Title (EN) RAILROAD VEHICLE DRIVE UNIT
(FR) UNITÉ D'ENTRAÎNEMENT DE VÉHICULE FERROVIAIRE
(JA) 鉄道車両駆動ユニット
Abstract:
(EN) A railroad vehicle drive unit (12) is provided with a reduction gear housing (13), an input-side rotating member (14), a reduction gear mechanism (15), fixation members (24, 25) which are arranged within the reduction gear housing (13) and are connected and fixed to a vehicle body, and a lubricating oil circulating mechanism which circulates in the drive unit a lubricating oil.  The lubricating oil circulating mechanism is provided with an axis oil path (14a) which extends within the input-side rotating member (14) in the axis direction, lubricating oil supply openings (14b-14e) which extend from the axis oil path (14a) to the outer-diameter surface of the input-side rotating member (14), a lubricating oil discharge opening (25c) which is provided in the fixation member (25), and a circulation oil path (34) which connects the lubricating oil discharge opening (25c) and the axis oil path (14a) and recirculates the lubricating oil, which has been discharged from the lubricating oil discharge opening (25c), to the axis oil path (14a).
(FR) L'invention porte sur une unité d'entraînement de véhicule ferroviaire (12) comportant un boîtier d'engrenage réducteur (13), un élément rotatif côté entrée (14), un mécanisme d'engrenage réducteur (15), des éléments de fixation (24, 25) disposés à l'intérieur du boîtier d'engrenage réducteur (13) et reliés et fixés à un corps de véhicule, et un mécanisme de circulation d'huile lubrifiante circulant dans l'unité d'entraînement d'une huile lubrifiante. Le mécanisme de circulation d'huile lubrifiante comporte une circulation d'huile axiale (14a) à l'intérieur de l'élément rotatif côté entrée (14) en direction axiale, une ouverture d'alimentation en huile lubrifiante (14b-14e) de la circulation d'huile axiale (14a) à la surface de diamètre extérieur de l'élément rotatif côté entrée (14), une ouverture de décharge d'huile lubrifiante (25c) disposée dans l'élément de fixation (25), et une circulation d'huile (34) reliant l'ouverture de décharge d'huile lubrifiante (25c) et la circulation d'huile axiale (14a) et faisant recirculer l'huile lubrifiante déchargée de l'ouverture de décharge d'huile lubrifiante (25c) à la circulation d'huile axiale (14a).
(JA)  鉄道車両駆動ユニット12は、減速機ハウジング13と、入力側回転部材14と、減速機構15と、減速機ハウジング13の内部に配置され、車両本体に連結固定される固定部材24,25と、駆動ユニット内で潤滑油を潤滑させる潤滑油循環機構とを備える。そして、潤滑油循環機構は、入力側回転部材14の内部を軸方向に延びる軸心油路14aと、軸心油路14aから入力側回転部材14の外径面に向かって延びる潤滑油供給口14b~14eと、固定部材25に設けられた潤滑油排出口25cと、潤滑油排出口25cおよび軸心油路14aを接続し、潤滑油排出口25cから排出された潤滑油を軸心油路14aに還流する循環油路34とを含む。
