FIELD: machine building.SUBSTANCE: invention relates to machine building, particularly, to rubber-cord pneumatic element. Pneumatic rubber-cord element comprises cover layer rubber, rubber sealing layer, inner and outer bead rings and load-bearing frame layers. Edges of load-bearing frame layers wrapped around one bead ring in outer side of pneumatic rubber-cord element and other side ring towards inner cavity of pneumatic rubber-cord element.EFFECT: higher durability and reliability of pneumatic rubber-cord element due to reduced number of bends of layers of bearing frame is achieved.1 cl, 4 dwg |
