  • Publication number: 20230375050
    Abstract: Disclosed is a brake application mechanism for a disc brake in a utility vehicle, having a pivotable brake lever that is supported on an inner wall of a brake caliper and, indirectly, on a bridge which is movably disposed in the brake caliper and which supports at least one brake pad, wherefor an axially and radially secured antifriction roller is disposed between the brake lever and the bridge. The disclosed brake application mechanism is designed such that the antifriction roller rests on the bridge in such a way as to be prevented from rotating and sliding.

  • Patent number: 11359684
    Abstract: A disc brake for a commercial vehicle is provided. The disc brake includes a brake caliper, preferably in the form of a sliding caliper, straddling a brake disc, being arranged on a fixed backing plate, and having an application device for applying the brake. The disk brake also includes two brake pads, each having a pad carrier and an affixed friction pad, and each being inserted into a pad shaft of the backing plate. The brake caliper has a central caliper opening over the disc brake. A hold-down bar is provided, designed in such a way that, of the two brake pads, it radially secures only the reaction-side brake pad in its lining shaft in the backing plate. The hold-down bar is held on the brake caliper by its end facing away from the brake pad. Additionally, the application-side brake pad is radially interlockingly secured in its pad shaft in the backing plate.

  • Publication number: 20220163077
    Abstract: An electrically or pneumatically activated disc brake for a commercial vehicle includes: a brake disc having a preferred rotating direction; a brake carrier; a brake caliper guided so as to be displaceable on the brake carrier; a tensioning-side brake pad and a reaction-side brake pad which, in a tensioning-side pad take-up and in a reaction-side pad take-up, are disposed so as to be displaceable parallel to a brake disc rotation axis; and a tensioning device which has a single compression piston with a central axis and which on an end facing the tensioning-side brake pad has a compression piece which by way of a compression face acts on a corresponding counter bearing face of the tensioning-side brake pad such that, when tensioning the brake, an effective area is configured between the compression face and the counter bearing face.

  • Patent number: 11111974
    Abstract: A brake carrier for a disc brake of a commercial vehicle has an attachment region for fixing on a vehicle axis and at least one pad shaft for receiving and supporting at least one brake pad. The pad shaft is formed by way of an inlet-side carrier horn, an outlet-side carrier horn and a bridge which connects the inlet-side carrier horn and the outlet-side carrier horn. Regions of the bridge which adjoin the carrier horns form bearing surfaces for radially supporting the at least one brake pad. The respective guide contours for guiding the brake pad into a push-in position are arranged to the side of the pad shaft on a side surface of the carrier horns, in which push-in position the brake pad can be pushed axially with respect to the vehicle axle into the pad shaft between the carrier horns.

  • Publication number: 20210206355
    Abstract: A disc brake for a utility vehicle includes a brake caliper, designed as a sliding caliper and engaging over a brake disc, which is secured to a stationary brake carrier. Two brake pads, which are arranged in the brake caliper, can move inversely and have a respective pad carrier plate and a friction lining secured thereon, of which an action-side or application-side brake pad can be pressed against the brake disc by an application device via at least one brake piston. The brake pads are each accommodated in a pad housing of the stationary brake carrier, wherein the pad housing is formed by two opposing brake carrier horns and a longitudinal connector connecting the brake carrier horns. At least one of the brake pads is assigned a pad return device, with which the at least one brake pad can be returned after a brake-dependent shifting and releasing of the brake.

  • Patent number: 10851857
    Abstract: A disc brake for utility vehicles includes a brake disc, a brake caliper spanning the brake disc, a brake carrier, and an application-side brake pad and a reaction-side brake pad, of which at least the application-side brake lining is accommodated in a lining slot of the brake carrier. The brake caliper houses a brake application device having a single pressure plunger arranged to exert a brake application force on the application-side brake lining via a pressure plate. The brake is configured with one or both of an operative plane of the pressure plate being offset in the direction of the exit side at a distance from a plane of symmetry of the disc brake, and a bevel on the exit side of at least the application-side brake lining.
