RIM OF WHEEL FOR PNEUMATIC TYRE Russian patent published in 1996 - IPC

FIELD: automotive industry; design of wheels for pneumatic tyres. SUBSTANCE: wheel rim has solid bead ring 1 and rim base 2 with mounting groove 3 and seat flanges 4 for beads of tyre 5. One of flanges terminates in non-detachable edge 6 and other, in circular groove 7 changing into flange 8 directed radially outwards. Distance from groove bottom 9 to flange outer diameter 10 is divided approximately into two equal parts by centering surface 11 for bead ring. Inner diameter 12 of bead ring is less than outer diameter 10 of flange 8 of rim base. Two through slots are made in relatively engaging surfaces 13, 14 of flange and of bead ring, respectively. Slots on rim base flange are made diametrically opposite. Angle between axes of symmetry of slots on bead ring is less than 180 degrees. Made on surface 14 of bead ring engaging with flange, between slots and symmetrically relative to slots, is stamped out cavity directed outwards with sizes providing its arrangement in through slot of flange. Ring 20 made of easily deformable material is located in rim base groove 7. Outer diameter of ring 20 is either equal to or is greater than inner diameter 12 of bead ring. EFFECT: enlarged operating capabilities. 5 dwg
