Clutch for powertrain of motor car, has positioning unit aligning clutch disk, and comprising element, which contactlessly exerts repulsive magnetic force counteracting tilt of clutch disk in bearing with open clutch

摘要

The clutch (1) has a clutch disk (3) that is mounted on a shaft (5) in a shaft bearing (7) such that the clutch disk receives and transmits a torque. A positioning unit (8) aligns the clutch disk with the open clutch, and comprises an element (9) e.g. permanent magnet and electromagnet, which is provided around a radial outer periphery of the clutch disk in a radial distance (R) to a rotational axis (A). The element contactlessly exerts a repulsive magnetic force counteracting a tilt of the clutch disk in the bearing with the open clutch.
