Embodiment Construction

[0031] figure 1A first example of a drive unit 10 of a motor vehicle is shown, which has a transmission 12 , a transmission housing 14 and an electric motor unit 16 . The electric motor unit 16 has a stator 18 and a rotor 20 . The rotor 20 has a drive shaft 22 which passes through the rotor 20 and the electric motor unit 16 in the longitudinal direction. The drive shaft 22 is supported in bearings 24 . Arranged on the drive shaft 22 is a gear 26 , which in turn is coupled to a further gear 26 of the transmission 12 . The transmission 12 includes a further transmission shaft 30 and corresponding bearings 24 for the transmission function. Furthermore, a sensor unit 32 can be arranged on the drive shaft 22 in order to determine, for example, a rotational speed or a shaft position.

[0032] The electric motor unit 16 is surrounded by an electric motor housing 34 , which can be a steel sheet housing, for example. The electric motor housing 34 can have openings which can allow ...

Abstract

A drive unit (10) for a motor vehicle is proposed, having a transmission (12), a transmission housing (14) and an electric motor unit (16) with a stator (18) and a rotor (20). The transmission housing (14) has an interior space, wherein the transmission (12) is received in the interior space. The electric motor unit (16) is arranged in the interior of the transmission housing (14).

Description

technical field [0001] The invention relates to an electric drive or a hybrid drive for a motor vehicle. In particular, the invention relates to a drive unit for a motor vehicle with a transmission and an electric motor unit. Background technique [0002] For driving the motor vehicle, electric motors are increasingly being used which, for example, either exclusively or in combination with conventional combustion motors provide the drive power for driving the motor vehicle. [0003] In the prior art, a large number of electric drives and hybrid drives are described. In this case, for example, the electric machine and / or the combustion motor are coupled via a transmission to the drive train of the vehicle. The transmission can be used here to provide a suitable torque and rotational speed or to convert them into one another. For this purpose, in many cases the electric machine and the transmission can be arranged side by side or in direct spatial proximity in the motor com...
