Abstract:
(EN) Provided is a vehicular power device that is capable of, by allowing the heat of an electric motor installed within a brake rotor to be released efficiently, preventing malfunction, etc., of the electric motor and preventing deterioration of brake performance, preventing degradation of a lubricant within a bearing, and preventing deterioration of strength of a bearing material. This vehicular power device (1) is provided with: a wheel bearing (2); and an electric motor (3) that has a stator mounted to an outer ring (4) and a motor rotor (19) mounted to an inner ring (5). The electric motor (3) overall is smaller in diameter than an outer peripheral part on which a brake caliper is pressed in a brake rotor (12), and the entirety of the electric motor (3), except for a mounting part to be attached to a hub flange (7), is positioned in a range between the hub flange (7) and an inboard-side vehicle-body mounting surface (4a) of the wheel bearing (2). The outer peripheral surface of the electric motor (3) is provided with a relief part (22) for cooling the electric motor (3).
(FR) L'invention concerne un dispositif d'alimentation de véhicule qui est capable, en permettant à la chaleur d'un moteur électrique installé à l'intérieur d'un rotor de frein d'être libérée efficacement, d'empêcher un mauvais fonctionnement, etc, du moteur électrique et d'empêcher la détérioration des performances du frein, d'empêcher la dégradation d'un lubrifiant à l'intérieur d'un roulement, et d'empêcher la détérioration de la résistance d'un matériau de roulement. Ce dispositif de puissance de véhicule (1) comprend : un roulement de roue (2) ; et un moteur électrique (3) qui a un stator monté sur un anneau externe (4) et un rotor de moteur (19) monté sur un anneau interne (5). Le moteur électrique (3) est globalement plus petit en diamètre qu'une partie périphérique externe sur laquelle un étrier de frein est pressé dans un rotor de frein (12), et la totalité du moteur électrique (3), à l'exception d'une partie de montage destinée à être fixée à une bride de moyeu (7), est positionnée dans une plage entre la bride de moyeu (7) et une surface de montage de carrosserie de véhicule côté intérieur (4a) du roulement de roue (2). La surface périphérique externe du moteur électrique (3) est pourvue d'une partie en relief (22) pour refroidir le moteur électrique (3).
(JA) ブレーキロータ内に構成された電動機の熱を効率的に放出することで、電動機の異常等を防ぐと共に、ブレーキ性能の低下、軸受内の潤滑剤の劣化、および軸受材料の強度低下を防ぐことができる車両用動力装置を提供する。この車両用動力装置(1)は、車輪用軸受(2)と、外輪(4)に取付けられたステータおよび内輪(5)に取付けられたモータロータ(19)を有する電動機(3)とを備える。電動機(3)の全体が、ブレーキロータ(12)における、ブレーキキャリパが押し付けられる部分となる外周部よりも小径であり、且つ、電動機(3)におけるハブフランジ(7)への取付部を除く全体が、軸方向において、車輪用軸受(2)のインボード側の車体取り付け面(4a)からハブフランジ(7)までの範囲内に位置する。電動機(3)の外周面に、電動機(3)を冷却するための凹凸部(22)を備える。
