Further, eccentric gear is equipped with the extension back shaft, wheel drive gear and wheel all are equipped with central through-hole, the central through-hole of wheel drive gear and wheel is worn to locate by the extension back shaft.

Furthermore, the eccentric gear and the extension support shaft are designed in a split mode, a key groove is formed in the inner wall of a central hole of the eccentric gear, a clamping key matched with the key groove is arranged on the side wall of one end of the inner side of the extension support shaft, and a polished rod supporting portion penetrating through the wheel is arranged at the other end of the inner side of the extension support shaft; the extension supporting shaft and the eccentric gear are in butt joint with each other into a whole through the matching of the clamping key and the key groove.

Furthermore, a limiting wear-resistant sliding sleeve is arranged between the wheel and the extension supporting shaft.

When the automobile body needs to be driven to advance, the wheel driving motor is started, and the wheel driving motor drives the wheel driving gear through the first reduction gear set, so that the wheels are driven to rotate.

When the automobile body needs to be rocked, the rocking driving motor is started, the rocking driving motor drives the eccentric gear through the second reduction gear set, the rocking shaft rotates along with the rocking of the eccentric shaft hole of the eccentric gear, and the automobile body supporting piece is fixed on the rocking shaft, so that the rocking effect of the automobile body is achieved.

Compared with the prior art, the invention has the advantages that: the invention adopts two driving motors to drive two rows of reduction gear sets simultaneously, has two output ends simultaneously, and acts on wheels and axles respectively, thereby realizing two functions of driving the vehicle body to walk and rotating the axles to swing the vehicle body, and being simple and firm, low in cost and convenient to implement.
