ABSTRACT:
A hydrokinetic torque converter for use with a transmission in the power train of a motor vehicle has a housing rotatable by the engine and containing a pump, a turbine and at least one stator as well as a rotary output device connected to the input shaft of the transmission. The pump is normally rotatable by the housing; the turbine is rotatable (a) by the fluid which is circulated by the pump or (b) by the housing in response to engagement of a lockup clutch; and the stator can be connected to the stationary case of the transmission or is rotatable by the circulating fluid. First and second hubs are non-rotatably but axially movably mounted on the output member and are respectively connectable with the turbine and the stator by suitable clutches. The hubs can move axially relative to the output device between several positions in one of which the turbine can drive the input element of the transmission in a forward direction, in another of which the stator can rotate the input element in a direction to drive the vehicle rearwardly, and in a third of which the transmission is in neutral gear.
