DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. Of course, the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Reference Figure 1 and Figure 2 A detachable tractor navigation motor device includes a protective shell 1, a transmission wheel 2 is rotatably provided on the protective shell 1, the transmission wheel 2 is sleeved on the steering column of the vehicle body, a transmission mechanism 3 for driving the transmission wheel 2 to rotate is provided in the protective shell 1, a connecting flange 4 connected to the vehicle body is fixed on the protective shell 1, a connecting hole 5 for the steering column of the vehicle body to pass through is opened on the protective shell 1, and the connecting hole 5 passes through the transmission wheel 2 and the connecting flange 4.

[0025] During installation, the staff inserts the steering column of the vehicle body into the connection hole 5 of the protective shell 1, so that the transmission wheel 2 is sleeved on the steering column, and the connecting flange 4 is fixedly connected to the steering column of the vehicle body. When removing, only the reverse operation is required. The device has a high degree of integration, simplifies the steps of installation and debugging, and is more convenient for maintenance and replacement.

[0026] In this embodiment, the protective housing 1 includes a main housing 11 and a sealing plate 12. The transmission wheel 2 and the transmission mechanism 3 are both located inside the main housing 11. The sealing plate 12 is detachably mounted on the main housing 11 through fasteners. Specifically, the fasteners are bolts. In this way, the transmission wheel 2 and the transmission mechanism 3 inside the protective housing 1 can be maintained, and when in use, the protective housing 1 protects the transmission wheel 2 and the transmission mechanism 3.

[0027] The transmission mechanism 3 includes a driving motor 31, a driving gear 32, a driven wheel assembly 33 and a transmission belt 34. The driving motor 31 can be detachably installed in the main housing 11 by bolts. The driving gear 32 is coaxially fixed on the output shaft of the driving motor 31. The driven wheel assembly 33 includes a first driven gear 331 and a second driven gear 332. The first driven gear 331 and the second driven gear 332 are axially fixedly connected. The first driven gear 331 and the second driven gear 332 are coaxially rotatably installed in the main housing 11. The transmission belt 34 is respectively meshed with the second driven gear 332 and the transmission wheel 2. Among them, the diameter of the first driven gear 331 is greater than the diameter of the second driven gear 332, the diameter of the driving gear 32 is smaller than the diameter of the first driven gear 331, and the diameter of the second driven gear 332 is smaller than the diameter of the transmission wheel 2. In this way, multi-stage reduction transmission can be achieved, the transmission mechanism 3 has fewer components, the space occupation is reduced, the energy loss in the transmission process is reduced, and the energy utilization rate is high.

[0028] It should be added that a steering wheel is coaxially fixed to the steering column by bolts to facilitate manual control of the direction. When the navigation motor is working, the transmission mechanism 3 drives the transmission wheel 2 to rotate. Since the transmission wheel 2 always remains coaxial with the steering column, the transmission mechanism 3 drives the protective housing 1 to rotate around the transmission wheel 2. When the protective housing 1 rotates, it drives the steering wheel and the steering column to rotate synchronously, thereby realizing the steering of the vehicle body.

[0029] Reference Figure 1 and Figure 3 The main housing 11 is provided with a first bracket 6 and a second bracket 7. The first bracket 6 is provided with a first support hole 61 and a second support hole 62. The output shaft of the drive motor 31 is passed through the first support hole 61. The first support hole 61 supports the output shaft of the drive motor 31. The second bracket 7 is provided with a third support hole 71. The third support hole 71 is coaxial with the second support hole 62. The two end shafts of the driven wheel assembly 33 are respectively located in the second support hole 62 and the third support hole 71. The second support hole 62 and the third support hole 71 support the two end shafts of the driven wheel assembly 33. This method can improve the overall stability of the transmission mechanism 3 and ensure the transmission effect.
