The invention relates to a coolant supply system for an electric vehicle axle power plant having an electric machine, in a motor housing (2) of which a stator (4) interacts with a rotor (5), the electric machine being transmitted to at least one wheel of the axle via a transmission (19). According to the invention, a coolant separator (57) is arranged in the motor housing (2), which coolant separator divides the interior of the motor housing (2) into a radially outer stator space (59), in which the stator (4) and the stator winding (21) thereof are arranged, and into a radially inner rotor space (61), which is separated from the radially outer stator space in a fluid-tight manner as much as possible, a rotor (5) is arranged in the radially inner rotor space.
本发明涉及一种电动车辆车桥动力设备的冷却剂供应系统,该电动车辆车桥动力设备具有电机,在电机的电机壳体(2)中,定子(4)与转子(5)共同作用,其中电机经由传动机构(19)传动到车桥的至少一个车轮。根据本发明,在电机壳体(2)中布置有冷却剂分离器(57),该冷却剂分离器将电机壳体(2)的内部空间划分为径向外部定子空间(59)以及与该径向外部定子空间尽可能液密地分开的、径向内部转子空间(61),在径向外部定子空间中布置有定子(4)及其定子绕组(21),在径向内部转子空间中布置有转子(5)。
