Description

Technical Field

[0001] This specification relates to the field of new energy commercial vehicle technology, and in particular to an oil filter system for use in new energy commercial vehicles and the new energy commercial vehicle itself. Background Technology

[0002] Typically, the electric motors or electric drive axles of new energy commercial vehicles are filled with a large amount of lubricating oil to ensure their normal operation. However, because the electric motors or electric drive axles may generate impurities such as metal shavings during operation, the lubricating oil usually needs to be filtered. Furthermore, because the electric motors or electric drive axles operate at high temperatures, the lubricating oil often absorbs a large amount of heat, resulting in a high lubricating oil temperature that cannot reach the optimal lubrication temperature.

[0003] In the prior art, a filter structure is usually installed in the oil pan, and a cooling structure is installed on top of the motor or electric drive bridge.

[0004] However, the lifespan of lubricating oil is usually longer than that of the filter structure. When replacing the filter structure located in the oil pan, a large amount of lubricating oil is often lost. Utility Model Content
