Patent number: 11608865Abstract: A brake caliper, in particular a sliding caliper, of a disc brake of a commercial vehicle includes a brake application portion, which extends around a holding space for holding at least one brake application device; a caliper back; two tension struts, which run substantially parallel and at a distance to one another and connect the brake application portion to the caliper back; a closure cover, which closes the holding space; and an interface for mounting a pivotable brake lever on the side of the brake application portion facing away from the closure cover. A mounting opening for inserting and removing brake pads is formed between the brake application portion, the caliper back and the tension struts. The ratio of the length of the brake application portion to the sum of the length of the brake application portion and the length of a tension strut is between 0.4 and 0.3.Type: GrantFiled: August 26, 2019Date of Patent: March 21, 2023Assignee: KNORR-BREMSE Systeme fuer Nutzfahrzeuge GmbHInventors: Tobias Fischl, Wolfgang Pritz

Patent number: 11359684Abstract: 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.Type: GrantFiled: November 20, 2018Date of Patent: June 14, 2022Assignee: KNORR-BREMSE Systeme fuer Nutzfahrzeuge GmbHInventors: Tobias Fischl, Wolfgang Pritz, Andreas Petschke, Josef Schropp, Julian Cato Dahlenburg, Markus Bartel

Patent number: 11111974Abstract: 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.Type: GrantFiled: September 13, 2019Date of Patent: September 7, 2021Assignee: KNORR-BREMSE Systeme fuer Nutzfahrzeuge GmbHInventors: Tobias Fischl, Josef Schropp, Andreas Petschke
