To provide a hub unit with a steering function which achieves simplification and compactification of a structure of a connection part between a steering actuator and a hub unit body and enables improvement of strength and durability of the connection part in a limited space, 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 which rotatably supports a wheel; a unit support member 3 which is provided at an underbody frame component of a suspension device 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 is supported so as to be swingable around a swing axis A1 extending in the vertical direction through a swing support member relative to the unit support member 3.SELECTED DRAWING: Figure 1
【課題】操舵用アクチュエータとハブユニット本体の連結部の構造を簡素かつコンパクト化し、限られた空間内での前記連結部の強度および耐久性を高める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】操舵機能付ハブユニット1は、車輪を回転支持するハブベアリング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、ユニット支持部材3に対して、上下方向に延びる揺動軸心A1回りに揺動支持部材を介して揺動自在に支持されている。【選択図】図1
