Embodiment Construction

[0029] figure 1 A schematic plan view from above of motor vehicle 1 with hybrid drive system 2 is shown. For reasons of clarity, only the body 3 of the motor vehicle 1 is shown schematically. The hybrid drive system 2 of the motor vehicle 1 has two axles 4 , 5 on which wheels 6 are respectively mounted.

[0030] The front axle 4 is driven by an internal combustion engine 7 . The internal combustion engine7 has the figure 1 The common auxiliary units are only partially shown in for drawing reasons. exist figure 1 A starter 8 and a generator 9 are shown in . The starter 8 and the generator 9 are connected to a drive shaft 10 of the internal combustion engine 7 , for example via a V-belt 11 . In an operating state of motor vehicle 1 in which the power generated by internal combustion engine 7 does not need to be fully used to drive motor vehicle 1 , electrical energy is generated by means of generator 9 , which can be intermediately stored in battery 12 .

Abstract

The invention relates to a hybrid drive system (2) for a motor vehicle (1), comprising an internal combustion engine (7) and an electric motor (16) which respectively drives the wheels (6) of the motor vehicle (1). Said internal combustion engine (7) is coupled to the corresponding wheels (6) by means of a first multi-speed gearbox (14). Said electric motor (16) is coupled to the corresponding wheels (6) by means of a second multi-speed gearbox (19).

Description

technical field [0001] The invention relates to a hybrid drive system for a motor vehicle having at least one internal combustion engine and at least one electric motor which each drive at least one wheel of the motor vehicle. Furthermore, the invention relates to a motor vehicle with a hybrid drive system. Background technique [0002] Against the background of rising crude oil prices and the occurrence of global climate change, there is an increasing demand for motor vehicles that consume as little fuel as possible and are fuel-efficient. [0003] A promising solution in this regard consists in the use of motor vehicles with hybrid drive systems. In a hybrid drive system, an additional motor is used in addition to the usual internal combustion engine, which drives the motor vehicle with a different form of energy. In practice electric motors have gained acceptance in this respect. [0004] Through the use of the additional motor, on the one hand the internal combustion ...
