Compressed-air actuated disk brake
First Claim
1. In a compressed-air actuated disk brake comprising a caliper which reaches around a brake disk and an application device connected to the caliper on a first side of the brake disk;
- the application device including a pivoting lever supported at a first end region to the caliper by an essentially semicircular pivot bearing so as to swivel about an axis of rotation parallel to the plane of the brake disk, a rotatably disposed eccentric connects the pivoting lever to a traverse member displaceable with respect to the brake disk and the caliper, and a second end region of the pivoting lever receiving a braking force input;
the improvement comprising;
the pivoting lever having essentially a fork-shaped with two legs extending from the second end region of the pivoting arm and each leg terminating in a separate first end region;
each first end region engaging a respective separate semicircular pivot bearing and an eccentric;
an eccentric bearing for each eccentric; and
theoretical points of the introduction of force of the pivot bearings and the eccentric are essentially on the center line of the corresponding leg.

Abstract
A compressed-air actuated disk brake is disclosed comprising a caliper which reaches around a brake disk and on one side of which an application device is arranged which, when acted upon by compressed air, actuates at least one adjusting spindle adjustably arranged in a traverse, which adjusting spindle, by way of a pressure element disposed on its brake-disk-side end, acts upon the pressure plate of a brake lining which is disposed on the application side in the caliper to be displaceable with respect to the brake disk, an adjusting device, by acting upon the adjusting spindle(s), keeping the ventilating play, which changes because of the wear of the lining, essentially constant. In order to achieve that, while a high efficiency and a low hysteresis is maintained, the weight can be reduced, it is suggested according to the invention to use a fork-shaped pivoting lever in the case of which two legs extend or fork from the end region of its actuating arm, the semicircular pivot bearing as well as the bearing of the eccentric each being formed by corresponding pairs of bearings in the end regions of the legs.
