Elementar question about steering

[Vincent Mazzo]

Hello guys.

My question is: what is the purpose of camber and slip angle? It's only to create an align torque on the wheel?

Thx all

Slip angle should be the angle between your tire's rolling direction and your path of travel. Large factor in cornering power involving numerous factors.

Camber is for establishing a quality of handling of a vehicle.

You should be able to get a good explanation of both of these in Ranger Mike's thread in Race Car Suspensions Class.

There is no «purpose» for the slip angle. It is an observed reaction when a lateral force is applied to the tire.

As for camber, it creates a lateral force on the tire (just like steering angle or toe). So if a tire has camber, it is like the tire is already steered, hence it can react quicker, it is more responsive. Also, as the wheel goes up, we try to have camber gain because - usually - the greater the roll angle, the greater the lateral acceleration, thus the greater the lateral force needed. By having increased camber with roll angle, the car has a tendency to «correct» itself, making it a more stable vehicle.
