Problems solved by technology

[0005] However, the prior art has always had the disadvantage that the powertrain of a hybrid vehicle comprising two electric motors and an internal combustion engine takes up a lot of space, especially in terms of its overall length in the axial direction, and due to the large number of components required, such as gears, Gear pairs, bearings and shafts, etc., are also very expensive

Embodiment Construction

[0038] figure 1 A schematic diagram of a powertrain system 1 suitable for a hybrid vehicle according to the present invention is shown. In the drivetrain 1 , a transmission input shaft 2 is operatively coupled to a first electric machine (E-machine) 4 and an internal combustion engine (VKM) 5 via a first drivetrain component 3 for torque transmission. The transmission input shaft 2 is permanently and effectively associated with the second motor (E machine) 7 through the second sub-power assembly system 6 . The second electric machine 7 is connected to the transmission input shaft 2 in all operating states, while the first electric machine 4 and the internal combustion engine 5 can be disconnected from the transmission input shaft 2 via a clutch / release clutch 8 .

[0039] Thus, the first drivetrain component 3 can be connected to the second drivetrain component 6 and thus to the transmission input shaft 2 via the separating clutch 8 for torque transmission. The first motor 4...

Abstract

The invention relates to a powertrain (1) for a hybrid motor vehicle, the powertrain comprising a transmission input shaft (2) which is operatively connected to a first electric machine (4) and an internal combustion engine (5) via a first sub-powertrain (3) so as to transmit a torque and which is operatively connected to a second electric machine (7) via a second sub-powertrain (6) so as to transmit a torque, wherein the second electric machine (7) is permanently connected to the transmission input shaft (2) so as to transmit a torque, and the first electric machine (4) and the internal combustion engine (5) can be connected to the transmission input shaft (2) in a coupleable manner so as to transmit a torque. The first electric motor (4) and the second electric motor (7) are arranged coaxially to each other, and an output shaft (13) of the first electric motor (4) is arranged radially inward of an output shaft (20) of the second electric motor (7). According to the invention, the output shaft (13) of the first electric machine (4) is mounted on the output shaft (20) of the second electric machine (7) by means of a bearing (36).

Description

technical field [0001] The present invention relates to a powertrain system suitable for a hybrid motor vehicle with a transmission input shaft operatively associated with a first electric machine and an internal combustion engine for transmitting torque through a first partial powertrain system and for transmitting Torque is operatively associated with the second electric machine through the second powertrain component. Background technique [0002] Drives suitable for hybrid vehicles are known from the background art. For example, DE 10 2015 222 691 A1 discloses a drive and a method for controlling a drive of a hybrid vehicle, the drive comprising a first electric machine, a second electric machine and a battery. [0003] DE 10 2015 222 690 A1 also discloses a drive unit comprising an internal combustion engine, a first electric machine, a second electric machine and a battery, and a method for controlling a hybrid vehicle drive unit. Wherein, the drive device for drivin...
