Double Wishbone Suspension - How does it work?

To first understand DWS, it’s important to understand camber.

...

These are cool because they allow each suspension to act independently - if there is a bump on the road that affected only the front right wheel, it’s suspension system is the only one that would react. (Race Car Design by Derek Seward - 3.1: Introduction to Racing Car Suspensions)

The Bell Crank

...

Push Rod, Bell Crank, Shock

A push rod “pushes” so that the bell crank can transfer motion to the shock. (pull rods also exist)

...

Important note: External vs Internal suspension system hardpoints are the EXACT same.

Objectives:

• Understand Bell Cranks

• Hex vs Rect multilevel frame arc

• Improve current front frame design

You don’t want a large mounting distance, one problem w/this is huge upright.

One problem w/Daybreak - pedal box

• Ergo unhappy (small space)

• Suspension unhappy (ctrl arms far apart)

• Frame unhappy (prob bad load handling)

Overall, loss-loss-loss situation

Hexagon frame is better cuz smaller top control arm (facilitates negative camber for cornering)

Note: Recommendation for dY b/w ctrl arms is 9 in, sus currently tryna do 8 in.

Below are diagrams, ignore everything except for the bottom left hexagon. It’s a diagram of how suspension would look like on the front frame.
