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.

Abstract:

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.

International Classification:

B60C007/24

US Classification:

152396000

Abstract:

A multi-part automotive wheel comprises first and second wheel discs having first and second mating surfaces, respectively, where the first and second discs are to be joined to each other. An annular radial groove is disposed on one of the first and second surfaces for receiving an O-ring for sealing the first surface in respect of the second surface. The groove includes a substantially radial basewall and first and second sidewalls which extend from the basewall toward an intermediate section and from the section toward both edges of the groove, the edges defining a radial groove opening which is smaller than a distance between the sidewalls at the section such that an O-ring having a larger cross-sectional diameter larger than the opening will be retained within the groove prior to the discs being joined together. The basewall merges with the first and second sidewalls with rounded corners to reduce concentration of stress at the corners.

US Classification:

152415000, 152427000

Abstract:

A vehicle wheel assembly comprises a rim secured to a hub of a wheel; a tire secured to the rim; and a hollow stud having an air passageway. The hollow stud extends through a rim opening and has a first end secured to the hub. A lug nut is secured to the hollow stud at a second end. The first end is operably connected to a source of compressed air through the air passageway. A central tire inflation valve is secured to the rim. The rim includes a first internal passageway communicating with the air passageway and the valve, and a second internal passageway communicating with the valve and the interior of the tire.

International Classification:

B60C 29/02

US Classification:

152427

Abstract:

This invention describes a system to maintain equal pressure in a pair of dual tires, and also incorporates a valve mechanism that will prevent one dual wheel tire from going flat in the event the other dual wheel tire experiences a rapid air loss. Dual wheels are typically mounted on the vehicle hub with both wheel disc faces in direct contact with each other. To ensure equal pressure in both tires, this invention has air passageways machined into the wheels such that the air passageways meet at the interface between the wheels where the wheel disc faces are in direct contact. These junctions are sealed by a rubber seal or gasket. Both tires can then be inflated or deflated simultaneously through a standard air valve located on either wheel. Where a dual wheel arrangement requires the use of an intermediate piece between the dual wheels, air passageways can connect the two-piece wheels via intermediate air passageways going through the common intermediate piece. A dual pressure equalizing valve is connected to the air passageways and embedded into the wheels or intermediate piece.
