Definitions

  • the main object of the invention is an arrangement of the adjacent layers of the upper sheets of the tyre cover.
  • a further object is the combination of the adjacent layers of the upper sheets thus arranged in combination with a particular construction of the layers of the carcass in the side walls of the tyre cover.
  • resistance to compression stresses set up in any direction whatsoever parallel tot-he rolling surface is. obtainedby arranging'within this tread bandor in the immediate vicinity of the latter twolayers of restraining elements e. g., metallic cords; each being covered with a continuous layer of rubber havin'gaveryhigh modulus ofelasticity. In each l'aye'nthe cord elements ⁇ areparallel toone another; but the direction of the elements-is different in both layers.
  • restraining elements e. g., metallic cords
  • the modulus of elasticity of the rubber, in which the wires, cords, or strips are embedded has a value greater than 350 (metric system) corresponding substantially to a Shore hardness greater than 72.
  • the invention comprises also a method of construction according to which the upper sheets, thus reinforced by a rigid core, which is flexible both in a transverse and radial direction, are combined with a carcass formed by one or more flexible layers of cords, parallel to one another and directed substantially according to the meridian of the tyre.
  • the reinforcement constructed in accordance with any of the embodiments described above should preferably be limited laterally in the vicinity of the edge of the tread portion and should not extend substantially beyond this edge in order not to interfere with the flexibility of the side walls.
  • Figure 1 is a plan view with parts exposed, and,
  • Figure 2 is a transverse section of the upper sheets of a pneumatic tyre in accordance with the invention.
  • Figure 3 is a section of the tyre showing the upper sheets and the meridial cord elements of the carcass.
  • Figures 1 and 2 there is shown a method of construction in which the reinforcement according to the invention, is formed of two layers each consisting of cord elements parallel to one another embedded in a layer of rubber having a high modulus elasticity and arranged in different direction in the two layers.
  • 5 and 6 indicate the two layers, and 7 and 8 the cord elements respectively of the layers 5 and 6, 9 being the rubber having a high elasticity in which are embedded the cord elements.
  • a tire casing comprising a carcass having flexible rubber-containing side walls, a rubber-containing ground; contacting tread portion on the outer periphery oi said carcass, a pair of superposed, directly adjacent, substantially parallel reinforcing plies within said carcass and substantially coextensive with said tread portion each ply comprising a plurality of parallel metallic cords e bedded in a layer of rubber having a modulus of elasticity of at least 350 and a shore hardness greater than 72, said layer having a modulus of elasticity substantially higher than the other rubber in the side walls and tread portion EQMLQQB and the cords in one ply extending at an angle to the cords in the other ply and to the median plane of said carcass.
