[0026] like Figures 1-3 As shown in the figure, this utility model embodiment provides an AGV trolley steering wheel.

[0027] An AGV (Automated Guided Vehicle) steering wheel includes a housing 1 and a wheel 2. A steering gear 3 is fitted around the upper outer periphery of the housing 1. A first cavity 4 is located at the center of the top of the housing 1. A second cavity 5 is located on the outer side of the top of the housing 1. A connecting part 6 is located at the bottom of the housing 1 near the second cavity 5. A third cavity 7 is located inside the connecting part 6. The first cavity 4, the second cavity 5, and the third cavity 7 are sequentially connected. An input shaft 8 is rotatably mounted inside the first cavity 4, and a first gear 9 is mounted on the input shaft 8. A first rotating shaft 10 is rotatably mounted inside the second cavity 5, and a second gear 11 is mounted on the first rotating shaft 10. A reduction gear set 12 is located inside the third cavity 7. The first rotating shaft 10 is connected to the input end of the reduction gear set 12, and the output end of the reduction gear set 12 is connected to the wheel 2. The wheel 2 is located below the housing 1.

[0028] This invention integrates the input shaft 8, gear set, and reduction gear set 12 within the housing 1 by setting multiple interconnected cavities inside the housing 1. This avoids the bulky size associated with traditional external motors and linkage mechanisms, effectively reducing the overall structural size and improving space utilization. It is suitable for AGV chassis designs with strict space constraints. The direct gear meshing transmission method reduces energy loss during transmission, improves power transmission efficiency, and enhances the energy efficiency ratio of AGV operation. The reduction gear set 12 further improves the dynamic performance of the AGV.

[0029] This embodiment describes an AGV steering wheel. The reduction gear set 12 includes a second rotating shaft 13, a third rotating shaft 14, a third gear 15, and a fourth gear 16. The second rotating shaft 13 is rotatably connected to the top two ends of the third cavity 7, and the third rotating shaft 14 is rotatably connected to the bottom two ends of the third cavity 7. A first bevel gear 17 is disposed at the bottom of the first rotating shaft 10, and a second bevel gear 18 is disposed on the second rotating shaft 13. The first bevel gear 17 meshes with the second bevel gear 18. The third gear 15 is disposed on the second rotating shaft 13, and the fourth gear 16 is disposed on the third rotating shaft 14. The third gear 15 meshes with the fourth gear 16. The third rotating shaft 14 is connected to the wheel 2. Vertical power transmission is achieved through bevel gear drive. This structure can reduce speed, increase output torque, and ensure transmission smoothness and efficiency, meeting the steering drive torque requirements of the AGV under complex working conditions, and enhancing the load capacity and operational stability of the steering wheel.

[0030] The AGV steering wheel described in this embodiment has a first bearing 19 and a second bearing 20 respectively installed at the upper and lower ends of the first cavity 4. The outer walls of the upper and lower ends of the input shaft 8 are connected to the first bearing 19 and the second bearing 20 respectively. Specifically, the first bearing 19 and the second bearing 20 are installed at the upper and lower ends of the first cavity 4 to support the two ends of the input shaft 8, ensuring the coaxiality and stability of the input shaft 8 during rotation, reducing vibration and wear, thereby extending service life and improving transmission accuracy and system reliability.

[0031] The AGV steering wheel described in this embodiment has a positioning part 21 that protrudes outward from the center of the top of the housing 1, and the steering gear 3 is sleeved on the outer periphery of the positioning part 21. Specifically, the positioning part 21 that protrudes outward from the center of the top of the housing 1 is used to sleeve the steering gear 3, making the steering gear 3 more securely installed and more accurately positioned, avoiding offset or loosening, improving the response accuracy and assembly convenience of the steering system, and further enhancing the stability of AGV steering control.

[0032] Understandably, the first bearing 19 is mounted on the inner wall of the positioning part 21.

[0033] In this embodiment, an AGV (Automated Guided Vehicle) steering wheel is provided. A third bearing 22 is installed at the top of the second cavity 5, and a first tapered roller bearing 23 is installed at the bottom of the second cavity 5. The upper and lower ends of the first rotating shaft 10 are connected to the third bearing 22 and the first tapered roller bearing 23, respectively. Specifically, the third bearing 22 at the top and the first tapered roller bearing 23 at the bottom of the second cavity 5 support the first rotating shaft 10, enabling it to withstand both radial and axial loads, thus enhancing the stability and load-bearing capacity of the rotating shaft.

[0034] In this embodiment, an AGV steering wheel is described. The top two ends of the third cavity 7 are respectively equipped with a second tapered roller bearing 24 and a third tapered roller bearing 25. The two ends of the second rotating shaft 13 are connected to the second tapered roller bearing 24 and the third tapered roller bearing 25, respectively. Specifically, the second tapered roller bearing 24 and the third tapered roller bearing 25 at the top two ends of the third cavity 7 support the second rotating shaft 13. This structure effectively resists loads, improves the fatigue strength of the transmission components, ensures the long-term stable operation of the reduction gear set 12, and extends its service life.

[0035] In this embodiment, an AGV steering wheel is provided, with a fourth bearing 26 and a fifth bearing 27 respectively located at both ends of the bottom of the third cavity 7. The two ends of the third rotating shaft 14 are connected to the fourth bearing 26 and the fifth bearing 27 respectively. Specifically, this provides good rotational support, reduces frictional resistance, improves transmission efficiency, and helps maintain the smooth operation of the wheel 2, thereby enhancing the comfort and positioning accuracy of the AGV during operation.

[0036] In this embodiment, an AGV steering wheel is described. A cover plate 28 is detachably mounted on the outer side of the third cavity 7. The third tapered roller bearing 25 and the fifth bearing 27 are mounted on the cover plate 28. Specifically, the detachable cover plate 28 on the outer side of the third cavity 7 facilitates the maintenance and replacement of the internal gear components, significantly improving maintenance efficiency and reducing maintenance costs.

[0037] In this embodiment, an AGV steering wheel is provided with a sixth bearing 29 on the top of the steering gear 3. Specifically, the sixth bearing 29 is used to install on the AGV, which can effectively reduce the friction between the steering gear 3 and the external structure, improve steering sensitivity and response speed, enhance the support stability of the steering gear 3, prevent jamming or swaying caused by uneven force, and ensure the smoothness and accuracy of the AGV steering action.
