To provide a hub unit with an auxiliary steering function which makes it possible to perform auxiliary steering according to a traveling state independently for each of left and right wheels, thereby improving the maneuverability of a vehicle and making it possible to improve stability/safety in traveling and improve fuel economy, and which makes it possible to easily machine and inexpensively manufacture an outer ring in a hub bearing; and to provide a vehicle comprising the same.SOLUTION: A hub unit with an auxiliary steering function comprises: a hub bearing 3 in which a wheel is mounted to an inner ring 12; and an outer ring support member which supports an outer ring 11 at each of two upper and lower positions via a rotation allowing support component in such a manner as to allow its free rotation around a vertically extending auxiliary steering shaft center A. The outer ring 11 comprises: a cylindrical outer ring body 61 in which a raceway groove 11a for a rolling element is formed on its inner periphery; and an auxiliary steering member 62 which is located on the outer peripheral side of the outer ring body 61 and is provided with supported parts 19A and 19B each supported by the rotation allowing support component so as to be freely rotatable around the auxiliary steering shaft center A. The outer ring body 61 and the auxiliary steering member 62 are separate components and are joined to each other.SELECTED DRAWING: Figure 8
【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、またハブベアリングの外輪の加工が容易でかつ安価に製作することができる補助転舵機能付ハブユニットおよびそれを備えた車両を提供する。【解決手段】内輪12に車輪が取り付けられるハブベアリング3と、外輪11を上下方向に延びる補助転舵軸心A回りに回転自在なように上下2箇所でそれぞれ回転許容支持部品を介して支持する外輪支持部材とを備える。外輪11は、内周に転動体の軌道溝11aが形成された円筒状の外輪本体61と、この外輪本体61の外周側にあって回転許容支持部品に補助転舵軸心A回りに回転自在に支持される被支持部19A,19Bが設けられた補助転舵部材62とを有する。外輪本体61と補助転舵部材62は別部品であって互いに結合されている。【選択図】図8
