Embodiment Construction

[0022] FIG. 1 shows an example of a radial aircraft tire 10 . As shown, the aircraft tire includes a pair of bead sections 12, each containing a bead core 14 embedded therein. One example of a bead core suitable for use in an aircraft tire is shown in US Patent No. 6,571,847. Those skilled in the art will understand that other bead cores may also be utilized. The aircraft tire comprises sidewall portions 16 extending generally outwardly in the radial direction of the tire from each bead portion 12 and a generally cylindrical tread portion 20 extending between the radially outer ends of these sidewall portions 16 . In addition, the tire 10 is reinforced with a carcass 22 extending annularly from one of the bead portions 12 to the other bead portion 12 . The carcass 22 includes an inner carcass layer 24 and an outer carcass layer 26 . In these carcass layers, generally four inner layers 24 are wound around the bead core 14 from the inner side of the tire toward its outer sid...

Abstract

A pneumatic tire having a carcass and a belt reinforcing structure wherein the belt reinforcing structure is a composite belt structure having at least one radially inner spiral layer and at least one zigzag belt reinforcing structure located radially outward of said spiral layer. The zigzag belt width is preferably narrower than the spiral layer.

Description

technical field [0001] This invention relates to pneumatic tires having a carcass and belt reinforcement, and more particularly to high speed heavy duty tires such as those used in aircraft. Background of the invention [0002] Pneumatic tires for high speed applications experience a high degree of flexing in the crown region of the tire as the tire enters and exits the contact patch. This problem is significantly exacerbated by aircraft tires, where the tires can reach speeds in excess of 200mph during takeoff and landing. [0003] As the tire rotates at very high speeds, the crown region tends to grow in size due to the high angular acceleration and velocity, tending to pull the tread radially outward. Counteracting these forces is the load of the vehicle, which only bears on a small area of ​​the tire, known as the contact patch. [0004] The current tire design drive is aircraft tires capable of high speeds, high loads, and reduced weight. The use of zigzag belt plies...
