Description
Technical Field
The present invention relates to an automatic transmission built-in cooling system.
Background
Wet double clutches are a very important component in transmission drive trains that rely on friction between friction plates and dual steel plates to effect power transfer. When the friction plates and the dual steel plates of the wet double clutch are combined and gradually move synchronously, a large amount of friction heat is generated due to the fact that the rotation speeds of the two plates are different and mutual sliding friction occurs between the plates. If the heat generated by friction is not timely dissipated, the failure of the friction plate can be caused, and the whole service performance of the double clutch is directly affected. At present, there are various cooling modes of a wet-type double clutch automatic transmission, in which a water tank integrated cooling mode, i.e., a cooling water tank is arranged on a clutch housing and is formed by die casting in one piece, and the wet-type double clutch automatic transmission is widely used due to its simple structure, low cost and high cooling efficiency. However, due to casting defects of the die-cast aluminum shell, such as air holes, shrinkage porosity, cracks and cold insulation, cooling liquid can gradually infiltrate into the interior of the transmission through the inner wall of the cooling water tank of the shell when flowing through the cooling water tank of the shell, so that the water content in the transmission oil is continuously increased. The friction plates and the steel plates of the wet double clutch are immersed in gearbox oil, and abnormal abrasion of the steel plates of the wet double clutch can be caused by the fact that the water content in the gearbox oil exceeds the standard, so that the power transmission function of the wet double clutch transmission is invalid, and the problems of running and noise of the whole vehicle in the gear shifting or uniform running process are presented. Therefore, improvements in this cooling scheme are needed.
