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
