本发明涉及一种电驱动单元,尤其作为混动模块或混动变速器的组成部分,一种用于机动车、尤其用于混动机动车的混动模块,和一种用于机动车的驱动装置。电驱动单元(1)包括驱动轴(3)以及第一电旋转机器(50),其中驱动轴(3)具有流体入口(20)以及具有与其耦联的至少一个第一径向出口(21)和至少一个端侧出口(24),其中通过第一径向出口(21)可以将流体输送给第一电旋转机器(50),并且其中根据本发明提出,中央流动通道(10)具有横截面扩宽,使得处于中央流动通道(10)中的流体在端侧出口(24)的区域中由于距驱动轴(3)的旋转轴线(4)的增大的间距而承受提高的离心力。借助根据本发明的电驱动单元以及配设有其的混动模块和包括混动模块的驱动装置,能够成本适宜地确保最佳的冷却和/或润滑流体运输。
The invention relates to an electric drive unit, in particular as part of a hybrid module or a hybrid transmission, to a hybrid module for a motor vehicle, in particular for a hybrid motor vehicle, and to a drive assembly for a motor vehicle. An electric drive unit (1) comprises a driveshaft (3) and a first electric rotation machine (50), wherein the driveshaft (3) has a fluid inlet (20) and at least one first radial outlet (21) and at least one end-face outlet (24) coupled to the fluid inlet, and fluid can be supplied to the first electric rotation machine (50) through the first radial outlet (21). According to the invention, the central flow channel (10) has a cross-section expansion such that fluid located in the central flow channel (10) in the region of the end-face outlet (24) is subjected to a higher centrifugal force on the basis of the increased distance to the rotational axis (4) of the drive shaft (3). By using the electric drive unit according to the invention, the hybrid module equipped therewith, and a drive assembly comprising the hybrid module, an optimal transport of cooling and/or lubricating fluid can be ensured in an inexpensive manner.
