Motor Vehicle Brake Cooling Flow Guide and Paneling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle wheel suspension designs face aerodynamic disadvantages and restricted brake cooling, as previous solutions either compromise aerodynamics or limit cooling efficiency when attempting to direct cooling air to wheel carriers or brakes.
Innovation Solution
The design incorporates separate paneling parts with recesses for air flow, combined with a flow guide element connected to the underfloor or underfloor paneling, which divides the air flow into two channels to efficiently cool both regions of the brake, while maintaining optimal aerodynamics by attaching to both longitudinal and transverse links of the wheel suspension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling air is directed to the brake through paneling parts with recesses, then brake cooling efficiency is improved, but aerodynamic performance deteriorates
Solution Approach 1:
The paneling part is divided into multiple recesses (first recess and second recess) that separately direct cooling air to different regions of the brake. This segmentation allows optimized airflow paths for cooling while maintaining aerodynamic surfaces, as each recess can be strategically positioned and shaped to serve its specific cooling function without compromising overall aerodynamics
Solution Approach 2:
Different regions of the brake are provided with cooling air through locally optimized recesses in the paneling part. The first recess directs air to a first region of the brake while the second recess directs air to a second region, allowing each area to receive cooling air in the most efficient manner while the surrounding paneling maintains aerodynamic quality
2Device complexity
If a single air flow channel is used for brake cooling, then device complexity is reduced, but cooling coverage of different brake regions is insufficient
Solution Approach 1:
The air flow channel system is segmented into multiple recesses (first recess and second recess) in the paneling part, each providing cooling air to different regions of the brake. This segmentation enables comprehensive cooling coverage of the entire brake assembly while maintaining a relatively simple integrated paneling structure without requiring complex external ducting
Solution Approach 2:
The paneling part serves multiple functions simultaneously: it provides structural coverage for the wheel suspension components, maintains aerodynamic performance, and distributes cooling air to multiple regions of the brake through its integrated recesses. This multi-functionality achieves comprehensive cooling without proportionally increasing device complexity

Function Achieved in This Case
This solution enhances both aerodynamics and brake cooling efficiency by allowing divided air flow to reach different regions of the brake, ensuring effective cooling with minimal adverse effect on the vehicle's aerodynamics.
Implementation Method 1
the flow guide element, which, together with the respective separate paneling part, divides up the air flow into: a first air flow, which can be fed, upstream of the recess, via a first flow channel of the respective separate paneling part to a first region of the respective brake, and into a second air flow, which can be fed via the recess of the respective separate paneling part and via a second flow channel of the respective separate paneling part to a second region of the respective brake
Implementation Method 2
each of the respective paneling parts having a recess via which air can be fed for cooling purposes to a brake which corresponds to a respective one of the wheels
