This project focused on designing the rear suspension linkage system to control wheel motion and damper response. The objective was to achieve a target motion ratio while maintaining alignment, packaging constraints, and manufacturability. 

The linkage needed to deliver a specific leverage curve across suspension travel while fitting inside the frame and swing arm envelope. Poor pivot placement would create side loading, interference, or inconsistent damping response. 

I defined link lengths and rocker geometry using hand calculations and motion ratio relationships before refining geometry in CAD. Pivot positions were iterated to achieve the desired leverage curve while maintaining alignment between bearings.

Full travel clearance checks were performed to verify no interference between links, shock body, frame members, or fasteners.

Manufacturing and Integration
Interfaces were refined for standard bearings and fasteners. Mounting faces were aligned to reduce side loading and simplify assembly. Geometry supported fabrication using realistic machining methods.

The final linkage achieved target motion ratios, maintained alignment through travel, and integrated cleanly with the swing arm and chassis.
