A subassembly includes a wheel hub and a constant velocity joint. The constant velocity joint includes a bell and the wheel hub is connected to the bell by high-pressure internal forming. Preferably, the wheel hub includes an axial projection disposed radially inside a connecting section of the bell, the projection interacting with the connecting section during the high-pressure internal forming process in order to connect the wheel hub to the bell. The projection is preferably configured to deform plastically and is connected to the bell in an interference-fit manner. Further, the wheel hub preferably provides an inner ring of a bearing unit and either the bell of the constant velocity joint provides another inner ring or a separate inner ring is disposed between the wheel hub and the bell.

A component assembly for a human-powered vehicle, the component assembly basically includes a member and a wire rod. The member includes a wall that has a first surface, a second surface opposite the first surface and an opening. The wire rod passes through the opening in the wall of the member. The wire rod includes a first portion located on the first surface side of the wall and a second portion located on the second surface side of the wall. The first portion includes an abutment portion that contacts the first surface adjacent the opening in the wall to suppress axial movement of the first portion of the wire rod through the opening in the wall with respect to an axial direction with respect to a center axis of the opening in the wall.

A spline connection having a hub with a toothing profile on the inner circumference, an axle journal having a toothing profile on an outer circumferential portion, a shoulder for axial support and/or abutment against the hub, and a tensioning device for axially bracing the axle journal with the hub. The hub has a constant toothing profile and the axle journal has a first portion and a second portion with different toothing profiles. The first portion is arranged on the insertion side to be further away from the shoulder than the second portion and has a constant toothing profile with play with respect to the toothing profile of the hub. The second portion is arranged on the shoulder side and has a toothing profile which has reduced tooth spaces compared with the first portion and which is play-free with respect to the toothing profile of the hub.

A sensorized hub bearing unit having at least one strain sensor for detecting, in real time, forces and moments applied to an outer ring of the hub bearing unit, in which a radially outer ring of the hub bearing unit is formed by a coupling of a first annular element and a second annular element arranged coaxially, the second annular element radially fitted and integrally inside the first annular element and at least one strain sensor arranged in line with an interface between the first annular element and the second annular element.

A disconnector assembly for a wheel hub transmission where the wheel hub transmission may have an input shaft that receives an input torque from a drive unit. The disconnector assembly may have a first coupling portion driven by the input shaft, and a connector having a second coupling portion and being axially displaceable between a first axial position and a second axial position. Each of the first and second coupling portions may have at least two engagement sections and at least one disengagement section positioned between the engagement sections. The engagement sections of the first and second coupling portions may engage each other when the connector assumes the first axial position. When the connector assumes the second axial position, at least one engagement section of the first and second coupling portion may be received in the disengagement section of the respective other of the first and second coupling portion.

A wheel bearing device (1) including: an outer member (2) on the inner periphery of which an outer-side rolling surface (2c/2d) is formed; an inner member (3) on the outer periphery of which an inner-side rolling surface (3c/3d) is formed; and a plurality of rolling bodies (41) interposed between the rolling surfaces (2c/2d/3c/3d) of the outer member (2) and the inner member (3). The wheel bearing device having a spline hole (3b) formed in a through hole (3h) of the inner member (3). The spline hole includes a guide groove (3G) formed on an inner circumferential surface thereof. A guide plate (8G) of a finishing broach (8) passes through the guide groove in the inner periphery of the spline hole (3b).

A bicycle freewheel assembly is provided which is capable of being readily and reversibly switched from fixed-gear to freewheel operation, without the necessity of removing the wheel from the bicycle. The freewheel assembly is mountable on pre-existing freewheel hubs.

The wheel bearing device having a spline hole (3b) formed in a through hole (3h) of the inner member (3). The spline hole includes a guide groove (3G) formed on an inner circumferential surface thereof. A guide plate (8G) of a finishing broach (8) passes through the guide groove in the inner periphery of the spline hole (3b).

A method for assembling a ring by shrinking the ring onto a shrink-fitting surface of a part, the shrink-fitting surface being turned radially away from a reference axis, the part having a free upper end and an inner wall extending around the reference axis turned radially toward the reference axis and extending axially while delimiting at least part of an axial cavity. The method including the steps of forming, on the inner wall, splines extending axially; shrinking the ring on the part so that a lower transverse face of the ring comes into abutment against a shoulder of the part. After the step of forming the splines and prior to the step of shrinking the ring onto the part, radial elastoplastic expansion of an upper portion of the part results in a widening of the shrink-fitting surface and of a portion of the splines.

A driving mechanism of a bicycle free-coaster hub includes a driving assembly, a clutch assembly, an epicyclic gear assembly, a resisting member, and forward drag and reverse drag members. The clutch assembly includes an output clutch unit disposed inner the hub and an input clutch unit disposed with the driving assembly to form a clutching or engaging state with the output clutch unit. The epicyclic gear assembly includes a sun gear coupled with the input clutch unit, a ring gear mounted on the hub, a planet gear carrier having a plurality of planet gears engaged with the ring gear and the gear portion of the sun gear. The resisting member is disposed between the sun gear and the hub axle. The forward drag member is disposed between the ring gear and the sun gear. The reverse drag member is disposed between the planet gear carrier and the hub axel.
