AI Technical Summary

Technical Problem

Conventional drum brake systems are heavy, leading to high unsprung mass and increased energy consumption, and require complex brake pad replacement procedures that necessitate removal of the entire vehicle wheel.

Method used

A drum brake system with wear elements mounted on the inside of the brake drum, utilizing a positive-locking connection to secure them radially and tangentially, allowing easy replacement without disassembling the wheel, and incorporating a thinner-walled brake drum design to reduce weight and inertia.

Benefits of technology

The system achieves a lighter, more energy-efficient brake with simplified maintenance by reducing the brake drum's weight and unsprung mass, improving vehicle acceleration and extending the service life of brake components.

Abstract

The present invention relates to a braking system, a drum brake unit and a method for maintaining a drum brake unit, the braking system comprising a brake drum and at least two wear elements, wherein the wear elements are designed to come into contact with an element-side connecting section on a drum-side connecting section of the brake drum, wherein the element-side connecting section and the drum-side connecting section engage in such a way that the engagement prevents a displacement of the wear element relative to the brake drum radially to an axis of rotation of the brake drum.
