of piston rod.
Claims (2)
1. shock absorber piston assembly; Be included in the sheathed successively flowing valve limiting board of piston rod rod end, on adjust pad, circulation valve block, throttling sheet, piston, recovery valve block, adjust pad and locking nut down; Locking nut is tightened fixing on the rod end screw thread of piston rod; It is characterized in that: piston assembly also comprises rebuilt valve, rebuilt valve under adjust between pad and the locking nut and be provided with.
