Axle Bracket Airflow Structure for Front Brake Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake cooling techniques for saddle-riding vehicles, which rely on air ducts around the axle bracket, are limited by the type of vehicle and can be inefficient due to obstruction by the axle bracket itself.
Innovation Solution
Incorporating a first introduction portion in the coupling portion of the axle bracket that guides traveling wind from the front to the rear, ensuring the path intersects with the brake attachment portion, allowing efficient airflow to the brake.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an air duct is added around the axle bracket to cool the brake, then brake cooling efficiency is improved, but device complexity and structural constraints increase
Solution Approach 1:
The patent merges the air duct function with the axle bracket structure by forming the introduction portion directly as part of the coupling portion. The coupling portion is designed with a through-hole that serves as the air duct, eliminating the need for separate air duct components and reducing overall device complexity while maintaining brake cooling functionality
Solution Approach 2:
The coupling portion serves multiple functions: it couples the damper to the axle, provides structural support, and acts as an air duct for brake cooling through its introduction portion. This multi-functionality reduces the number of separate components needed and simplifies the overall brake cooling system
2Strength
If the axle bracket is designed to couple damper to axle, then structural integrity is improved, but brake cooling efficiency deteriorates due to wind blockage
Solution Approach 1:
The coupling portion is segmented to include a through-hole (introduction portion) that divides the solid structure into functional zones: the outer shell maintains structural strength for damper-axle coupling, while the internal through-hole creates a fluid passage for air flow. This segmentation allows the same component to fulfill both structural and cooling functions simultaneously
Solution Approach 2:
The introduction portion acts as an intermediary element within the coupling portion that mediates between the structural requirement (solid coupling) and the cooling requirement (air flow passage). The through-hole serves as a mediator that allows air to pass through the coupling portion to reach the brake without compromising the coupling portion's structural integrity

Function Achieved in This Case
This solution enables effective brake cooling without the need for additional air ducts, improving cooling efficiency while maintaining the structural integrity and design flexibility of the axle bracket.
Implementation Method 1
at least the coupling portion includes a first introduction portion capable of guiding a traveling wind from a front of the coupling portion to a rear of the coupling portion
Implementation Method 2
