Abstract

A wheel hub/constant velocity joint unit wherein a wheel hub (60, 90) with a through-aperture (59, 89) carrying inner shaft teeth (44, 74) is clamped to an outer joint part (46, 76) of a constant velocity fixed joint (42, 72), which outer joint part (46, 76) comprises a formed-on journal (53, 83) with outer shaft teeth (54, 84), wherein the inner shaft teeth (44, 74) of the through-aperture (59, 89) and the outer shaft teeth (54, 84) of the journal (53, 83) engage one another and wherein a double-row wheel bearing (43, 73) is slid on to the wheel hub (60, 90) which comprises an inner bearing race (64, 94) which directly supports an end face (52, 82) of the outer joint part (46, 76), wherein half the sum of the pitch circle diameter of the joint balls PCD and the bearing width BL is greater than the center-to-center distance AGL between the constant velocity universal joint (42, 72) and the wheel bearing (43, 73).
