Abstract

The invention provides a cooling liquid path structure of transmission oil, an oil cooling integration module and an installation structure of the oil cooling integration module. The cooling liquid path structure comprises cooling liquid paths and a control valve device arranged on the cooling liquid paths, the cooling liquid paths comprise the first cooling liquid path and the second cooling liquid path, a water inlet of the first cooling liquid path is used for being communicated with a water outlet of an engine cylinder water jacket, a water inlet of the second cooling liquid path is used for being communicated with a cooling water tank, a water outlet of the first cooling liquid path and a water outlet of the second cooling liquid path are both used for being connected with a water inlet of a transmission oil cooler, the control valve device can be switched into three work states by inducing the water temperature of the engine cylinder water jacket and the temperature of the transmission oil so as to guarantee that the temperature of the transmission oil can change according to different working conditions of a vehicle and can always be in the optimal range of the corresponding working conditions, and accordingly reliability of the whole vehicle is improved.

Description

technical field

[0001] The invention relates to the technical field of vehicle oil cooling, in particular to a transmission oil cooling liquid circuit structure, an oil cooling integrated module including the cooling liquid circuit structure and used for cooling engine oil and transmission oil, and a transmission oil cooling circuit structure. The installation structure of the oil cooling integrated module. Background technique

[0002] Whether the cooling and lubrication performance of the vehicle's engine and transmission is good directly affects the fuel economy, emission performance, reliability and service life of the engine.

[0003] Considering the overheating problem of transmission oil, the existing design usually takes water from the engine cooling circulation water circuit to cool the transmission oil, and after cooling, the coolant returns to the engine water inlet. However, the existing design only considers the working conditions of the engine when it is runni...
