Abstract:
1. A force transmission system, comprising: a wraparound element and a frictional surface assigned to said wraparound element; a switching device configured to switch said wraparound element between a first switching state and a second switching state, said wraparound element being operatively connected in a force-transmitting relationship with said frictional surface in said first switching state, and said wraparound element being operatively connected to said frictional surface in a non-force-transmitting relationship in the second switching state, said switching device including a lever-type coupling element, a drive element, and an output element, said drive element being effective to act on said coupling element at a drive-side bearing point and said output element being effective to act on said coupling element at an output-side tilting point; a torque-controlled lever arm for fully lifting said wraparound element off said frictional surface in the second switching state, said lever arm being formed by a distance, effective at said switching device, between said drive-side bearing point and said output-side tilting point.
