A hub for bicycles comprising a hub axle, a hub shell, a rotor, and a toothed disk freewheel including a pair of interacting freewheel components namely, a hub-side freewheel component and a rotor-side freewheel component. The freewheel components each comprise axial engagement components biased in the engagement position through a biasing device. The hub-side freewheel component is axially displaceably received in a threaded ring and non-rotatably coupled with the hub shell in the driving direction. The rotor-side freewheel component is non-rotatably provided at the rotor for transmitting rotational movement from the rotor to the hub shell in the engagement position of the two freewheel components. The threaded ring comprises a thread with a thread groove that extends along a helical line in an axial direction around a circumference of the threaded ring, where the helical line shows less than five full revolutions around the circumference of the threaded ring. The thread is screw-connected with a thread of the hub shell.

A hub for partially muscle-powered vehicles, including a hollow hub axle with a cylindrical inner through hole for the passage of a clamping axle, a hub shell rotatably supported relative to the hub axle by two hub bearings, a rotor rotatably supported relative to the hub axle, and a freewheel device with a hub-side freewheel component and a rotor-side freewheel component, each having axial engagement components for engagement with one another. The hub shell is rotatably supported relative to the hub axle in a rotor-side end region by a rotor-side hub bearing, and in an opposite end region of the hub shell by another hub bearing. The hub-side freewheel component is non-rotatably 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.

A wheel bearing assembly is disclosed that a bearing ring defining a first splined portion, a joint element including a second splined portion configured to matingly engage with the first splined portion, and a first retention assembly arranged radially outward from the first and second splined portions. The first retention assembly is configured to axially retain the bearing ring with the joint element.

A face spline coupling for transmitting torque between a wheel end unit and a driven shaft arranged in a longitudinal axis of a drive-wheel arrangement for a motor vehicle includes a first face spline formed in the wheel end unit and a second face spline formed in the driven shaft. The first face spline is generally perpendicular to the longitudinal axis and faces the driven shaft, and the second face spline is also generally perpendicular to the longitudinal axis and faces the wheel end unit. The first and second face splines are meshed together and detachably coupled by inter-fitting teeth of each of the first and second face splines. In addition, the teeth in each of the first and second face splines are formed in a helical configuration.

An axle assembly for a driving wheel of a vehicle allows a wheel-side joint and a shaft to be rotated separately from a boot while driving so as to prevent generation of friction noise of the boot. The axle assembly includes the shaft rotated by receiving driving force from a powertrain; an axle housing disposed to pass through a center of a steering knuckle connected to a steering apparatus; a wheel bearing mounted between the steering knuckle and the axle housing; a joint bearing mounted on an outer part of the shaft; and a boot unit configured to have a first end coupled to an outer race of the joint bearing and a second end coupled to an outer race of the wheel bearing so as to form a space filled with a lubricant outside the shaft.

Equipment including a rigid plate provided with a plurality of cutters configured to be impressed in sequence against a swaged annular collar of an inner ring of a wheel hub, the collar being formed with a first radial profile; the cutters sliding axially through the plate and towards a first face of the plate resting in abutment against the collar; wherein the first face of the plate is provided in the region of the cutters with a concave annular seat having a second radial profile configured to copy at least partly the first radial profile of the collar, the annular seat being configured to be passed through by the cutters during the step for impression against the collar and to contain any radial flow of the metallic material which forms the collar.

A silent hub structure includes a hub housing, an interlocking ring, a detent ring and a cassette base. The interlocking ring is installed inside the hub housing and has a central through-hole slot therein through which a detent ring is rotatably disposed therethrough. The through-hole slot is internally and circumferentially provided with a plurality of receiving grooves recessed at an equal distance therebetween on the internal wall. Each of these receiving grooves is disposed with a metal roller pin along the axial direction. The forward-rotating direction side of every receiving groove forms a clamping portion; a magnetic member is disposed in the interlocking ring near the clamping portion of each of the receiving groove separately, whereas the backward-rotating direction side of every receiving groove forms a releasing portion.

A bicycle hub includes an axle, a main body, a freehub body, and a clutch, which are engaged with the axle, wherein the clutch includes a first ratchet and a second ratchet. The first ratchet and the second ratchet are respectively engaged with the main body and the freehub body. The first ratchet has a first engaging surface, and the second ratchet has a second engaging surface facing the first engaging surface. The bicycle hub is characterized in that a minimum of number of first ratchet teeth on the first engaging surface is seventy-two, and a number of the second ratchet teeth on the second engaging surface is lesser than the number of first ratchet teeth. With such design, when the first ratchet is meshed with the second ratchet, the freehub body could stably drive the main body, and a total weight of the bicycle hub could be decreased.

A hub for partially muscle-powered vehicles, including a hollow hub axle with a cylindrical inner through hole for the passage of a clamping axle, a hub shell rotatably supported relative to the hub axle by two hub bearings, a rotor rotatably supported relative to the hub axle, and a freewheel device with a hub-side freewheel component and a rotor-side freewheel component, each having axial engagement components for engagement with one another. The hub shell is rotatably supported relative to the hub axle in a rotor-side end region by a rotor-side hub bearing, and in an opposite end region of the hub shell by another hub bearing. The hub-side freewheel component is non-rotatably 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.

A wheel-end disconnect assembly for translating rotational torque between an output shaft and a wheel hub of a vehicle driveline. A knuckle bracket at least partially supports the wheel hub. A clutch is operatively attached to the knuckle bracket, is disposed in selective torque translating relationship between the output shaft and the wheel hub, and is movable between: an engaged configuration wherein torque is translated between the output shaft and the wheel hub, and a disengaged configuration wherein torque is interrupted. An electromagnetic actuator is provided and has a slider selectively movable between a first stable position and a second stable position. The actuator is disposed in force translating relationship with the clutch such that movement from one stable position to the other stable position causes corresponding movement of the clutch between the configurations so as to selectively translate rotational torque between the output shaft and the wheel hub.
