Apparatus for transmitting force between rotary driving and driven units

摘要

An apparatus which serves to transmit force between the crankshaft of an internal combustion engine and the input shaft of a variable-speed transmission in a motor vehicle has a hydraulic clutch with one or more pumps, stators and turbines. The casing of the hydraulic clutch is driven by the crankshaft, and the turbine(s) drives or drive a hub which transmits torque to the input shaft. One or more elastic dampers are installed in the casing to permit pronounced angular movements (within preselected limits) of the casing and the hub relative to each other. Each damper comprises energy storing elements, e.g., arcuate coil springs, acting at least in the circumferential direction of the casing. A lock-up clutch can be installed in the casing in series with the damper or dampers.
