Free-wheel unit e.g. electrically switchable free-wheel unit, has magneto-rheological unit inserted into clamping gap, where magneto-rheological unit includes switch unit that is provided with magnetic field unit

摘要

The unit has an inner ring (10a) and an outer ring (11a) and a clamping unit arranged in a clamping gap. A magneto-rheological unit (16a) is inserted into the clamping gap, where the magneto-rheological unit includes a switch unit (17a) that includes a magnetic field unit (19a), which is provided to produce a magnetic field in the clamping gap. The switch unit is provided to actuate a switching operation in an operating mode, and another spring unit (20a) exerts force on the clamping unit. An independent claim is also included for a method for providing a free-wheel unit with an inner ring and outer ring.
