Abstract
The utility model discloses a piston of a shock absorber. The piston is capable of reducing lateral abrasion, so that the performance of the whole shock absorber is guaranteed. The piston of the shock absorber comprises a body (1), wherein the side face of the body (1) is coated by a wear-resisting layer (2); guide oblique planes are arranged at the left end and the right end of the wear-resisting layer (2); the side face of the body is provided with a first ring-shaped bulge (4), a second ring-shaped bulge (5), a third ring-shaped bulge (6), a fourth ring-shaped bulge (7) and a fifth ring-shaped bulge (8), so as to provide resistance along an axial direction of the body (1) for the wear-resisting layer (2); the ring-shaped bulges are distributed from left to right in sequence along the axial direction of the body (1); and the right end face of the wear-resisting layer (2) props against the left end face of the fifth ring-shaped bulge (8).
Description
Technical field
The utility model relates to the vibration damper technical field, specifically is a kind of shock absorber piston.
Background technique
In use for some time, wearing and tearing often appear in the side of shock absorber piston, thereby cause fluid from the fray seepage, make the performance of whole vibration damper reduce.
The model utility content
The technical problems to be solved in the utility model is a kind of shock absorber piston that can reduce side abrasion to be provided, thereby to have ensured the performance of whole vibration damper.
The technical solution of the utility model is, the utility model shock absorber piston, it comprises body, the side of body is coated with one deck wearing layer, two, the left and right sides of wearing layer is equipped with guiding surface, described side is provided with first annular projection, second annular projection, the 3rd annular projection, Fourth Ring shape projection, five rings shape projection think wearing layer provide along body shaft to resistance, these annular projections along body shaft to distributing in regular turn from left to right, distance between first annular projection and second annular projection, distance between second annular projection and the 3rd annular projection, the 3rd annular projection all equates with distance between the shape projection of Fourth Ring, distance between the 3rd annular projection and the Fourth Ring shape projection is less than the distance between Fourth Ring shape projection and the five rings shape projection, and the left side of the right side of wearing layer and five rings shape projection offsets.
After adopting said structure, the utility model compared with prior art, have the following advantages: because the side firm attachment of body has one deck wearing layer, firm attachment by first annular projection, second annular projection, the 3rd annular projection, Fourth Ring shape projection, five rings shape projection for wearing layer provide along body shaft to resistance and the bigger area of contact in side of wearing layer and body realize bigger adhesion, so the utlity model has the advantage that can reduce side abrasion, thereby ensured the performance of whole vibration damper.
As improvement, wearing layer is polychlorostyrene PVF layer, and like this, this material behavior has strong adhesion, stable good advantage, more is conducive to the raising of the utility model performance.
Description of drawings
Fig. 1 is that the axle of the utility model shock absorber piston cuts open figure.
Shown in the figure, 1, body, 2, wearing layer, 3, guiding surface, 4, first annular projection, 5, second annular projection, the 6, the 3rd annular projection, 7, Fourth Ring shape projection, 8, five rings shape projection.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model shock absorber piston, it comprises body 1, the side of body 1 is coated with one deck wearing layer 2, two, the left and right sides of wearing layer 2 is equipped with guiding surface 3, described side is provided with first annular projection 4, second annular projection 5, the 3rd annular projection 6, Fourth Ring shape projection 7, five rings shape projection 8 thinks that wearing layer 2 provides along the axial resistance of body 1, these annular projections axially distribute from left to right in regular turn along body 1, distance between first annular projection 4 and second annular projection 5, distance between second annular projection 5 and the 3rd annular projection 6, the 3rd annular projection 6 all equates with distance between the Fourth Ring shape projection 7, distance between the 3rd annular projection 6 and the Fourth Ring shape projection 7 is less than the distance between Fourth Ring shape projection 7 and the five rings shape projection 8, and the left side of the right side of wearing layer 2 and five rings shape projection 8 offsets.
Wearing layer 2 is polychlorostyrene PVF layer.
