The present invention discloses a resistance force control structure of driven pulley device, which is pivot mounted on a wheel of a driven pulley device, and primarily uses damping oil or a magnetic force to achieve a resistance effect. The magnetic force portion can also be added to a gear structure to present another configuration of a resistance force control structure to achieve change in magnetic force to increase the stabilizing effect of a wheeled frame. Moreover, an adjustable mechanism enables the user to control changes in the height of the damping oil level or magnetic force strength to control the rotational speed of a wheel.

The present disclosure may relate to centerless wheel assembly that includes a centerless rim including a first center point laying in a first plane generally defined by the centerless rim. The centerless wheel assembly may also include a centerless ring gear coupled to the centerless rim such that rotation of the centerless ring gear causes a corresponding rotation of the centerless rim. The centerless ring gear may include a second center point laying in a second plane generally defined by the centerless ring gear, and the first plane may be generally parallel to the second plane. Additionally, the centerless ring gear may be shaped to interface with a drive gear that drives the centerless ring gear.

A method for making the composite material wheel rim includes the steps of: configuring a plurality of inner lining chunks individually to the desired position where the spokes are to be mounted to allow the inner lining chunks to be integrated with an inner annular portion of the wheel rim, next, integrating the formed inner annular portion with an outer annular portion of the wheel rim to form a semi-finished wheel rim, and then, creating the requested threaded holes for connecting the spokes in the inner lining chunks of the inner surface of the semi-finished wheel rim subject to the requested amount and angles of the spokes. By the present method, the semi-finished wheel rim allows drilled, threaded holes subject to needs to fit different types of wheel hub units to increase the yield rate and reduce the inventory of the wheel rims.

A non-pneumatic tire assembly includes a non-pneumatic tire. The non-pneumatic tire includes an inner circumferential ring and an outer circumferential ring defining an annular space and a cylindrical space inside the inner circumferential ring. A plurality of partitions connect the circumferential rings within the annular space. A ground-contacting tread is located on the outer circumferential ring. A rim, including a plurality of pieces, is located within the cylindrical space. The non-pneumatic tire assembly further includes a hub that is removably connected to the rim.

A wheel assembly having two cylindrical bodies, each with a diameter approximately the same as the interior diameter of a tire. On the front body, are found an outer edge on one side and bolt receiving means on the opposite site and alignment holes. On the back body is found an outer edge, bolt receiving means that run across the entire length of the back body, are located on the interior of the body and are placed equidistant around the body. Each bolt receiving means aligns with a complementary bolt receiving means on the front body. The back body also has alignment pegs that fit into the alignment holes of the front body for proper alignment of the front and hack bodies. Holes on the hub, located on the front body permit placement of the tire and wheel assembly onto an axle of an automobile or other wheeled device.

The invention is directed to a vehicle wheel (1) comprising a fiber reinforced polymer rim (2) for receiving a tire at its radially outer side (3). The rim (2) comprises an outer rim flange (4), an outer rim seat (5), a frusto-conical plane (6) inclined at an angle a relative to the rotational axis (7) of the wheel of between 1 and 90 Q, an inner rim seat (8) and an inner rim flange (9). A wheel hub (10) is connected to the rim (2) via a metal support element (11). The support element (11) is connected with the rim (2) through at least one connecting element (12) which extends through a radially elongated opening (13) in the frusto conical plane (6) of the rim (2) and is received in the support element (11). The support element (11) may alternatively be connected with the rim (2) through at least three connecting elements (12) which extend through radially elongated openings (13) in the support element (11).

The invention relates to an equipment for a bicycle wheel. The equipment comprises at least one profiled wing-shaped projection adapted to be secured to the inner surface of the rim of the wheel.

A tool for working in fields includes a first flange and a second flange which mount one on the other, forming a wheel body. The first flange includes a central portion, a generally annular peripheral portion and arms which connect the central portion and the peripheral portion to each other. The second flange is homologous to the first flange. In the assembled state, the wheel body has a rim which is formed together by the peripheral portion of the first flange and the homologous peripheral portion of the second flange and a hub which is formed by the central portion of the first flange. The central portion of the second flange receives the hub which is formed by the central portion of the first flange.

The invention relates to an aircraft wheel comprising a rim and a tire (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 tire, 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.
