摘要:
A work vehicle equipped with a main engine, a main engine gearbox and a main engine cooling circuit for circulating an engine coolant, the cooling circuit comprising at least one sub-portion comprising a radiator for heating the driver's cabin of the work vehicle. A heat exchanger is configured for heat exchange between said engine coolant and a lubricant flowing in a circuit into and out of a gearbox other than the engine gearbox. This latter gearbox can be the traction gearbox driven by a hydrostatic motor that is in turn powered by main-engine driven pump. The traction gearbox oil is then cooled by the engine coolant when the temperature difference between the engine coolant and the traction gearbox oil is higher than when the work vehicle is in active operation in the field.
