The common electric drive shell of the driving motor 11 and the speed reducer 12 is provided with a filter screen between an oil storage cavity 16 and the electronic oil pump 15, the oil storage cavity 16 is arranged at the front end of the driving motor 11 and at the bottom of the speed reducer 12, the heat exchanger 14 is arranged at the top of the front end of the driving motor 11, and the heat exchanger 14 is a water-oil heat exchanger.
The electronic oil pump 15 adopts a gear pump structure, and sucks and pressurizes and sprays cooling oil in the oil storage cavity 16 into the interior of the all-in-one electric drive assembly 1. The cooling oil directly enters the heat exchanger 14 for cooling along the inside of the shell, and is divided into five branches after being cooled by the heat exchanger 14.
The first branch cools the front end winding and the rear end winding of the stator of the driving motor 11. The first branch takes the output end of the heat exchanger 14 as a starting point, extends the top of the driving motor 11 to reach the middle position of the stator winding of the driving motor 11, then wraps the outside of the stator winding and shunts the front end and the rear end of the stator winding of the driving motor 11 to reach the two ends of the stator of the driving motor 11.

The I-stage hollow shaft of the speed reducer is connected with the hollow shaft of the rotor of the driving motor 11 through a spline, and cooling oil cools the speed reducer when flowing through the spline.
The I-grade hollow shaft of the speed reducer and the hollow shaft of the rotor of the driving motor 11 are communicated. A specific oil path is arranged between the matching clearance of the rotor shaft center and the rotor of the driving motor 11, when cooling oil flows through the center part of the rotor shaft, one part of the cooling oil enters the specific oil path to cool the rotor, particularly the magnetic steel, and the other part of the cooling oil reaches the rear end bearing.

The third branch and the second branch share the inner oil duct of the shell. The outer ring of the bearing is grooved, and cooling oil flows through the high-speed bearing.
Wherein, the fourth branch road cools off I level shaft gear of reduction gear. And the fourth branch takes the output end of the heat exchanger 14 as a starting point, and extends the shell of the all-in-one electric drive assembly 1 to reach the position above the I-stage shaft gear of the speed reducer for spray cooling.
