The rear end of the drive motor 1 is equipped with a cooling fan (not shown in the figure), which will take away the heat around the drive motor 1 when working, realize the heat dissipation of the drive motor 1, and can dissipate the heat generated by the traction motor water cooling device, with good heat dissipation effect.

[0026] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, mounting seats 31 are arranged on both sides of the mounting shell 3, and shock-absorbing pads 7 are arranged on the two mounting seats 31. The mounting seats 31 are used to connect the entire mounting shell 3 to the water cooling device.

[0027] In one embodiment, see Figure 1 , Figure 3 and Figure 4As shown, a guide plate 32 is arranged inside the mounting shell 3 to prevent the right-angle flow channel inside the cavity of the mounting shell 3 from causing impact loss to the airflow. The guide plate 32 is arranged above the cavity of the mounting shell 3. The guide plate 32 is an integrated spiral structure, which makes the airflow flow more smoothly in the mounting shell 3.
