A hub for bicycles or the like including a hub shell which is rotatably supported relative to a hub axle, a rotor rotatably supported relative to the hub axle, and a freewheel device having two interacting freewheel components namely, a hub-side freewheel component and a rotor-side freewheel component. The two freewheel components each contain axial engagement components. The hub-side freewheel component is non-rotatably and axially fixedly connected with the hub shell. The rotor-side freewheel component is non-rotatably connected with the rotor and is movable in the axial direction relative to the rotor and the hub shell between a freewheel position and an engagement position. Rolling members are provided for defined accommodation in the hub-side freewheel component to support the hub shell relative to the hub axle. The hub-side freewheel component is connected with the hub shell through a multiple thread having at least two separate, axially spaced apart thread grooves.

A bicycle hub assembly comprises a hub axle, a hub shell, a sprocket support body, a first ratchet member, a second ratchet member, and a sliding member. The hub shell includes at least one first tooth. The sprocket support body includes a first helical spline. The first ratchet member comprises at least one first ratchet tooth and a second helical spline engaged with the first helical spline. The second ratchet member comprises at least one second ratchet tooth and at least one second tooth. The at least one second ratchet tooth is engageable with the at least one first ratchet tooth. The at least one second tooth is engaged with the at least one first tooth. The sliding member is provided between the sprocket support body and the second ratchet member in an axial direction parallel to a rotational axis. The sliding member includes a non-metallic material.

A bicycle rear hub assembly comprises a hub axle, a hub body, and a sprocket support body. The hub axle includes an axle through-bore that has a minimum inner diameter equal to or larger than 13 mm. The hub body is rotatably mounted on the hub axle about a rotational center axis of the bicycle rear hub assembly. The sprocket support body is rotatably mounted on the hub axle about the rotational center axis.

A sprocket support body is rotatably mounted on a hub axle of a bicycle rear hub assembly. The sprocket support body comprises at least ten external spline teeth configured to engage with a bicycle rear sprocket assembly. Each of the at least ten external spline teeth has an external-spline driving surface and an external-spline non-driving surface.

An axle assembly having a countershaft. The countershaft may be disposed in an axle housing. An axle shaft may be disposed in the countershaft. A first clutch may control rotation of the countershaft with respect to the axle shaft. A second clutch may control rotation of the countershaft with respect to the axle housing.

A hub for bicycles including a hub shell which is rotatably supported relative to a hub axle, a rotor rotatably supported relative to the hub axle by means of two rotor bearings, and a freewheel device having two interacting freewheel components namely, a hub-side freewheel component and a rotor-side freewheel component. The two freewheel components each include axial engagement elements and they are movable relative to one another in the axial direction between a freewheel position and an intermeshing engaging position. Rolling members are provided for defined accommodation in the hub-side freewheel component to support the hub shell relative to the hub axle. An attachment portion and a centering portion are configured in the hub shell and an attachment area and a centering area are configured on the hub-side freewheel component. The attachment area is connected with the attachment portion and the centering area is centered on the centering portion.

Bicycle hub includes a shell rotatably supported relative to a hub axle, a rotor rotatably supported by two rotor bearings, and a freewheel device having two interacting freewheel components: a hub-side freewheel component and a rotor-side freewheel component. The freewheel components each include axial engagement elements and are axially movable relative to one another between a freewheel position and an engaging, driving torque position. The hub-side freewheel component includes a threaded axial body section and is screwed into the hub shell. The hub-side freewheel component has an axial, annular surface on which the axial engagement elements are configured. The rolling members of a hub bearing show a defined accommodation inside the hub-side freewheel component to support the shell relative to the hub axle. The hub-side freewheel component includes a tool contour which couples to an adapted tool for releasing the screw connection of the hub-side freewheel component with the shell.

The present invention relates to a hub for a bicycle, having a hub axle, a hub sleeve which is mounted rotatably on the hub axle via a bearing arrangement, a driver which is mounted rotatably on the hub axle via a bearing arrangement and is coupleable to the at least one hub sleeve in a torque-transmitting manner, wherein the bearing arrangement has at least one axially inner bearing and at least one axially outer bearing. At least one fastening element is provided, which fixes at least the inner bearing of the bearing arrangement in its predetermined position on the hub axle by a local or sectional enlargement of the cross section of the hub axle.

An assembling method includes fitting an entire range of the guide portion to the stem section with a gap therebetween, and inserting a bolt from an outboard side through a bolt insertion hole formed in the hub wheel. In this state, a maximum inclination angle of the bolt with respect to the hub wheel is set to be larger than a maximum inclination angle of the outer joint member with respect to the hub wheel. The method also includes connecting the bearing and the constant velocity universal joint to each other by threadedly engaging and fastening the bolt into a bolt hole formed in the stem section.

A bicycle hub apparatus may comprise a hub body, a freewheel shell and an elastic spacer. The hub body has an axial hub axle, and an end of the hub body comprises an open-ended connecting space. A driving ring having a plurality of first driving teeth is installed inside the connecting space. The freewheel shell mounted on the hub axle of the hub body has an open-ended connecting recess, and a coupling ring received inside the connecting recess comprises a plurality of second driving teeth which are configured to engage with the first driving teeth. The elastic spacer secured in the connecting recess is coupled with an inner surface of the coupling ring. With the elastic spacer, the second driving teeth can firmly engage with the first driving teeth of the driving ring when a bicyclist pedaling in the forward direction.
