In recent years, new energy vehicles have developed rapidly. The new energy vehicle refers to a vehicle that uses unconventional vehicle fuel as a power source (or uses conventional vehicle fuel, adopts a new vehicle power device), and combines advanced technologies in vehicle power control and driving to form a vehicle with advanced technical principles and new technologies and structures.

[0003] In the transmission system of the new energy vehicle, the reduction gear is usually used.

When the electromagnetic plate moves, the guide rod 712 can guide the second connecting block 714, thereby guiding the movement of the electromagnetic plate.

[0045] With reference to Figure 4 and Figure 5 , the coaxial connecting mechanism 8 comprises a shaft coupling 81 and a detection assembly 82. The detection assembly 82 comprises a laser emitter 821, a laser receiver 822 and two mounting structures 823. Each mounting structure 823 comprises a mounting belt 8231, a mounting frame 8232 and two mounting rods 8233.

Then, the electromagnetic suction plate is powered on to fix and adsorb the speed reducer 2 on the electromagnetic suction plate. The position of the speed reducer 2 in the vertical direction is adjusted by the hydraulic cylinder 721, so that the speed reducer 2 is coaxial with the first sensor 5 and the second sensor 14.

[0049] The input shaft of the speed reducer 2 and the rotating shaft of the first sensor 5 and the output shaft of the speed reducer 2 and the rotating shaft of the second sensor 14 are fixedly connected through the shaft coupling 81.
