[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1-3As shown, a steering assembly for an AGV trolley includes a flange plate 1, a steering motor 2, a turntable 3, an adapter plate 7 and a driving wheel 4. The steering motor 2 is fixed on the flange plate 1, and the turntable 3 includes an outer ring and an inner ring. The outer ring of the turntable 3 is fixed to the bottom of the flange plate 1, and the inner ring of the turntable 3 is rotatably fixed in the outer ring of the turntable 3. The driving wheel 4 is connected to the inner ring of the turntable 3 through the adapter plate 7. The steering motor 2 is connected to the adapter plate 7 and can drive the adapter plate 7 to rotate. During the steering process of the driving wheel 4, the steering motor 2 drives the adapter plate 7 to rotate, the lower part of the adapter plate 7 drives the driving wheel 4 to rotate, and the upper part of the adapter plate 7 drives the inner ring of the turntable 3 to rotate. The turntable 3 acts as a bearing, which can reduce the bearing capacity of the adapter plate 7, and then the adapter plate 7 can be set to be lighter and thinner, thereby reducing the overall installation height of the steering assembly, and at the same time reducing the overall weight of the steering assembly, saving materials.

[0018] In order to realize the steering motor 2 driving the adapter plate 7, it also includes a first steering gear 5 and a second steering gear 6. The first steering gear 5 is fixed on the output shaft of the steering motor 2, and the second steering gear 6 is fixed on the outer side of the adapter plate 7. The first steering gear 5 is meshed with the second steering gear 6. The steering motor 2 drives the first steering gear 5 to rotate, and the first steering gear 5 drives the second steering gear 6 to rotate, thereby driving the adapter plate 7 to rotate.

[0019] In order to achieve the decelerated rotation of the driving wheel 4, the diameter of the first steering gear 5 is smaller than the diameter of the second steering gear 6. When the first steering gear 5 rotates one circle, the second steering gear 6 has not yet completed one circle, thereby achieving the decelerated rotation of the driving wheel 4 and avoiding the unstable operation caused by the rapid rotation of the driving wheel 4.

[0020] In order to fix the outer ring of the turntable 3 and the second steering gear 6, the outer ring of the turntable 3 is fixed to the bottom of the flange plate 1 by a first bolt, and the second steering gear 6 is fixed to the adapter plate 7 by a second bolt.

[0021] In order to achieve the connection between the adapter plate 7 and the inner ring of the turntable 3, a protrusion 8 is provided at the lower part of the inner ring of the turntable 3. The protrusion 8 can extend into the inner hole of the connecting plate 7 and can be fixedly connected to the connecting plate 7. It can also be positioned by bolts or screws.
