Abstract:
A friction brake, comprisinga carrier,at least one friction lining supported on the carrier and interacting with at least one friction surface, and at least one device for actuating the friction lining against the friction surface causing a servo effect,wherein means are provided which permit varying the servo effect during operation of the brake,wherein a central force action point between the friction lining and the friction surface and a central force support point of the friction lining, with a virtual connecting line between the two points, and with a normal force acting on the friction lining, wherein means to vary the servo effect are configured as an adjusting mechanism which permits variations of the angle between the connecting line and the direction of the normal force acting on the friction lining,wherein the friction brake is configured as a duplex brake,wherein the variations of the angle arc made by adjusting the central force support point of the friction lining,wherein the adjusting mechanism is provided by a sliding carriage which is adjustable by a drive and represents the central force support point,wherein the drive is an electric actor.
