ABSTRACT:
A fluid torque converter equipped with a direct-coupling clutch comprising a front cover fixed to the pump impeller of the fluid torque converter, and a clutch disk axially slidably mounted on the output shaft of the fluid torque converter and disposed between the front cover and the turbine runner.
A friction plate affixed to a friction surface formed on the front cover is divided into two portions, namely, a radially outer portion made of a frictional material having a large coefficient of dynamical friction and a large heat capacity and a radially inner portion made of a frictional material having a large coefficient of statical friction and a high compressive strength.
