Title (EN) ELECTRIC OIL PUMP
(FR) POMPE À HUILE ÉLECTRIQUE
(ZH) 电子油泵
Abstract:
(EN) An electric oil pump (100) comprises a pump housing, a first rotor assembly (8), a pump shaft (5), a second rotor assembly (3), a stator assembly (4), and a circuit board assembly (6). The pump housing comprises at least a first housing (1), a second housing (2), and a third housing (7). A first cavity (80) is formed between the first housing (1) and the second housing (2). A second cavity (90) is formed between the second housing (2) and the third housing (7). The first rotor assembly (8) is accommodated in the first cavity (80). The second rotor assembly (3), the stator assembly (4), and the circuit board assembly (6) are accommodated in the second cavity (90). The first cavity (80) and the second cavity (90) are isolated by an isolation portion (22), such that working media provided therein do not communicate with each other.
(FR) La présente invention concerne une pompe à huile électrique (100) qui comprend un boîtier de pompe, un premier ensemble de rotor (8), un arbre de pompe (5), un deuxième ensemble de rotor (3), un ensemble de stator (4), et un ensemble de carte de circuit imprimé (6). Le boîtier de pompe comprend au moins un premier boîtier (1), un deuxième boîtier (2) et un troisième boîtier (7). Une première cavité (80) est formée entre le premier boîtier (1) et le deuxième boîtier (2). Une deuxième cavité (90) est formée entre le deuxième boîtier (2) et le troisième boîtier (7). Le premier ensemble de rotor (8) est logé dans la première cavité (80). Le deuxième ensemble de rotor (3), l’ensemble de stator (4) et l’ensemble de carte de circuit imprimé (6) sont logés dans la deuxième cavité (90). La première cavité (80) et la deuxième cavité (90) sont isolées par une partie d’isolation (22), de sorte que les milieux de travail disposés à l’intérieur de celles-ci ne communiquent pas entre elles.
(ZH) 一种电子油泵(100),包括泵壳体、第一转子组件(8)、泵轴(5)、第二转子组件(3)、定子组件(4)以及线路板组件(6),泵壳体至少包括第一壳体(1)、第二壳体(2)以及第三壳体(7),第一壳体(1)和第二壳体(2)之间形成第一内腔(80),第二壳体(2)和第三壳体(7)之间形成第二内腔(90),第一转子组件(8)容置于第一内腔(80),第二转子组件(3)、定子组件(4)以及线路板组件(6)容置于第二内腔(90),第一内腔(80)与第二内腔(90)通过隔部(22)隔离设置,两者的工作介质不连通。
