Abstract: A self-inflating tire assembly includes an air tube mounted within a tire sidewall groove. The air tube is in contacting engagement with opposite angled groove surfaces surrounding the air tube. A segment of the air tube is flattened from an expanded diameter to a flat diameter by bending and compression of the groove in a rolling tire footprint to force air evacuated from the flattened segment along a tube air passageway. The sidewall groove extends into an annular, axially extending, sidewall surface such as an axially oriented surface of a tire chafer protrusion located in non-contacting relationship with the rim. The air tube is extruded from a rubber composition, the rubber composition comprising: a diene based rubber; from 0.25 to 5 parts by weight, per 100 parts by weight of rubber (phr), of a self-lubrication agent capable of migrating from the rubber composition to the groove surface and disposing on the groove surface as a liquid; and from 1 to 15 parts by weight, per 100 parts by weight of rubber (phr), of a vulcanization modifier for use in the second rubber composition include α,ω-bis(N,N′-dihydrocarbylthiocarbamamoyldithio)alkanes, bismaleimides, and biscitraconimides.

Abstract: A device for maintaining and changing the pressure in a is provided whereby the inner pressure space of the tire is connected through a pump to a pressure accumulator which, at its input and/or output into the inner pressure space of the tire, is fitted with at least one pressure control element. The pump can be a peristaltic pump in the shape of a deformable hose placed on the perimeter of the tire, fitted with an air inlet and an air outlet, while the air inlet and the air outlet are positioned on the perimeter of the tire distant from each other by a preset length, dependent on the deformation of the tire.

Abstract: A peristaltic pump chamber with shape memory for pressure adjustment in tires is provided and which is part of the tire or is adjacent to the tire wall or is a part of a vehicle wheel, in particular for tires with an inner tube, e.g. bicycle tires.

Abstract: All tire systems, including tire systems that include self-inflating devices, need to have the ability to regularly and reliably monitor and report vehicle and tire conditions for safety reasons. For a self-inflating tire, this can be accomplished by monitoring the operation of the self-inflation system, and assessing if it is consistent with a tire in good condition.

CPC classification number: B60C23/123 , B60C15/06 , B60C23/135
Abstract: A chamber is provided that works as a peristaltic pump for the pressure correction in the tire, which is a part of the tire or of an ancillary structure placed between the rim and the tire bead and is connected with the tire internal space at one end and with the external environment at the other end. The chamber is in the shape of a curved hollow channel, where at least one enclosing wall is at least partially formed by at least a pair of surfaces coplanar with the longitudinal direction of the chamber. When the tire is mounted on the rim, the pair of surfaces are pressed together thus hermetically closing the chamber. When the chamber is closed during rotation of the wheel, the surfaces can slightly slide on one another taking internal wall tensions onto themselves thus decreasing the possibility of wall damage through ripping.
