DISC BRAKE, MOTOR VEHICLE, AIR GAP ADJUSTMENT METHOD AND DEVICE

The invention relates to a disc brake for a motor vehicle, a motor vehicle, an air gap adjustment method and an air gap adjustment device. The disc brake comprises a brake caliper; a brake bracket; a brake disc; a first brake pad and a second brake pad; a brake piston which is connected to a pressure source and which is sealingly displaceably guided in a brake caliper of the disc brake in order to effect a relative movement between the respective brake pad and the brake disc by means of an application force provided by the pressure source such that the brake pad can be brought into contact with the brake disc; and an electromagnet having a coil and a coil core movably arranged in the coil, the coil core being connected to at least one of the brake pads, preferably to a second brake pad arranged on a side of the brake disc facing away from the brake piston, in order to generate a retraction force acting on the at least one brake pad, the coil is connected to the brake bracket. 本发明涉及一种用于机动车辆的盘式制动器、机动车辆、气隙调节方法和装
