To provide a vehicle power device capable of suppressing temperature rise of a bearing part and simplifying a structure; and a wheel bearing with a generator.SOLUTION: A vehicle power device 1 comprises an outer ring rotation type wheel bearing 2, and a traveling motor 3 with a power generating function having a stator 18 mounted on an inner ring 5 and a rotor 19 mounted on an outer ring 4. The wheel bearing 2 and the traveling motor 3 with the power generating function have smaller diameters than an outer peripheral part on a brake rotor, and the traveling motor 3 with the power generating function is located in an axial direction range between a wheel mounting flange 7 and an out-board side surface 8a of a knuckle 8. The vehicle power device comprises a bracket 24 interposed between the knuckle 8 and the inner ring 5. The vehicle power device comprises both a cooling passage 39 disposed on a contact surface of the bracket 24 and the knuckle 8 facing each other, and inner ring cooling means 26 cooling the inside of the inner ring 5.SELECTED DRAWING: Figure 8A

    【課題】軸受部の温度上昇を抑制し、構造を簡単化することができる車両用動力装置および発電機付き車輪用軸受を提供する。【解決手段】車両用動力装置1は、外輪回転型の車輪用軸受2と、内輪5に取付けられたステータ18および外輪4に取付けられたロータ19を有する発電機能付き走行用モータ3とを備える。車輪用軸受2および発電機能付き走行用モータ3が、ブレーキロータにおける外周部よりも小径であり、且つ、発電機能付き走行用モータ3が、車輪取付フランジ7とナックル8のアウトボード側面8aとの間の軸方向範囲に位置する。ナックル8と内輪5との間に介在するブラケット24を備える。互いに対向するブラケット24とナックル8との当接面に設けられる冷却流路39、および内輪5の内部を冷却する内輪冷却手段26の両方を備えた。【選択図】図8A
