Torque transmission unit for drive train of motor vehicle, has energy storage unit that pressurizes ends of friction element and has bow springs which act between end of friction element and one component

摘要

The torque transmission unit (200) has two components, a rotational axis and a friction element, where the two components are rotated relative to each other around the rotational axis. The friction element is provided for transmitting a mechanical power between the two components. An energy storage unit pressurizes the ends of the friction element and has bow springs (208,210). The bow springs act between an end of the friction element and the former component. The former component has an outer surface and the latter component has an inner surface. A receiving space (212) is formed between the outer surface and the inner surface.
