Title (EN) TWO MOTOR VEHICLE-DRIVING APPARATUS
(FR) APPAREIL D'ENTRAÎNEMENT DE VÉHICULE À DEUX MOTEURS
(JA) 2モータ車両駆動装置
Abstract:
(EN) The present invention addresses the problem of supplying lubricating oil to the gears of reduction gears in a two motor vehicle-driving apparatus equipped with parking lock mechanisms. The reduction gears comprise: an input gear shaft (23) with an input gear (23a); an output gear shaft (25) with an output gear (25a); and an intermediate gear shaft (24) that is provided between the input gear shaft (23) and the output gear shaft (25) and has a large diameter gear (24a) that meshes with the input gear (23a) and a small diameter gear (24b) that meshes with the output gear (25a). The parking lock mechanisms (40) comprise a parking gear (41) provided on the input gear shaft (23) on an extension line of the small diameter gear (24b) of the intermediate gear shaft (24) in the radial direction, and a parking pawl (42) with a hook that can engage with and disengage from the parking gear (41). The parking gear (41) is formed so that the outer diameter is larger than the outer diameter of the input gear (23a), and a portion of the parking gear (41) is immersed in lubricating oil that is sealed in the reduction gear casing (20).
(FR) La présente invention vise à fournir de l'huile de lubrification aux engrenages d'engrenages de réduction dans un appareil d'entraînement de véhicule à deux moteurs comportant des mécanismes de verrouillage de stationnement. À cet effet, selon l'invention, les engrenages de réduction comprennent : un arbre d'engrenage d'entrée (23) muni d'un engrenage d'entrée (23a) ; un arbre d'engrenage de sortie (25) muni d'un engrenage de sortie (25a) ; et un arbre d'engrenages intermédiaire (24) qui est disposé entre l'arbre d'engrenage d'entrée (23) et l'arbre d'engrenage de sortie (25) et qui a un engrenage de grand diamètre (24a) qui s'engrène avec l'engrenage d'entrée (23a) et un engrenage de petit diamètre (24b) qui s'engrène avec l'engrenage de sortie (25a). Les mécanismes de verrouillage de stationnement (40) comprennent un engrenage de stationnement (41) disposé sur l'arbre d'engrenage d'entrée (23) sur une ligne d'extension de l'engrenage de petit diamètre (24b) de l'arbre d'engrenages intermédiaire (24) dans la direction radiale, et un cliquet de stationnement (42) muni d'un crochet qui peut s'engrener avec l'engrenage de stationnement (41) et se désaccoupler de ce dernier. L'engrenage de stationnement (41) est formé de telle sorte que le diamètre externe est supérieur au diamètre externe de l'engrenage d'entrée (23a), et une partie de l'engrenage de stationnement (41) est immergée dans de l'huile de lubrification qui est scellée dans le carter d'engrenages de réduction (20).
(JA) パーキングロック機構を備えた2モータ車両駆動装置において、減速機の歯車に潤滑油を供給することを課題とする。減速機は、入力歯車(23a)を有する入力歯車軸(23)と、出力歯車(25a)を有する出力歯車軸(25)と、入力歯車軸(23)と出力歯車軸(25)との間に設けられ出力歯車(23a)と噛み合う大径歯車(24a)と出力歯車(25a)と噛み合う小径歯車(24b)を有する中間歯車軸(24)と、からなり、パーキングロック機構(40)は、中間歯車軸(24)の小径歯車(24b)の径方向の延長線上の入力歯車軸(23)に設けられるパーキングギヤ(41)と、パーキングギヤ(41)に係脱可能な爪部を有するパーキングポール(42)とを有し、パーキングギヤ(41)の外径は、入力歯車(23a)の外径より大きく形成し、パーキングギヤ(41)の一部が減速機ケーシング(20)に封入した潤滑油に浸かるようにした。
