FIELD: transport mechanical engineering.
SUBSTANCE: hydraulic vehicle comprises at lest one hydraulic pump (10) which is actuated by engine, one hydraulic motor for actuating wheel (31), hydraulic circuit (50) for connecting hydraulic pump (10) with hydraulic motor (30), and valve (60) for control of flow. The input shaft of hydraulic pump (10) is directly connected with the crankshaft of the engine. Valve (60) returns oil, which is supplied from hydraulic pump (10) to valve (60), to hydraulic pump (10) in the first position. In the second position, valve (60) supplies oil, which is supplied from hydraulic pump (10) to the valve, to hydraulic motor (30). In the third position, valve (60) supplies oil, which is supplied from hydraulic motor (10) to the valve, to the drain branch pipe of hydraulic motor (3).
EFFECT: simplified design and reduced weight.
