NONPNEUMATIC DEFORMABLE WHEEL Russian patent published in 2004 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to wheel which is not pneumatic, particularly, to deformable wheel which can be used instead of wheel with pneumatic tire on road vehicles. Proposed deformable structure 1 for vehicle designed for rolling around axle of rotation contains inner ring member 3, centered on axle, outer ring member 4 forming rolling race, said outer member being made flexible and nonstrechable and arranged outside in radial direction relative to inner member 3, and great number of radial bridges or spokes installed radially between inner member 3 and outer ring member 4. Each radial bridge or spoke is cable of setting constant force opposite to action of radial compression beyond the limits of threshold value. Circumferential length of outer member 4 is such that radial bridges or spokes are preliminarily loaded by radial compression force. Means are provided for stabilizing relative positions of inner member 3 and outer member 4 which limit amplitude of relative turning in circumferential direction between inner member 3 and outer member 4. Radial bridges or spokes are arranged between inner member 3 and outer member 4 so that their flexibility in meridional plane is less than flexibility in circumferential plane. EFFECT: improved reliability of wheel is operation. 13 cl, 11 dwg
