Title:
LOCK-UP DEVICE FOR TORQUE CONVERTER
Document Type and Number:
WIPO Patent Application WO/2013/154065
Kind Code:
A1
Abstract:
The present invention attempts to reduce the size of a lock-up device in the axial direction by modifying the positions of a piston and an oil chamber. This lock-up device is provided with a clutch part (24) and a damper mechanism (25). The clutch part (24) has a clutch output member (27), a clutch plate (28), a disk-shaped oil chamber plate (29), and a piston (30). The oil chamber plate (29) is disposed between a front cover (2) and a turbine inner circumferential part so that the oil chamber plate (29) cannot move in the axial direction relative to the front cover. The piston (30) is disposed between the front cover (2) and the oil chamber plate (29) so that the piston (30) can move freely in the axial direction. Moreover, the piston (30) configures a first oil chamber (L1) for lock-up with the oil chamber plate (29), and configures a second oil chamber (L2) for lock-up release with the front cover (2).
