REINFORCED BEAD OF RADIAL TIRE Russian patent published in 2004 - IPC

FIELD: tire industry. SUBSTANCE: invention relates to radial carcass tires, namely, to tires for use on trucks, prime movers, buses, trailers, etc, for which new design of tire beads reinforcement has been developed to improved their wear resistance. Proposed tire for heavy loads contains one radial carcass consisting of at least one layer of non-stretchable strengthening elements and secured in each bead on core forming a bend whose end is arranged at radial distance H_RNC from bead base. Each bead B is reinforced by at least two additional structures, first of which consists of radial strengthening elements and at least second of which consists of elements forming angle α, with circumferential direction 0^°≤α≤ 45^°. lying within first structure consisting of radial elements is wound around core outside said carcass and second structure is not wound around said core. EFFECT: improved wear resistance of tire exposed to heavy loads. 6 cl, 2 dwg
