车辆用驱动装置
摘要：
本发明实现了一种车辆用驱动装置，能够将向摩擦部件供给的油量抑制成较少的量，并能高效地冷却摩擦部件以及旋转电机双方。车辆用驱动装置（D）具有：与内燃机（E）驱动连结的输入部件（I）；与车轮驱动连结的输出部件；选择性地将输入部件（I）与输出部件驱动连结的摩擦接合装置（CL）；以及设置于连结输入部件（I）和输出部件的动力传递路径上的旋转电机（MG）。车辆用驱动装置（D）具备：收纳油室（H2），在该收纳油室（H2）至少收纳摩擦接合装置（CL）的摩擦部件（27），并且其内部充满油；收纳旋转电机（MG）的收纳空间（S）；向收纳油室（H2）供给油的第一油路（L1）；将油从收纳油室（H2）排出的第二油路（L2）；以及将从第二油路（L2）排出的油朝收纳空间（S）供给的第三油路（L3）。
摘要（英）：

A drive device for a vehicle, configured so that both a friction member and a dynamo-electric machine can be efficiently cooled while the amount of supply of oil to the friction member is reduced. A drive device (D) for a vehicle comprises: an input member (I) connected in a driving manner to the internal combustion engine (E); an output member connected in a driving manner to wheels; a friction engagement device (CL) for selectively connecting the input member (I) and the output member in a driving manner; and a dynamo-electric machine (MG) provided in the power transmission path which connects the input member (I) and the output member. The drive device (D) for a vehicle also comprises: an oil containing chamber (H2) for at least containing the friction members (27) of the friction engagement device (CL) and filled with oil; a containing space (S) for containing the dynamo-electric machine (MG); a first oil path (L1) for supplying oil to the oil containing chamber (H2); a second oil path (L2) for discharging oil from the oil containing chamber (H2); and a third oil path (L3) for supplying the oil, which is discharged from the second oil path (L2), to the containing space (S).
