Brake Lining Springs Prevent Material Digging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disc brake pads in commercial vehicles experience material digging into the carrier due to vibrations, leading to noise and increased wear, which existing designs fail to fully mitigate.
Innovation Solution
Incorporating at least two pad revolving springs that exert compressive force on the peripheral surface of the brake pad carrier, covering corner areas, in combination with a pad retaining spring, made of hard corrosion-resistant materials like steel to reduce digging and enhance resilience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pad retaining spring is used to fix the brake pad within the brake pad carrier, then the brake pad is secured and tolerances are compensated, but the brake material digs into the brake pad carrier due to vibrations causing noise and wear
Solution Approach 1:
The retaining mechanism is divided into two separate spring systems: a pad retaining spring for securing the brake pad and compensating tolerances, and pad revolving springs for preventing material digging. This segmentation allows each spring to specialize in its specific function without compromising the other.
Solution Approach 2:
Different regions of the brake pad carrier are treated differently: corner areas are covered by pad revolving springs to prevent material digging, while the overall pad position is controlled by the pad retaining spring. This local differentiation addresses the harmful digging effect specifically where it occurs most.
2Object-generated harmful factors
If the brake pad is firmly fixed to reduce vibrations, then noise is reduced, but wear on moving components increases
Solution Approach 1:
The pad revolving springs are positioned in advance to cover corner areas of the brake pad carrier, providing cushioning against the brake material before digging can occur. This preventive cushioning reduces both noise from vibrations and wear on moving components throughout the service life.
3Reliability
If corrosion-resistant materials are used for the pad revolving springs, then corrosion protection is improved, but device complexity increases
Solution Approach 1:
The pad revolving springs are made from composite or alloy materials that combine corrosion resistance with the required mechanical properties. This allows the springs to provide both structural function and corrosion protection without requiring additional protective components that would increase complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration significantly reduces noise and wear by optimizing the mounting of brake components, preventing corrosion, and maintaining brake efficiency over the service life.
Implementation Method 1
at least two pad revolving springs (6, 7) acting on the pad carrier (2) and exerting a compressive force at least in sections on an outer peripheral surface of the brake lining
Implementation Method 2
The combination of the pad retaining spring and the pad revolving springs results in optimized resilient mounting in the brake carrier shaft and/or in the brake caliper shaft, which reduces wear on the components that move relative to one another and reduces noise

AI summary
The invention relates to a brake lining for a disc brake of a road vehicle, comprising a blade-type retaining spring (4) for the lining. The invention is characterised in that at least two peripheral lining springs (6, 7) are situated on each brake lining (2, 3), adjacent to the retaining spring (4), said springs exerting a compressive force on at least some sections of the periphery of the lining carrier (2) and being configured in such a way that they respectively cover an edge region of the brake lining carrier (2), the latter having at least two corner regions E1 and E2 and E3 and E4.
