Abstract: 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.

Abstract: A system and apparatus for installing a central tire inflation (CTI) valve containing member into the hub bore opening of a wheel so as to be in communication with an air passageway hub port in the vehicle hub. Preferably, the CTI valve containing member includes a CTI valve sealed to a hub bore manifold with the hub bore manifold being mounted to the wheel disc and/or the vehicle hub. The hub bore manifold seals against the vehicle hub and the wheel hub bore surface (and/or the front face of the wheel disc). An air passageway in the manifold runs from the vehicle hub port to the CTI valve, and other air passageway(s) connect the CTI valve to the tire interior, such that air can travels from the vehicle hub to and from the tire cavity by way of the manifold and CTI valve.

Abstract: This invention teaches a method of coating a vehicle wheel to increase wear resistance which, in its preferred embodiment, includes the steps of providing a vehicle wheel and applying a wear resistant coating between/intermediate a primer and a topcoat. The wear resistant coating is applied to at least the tire bead flange of the vehicle wheel but may be applied to any area of the wheel. It is advantageously comprised of a MIL-P-53022B Type II lead and chromate free, corrosion inhibiting epoxy primer with an addition of 3% polytetrafluoroethylene (PTFE), and is formulated in such a manner so as to allow “wet on wet” application over a cured MIL-P-53084 primer. This application method improves adhesion through surface to surface covalent reaction between the polymerization of polyurethane top coat and the polymerization of intermediate epoxy polyamide wear resistant coating.

Abstract: This is an apparatus and system for integration of Central Tire Inflation (CTI) valve functionality directly into a wheel. The CTI valve may be attached to the wheel or integrated into the wheel. In addition, the CTI valve may have a valve body or the valve components can be installed directly into the wheel. An air passageway between the vehicle air source and the CTI valve and/or an air passageway from the CTI valve to the tire cavity can also be employed.

Abstract: In this invention ballistic resistant materials are integrated into a wheel for protection of the Tire Bead Bundle, protection of hardware, and protection of hub components. The Tire Bead Bundle can be protected by supplementing the existing rim flange with ballistic resistant material and/or by placing such material between the flange and the bead bundle. Further, for protection of hardware (including Manual Inflation or CTI Valves), ballistic resistant material can be incorporated over or on wheel hardware. Finally, ballistic resistant materials can be incorporated over or on the wheel hub diameter to reduce the risk of damage due to ballistic attacks.

Abstract: The instant invention is a pressure release safety system for a multi-piece wheel rim and tubeless tire combination, teaching designs for automatically relieving/releasing pressure as part of its disassembly. In this invention, fastening elements used to hold together portions of a wheel rim are provided with a blocking device or devices that prevents loosening and/or removal of fastening elements until said blocking device is first moved from a blocking position, where movement of the blocking device from its blocking position directly or indirectly opens or requires the opening of a pressure relief channel or channels—allowing, enabling and effecting depressurization of the sealed pressure vessel. When applied in the context of a tubeless two-piece wheel/tire assembly, the invention advantageously may include a blocking or safety device (typically in the form of a ring) that covers all or a critical portion of the nuts/studs that hold the two piece wheel together.

Abstract: This nut torque indicator cover includes a cover piece that is joined to an indicator piece. It is fastened to a nut/bolt assembly primarily by pressing it down onto and over the exposed threads of the bolt so that the indicator piece registers with the hex portion of the nut. A snap fit design is incorporated into the nut torque indicator cover such that the cover piece and indicator piece can rotate relative to each other. The cover piece fastens securely to the external threads of the bolt providing protection to the threads, while the indicator piece, secured by the hex flats of the nut, indicates the nut circumferential position, allowing an indication of any torque loss.

Abstract: This CTI Valve manifold of this invention creates a wheel-manifold-CTI Valve combination such that an air passageway coming from the wheel hub through the manifold brings air to the valve, and an airway from the valve through the manifold provides air to the tire cavity, preferably via an air passageway in the wheel. The manifold also allows for the CTI valve to deflate the tire, a typical operational requirement for central tire inflation systems.

Abstract: In this invention a tire protection attachment system utilizes adherent materials or mechanical attachments to the wheel rim to hold a covering of protective material adjacent the sidewall of a tubeless tire mounted on a circular wheel rim. The mechanical attachments are made to the outwardly flaring circumferential flange section adjacent the sidewall and/or to the transverse wall section of the wheel rim. Attachments to the flange section are characterized by the use of a clamping ring, a specially designed clip, and/or a circumferential retaining device with a variable circumference.

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 standardized wheel balance weight with a weight, a resilient clip attached at one end to the weight, and the opposite end of the clip split into at least two clip portions each defining a different unloaded gap dimension with respect to the weight to accommodate different rim flange thicknesses and contours. The opposite end of the clip may be trifurcated or split into four or more clip portions to define the two different unloaded gap dimensions. The opposite end of the clip also may be at least trifurcated into at least three clip portions to define at least three different unloaded gap dimensions with respect to the weight. Five clip portions may define the three different unloaded gap dimensions. The clip is self-retaining in all instances.

Abstract: A work cylinder having an internally-disposed, automatically-operated drain valve disposed in one or both ends of a housing having a cylinder bore formed therein. A reciprocally-movable piston divides the bore into first and second pressure chambers. A drain chamber formed in one or both ends has a movable plunger member disposed therein. A first passageway allows fluid from the pressure chamber to act on one surface of the plunger. A pilot valve is partially formed on a bottom portion of the plunger and opens when fluid pressure is exhausted from the adjacent pressure chamber. A bias spring acts on the plunger to prevent closing of the drain valve upon initial pressurization of the adjacent chamber. This initial pressurization assists in purging additional moisture from the chamber until a threshold level is exceeded to close the drain valve.

Abstract: A work cylinder having a piston of single-body construction and a cushioning arrangement integrally formed on the piston includes a cylinder housing having a chamber formed therein divided into first and second work chambers by the piston. First and second piston extensions extend into first and second graduated chamber portions formed at opposite ends of the cylinder housing. A sealing material, bonded to the exterior surface of the piston, exhibits a dual cup-shaped piston seal around the center portion and annular cushion seals on the piston extensions. The cushion seals are at an angle such that, when in contact with a first chamber reduction, a seal results. Additionally, in the opposite direction, the cushion seals act as a check valve whereby fluid pressure introduced to a second chamber reduction depresses the cushion seals and flows into the selected work chamber.

Abstract: A hydraulic cylinder having a locking device disposed in either, or both head ends which attach to the cylinder, has a piston reciprocally movable within a piston chamber formed in the cylinder. A stud member having a groove portion and a stud portion, secures to the piston for reciprocal movement therewith. The stud member axially moves within a stud bore formed in the head end such that, the stud bore acts as a variable volume stud chamber. A plunger member, disposed in the head end, is in fluid communication with the variable volume stud bore such that, movement of the stud member into the stud bore increases the fluid pressure, thus forcing the plunger out of contact with the stud portion of the stud member. When a predetermined pressure occurs, an outlet valve to the stud bore opens, reducing the fluid pressure and allowing the plunger to be urged into engagement with the groove portion of the stud member thus effecting a locked condition.
