Abstract

An application device for a compressed-air-operated disc brake with a turn lever, an eccentric and two parallel male-threaded adjusting spindles, each of which acts via a pressure member on a brake pad and which are coupled together rotationally fixed via a synchronising device, in which an axially movable adjusting device is arranged to be integral in rotation in at least one adjusting spindle and, at every actuation of the turn lever, exerts an adjusting torque on the appropriate adjusting spindle which the synchronising device transmits to an adjuster or an actuator in the other adjusting spindle. The synchronising device is a shaft running in the region of the axis of the eccentric having a bevel gear on each face which meshes with a corresponding bevel gear of the adjusting device or the actuator.

Dependent claims

A compressed-air-operated disc brake comprising:

a caliper having a pair of brakes on each side of a brake disc;
an application device on a first side of said brake disk operable connected to
a transverse member which is slidably guided with respect to the brake disc by a lever which swivels about an axis of rotation parallel to the plane of the brake disc;
first and second adjusting spindle adjustably screwed to the transverse member and acting upon a brake shoe which is displaceably disposed with respect to the brake disc in the caliper on the first side;
at least one adjusting device applying adjustment torque to adjustably rotate the first adjusting spindle during each actuation of the lever;
a synchronizing device operably interconnecting the rotation of the first and second adjusting spindles;
and
said synchronizing device including a shaft parallel to the lever's axis of rotation and adjacent to the connection of the lever and the transverse member and a first bevel gear on each end of the shaft meshing with a corresponding second bevel gear operably connected to the adjusting spindles to form an angle drive.
