Oil cooling system and car

Abstract

The invention provides an oil cooling system and a car, and relates to the technical field of cars. The oil cooling system comprises a gearbox, an oil cooler and a thermostat, wherein the thermostat comprises a housing, a first oil inlet tube, a first oil outlet tube, a second oil inlet tube and a second oil outlet tube; one end of the first oil inlet tube and one end of the first oil outlet tubecommunicate with the inner cavity of the housing; the other end of the first oil inlet tube and the other end of the first oil outlet tube communicate with the gearbox; one end of the second oil inlettube and one end of the second oil outlet tube communicate with the inner cavity; the other end of the second oil inlet tube and the other end of the second oil outlet tube communicate with the gearbox; a moveable assembly is arranged in the inner cavity; when the oil temperature is lower than a preset value, the moving assembly moves for disconnecting the inner cavity from the second oil inlet tube; and when the oil temperature is higher than or equal to the preset value, the moving assembly moves for enabling the inner cavity to communicate with the second oil inlet tube. The oil cooling system can keep the oil temperature at the optimal using temperature for a long time, so that oil consumption of an engine can be reduced; and moreover, the inner part of the gearbox is reduced, so thatthe service life of the gearbox is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an oil cooling system and an automobile. Background technique [0002] Modern engines require higher and higher power. In order to obtain higher power for the engine, people have adopted many schemes, but these schemes will inevitably increase the operating temperature of the engine. If the engine is too hot, it means the loss of power, which will reduce the power and economy. At the same time, the high temperature of the cylinder head will also affect the service life of the engine. Therefore, people adopt various methods to cool the engine, such as air-cooled oil-cooled systems and water-cooled oil-cooled systems commonly used at present. [0003] At present, most oil cooling systems are air-cooled oil-cooled systems. During use, the air-cooled oil-cooled system relies on the head-on wind flowing through the air-cooled oil cooler when the car is driving. Because the temper...

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of oil cooling system and automobile, to improve the air-cooled oil cooler in the prior art because the impact of the ambient temperature is relatively large and the specific heat of the air is small, which easily leads to increased engine oil consumption and gearbox service life shorter technical questions
