Definitions

  • the invention relates to a vehicle tire which is made of rubber or rubber-like plastic, preferably polyurethane elastomer and is provided with an outsole and side walls adjoining the outsole, the two side walls ending with a bead and the beads being clamped in a rim , furthermore the side walls are provided with a deflection part.
  • the vehicle tire according to the invention can be used on all public vehicles, passenger cars,
  • Trucks, etc. are preferably used.
  • the previously known vehicle tires are manufactured with a rubberized fabric substructure reinforcement.
  • the cords attached in the fabric substructure pull from one tire bead to the other and transmit the tensions caused by the internal pressure to the bead rings.
  • the tread formed from rubber which is directly connected to the roadway, is symmetrical in the crown of the tire above the fabric base, while the side rubber part covers the fabric base on the sides.
  • Another important part of the rubber tire is the bead formation reinforced with a steel ring, which ensures the direct connection to the rim.
  • HU-PS 195 149 Such a solution is known, for example, from HU-PS 195 149, with this rubber tire being between at least two layers of the A special rubber layer is arranged between the tread and the belt formed with cords, which enables more advantageous, less wear (abrasion) of the tread.
  • HU-PS 174 612 describes a similar structure, a small tread height and a large tread width, which relates to such a tire which can be used both with and without an air hose and whose base is made with radially directed stiffening threads is formed, which form a stiffening insert by intertwining.
  • the tread has a reinforced edge and in this area at least two such fiber braids are installed, the parallel threads of which intersect an acute angle including the circumferential direction of the tire, the ratio H / B between the largest Height H of the tire calculated from the edge of the tire and the maximum width B of the tire is at most 0.6.
  • Rubber tires reinforced with such a fabric substructure can be regarded as a spring with special properties, the load-bearing and elastic properties of which are essentially determined by the pressure of the air therein. 80% of the load-bearing function is exercised by the air content.
  • the primary task of tire construction is to maintain the amount of air required to carry the load, in such a way that it also assures the ability to absorb elastic deformations.
  • the service life and safety of the rubber tires depends to a significant extent on compliance with the operating parameters specified by the manufacturer (air pressure, load, etc.) and the hidden defects, structural irregularities of the rubber tires. For example, if the internal pressure in the running zone is reduced, the tire construction cannot relax sufficiently, as a result of which the tread bends inwards when it hits the road and, as a result, there is greater wear on the shoulder due to the concave bending the walking zone can even detach from the walking zone. Overloading has the same effects as the insufficient pressure.
  • the rubber tires are manufactured from a multiplicity of elements which consist of different materials (rubber and metal parts) with the aid of a manufacturing process which demands a multiplicity of different technological processes, mechanical and manual operations. From the complexity of the tire production it follows that in the individual production phases the deviation of any of several hundred parameters from a given value can influence the quality of the product. As a result, ensuring a constant quality of the products is an almost impossible task, but securing at least an acceptable level of quality can only be achieved by introducing extraordinarily complex and expensive quality assurance systems.
