Side-Blown Wheel Cooling for Selective Vehicle Brake Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle testing devices are limited in their ability to selectively cool specific parts of a tire-wheel assembly, such as brakes, and struggle to improve cooling efficiency due to a fixed air outlet configuration.
Innovation Solution
A vehicle testing device with a cooling system that allows air to be blown from the side of the test piece, utilizing a wind direction adjuster to target specific areas like tire, wheel, brake pads, or brake disks, and an air volume controller to adjust airflow based on vehicle speed and temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If air is blown from a fixed air outlet at the floor ahead of the roller, then the cooling device structure is simple, but it is difficult to selectively cool specific parts such as brakes and cooling efficiency is limited
Solution Approach 1:
The air outlet is made movable along the roller's axial direction, allowing dynamic adjustment of the air outlet position to target different parts of the tire-wheel assembly. This dynamic positioning capability enables selective cooling of specific components without requiring multiple fixed air outlets, thus improving adaptability while controlling device complexity.
Solution Approach 2:
The movable air outlet serves multiple cooling functions by being positioned at different locations along the roller's axial direction. A single air outlet structure can cool various parts including the tire, wheel, and brake components by adjusting its position, replacing the need for multiple dedicated air outlets for each component.
2Productivity
If air is blown directly to the tire-wheel assembly, then the cooling path is direct, but the contact area with the assembly is limited and overall cooling efficiency is reduced
Solution Approach 1:
The cooling approach transitions from direct axial blowing to side-direction blowing. By positioning the air outlet to blow air from the side toward the wheel accommodation space, the cooling air can wrap around and contact multiple surfaces of the tire-wheel assembly simultaneously, dramatically increasing the effective contact area and improving overall cooling efficiency.
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
Enables flexible cooling of specific parts, improving efficiency by allowing direct air circulation within the wheel accommodation space, effectively cooling the entire tire-wheel assembly more efficiently than previous systems.
Implementation Method 1
a cooling device that sends air from a side of the test piece toward at least a part of the test piece in order to cool the test piece placed on the rotating body
