Disk brake and adjusting device for a disk brake
The invention relates to a disk brake, in particular for utility vehicles, having a brake application shaft ( 14 ) and having an adjusting device for wear-dependent adjustment, wherein a rotational axis ( 36 ) of the brake application shaft is perpendicular to a rotational axis ( 40 ) of the adjusting device and a pin ( 23 ) serves to couple the brake application shaft to the adjusting device. A longitudinal axis of the pin encloses an acute angle with the rotational axis of the brake application shaft. The invention also relates to an adjusting device for a disk brake, in particular for utility vehicles, having an adjusting element in the form of an adjusting nut or an adjusting screw, and having a slipping clutch ( 28, 30 ) for limiting the torque which can be transmitted to the adjusting element. The slipping clutch has a friction element which is rotationally coupled to the adjusting element in both rotational directions.
