Abstract

A wheel hub-constant velocity joint unit in which a wheel hub (60, 90) with a passage opening (59, 89) that carries inner shaft teeth (44, 74) is tensioned with the outer joint part (46, 76) of a constant velocity joint (42, 72) on which a journal (53, 83) is formed with outer shaft teeth (54, 84), wherein inner shaft teeth (44, 74) of the passage opening (59, 89) and outer shaft teeth (54, 84) of the journal (53, 83) mesh in each other and a two-row wheel bearing (43, 73) is pushed onto the wheel hub (60, 90) that includes an inner bearing ring (64, 94) on which a front face (52, 82) of the outer joint part (46, 76) is supported directly, wherein the pitch circle diameter (TKD) of the roller bearing is greater than the pitch circle diameter (PCD) of the constant velocity joint.
