    1496498 Pneumatic tyres MICHELIN ET CIE (COMPAGNIE GENERALE DES ETABS MICHELIN) 19 Dec 1974 [21 Dec 1973] 54973/74 Heading B7C The inflation cavity of a pneumatic tyre is at least partly filled with cellular low density particles 6 carrying an inert lubricant, the filling hindering tyre deformation on puncture. The particles may be organic or inorganic polymers, glass based mineral foams, metal alloys or refractory materials or mixtures thereof. The lubricant may be fusable or non- fusable solids or liquid or mixtures thereof. Both the particles and lubricant material may increase thermal conductivity as the tyre temperature rises, and the vapour pressure of the lubricant may be such as to supplement inflation pressure. The particles may be contained in the tyre inner tube 4, in the inflation cavity of a tubeless tyre or in one or more bags 50, 51 insertable into the inflation cavity. Such bags are of flexible material and may be struck to tyre or may be thermo-fusible. Examples of particle, lubricant and flexible bag material are listed in the Specification.

    I
    The invention relates to automobile wheels with spikes, in particular k devices, allowing the vehicle to move with a damaged tire.
    The closest to the invention is an automobile wheel containing a rim and a tire, limiting a cavity filled with compressed gas, inside which particles of cellular material with a lubricant Gm are placed. The disadvantage of this wheel is that when a tire is punctured, it deforms strongly, and this reduces safety vehicle movement due to deterioration of stability and controllability.
    The aim of the invention is to improve vehicle safety when a tire is punctured.
    The goal is achieved by the fact that the particles fill the entire cavity of the wheel, and the particles are made spherical.
    of porous material, have an apparent specific gravity of less than 100 g / dm and a diameter of 1 to 8 mm, the lubricant is placed on the surface of 5 of these particles and is a mixture of water with polyglycol ethers and their derivatives, obtained by reacting ethylene oxide with compounds containing at least
    10 one free hydrogen atom; particles can be made of cross-linked polyolefins or from toothed rubber, or from polyurethanes, or from polyesters, or from cellulose derivatives, or from polyvinyl alcohol and formaldehyde-based foams, or from phenolic resins, or from urea-formaldehyde resins, or from polyimides or from polyactones, or from fluorinated polymers, or from polycarbonates, or from polyvinylcarbazoles, or from polyoxide-phenyl, or. from polysupan; particles can be made of unstitched polyolefins; particles of foamed polyolefins are made of polyacrylate or polyethylene8, or polypropylene, or aromatic polyvinyls, including polymers of styrene; Compounds containing at least one free hydrogen atom, representing aggilfeiols or fatty alcohols, or fatty acids. FIG. 1 shows a wheel cross section; in fig. .2 - wheel at the moment of its filling with particles, cross section; in fig. 3 - cola with, the cavity of which is filled with a bag of particles, gfodolny section. The wheel contains-rim 1, tire 2 and valve 3. At the same time, the cavity bounded by rim 1 and tire 2 is filled with spherical particles from cellular material that carry grease and compressed gas on their surfaces. In order for the wheel to function normally, the particles 4 must maintain their shape stability at (the working pressure of the gas filling the cavity of the wheel, as well as at temperatures up to 80 ° C. This is due to the fact that when the tire is damaged and the gas is exhausted from it, The load acting on the wheel at the same time heats up to approximately the aforementioned temperature. To ensure at least short-term sealing of the tire 2 in case of a puncture, the wheel cavity must be filled with particles k with a diameter of 1 to 8 mm. In order to ensure minimal impact on the basic characteristics of the wheel, as well as to ensure the visibility, the particles must be made of materials having an apparent specific mass of less than 100 g / dm. All these requirements are satisfied by a number of organic polymers, in particular polyolefins with or without a net structure of the molecule, for example, polyvinyl chloride, polyethylene, polypropylene and. their derivatives, including styrene copolymers (for example, acrylic) as well as rubbers, polyurethanes, polyesters, cellulose derivatives, polyvinyl alcohol foam and formaldehydes, phenolic and epoxy, urea-formaldehyde resins, polyimides, fluorinated polymers, polycarbonates, polymers, polyurethanes, polyurethane, polyurethane, formaldehydes, polyols, epoxy, urea-formaldehyde resins, polyimides, fluorinated polymers, polymers, polyurethanes, polyurethanes, polyurethane, polyurethanes polysulfones. Among these materials, foamed (porous) polystyrene meets the requirements mentioned above particularly well. However, inorganic polymers are also suitable, for example, silicones or inorganic foams on a glass base, as well as light porous metal alloys based on aluminum, magnesium and beryllium. The lubricant introduced into the cavity of the wheel is inert to the material of the inner surface of the tire at any temperature. In addition, the vapor pressure in the lubricant increases with increasing temperature, which makes it possible to increase the pressure in the cavity of the wheel after the puncture and, consequently, the heating of the tire. As a lubricant, mixtures of water with polyglycol ethers and their derivatives can be used, usually obtained by reacting ethylene oxide with compounds containing one or more free hydrogen atoms in the molecule, for example alkyl phenols, fatty acids and fatty alcohol. Particles J may be introduced into the cavity of the wheel, both before and after lubrication. Particles, due to their low mass, can be introduced into the wheel cavity by suction. For this purpose, in the rim 1 there is an opening 5 with a plug (not shown in Fig.) Into which the rods 6 are inserted, coming from the tank 7 with particles of k. On the other hand, the valve 3 of the wheel, designed to pump it up, is attached to the vacuum chambers /. 8. During the operation of the vacuum chamber 8, the particles C are sucked from the tank 7 through the hose b into the cavity of the wheel. After that, the opening 5 of the rim 1 is closed, and the wheel 3 is pumped with gas through the valve 3. To introduce particles k into the tubeless tire, one or more bags 9 of a soft, soft film, preferably low-melting, can be filled with them, then the bag 9 (bags) is placed into the tire 2 when mounted on the rim 1. inside the tire 2, it can be glued to the inner surface of the tire 2, for example to the surface under the treadmill.
    The present invention significantly improves the safety of the vehicle in critical situations, for example when a tire is punctured.
