Description

technical field [0001] The invention relates to a manufacturing technology of an electric vehicle, in particular to an intelligent oil temperature control device for a main reducer of an electric vehicle. Background technique [0002] At present, the general-purpose main reducer of electric vehicles generally has a large speed ratio, and adopts cylindrical gear transmission. The rotational speed of the cylindrical gear is very high. The lubricating performance is reduced, affecting the lubrication of the gears, causing disadvantages to the meshing of the gears, and even causing the adhesion of the teeth and burning the gears. Therefore, the intelligent temperature control of oil temperature is the key to the use of the final drive of electric vehicles, and it can also ensure the normal driving of electric vehicles. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intelligent oil temperature control device for ...
