FIELD: transport.SUBSTANCE: invention relates to wheeled vehicles. Hub wheel comprises rim with tire, axle coupled with transport facility, and pressure source. Wheel rim is fitted on wheel axle to run thereon and sealed. Tire is fitted on wheel outer diameter and made of elastically strained material that allows varying tire cross-section. Radial holes are made in rim body, all over its circle. At least, one radial through delivery orifice is made in axle body and shifted from the center of gravity of the wheel to communicate with axle central bore while discharge orifices are arranged on opposite side to communicated with atmosphere. Pressure difference in tire cavity on opposite sides from center of gravity and asymmetric deformation of tire cross-section generate axle pushing force and rim turning force, that is, to drive the transport facility.EFFECT: decreased weight and friction, higher hub wheel efficiency.3 cl, 4 dwg |
