It is applied to at, DCT, CVT and HT. It provides return support for the clutch pressure piston of the transmission during gear shifting. It seals the centrifugal oil pressure generated by the rotation of the clutch in the balance chamber, which is well matched with the return spring and positioning circlip. It can withstand high and low temperatures of - 40 ~ 150 ℃, and can meet 2 million reciprocating cycles in the bench test. Targeted matching design can be carried out according to the oil cavity shape of different automatic transmissions.
