Abstract
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.
Claims64
Apparatus for transmitting torque comprising a fluid-operated clutch, such as a hydrokinetic torque converter, including a housing connectable with a rotary output component of a prime mover, at least one pump receiving torque from said housing, a rotary output element connectable with a rotary input element of a driven unit, such as a variable-speed transmission, and a turbine interposed between said at least one pump and said output element;
- at least one torsional vibrations absorbing torque transmitting damper disposed in a power flow between said turbine and said output element and including an input member rotatable with said turbine, an output member connected with said output element and rotatable relative to said input member, and energy storing means arranged to oppose rotation of said members relative to each other;
- and a form-locking connection provided between and permitting at least limited angular movements of said turbine and said output element relative to each other.
