Abstract:
A switchable clamp locking mechanism comprising an output shaft (3) that rotates with respect to a rotatably fixed part, comprising a housing (1), with clamping elements, formed from clamping rollers (4), that are pushed by a spring force into a clamping gap (16) in a clamped position, and are confirmed by a smooth track (15) on the rotatably fixed part and by locking ramps (13, 14) on the output shaft (3), a drive shaft (2) to turn the output shaft (3) and a device to move the clamping elements into a released position in which the clamping elements are released to allow the output shaft (3) to turn, a slide (7) connected to the output shaft (3) is locked to the rotatably fixed part in the clamped position and is disengaged from the rotatably fixed part in the released position of the clamping elements.
