A disc brake for a commercial vehicle has a caliper that straddles a brake disc. The caliper is mounted on a brake carrier on the vehicle side by way of two connecting bearings in an axially displaceable manner in relation to the brake disc. The connecting bearings each include a guide bar that is securely connected to the brake carrier and guided in a slide bearing of the caliper for the axial displacement thereof. At least one connecting bearing is provided with a radially elastic damping bushing, which at least surrounds the guide bar in regions and has grooves that are laterally delimited by ribs. The disc brake is designed such that the damping bushing has a progressive damping behavior in the radial loading direction.

Disc brake for a commercial vehicle

A bellows arrangement on a guide bar of a disc brake, particularly of a commercial vehicle, has an end of the bellows comprising a sealing ring, particularly a quad ring, lying in a circumferential groove of the guide bar. The bellows is pressed into the groove by a retaining ring placed thereon, and is designed so that an air passage can form in the contact area of the sealing ring at the base of the groove, reducing the volume enclosed by the bellows and the guide bar. To this end, the contact shoulder formed on the retaining ring is circumferentially interrupted in segments.

A brake pad holder of a disc brake, in particular for a commercial vehicle is provided, wherein brake pads assigned to both sides of a brake disc are held by a respective pad-holding spring in a spring-loaded manner in a pad shaft of a positionally fixed brake anchor plate or of a brake caliper. A pad-holding clip, which extends in the axial direction of the brake disc and is fastened to the brake caliper, is supported on the brake pads. The brake pad holder is designed such that the pad-holding clip has at least one limb which extends approximately radially with respect to the brake disc and enters into a recess of at least one brake pad.

A disc brake, particularly for a commercial vehicle, includes a brake caliper, which is provided with a brake disc and fixed to a brake carrier by two fastening elements such that it can be axially displaced in relation to the brake disc. The fastening elements each include a guide spar, which is connected to the brake carrier in a fixed manner. For the axial displacement of the brake caliper, one of the guide spars is guided in a plain bearing designed as a movable bearing and the other in a plain bearing designed as fixed bearing such that the guide spar of the fixed bearing includes an elastically deformable section in the radial direction on the outer circumference. The associated bearing rests against the deformable section at least in some sections.
