The invention concerns a step-by-step mechanism with a housing (2) in which an outer ring (3) and an output element (4) are disposed, the outer ring (3) comprising double-clamp ramps (6) and the output element (4) comprising an inner clamping track (7), and, in an annular space (8) formed between the outer ring (3) and the output element (4), clamping bodies (9) being disposed which cooperate with the double-clamp ramps (6), the clamping bodies (8) being spring-loaded. Provided in the housing (2) is a sleeve (10) which is rigid with the latter, and spring elements (13) which spring-load the clamping bodies (9) are supported on the sleeve (10). |
