Abstract
The utility model discloses a built-in gear-shifting cylinder assembly which comprises a cylinder body and a piston disc, wherein a Y-shaped sealing ring which is in sliding and sealing match with the cylinder body is arranged on the external cylindrical surface of the piston disc; an annular flange is arranged on the external cylindrical surface of the piston disc; the Y-shaped sealing ring is provided with an annular groove matched with the annular flange; and the parts of the Y-shaped sealing ring, positioned at two sides of the annular flange, are symmetrically relative to the annular flange. As for the built-in gear-shifting cylinder assembly, the matched surface between the piston disc and the Y-shaped sealing ring is cylindrical, the process is simple, the processing accuracy is easily ensured, and the sealing effect of the Y-shaped sealing ring can be well ensured; and simultaneously, for the Y-shaped sealing ring with two symmetrical ends, the axial span is longer, and the stability of reciprocating motion can be well ensured.
Description
Technical field
The utility model relates to a kind of gearshift cylinder.
Background technique
Existing built-in gearshift cylinder assembly, its piston plate is provided with two O RunddichtringOs, and piston plate cooperates with the cylinder block slipper seal by the O RunddichtringO.Guarantee sealing effect, the dimension precision requirement of the annular groove of placement O RunddichtringO is higher on the piston plate, and difficulty of processing is bigger.In actual conditions, because piston plate also has the effect of stable plunger bar, in piston plate reciprocatingly slides process, dimensional accuracy reason owing to annular groove, can cause each one of O RunddichtringO to be positioned at the frictional force difference of cylinder block, the magnitude of interference difference, thus influence the stability of piston rod movement.
Therefore need improve the piston plate of built-in gearshift cylinder of the prior art and the sealing configuration between cylinder block,, reduce rate of fault, and guarantee the stability of reciprocating motion of the pistons to improve its sealing effect.
The model utility content
In view of this, the purpose of this utility model provides a kind of built-in gearshift cylinder assembly, and it improves the sealing configuration between piston plate and cylinder block, makes its sealing effect better, and the stability of reciprocating motion of the pistons is higher.
The built-in gearshift cylinder assembly of the utility model, comprise cylinder block and piston plate, described piston plate external cylindrical surface is provided with the y-type seal ring that cooperates with the cylinder block slipper seal, described piston plate external cylindrical surface is provided with annular flange flange, described y-type seal ring is provided with the annular groove that cooperates with annular flange flange, and described y-type seal ring is positioned at the part of annular flange flange both sides with respect to the annular flange flange symmetry.
The beneficial effects of the utility model: the built-in gearshift cylinder assembly of the utility model, the fitting surface of its piston plate and y-type seal ring is the cylndrical surface, and processing is simple, and machining accuracy guarantees easily, from sealing effect that can fine assurance y-type seal ring; Simultaneously, the y-type seal ring of this structure two ends symmetry, its axial span is longer, can well guarantee reciprocating stability.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the built-in gearshift cylinder assembly of a utility model structural representation.
Embodiment
Fig. 1 is the built-in gearshift cylinder assembly of a utility model structural representation.
As shown in the figure, the built-in gearshift cylinder assembly of present embodiment, comprise cylinder block 1 and piston plate 2, described piston plate 2 external cylindrical surfaces are provided with the y-type seal ring 3 that cooperates with the cylinder block slipper seal, described piston plate 2 external cylindrical surfaces are provided with annular flange flange 2a, described y-type seal ring 3 is provided with the annular groove that cooperates with annular flange flange 2a, and described y-type seal ring 3 is positioned at the part of annular flange flange 2a both sides with respect to annular flange flange 2a symmetry.The built-in gearshift cylinder assembly of the utility model, the fitting surface of its piston plate and y-type seal ring is the cylndrical surface, and processing is simple, and machining accuracy guarantees easily, from sealing effect that can fine assurance y-type seal ring; Simultaneously, the y-type seal ring of this structure two ends symmetry, its axial span is longer, can well guarantee reciprocating stability.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
