Motorcycle Balance Control via Adjustable Catenary Tension

The patent applies the dynamics principle by making the swingarm's extension direction adjustable relative to the load transfer direction. Instead of fixing the swingarm at a predetermined angle, the system allows dynamic adjustment of the catenary tension angle through movable connection elements, enabling the balance control system to adapt to varying load conditions rather than being limited to predetermined values.

The patent implements parameter changes by modifying the catenary tension angle as a variable parameter. The connection between the swingarm and chain is made adjustable, allowing the angle between the swingarm extension direction and the chain tension direction to be changed based on load conditions, thus maintaining optimal balance control across different operating scenarios.

The patent replaces the electronic control system with a mechanical adjustment mechanism. Instead of using electronically-controlled dampers that require sensors, controllers, and power sources, the invention uses a purely mechanical system with adjustable connection elements that modify the catenary tension angle through mechanical means, thereby achieving balance control while eliminating electronic components and associated costs.

The patent implements self-service by designing a mechanical system that automatically adjusts the catenary tension angle based on suspension compression and load transfer conditions. The adjustment mechanism responds passively to mechanical inputs from the suspension system, eliminating the need for external electronic control, power supply, or complex sensing systems.

The patent applies dynamics by transforming the fixed swingarm configuration into an adjustable one. The connection between the swingarm and the chain is made movable, allowing the swingarm's extension direction to be dynamically adjusted relative to the load transfer direction, thus maintaining balance stability across varying load conditions rather than being fixed for a single predetermined condition.

The patent implements universality by designing the swingarm connection system to serve multiple functions: it maintains the primary suspension function while simultaneously providing adjustable balance control for various load conditions. The adjustable connection element allows the same mechanical structure to adapt to different operating scenarios, making the system universally applicable across diverse riding conditions.
