Abstract

A utility vehicle disk brake includes a vehicle-mounted brake carrier that partially surrounds a brake disk, and a brake caliper that is arranged on and partially covers the brake carrier. Sliding guides allow the brake caliper to slide relative to the brake carrier perpendicularly to a friction surface of the brake disk. A first one of the sliding guides is designed as a fixed bearing, and a second one of the sliding guides is designed as a floating bearing. At least the floating bearing is designed as a slotted guide having a guideway that runs in the sliding direction of the brake caliper as well as a first guiding element that is accommodated in the guideway.

Claims

1. A disc brake of a utility vehicle, comprising:

a brake carrier which is stationary on a vehicle side and partially surrounds a brake disc; and

a brake caliper which is arranged on the brake carrier and partially surrounds the latter, wherein

the brake caliper is displaceable relative to the brake carrier, perpendicularly to a friction surface of the brake disc, via sliding guides,

a first sliding guide of the sliding guides is formed as a fixed bearing and a second sliding guide of the sliding guides is formed as a floating bearing,

at least the floating bearing is formed as a sliding block guide having a guideway extending in the displacement direction of the brake caliper and a first guide element received in the guideway, and

the first guide element is arranged on the brake caliper so as to extend parallel to the friction surface of the brake disc, and the guideway is arranged on a part of the brake carrier.

2. The disc brake as claimed in claim 1, wherein

the first guide element extends perpendicularly to the direction of the longitudinal extent of the brake carrier.

3. The disc brake as claimed in claim 1, wherein

the guideway has sliding surfaces which are formed as mutually parallel-aligned inner surfaces of an elongated hole.

4. The disc brake as claimed in claim 1, wherein

the guideway has sliding surfaces which are formed as mutually parallel-aligned inner surfaces of an elongated groove which is open on one side in the sliding direction of the first guide element.

5. The disc brake as claimed in claim 1, wherein

the first guide element is formed as a bar or pin having a lateral surface serving as a sliding surface.

6. The disc brake as claimed in claim 5, wherein

a head piece reaching behind the guideway is integrally formed or mounted on an end face of the first guide element.

7. The disc brake as claimed in claim 1, wherein

the first guide element extends from a lower side of the brake caliper, which faces the brake carrier.
