Brake Caliper Elastic Mounting for Disc Tilting Compensation
Solution Overview
Problem
The existing brake caliper structures for straddle seat off-road vehicles face challenges in smoothly accommodating the tilting of the brake disc and ensuring proper movement of the brake caliper relative to the stationary bracket, particularly when the wheel tilts due to lateral forces.
Innovation Solution
A brake caliper structure with a fixed part mounted to the knuckle, a movable part, and connecting portions that include a guide hole and an elastic member, allowing the movable part to slide and absorb tilting, ensuring smooth movement and effective clamping of the brake disc.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the brake caliper is elastically supported by elastic bushings to accommodate brake disc tilting, then the brake caliper can take up tilting of the brake disc, but the movement of the brake caliper relative to the bracket may become unsmooth
Solution Approach 1:
The connecting portion is divided into two distinct functional elements: a guide hole for directional guidance and an elastic member for tilting accommodation. This segmentation allows each element to specialize in its function - the guide hole ensures smooth linear movement while the elastic member handles tilting absorption, resolving the contradiction between adaptability and operational smoothness.
Solution Approach 2:
The guide hole acts as an intermediary structure that mediates between the elastic member and the brake caliper body. It provides a constrained path for the elastic member to move, ensuring that the tilting accommodation function does not compromise the smoothness of the caliper's linear movement relative to the bracket.
2Stability of the object's composition
If the brake caliper is rigidly mounted to the knuckle, then the structure is simple and stable, but it cannot accommodate the tilting of the brake disc
Solution Approach 1:
The mounting structure transitions from a rigid static connection to a dynamic semi-rigid connection. The elastic member introduces controlled flexibility that allows the brake caliper to adapt to brake disc tilting while maintaining overall structural stability. This dynamic characteristic enables the system to maintain stability under normal conditions while adapting to tilting variations.
Solution Approach 2:
The connecting portion changes the rigidity parameter of the mounting structure by introducing an elastic member. This parameter change allows the structure to maintain sufficient stiffness for stability while incorporating enough flexibility to accommodate tilting, resolving the contradiction between structural stability and tilting adaptability.
3Device complexity
If the guide hole is formed without any elastic member, then the structure is simple, but it cannot take up the tilting of the brake disc
Solution Approach 1:
The elastic member serves as an intermediary element inserted into the guide hole structure. This intermediary component adds the necessary tilting absorption capability without fundamentally changing the overall guide hole structure, maintaining relative simplicity while enabling adaptability to brake disc tilting.
Solution Approach 2:
The connecting portion combines rigid material (guide hole structure) with elastic material (elastic member) to create a composite functional element. This composite structure integrates the simplicity of the rigid guide hole with the tilting absorption capability of the elastic member, achieving both structural simplicity and adaptability.
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 arrangement effectively takes up the tilting of the brake disc, ensuring the movable part follows the disc's movement, maintaining proper friction pad positioning and enhancing brake performance by allowing smooth guiding of the caliper relative to the bracket.
Implementation Method 1
an elastic member disposed between the movable part and the fixed pin... the elastic member effectively takes up or absorbs the tilting of the brake disc
Implementation Method 2
a slide pin connected to the movable part and slidably received in the hole of the fixed part... the movement of the movable part relative to the fixed part can be effectively guided as the slide pin slides in an axial direction within the guide hole

AI summary
A brake caliper structure of a straddle seat off-load vehicle includes a brake caliper having a caliper bracket, a caliper assembly connected to the caliper bracket by two connecting portions so that the caliper assembly can move relative to the caliper bracket to clamp a brake disc. One connecting portion includes a slide pin connected to the caliper assembly and slidably received in a guide hole in the caliper bracket for effectively guiding movement of the caliper assembly relative to the caliper bracket, and the other connecting portion includes a connecting screw as a fixed pin secured to the caliper bracket, and a rubber bushing as an elastic member disposed between the caliper assembly and the fixed pin for taking up the tilting of the brake disc.
