A clamp-type locking mechanism includes a housing (1) with an inner cylindrical clamping surface (3) and with driving elements (5) and driven elements (4) positioned concentrically therewith. The driven element (4) is provided with clamping ramps (23, 24) facing the clamping surface (3), which have arranged thereon clamping roller pairs formed of two clamping rollers (25) successively placed along the circumference. Both clamping rollers (25) are spring-biased by an interposed spring element (26, 30) in direction away from each other towards the clamping surface (3) and the clamping ramp (23, 24), with the driven element (4) being provided with stops (28) for claws (19) of the driving element (5). The claws (19) have on the sides facing the stops (28) contact areas (27) for one of each of the clamping rollers (25) of a clamping roller pair, wherein a circumferential clearance between the stops (28) and the claws (19) is greater than a circumferential clearance between the contact areas (27) and the clamping rollers (25). It is proposed to construct the driven element (4) in form of a thin-walled sheet metal part (6) with clamping ramps (23, 24) and stops (28) formed thereon in a non-cutting manner. It is furthermore proposed to construct the driving element (5) in form of a plastic disk (8) with integral plastic claws (19), and of a driving member (9) so connected to the plastic disk (8) that a rotation therebetween is prevented.
A clamp-type locking mechanism, comprising a housing (1) with an inner cylindrical clamping surface (3), with a driving element (5) rotatable with respect to the housing (1) and with a driven element (4) positioned coaxially with respect to the cylindrical clamping surface (3), with the driven element (4) being provided with clamping ramps (23, 24) facing the clamping surface (3) for arrangement of clamping roller pairs in the form of two clamping rollers (25) arranged successively in circumferential direction, wherein both clamping rollers (25) of the clamping roller pairs are spring-biased by an interposed spring element (26, 30) in direction away from each other towards the clamping surface (3) and the clamping ramp (23, 24), with the driven element (4) being provided with stops (28) for claws (19) of the driving element (5) which engage between two neighboring clamping roller pairs, and with the claws (19) forming contact surfaces (27) for one of each of the clamping rollers (25) of a clamping roller pair at their sides facing the stops (28), wherein a peripheral clearance between the stops (28) and the claws (19) is greater than a peripheral clearance between the contact areas (27) and the clamping rollers (25), said driven element (4) being formed by a first thin-walled sheet metal part (6) which has an annular closed sheet metal jacket drawn radially inwardly at several locations distributed about the circumference at formation of valleys (22), with the stops being formed by circumferential walls (28) of the valleys (22) and circumferentially bounding plateaus (21) provided with the clamping ramps (23, 24).
