Embodiment Construction
[0013] exist figure 1 The hybrid drive 1 is clearly visible in . The hybrid drive 1 is part of a drive train of a motor vehicle. The hybrid drive 1 includes an electric machine 2 with a rotor 3 and a stator 4 . The rotor 3 and the stator 4 are arranged in a housing 5 . In addition, a shaft (not shown in the figure) is provided. In particular, the shaft can be driven by the internal combustion engine. The shaft can be designed as a clutch input shaft. The housing 5 is designed in particular as a clutch housing.
[0014] The housing 5 defines an oil chamber 6 . The oil chamber 6 is open from the transmission side and is filled accordingly. The rotor 3 and the stator 4 are arranged in an oil chamber 6 . The housing 5 has a housing region 7 and side walls 8 . The jacket region 7 extends substantially axially and circumferentially. The side walls 8 extend inwardly from the cover region 7 . Firstly, the side walls 8 extend substantially radially inwards from the housing r...

Abstract
The invention relates to a hybrid drive (1, 16) for a motor vehicle, which has a rotor (3), a stator (4), a housing (5, 17) and a shaft, wherein the rotor (3), the stator ( 4) Arranged concentrically with the shaft, wherein the housing (5, 17) has a housing region (7, 19) and side walls (8, 22) and a shaft receptacle (9), wherein the shaft has been The shaft receptacle (9) penetrates or can penetrate, wherein the housing (5, 17) at least partially has coolant lines (10, 20) for cooling the stator (4). The high assembly effort of the hybrid drive (1, 16) can be avoided in that the housing (5, 17) has a shaft- and a rotor carrier (11, 23), wherein, on the one hand, the shaft- and the rotor carrier ( 11, 23) form the shaft receptacle (9), and on the other hand the rotor (3) is operatively supported on the shaft and on the outer side of the rotor support (11, 23).
Description
technical field [0001] The invention relates to a hybrid drive for a motor vehicle having a rotor, a stator, a housing and a shaft, wherein the rotor, the stator and the shaft are arranged concentrically, wherein the housing has a housing region and side walls and the shaft Receptacle, wherein the shaft has penetrated or can pass through the shaft receptacle, wherein the housing has at least partially coolant ducts for cooling the stator. Background technique [0002] Various hybrid drives for motor vehicles are known in the prior art. In this case, the rotor and the stator can be arranged around a shaft, the shaft being driven by the internal combustion engine. The shaft can be used as a clutch input shaft or as a transmission input shaft. [0003] A hybrid drive for a motor vehicle is known from EP1551659B1. The device is provided with an internal combustion engine, two electric motors and a set of vehicle speed change devices with variable transmission ratios. The ele...
