To provide a simple and firm hub unit with auxiliary steering function by which auxiliary steering depending a travel state can be performed for left and right wheels independently, maneuverability of a vehicle can be improved, and improvements in travel stability/safety and fuel consumption can be achieved, and a vehicle.SOLUTION: The hub unit comprises: a hub unit body 4 having a hub bearing 3; a unit support member 5 which is installed onto a vehicle body via a suspension device, and so supports the hub unit body 4 at vertical two points as to be rotatable around an auxiliary steering axis which extends in a vertical direction; and an auxiliary steering actuator 6 which is installed onto the unit support member 5 and rotates the hub unit body 4 around the auxiliary steering axis. The auxiliary steering actuator 6 includes a motor 27 and a direct-acting mechanism 29, and a direct-acting output part is connected to the hub unit body 4. The direct-acting mechanism 29 is configured from, for example, a feed screw mechanism having a self-locking function for a trapezoidal screw or the like.SELECTED DRAWING: Figure 2
【課題】走行状況に応じた補助的な転舵が左右輪独立で行えて、車両の運動性能を向上させ、走行の安定・安全性の向上と燃費の改善を図ることが可能となり、また簡素でかつ堅固な補助転舵機能付ハブユニットおよび車両を提供する。【解決手段】ハブベアリング3を有するハブユニット本体4と、車体に懸架装置を介して設置されてハブユニット本体4を上下方向に延びる補助転舵軸心回りに回転自在なように上下2箇所で支持するユニット支持部材5と、ユニット支持部材5に設置されてハブユニット本体4を補助転舵軸心回りに回転させる補助転舵用アクチュエータ6とを備える。補助転舵用アクチュエータ6が、モータ27と、直動機構29とで構成され、直動出力部がハブユニット本体4に連結される。直動機構29は、例えば台形ねじ等のセルフロック機能を備えた送りねじ機構とされる。【選択図】図2
