The invention provides an insert for supporting a pneumatic tire which is intended to support substantially the entire internal face of the pneumatic tire and has a radially internal face intended to sit atop a wheel rim that accepts the pneumatic tire, has at least one cavity designed to be inflated by a valve of the wheel which valve is independent of the insert, via inflation gas conveying means opening onto said radially internal face and into said at least one cavity and discharge means for discharging the gas from this cavity, said at least one cavity and these conveying and discharge means being formed in and/or on the insert, the inflatable cavity being formed by an internal volume within the heart of the insert or alternatively by a concave external surface of the insert.

Elastomeric insert for supporting a tire and mounted assembly incorporating it

The present invention relates to a run-flat device for attaching a tubeless mounted assembly for a motor vehicle, and to such a mounted assembly incorporating said device. A device () according to the invention includes: a tire support structure (), to be mounted around a rim having a plurality of pieces and comprising a reinforcing frame, and a bead lock means for locking the beads against the rim edge and connecting the support structure to the beads. According to the invention, the frame comprises an axial belt having at least one pair of ends opposite each other, separated by a connecting axial interstice, and connected therebetween by detachable connecting means () for locking the belt, the support structure being radially split on both sides on the right of each interstice to enable the manual mounting of the device inside the casing by the gradual insertion therein of the structure, temporarily free of the connecting means.

Run-flat device for a motor vehicle, mounted assembly incorporating same, and manufacturing and assembly method for same

The present invention relates to a flat-running device intended for equipping a mounted assembly without an air chamber for a motor vehicle, and to such a mounted assembly incorporating this device. This device () comprises a wheel rim () with a plurality of blocks (and) and a tire () comprising beads (and) mounted against flanges (and) of the rim, the device comprising: According to the invention, these lateral portions incorporate means () for holding the sectors, opposing the axial displacement of the latter under lateral forces in the event of a shock during running in the inflated state or in the event of running flat, so that these sectors remain surmounted by the casing.

Flat-running device for a motor vehicle and mounted assembly incorporating it

The invention provides a runflat device for a motor vehicle, the device comprising a ring for mounting inside a tire on a one-piece non-standard wheel rim that presents a drop center, an inner flange and an outer flange, said ring being made as at least two sectors each having a radially inner zone and a radially outer zone, wherein the sectors of the ring are independent of one another, and wherein each sector is fixed to the rim via its radially inner zone.

Runflat device for a motor vehicle including a ring made of at least two sectors independent of each other

A run-flat device for a motor vehicle, the device being designed to be fitted clamped on a standard rim having lateral flanges for holding the beads of a tire, wherein the device is constituted by at least two coaxial annular pieces engaged one on the other, the radially-inner piece being of relatively rigid material and forming an open ring around the rim, the radially-outer piece being based on an elastically deformable material and comprising a one-piece continuous surrounding the radially-inner annular piece and having an inside diameter that is substantially equal to or greater than the outside diameter of a lateral flange of the rim.

Device for motor vehicle running flat and method for mounting

A device enabling a motor vehicle to run on a flat tire, the device comprising a running ring made of elastomer and mounted tightly on the rim of the wheel inside the tire, the running ring being largely overdimensioned in radial height, in width or axial dimension, and in mass, and its radially-projecting annular portion is offset towards the inside of the vehicle to form protection for the occupants of the vehicle against the explosion of a mine triggered by passage of the wheel.

Device enabling a motor vehicle to run on a flat tire

A locking insert device for a tire chamber adapted to be fitted to a vehicle wheel provided with a tubeless tire mounted on a well or drop center rim, the device being designed to oppose the coming off of the beads of the tire from the rim in the event of a puncture of said tire, said device comprising a strip of rigid material shaped as a ring that is split parallel to the axis of the rim equipped therewith with an abutment member for a bead on one at least of its circumferential borders, the ring having a cross-section that correspond at least in part to the shape of the rim against which it is pressed and held stationary by fastening devices rendered operative after the ring has been placed on the rim.

Locking insert device for a tire chamber

A ring device for running with a flat tire and having articulated sectors is disclosed for a vehicle wheel equipped with a tubeless tire mounted on a one-piece rim with drop center, housed inside said tire and molding itself at least partially to the shape of the rim, the external surface of said ring being distant from the internal surface of the tread of the tire as long as the latter is in its normal operating condition, wherein said ring made from a composite material with a reinforced thermoplastic resin basis is formed so as to have in its part intended to come into contact with the rim drop center a stop lip for holding a bead of the tire in position, the other bead of which is subjected to the action of an elastomer wedge provided on the diametrical face of the ring opposite that carrying the stop lip, the articulated sectors being assembled together by mechanical fixing means providing positioning of the assembly of the ring and its component parts (elastomer wedge and stop lip) during actuation thereof.
