A torque converter for a vehicle includes a front cover, an impeller configured to rotate and being coupled to the front cover, a turbine disposed to face the impeller, a turbine shell provided in the turbine, a stator disposed between the impeller and the turbine, and a lockup clutch provided with a drive hub connected to the front cover. The lock-up clutch has a drive disc provided in the drive hub, a driven disc coaxially disposed to the drive disc, and a driven hub provided with the driven disc, and a torsional damper comprising a retaining plate disposed between the lock-up clutch and the turbine. Engine torque is transmitted to the retaining plate through the front cover by a frictional contact between the drive disc and the driven disc.

Torque converter for a vehicle

A start clutch device transmits rotational power of an engine to a side of a transmission via a damper through a clutch inside a housing. The start clutch device includes a transmission input shaft, an output hub and a fixed hub unit. The transmission input shaft is connected to the transmission, and the output hub surrounds the transmission input shaft inside the housing such that rotation relative to the transmission input shaft is restrained. The output hub is coupled with the damper such that the output hub transmits the rotational power to the transmission input shaft. A fluid passes through the fixed hub unit, in which one end portion divides a space between an inner circumference of the housing and an outer circumference of the transmission input shaft, thereby defining a flow path, and the other end portion supports the output hub in the axial direction.
