Abstract: The present invention relates to a runflat device arranged to be disposed within a wheel well of a wheel having a rim (5) for securing a tire (1), the device comprising a valve assembly (7, 8, 9, 10) arranged to be secured to the wheel and a plurality of part-annular components, said runflat device arranged to be drawn onto the wheel by a retraction mechanism when air pressure is applied to said valve (7, 8, 9, 10).

Abstract: The present invention relates to a runflat device (2), particularly, but not exclusively, a combined runflat and double sided beadlock that can be fitted to any size and type of wheel (1) regardless of the shape and depth of the wheel well (10). The runflat device (2) can be fitted using standard tools and tightened through manipulation of a valve assembly (52).

Abstract: 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.

Abstract: A wheel assembly for a vehicle includes a wheel having a first rim half and a second rim half with a reinforcement plate sandwiched between the rim halves. The rim halves and reinforcement plates are secured together to form an annular outer rim for receiving a tire. The rim halves have aligned central openings and aligned apertures for receiving fasteners for mounting a wheel hub on the wheel. A rock guard built into the reinforcement plate includes a plurality of rock guard formations each forming a shield which fills at least a major portion of any space between a respective recess and the wheel hub to block at least some debris from passing through the wheel while allowing airflow through the wheel.

Abstract: The present invention relates to a runflat device arranged to be disposed within a wheel well of a wheel having a rim (5) for securing a tyre (1), the device comprising a valve assembly (7, 8, 9, 10) arranged to be secured to the wheel and a plurality of part-annular components, said runflat device arranged to be drawn onto the wheel by a retraction mechanism when air pressure is applied to said valve (7, 8, 9, 10).

Abstract: The present invention relates to a protector shield for at least one sidewall of a motor vehicle tire, and to a wheel assembly for a motor vehicle incorporating this protector shield. The invention particularly but non exclusively concerns the fire protection against flames and/or said flammable substances, such as oil or Molotov cocktails, as well as a high solvent and/or acid resistance, especially in hostile environments. A protector shield of the invention is in a form of a curved ring designed to be mounted on a wheel rim receiving said tire and, according to the invention, the shield includes a fire protection part which defines an outer convex face of said shield and which comprises a cross-linked rubber composition which particularly exhibits flame retardant and heat resistance properties for imparting to said tire an improved fire protection against flames and/or flammable substances.

Abstract: A boat trailer roller wheel mounting system for carrying an insignia in a predetermined orientation is provided. Included is a closed-ended wheel bushing which carries indexing for mating with an indexed wheel support arm in a predetermined, rotational orientation. The roller wheel turns on and is held by the indexed bushing. A quick release retainer ring fixes the bushing to the support arm and acts as an inboard longitudinal movement stop for the wheel. The bushing indexing on the support arm transfers the rotational thrust created on bushing, due to the rotation of the wheel under a load, directly to the support arm and therefore eliminates this rotational thrust from acting upon the retainer ring. An end cap is formed at the closed outer end of the bushing and has an annular projection surface extending beyond the bushing surface to provide a longitudinal thrust surface against which the wheel hub can operate.

Abstract: This invention is directed to the repair of cast composite vehicle wheel hubs used specifically on trucks. Such hubs typically have a plurality of spokes extending from a boss with webs extending between the spokes. The hubs are cast of composite metal alloy material which cannot be repaired by conventional welding methods due to the metallurgical make-up of the hubs. Damaged outer spoke portions are repaired by fitting an annular band of material by removing a portion of each of the outer spoke surfaces. The band is secured to the spokes by using an intermediate bracket of weldable material secured by mechanical fasteners to the spokes of the hub.

Abstract: The invention provides a method of reinforcing a solid tire mounted upon a cylindrical hub such as, for example, a solid rubber fork lift truck tire. Tires have a solid flexible outer layer bonded to an inner cylindrical metal band. The hub is press fit within the band. In order to increase lateral stability or traction, operators often install tires of width greater than the size for which the hub is designed. The unsupported periphery of the band is subjected to impact loads and premature tire failure occurs. The invention provides a removable reinforcing ring which is press fit within the inner cylindrical surface of the metal band adjacent the hub. The outer cylindrical surface of the ring is of diameter to securely engage the band in operation but may be removed and reinstalled during normal maintenance by the same press which separates the tire and hub.

Abstract: Prior art truck hub has central boss with central axis, a plurality of spokes extending from the boss, and webs extending between the spokes. End faces of spokes commonly crack and by using method of repair the hub can be salvaged by removing from outer end of each spoke, a generally U-sectioned portion of end face and adjacent portions of spoke to form a pair of spaced shoulders on side portions of spoke. An annular rim or band is fitted on shoulders so that cylindrical inner face of band is adjacent generally axial edges of shoulders, and annular end face of band is adjacent radial edges of shoulders and partially annular edges of outer faces of spokes. Band is welded to ends of spokes to provide additional support for tire bearing rim.

Abstract: A wire wheel for fitting to a vehicle having a brake disc and a brake caliper extending around a portion of the edge of the disc, comprising a circular rim (10), a hubshell (15) having an inner mounting end and a smaller outer end and having an outer diameter somewhat smaller than normal, its radius being less than the radial spacing of brake caliper from the wheel center, and a plurality of spokes (12) connected between the rim and the hubshell supporting the rim concentric with the hubshell and with the hubshell located predominantly on the outer side of a plane which bisects the rim circumferentially. A supporting ring (2) is rigidly fitted to the inner mounting end of the hubshell, preferably with an interference fit and has a mounting face adjacent or coincident with the plane such that the caliper is clear of rotating spokes.

Abstract: A collapsible wheel rim structure adapted to support an inflated tire including a rim formed from pivotally mounted rim sections, and an internal plate support for the rim which fits into an internal track on the rim. The disc is formed from sections slidably mounted together which when fully extended enclose the area within the rim and support the rim. Supplementary rim support can be provided with collapsible cross-bars which fit into prongs on the internal surface of the rim so that the cross-bars extend across the internal diameter of the rim.
