  • Publication number: 20250010657
    Abstract: A hub-bearing unit includes a stationary radially outer ring and a rotatable hub having an axially extending tubular portion at an axially inner side and a radially outwardly extending toothed profile. A portion of the hub is located radially inside the radially outer ring. A radially inner ring is mounted on the hub, and a toothed sleeve is mounted axially inward of the radially inner ring and has a radially inner surface including at least one groove mating with the toothed profile. The tubular portion includes a radially outer cylindrical surface, an axial portion of the radially inner surface of the toothed sleeve lies on or is bounded by a first imaginary cylinder, the axial portion of the radially inner surface engages the radially outer cylindrical surface, and the first imaginary cylinder and the radially outer cylindrical surface are coaxial.

  • Publication number: 20240383277
    Abstract: A hub-bearing assembly having an axis of rotation includes a stationary radially outer ring and a flanged hub radially inside the radially outer ring and rotary about the axis and about the radially outer ring. The flanged hub has a toothed profile and an axially inner tubular portion. A radially inner ring is mounted in axial abutment on the flanged hub. A toothed sleeve is mounted axially close to the radially inner ring and angularly coupled to the toothed profile of the flanged hub. The flanged hub has a profile gradually transitioning between a radially outer surface of the toothed profile and a radially outer cylindrical surface of the tubular portion of the flanged hub.

  • Patent number: 12134120
    Abstract: A method and tool for obtaining face teeth having a plurality of radial teeth on an annular collar of an inner ring of a wheel hub; in which annular roughed-out face teeth are first formed on the collar coaxial with an axis of symmetry (A) of the collar and having a plurality of radial first teeth arranged in a crown and alternating at constant pitch with a plurality of radial first concavities; then a shaping tool comprising a pressing head provided with annular calibration face teeth is axially pressed onto the collar to engage with the annular roughed-out face teeth, second radial concavities of the annular calibration teeth each being delimited by a bottom wall having a rounded circumferential profile exactly reproducing in negative the rounded circumferential profile of the tips or ridges of the radial teeth of the required face teeth.

  • Publication number: 20240359504
    Abstract: A hub-bearing assembly includes a stationary radially outer ring, a flanged hub extending into an interior of the radially outer ring and configured to rotate relative to the radially outer ring, and a radially inner ring mounted on the flanged hub and axially abutting a portion of the flanged hub. A toothed sleeve is mounted to the hub axially inward of and adjacent to the radially inner ring and is rotationally fixed relative to the flanged hub. An auxiliary ring is mounted on the flanged hub in contact with the toothed sleeve. The flanged hub includes an axially inner rolled edge in contact with the auxiliary ring and configured to maintain a preload on the radially inner ring, and the auxiliary ring is configured to accommodate deformations induced by the formation of the rolled edge.

  • Patent number: 11806943
    Abstract: An apparatus including a plurality of first and second pressing elements arranged in crown symmetrically around an axis of symmetry (B) so that a first end of a first pressing element cooperates in contact with a second end of a second pressing element; wherein the first and second pressing elements are supported slidingly and passing through by, respectively, a first and a second plate coupled and bound to each other, in respective second and first slits angularly spaced apart; the first pressing elements being provided with hammerheads circumferentially wider than the second slits and which cooperate circumferentially without play in contact with each other, and the second pressing elements being provided with engraving heads circumferentially wider than the first slits, which cooperate circumferentially without play in contact with each other.
