Functionally enhanced hydrokinetic device having clutch assembly operable at low engine speeds

摘要

A torque converter (10) for translating kinetic energy between a prime mover and a transmission including a torque input member (20) and an impeller assembly (12) operatively coupled for rotation with the torque input member (20). A turbine assembly (14) is fluidly connected in driven relationship with the impeller assembly (12). A clutch assembly (18, 18') is supported for selective operation with the turbine assembly (14) and interposed between the turbine assembly (14) and the torque input member (20). The clutch assembly (18, 18') may be a continuously slipping bypass clutch which is selectively movable into engagement with the torque input member (20) to provide torque translation between the torque input member (20) and the turbine assembly (14) at low engine speeds.
