100% low floor vehicle independent wheel coupling driving device

The utility model relates to a 100% low floor vehicle independent wheel coupling driving device. The 100% low floor vehicle independent wheel coupling driving device is characterized in that the two ends of a shaft bridge device are provided with a driving independent wheel and a driven independent wheel, a wheel shaft of the driving independent wheel is provided with a driving gear box, and a wheel shaft of the driven independent wheel is provided with a driven gear box; and the driving gear box and the driven gear box are fixedly connected to a steering frame, the driving gear box and the driven gear box are connected through a coupling shaft, a traction motor is connected with the driving gear box, and meanwhile, the driving independent wheel and the driven independent wheel are driven to rotate through the coupling shaft. The 100% low floor vehicle independent wheel coupling driving device provided by the utility model has the advantages that the advantage condition of the independent wheels is guaranteed, the guiding problem of the independent wheel is solved through a mechanical coupling manner, a condition that the independent wheel has the same driving manner with the traditional rigidity wheel is guaranteed through the coupling shaft on the straight line and greater curvature, and the independent wheel smoothly passes through a curve rail with smaller semi-diameter through a differential mechanism.
