Abstract
A driving arrangement with a free-wheel coupling has a coupling sleeve (1) and a coupling hub (10) rotatably supported in the coupling sleeve (1). Both are connected, via locking pawls (24), so that, during driving of the coupling hub (10), a slaving of the coupling sleeve (1) takes place. However, a faster rotation of the coupling sleeve (1) is allowed so that the coupling sleeve (1) can overtake the coupling hub (10). Belleville springs (25, 29) achieve a breaking effect with large lagging masses. The Belleville springs (25, 29) are kept non-rotational relative to the coupling hub (10) and are supported on the end faces (8, 9) of the coupling sleeve (1). The Belleville springs (25, 29) are pre-tensioned by means of a friction face (26).
