Abstract:
(EN) One embodiment of the drive device of the present invention is equipped with a rotor, a stator, a housing having a storage section capable of storing oil, a pump unit driven by a motor shaft, and a cooling device attached to the housing on the bottom side thereof in the vertical direction. The cooling device has: an inflow port which is connected to the bottom-side region in the vertical direction of the interior of the storage section, and through which oil stored in the storage section flows into the cooling device; and a discharge port for discharging oil from the interior of the cooling device. The cooling device cools the oil flowing therethrough. The housing has an inner lid section for covering one side of the stator in the axial direction, an outer lid section attached to the inner lid section on the one side thereof in the axial direction, and an oil intake channel which connects the discharge port and the inflow port. The inner lid section and the outer lid section are separate members. The oil intake channel has a first section positioned between the inner lid section and the outer lid section, and an introduction section connecting the discharge port and the first section.
(FR) Selon un mode de réalisation, la présente invention concerne un dispositif d'entraînement comprenant un rotor, un stator, un carter ayant une section de stockage pouvant stocker de l'huile, une unité pompe menée par un arbre moteur, et un dispositif de refroidissement fixé au carter sur son côté inférieur dans la direction verticale. Le dispositif de refroidissement comprend : un orifice d'entrée qui est relié à la région côté inférieur dans la direction verticale de l'intérieur de la section de stockage, et par lequel l'huile stockée dans la section de stockage s'écoule dans le dispositif de refroidissement ; et un orifice de refoulement permettant de refouler l'huile de l'intérieur du dispositif de refroidissement. Le dispositif de refroidissement refroidit l'huile qui le traverse. Le carter possède une section de couvercle interne permettant de recouvrir un côté du stator dans la direction axiale, une section de couvercle externe fixée à la section de couvercle interne sur un côté dans la direction axiale, et un canal d'admission d'huile qui relie l'orifice de refoulement et l'orifice d'entrée. La section de couvercle interne et la section de couvercle externe sont des éléments séparés. Le canal d'admission d'huile comporte une première section positionnée entre la section de couvercle interne et la section de couvercle externe et comporte une section d'introduction reliant l'orifice de refoulement et la première section.
(JA) 本発明の駆動装置の一つの態様は、ロータと、ステータと、オイルを貯留可能な収容部を有するハウジングと、モータシャフトを介して駆動されるポンプ部と、ハウジングの鉛直方向下側に取り付けられる冷却装置と、を備える。冷却装置は、収容部の内部における鉛直方向下側領域と繋がり、収容部に貯留されたオイルを冷却装置の内部に流入させる流入口と、冷却装置の内部からオイルを流出させる流出口と、を有し、かつ、冷却装置の内部を流れるオイルを冷却する。ハウジングは、ステータの軸方向一方側を覆う内蓋部と、内蓋部の軸方向一方側に取り付けられる外蓋部と、流出口と吸入口とを繋ぐ吸入油路と、を有する。内蓋部と外蓋部とは、互いに別部材である。吸入油路は、内蓋部と外蓋部との間に配置される第1部分と、流出口と第1部分とを繋ぐ導入部分と、を有する。
