Abstract

A brake caliper of a disk brake for a utility vehicle is provided. The brake caliper includes tension braces which are arranged substantially parallel and at a distance from each other, straddling a brake disk and connecting receptacles for functional parts arranged on both sides of the brake disk. One receptacle forms a caliper back and the other receptacle forms a housing having a lever dome formed thereon. The brake caliper includes at least one replaceable service-related wear protection element fastened to areas of potential wear during in-service use of the brake caliper, such as at the lower side of the leading tension brace and at least partially around the lever dome.

Claims

1. A brake caliper of a disk brake for a utility vehicle, comprising:

receptacles for functional parts arranged to be located on opposite sides of a brake disk when the brake caliper is mounted on the utility vehicle, wherein a first one of the receptacles is a caliper back and a second one of the receptacles is a housing having a lever dome;

tension braces connecting the receptacles, the tension braces being arranged substantially parallel and at a distance from one another and bridging over an outer radius of the brake disk when the brake caliper is mounted on the utility vehicle; and

at least one replaceable protective element located at at least one area of service-related wear on the brake caliper,

wherein

the at least one replaceable protective element includes a tension brace protector arranged on an underside of the tension brace facing away from the lever dome, and

the at least one replaceable protective element includes a lever dome protector.

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

the tension brace protector is secured on a one of the tension braces located at a leading edge of the brake caliper relative to a forward rotation direction of the brake disk.

3. The brake caliper as claimed in claim 2, wherein

the tension brace protector projects outward from the brake caliper beyond the one of the tension braces.

4. The brake caliper as claimed in claim 3, wherein

the tension brace protector is stirrup-shaped, having a bar and two angled lugs, the two angled lugs including holes for passage of fasteners.

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

the lever dome protector is horseshoe-shaped, having two angled lugs with holes for passage of fasteners.

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

the lever dome protector is connected to a flange of the lever dome.

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

the lever dome protector rests on the housing and at least partially surrounds the lever dome.

8. The brake caliper as claimed in claim 1, wherein

the lever dome protector has a height equal to or greater than the height of the lever dome.
