The freecoaster hub system for a bicycle also includes a transmission assembly at least partially mounted in the hub and operatively interconnected to the axle and the hub. The transmission assembly comprising a drive assembly and an engagement assembly, each of which operatively engage the axle and or hub.

A bicycle rear sprocket adapter comprises a plurality of external spline teeth and a plurality of internal spline teeth. The plurality of external spline teeth is configured to engage with a bicycle rear sprocket assembly. The plurality of internal spline teeth is configured to engage with a bicycle hub assembly. At least two internal spline teeth of the plurality of internal spline teeth are circumferentially arranged at a first internal pitch angle with respect to a rotational center axis of the bicycle hub assembly. The first internal pitch angle ranges from 10 degrees to 20 degrees.

A wheel bearing unit for a motor vehicle, having a wheel hub, a wheel bearing flange, and a wheel bearing for pivot mounting of the wheel hub on the wheel bearing flange. The wheel hub has a passage opening for mounting a shaft journal attached to the wheel hub by a screw connection element, and an inner toothing is formed, on an inner circumferential surface delimiting the passage opening, for rotationally fixed interaction with an outer toothing of the shaft journal, and the passage opening extends through a contact shoulder, which is formed so as to have contact with a contact surface of the screw connection element, with the formation of an orifice.

A method for manufacturing a hub unit includes: preparing a hub unit intermediate including an inner shaft, an inner ring fixed to an axial end of the inner shaft, and an outer ring rotatably arranged with respect to the inner shaft and the inner ring; preparing a magnetic seal member including a seal member and an annular magnetic member having no magnetic pole; and arranging the magnetic seal member between the inner ring and the outer ring of the hub unit intermediate. The method further includes: forming splines extending along the axial direction by cutting the inner circumferential surface of the inner shaft of the hub unit intermediate in which the magnetic seal member has been arranged; and forming magnetic poles in a circumferential direction of the magnetic member of the hub unit intermediate in which the plurality of splines have been formed.

A bicycle hub assembly comprises a hub axle, a hub body, a sprocket support structure, and a brake-rotor support structure. The sprocket support structure includes a first torque-transmitting profile and a first externally-threaded portion. The first torque-transmitting profile is configured to transmit a rotational force between the sprocket support structure and a bicycle sprocket assembly. The first externally-threaded portion is configured to threadedly engage with a first internally-threaded portion of a first lock member. The brake-rotor support structure includes a radially external surface, a radially internal surface, and a second torque-transmitting profile configured to transmit a rotational force between the brake-rotor support structure and a brake rotor. The second torque-transmitting profile is provided on the radially external surface.

An apparatus and methods are provided for a portal spindle assembly for a vehicle front suspension. The portal spindle assembly comprises a spindle portion that is rotatably coupled with upper and lower connecting arms. A leading-edge portion is rotatably coupled with a steering rod-end joint, such that moving the steering rod-end joint rotates the spindle assembly with respect to the upper and lower connecting arms. An inboard case and an outboard case support a pinion gear assembly that is meshed with an output gear assembly for communicating torque from a constant velocity joint to a front wheel coupled to the output gear assembly. The pinion gear assembly is aligned along a pinion axis disposed at an angle with respect to a hub axis of the output gear assembly. The angle facilitates a suspension geometry that provides a camber change of the front wheel that eliminates a change in track width.

A flanged inner ring for wheel hub bearings is disclosed, wherein a tubular supporting body for the bearing is coaxial with an axis (X), and is provided with a flange, transverse to the axis (X), is provided with a plurality of threaded through holes distributed around the axis (X), and is axially delimited by an outer annular mounting surface and by an inner surface axially facing an outer ring of the bearing.

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 vehicle wheel arrangement may have a wheel with a wheel hub and a carrier element for mounting the wheel on a vehicle part and/or for the arrangement of a power-transmitting unit. The wheel hub may have a joining portion, which in a joined state of the vehicle wheel arrangement corresponds with a joining portion of the carrier element. Surface profiles of the joining portions are configured such that, in the joined state of the vehicle wheel arrangement, the wheel hub and the carrier element are connected to one another in form-fitting fashion at least in a circumferential direction of the wheel hub axis. Furthermore, a method can be used to produce a vehicle wheel arrangement having a wheel hub comprised of fiber-reinforced composite and a carrier element.

The disclosure relates to a torque transmission assembly for a bicycle. The torque transmission assembly includes an adapter device and a driving body that is rigidly connectable to the adapter device in a torque transmitting manner. The adapter device has three support arms that extend with a radial direction component, and the driving body has a corresponding number of support cutouts. The support arms are received in the support cutouts forming a press fit. The torque transmission assembly is characterized in that the press fit of the support arms and support cutouts has two fitting planes, which are parallel to one another and to an imaginary plane containing the axis of rotation of the assembly. There is a clearance between the support arm and support cutout along the radial direction component.
