Wheel hub unit
First Claim
1. A wheel hub unit comprising:
- a wheel hub (11) with a through-aperture (13) having internal splines (14);
a wheel bearing (19);
an outer joint part (15) of a constant velocity universal joint which, at the hub end, comprises a shaft journal (16) with shaft splines (17), which shaft journal (16) is inserted into the through-aperture (13) of the wheel hub;
an axial securing mechanism between the wheel hub (11) and the outer joint part (15) comprising a securing ring (18) having a rectangular cross-section and which engages corresponding rectangular circumferential grooves (31, 32) in the internal splines (14) and in the shaft splines (17), wherein the securing ring (18) is arranged near the end of the shaft journal, and wherein, the shaft journal (16), near its base, includes a centering collar (34) which, in a radially play-free way, engages the through-aperture (13) of the wheel hub (11) and wherein, at its end face, the shaft journal (16) comprises a central recess (28) which extends axially from the free end and project beyond the circumferential groove (32) in the internal splines (14), and a radial notch (29) which extends axially from the free end as far as the circumferential groove (32) in the internal splines (14) and into the central recess (28), and wherein inwardly bent free ends (35, 36) of the securing ring (18) extend through the notch (29) into the recess (28).
