Abstract
The utility model belongs to automobile absorber product technical field, in particular to a kind of piston for damper, described piston comprises piston only and piston ring, and described piston ring and the integrated encapsulate of piston only design, and the outer wall of described piston only has been evenly arranged several slots.This shock absorber piston efficiency of assembling is high, effectively reduces the risk that piston ring comes off in the course of the work, improves sealability, thus improve the quality of products, the working life of vibration damper is improved, and alleviates trouble and difficulty that user frequently changes.
Description
Technical field
The utility model belongs to automobile absorber product technical field, particularly the integrated encapsulation piston of a kind of vibration damper.
Background technique
In prior art, piston for damper is the piston only 1 ' (as shown in Figure 1) and cupric teflin tape (i.e. piston ring 2 ' be made up of ferrous based powder metallurgical, combine as shown in Figure 2), then by interference fit by the piston press that combines on vibration damper inwall, piston is long to-and-fro motion in vibration damper.
In addition, as shown in Figure 1, described piston only 1 ' outer wall is provided with a slot, and built-up piston is in assembly process, and piston ring easily comes off, and by piston ring set on piston only, there is gap joint, easily produces leakage, poor sealing performance, product does not reach requirement, affects the working life of vibration damper.
Therefore, research and develop a kind of can difficult drop-off and to have the piston for damper of better sealability extremely urgent.
Model utility content
The purpose of this utility model overcomes the deficiencies in the prior art, a kind of improved shock absorber piston is provided, this shock absorber piston efficiency of assembling is high, the risk that effective reduction piston ring comes off in the course of the work, improve sealability, thus improve the quality of products, the working life of vibration damper is improved, alleviates trouble and difficulty that user frequently changes.
In order to realize above-mentioned technical purpose, the utility model realizes by following technological scheme:
Improved shock absorber integral piston described in the utility model, comprises piston only and piston ring, and described piston ring and the integrated encapsulate of piston only design, and the outer wall of described piston only has been evenly arranged several slots.
As the further improvement of above-mentioned technology, in the slot of described piston only outer wall, between adjacent two slots, spacing is 3-4mm, and the width of slot is 3-4mm.
As the further improvement of above-mentioned technology, the height of described piston ring is 10mm, and this height value is higher than the height of piston ring in existing, can effectively improve sealing, guiding, wear-resisting property.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model is owing to carrying out the design of integrated encapsulate by piston ring with piston, effectively prevention piston ring coming off operationally, and assembling easily and difficult drop-off, guarantees good sealability;
(2) in the utility model, owing to being evenly arranged several slots in the outer wall of piston only, non-skid property is good, effectively prevents coming off of piston ring;
(3) in the utility model, the height of piston ring is higher, and it has good sealability, leading role and wear-resisting property;
(4) piston described in the utility model, quality of product is high, and the working life of vibration damper is improved, and alleviates trouble and difficulty that user frequently changes.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Fig. 1 is piston structure schematic diagram in prior art;
Fig. 2 is piston ring structure schematic diagram in prior art;
Fig. 3 is piston structure of shock absorber schematic diagram described in the utility model.
Embodiment
As shown in Figure 3, improved shock absorber piston described in the utility model, improved shock absorber integral piston described in the utility model, comprise piston only 1 and piston ring 2, described piston ring 2 encapsulate integrated with piston only 1 designs, and the outer wall of described piston only 1 has been evenly arranged several slots 11.
In the slot 11 of described piston only 1 outer wall, between adjacent two slots 11, spacing is 3-4mm, and the width of slot 11 is 3-4mm.
The height of described piston ring 2 is 10mm, and this height value is higher than the height of piston ring in existing, can effectively improve sealing, guiding, wear-resisting property.
Piston for damper efficiency of assembling described in the utility model is high, the risk that effective reduction piston ring comes off in the course of the work, improves sealability, thus improves the quality of products, the working life of vibration damper is improved, alleviates trouble and difficulty that user frequently changes.
The utility model is not limited to above-mentioned mode of execution, if do not depart from spirit and scope of the present utility model to various change of the present utility model or modification, if these are changed and modification belongs within claim of the present utility model and equivalent technologies scope, then the utility model also comprises these change and modification.
Claims (3)
