Torque converter bypass clutch damper having compliant pressure disc

摘要

A hydrokinetic torque converter includes an impeller cover (12) and a bypass clutch. The impeller cover (12) has welded to it a clutch plate (70), which carries friction material (80) adjacent a clutch piston (60). The piston (60) supports a pressure disc (79) and carries it axially into engagement with the clutch plate (70). The disc (79) flexes into conformance with the surface of the clutch plate (70) beginning at a radially inner region and progressing radially outward as clutch apply pressure increases.
