Abstract
The present invention concerns a clamping roller switch gear ( ) whose drive element ( ) can be displaced in opposite directions out of an idling, initial position by actuation of a pivoting lever ( ). A driven element (coupling ring ) of the clamping roller switch gear ( ) and the drive element ( ) define, together with opposing clamping surfaces, wedge-shaped clamping gaps ( ) that taper in opposite directions. In these clamping gaps ( ) are arranged clamping rollers ( ) that, in the initial position of the drive element ( ), are kept out of clamping engagement with the clamping surfaces by a first housing-fixed stop ( ). According to the invention, the drive element ( ) comprises two drive members ( ) that are rotatable in opposite directions, in the initial position of the drive element ( ), these drive members are supported on housing-fixed stops, and the pivoting lever ( ) positively entrains one of the drive members ( ) in one direction of pivot and positively entrains the other drive member ( ) in the opposite direction of pivot.
