[0016] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] Reference Figure 1-Figure 4As shown, a steering wheel with a shock absorbing device comprises a hub motor 1, a support frame 1 2, a support frame 2 3, a bearing 10, a support rod 1 11, a support rod 2 12, a shock absorber 4, an absolute value encoder 5, a reduction motor 6, a motor drive gear 7, an encoder gear 8 and a steering wheel main gear 9. One end of the support frame 2 3 is connected to two support frames 1 2, and the other end of the support frame 2 3 is connected to two shock absorbers 4 through two support rods 2 12. The hub motor 1 is installed in the middle of the support frame 1 2, and the rear end of the support frame 1 2 is connected to the two shock absorbers 4 through a support rod 1 11. A reduction motor 6 and an absolute value encoder 5 are installed on both sides of the support frame 2 3, respectively. A motor drive gear 7 is installed on the reduction motor 6, and an encoder gear 8 is installed on the absolute value encoder 5. A bearing 10 is installed on the top of the support frame, and the outer ring of the bearing 10 is connected to the steering wheel main gear 9.

[0018] Specifically, the hub motor provides forward power for the steering wheel, and the reduction motor drives the middle hub motor to rotate through the gear connection to achieve overall steering. The absolute encoder monitors the angle of the hub motor in real time, which can not only accurately control the rotation angle, but also turn the steering wheel to the appropriate angle during the initialization process to facilitate subsequent rotation control.

[0019] Specifically, two shock absorbers are installed behind the steering wheel, which can effectively absorb impact force during the steering wheel driving process, adapt to various terrains, and ensure the smooth operation and work efficiency of the AGV.

[0020] Specifically, since the steering wheel chassis has no fixed structure, the user can select a suitable number of steering wheels according to his or her own needs, thereby improving the versatility of the steering wheel.

[0021] Specifically, since there is no angle restriction on the rotation direction of the steering wheel, it can be flexibly rotated 360 degrees in any direction in a small space.
