摘要:
A pneumatic vehicle tire including a carcass, particularly a radial carcass, a tread, and a belt-like reinforcement formed of at least two cord plies radially superimposed one above the other. At least one of the plies has rubberized metallic cord elements, and the other suitably has non-metallic cord elements. The cord elements cross each other from ply to ply, and the width of at least one cord ply is approximately equal to the width of the tread. The metallic cord elements, which particularly are made of brass-plated steel wire, further comprise a core and a mantle of wire, with the mantle including several twisted individual wires of equal size. The metallic cord elements in the cord ply comprise a core of a single wire filament, and a mantle comprising at least three single wire filaments. The mantle wire filaments respectively have a part which radially engages the wire filament of the core. The diameter of the wire filament of the core is smaller than the diameter of the mantle wire filament, which amounts at most to 0.28 mm. The center-to-center distance of adjacent mantle filaments is greater than the diameter of the mantle wire filaments.
摘要:
A method for determining the preferred direction of rotation of a vehicle tire including determining the direction of rotation of the tire in which the lateral structural force acting on the tire is greater. After this determination the tire is marked in a manner indicating the direction of rotation in which the lateral structural force is greater. In this way the tire may be mounted on a vehicle so that the conventionally forward direction of rotation of the tire is in the direction of greater lateral structural force so that the effect of the forces acting on the tire which tend to alter its direction of travel are minimized.An alternative method to accomplish the same result is to determine the direction of rotation of the tire in which the angular difference between the slip angle of the tire due to the lateral structural force acting on the tire and the slip angle of the tire due to the self-aligning torque acting on the tire is smaller and to mark the tire in such a manner that the tire may be mounted on a vehicle so that the conventionally forward direction of rotation of the tire is in the direction of smaller angular difference whereby the effect of the forces acting on the tire which tend to alter its direction of travel are minimized.This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
