Abstract

A free-running roller coupling transmits in both directions of rotation a torque between two structural members. This coupling has an outer ring in which clamping tracks are formed by recesses. An inner element has a cylindrical clamping track. Pairs of clamping rollers, prestressed by a pressure spring against the ramp-like end of each clamping track, are arranged between the clamping track of the inner element and the clamping tracks of the outer ring. An unblocking arrangement has comb-like carriers that extend through slots in an edge of the outer ring, which carriers can unblock the rollers while allowing the outer ring to be driven by a switching sleeve.
