LOCKUP DEVICE FOR TORQUE CONVERTER
Document Type and Number:
WIPO Patent Application WO/2016/103888
Kind Code:
A1
Abstract:
The present invention makes it unnecessary to supply operating oil when in a lockup state by using a hydraulic circuit which in a torque converter having two hydraulic ports. This lockup device is provided with a first clutch part (28), a piston (30), a dog clutch (32), and a first hydraulic port (P1). The first clutch part (28) is operated by means of operating oil. The piston (30) is disposed between the first clutch part (28) and a turbine (4), and transmits torque from the first clutch part (28) to the turbine (4). The dog clutch (32) has a coupling member (40) which is operated by the operating oil and is capable of mechanically coupling a front cover (2) and the piston (30). The first hydraulic port (P1) supplies the operating oil which operates the first clutch part (28) and the coupling member (40) of the dog clutch (32).
