摘要

Mechanism friction wheel, which is associated with a drag drive belt of an internal combustion engine for a separate auxiliary unit, - wherein a friction wheel (5) which cooperates by friction in the contact zone a drive wheel (4) of the internal combustion engine or other unit with the outer side (1 ') of a belt (1') is in frictional connection with a drive wheel (6) of mechanism friction wheel (2) of the auxiliary unit (3), wherein furthermore - the friction wheel (5) is controlled by a control, if necessary, out of engagement with one of the partners of friction ( 1 ', 6), characterized in that - the friction wheel (5) is arranged variably in position in a guide device (8) which is arranged on the side adjacent the wheel drive motor (4) or drive wheel (6) respectively in the respective contact strap (1 ') along an arc section, which is equidistant from the axis of rotation (9) of the drive wheel (4, 6) respectively relative to the drive wheel (6) or with respect to outer side (1 ') of the belt in the respective contact by means of the control device (7), and is arranged so that its position can be changed to switch the auxiliary unit (3).
