Abstract

A floating-caliper disc brake of a utility vehicle includes a brake disc, a brake carrier spanning the brake disc and having lining shafts arranged on both sides of the brake disc, a brake caliper overlapping the brake disc and movable relative to the brake carrier, brake linings arranged on both sides of the brake disc in a lining shaft of the brake carrier, and having a lining carrier plate and a friction lining attached thereto. An application-side brake lining can be pressed against the brake disc by an application device and a reaction-side brake lining can be pressed against the brake disc by a brake caliper back, by moving the brake caliper. The brake caliper can be reset by a resetting device along a wear adjustment path in an axial direction to the axis of rotation of the brake disc. With the same volume of the friction linings in the new condition, the friction lining thickness of the reaction-side brake lining is not the same as the friction lining thickness of the application-side brake lining ( 5 ).

First claim

What is claimed is:

1. A floating-caliper disc brake of a utility vehicle, comprising:
a brake disc;
a brake carrier spanning the brake disc having pad shafts arranged on both sides of the brake disc;
a brake caliper engaging over the brake disc that is displaceable relative to the brake carrier;
brake pads arranged on both sides of the brake disc in a respective pad shaft of the brake carrier, each brake pad having a pad carrier plate and a friction lining attached to the same,
wherein
an application-side brake pad is pressable against the brake disc via an application device and a reaction-side brake pad is pressable via a brake caliper back by shifting the brake caliper against the brake disc,
the brake caliper is adjustable by a wear adjustment travel axially to an axis of rotation of the brake disc via an adjustment device,
with an identical volume of the friction linings in a new condition, a friction lining thickness of the reaction-side brake pad is unequal to a friction lining thickness of the application-side brake pad,
the friction lining thickness of the reaction-side brake pad is less than the friction lining thickness of the application-side brake pad, and
a friction ring thickness of the brake disc on a side of the brake pad with the smaller friction lining thickness is less than a friction ring thickness of the brake disc on the side of the brake pad with the greater friction lining thickness.

2. The floating-caliper disc brake as claimed in claim 1 , wherein
a wear adjustment travel of the brake caliper is matched to the smaller friction lining thickness of the brake pad with the smaller friction lining thickness.

3. The floating-caliper disc brake as claimed in claim 1 , wherein
the brake disc is positioned in a brake disc opening of the brake carrier such that a distance of a friction ring surface of the brake disc facing the reaction-side pad shaft to the reaction-side pad shaft of the brake carrier is less than the distance of a friction ring surface of the brake disc facing the application-side pad shaft to the application-side pad shaft of the brake carrier.
