Context
The goal of this project is to deepen my understanding of suspension systems as part of the suspension team in Thunderbike. The model explores how a double wishbone front suspension improves vehicle handling, ride comfort, and stability. It also demonstrates how material selection contributes to performance, using steel for structural strength, aluminum to reduce unsprung weight, and rubber to absorb vibration and reduce noise.
Approach
The suspension is built around a steel subframe that supports the upper and lower control arms, steering components, and coilover assembly. The control arms guide the wheel through a controlled vertical motion, while ball joints connect them to lightweight aluminum steering knuckles. The coil spring supports the vehicle's weight and absorbs road impacts, and the shock absorber dampens the spring's motion to prevent excessive bouncing. Steering is controlled by a steel tie rod that rotates both front wheels through the steering knuckles.
Outcome
When the vehicle encounters a bump, the tire and suspension work together to absorb the impact while keeping the wheel aligned with the road. During cornering, the double wishbone geometry helps maintain tire contact by generating slight negative camber, improving grip and steering stability. The overall design provides a balance of strength, lightweight construction, ride comfort, and responsive handling. It absolutely deepens my understanding of steering and suspension systems and prepares me for future design.
