Problems solved by technology

Furthermore, machining leads to the risk of increased vibration values ​​( / oscillating values) of the flange relative to the brake disc, as well as problems with the inevitable presence of burrs on the surface of the outer chamfer
[0008] In addition, machining ultimately affects the production time of the bearing and increases the associated costs

Embodiment Construction

[0016] refer to figure 1 and figure 2 , reference numeral 10 generally designates a flanged hub for a wheel hub bearing 2, which comprises a flanged inner ring 1 and an outer ring 3, the outer ring 3 being coaxial with the axis A.

[0017] Throughout the description and claims, terms and expressions indicating position and direction, such as "radial" and "axial", are intended to refer to the central axis of rotation A of the bearing 2 . On the other hand, expressions such as "axially outer" and "axially inner" refer to the assembled state, preferably in this case to the wheel side and the side opposite ( / opposite) to the wheel side, respectively.

[0018] The flanged inner ring 1 has: a tubular support body 4 for the bearing 2, coaxial with the axis A; A plurality of threaded through holes 6 distributed.

[0019] According to known ( / prior art) technology (and therefore not shown in the previously mentioned figures), the sliding track for the bearing 2 is hollowed out dire...

Abstract

Provided is a flanged inner ring (1) for wheel hub bearings (2). The inner ring comprises a tubular body (4) supporting the bearing, the body (4) being coaxial with an axis (A), and a flange (5), which is transversal to the axis (A), the flange (5) being provided with a plurality of threaded through holes (6) that are distributed around the axis (A) and includes: an outer annular mounting surface(11) and an inner surface (12) that is axially faced towards an outer ring (3) of the bearing; the flange having a respective base axial thickness (SAF) and comprising for each threaded through hole,a respective radial arm (13) which is arranged on the inner surface (12) of the flange facing the outer ring; the inner ring being forged in one piece together with the flange and the radial arms. Between each pair of adjacent arms there is a flower-shaped sector (14) with a chamfer (15) made by forging along the outer surface thereof.

Description

technical field [0001] The present invention relates to a wheel hub with a flange, in particular to a flanged inner ring for a wheel hub bearing. Background technique [0002] Known flanged hubs for hub bearings have: a tubular support body for the hub bearing (in particular for its inner ring), which is coaxial with the axis of rotation of the bearing; and a flange, which is aligned with the axis of rotation Transversely, comprising a plurality of threaded through-holes evenly distributed about the axis, and having: [0003] - the outer annular mounting surface on which the brake disc and rim are mounted, secured using threaded screws inserted through holes, and [0004] - an inner surface, which axially faces the outer ring of the rolling bearing. [0005] The flange has a uniform basic axial thickness designed to withstand the typical mechanical stresses of hub bearings, and also has a radial arm for each threaded through hole, the radial arm is arranged on the side of ...
