Among them, the bearing 14 is preferably a rolling bearing. The output end of the motor 6 is connected with the electromagnetic clutch 5, and specifically, the rotor of the motor 6 is connected with the electromagnetic clutch 5 through a flat key. The electromagnetic clutch 5 is connected with the transmission shaft 3, and specifically, the electromagnetic clutch 5 is also connected with the transmission shaft 3 through a flat key. The pinion 4 is fixedly mounted on the drive shaft 3 between two shoulders, in particular, the pinion 4 is mounted on the drive shaft 3 by a flat key.

It is understood that the on and off of the electromagnetic clutch 5 is controlled by the on and off of the current, and when the current of the electromagnetic clutch 5 is controlled to be on, the electromagnetic clutch 5 is closed, and the steering mode of the tractor is switched to the electronic steering mode. At this time, the driver of the motor 6 drives the rotor of the motor 6 to rotate, and the rotor rotates to drive the electromagnetic clutch 5 to rotate, so as to drive the transmission shaft 3 to rotate. Since the small gear 4 is connected with the transmission shaft 3 in a key mode, the small gear 4 can rotate along with the transmission shaft 3, the large gear 10 is meshed with the small gear 4, and the small gear 4 drives the large gear 10 to rotate.
