The second input gear 14 meshes with the second gear shaft 15, and the first gear shaft 19 meshes with the third gear shaft 17. The second gear shaft 15 meshes with the fourth gear shaft 16, and the first gear shaft 18, the second gear shaft 15, the third gear shaft 17 and the fourth gear shaft 16 are meshingly installed in the first gear rack.

[0031] The first input gear 19 is connected to the first drive motor 8, and the second input gear 14 is connected to the second drive motor 9. The first pulley 20, the second pulley 21, the third pulley 22 and the fourth pulley 23 are respectively installed on the surface of the first gear rack 13.

[0032] The first drive wheel assembly 12 is composed of a first gear ring 25, a second gear ring 26, a first bearing bracket 28 and a second bearing bracket 31. The first gear ring 25 and the second gear ring 26 are installed at both ends of the first bearing bracket 28, and the first gear ring 25 and the second gear ring 26 are installed at both ends of the second bearing bracket 31.
