The motor 1 is started to drive the transmission shaft 14 to rotate, so that the transmission shaft 14 drives the wheel hub 15 to rotate, so that the AGV trolley can be driven;

[0028] The mounting plate 2 is fixedly mounted on the outside of the motor 1, and the outside of the mounting plate 2 is connected to a suspension fixing plate 3, a fixing block 20 is fixedly mounted on the inside of the suspension fixing plate 3, and a limiting rod 21 is connected to the middle side of the fixing block 20, a first spring 4 is arranged on the upper end of the suspension fixing plate 3, and a moving rod 5 is connected through the middle of the first spring 4, a connecting tube 8 is connected to the outside of the first spring 4, and a replacement structure is connected to the upper side of the connecting tube 8, a connecting block 9 is fixedly mounted on the upper side of the moving rod 5, and a mounting block 6 is fixedly connected to the lower side of the moving rod 5, and a fixing rod 7 is connected to the outside of the mounting block 6, and the limiting rod 21 is rotated so that the limiting rod 21 is in the suspension The middle inner side of the hanging fixing plate 3 is connected, so that the limiting rod 21 is connected to the middle side of the fixing block 20, and then the limiting rod 21 is separated from the middle outer side of the mounting plate 2, and then the hanging fixing plate 3 is pulled outward, so that the hanging fixing plate 3 drives the fixing block 20 to separate from the middle outer side of the mounting plate 2, which is convenient for disassembling the hanging fixing plate 3, rotating the replacement structure, so that the replacement structure is separated from the inner side of the connecting block 9, and then pulling the connecting tube 8 upward, so that the connecting tube 8 is separated from the outer side of the connecting block 9, so that the connecting tube 8 is separated from the outer side of the moving rod 5, which is convenient for replacing the first spring 4 inside the connecting tube 8;

[0029] The connecting tube 16 is fixedly mounted on the outer side of the wheel hub 15, and a third spring 17 is arranged on the outer side of the wheel hub 15. A connecting rod 18 is connected through the middle side of the third spring 17, and a wheel 19 is fixedly mounted on the outer side of the connecting rod 18. When the AGV trolley passes over a bump or obstacle during driving, the third spring 17 on the outer side of the wheel hub 15 is elastically deformed and compressed, and the wheel 19 moves upward, so that the wheel 19 drives the connecting rod 18 to slide on the inner side of the connecting tube 16, but the wheel hub 15 and the transmission shaft 14 do not move or move very little due to elastic potential energy. When the squeezing force disappears after passing over the bump, the third spring 17 returns to its original shape, and the trolley continues to drive normally. If the displacement of the wheel 19 is too large, the third spring 17 on the outside of the wheel hub 15 will be elastically deformed to the limit and will be unable to buffer the vibration. At this time, the connecting tube 8 and the moving rod 5 arranged on both sides of the motor 1 achieve the vibration reduction effect through the elastic deformation and elastic potential energy of the first spring 4, maintain the stability of the wheel hub 15 and the transmission shaft 14, ensure the transportation stability of the AGV trolley, and facilitate improving the vibration reduction and stability effect of the main driving wheel of the AGV trolley.

When the AGV trolley presses over a bump or an obstacle during driving, the third spring 17 on the outside of the wheel hub 15 is elastically deformed and compressed, and the wheel 19 moves upward, so that the wheel 19 drives the connecting rod 18 to slide on the inside of the connecting tube 16, but the wheel hub 15 and the transmission shaft 14 will not be displaced or will be displaced less due to elastic potential energy. When the squeezing force disappears after crossing the bump, the third spring 17 returns to its original shape, and the trolley continues to travel normally. If the displacement of the wheel 19 is too large, the third spring 17 on the outside of the wheel hub 15 is elastically deformed to the limit and cannot play a role in buffering vibration. At this time, the connecting tube 8 and the moving rod 5 arranged on both sides of the motor 1 achieve a vibration reduction effect through the elastic deformation and elastic potential energy of the first spring 4, maintain the stability of the wheel hub 15 and the transmission shaft 14, ensure the transportation stability of the AGV trolley, and facilitate improving the vibration reduction and stability effect of the main driving wheel of the AGV trolley;

[0032] Specific as Figure 1 and Figure 2In the process, the mounting rod 13 is rotated so that the mounting rod 13 is threadedly connected to the outer side of the middle part of the connecting block 10, thereby separating the mounting rod 13 from the outer side of the connecting block 9. The connecting rod 12 is connected to the connecting block 10 in a sliding manner, and the vertical cross-section of the connecting rod 12 is a "T"-shaped structure. The connecting rod 12 is then pulled inward so that the connecting rod 12 drives the second spring 11 to extend, thereby separating the connecting rod 12 from the inner side of the connecting block 9.
