A bicycle hub assembly comprises a hub axle, a hub shell, a sprocket support body, a first ratchet member, a second ratchet member, a first biasing member, at least one receiving member, and a second biasing member. The first ratchet member is provided between the second ratchet member and the first biasing member in an axial direction. The at least one receiving member is provided between the first ratchet member and the first biasing member in a radial direction with respect to a rotational axis. The at least one receiving member includes a radially receiving part having a radially outer surface. The second biasing member contacts the radially outer surface of the radially receiving part to bias the radially receiving part toward the rotational axis in the radial direction.

A bicycle rear sprocket assembly comprises at least one sprocket having a total tooth number that is equal to or larger than 15. The at least one sprocket includes at least ten internal spline teeth configured to engage with a bicycle hub assembly.

A bicycle component for an at least partially muscle-powered bicycle with at least one freewheel unit including a freewheel component and a support unit and a spring unit, the freewheel component containing a tubular body section extending around a central axis and configured hollow showing a non-round outer contour for non-rotatable and axially displaceable coupling and a front surface with axial engagement components. The spring unit urges the freewheel component and the support unit apart in an axial direction of the central axis. The freewheel component, the support unit, and the spring unit form an assembly suitable for pre-assembly, and the spring unit is attached to the freewheel component and the support unit.

A hub or wheel assembly includes a retaining element, biasing element, and hand-maneuverable release mechanism. The housing includes an axle bore configured to receive an axle and a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end. The retaining element is within the conduit and is configured to operatively engage a groove in an axle. The biasing element is within the conduit and is configured to bias the retaining element towards the axle bore. The hand-maneuverable release mechanism is configured to displace the retaining element away from the axle bore.

A hub bearing assembly for the rotatable mounting of a soil cultivating disc (D) on a support shaft (A) of an agricultural machine, the assembly being provided with a hub bearing unit which in turn is provided with a flanged outer ring carrying two integral outer raceways for respective rows of rolling bodies, a flange fixed to the flanged outer ring for mounting a disc (D), and, for each outer raceway, an inner ring axially adjacent to the other inner ring, both of which can be engaged by the support shaft (A); and a sealing device mounted on a side of the hub bearing assembly opposite the side of the flange, composed of a first sealing stage and a second sealing stage arranged sequentially along the support shaft (A) and housed in respective seats formed directly in the flanged outer ring.

A bicycle hub structure has a hub member, a clutch set, a driving base and a sleeve. The thread angle of the outer threaded section of the driving base is greater than the thread angle of the inner threaded section of the driving central shaft, so that the driving central shaft and the external toothed coupling collar have a coupling state instantly which greatly reduces the actuation stroke of the clutch set, improves the smoothness of driving and the sensitivity of the hub member.

A sprocket support body comprises at least ten external spline teeth including a plurality of external-spline driving surfaces. The plurality of external-spline driving surfaces each includes a radially outermost edge, a radially innermost edge, and a radial length. A total of the radial lengths of the plurality of external-spline driving surfaces is equal to or larger than 7 mm. At least one external-spline driving surface has a first external-spline-surface angle. The first external-spline-surface angle ranges from 0 degree to 10 degrees. One tooth of the at least ten external spline teeth having a first circumferential spline size. The other teeth of the at least ten external spline teeth each have a second circumferential spline size that is smaller than the first circumferential spline size. A total number of the other teeth of the at least ten external spline teeth being equal to or larger than nine.

The invention relates to bicycle wheel hub structure, wherein two sides of wheel hub’s hub body are provided with wheel hub disc sets. The wheel hub disc sets are spaced with outer and inner hub discs. When assembled with several wheel spokes and a wheel frame, one end of the several wheel spokes is fixedly combined with the wheel frame and the other end of which is fixedly combined with the outer hub disc and the inner wheel hub respectively, so to disperse the stress generated by the wheel spokes, avoiding excessive force on the outer hub or inner hub. The outer and the inner hub discs are arranged at intervals, so that the spokes will be in contact with each other when assembled, reducing friction and affecting structural strength and service life, and achieving convenient structural use and good structural use function.

Presented are hybrid metal and fiber-reinforced polymer (FRP) composite wheels for vehicle wheel assemblies, methods for making/using such wheels, and motor vehicles equipped with such wheels. A wheel for a motor vehicle wheel assembly includes a wheel face with multiple spokes that are circumferentially spaced about and project radially outward from a central hub. The central hub rotatably attaches to the vehicle's body, e.g., via a corner module. The wheel face is fabricated, e.g., as a one-piece structure, from an FRP material. A wheel barrel, which circumscribes the wheel face, includes an annular rim that mounts thereon an inflatable tire. The wheel barrel is fabricated, e.g., as a one-piece structure, from a metallic material. Multiple overmold through holes and/or inset tabs are circumferentially spaced about the annular rim. The FRP material extends through and/or surrounds the overmold through holes/inset tabs and thereby mounts the wheel face to the wheel barrel.
