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 assembly (1, 16) for a motor vehicle. The hybrid drive assembly comprises a rotor (3), a stator (4), housings (5, 17), and a shaft, wherein the rotor (3), the stator (4) and the shaft are concentrically arranged, the housing (5, 17) comprise casing regions (7, 19) and side walls (8, 22) and a shaft holder (9), the shaft has penetrated or can penetrate through the shaft holder (9), the housing (5, 17) at least comprises coolant lines (10, 20) for cooling the stator (4). The high assemble cost of the hybrid drive assembly (1,16) is prevented by the following ways: the housings (5, 17) comprise the shaft and rotor brackets (11,23), wherein the shaft and the rotor brackets (11,23) form the shaft holder (9), and the rotor (3) can be operably supported on the outer sides of the shaft and the rotor brackets (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...
