VEHICLE WHEEL Russian patent published in 1997 - IPC

FIELD: transport engineering; light snow-and-bog vehicles on wide-section low-pressure tubeless tyres. SUBSTANCE: wheels has pneumatic tyre whose beads 2 have symmetrical seat surfaces 3. Tyre 1 is mounted on rim 4 welded to disk and provided with bevel seating flanges 6 with tilting angles pointed outwards from wheel center. Flanges 6 are made integral with seat rings 7 to which bead rings 9 are fastened by bolts 8. Valve is provided in rim 4 for inflating tyre 1. Tyre beads 2 are made with tilting of seat surfaces 3 relative to axis of wheel at angle of 0-15 degrees. Angle "A" between seating flange 6 of rim 4 and seat surface 3 of tyre bead 2 is equal to 145-175 degrees before deformation at tightening of bolts. EFFECT: enlarged operating capabilities, improved quality of tyre. 2 dwg
