How does lateral load transfer occur?

Lateral load transfer occurs during cornering and is the shift of mass across the wheels due to the centrifugal force and the lateral acceleration. When a car is cornering it creates a force called centrifugal force. This force works against the lateral acceleration which is created by the grip from the tyres known as the tyre cornering forces.

What are the three mechanisms of lateral load transfer?

Lateral Load Transfer from Unsprung Mass: The simplest component of load transfer. If unsprung mass is isolated, it’s possible to find its own CG. When the car corners, lateral acceleration is applied at this CG, generating a centrifugal force which will result in a moment, that can be divided by the axle track to yield a lateral load transfer component.; Load Transfer from Direct Lateral Force (Kinematic Load Transfer Component): It is one of the two components related to the lateral force acting upon the sprung mass. It arises from the force coupling effect that roll centres have, directly linking forces on sprung mass to the unsprung mass.; Load Transfer Due to Roll Angle (Elastic Load Transfer Component): During spring displacements, a force on each spring arises, and these forces generate a moment that tends to resist the rotation of the body. These forces are reacted by the tyres, and that contributes to lateral load transfer. This component is also referred as the elastic weight transfer component.
