Abstract
Steered wheels suspension geometry of truck is of great importance for exploitational characteristics, since it affects vehicles handling (stability of steered wheels), loading of steering system elements and suspension and tire wear. The mentioned phenomena are related to drivers fatigue, therefore a considerable attention must be devoted to the optimal choice of those parameters, both in the phase of design and during the truck service life.
In this paper an attempt was made to develop an analytical method for determination of orientational values of the steered wheels suspension geometry parameters in the truck design phases. The method is based on the front wheels shimmy minimization, and aligning torque maximization, for the condition of circular motion with constant speed.
