[0002] Normally, a large amount of lubricating oil is filled inside the electric motor or electric drive axle of a new energy commercial vehicle to ensure the normal operation of the electric motor or electric drive axle. However, since the electric motor or electric drive axle may generate impurities such as metal debris during operation, the lubricating oil usually needs to be filtered. In addition, since the temperature of the electric motor or electric drive axle is high during operation, the lubricating oil tends to absorb a large amount of heat, resulting in a high temperature of the lubricating oil, which cannot be at the optimal lubrication temperature.

[0003] In the prior art, a filtering structure is usually provided on the oil pan, and a cooling structure is provided on the top of the electric motor or the electric drive axle.

[0004] However, the service life of the lubricating oil is usually longer than the service life of the filtering structure. When the filtering structure arranged on the oil pan is replaced, a large amount of lubricating oil is often lost. Summary of the invention

[0059] Further preferably, the size of the lubricating oil sealing hole is slightly smaller than the size of the top surface of the oil filter 2, so that the edge portion of the top surface of the oil filter 2 can contact the bottom surface of the heat exchange mounting assembly 3, thereby making it impossible for the oil filter 2 to pass through the lubricating oil sealing hole or be accommodated by the lubricating oil sealing hole.

[0060] Preferably, a limiting member and / or a supporting member is disposed in the first space 51 of the integrated mounting seat 5 .
