The invention provides a diameter-variable driving wheel, and relates to the field of wheel diameter-variable wheels, the diameter-variable driving wheel comprises a driving assembly and a wheel body, and the wheel body comprises a wheel surface assembly and a spoke assembly; the spoke assembly comprises two connecting plates and a plurality of spokes, the spokes are arranged in the circumferential direction of the connecting plates, the first ends of the spokes are hinged to the edges of the connecting plates, and the second ends of the spokes extend in the direction away from the connecting plates; the wheel face assembly comprises a wheel face deformation unit, and the wheel face deformation unit is hinged between the second ends, corresponding to the spokes, of the two connecting plates. The multiple wheel face deformation units are arranged in the circumferential direction of the connecting plate to form a wheel face. The driving assembly is constructed to drive the two connecting plates to move relatively so as to change the position of the spoke assembly and the state of the wheel face deformation unit. The wheel face deformation unit is of a negative Poisson's ratio structure and comprises a plurality of connecting pieces, and the connecting pieces are movably connected so that the wheel face deformation unit can be contracted or unfolded, and then the wheel diameter can be changed. According to the variable-diameter driving wheel, the energy consumption of the wheel is low.
