Abstract

A functional unit is provided for adjusting a brake pad of a disc brake, having the following function parts: a guide rail, two adjusting spindles, arranged parallel to and spaced apart from each other in the guide rail and held in an axially moveable manner, and a synchronization device for synchronously adjusting the adjusting spindles, wherein the functional parts are pre-mounted into one assembly.

First claim

What is claimed is:

1. An apparatus for adjusting a brake pad of a disc brake, comprising:
a guide rail;
two adjusting spindles arranged parallel to and at a given distance from one other in the guide rail, the two adjusting spindles being held in an axially moveable manner; and
a synchronizing device configured for synchronous adjustment of the adjusting spindles, wherein
the guide rail, the two adjusting spindles, and the synchronizing device are functional parts preassembled into a modular unit,
the two adjusting spindles are synchronized with one another during preassembly to form the modular unit,
a tamper-proof marking is arranged in an adjoining region of two functional parts of the modular unit that are moveable relative to one another, and
the synchronizing device includes a traction mechanism consisting of two drive wheels held in a rotationally locked but axially displaceable manner on an associated adjusting spindle, such that the traction mechanism engages in a positive relocking manner into an external toothing system of the two drive wheels.

2. The apparatus according to claim 1 , wherein the modular unit further comprises a closure plate having, in each case, one folding bellows assigned to a respective adjusting spindle, the folding bellows sealing a passage opening in the closure plate through which the adjusting spindle protrudes.

3. The apparatus according to claim 1 , wherein the tamper-proof marking is a seal.

4. The apparatus according to claim 1 , wherein the traction mechanism is selected from the group consisting of a link chain, a toothed belt, and a string of beads.

5. The apparatus according to claim 2 , wherein in the preassembled modular unit, the closure plate and the guide rail are coupled to one another by a seal.

6. The apparatus according to claim 2 , wherein tamper-proof marking is arranged between the closure plate and the guide rail.
