FIELD: mechanical engineering.
SUBSTANCE: invention can be used in hydraulic systems of tractors and other self-propelled and road-building vehicles. Proposed hydraulic drive has pump unit with drive motor 4. It consists of three nonadjustable pumps 1, 2, 3 with proportional three-position hydraulic distributor 8. Four-position hydraulic distributor 15 is connected through pressure hydraulic line 14 with pump unit, and through hydraulic lines 16, 17, with hydraulic motors 18 and 19. Hydraulic cylinder 13 is installed in pressure hydraulic line 14 through three-position hydraulic distributor 10. Controllable flow regulators 20 and 21 are placed in section between four position hydraulic distributor 15 and hydraulic motors 18 and 19. Hydraulic accumulator 28 is placed in pressure hydraulic line 14 through two-position hydraulic distributor 26.
EFFECT: reduced energy consumption in operation of hydraulic system, elimination of skidding of vehicle and spinning of wheels at straight-ahead running.
