Abstract

The invention provides a gearbox cooling system and a cooling method thereof and a vehicle, and relates to the technical field of vehicle equipment. The gearbox cooling system comprises a gearbox body, a first thermostat, a second thermostat, an air-cooled oil cooler and a water-cooled oil cooler. Engine oil flowing of the gearbox body and the air-cooled oil cooler is controlled through the firstthermostat. When a gearbox is started and warmed up, engine oil in the gearbox body is not cooled, and the warming-up speed of engine coolant is increased. In addition, when the air-cooled oil coolercannot meet the cooling requirements, engine oil flowing of a gearbox oil inlet pipe and the water-cooled oil cooler is controlled through the second thermostat, so that the cooling efficiency of theengine oil is improved through the added water-cooled oil cooler. The technical problems that cooling efficiency is low, and vehicles are high in oil consumption when started again after not working for a long time in the prior art are alleviated. The temperature of the coolant is controlled more precisely, and an engine and the gearbox can work in a proper temperature range under various workingconditions.

Description

technical field [0001] The invention relates to the technical field of automobile equipment, in particular to a gearbox cooling system, a cooling method thereof and an automobile. Background technique [0002] With the rapid development of the automobile industry and the improvement of people's living standards, automobiles have become an indispensable means of transportation in people's daily life. The cooling and lubrication of the oil in the gearbox in automobiles is one of the key technologies in the design and development of gearboxes. It is directly related to the long-term safe use and reliability of the transmission; the transmission cooling system is mainly for automatic transmissions. A large number of operating mechanisms of automatic transmissions are driven by hydraulic systems, and their heat generation is much greater than that of manual transmissions. To ensure the working reliability of the gearbox, the automatic gearbox is equipped with a gearbox oil cooler...
