Caliper Brake Mounting Bracket Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Caliper brakes suffer from uneven wear and noise due to 'drooping' and twisting caused by inadequate mounting mechanisms, leading to inconsistent braking forces and wear patterns.
Innovation Solution
A centrally mounted bracket with spacers extending from both sides to stabilize the mounting bracket, preventing deflection and twisting, and utilizing a combination of bolts and nuts with spacers to secure the stator assemblies and stationary plate, ensuring even distribution of braking forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If minimal clearance is provided between the mounting bracket and brake components, then the brake assembly has freedom of motion relative to the mounting bracket, but this causes the brake assembly to droop and results in uneven brake pad wear and high pitch noise
Solution Approach 1:
The patent introduces spacers as intermediary elements between the mounting bracket and the brake components (stator assemblies and stationary plate). These spacers act as mediators that maintain proper clearance while preventing direct contact that would cause drooping. The spacers distribute forces evenly and maintain stable positioning, thereby eliminating the drooping issue and ensuring uniform brake pad wear while preserving necessary freedom of motion.
2Device complexity
If the mounting bracket is located on one side of the brake assembly, then it simplifies the mounting structure, but this causes twisting of the brake assembly during braking due to dynamic rotating forces
Solution Approach 1:
The patent employs asymmetric mounting by positioning the mounting bracket on one side of the brake assembly rather than symmetrically. This asymmetric configuration, combined with strategically placed spacers, creates a stable mounting structure that resists twisting forces during braking. The spacers are positioned to counterbalance the dynamic rotating forces, preventing the twisting and untwisting motion that would otherwise occur with asymmetric mounting.
3Reliability
If the mounting bracket is centrally mounted with spacers, then twisting and drooping are prevented, but the device complexity increases due to additional components
Solution Approach 1:
The patent segments the mounting mechanism into distinct functional components: the central mounting bracket, multiple spacers (including inner and outer spacers), and mounting bolts. This segmentation allows each component to perform its specific function - the bracket provides central mounting, the spacers maintain clearance and distribute forces, and the bolts secure the assembly. While this increases the number of parts, it significantly improves reliability by eliminating drooping and twisting, ensuring consistent brake performance.

AI summary
A caliper brake including a mounting bracket adapted to be secured to a vehicle. The mounting bracket includes a pair of laterally spaced holes, and a mounting bolt is received through each hole. Each bolt includes a head and a threaded portion on opposing ends, and a nut is received on each threaded portion. An inner spacer extends between the mounting bracket and the nut on each bolt, and an outer spacer extends between the mounting bracket and the head on each bolt.
