To provide a hub unit with a steering function which enables steering at a fine angle of a steering wheel or a non-steering wheel in addition to normal steering of the steering wheel to achieve improvement of fuel consumption, improvement of traveling stability etc. and compactification of a steering actuator, and to provide a steering system.SOLUTION: This hub unit with a steering function includes: a hub unit body 2 having a hub bearing 15 for supporting a wheel 9; a unit support member 3 which is provided at a knuckle 6 and supports the hub unit body 2 in a manner that the hub unit body 2 can rotate around a steering axis as seen in a vertical direction; and a steering actuator 5 which rotationally drives the hub unit body 2 around the steering axis. The steering actuator 5 has: a motor 26; a speed reducer 27 which reduces a speed of rotation of the motor 26; and a linear mechanism 25 which converts rotational output of the speed reducer 27 into linear motion. A gear is applied to the speed reducer 27.SELECTED DRAWING: Figure 2
【課題】操舵輪の通常の操舵に加えて、操舵輪または非操舵輪に微小な角度の操舵が行えて、燃費の改善および走行安定性の向上等が図れると共に、操舵用アクチュエータをコンパクトにすることができる操舵機能付ハブユニットおよび操舵システムを提供する。【解決手段】この操舵機能付ハブユニットは、車輪9を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6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の回転を減速する減速機27と、減速機27の回転出力を直進運動に変換する直動機構25とを有し、減速機27に歯車を適用した。【選択図】図2
