摘要： A self-energizing disc brake includes a brake-internal hydraulic arrangement with a supply circuit and an expansion vessel; a brake application device having a cylinder for applying a brake pad toward a brake disc; a force transmission unit supporting the brake pad at a wedge angle on the brake application device; a tangential-force absorbing cylinder for switching over the wedge angle, which is operatively connected to the force transmission unit; an electric-motor actuator for acting on the brake application device via the hydraulic arrangement; and a control unit. The force transmission unit has a deflection lever and a shoulder element attached thereto. Rolling surfaces thereof are in contact with respective corresponding rolling surfaces of a brake application element of the cylinder and a brake pad support device. The deflection lever has a pressure section with a rolling surface in operative connection with the tangential-force absorbing cylinder.

摘要： A disc brake includes an inner pad and an outer pad, a pressing device, and a housing. The pressing device includes: at least one first pressing member movable toward a rotor and at least one second pressing member movable away from the rotor; and a frame held by the housing movably in an axial direction and configured to be moved by movement of the at least one second pressing member. A point of action of a resultant force of at least one pressing force applied from the at least one first pressing member to the inner pad is located on a trailing side of a centroid of the inner pad, and/or a point of action of a resultant force of at least one pressing force applied from the at least one second pressing member to the frame is located on a leading side of a frame central axis.

The retainer main shaft is shaft provided in the vehicle for power transfer from the engine onto the wheels. The retainer chassis is perpendicularly connected to the retainer main shaft and provides a rigid support to the retainer main shaft. The brake assembly is connected to the retainer main shaft through a plurality of ball bearings. The turbine assembly is mounted over the brake assembly. The locker assembly is connected to the brake assembly through a plurality of cams. The locker assembly is further connected to the turbine assembly through a locker base. The buffer is connected between the brake assembly and the turbine assembly to redistribute an excess pressure exerted on the turbine assembly.
