Abstract

A clutch (1) with an inner ring (2) arranged about an axis of rotation (d) and an outer ring (3) arranged coaxially in reference thereto, as well as an elastic clamping ring (4) arranged between them and radially limited thereby, with the inner ring (2) and the clamping ring (4) resting on each other via a ramp device (9), arranged bi-directionally effective in the circumferential direction, and clamping segments (13) pointing radially outwardly and arranged distributed in the circumferential direction, form in case of a radial displacement of the clamping ring (4) forming with the outer ring (3) a clamping connection in at least one circumferential direction. In a further aspect, a radial displacement of the clamping ring (4) is provided via a ramp device (12) effective in the axial direction, switched by an axial displacement of the inner ring (2) in reference to the clamping ring (4).
