Optimization of Suspension Initial Alignment Parameters Based on Reducing Tyre Wear

The purpose of this study is to improve auto suspension parameters so as to reduce tyre wear through the analysis of the relationship between suspension and tyre wear, so as to improve the running performance and economical character of vehicle. The spatial movement of double link independent suspension and tyre movement with different front wheel alignment parameters are analysized by means of kinematics and spatial analytic geometry. Evaluation of the degree of the tyre wear is provided so that to build the mathematic model relating the movement of double links independent suspension, the front wheel alignment parameters and tyre wear together. Furthermore the influence of initial alignment parameters and state parameters of double link independent suspension on tyre is analysed and an optimal method is provided to adjust initial alignment parameters to reduce tyre wear. Finally, an actual optimal analysis is made for a light duty truck as an example.
