Research into a bit of automotive stuff

Nice when someone in the auto industry remembers me, today I am trying to find photos of independent rear suspension assemblies and how the different designs control bump steer.

Bump steer happens when the car is loaded either across the lateral or vertical axis. The affected wheels can move forward or back depending on the loading. This movement makes the wheel move and steer that side of the car independent of steering wheel inputs. Most manufacturers accept some bump steer and even use it to assist turn in. However in a racing situation the drive needs these inputs to be predictable and try to eliminate it.

To check how much a wheel moves race teams have made tools to do the job. Check out this unit on an older Nascar.
