Abstract

A quiescent-current-actuated electromagnetic spring pressure brake including torque transmission sleeves disposed between a machine wall and the brake, and an axially movable armature plate having bores along its periphery to receive the torque transmission sleeves. At least one piston guide ring is provided in the area of torque transmission sleeves on the outer periphery of the latter adjacent an O-ring disposed in a groove, said piston guide ring being placed in the groove of said O-ring or in a separate groove and acting to provide a damping action in the circumferential direction and a sliding displacement of the armature plate in the axial direction.
