Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Please refer to fig. 1, fig. 2 and fig. 3, wherein fig. 1 is a schematic structural diagram of a driving wheel with stable operation according to a preferred embodiment of the present invention; FIG. 2 is a cross-sectional schematic view of the second wheel disc shown in FIG. 1; fig. 3 is a partially enlarged view of a shown in fig. 2. The action wheel that the operation is stable includes first rim plate 1 and second rim plate 2, two dead levers 3 of left side fixedly connected with of

first rim plate

1, 2 sliding connection of second rim plate are in two on the dead lever 3, two fixedly connected with fixed plate 4 between the one end of dead lever 3, the left side fixedly connected with driving motor 5 of fixed plate 4, driving motor 5's output shaft fixedly connected with threaded rod 6, the internal surface fixedly connected with thread bush 7 of second rim plate 2, first rim plate 1 with the surface of second rim plate 2 is provided with drive belt 8.

The outer surface of the threaded rod 6 is in threaded connection with the inner surface of the threaded sleeve 7.

Threaded rod 6 with first rim plate 1 and second rim plate 2 all are in same axle center, are in same axle center through the three, and when the rotation, the condition of barycenter skew can not appear, improves stability.
