Hybrid drive for a motor vehicle
Abstract:
A hybrid drive for a motor vehicle which has a combustion engine, a transmission with a transmission input shaft which can be coupled with the combustion engine, and an electric machine which is positioned between the combustion engine and the transmission. The electric machine has a stator and a rotor which interacts with the transmission input shaft and is supported by a transmission housing input part. The transmission input shaft is supported, by a fixed radial bearing and a spaced radial bearing, in a bearing journal of the transmission housing input part. The rotor is connected, in a rotationally fixed manner, to an extension of the transmission input shaft which protrudes from a bearing journal. A radial shaft seal is positioned at the end of the bearing journal, facing the rotor, and the two radial bearings are cooled and lubricated by transmission oil.
