Abstract

Vehicle stability, handling and braking properties significantly depends on the friction interaction between a tyre and the road surface. Index of the friction interaction is the coefficient of friction in different coordinates. The friction coefficient is generally calculated as a function of the coefficient of the longitudinal slip of the wheel x  f (sx ) . The lateral force significantly affects the coefficient of friction. In different cases the lateral force can occur either before or after occurrence of the braking moment on the wheel. The purpose of the study is to investigate the effect of different sequence of occurrence of the lateral force and the braking moment on a wheel on the friction properties of the tyre with a solid road surface. The author have developed the methods which allows considering the sequence of occurrence of the lateral force and the moment on the wheel in the calculation of x  sx – diagrams.
