摘要

Switchable free-wheel unit comprises a switching element which can be moved into a position or several positions using air or current so that power or torque transfer from a drive part via rolling bodies or molded parts to a driven part occurs using a frictionally engaged slave unit. Preferred Features: The free-wheel unit has clamping bodies arranged as rolling bodies (6) between a support (2) and clamping ramps (5) of a clamping ring (4) which rotates in a housing (1).
