Abstract: A hub with a hub body, the hub body having two end units and a tubular center part, and the center part being disposed between, and received at, the end units. At least one end unit includes a tubular inserting portion onto which the center part having a tubular slip-on portion is pushed. The inserting portion and the slip-on portion overlap in an overlapping region.

Abstract: A wheel assembly quick release lever pivots against a thrust washer to apply a force along the length of an axle. The thrust washer is pressed toward a sleeve nut at the opposite end of the axle, which displaces the thrust washer relative to the axle, drawing the sleeve nut and a pair of compression rings toward one another deeper into conical cavities of dropouts. The radially outwardly facing surfaces of the compression rings firmly seat against the tapered cavities of the closed bore dropouts, and the radially inwardly facing surfaces of the compression rings firmly seat against the axle to provide resistance to rotational movement of the axle relative to the dropouts. The inboard surfaces of the dropouts seat against the load-bearing axle faces of the hub, which provides resistance to lateral movement.

Abstract: A hub device for a bicycle includes a hub case which is attached to a center of a wheel for receiving a load exerted from a rim to which a tire is fitted, and formed to have each inner diameter of both end portions larger than a diameter of a center portion, a sleeve with plural slits in a circumferential direction and a cylindrical shape integrally attached to the hub case at the inner diameter side, which serves to transfer the load exerted to the hub case to a shaft, a bearing for receiving the load exerted to the sleeve and rotatably supporting a whole structure of the wheel, a shaft for rotatably supporting the whole structure of the wheel via the bearing, and spherical washers attached to both end portions of the shaft.

Abstract: A wheel assembly, which is particularly applicable to bicycles, includes a hub, a pair of laterally spaced bearings, and is constructed to cooperate with a frame of a bicycle. The bearings include an outer race that is directly engaged with the hub. An inner race of each bearing is constructed to directly receive a portion of the bicycle frame such that the wheel is supported by direct interaction of the bicycle frame and the bearing members. Optionally, a hollow axle may extend between adjacent bearings to further enhance the lateral stiffness of the wheel assembly.

Abstract: A hub apparatus for a bicycle wheel with improved aerodynamic mechanism is provided. In one embodiment, the apparatus includes a hub body having a parabolic shape. The hub body is disclosed approximately about a center plane of the bicycle wheel and has a plurality of retaining holes for retaining one end of bicycle spokes.

Abstract: A wheel hub/universal joint assembly having an axis of rotation A constant velocity universal joint with an outer joint part, an inner joint part, and torque transmitting balls. The outer joint part has a first face toothing which engages a second face toothing provided at a collar on a sleeve portion of the wheel. Clamping means axially clamps the wheel hub to the outer joint part 22. The clamping means is axially supported on the wheel hub and the outer joint part 22. The ratio of the axial length BL of the wheel bearing 13 and the mean diameter DV of the face toothing is smaller than 0.63, i.e. BL/DV<0.63.

Abstract: A wheel hub-constant velocity joint unit in which a wheel hub (60, 90) with a passage opening (59, 89) that carries inner shaft teeth (44, 74) is tensioned with the outer joint part (46, 76) of a constant velocity joint (42, 72) on which a journal (53, 83) is formed with outer shaft teeth (54, 84), wherein inner shaft teeth (44, 74) of the passage opening (59, 89) and outer shaft teeth (54, 84) of the journal (53, 83) mesh in each other and a two-row wheel bearing (43, 73) is pushed onto the wheel hub (60, 90) that includes an inner bearing ring (64, 94) on which a front face (52, 82) of the outer joint part (46, 76) is supported directly, wherein the pitch circle diameter (TKD) of the roller bearing is greater than the pitch circle diameter (PCD) of the constant velocity joint.

Abstract: The present invention relates to a bicycle fork comprising an improved axle with non-round tapered ends affixed into dropouts with openings to match the axle ends through a taper-lock affixation for improving the torsional strength of the fork and facilitate ease of the axle installation. The improved axle consists of a first non-round end with interior female threads connecting an intermediate cylindrical portion which connects to a second non-round tapered end. An improved tapered split non-round nut having a cylindrical bolt possessing male threads lock the nut to the first end of the axle, wherein said bolt has an another preferred embodiment which connects a rotatable handle for ease of the axle installation.

Abstract: A quick release assembly includes a pivot pin and an axle secured to the pivot pin. A cam is pivoted to the pivot pin. A stop is movable between a first position detached from the pivot pin and a second position secured to the pivot pin inhibiting pivotal movement of the cam.

Abstract: A quick release assembly includes an axle, mounted to a hub, having an end, and a cam mounted to the end of the axle for pivotal movement. A fork is on the axle between the hub and the cam, and a follower is on the axle between the fork and the cam. A stop is movable between a first position detached from the end of the axle and a second position secured to the end of the axle inhibiting pivotal movement of the cam. A key and a detachably engagable keyway are also provided, in which the stop supports one of the key and the keyway. An extension of the follower projects into the fork preventing rotation of the follower relative to the fork.

Abstract: A hub and axle assembly for a bicycle includes a hub shell rotatably mounted on an axle extending along an axis. A rolling member is interposed between and cooperates with a curved surrounding race portion of a mounting sleeve member secured on the axle and a curved surrounding race member to serve as an anti-friction bearing. A tubular mount member has a tubular engaging portion to engage a left wall segment of the hub shell, and a tubular mount portion extending outwardly of the hub shell to be driven by a uni-directional driving sprocket wheel mechanism. A retaining member is disposed to prevent the mounting sleeve member from moving away from the rolling member.
