To provide a hub unit with a steering function which can inhibit increase of an unspringing weight to prevent deterioration of riding quality and prevent undesired change of an angle of a tire, and to provide a steering system and a vehicle.SOLUTION: A hub unit 1 with a steering function includes: a hub unit body 2 having a hub bearing 15 which rotatably supports a wheel 9; a unit support member 3 which is provided at an underbody frame component and supports the hub unit body 2 in such a manner that the hub unit body 2 may rotate around a steering axis A extending in a vertical direction; and a steering actuator 5 which drives the hub unit body 2 in such a manner that the hub unit body 2 rotates around the steering axis A. The steering actuator 5 has: a motor 26; and a straight motion mechanism 25 which converts rotational output of the motor 26 into straight motion of an output rod 25a. The output rod 25a is moved forward or rearward in a straight direction to drive the hub unit body 2 to rotate the hub unit body 2 around the steering axis A. The steering actuator 5 has straight motion position holding means 7 which holds a position of the output rod 25a.SELECTED DRAWING: Figure 2

    【課題】ばね下荷重の増加を抑えて乗り心地の悪化を防ぐと共に、タイヤの角度が不所望に変わることを防止し得る操舵機能付ハブユニット、操舵システムおよび車両を提供する。【解決手段】操舵機能付ハブユニット1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、足回りフレーム部品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、ハブユニット本体2を転舵軸心A回りに回転駆動させる操舵用アクチュエータ5とを備える。操舵用アクチュエータ5は、モータ26と、モータ26の回転出力を出力ロッド25aの直進運動に変換する直動機構25とを有し、出力ロッド25aが直進方向に進退することで、ハブユニット本体2が転舵軸心A回りに回転駆動される。操舵用アクチュエータ5は、出力ロッド25aの位置を保持する直動位置保持手段7を有する。【選択図】図2
