The present invention concerns a clamping roller switch gear (1) whose drive element (10) can be displaced in opposite directions out of an idling, initial position by actuation of a pivoting lever (3). A driven element (coupling ring 15) of the clamping roller switch gear (1) and the drive element (10) define, together with opposing clamping surfaces, wedge-shaped clamping gaps (37, 38) that taper in opposite directions. In these clamping gaps (37, 38) are arranged clamping rollers (39) that, in the initial position of the drive element (10), are kept out of clamping engagement with the clamping surfaces by a first housing-fixed stop (42). According to the invention, the drive element (10) comprises two drive members (13, 14) that are rotatable in opposite directions, in the initial position of the drive element (10), these drive members are supported on housing-fixed stops, and the pivoting lever (3) positively entrains one of the drive members (13) in one direction of pivot and positively entrains the other drive member (14) in the opposite direction of pivot.
A clamping roller switch gear (1) comprising a drive element (10) that can be displaced in opposite directions out of an idling, initial position by actuation of a pivoting lever (3), said clamping roller switch gear (1) further comprising a driven element (5), said drive and driven elements defining together with mutually opposing clamping surfaces, wedge-shaped clamping gaps (37, 38) that taper in opposite directions and in which clamping rollers (39) are arranged that, in the initial position of the drive element (10) are kept out of clamping engagement with the clamping surfaces by a first housing-fixed stop (42), characterized in that the drive element (10) comprises two drive members (13, 14) that are rotatable in opposite directions, in the initial position of the drive element (10) both these drive members (13, 14) are supported on housing-fixed stops, and the pivoting lever (3) positively entrains one of the drive members (13) in one direction of pivot and positively entrains the other of the drive members (14) in the opposite direction of pivot.
