Split Fuel Tank and Transverse Suspension for Motorcycle Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Two-wheeled vehicles, such as motorcycles, face challenges in preventing unwanted tip-overs and optimizing the placement of components to enhance stability and cargo carrying capacity while maintaining a low center of gravity.
Innovation Solution
The design includes a configuration of fuel storage tanks positioned forward to lower the center of gravity, a rear suspension system with a shock absorber and linkage that moves in a transverse plane, and an exhaust system that extends rearward but passes in front of the rear wheel, along with a tip-over prevention system using support members to prevent damage during unintended tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fuel storage tanks are positioned forward to lower the center of gravity, then stability is enhanced, but cargo carrying capacity is reduced
Solution Approach 1:
The fuel storage system is divided into multiple separate tanks (first fuel storage tank and second fuel storage tank) positioned at different locations. The first tank is positioned forward to lower the center of gravity and enhance stability, while the second tank is positioned rearward to maximize cargo carrying capacity by utilizing available space in the rear portion of the vehicle.
2Stability of the object's composition
If components are positioned to lower the center of gravity, then stability is enhanced, but device complexity increases
Solution Approach 1:
Multiple functions are combined into the swing arm assembly. The swing arm not only supports the rear wheel and provides suspension mounting but also serves as a structural element for positioning the exhaust system and rear fuel storage tank. This integration reduces the number of separate components and simplifies the overall system while achieving the desired center of gravity positioning.
3Object-affected harmful factors
If a tip-over prevention system is added, then damage during tip-overs is minimized, but device complexity increases
Solution Approach 1:
The tip-over prevention system utilizes the vehicle's existing structural components (swing arm, exhaust system, and frame) to provide passive support during tip-overs. The system does not require active control mechanisms, sensors, or additional power sources. Instead, the strategically positioned components naturally provide support forces when the vehicle tips, preventing damage through the vehicle's own structure.
