Abstract
A self-energizing disc brake includes a brake-internal hydraulic arrangement with a supply circuit and an expansion vessel, a brake application device with a brake application cylinder for applying a brake pad in the direction of a brake disc, a force transmission unit which supports the brake pad at a wedge angle on the brake application device, a tangential-force absorbing cylinder for switching over the wedge angle and being operatively connected to the force transmission unit; an electric-motor actuator which acts on the brake application device via the hydraulic arrangement, a distributor cylinder arranged in series between the electric-motor actuator and the brake application device for pressure boosting, and a control unit for controlling switchover of the wedge angle between the tangential-force absorbing cylinder and the electric-motor actuator. An adjusting device adjusts brake pad wear, and has a movable screw spindle, which is operatively connected to the brake application device.
