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:
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.
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. When the piston is moving into the second chamber reduction portion, the annular cushion seals channel fluid present in the work chamber to the second chamber reduction portion thereby providing a variable cushioning fluid pressure.
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:
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. The wear resistant coating is of particular use with vehicle wheels made from cast or forged aluminum, but may also be used by itself over steel wheels that have been pretreated to TT-C-490. It may also be used over anodized, electrocoated, or DOD-P-15328 wash primed aluminum as a standalone non CARC wear resistant coating.
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:
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:
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. The act of removing the safety ring so as to access and remove the nuts from the studs to disassemble the wheel, opens an air channel in communication with the tire interior so as to allow pressure to escape from the tire interior.
