Abstract
A filling for a puncture-proof pneumatic tire is formed by two half-toruses of elastomer or of rubber which are juxtaposed along an equatorial plane inside a tire cover and which are formed with a plurality of parallel channels of preferably hexagonal cross-section, the channels being parallel and separated from one another and positioned so that the thickness of material between adjacent channels is substantially constant.
Claims8
A filling for a puncture-proof pneumatic tire, the filling being designed to occupy substantially all of the internal space available inside a tire cover, and comprising a toroidal cushion of elastomer or of rubber that is formed with a plurality of parallel channels that are airtight and filled with gas, which channels are separated from one another and extend circumferentially around the rotational axis of the filling, wherein the channels are of polygonal cross-section with five or more sides and having rounded vertices, said channels being disposed in a staggered configuration relative to one another and being separated from one another by a substantially constant thickness of material.
A puncture-proof pneumatic tire mounted on a rim and comprising a tire cover the internal space of which is substantially occupied by a filling, the filling comprising a toroidal cushion of elastomer or of rubber that is formed with a plurality of parallel channels that are airtight and filled with gas, which channels are separated from one another and extend circumferentially around the rotational axis of the filling, the channels being of polygonal cross-section with five or more sides and having rounded vertices, said channels being disposed in a staggered configuration relative to one another and being separated from one another by a substantially constant thickness of material, wherein, in its free state, the filling has dimensions greater than the inside dimensions of the tire cover in order to be in compression when it is installed inside the cover.
