Definitions

  • This invention is related to vehicle tires, particularly those tire that do not need to be filled with air or any kind of gases in order to take the appropriate shape for running .
  • These tires are airless with no rims or side walls. They are composed of a rubber ring representing the tire's tread on ground, and another parallel ring connected with the wheel disc. There are pieces of hard rubber linking the two rings in a way to retain the shape of the tire and to support the weight of the vehicle. At the same time, this tire has an elasticity that allows compression when faced with obstacles on the road, then resuming its original shape after the obstacles' absence.
  • the causes of tire blow ups are several, too.
  • the first of which is the lack of tire care, tire and tire air pressure check, in addition to sharp objects causing tire punctures on the road.
  • Michelin Company embodied in an airless tire with no side walls and no need to be filled with air to take shape and consequently support the vehicle.
  • Michelin airless, rimless tire is composed of a rubber ring representing the tire's tread on the ground, and another parallel ring connected with the wheel disc. There are pieces of hard rubber linking the two rings in a way to retain the shape of the tire and to support the weight of the vehicle. At the same time, this tire has an elasticity that allows compression when faced with obstacles on the road, then resuming its original shape after the obstacles' absence.
  • claims 2 to 15 refer to specifically advantageous realization of a tire according to claim 1.
  • This invention has the advantage of a new design of the rubber linking between the two parallel rings of the airless tire.
  • These rubber joints may take the shape of straight parallel lines or the zigzag form of the letter (V) when connected repeatedly.
  • the new design of the rubber joints gives them the distinctive property of being independent neighbored joints at equal distances and ovally shaped with a circle in the middle having a united center with the oval shape and a united diameter with the short axis of the oval shape in addition to the tangency between the two shapes.
  • the inner circle pulls the sides of the oval shape to alleviate their compression, thus prolonging the life of the airless tire.
  • an embodiment relates to an airless, rimless tire for vehicles, composed of the tire's tread and a parallel internal ring linked to the wheel disc.
  • These means are made of two interrelating pieces: the first is oval in shape linking the tire's tread with the inner ring; the other is circular and having one united center with the oval linking means.
  • the circular linking means is connected to the rims of the oval means in the points that are vertically connected to the points that link the oval means with the tire's tread and the inner ring.
  • Figure 1 shows an embodiment of an airless tire according to the invention with a design of rubber connecting the parallel rings of rubber, and the projections of tire slipping prevention to be fixed in the wheel disc .
  • Figure 2 shows another embodiment of the airless tire with the new design of the rubber connecting the two parallel rings of rubber .
  • Figure 3 shows an airless tire with the new design of the rubber connecting the two parallel rings of rubber when the tire is compressed .
  • Figure 4 shows the new design of the rubber connecting the two parallel rings of rubber in normal status.
  • Figure 5 shows the new design of the rubber connecting the two parallel rings of rubber while compressed.
  • Figure 1 shows the tire 1 in general where the tire's tread 2 appears on the road, and the inner rubber ring 6 parallel to it and which connects with the wheel disc (not illustrated ) .
  • the rubber projections 5 can be seen on the inner rubber ring 6 from the side opposing the wheel disc . Opposite these projections, there are grooves on the wheel disc designed to prevent the tire 1 from slipping when the vehicle moves and the tire 1 revolves .
  • the rubber projections 5 can link between the two rims of the inner ring widthwise, and they can be small pieces no more than a few centimeters long with their number ranging from at least one to an unlimited number, but it is better to have two of them to ensure tire 1 stability in place, particularly when using the brakes to stop the vehicle .
  • Figures 1 and 2 show the rubber linking the inner ring 6 to the tire's tread 2, this rubber is composed of two pieces: one is the oval linking means 4, and the other is the circular support means 3 .
  • the linking means 4 is connected by one end to the tread 2, and by the other to the inner ring 6, whereas the support means 3 is connected with the linking means 4 by two sides only in a way that the center of the circular support means 3 unites with the center of the linking means 4, and consequently both become united in one axis .
