Document Type and Number:
Japanese Patent JP6976775
Kind Code:
B2
Abstract:
A torque converter transmits a torque from a drive source to an input shaft of a transmission. The torque converter includes a front cover, an impeller, a turbine and a lock-up device. The torque is inputted to the front cover. The impeller is fixed to the front cover. The turbine is disposed in opposition to the impeller, and is coupled to the input shaft of the transmission. The lock-up device mechanically transmits the torque from the front cover to the turbine. The lock-up device includes a piston, a damper mechanism and a friction generating mechanism. The piston is disposed between the front cover and the turbine so as to be axially movable, and is capable of being engaged by friction with the turbine. The damper mechanism transmits the torque from the front cover to the piston. The friction generating mechanism generates a hysteresis torque on the piston by frictional resistance.
