A method and equipment for forming a front toothing having a plurality of radial teeth on an annular collar of an inner ring of a wheel hub, wherein a plurality of first knives are axially and sequentially impressed on the annular collar and have a first predetermined circumferential profile (P) configured to form radial reliefs which are spaced by imprints and have a rounded circumferential profile corresponding to the profile of the ridges of the radial teeth to be obtained; thereafter, a plurality of second knives are axially and sequentially impressed on the annular collar inside the imprints and have a third predetermined circumferential profile (P) configured to reproduce in reverse at least part of respective opposite flanks of the radial teeth of the front toothing to be obtained.

Front toothing on an inner ring of a wheel hub and associated equipment

A hub bearing assembly includes a hub of light metallic material forming a cylindrical portion, on which an inner tubular ring having a raceway is mounted; on the first inner tubular ring a second inner ring having a second raceway is fastened; formed between the cylindrical portion of the hub and the inner tubular ring is a cylindrical interstice containing a brazing bonding material or a structural adhesive which integrally binds the hub to the first inner tubular ring.
