Anti-dive A vehicle which is braking will experience a longitudinal force at its centre of gravity. This force will cause the vehicle to pitch and is mainly reacted by the suspension springs and dampers. ...
Bump steer in a suspension system describes the change in wheel steer angle as the suspension moves through its vertical travel. Learn more with this interactive course and linked simulation exercise.
Steering ratio is a ratio of the degrees of steering wheel angle input and degrees of road wheel toe angle change. Steering ratio is a function of rack ratio (mm of rack travel per ...
Spring ratio/Damper ratio is a ratio between the displacement of the spring/damper and the vertical displacement of the wheel centre. As the spring and dampers on a suspension system are mounted inboard of the ...
This KPI measures the suspension track width between the tyre contact patch centres. The centre of the tyre contact patch is considered the geometric centre of the tyre projected from the wheel centre. For ...
Brake steer is a metric to measure the amount of self steer generated by a suspension system when it is subject to a braking (longitudinal) load at the contact patch. Brake steer is measured ...
Tyre Torque compliance is a measure of the compliance of a suspension system when subject to a tyre self-aligning torque. Tyre torque compliance is measured in Degrees of toe change per Kilo-Newton Metre of ...
Contact patch compliance is a metric to understand the level of lateral deformation in a suspension system when subject to a lateral cornering force at the tyre contact patch. It is measured in millimetres ...
Wheel rate is a measure of the effective stiffness of the suspension system measured at the wheel centre. The wheel rate is the slope of a graph plotting wheel force vs wheel travel. It ...
Contact patch lateral migration is a metric to measure the amount of lateral movement of the tyre contact patch for a vertical movement of the suspension. It is measured in millimetres of lateral movement ...
