An auxiliary wheel including a wheel hub and a tire, the wheel hub includes an outer wheel hub and an inner wheel hub and the tire is mounted on the outer wall of the outer wheel hub. The outer wheel hub and the inner wheel hub are detachably connected through a first connection component. When the first connection component unlocks the connection between the outer wheel hub and the inner wheel hub, relative rotation is generated between the outer wheel hub and the inner wheel hub with bearings disposed between the inner wheel hub and the outer wheel hub to reduce friction. Friction is reduced between the outer and inner wheels, thereby increasing the upper limit of the auxiliary wheel rotation speed. A nut and bolt arrangement is disposed in the nut groove to firmly fix the ring on the outer wall of the outer wheel.

A cast wheel having an alloy substrate includes a primary surface and a secondary surface. A first polymeric coating is applied to the primary surface and to the secondary surface sealing the cast alloy wheel within the first polymeric coating. An intermediate polymeric coating is applied over the first polymeric coating. The intermediate polymeric coating is coated with metal using physical vapor deposition with the metal being aesthetically distinguishable from the first polymeric coating. A third polymeric coating is applied over the metal. The third polymeric coating, the intermediate coating and the metal from the primary surface of the cast alloy wheel are removed aesthetically distinguishing the primary surface from the secondary surface. A fourth polymeric coating is applied over the primary surface and the secondary surface.

The present invention relates to a wheel rim extender device (1) removably mountable on a wheel (3) having a tire retaining rim (27) for engaging an outer surface of a tire (5). The device (1) has an annular member (11) for location adjacent a sidewall (7) of a tire (5) mounted on the wheel (3). The annular member (11) comprises an edge portion (33a, 33b) which defines an outer circumference of the annular member (11) and a support portion (35a, 35b), disposed radially inward of the edge portion (33a, 33b), for mounting on the wheel (3), wherein the edge portion (33a, 33b) has a greater flexibility than the support portion (35a, 35b). The invention also relates to the combination of a wheel rim extender device (1) and a wheel (3).

A traveling toy wheel whose simple configuration allows multiple devices to be enjoyed and can further change fine offsets is provided. The traveling toy wheel includes a first rim member to which a tire is mounted and a second rim member which includes a fitting portion into which a wheel hub of a traveling toy is fitted. Fitting holes as fixing portions are provided in one of the first rim member or the second rim member and elastic convex pieces as fixed portions are provided in the other of the first and second rim members. When the elastic convex pieces are fitted in the fitting holes, the first rim member and the second rim member are jointed relatively unmovably. A plurality of fitting holes are arranged at different positions, so that it is possible to easily adjust an offset of the wheel.

A traction board for insertion under a vehicle's tire for freeing the vehicle from a stuck condition includes an elongated board body and an end plate pivotally connected to an end portion of the elongated board body. According to a further aspect, a traction board includes an elongated board body and a finger pivotally connected to the elongated board body and pivotally extending below the elongated board body in order to prevent the elongated board body from sliding rearward.

A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

A non-pneumatic tire includes an inner ring, an outer ring, and a plurality of loops extending between the inner ring and the outer ring. The plurality of loops including at least a first loop and a second loop, wherein the first loop and the second loop are each in direct contact with both the inner ring and the outer ring. The first loop has a single reinforcement layer disposed therein, and includes a first extent that extends between the inner ring and the outer ring and a second extent that extends between the inner ring and the outer ring. The second loop has a single reinforcement layer disposed therein, and includes a third extent that extends between the inner ring and the outer ring and a fourth extent that extends between the inner ring and the outer ring. The second extent is in direct contact with the third extent.

A vehicle wheel structure includes a wheel and a wheel mounting member configured to be mounted on the wheel. The wheel mounting member includes a body portion that is fixed to an inner peripheral surface of an annular rim, the annular rim forming the wheel and supporting a tire on an outer peripheral surface of the annular rim, fins that are extended along an axial direction of the body portion on an inner peripheral surface of the body portion, and a weir portion that is extended on the inner peripheral surface of the body portion along a circumferential direction of the body portion to block air flowing along the axial direction in a state in which the wheel mounting member is mounted on the wheel and rotates together with the wheel.

A vehicle wheel structure includes a wheel that supports a tire and is assembled to a vehicle, and a wheel cover attached to the wheel. The wheel cover includes a main body, a pair of first and second engaging portions that is provided on the main body in a radial direction of the wheel and engaged with a first engaged portion and a second engaged portion of the wheel, and a restricting portion provided in the radial direction to restrict a displacement of the first engaging portion. The wheel cover attached to the wheel is detached from the wheel by displacing the second engaging portion configured not to be restricted in displacement by the restricting portion.

A wheel assembly is composed of multiple wheels, each featuring a hub with spokes and a main axle bore, and cross-roller sub-assemblies that include symmetrical axles and solid bushings, as well as peripheral rollers. The cross-roller sub-assemblies are overmolded with the wheel hub to form a peripheral axle ring. A method of assembling the wheel assembly involves creating the cross-roller sub-assemblies by overmolding the solid bushings with peripheral rollers, and then placing these sub-assemblies in a mold to form the peripheral axle ring. Alternatively, the pre-roller assemblies may be overmolded directly with the wheel hub to form the peripheral axle ring.
