Abstract
(EN) A case 71 is partitioned by a partition wall 93 into a first gear housing space 91 that houses a gear train 75 (a pump shaft gear 72, an idle gear 73, and a pump gear 74) which rotates at a relatively high speed and a second gear housing space 92 that houses a gear train 87 (a motor output gear 81, a first idle gear 82, a second idle gear 83, a third idle gear 84, a fourth idle gear 85, and an axle gear 86) which rotates at a relatively low speed.
(FR) Selon l’invention, un carter (71) est divisé par une paroi de séparation (93) en un premier espace de logement d'engrenages (91) qui loge un train d'engrenages (75) (un engrenage d'arbre de pompe (72), un pignon fou (73), et un engrenage de pompe (74)) qui tourne à une vitesse relativement élevée et un second espace de logement d'engrenages (92) qui renferme un train d'engrenages (87) (un engrenage de sortie de moteur (81), un premier pignon fou (82), un deuxième pignon fou (83), un troisième pignon fou (84), un quatrième pignon fou (85), et un engrenage d'essieu (86)) qui tourne à une vitesse relativement basse.
(JA) ケース71内において、仕切壁93により、相対的に高速で回転するギヤ列75(ポンプ軸ギヤ72、アイドルギヤ73およびポンプギヤ74)が収容される第1ギヤ収容空間91と相対的に低速で回転するギヤ列87(モータ出力ギヤ81、第1アイドルギヤ82、第2アイドルギヤ83、第3アイドルギヤ84、第4アイドルギヤ85および車軸ギヤ86)が収容される第2ギヤ収容空間92とが仕切られている。
