The invention discloses a wet drive axle integrated with an automatic lubricating and cooling system, which comprises a torsion transmission unit and a transmission shaft I. The transmission shaft I is provided with a front bearing and a rear bearing, the front bearing is provided with a temperature sensor, and the transmission shaft I is sequentially linked with a differential assembly, a planetary transmission assembly, a hub assembly and a multi-piece wet brake assembly. The multi-disc wet brake assembly is provided with a temperature sensor; a pump speed-increasing gear I is arranged in the middle of the transmission shaft I, the pump speed-increasing gear I is in linkage with a pump speed-increasing gear II, the pump speed-increasing gear II is provided with a transmission shaft II, the transmission shaft II comprises a clutch, the other end of the transmission shaft II is connected with an oil pump in a matched mode, the oil pump is provided with an oil pool, and an oil outlet of the oil pump is connected with an electromagnetic reversing valve in a matched mode. When the temperature sensor measures that related parts of the drive axle brake are overheated, the controller assembly controls the clutch to be closed to drive the oil pump to work, the electromagnetic reversing valve can be adjusted according to needs under the control of the controller assembly, and then the related parts are automatically lubricated and cooled.
