Abstract:
1. A self-boosting electromechanical friction brake, comprising a friction brake lining which is movable in a direction of rotation and into contact with a brake body, an electromechanical actuation device with which the friction brake lining can be pressed for braking against the brake body, a ramp mechanism which braces the friction brake lining at a ramp angle to the brake body, the ramp mechanism having a roller bearing that has roller bodies, with which roller bearing the friction brake lining is movably supported at a wedge angle to the brake body, and roller support means supporting the roller bodies fixedly and rotatably on a component of the friction brake, wherein axes of rotation of the roller bodies have a transverse inclination, so that the roller bodies brace the friction brake lining centrally to an imaginary circular circumferential line with its center on an axis of rotation of the brake body which divides a surface, oriented toward the brake body, of the friction brake lining into two faces of at least approximately equal size.
