Description

Self-supporting tire of atmospheric internal pressure
The invention relates to a self-supporting tire of atmospheric internal pressure having a torus-shaped tread-bearing configuration prepared from an elastic material with a reinforcing casing consisting of at least one layer running in ordered direction, the said configuration having beads fitting at its internal part to the wheel rim, and with sidewalls between the beads and the tread. The essence of the self-supporting tire of atmospheric internal pressure described in the US patent No. 1,510,238 consists in steel springs embedded into the rubber material applied as an elastic casing, whereas bead rings are situated in its bead and tread. The drawbacks of this known solution are that it is heavy, its construction is too complicated thus its production is time-consuming and expensive, and it can be used only up to a certain speed limit. The objective of the present invention is to produce a simple, self- supporting tire of atmospheric internal pressure with an easy structure for use in vehicles. The task of the invention is thus to develop a self-supporting tire of atmospheric internal pressure having a monolitic structure for ensuring self- support. It was discovered that if a monolitic structure is created from a sufficiently elastic, and at the same time, retentive material, it is of self- supporting nature, preserving in the meantime also its elasticity. The above task was solved, as mentioned in the introduction, by a self-supporting tire of atmospheric internal pressure having a torus-like shape bearing the tread and having a reinforcing casing situated in an elastic material and consisting of at least one layer of ordered direction, further this configuration has beads fitting at its internal side to wheel rim, and sidewalls between the beads and the tread. The internal side of the configuration is laying on the wheel rim. According to the invention, the task has been solved so that the elastic material is a cross-linked synthetic resin, and the reinforcing casing layer(s) of ordered direction is (are) prepared from bead to bead from individual inorganic elementary fibres. At its rolling on the road, the tire gets continuously deflected, thus angled compression borders, i.e. edges are formed, along which strain peaks develop causing an accelerated fatigue of the tire. These strain peaks can be eliminated by eliminating the compression borders, i.e. the edges. For this reason, and for providing optimum load distribution, the embodiment is preferred in which the reinforcing casing layer(s) of ordered direction is (are) provided with continuous and/or intermittent slots. In order to eliminate damages on the sides and to ensure perfect contact between the tire and the wheel rim, an embodiment is preferred in which an external cover of a rubber-elastic material is applied on the tire. For providing better running performance, larger noise reduction and higher comfort feeling an embodiment is possible in which the tread consists of rubber. For better load distribution and for a more reliable fixing of the tread on the tire an embodiment is preferable in which at least one belt casing is present. In order to increase the self-supporting nature and the strength during use an embodiment is possible in which the beads and/or the sidewalls contain more reinforcing casing layers of ordered direction as compared to the other parts of the tire. For achieving simpler mountability, larger lateral loadability and increased power transmission, the embodiment is preferred in which the tire is glued onto the wheel rim. The self-supporting tire of atmospheric internal pressure according to the invention is described in more detail on the basis of the pictures of preferred embodiments. Figure 1 is a section of one of the embodiments of self-supporting tires according to the invention, Figure 2 is the above embodiment having continuously arranged slots, Figure 3 is the above embodiment with intermittently arranged slots, Figure 4 is another embodiment of the self-supporting tire of atmospheric internal pressure according to the invention glued onto a wheel rim, Figure 5 shows a further embodiment of the self-supporting tire of atmospheric internal pressure according to the invention mounted onto a wheel rim. As shown in Fig. 1 , the self-supporting tire 1 of atmospheric internal pressure according to the invention comprises an elastic material 3, reinforcing casing layer(s) 4 of ordered direction embedded in the elastic material 3 forming together a torus-shaped configuration. At the external perimeter of the torus-shaped configuration a tread 10 is developed consisting of rubber having an in se known tread pattern. At the internal perimeter of the torus beads 6 are situated by which the self-supporting tire 1 of atmospheric internal pressure according to the invention is connected to a wheel rim 5 (see Figs 4 and 5). The configuration has also sidewalls 11 between tread 10 and beads 6. Elastic material 3 consists of a cross-linked synthetic resin. The reinforcing casing layer 4 of ordered direction is developed from this elastic material 3 and from individual inorganic elementary fibres 7 arranged in it, where the individual inorganic elementary fibres 7 are regularly arranged from bead 6 to bead 6. In the embodiment shown in Figs1-3, there are several reinforcing casing layers 4 arranged on each other so that in different layers 4 the individual inorganic elementary fibres 7 are differently oriented, but in same individual reinforcing casing layers 4 the individual inorganic elementary fibres 7 are arranged in the same direction. Tire 1 is preferably surrounded from the outside by an elastic rubber material 9. The reinforcing casing layer 4 of ordered direction is provided with continuous slots 8, as is shown in Fig. 2. In the embodiment illustrated in Fig. 2, belt casings 12 are arranged. In the embodiment shown in Fig. 3 the reinforcing casing layers 4 of ordered direction are provided with intermittent slots 8. In this embodiment, beads 6 are formed from more reinforcing casing layers 4 of ordered direction as compared to the other parts of tire 1 , in which the orientation of individual inorganic elementary fibres 7 are identical in the same reinforcing casing layer 4, but layer by layer the orientation differs. In order to ensure larger loadability, the embodiment may be of advantage, in which not only beads 6, but also sidewalls 11 contain more reinforcing casing layers 4 of ordered direction. In the inside of self-supporting tire 1 of atmospheric internal pressure according to the invention shown in Figs 4 and 5, a relieving filler ring 2 is situated on the wheel rim 5. In the embodiment in Fig. 4, beads 6 are fixed with an in se known glue onto wheel rim 5. The self-supporting tire 1 of atmospheric internal pressure according to the invention shown in Fig. 5 is fixed on wheel rim 5 with clamping (snapping). The functioning of self-supporting tire 1 of atmoshperic internal pressure according to the invention will be described in the following. The self-supporting tire 1 of atmospheric internal pressure according to the invention is self-supporting owing to the cross-linked synthetic resin and to the reinforcing casing layer 4 provided with oriented individual inorganic elementary fibres 7 arranged in it up to a load limit corresponding to its dimensioning . This means that the tire does not require an internal overpressure for its regular functioning. Inside the self-supporting tire 1 of atmosheric internal pressure according to the invention, the relieving filler ring 2 arranged on wheel rim 5 makes an elastic, optimum transfer of the load from wheel rim 5 to the road surface via tread 10 possible even on bumpy, uneven roads producing large compression. Advantages of the self-supporting tire 1 of atmospheric internal pressure according to the invention are that its functioning is safe, as its safe operation is not influenced by bursts of the tire, its production is cost- effective, since it is produced from individual inorganic elementary fibres 7 not requiring extra processing, such as spinning or weaving, and tread 10 can be renewed quite cheaply.
