To provide a hub unit with a steering function which achieves improvement of material yield in manufacturing of an outer ring having a steering shaft and a bearing ring of a hub bearing, and workability and processing accuracy during processing.SOLUTION: A hub unit 1 with a steering function includes: a hub bearing 8 which rotationally supports a wheel 10; an outer ring 22 which is provided on an outer peripheral surface of an outer ring 12 of the hub bearing 8; a cylindrical steering shaft part 24 which extends upward and downward from an outer surface of the outer ring 22; a steering actuator 4 which rotates the hub bearing 8 around an axis AX of the steering shaft part 24; a unit support member 6 which supports the hub bearing 8 at a vehicle body through a rotary support member 26 in a manner that the hub bearing 8 can rotate around the axis AX of the steering shaft part 24; and an arm part 28 which protrudes to a vehicle rear from the outer ring 22 and to which the steering actuator 4 is connected. The arm part 28 is formed by a member different from that of the outer ring 22, and the arm part 28 and the outer ring 22 are connected.SELECTED DRAWING: Figure 1
【課題】転舵軸やハブベアリングの軌道輪を有するアウターリングの製造時における材料歩留まり、加工時の作業性および加工精度の向上を図ることができる操舵機能付ハブユニットを提供する。【解決手段】操舵機能付ハブユニット1は、車輪10を回転支持するハブベアリング8と、ハブベアリング8の外輪12の外周面に設けられたアウターリング22と、アウターリング22の外面から上方および下方に延びる筒状の転舵軸部24と、転舵軸部24の軸心AX回りにハブベアリング8を回転させる操舵用アクチュエータ4と、回転支持部材26を介して転舵軸部24の軸心AX回りに回転自在にハブベアリング8を車体に対して支持するユニット支持部材6と、アウターリング22から車両後方に突出し、操舵用アクチュエータ4が連結されるアーム部28とを備えている。アーム部28はアウターリング22と別部材で構成され、アーム部28とアウターリング22が結合されている。【選択図】図1
