Title:
LOCK-UP APPARATUS FOR TORQUE CONVERTER
Document Type and Number:
WIPO Patent Application WO/2012/147404
Kind Code:
A1
Abstract:
This lock-up apparatus in which a piston and a damper mechanism are disposed at separated positions makes it possible to conserve space in a mechanism for regulating an intermediate member. The lock-up apparatus comprises a clutch part (24) disposed between a front cover (2) and a turbine (4), and a damper mechanism (25) for transmitting torque from the clutch part (24) to the turbine (4) and for absorbing and attenuating return vibrations. The damper mechanism (25) comprises an input plate (44) whereby torque is inputted from the clutch part (24), an output plate (45) connected to the turbine (4), a plurality of torsion springs (46), an intermediate member (47), and a regulating member (48). The intermediate member (47) is able to rotate relative to the input plate (44) and the output plate (45), and causes the two torsion springs (46) to act in series. The regulating member (48) is provided to the input plate (44) and regulates the movement of the intermediate member (47) in the axial direction and in the radial direction.
