Palaguta V. Improvement of the system of technical maintenance of tractor hydraulic drive.

Dissertation deals with the technology development of technical maintenance of hydraulic drive of steering gear of agricultural tractor/ Mathematical models of hydraulic drive functioning of tractor steering gear in the case of varying of technical status of hydraulic units are proved. The Dynamic elevating of working liquor pressure is the most informative parameter of hydraulic drive of steering gear; it is proved on the base of above-mentioned Built-in in indicators of technical hydraulic status of drive of steering gear are devised; the technologies of technical maintenance are applied. Employed system of technical status maintenance of hydraulic drive of steering gear of T-type tractors ensure 0,25 hours reduction of labour per cycle of technical maintenance as well as economizing of 1,7 kg of working liquor
