Abstract: An aircraft wheel comprising two half-wheels (1, 2) assembled together by means of bolt fasteners (10; 110) clamping together disks of the half-wheels, each bolt fastener comprising a bolt (11; 111) with an end forming a screw head (12; 112) and a threaded end (13; 113) for receiving a nut (14; 114), the wheel also being fitted with drive keys (20; 120) that are fitted to one of the half-wheels for driving brake disks in rotation, the wheel being characterized in that each drive key has a first end (23; 123) that is shaped to co-operate with the screw head of one of the bolts so that said first end is held and prevented from moving when the key is in place on the wheel.

Abstract: A tire assembly includes a tire having an annular tread between and connected to outer edges of opposed first and second sidewalls. The first and second sidewalls terminate at radially inner edges defining first and second bead sections, respectively. The tire also has a first interior wall having one edge coupled to the tread and an opposite free edge. The first interior wall is positioned between and generally parallel to and spaced from the first and second sidewalls. A first annular spacer is positionable adjacent the first bead section between the first sidewall and the first interior wall on one side of the first interior wall. A second annular spacer is positionable on the opposite side of the first interior wall. The first and second annular spacers are configured to generally maintain a spacing of the first and second sidewalls and the first interior wall relative to one another.

Abstract: A wheel structure for use in an engine-powered vehicle having an inner rim, an outer rim, an inner, partially truncated, cone-shaped element, a hub and a closing portion. The outer rim is sealingly attached to the inner rim, while the inner cone-shaped element is oriented with an opening at its truncated vertex end closer to the inner rim than its base and is then attached around the perimeter of its base to the perimeter of the outer rim. A closing portion with an opening at its center is provided which is attached at its perimeter to the perimeter of the inner cone-shaped element. The hub is connected on one side to the truncated vertex end of the inner cone and on the other side to the opening at the center of the closing portion.

Abstract: A vehicle wheel, which is divided in an axial direction of a tire into two pieces which are an in-side half wheel and an out-side half wheel that are connected to each other and fixed to an axle hub, includes wheel coupling bolts joining a mating surface of the in-side half wheel and a mating surface of the out-side half wheel together, and hub bolts joining the out-side half wheel and the axle hub together. The wheel coupling bolts and the hub bolts are respectively screwed into nuts from the out-side half wheel side.

Abstract: The application discloses a wheel assembly comprising a wheel comprising a main body, a substantially cylindrical wall, a front hub face comprising a central portion connecting a hub to an outer rim, wherein the front hub face comprises a socket for receiving a removable weight, wherein the socket or the weight is configured with a stop for preventing the weight from dislodging from the socket; a back face comprising a back central portion connecting the hub to the back outer rim; and the wheel assembly comprising at least one fastener for securing the weigh in the socket on the main body of the wheel.

Abstract: A wheel for an in-line skate or other wheeled vehicle is disclosed that may be modified to alter the rolling resistance of the wheel. The wheel may be disassembled to change a tire on the outer surface of the wheel to one made of a harder or softer material, and to insert or change a grease of a chosen viscosity into a chamber inside the wheel. The two changes may be utilized singly or collectively to help set the rolling resistance of the wheel. The wheel may be retrofit onto existing in-line roller skates.

Abstract: An aircraft wheel grease retainer for use in a wheel assembly having an axis of rotation, and further having bearings which are each located in a bearing cavity, wherein the bearing uses grease, which is introduced into the bearing cavity, wherein the wheel assembly is comprised of an outer wheel half assembly, and an inner wheel half assembly, wherein the grease retainer comprises a cylindrical retaining structure which spans from the bearings on the outer wheel half assembly to the bearings on the inner wheel half assembly, and two pliable interface rings. The cylindrical retaining structure has a centerline which corresponds to the wheel assembly axis of rotation, and further has an outer end and an opposing inner end, with a corresponding outer retaining flange and inner retaining flange which extend over the bearing cavities. The pliable interface rings seat on the cylindrical retaining structure, and interface between the cylindrical retaining structure and the wheel assembly.

Abstract: A wheel rim structure comprised of a first wheel member having a disk with a plurality of primary mounting holes and a rim portion; a second wheel member having a disk with a plurality of primary mounting holes and a rim portion; and a side plate having a disk with a plurality of primary mounting holes. The first wheel member disk is placed against the second wheel member disk and the side plate disk is placed against the first wheel member disk. The side plate, the first wheel member, and the second wheel member are then conjoined into a one-piece entity and, furthermore, mounted on a vehicle hub with threaded fastening components through the primary mounting holes.
