Brake Disc Shielding Device Tilted Ribs Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake disk shielding devices compromise between cooling performance and protection, as they either hinder heat dissipation or allow dirt ingress through openings, leading to reduced brake durability and wear.
Innovation Solution
The brake disk shielding device features tilted, slit-shaped air outlet openings with protruding ribs that deflect air flows perpendicular to the airflow direction, enhancing heat convection while preventing dirt ingress by directing air outward and creating a negative pressure area for effective cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the shielding plate is provided with straight opening slots to improve heat dissipation, then cooling performance is improved, but protection against dirt ingress deteriorates
Solution Approach 1:
The opening slots are segmented into multiple individual slots arranged in a circular pattern, with each slot being narrow and radially oriented. This segmentation allows sufficient total opening area for heat dissipation while maintaining narrow individual openings that prevent dirt ingress into the brake system
Solution Approach 2:
The opening slots are arranged in a circular pattern around the brake disc, utilizing the circumferential dimension. This circular arrangement maximizes the total cooling area while keeping each individual slot narrow and radially oriented, thereby preventing dirt ingress while maintaining effective heat dissipation
2Object-affected harmful factors
If the shielding plate covers the brake disc completely to protect against contamination, then protection level is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The shielding plate features localized openings distributed around its circumference, creating different local properties: most areas provide protection while the opening slots provide heat dissipation. The narrow radial orientation of each slot provides protection against tangential dirt ingress while allowing radial heat dissipation

AI summary
A brake disc shielding device comprises at least two air outlet openings (11) in a side surface (13) of the brake disc shielding device (10), wherein the air outlet openings (11) each have a rib (12) projecting from the side surface (13), wherein the ribs are arranged tilted to a radial direction of the side surface (13) such that the ribs (12) are arranged substantially perpendicular to an airflow direction (L) of an airflow deflected by a rotational movement of the brake disc during driving operation.
