The article presents results of the reliability study of controlled groups of vehicles possessed by two road transport enterprises working in the international transport sector (truck tractors – VOLVO FH 1242Т – 50 unit and MERCEDES-BENZ 1844 ACTROS LS -100 units, semi-trailers SCHMITZ, KRONE and KÖGEL – 50 units from each of the semi-trailers company). Possibilities for reliability increasing and reduction of the maintenance and repair cost are defined. The results of the reliability evaluation of vehicles during three years of operation with a different annual run (from brand new up to 440·103 km, including warranty period) are presented. Based on the conducted studies of failures and details malfunctions, units and systems of the vehicles, the average operating time to failure or occurrence of malfunctioning, the probability of failure-free operation, and the time spent on repairs were determined. Asymmetric graphs of working capacity disturbance were obtained, which allowed determining the level of const uction design perfection, the technological accuracy of equipment assembly and the quality of fastening works. The inadequate adaptability to operate on the roads of the CIS was reflected by symmetric distribution laws. The least reliable aggregate and assembly elements were identified.

Intensity and form of wear of tire′s tread depends on the technical state of assemblies of car suspension. The database according to the information of control of the height of the protector picture is forming. On its basis on the developed system of maintenance of tires setting of norms, prognostication and optimization of resource of tires is made, necessary repair influences of tires and assemblies of suspension are appointed.

Интенсивность и форма износа протектора шин зависит от технического состояния функциональных узлов подвески автомобиля. По данным контроля высоты рисунка протектора формируется база данных. На ее основе по разработанной системе обслуживания шин производится нормирование, прогнозирование и оптимизация ресурса шин, назначаются необходимые ремонтные воздействия для шин и узлов подвески.

The dependences of tire wear on the tire life are determined on the basis of the system measurements of residual tread depth in the actual operating conditions; the factors which influence the critical tire wear are analyzed. The prediction technique of the operation life and the tire changing is devised.
