A torque converter (1) including a front cover (2), a torque converter main body housing (3) and a retarder (5). The front cover (2) is coupleable to a crankshaft of an engine. The torque converter main body housing (3) is coupled to the front cover (2) forming a hydraulic fluid chamber (A). The torque converter (1) outputs torque transmitted from the front cover (2) to the main drive shaft (34). The retarder (5) is arranged inside the hydraulic fluid chamber (A) and uses the fluid to dampen torque transmitted from the torque converter main body housing (3) to the main drive shaft (34).

Torque converter having a retarder mechanism therein

A lockup unit for a torque converter is provided with a front cover coupled to an input member and a turbine coupled to an output member. The lockup unit includes: a disc-like piston disposed movably between the front cover and the turbine and pressingly contactable against the front cover; a flexible coupling mechanism for coupling the disc-like piston and the turbine in a circumferential direction; and a frictional resistance generating mechanism including a stationary member fixed to the disc-like piston and a flexible member which is brought into pressing contact with the stationary member so as to be rotatable together with the turbine, for generating a frictional resistance when the piston and the turbine are rotated relative to each other, to thereby reduce the number of the necessary mechanical components.

Lockup unit for torque converter having a friction element

A power transmission mechanism equipped with a fluid coupling, an input shaft thereof interconnected to a power source being interconnected through the fluid coupling to an output shaft, and the output shaft being interconnected to a forward-rearward changeover mechanism including a speed changer; characterized by that forward-rearward changeover can be performed by providing a clutch mechanism in a housing of said fluid coupling, which automatically disengages a connection between the input shaft and the output shaft when the power source is in idling condition, and automatically engages it when the power source exceeds the idling condition.

Power transmission mechanism equipped with fluid and centrifugal clutch

A power transmission for an automobile, which is provided with an oil circulation type fluid coupling and a clutch mechanism so that power may be transmitted from an output shaft of an engine to an input shaft of a gear transmission. The output and input shafts support an intermediate shaft to which a pump at the fluid coupling is rotatably supported, so that a partition for supporting the intermediate shaft is eliminated. At the fluid coupling are provided an oil-charge passageway for charging to the fluid coupling a part of lubricating oil for the engine and an oil-return passageway for collecting into an engine oil pan the oil flowing out of the fluid coupling.
