A tire assembly includes a tire having an annular tread between and connected to outer edges of opposed first and second sidewalls. The first and second sidewalls terminate at radially inner edges defining first and second bead sections, respectively. The tire also has a first interior wall having one edge coupled to the tread and an opposite free edge. The first interior wall is positioned between and generally parallel to and spaced from the first and second sidewalls. A first annular spacer is positionable adjacent the first bead section between the first sidewall and the first interior wall on one side of the first interior wall. A second annular spacer is positionable on the opposite side of the first interior wall. The first and second annular spacers are configured to generally maintain a spacing of the first and second sidewalls and the first interior wall relative to one another.

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 (30) comprises a wheel rim (10) with a plurality of blocks (10a and 10b) and a tire (20) comprising beads (21 and 22) mounted against flanges (12 and 13) of the rim, the device comprising: a structure (31) for supporting the tire, which structure is to be mounted around the rim and is divided into ring sectors (32) in the form of an arc of a circle, surmounted by a casing (34) which is intended for supporting the tire when the latter is running flat and which has two projecting lateral portions (34b) partially covering lateral faces (32b) of the structure, and means (33) for locking the beads against said flanges, which connect the annular supporting structure to the beads. According to the invention, these lateral portions incorporate means (34c) 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.

A run-flat support system and method for installing the same are disclosed. In one embodiment, the run-flat support system includes a torque assembly removably coupled to a split wheel rim of a pneumatic tired wheel. Support segments are adapted for attachment to the torque assembly in order to support the pneumatic tired wheel in a flat condition such as an under-inflated condition or deflated condition. Lateral support structures, which may include the form of a wedge, are secured to the support segments to provide a bead lock between beads of the interior side walls of the pneumatic tired wheel and the split wheel rim.

The present invention provides a vehicle wheel system having an inner wheel half, an outer wheel half, a centering element, and a sleeve which are concentrically aligned with each other, where the centering element has a first bead lock for securing a first bead of a tire and where the sleeve has a second bead lock for securing a second bead of the tire, to enable a vehicle to continue to operate with a flat or deflated tire. For a heavier, military vehicle wheel system, a varied centering element is used in conjunction with segmented inner tire system.

An improved run flat tire and system for use with a two-piece or multi-piece wheel and tire to provide for continued operation of vehicles after tire deflation. Certain aspects of the invention include a plurality of arcuate sections releasably aligned and secured to each other for positioning around a wheel, wherein extended lip portions of each arcuate section extend laterally from the inner base portion of each arcuate section to limit lateral movement of the run flat device relative to the wheel.
摘要:
This improved bead locking apparatus and system is based on the provision of an expandable single and/or dual bead lock device with a bead compression ring that thrusts against the bead(s) of tire from the inside and is braced against and via the drop center of the wheel rim and/or an opposing bead compression ring. The aforesaid ring or rings are caused to press against the tire bead(s) via mechanical means actuated by a screw driver or similar implement. In single bead lock designs, the said implement can be inserted between the bead and rim on the side of the wheel opposite from that where the compression ring is located. In other designs, the said implement is inserted through an opening in the rim (which is preferably located in the drop center area of the rim) that is sealed with an O-ring, valve or plug. The bead lock designs of the invention may also be advantageously combined with a run flat ring in order to further facilitate the objects of the invention in assisting and enabling run flat capabilities.
摘要:
A tube-type tire to be mounted on the rim of a (e.g., spoke-type) wheel such as that commonly used by a bicycle or a motorcycle, whereby the tube-type tire will operate without a conventional inner tube and as if it were tubeless. The tire includes a main tire section that is seated upon the generally flat shelf of the rim and a pneumatic sealing ring having an inner tube that is seated upon the beadwell of the rim. An air chamber of the inner tube of the sealing ring is inflated to a greater pressure than an air chamber of the main tire section so as to isolate the air chamber of the main tire section from the rim and force the main tire section against the vertical lip of the rim. The sealing ring also has an outer inflatable liner that is located in surrounding engagement with the inner tube to separate the inner tube from the air chamber of the main tire section. The outer liner has one or more O-ring seals projecting outwardly from the side walls thereof and a centering lip projecting downwardly from the side walls. The O-ring seals are moved into sealing engagement with the inside of the main tire section when the air chamber of the inner tube is inflated and the liner is expanded. The centering lips of the liner are seated upon the beadwell of the rim to cause the liner to be automatically centered over the inner tube.
摘要:
A wheel well filler or runflat safety band having a band member with at least one break in it so as to enable it to be fitted onto a wheel. A link member connects the ends of the band member so as to bridge the break and thereby secure the band, in use, on a wheel. A wireless device is attached to the link member, which wireless device is remotely interrogatable in order to confirm the presence of the filler on the wheel.
摘要:
A run flat device for use in a wheel assembly comprises a wheel rim made of a plurality of blocks and a tire cover having beads mounted against flanges of the rim. The device includes an annular support structure for mounting around the rim to support the cover, the structure subdivided in at least two ring sectors to form the structure by juxtaposition in the circumferential direction thereof, and means for locking the beads against the flanges to connect the ring sectors to the beads. Each ring sector comprises at least two rigid support elements superposed in the radial direction of the structure and separated in pairs by respective rubber-based resilient layers, the layers adapted to shear based on a lateral force applied to the structure to enable the radially outer support element to be displaced axially relative to the radially inner support element.