  • Figures 3 and 5 show the effect of the vehicle weight on the linking means 4 and the support means 3 which compresses them both under its own pressure or under the pressure of a road obstacle .
  • the linking means 4 When the linking means 4 is compressed, it pulls the sides of the supporting means 3 outwards, making the circular shape of the support means 3 closer to an oblong shape . Consequently, the support means 3 pulls the sides of the linking means 4, preventing it from going oblong, thus maintaining a distance between the tire's tread 2 and the inner ring 6 and preventing the linking means 4 from being exposed to maximum compression, and thus protecting the wheel disc against damage .
  • Figure 4 shows the normal status of the linking means 4 and the support means 3 when there is no pressure falling on them, like the vehicle weight or the road obstacles .
  • Illustration ( 5 ) shows the linking means 4 while under pressure from the vehicle weight or a road obstacle with its sides going apart, thus making the support means 3 go as much oblong as to become closer to a straight line, and pulling the sides of the linking means 4 so as to retain its normal shape after the absence of the cause of compression, as in illustration ( 4 ) .
  • This new design protects the airless tire 1 from fast erosion and makes its presumed life longer when compared with previous technologies in the same field . It also protects the wheel disc from damage .
  • the linking rubbers composed of the tire's linking means 4 and support means 3, are distributed at close distances, but not joined, between the tire's tread 2 and the inner ring 6 in a way that each two successive linking means 4, when receiving compression, push each other reversewise ( towards retaining the linking rubbers to their normal status ) on contact when the tire 1 is compressed, enhancing the tire's power of tolerance and preventing its collapse .
  • linking rubbers composed of the tire's means of linking 4 and means of support 3, these rubbers are arranged at equal distances in a way that they do not touch each other when extending widthwise, thus allowing the tire lmore elasticity than when compressed .
  • the tire and/or elements thereof are made of rubber, especially the same material which is typcially used for manufacturing of tires.
  • rubber especially the same material which is typcially used for manufacturing of tires.
  • other materials including plastic or metal materials or any combination of rubber, metal and/or plastic materials can be used.
  • the tire is an airless tire, so that the tire not necessarily has to be inflated, however, it is also possible to in addition inflate the tire. It is possible to adopt the tire according to the invention to respective requirements, especially with respect to its flexibility and mellowness or softness, depending on the requirements and e.g. the weight of the vehicle.
  • the properties can be especially adopted to be suitable for light duty use, e.g. within the limits of cities, or for heavy duty use for vehicles inside and outside cities and possibly also on non-paved roads.
  • the tire can be installed on special wheel discs or rims, especially as no inflation is necessary, it is, however, also possible to install the tire on conventional wheel discs or rims according to the prior art, while inflation can optionally be provided, although not being necessary.
  • the tire according to the invention has therefore enormous advantages with respect to safe and secure utilization, while enabling a high controlability, there is no need for maintenance and the tire has a long life span, while it can be adopted to various applications.

Abstract

L'invention concerne un pneu pour véhicules qui est sans jante, de préférence sans air, composé d'une bande de roulement du pneu et d'un anneau interne parallèle relié au disque de la roue. Le pneu est doté de moyens de liaison, à proximité mais non reliés les uns aux autres, situés entre la bande de roulement du pneu et l'anneau interne. Ces moyens sont constitués de deux pièces en relation mutuelle : la première est de forme ovale et relie la bande de roulement du pneu à l'anneau interne; la seconde est circulaire et partage un centre avec les moyens de liaison ovales. Les moyens de liaison circulaires sont connectés aux bords des moyens de liaison ovales en des points qui sont verticalement connectés aux points reliant les moyens de liaison ovales à la bande de roulement du pneu et à l'anneau interne. Le côté de l'anneau interne est doté de protubérances en caoutchouc connectées au disque de roue et situées en face de rainures aménagées sur le disque de roue pour recevoir les protubérances en caoutchouc, ce qui empêche le pneu de glisser lors d'un freinage visant à arrêter le véhicule.
