The integrated axle of automobile mainly comprises a speed reducer assembly and a differential mechanism assembly, and adopts gear engagement to realize speed reduction and transmission, and lubrication is needed for reducing friction loss, reducing power consumption, increasing transmission efficiency, improving working condition of gears and maintaining running engagement and expected service life of gears. The passive lubrication technology applied to the axle in the prior art has low maintenance cost, does not need to install an additional lubrication system, and is easy to replace lubricating oil, but the consumption speed of the lubricating oil in actual use is high, the quantity and quality of the lubricating oil cannot be effectively controlled, so that friction and abrasion are increased, and the reliability and service life of the automobile are greatly reduced.
