Document Type and Number:
Japanese Patent JP2016118286
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To dispense with supply of a hydraulic fluid in a lock-up state by using a hydraulic circuit applied to a torque converter having two hydraulic ports.SOLUTION: A lock-up device includes a first clutch portion 28, a piston 30, a dog clutch 32, and a first hydraulic port. The first clutch portion 28 is operated by a hydraulic oil. The piston 30 is disposed between the first clutch portion 28 and a turbine 4, and transmits the torque from the first clutch portion 28 to the turbine 4. The dog clutch 32 has a connecting member which is operated by a hydraulic oil and is capable of mechanically connecting a front cover 2 and the piston 30.
