The invention relates to a hydrodynamic torque converter including a turbine wheel arranged inside of a housing, a torque converter lockup clutch, an axially mounted piston, a torsional vibration damper and a hub. The turbine wheel and the piston are rotationally fixed to the input component of the damper. The input component is connected to the hub by means of a connection provided with a circumferential backlash. The output component of the damper is connected to the hub without circumferential backlash.

Hydrodynamic torque converter

The rotary output element of a hydrokinetic torque converter can receive torque with limited play from the turbine or directly from the housing by way of a damper which operates in series with a lockup clutch. The lockup clutch can be engaged to transmit torque from the housing of the torque converter to the damper and the latter then transmits torque to the output element.

Torque transmitting apparatus with hydrokinetic torque converter

A force or torque transmitting apparatus which transmits torque from the output element of a prime mover to the input element of a transmission or another driven unit in a motor vehicle by way of a hydrokinetic torque converter and/or by way of a lockup clutch. When the vehicle embodying the apparatus is coasting, the housing of the torque converter is engaged only by the friction lining on the axially movable piston of the lockup clutch when the latter is engaged, either entirely or with slip. Thus, it is not necessary to provide one or more thrust bearings between the piston of the lockup clutch and the housing of the torque converter.
