Abstract
The utility model discloses a wet brake piston bidirectional X-type sealing mechanism which comprises a hub, an annular gear, a piston, a connection disk and a braking device. A jacking return mechanism is arranged on the annular gear at the left end of the piston; a sealing ring is arranged between the piston and the connection disk; and the section of the sealing ring is X-shaped. Compared with the prior art, the wet brake piston bidirectional X-type sealing mechanism has the advantages that the sealing ring is arranged between the piston and the connection disk, so that the sealing ring is not likely to be damaged when straight reciprocating motion is carried out between the piston and the connection disk for a long time and the problem of high failure rate of sealing between the piston and the connection disk is solved.
Description
Technical field
The utility model relates to wet brake, relates in particular to a kind of wet brake piston two-way X-type sealing mechanism, belongs to mechanical field.
Background technique
In the ransaxle wet brake, the most design of the motive sealing of piston and oil cylinder is with O type circle seal ring.O type circle is in the whole life cycle of break, because the needs of braking make piston and cylinder body carry out for a long time straight reciprocating motion, the seal ring of O type cross section and other section type is easy in use be reversed into twisted shape, thereby causes seal failure, damages.
The model utility content
The utility model provides a kind of wet brake piston two-way X-type sealing mechanism in order to solve the above-mentioned deficiency of prior art.
Above-mentioned purpose of the present utility model realizes by following technological scheme: a kind of wet brake piston two-way X-type sealing mechanism, comprise wheel hub, ring gear, piston, tie-plate and braking device, the ring gear of described piston left end is provided with the jack-up return mechanism, be provided with seal ring between described piston and tie-plate, the cross section of described seal ring is X-shaped.
The utility model advantage compared with prior art is: be provided with seal ring between piston and tie-plate, make not fragile seal ring when carrying out straight reciprocating motion for a long time between piston and tie-plate, solved and sealed troublesome problem herein.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of wet brake piston two-way X-type sealing mechanism, comprise wheel hub 1, ring gear 2, piston 3, tie-plate 4 and braking device 5, the ring gear 2 of described piston 3 left ends is provided with jack-up return mechanism 6, be provided with seal ring 7 between described piston 3 and tie-plate 4, the cross section of described seal ring 7 is X-shaped.
But above-mentioned embodiment is exemplary, is to be this patent to be comprised the restriction of scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
