Abstract
The utility model provides a piston for a low speed gear of an automobile gearbox. The piston comprises an annular piston body and two sealing pieces, wherein an internal annular groove and an external annular groove are formed on the internal ring and the external ring of the annular piston body respectively; and the two sealing pieces are embedded into the internal annular groove and the external annular groove respectively. By the technical scheme, the piston for the low speed gear of the automobile gearbox is provided, and the sealing pieces can be conveniently replaced, so that cost is reduced.
Description
Technical field
The utility model relates to a kind of auto parts machinery, and particularly a kind of automobile gearbox bottom gear is used piston.
Background technique
At present, existing a kind of automobile gearbox bottom gear is used piston, generally comprises the piston only of ring-type, on the inner ring face of described annular piston body, outer ring face, is equipped with Sealing, described Sealing and piston only integrated injection molding.
But the automobile gearbox bottom gear of this structure is used piston, owing to Sealing and the injection moulding of piston only one, after the Sealing breakage, can only whole piston all be changed, thereby make cost high, has also caused unnecessary waste.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of existing technology, the utility model provides a kind of automobile gearbox bottom gear to use piston, can be convenient for changing Sealing, thereby reduce cost.
The technological scheme of the utility model: a kind of automobile gearbox bottom gear is used piston; Include the piston only of ring-type; Two sealings; Be respectively arranged with interior annular groove, outer ring groove on the inner ring of described annular piston body, the outer ring, described two Sealings are embedded respectively in described in annular groove, the outer ring groove.
Adopt technique scheme; Described two Sealings are embedded respectively in described in annular groove, the outer ring groove, after the Sealing breakage, only need directly Sealing to be taken out change to get final product like this; Need whole piston not changed, thereby reduce cost.
The further setting of the utility model: described two Sealings are rubber seal.
Adopt above-mentioned further setting, Sealing is set to rubber seal, and not only cost is low, and good seal performance.
Description of drawings
Fig. 1 is the overall structure schematic representation of the utility model specific embodiment;
Fig. 2 is the structure sectional view of the utility model specific embodiment.
Embodiment
Like Fig. 1, shown in 2; A kind of automobile gearbox bottom gear is used piston; Include the piston only 1 of ring-type; Two sealings 2,3, annular groove 111, outer ring groove 121 in being respectively arranged with on the inner ring 11 of described annular piston body 1, the outer ring 12, described two Sealings 2,3 are embedded in described in annular groove 111, the outer ring groove 121 respectively.Described two Sealings 2,3 are embedded respectively in described in annular groove 111, the outer ring groove 121; Like this after Sealing 2,3 breakages; Only need directly Sealing 2,3 to be taken out to change to get final product, need whole piston not changed, thereby reduce cost.
In the utility model specific embodiment, described two Sealings 2,3 are rubber seal.
Claims (2)
1. an automobile gearbox bottom gear is used piston; Include the piston only of ring-type; Two sealings; It is characterized in that: be respectively arranged with interior annular groove, outer ring groove on the inner ring of described annular piston body, the outer ring, described two Sealings are embedded respectively in described in annular groove, the outer ring groove.
2. automobile gearbox bottom gear according to claim 1 is used piston, it is characterized in that: described two Sealings are rubber seal.
