Abstract: The growth of the share of mechanization in the total volume of field work in mountainous and foothill areas or on hilly terrain with areas with significant irregularities and slopes is constrained by insufficient longitudinal and lateral stability of serial tractors.To solve this problem, “CTCAE”RLO has begun work on the development of a tractor with a variable track and base.During field and transport work on areas with significant irregularities and slopes where stability is required, the base of this tractor is set to the greatest.At the same time, for processing relatively flat and small areas where a minimum turning radius is required, on the contrary, its base is set to the smallest.The transfer of the tractor from one base to another is carried out by the mechanism of changing the tractor base.Reliability of work, which largely depends on the parameters of its most critical units and parts that are correctly selected when constructing.The conducted studies have shown that the proposed method for checking the reliability of the hydraulic cylinder axis is also acceptable for checking the reliability of the remaining axles of the mechanism for changing the base of the tractor.In the course of the study, it was found that the parameters incorporated in the design of the axis of the hydraulic cylinder withstand the load applied during the operation of the mechanism for changing the base of the tractor and provides the condition of strength in the dangerous section, that is, (>[(]Т, therefore, the mechanism is operational.
Key words: tractor, front beam, bar, spar, mechanism, base, track, parts, hinge, hydraulic cylinder, load, slope, stability, controllability.
