Exploring on optimum matching of vehicle toe-in and camber

The design of front wheel alignment parameters is still one of the problems of vehicle product developing. According to the research achievement of matching relations of vehicle toe-in and camber, a new calculation method on vehicle front wheel toe-in and camber was developed, considering the mechanism and the properties of tires and construct parameters of vehicle. The new formula was proved by the side slip tests of a YZK1026B model picking-up truck. A series of the results on front wheel side slip were tested by changing the sample truck front wheel toe-in. That can improve the match of front wheel toe-in and camber in the the properties of vehicle front wheel alignment parameters. In this paper a new concept on cornering force of toe-in was put forward.
