ADJUSTABLE HYDRAULIC DRIVE FOR MOBILE MACHINE Russian patent published in 2001 - IPC

Abstract RU 2168075 C2

FIELD: drives for mobile machines. SUBSTANCE: drive has working fluid cooling loop including heat exchanger with liquid heat-transfer agent and air cooling agent; cooling loop is provided with hydraulic motor whose shaft holds impeller for forming air flow directed to heat exchanger during rotation of hydraulic motor. Return line is provided with adjustable throttle valve for control of rotational speed of hydraulic motor, thus changing flow rate of air and consequently intensity of heat exchange. EFFECT: simplified construction. 2 cl, 1 dwg
