Title:
PISTON SEALING ASSEMBLY FOR CLUTCH DISENGAGEMENT SYSTEM AND CLUTCH DISENGAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/041325
Kind Code:
A1
Abstract:
Provided are a piston sealing assembly for a clutch disengagement system and the clutch disengagement system. The piston sealing assembly comprises: a frame (1) having an annular shape, the frame (1) extending in an axial direction thereof by a pre-set length; and a sealing part (2) adhered to the frame (1) and extending circumferentially over the entire circumference of the frame (1), wherein the sealing part (2) comprises a first main lip part (21) and a second main lip part (22), the first main lip part (21) extends from a radial outside face of the frame (1) towards the radial outer side thereof, and the second main lip part (22) extends from a radial inside face of the frame (1) towards the radial inner side thereof, so that the first main lip part (21) and the second main lip part (22) are separated by the frame (1). The frame (1) is arranged so that the first main lip part (21) located on the radial outer side and the second main lip part (22) located on the radial inner side are completely separated, and the mutual influence of the deformation of the sealing lips (21, 22) of the piston sealing assembly is eliminated simply and effectively, such that the piston sealing assembly will not easily fail. In addition, the frame (1) improves the strength of the entire piston sealing assembly, such that the piston sealing assembly can withstand larger pressures.
