4. the utility model mode occurs using axle stretch end, arrangement is conducive to keep apart high-low pressure, avoids signal dry
It disturbs, is conducive to the accurate control of signal；The space of motor Yu the oblique side of retarder is utilized to the greatest extent, it is empty to reduce height
Between, improve the utilization rate in space.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and embodiments:
Fig. 1 is the overall schematic of the three-in-one shell structure of the utility model；
Fig. 2 is the schematic diagram of the utility model motor water channel and controller water channel；
Fig. 3 is the utility model controller and motor wiring schematic diagram.
Specific embodiment
As shown in Figure 1, the three-in-one shell structure of the revealed controller of the utility model, retarder, motor, including one
Controller housing 1, reducer shell 2 and the electric machine casing 3 of body casting and forming.The reducer shell 2 is retarder half-shell, position
In the front end of electric machine casing 3, while as electric motor end cap 4.The controller housing 1 is located at retarder half-shell and electric machine casing
Side wall top.Three-in-one shell structure is realized using low pressure casting or lost foam casting process.
As shown in 2, the motor water channel 31 of radial direction M type, since motor temperature is higher, electricity are equipped in the electric machine casing 3
