Front-Wheel Air Conveyor Layout for Stable Motorcycle Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air cooling systems in motorcycles, particularly racing ones, face overheating issues due to variability in airflow during braking and acceleration, leading to inefficient engine cooling and increased aerodynamic drag.
Innovation Solution
A damped support system with an air conveyor that surrounds the front wheel, featuring an inlet mouth positioned to capture air independently of the wheel's movement, ensuring consistent airflow to the radiator, and minimizing interference with steering and aerodynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the air cooling system mouth is positioned under the cowl and partially covered by the front wheel and suspension, then the aerodynamic drag is reduced, but the engine cooling performance becomes unstable during braking and acceleration
Solution Approach 1:
The air cooling system is divided into two independent air conveyors: one positioned above the front wheel and another below it. This segmentation allows each conveyor to independently capture airflow from different regions, ensuring that the total cooling airflow remains stable even when the suspension position changes during braking or acceleration.
Solution Approach 2:
The air conveyors are positioned in both vertical and horizontal dimensions relative to the front wheel. By distributing the air intake openings above and below the wheel at different horizontal positions, the system captures airflow from multiple spatial dimensions, compensating for position changes during vehicle operation.
2Reliability
If the radiators are oversized to guarantee adequate cooling during all conditions, then the cooling performance is sufficient, but the overall dimensions, weights and costs increase
Solution Approach 1:
The air conveyors are designed with flexible positioning relative to the front wheel, allowing them to adapt to changes in wheel position during braking and acceleration. This dynamic adaptation ensures consistent cooling airflow without requiring oversized radiators, thereby reducing the overall system weight.
3Reliability
If the air conveyor is shaped to surround the front wheel, then the airflow to the radiator is stabilized, but the device complexity increases
Solution Approach 1:
The air conveyor system is segmented into multiple independent air conveyors positioned at different locations around the front wheel. Each conveyor has a relatively simple structure with air intake and outlet openings, but collectively they achieve stable airflow delivery without requiring a single complex surrounding structure.
