Abstract: A method including the steps of forming an inner ring of the wheel hub, as the joining of a spindle and an insert ring fitted onto the spindle, on the side of a first end of the spindle; axially blocking the insert ring on the spindle by plastically deforming the first end of the spindle so as to form an upset collar therewith, which axially protrudes from the insert ring; and once the step of forming the upset collar has finished, frontally obtaining on the collar, on the side opposite to the insert ring, a frontal toothing by axially impressing on the collar one or more knives in sequence, carried in an axially sliding manner by a plate.

Abstract: A bearing-hub assembly having a rolling bearing provided with a stationary radially outer ring, at least one rotatable radially inner ring and at least one row of rolling bodies is provided. The bearing-hub assembly includes a light alloy hub, provided with a flanged portion and a cylindrical housing. The cylindrical housing is axially located inside the radially inner ring and is provided with an external lateral surface having a complementary shape with an internal lateral surface of the radially inner ring.

Abstract: A hub for a motor vehicle wheel provides a cylindrical portion that extends in an axial direction, and a flange extending in a radially outer direction from an axially outer end of the cylindrical portion. The hub includes a core of metallic material which extends into the cylindrical portion and in the flange of the hub, and a covering body of plastic material applied over the core.

Abstract: A hub unit includes a hub of light material forming a cylindrical portion, a flange and a radial recess having a surface facing the flange, and two bearing rings axially aligned around the cylindrical portion of the hub; a sleeve locking device is radially interposed between the cylindrical portion of the hub and the bearing rings, and comprises a retaining portion engaged in the radial recess of the hub, a terminal edge which preloads the bearing rings, and one or two cuts extending in an axial direction.

Abstract: A hub unit is provided with a hub made of an aluminum alloy for plastic processing, which forms, in a single piece, an axially extending cylindrical portion and a radial flange; two bearing rings are mounted axially aligned around the cylindrical portion, an axially inner edge of the cylindrical portion is plastically deformed in a radially outer direction against the axially inner bearing ring.

Abstract: A method including the steps of forming an inner ring of a wheel hub, by joining a spindle and an insert ring fitted onto the spindle, on the side of a first end of the spindle; axially blocking the insert ring on the spindle by plastically deforming the first end of the spindle so as to form an upset collar therewith, which axially protrudes from the insert ring; and once the step of forming the upset collar has finished, frontally obtaining a frontal toothing; the finished collar has, in the part of the collar which axially protrudes from the ring, a predetermined geometric shape which substantially defines, in the radial section, a scalene triangle having the base facing the upset ring and the vertex opposite the base rounded in shape.

Abstract: An apparatus including rigid plate having a first face and a second face, a plurality of through seats arranged as a circular crown about an axis of symmetry (A), perpendicular to each seat and shaped as a circular crown segment; a plurality of knives carried by the plate, each being axially slidingly guided into a seat, independently of the other knives; each knife has a head which protrudes from the seat from the side of the first face, a prismatic body having an axial length greater than the seat, and a wedge-shaped end, opposite to the head, which protrudes from the second face when the head substantially abuts against the first face; the wedge-shaped ends circumferentially having a first profile, complementary to that of the frontal toothing to be obtained, and the knives can be replaced totally or partially with others having a second profile different from the first profile.
