Anti Squat Suspension

Rear suspension kinematic characteristic which reduces the amount of pitch under acceleration.

Forces under acceleration.

Where


Faccel = Force due to acceleration [N]
m = Vehicle mass [kg]
a = acceleration [ms-2]

Dimensions as given in figure.

When the centre of gravity of the vehicle is not at exactly the same location as the pitch centre then any longitudinal accleration will result in a pitch rotation of the vehicle.

Under acceleration the vehicle will squat down at the rear end. An Anti Squat Suspension will be designed to limit this effect.
