Definitions

  • the hole is no more than 1 cm in diameter. This might lead to sudden collapse of the tyre itself, when the vehicle is loaded and travelling fast.
  • What makes an MCT unique is that it is collapse-proof, because it is composed of more than one compartment (mostly 3). When there is a puncture in one compartment, the other compartments continue bearing the load and the vehicle runs normally. At the same time an electronic warning device which is fitted in each compartment * alerts the driver at the dash board of low pressure in the affected compartment of the MCT. This will help the driver in fixing the narticular compartment at the next gas station.
  • MCT maps the constant fear of the driver of a sudden collapse of tyre while driving on the highway.
  • the lower one (D) is metalic It is smooth at internal side which is facing the wheel axis, and has three grooves (with standing edges (N) in between) circling all around rim (D) to dwell the other combination of three air tightening plastic pads (C) that have the same shape of the grooves of (D) i e they have flat bed in the middle with standing edges (L) that are to rest leaning on standing edges (N) of metal rim (D)
  • These plastic pads (C) are made of a few millimetres thick material of conventional internal car's tyre's tubes
  • the rim (D) is devided into 3 parts that have straight 3 slits along thickness of the rim, 1 slit between each two parts of the rim (D)
  • plastic pads (C) are to cover those 3 slits between the 3 parts of metalic ⁇ m (D)
  • Plastic pads (C) have edges (L) - detailed at page (5) figure (5) - that lay between walls of (MCT) air compartments lower walls (P), and standing edges (N) of metalic rim (D) in this way when the (MCT) compartments are full of air, the plastic pads are very well shutting rim (D) slits, and causing the whole combination to be perfectly airtight Rim (D) has as well side groove at the outer side where latches (E) hold rim (D) very firmly bolted to central metal unit (F) in a robust manner, as if all units are one structure
  • This third feature is the most important of the (MCT) Because the whole safety function of the (MCT) is carried out by this feature It is simply composed of tyre body which is manufactured of conventional strong plastic of car tyres and suitable internal reinforcing wires etc
  • the MCT body (A) has normal external surface (with straight tiny lineal grooves at these drawings But can be with any other design of grooves as usually the case in different tyres)
  • the weadth of the MCT could reach about 40 to 50 centimetres with 3 to 4 compartments
  • large airoplanes like Airbuses and Boengs could use about 10 compartments, and so on the cross section of those air compartments of the MCT are structurally almost round (see page 7/12 figure 7) They are seperated from each other by tyre walls that keep each two adjacent compartments independent of each other as if each is a complete tyre of it s own This is as such because of three aspects at this structure, lurking at the design of part
  • the inner standing metalic edges (N) of ⁇ m (D) are as strong as the most outer standing edge at the outer side of the ⁇ m Those inner standing edges go deep enough in & between the wall partition body (of which base part's cross section appears at figure (5), (7) & (8) with two legs fitting exactly on the (N) unit - one leg at the side facing each one of the adjacent compartments - almost resembling someone on a saddle) Those base legs of the inner MCT partition walls are continuous all around the (N) unit Moreover the (L) standing edges of the (C) plastic pad unit are placed between the (N) unit and the legs (P) (base part) of the partition walls And because of internal wire and reinforcement of the MCT the very foot part is strongly fitted to the bottom base of rim (D) Thus the air contents of every compartment of the MCT stays within Even when one compartments is punctured, the air content of the adjacent compartment has no chance to scape out
  • the mam feature illustrated here is how metalic rim (D) is disassembled into three sectors. There is a simple straight slit across the unit (from outer untill inner side) between each two adjacent sectors Thus when holding latches (E) are unbolted, and central unit (F) is removed, then rim (D) sectors can easily be pushed out of it's fitting place manually.
  • unit (Q) and unit (R) for the internal roots of the air blowing valves (J).
  • the plastic small ring base (R) is placed on plastic pad (C) part; which is pierced by the root of air blowing pipes (G).
  • unit (R) is dressed around the part of (G) which is peering inside the air compartment (B), and nut (Q) is screwed on top of that. This will cause unit (R) to be pressing strongly against the screw grooves under the nut. Thus shutting off any tiny space that might cause air leakage outside the air compartment.
  • the (D) ⁇ m diamer can be longer than usually the case; and the tyre body (A) can be shorter than usual; between the ⁇ m (D) and the surface that touch the ground. This can reinforce the strength - and power of functioning - of the tyre; without reducing the shock-absorbing competence than at normal single compartment tyre.

Abstract

L'invention concerne un pneu à plusieurs compartiments, composé de plusieurs compartiments d'air séparés par des parois de séparation placées entre les compartiments adjacents. Chaque paroi est constituée du même matériau que celui du corps de pneu, et est structurée sous forme d'une extension intérieure complète du corps du pneu. Au point de contact avec la jante (D) métallique de support, les parois se divisent en deux parties (P) . Ces deux parties (P) sont séparées l'une de l'autre par une distance suffisante pour les amener à s'adapter exactement sur le bord vertical de la jante (D), sous les deux côtés d'une paroi quelconque située entre deux compartiments d'air adjacents du pneu. La partie (P) sert à rendre chaque compartiment d'air adjacent complètement indépendant des autres compartiments d'air. De ce fait, s'il existe un défaut au niveau d'un compartiment, il n'affecte pas les autres compartiments.
