To provide a hub unit with a steering function, a steering system and a vehicle, capable of achieving cost reduction by reducing energy loss and the number of components of a system and capable of preventing deterioration of riding comfort by suppressing an increase in unspring weight.SOLUTION: A hub unit 1 includes: a hub unit body 2 with a hub bearing 15 supporting the rotation of a wheel 9; and a unit support member 3 provided on an underbody frame component of a suspension device and supporting the hub unit body 2 to be rotated around a steering axial center A; and an a steering actuator 5 driving the rotation of the hub unit body 2 around the steering axial center A. The steering actuator 5 has a motor 26, and a conversion mechanism 25 including a conversion section 25c for converting a rotational motion of a motor rotary shaft 26a into a linear motion. The motor rotary shaft 26a and a rotary shaft of the conversion section 25c of the conversion mechanism 25 are arranged on the same linear line.SELECTED DRAWING: Figure 2
【課題】システムのエネルギー損失および部品点数を抑え、コストを低減しつつハブユニット全体を小型化することで、ばね下重量の増加を抑えて乗り心地の悪化を防ぐことができ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】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、懸架装置の足回りフレーム部品に設けられハブユニット本体2を転舵軸心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A心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、モータ回転軸26aの回転運動を直動運動に変換するための変換部25cを含む変換機構25とを有する。モータ回転軸26aと、変換機構25の変換部25cの回転軸とを同一直線上に配置した。【選択図】図2
