Brake Lever With Pivotable Coupling For Smooth Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brakes experience fluctuating braking forces due to abrupt generation of tangential force when the brake pad engages with the brake disk, making it difficult to regulate the braking force and impairing vehicle comfort.
Innovation Solution
A brake design featuring a pivotable coupling part between the brake-disk-side and actuator-side parts, which increases the spacing between these components when the tangential force acts, allowing the braking force to be gradually increased, eliminating discontinuities in the braking force curve and enabling easier control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the brake pad comes into contact with the brake disk, then the tangential force is generated to boost the braking force, but the braking force becomes fluctuating and difficult to regulate
Solution Approach 1:
The coupling part is designed to be pivotable relative to the brake-disk-side part and/or actuator-side part, transforming the rigid connection into a dynamic one. This allows the spacing between brake-disk-side part and actuator-side part to change gradually during brake engagement, converting the abrupt force generation into a progressive process that eliminates fluctuations and improves regulability
2Force
If the lever diverts the tangential force to boost the braking force, then the braking force increases significantly, but the abrupt boosting causes discontinuity in the braking force curve
Solution Approach 1:
The pivotable coupling part introduces a dynamic element that gradually changes the spacing between brake-disk-side part and actuator-side part during engagement. This progressive spacing change smooths out the abrupt boosting effect of the lever, eliminating discontinuities in the braking force curve and ensuring continuous, stable force application
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
The design allows for smoother regulation of braking force, reducing abrupt changes and improving vehicle comfort by ensuring a continuous and controlled braking force application.
Implementation Method 1
the coupling part being pivotable relative to the brake-disk-side part and/or relative to the actuator-side part
Implementation Method 2
the lever engages on the coupling part, such that when the tangential force acts on the lever, the lever pivots the coupling part relative to the brake-disk-side part and/or actuator-side part
Implementation Method 3
the brake pad comes into contact with the brake disk, a tangential force is generated because the rotating brake disk drags the brake pad with it

AI summary
A brake includes a brake shoe, an actuating element for pressing the brake shoe against a brake disc, and at least one lever disposed such that it increases the braking force applied by the brake shoe to the brake disc by deflecting a tangential force acting on the brake shoe during braking. The actuating element comprises at least one brake disc side part, an actuator side part, and a coupling part disposed between the brake disc side part and the actuator side part, wherein the coupling part can be pivoted relative to the brake disc side part and/or the actuator side part.
