    摘要: A reinforcing structure (10) for a tyre bead comprises several layers (18, 20, 22) built up by means of only one steel wire (12). The steel wire (12) has - in aged condition - a tensile strength lying above 3100 - 600xd MPa where d is the wire diameter expressed in millimeter, has a total elongation at fracture of maximum 2.5 %, and has an elastic elongation of at least 1.0 %. Substantial weight savings can be realised by means of this reinforcing structure.

    摘要: A steel cord (14) comprises a core filament (16) with a first diameter d₁, four or five intermediate layer filaments (10) with a second diameter d₂ and ten outer layer filaments (20) with a third diameter d₃. The intermediate layer filaments (10) surround the core filament (16) and the outer layer filaments (20) surround the intermediate layer filaments (10). The first diameter is substantially smaller than the second diameter and is substantially greater than the diameter of the circle (12) inscribed in the compact figuration of the cross-sections of the intermediate layer filaments (10) in case of no core filament. Such a steel cord has a full rubber penetration.
