The invention relates to a drive device (1) for a motor vehicle, comprising an electric machine (2) having a stator (2a) and a rotor (2b) and a rotor shaft (2c), a transmission (3), a housing (4) forming an engine compartment (5) and a transmission compartment (6) in which an oil pan (7) is arranged, oil can be conducted from the oil pan (7) into the region of the rotor (2b) by means of an oil supply system and from the rotor (2b) back into the oil pan (7) by means of an oil discharge system, a cooling water jacket (9) being formed in the region of the outer circumferential wall (8) of the engine compartment (5), the electric machine (2) being arranged so as to lie flat above the oil surface (7a) of the oil pan (7). A thermal coupling between the returned oil and the cooling water jacket (9) is at least partially effected when the oil is returned from the electric machine (2) to the oil pan (7) via an oil discharge system, the oil discharge system having a receiving space (18), this is achieved by a housing recess (19) which at least partially accommodates the oil during backflow and by a separating element (20) which is arranged separately in and/or above the housing recess (19) and which blocks the backflow oil.

    本发明涉及一种用于机动车的驱动装置(1),其具有电机(2),传动装置(3),壳体(4),壳体(4)构成发动机室(5)和传动装置室(6),电机(2)具有定子(2a)和转子(2b)以及转子轴(2c),在传动装置室(6)中设置油底壳(7),油能够通过供油系统从油底壳(7)引导到转子(2b)的区域中并且通过排油系统从转子(2b)引导回到油底壳(7)中,在所述发动机室(5)的外周壁(8)的区域中形成冷却水套(9),电机(2)布置为平放在所述油底壳(7)的油面(7a)上方。在油从电机(2)经由排油系统回流至所述油底壳(7)时、而至少部分地实现回流的油与冷却水套(9)之间的热耦合,排油系统具有容纳空间(18),其通过在回流时至少部分地容纳油的壳体凹槽(19)和单独布置在壳体凹槽(19)之中和/或之上的、阻挡回流的油的分隔元件(20)实现。
