The analysis of work of joints of tractors of models DT-YT allows to make the conclusion about presence of breakages because of low constructive strength and not correct definition of parameters of details. Probes of breakages of joints shows that today at designing of joints there is no system of the account of a mode of behavior and joint life cycle. Designing of threaded connections of automobile and tractor technics should be carried out taking into account modes and duration of operation of the car on these modes. Designing of threaded connections is carried out taking into account operation and life cycle modes. It is offered to carry out calculation taking into account accumulation of fatigue damages to a current of set time of operation. For definition of parameters of fatigue strength the technique of the accelerated tests is offered. The technique allows to define parameters of fatigue strength which it is necessary to use in calculations threaded connections. In work probes of a tension of joint of a driving wheel of a Caterpillar, are resulted by a method of the is finitely-element analysis. For probes settlement models are offered and tested. Settlement models allow to simplify construction of geometrical model for use in computer programs and calculations. Using the described technique of designing it is developed construction a retainer screw with a special thread.
