Abstract
The invention relates to a disc brake to be opened by torque, the disc brake being arranged between a drive shaft ( ) and a driven shaft ( ) and comprising a brake wheel ( ) arranged on the driven shaft ( ) non-rotatably in the peripheral direction; a friction surface ( ) arranged to cooperate with the brake wheel ( ); a spring device ( ) arranged to press the brake wheel ( ) axially against the friction surface ( ) and means ( to ) causing, by the action of the torque and torsion of the drive shaft ( ) and a possible counter-torque of the driven shaft ( ), the brake wheel ( ) and the friction surface ( ) to drift axially apart and, accordingly, the braking coupling between them to loosen against the spring force of the spring device ( ), whereby the drive shaft ( ) and the driven shaft ( ) are interconnected in such a way that they may turn a restricted rotational angle with respect to each other and that means for causing said axial displacement and for loosening the braking coupling comprise cam means ( to ) arranged between the brake wheel and the drive shaft.
