AI Technical Summary

Technical Problem

Existing disc brakes for commercial vehicles face challenges in managing material stresses and tilting due to high forces and temperature differences, leading to excessive wear and rattling, particularly in the bearing and force transmission areas between the brake caliper and brake pads.

Method used

A disc brake design featuring a pressure piece and a plate, where the plate is guided in radial and tangential directions by a brake carrier, with locking sections on the pressure piece engaging with corresponding engagement sections on the plate to prevent displacement, reducing material stresses and optimizing guidance, and allowing for a lightweight, low-maintenance assembly.

Benefits of technology

The design reduces local stress peaks, minimizes wear, and simplifies assembly by ensuring precise positioning of the plate and pressure piece, resulting in a stable and cost-effective disc brake system.

Abstract

A disk brake (1) having a pressure piece (2) and a plate (4); wherein the pressure piece has at least one bearing surface (24) against which the plate abuts in order to transmit a compressive force along a force axis; wherein the pressure piece has at least one first securing section (22A) which is designed and provided to be supported on a first engagement section (42A) formed on the plate; wherein the fact that the first securing section is supported on the first engagement section prevents displacement of the pressure piece relative to the plate along or parallel to a first securing direction; wherein the pressure piece has at least one second securing section (22B) spaced apart from the first securing section, which is designed and provided to be supported on a second engagement section (42A) formed on the plate; wherein the fact that the second securing section is supported on the second engagement section prevents displacement of the pressure piece relative to the plate along or parallel to a second securing direction.
