FIELD: transport mechanical engineering.
SUBSTANCE: method comprises supplying the fluid from tank (14) to hydraulic motors (3) and hydraulic pumps through pipelines (5) and discharging the fluid to tank (14) through drain pipelines (6) through the fluid cooler when a vehicle moves forward. The electromechanical valving members in drain (6) pipeline (6) and pipelines that connect the supplying pipelines with tank (14) and fluid-pressure accumulator (2) are closed. The electromechanical valving members in supplying pipeline (5) and pipelines that connect the tank with the drain pipelines are open. When braking, the fluid is fed through pipelines from tank (14) via fluid cooler to the fluid-pressure accumulator (20) by means of hydraulic pumps (3). The electromechanical valving members in supplying and discharging pipelines are closed, and valving members in pipelines that connect the fluid-pressure accumulator with the supplying pipelines and tank with drain pipelines are open. When vehicle moves back, the fluid is supplied through drain pipelines (6) and is discharged through supplying pipelines (5). The hydraulic drive has hydraulic pump (1) connected to hydraulic motors (3) through supplying (5) and discharging (6) pipelines.
EFFECT: reduced fuel consumption, prolonged service life, and reduced harmful emission.
