Kind Code:
A3
Abstract:
The invention relates to an adjusting device (11a) for adjusting friction surface wear on brake linings (3) and a brake disk (2) of a disk brake (1), especially for a motor vehicle, comprising a brake application device, preferably a rotary brake lever (9), the adjusting device (11a) being couplable to the brake application device, preferably the rotary brake lever (9), on the drive side, and to a spindle unit (5, 5') of the disk brake (1) on the output side. The adjusting device (11a) comprises: a) a drive element on both sides of which a rolling element assembly is axially arranged, one of which is designed as a rolling bearing and the other as a ball ramp clutch with a freewheel; b) a pressure element coupled to the ball ramp clutch and forming an overload clutch together with a portion of the ball ramp clutch; c) an output element coupled to the pressure element for coupling to a coupling wheel (20a), which is designed for coupling to the spindle unit (5, 5'); d) an energy storage element for generating a pre-tensioning force of the ball ramp clutch and the overload clutch; and e) a support body, one end of which is connected to a bearing plate and around which the drive element, the rolling element assemblies, the overload clutch, the output element and the energy storage element are arranged axially in series with the bearing plate, the energy storage element being arranged between a bearing portion of the support body and the pressure element. The invention further relates to a disk brake (1) comprising the adjusting device (11a) and a method for operating a wear adjustment device (11).
