Systems and apparatus for an oval O-ring groove for aircraft wheels may generally comprise an inboard wheel portion and an inboard O-ring groove. The inboard wheel portion may include an inboard rim located opposite of an inboard tubewell. The inboard tubewell may have an inboard mating surface located on an axially outward edge of the inboard tubewell. The inboard O-ring groove may be formed as a partial oval-shaped recess located on an outer edge of the inboard mating surface.

The invention relates to an aircraft wheel comprising a rim and a tyre (20) received on the rim, the rim comprising two parts (1; 2) assembled with one another by means of assembly bolts (5), one of the parts comprising a recess (3) in which is arranged a seal (4) which is interposed between the two parts, the wheel being characterized in that at least one of the parts comprises at least one duct (6) extending beneath the seal so as to establish a leakage path between on one hand a volume of gas delimited by the rim and the tyre, and on the other hand a space between the parts, the path being nominally closed by the seal when the bolts are tightened correctly but allowing gas to leak from said volume when the bolt associated with said opening is not tightened correctly or is absent.

A wheel assembly is disclosed, the wheel assembly including a rigid wheel including a radially outer rim wall presenting a polygonal shape with a plurality of outermost vertices connecting a plurality of planar faces, and a flexible tire mounted on the outer rim wall. The tire is supported by the vertices of the rim wall and is separated from the rim faces by a space, portions of the tire located between the vertices being configured to flex inwardly when subject to ground engaging pressure.

A quick release apparatus for a bicycle tire or tube is provided, which reduces time and effort spent in changing the tire or tube. A main wheel frame and a sub wheel frame are provided. These two frames with rim respectively can be assembled to construct a complete wheel frame set. When said main wheel frame connects with the sub wheel frame, it provides a complete rim with two walls for containing the tube. When said main wheel frame leaves said sub wheel frame, it generates a gap between these two frames for removing the tube easily.

A rim well with integrated flange made of fiber composite as well as to a method for manufacturing same. The flange is formed by inwardly directed protuberances of fiber layers of the rim well, wherein the fiber layers transition to the flange from the rim well without interruption of the fibers. The manufacture is carried out by depositing fiber material on a mold, which corresponds to the contour of the rim well and has a radially circumferential or segmented groove. The fibers are deposited such that the fibers of at least one fiber layer have protuberances directed into the groove. A multipart mold, which makes it possible to reduce the width of the groove and thus a deformation of the protuberances, is preferably used.

A method of manufacturing a wheel sub-assembly for a wheel of a very large vehicle, such as those used for mobile cranes, quarry excavation or transport of mined material. The method includes providing first and second cylindrical blank components and an annular disc blank; press forming the first blank component to form a one piece, axially outer rim portion; press forming the second blank component to form a one piece, axially inner rim portion; circumferentially Joining, the outer and inner rim portions to form an annular wheel rim having a base; machining the inside diameter of the wheel rim base; press forming the disc blank to form a press-formed disc; machining the outside edge of the press-formed disc; press fitting the press-formed disc to the wheel rim base at the machined inside diameter; and welding the press-formed disc to the wheel rim base at the machined inside diameter.

The invention is directed to a vehicle wheel (1) comprising a rim (2) for receiving a tire at its radially outer side (3) and provided with an edge along the circumferential of the rim at its radially inner side, a wheel hub connected to the rim via a support element, wherein the material of the rim and the support element are different, the support element provided with openings at its end facing the rim to receive a connecting element, the edge of the rim provided with openings in line with the openings of the support element and wherein the support element is connected to the rim via the connecting elements present in the openings in the edge and in the openings of the support element, wherein the opening in the edge is a radial elongated opening or is a indentation in the edge or the openings in the support element are radially elongated openings or indentations.

While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
