To provide a hub unit with a rotating shaft, a steering system and a vehicle, capable of achieving improved reliability and assemblability.SOLUTION: A hub unit Br with a rotating shaft includes: a hub unit body 2 with a hub bearing 15 supporting the rotation of a wheel 9; and a unit supporting member 3 installed at a knuckle and supporting the hub unit body 2 to be rotatable around a rotating shaft center A extending in a vertical direction. The hub unit body 2 has rotating shaft parts 16b, 16c each of which protrudes vertically from the outer periphery of an annular part 16a installed at an outer ring 19 of a hub bearing 15, and the upper and lower rotating shaft parts 16b, 16c are supported to be rotatable around the rotating shaft center A at the unit supporting member 3 through rotation supporting members 4, 4. The rotation supporting member 4 has a stationary side bearing 38 installed at the upper rotating shaft part 16b and the stationary side bearing 38 receives radial loads in both directions acting on the hub bearing 15.SELECTED DRAWING: Figure 5
【課題】信頼性および組立性の向上を図ることができる転舵軸付ハブユニット、操舵システムおよび車両を提供する。【解決手段】転舵軸付ハブユニットBrは、車輪9を回転支持するハブベアリング15を有するハブユニット本体2と、ナックルに設けられハブユニット本体2を上下方向に延びる転舵軸心A回りに回転自在に支持するユニット支持部材3とを備える。ハブユニット本体2は、ハブベアリング15の外輪19に設けられた円環部16aの外周から上下にそれぞれ突出する転舵軸部16b,16cを有し、上下の転舵軸部16b,16cが回転支持部材4,4を介してユニット支持部材3に転舵軸心A回りに回転自在に支持される。回転支持部材4は、上側の転舵軸部16bに設けられた固定側軸受38を有し、固定側軸受38はハブベアリング15に作用するラジアル方向の両方向の荷重を受ける。【選択図】図5
