FIELD: transport engineering; crawler vehicles.
SUBSTANCE: proposed vehicle hydraulic drive has adjustable pump 1 and hydraulic motor 2 connected by hydraulic line into closed circuit. Make-up pump 5 is installed on one shaft 6 with adjustable pump 1, being connected to closed circuit through check valves 7 and 8 and provided with drain into housing of adjustable pump 1. Output of make-up pump 5 is connected with input through housing of adjustable pump 1, cooler 9 and filter 11 to form closed circuit connected with working space of hydraulic accumulator 19 whose minimum volume is chosen basing on specific conditions.
EFFECT: reduced overall dimensions and mass of hydraulic drive, increased efficiency.
