The bearing rotatably coupling the rotating body to the hub axle. The bearing includes an inner race, an outer race and a plurality of roller elements. The inner race has an axially facing portion abutting an inner abutment of the hub axle. The outer race has an axially facing portion abutting an outer abutment of the rotating body. The roller elements are disposed between the inner race and the outer race. The inner retainer is coupled to the hub axle and abuts an axially facing portion of the inner race. The outer retainer is coupled to the rotating body and abuts an axially facing portion of the outer race.

A wheel for a vehicle comprises a rim to support a tire and a wheel disc connected to the rim and configured to engage an axle hub of a vehicle. The wheel disc comprises one or more spokes extending outwardly from a center section of the wheel disc to the rim, each spoke being formed by a substantially planar curbside spoke member and a substantially planar inside spoke member, The curbside and inside spoke members are oriented transversely to each other and to a portion of the center section lying between the curbside and inside spoke members to define a triangle. A plane of the triangle is substantially parallel to a center axis of symmetry of the disc.

A lightweight wheel is provided, which includes a flange, a plurality of titanium alloy spokes and a carbon fiber rim, herein the flange is positioned at a middle part of the carbon fiber rim, the plurality of titanium alloy spokes are connected between the flange and the carbon fiber rim, and the plurality of titanium alloy spokes are uniformly distributed in pairs along the circumference; and one end of each of the titanium alloy spokes combined in pairs is fixed on the flange in a centralized mode, and another end is fixed separately at the carbon fiber rim, making the titanium alloy spokes combined in pairs a fan shape. An automobile is also provided.

A hub and spoke assembly includes a hub body having a first end and a second end. Projections are on each end. The projections are spaced apart from each adjacent projection about a rotational axis of the hub. Each projection comprises a base portion joined to the hub body and a support extending from the base portion to a free end. A plurality of spokes is provided. Each spoke comprises an elongated braided fiber having a loop at a first end and a second end configured for attachment to a rim. At least one spoke is joined to each support of each projection.

A spoke attachment flange for a bicycle wheel hub and a method for mounting spokes on the flange are disclosed. The flange has an annular body with a plurality of seats for housing enlarged spoke heads. At least one seat has an access opening configured to allow the insertion of the enlarged head in the seat. An outlet opening on the annular body is configured to allow a stem of the spoke to exit from the seat. The access opening and the outlet opening are connected through a connection channel that extends from the access opening towards the outlet opening without reaching a radially outer surface.

A wheel with flexible spokes, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength.

The present invention discloses a carbon fiber spoke and a manufacturing method thereof. The carbon fiber spoke includes a spoke body made of carbon fiber, a screw bushing that is fit and connected with rim and a nut cap bushing that is fit and connected with the hub. Two end parts of the spoke body are provided with solid joints. The outside surface of the solid joint is provided with a first tapered section. The screw bushing and the nut cap bushing are provided with penetrable mounting holes. The hole wall surrounding the mounting hole is provided with a second tapered section. The mounting hole of the screw bushing and the mounting hole of the nut cap bushing are respectively fixed to the two solid joints; the second tapered section of the mounting hole and the first tapered section of the solid joint are fit and connected together.

A bicycle wheel hub for mounting a brake disc in relation to a spoke-holding flange. The hub has a connection portion with a first annular sector that is axially external with respect to the spoke-holding flange and a second annular sector that is axially external with respect to the first annular sector. A circumferential groove axially arranged between the first and the second annular sectors.

The present disclosure relates to a hub apparatus and associated charging systems. In some embodiments, the hub apparatus includes (1) a housing assembly defining an internal space; (2) a shaft positioned to extend through the housing assembly; (3) a stator assembly fixedly coupled to the shaft; (4) a side cover fixedly coupled to the shaft and rotatably coupled to the housing assembly, the side cover having a base portion and a mating portion extending from the base portion; and (5) a pair of first connectors positioned through the mating portion. Each of the first connectors comprising a terminal end and a contact portion. The terminal end is electrically coupled to a battery assembly via a wire bundle fixedly coupled to the side cover. The contact portion is configured to electrically couple to an external power source so as to charge the battery assembly through a wired connection.
