A wheel assembly is provided that includes a structure defining a wheel portion configured to receive a portion of a tire. The wheel assembly further includes a structure of the wheel portion defining an air channel from a face of the wheel portion to an area that receives the portion of the tire, an end of the air channel proximate to the face being configured to receive a valve, where the structure is further configured to receive a corrosion mitigation device within the air channel.

The invention provides a rim for a braked aircraft wheel, the rim comprising an outer circular portion (103) terminated at its ends by flanges (106a, 106b) for receiving a tire, the outer circular portion being connected by a wheel disk (105) to a hub (104) for fitting on an undercarriage axle in order to rotate about an axis of rotation coinciding with a central axis (X) of the rim, the rim being designed to receive a tire on the outside of the outer circular portion and a brake on the inside, on one side of the wheel disk. According to the invention, the outer circular portion (103a) on the side of the wheel disk that is to receive a brake presents, in a plane containing the central axis of the wheel, a profile that has two slopes ?, ? relative to a direction parallel to the central axis on going from the wheel disk to the corresponding flange, and flaring towards the flange.

Provided is a tire including rims, beads each mounted so as to surround each of the rims, a side wall that is connected to the beads, a sub-tread that is formed on top of the side wall and is formed of a material having elasticity so as to have a changing curvature, and plural tread blocks that are arranged on the sub-tread such that the distances between the tread blocks change in accordance with the change in the curvature of the sub-tread.

A road wheel for a tracked vehicle includes a first rim half and a second rim half operatively connected to the first rim half. The first rim half includes at least a first portion that is angled away from the second rim half. The second rim half includes at least a first portion that is angled away from the first rim half. A hollow cavity is formed between the first portion of the first rim half and the first portion of the second rim half.

Disclosed are a vehicle wheel including at least; a wheel body having four plate coupling portions; plates coupled respectively to the plate coupling portions; plates coupled respectively to the plate coupling portions; air chamber brackets of a -shape each having an air chamber bracket hole formed on an upper surface thereof and respectively coupled the upper surface of the plates; and a hollow cylindrical hole bracket which is coupled through the air chamber bracket hole and moves up and down with rotation of the wheel body. As such, the present invention has the effects of significantly increasing the degree of freedom of design and the degree of freedom of resin selection due to the air chamber bracket formed by injection molding, and improving the strength by means of the air chamber bracket coupled to the wheel body.

The present invention provides a non-pneumatic tire that includes an attachment body (11) that is attached to a vehicle axle, a ring member including an inner cylinder (12) that is externally mounted on the attachment body (11) and an outer cylinder that surrounds the inner cylinder (12) from the outside in a tire radial direction, and a plurality of connecting members (15) that are arranged between the inner cylinder (12) and the outer cylinder in a tire circumferential direction and connect the cylinders to each other in a freely displaceable manner, wherein, between an outer circumferential surface (21) of the attachment body (11) and an inner circumferential surface (22) of the inner cylinder (12), a pressing member (20) that presses the attachment body (11) and the inner cylinder (12) in a direction in which they are separated from each other in the tire radial direction is provided.

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.

A wheel includes a first hoop attached to a second hoop about a circumferential interface. The first and second hoops form at least part of an enclosed box structure positioned circumferentially around the wheel and adjacent to an outboard side of the wheel. The box structure may be formed at least in part by circumferential projections of the first hoop and the second hoop. The wheel may also include a central hub that optionally includes spokes. In some embodiments, the central hub may form part of the enclosed box structure. In some embodiments, a first hoop portion and a second hoop portion may be integral or unitary, with a box structure integrally formed between the hoop portions.

A bolt together wheel assembly with deflation system includes an inner wheel half, an outer wheel half, a bolt cover ring, and a removable valve stem. Clamping bolts and clamping nuts secure the outer wheel half to the inner wheel half. Venting port plugs secure the bolt cover ring to the outer wheel half over the clamping bolts. Loosening one or more of the venting port plugs to access the clamping bolts opens a seal to a vent port within the inner wheel half and releases pressurized air from a tire on the wheel, ensuring that the tire is deflated before the wheel can be disassembled.

A wheel assembly comprising 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.
