WHEEL HUB JOINT UNIT

摘要

A wheel hub synchronous rotating joint unit, wherein a wheel hub (60, 90) provided with a through-opening (59, 89), which includes inner corrugated toothing (44, 74), is tensed with the external joint part (46, 76) of a synchronous rotating joint (42, 72), upon which a journal (53, 83) having outer corrugated toothing (54, 84) is formed, wherein the inner corrugated toothing (44, 74) of the through-opening (59, 89) and the outer corrugated toothing (54, 84) of the journal (53, 83) engage with each, and a two-row wheel bearing (43, 73) is placed onto the wheel hub (60, 90), comprising an inner bearing ring (64, 94) upon which a front surface (52, 82) of the external joint part (46, 76) rests directly, wherein half of the sum of the reference diameter of the balls of the joint PCD and the width of the bearing B_L is greater than the center distance A_GL between the synchronous rotating joint (42, 72) and wheel bearing (43, 73), i. e. (PCD + B_L) /2 > A_GL.
