Drive system for a hybrid motor vehicle with convertible direct through-drive for a wheel, and motor vehicle

Abstract

The invention relates to a drive system (1) for a hybrid motor vehicle (31), comprising a motor shaft (4) which is rotationally coupled or can be rotationally coupled to the output shaft (2) of an internal combustion engine (3), a first electric motor (6) which has a first rotor shaft (5) and which is operated as a generator in a main operating state, a second electric motor (8) which has a second rotor shaft (7) arranged in a radially offset manner to the first rotor shaft (5) and which is operated as a drive motor in the main operating state, a drive part (10) which is rotationally connected to the second rotor shaft (7) and which can be rotationally connected to at least one wheel (9a, 9b) of the motor vehicle (31), and a transmission unit (11) which can be shifted and which is operatively installed between the motor shaft (4), the two rotor shafts (5, 7), and the drive part (10). A shift device (12) which controls the shift position of the transmission unit (11) is operatively installed between the motor shaft (4), a first gear (13), which is permanently rotationally coupled to the first rotor shaft (5), and a second gear (15), which is permanently rotationally coupled to the second rotor shaft (7) via an additional planetary transmission stage (14), such that the shift device (12) rotationally connects the motor shaft (4) to the first rotor shaft (5) while the second rotor shaft (7) is rotationally decoupled from the motor shaft (4) in a first shift position, the shift device rotationally connects the motor shaft (4) both to the first rotor shaft (5) as well as to the second rotor shaft (7) in a second shift position, and the shift device rotationally connects the two rotor shafts (5, 7) together while the motor shaft (4) is rotationally decoupled from the two rotor shafts (5, 7) in a third shift position. The invention additionally relates to a motor vehicle (31) comprising said drive system (1).

Description

Technical field [0001] The present invention relates to a drive system for hybrid motion vehicles, which is preferably implemented as a series hybrid drive. The drive system typically has two electric motors: the first electric motor mainly used as a generator and a second electric motor mainly used as the drive motor. The drive system also has a transmission unit, and the transmission unit operatively connects the output shaft, electric motor, and output side driving portion of the internal combustion engine. The invention also relates to a motor vehicle comprising the drive system. Background technique [0002] According to the prior art, universal drive systems have long known. For example, DE 10 2017 206510 A1 discloses a transmission structure for a series / parallel hybrid vehicle. [0003] Therefore, the driving system of "series" mixed power can be achieved is already known, in which the driving wheel / wheel of the internal combustion engine to the motor vehicle can be p...

Problems solved by technology

A further disadvantage of the known embodiment is that the two front electric motors are usually arranged axially next to each other in a row, which is disadvantageous in the case of a front transverse design of the internal combustion engine, and especially in the case of small vehicles. questionable
