Abstract: An idler wheel for a tracked machine can comprise a cylindrical hub defining a central axis, an annular tread disposed concentrically about the cylindrical hub, a pair of side plates connecting the cylindrical hub and the annular tread, and a webbing connecting the cylindrical hub and the annular tread between the pair of side plates. A method for manufacturing an idler wheel comprises assembling a cylindrical hub, an annular tread, first and second side plates and at least one web.

Abstract: A bicycle disc wheel comprises a first disc panel and a second disc panel. The first disc panel has a first side outer surface and a first side inner surface and the second disc panel has a second side outer surface and a second side inner surface. The first side outer surface radially extends from a first disc panel outer perimeter to a center opening and the second side outer surface radially extends from a second disc panel outer perimeter to the center opening. The second side inner surface faces the first side inner surface. A brace is coupled to the first side inner surface and the second side inner surface that provide radial and axial structural support to the disc panels.

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: Reversible wheels are disclosed. Methods of making and using reversible wheels are further disclosed.

Abstract: A hermetically sealed wheel assembly which has been welding autogenously is provided, along with a method and system for welding the wheel assembly. The wheel assembly is made up of at least two components which are laser welded to each other without the use of filler material to create a hermetically sealed wheel assembly.

Abstract: A pneumatic tire of the semi-hollow type includes a casing having an uninflated inner volume and including an inner wall provided with a retaining bead and a convex outer wall forming the tread of the tire, the inner wall and the outer wall of the tire being connected by two annular borders. The inner wall of the tire is concave so as to surmount a convex outer wall of the peripheral seat of a rim of a wheel, this outer wall being provided with a peripheral slot adapted to accommodate the retaining bead of the tire.

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: A tire and rim combination includes a pair of circular rims with each of the rims including a radially extending flange member. The flange member can be releasably fit into the perimeter groove of the tire.

Abstract: A wheel assembly for a vehicle includes a wheel having a first rim half and a second rim half secured together to form an annular outer rim for receiving a tire. The rim halves have aligned central openings and aligned apertures for receiving fasteners for mounting a wheel hub on the wheel. In one embodiment, at least the central opening of one of the rim halves includes a plurality of spaced recesses around its periphery. A rock guard built into the wheel includes a plurality of rock guard formations each forming a shield which fills at least a major portion of any space between a respective recess and the wheel hub to block at least some debris from passing through the wheel while allowing airflow through the wheel.

Abstract: A hollow EVA foam tire structure includes a tire, a core and a rim. The core includes a plurality of sections substantially arranged into an annular shape and being hollow on both sides. A plurality of protruding block sections is disposed on the internal side of the flange section of the core extended from the accommodating space of the tire, and both sides of the tire are covered by the rim having two corresponding external flange surfaces at the external sides. Pointed splinters are disposed on the external flange surface and protruding block sections are protruded from the rim. Thus, the protruding block sections of the wheel core are alternatively and mutually engaged. Therefore, when the two corresponding rims are securely coupled, the pointed splinters of the rim can be pierced and fixed into the tire, and the internal side of the tire is embedded into the hollow section of the wheel core by a compressing force.

Abstract: A tubeless tire with combined wheel rim, wherein, left half wheel rim is locked with right half wheel rim to make an integrative wheel rim, inner rim of tubeless tire is gap shape and cover onto circular groove of wheel rim of tubeless tire, its features are as follows: to thicken side wall of tubeless tire properly, cover a -shaped section support ring onto open end of inner rim. When cover tubeless tire and support ring onto left half wheel rim, then lock up into a complete wheel rim with right half wheel rim, and position inner rim of tubeless tire into the formed circular groove, as fill air into tubeless tire, tire can keep more close with wheel rim.

Abstract: A wheel for a child's toy formed from a first and second section. The first section is made from a material having a Shore A durometer of 100 or less. The second section is disposed within the first section. The second section is made from a rigid material and provides structural support for the wheel.

Abstract: A structure for connecting a rim with a tire. The tire is formed with a central axial through hole. Multiple annularly arranged perforations are formed around the through hole. Each perforation is defined by a close circumference which is separated from the through hole by a separating section, whereby the circumference of the perforation is enclosed and the perforation simply axially passes through the tire. The rim is composed of a seat and a cooperative disc. The seat has insertion members respectively corresponding to the perforations of the tire. The insertion members are inserted into the perforations from one side of the tire, while the disc is mounted on the other side of the tire to connect with the seat.
