Title:
LOCKUP DEVICE FOR TORQUE CONVERTER AND METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2016/103891
Kind Code:
A1
Abstract:
The present invention pertains to a device which mechanically couples a front cover to an output side, thereby eliminating the need to supply hydraulic oil when in a locked state, wherein a shock occurring when transitioning from a locked state to an unlocked state is suppressed. This device is provided with a first clutch part (28), a piston (30), and a dog clutch (32). The first clutch part (28) allows torque to be transmitted between the front cover (2) and a turbine (4) when transitioning between the locked and unlocked states, and prevents torque from being transmitted while in the unlocked state or the locked state. The piston (30) transmits torque from the first clutch part (28) to the turbine (4). The dog clutch (32) has a coupling member (40) which couples the front cover (2) and the piston (30) while in the locked state and decouples the front cover (2) and the piston (30) while in the unlocked state.
