Title (EN) IN-WHEEL MOTOR DRIVE DEVICE AND SPEED REDUCTION DEVICE 
(FR) DISPOSITIF D'ENTRAÎNEMENT DE MOTEUR-ROUE ET DISPOSITIF DE RÉDUCTION DE VITESSE 
(JA) インホイールモータ駆動装置および減速装置
Abstract:
(EN) A motor part (21) of an in-wheel motor drive device (1) includes a motor housing (2) that rotationally supports a motor shaft (22) with two or more bearings (27, 28). A speed reduction part (31) includes a plurality of speed reducer elements (32s, 34, 15) that rotate around an axis, said axis being parallel to the motor shaft (22), and includes a speed reducer housing (3) that rotationally supports each speed reducer element with two or more bearings (32m, 32n, 34m, 34n, 36m, 36n). The motor housing (2) and the speed reducer housing (3) have, in mutually facing sections thereof, fastening parts that link and fix the two in a separable manner, and receding/protruding fitting parts (601, 603) for positioning.
(FR) La présente invention concerne une partie moteur (21) d'un dispositif d'entraînement de moteur-roue (1) comprenant un carter de moteur (2), lequel porte en rotation un arbre de moteur (22) au moyen de deux paliers ou plus (27, 28). Une partie de réduction de vitesse (31) comprend une pluralité d'éléments de réduction de vitesse (32s, 34, 15), lesquels tournent autour d'un axe, ledit axe étant parallèle à l'arbre de moteur (22). ladite partie de réduction de vitesse comprend également un logement de réducteur de vitesse (3), lequel porte en rotation chaque élément réducteur de vitesse au moyen de deux paliers ou plus (32m, 32n, 34n, 36m, 36n). Le carter de moteur (2) et le logement de réducteur de vitesse (3) comportent, dans leurs sections mutuellement opposées, des parties de fixation, lesquelles relient et fixent le carter et le logement de manière séparable et lesquelles mettent en retrait/en saillie des parties d'ajustement (601, 603) pour le positionnement.
(JA) インホイールモータ駆動装置(1)のモータ部(21)は、2個以上の軸受(27,28)でモータ軸(22)を回転支持するモータハウジング(2)を含み、減速部(31)は、モータ軸(22)と平行な軸線の周りで回転する複数の減速機要素(32s,34,15)と、2個以上の軸受(32m,32n,34m,34n,36m,36n)で各減速機要素を回転支持する減速機ハウジング(3)とを含む。モータハウジング(2)および減速機ハウジング(3)は、互いに向き合う部分に、両者を分離可能に連結固定する締結部と、位置決めのための凹凸嵌合部(601,603)とを有している。
