Study on the Matching of Toe-in and Camber of the Double-Front-Axle Steering Automobile

[摘要] Toe-in and camber of the wheel are important driving performance parameters in the four-wheel positioning parameters of automobile. In this paper, the mathematical geometrical models of toe-in and camber of the first and second bridges of the double-front-axle automobile are established, concluded that the relationship of toe-in and camber between the first bridge and the second bridge. At the same time, based on the side slip mechanism of the tire, the reasonable matching formula for toe-in and camber of the double-front-axle are concluded. Finally, according to the dynamic model established in the Adams/Car, the matching values of toe-in and camber are simulated and verified. The experimental results show that the matching value is reasonable and effective, for the matching of toe-in and camber of double-front-axle steering wheel has a certain guiding role.
