Abstract:
This paper presents an investigation into the effect of front wheel steer geometry on steer induced load transfer. An inhouse mathematical model has been developed which quantifies and illustrates these effects. The model has also been used to predict how common geometry variables affect the resulting steer induced load transfer.It is shown that the effect of steer on overall load transfer is significant, especially for high roll stiffness vehicles, and that the effect may be used to manipulate vehicle handling balance. The paper also shows that the resulting load transfer can be controlled by utilising an upright mounted pushrod design and how such a configuration may also be used to control front ride height with steer.The relationships between common design variables and the resulting steer effect have been determined.
