## Abstract

The invention relates to a drive device for a hybrid-drive motor vehicle, having an internal combustion engine (12), a variable-speed transmission (14), and an electric machine (32) connected downstream of the variable-speed transmission (14). According to the invention the electric machine (32) is arranged in the motor vehicle as an independent structural unit (16) and is connected by at least one connecting shaft (20, 46) to one of the shafts (38, 40) of the variable-speed transmission (14).

## Claims

### Claim 1

A drive device for a hybrid-driven motor vehicle, comprising:
an internal combustion engine;
a variable-speed transmission;
an independent structural unit arranged downstream of the variable-speed transmission and accommodating an electrical machine with a gear stage;
a shaft directly connected with the variable speed transmission;
a first connecting shaft connected with the gear stage of the electrical machine and coupled with the shaft
wherein the variable speed transmission and the independent structural unit with the electric machine and the gear stage are positioned completely within a central longitudinal tunnel arranged on an underbody of the motor vehicle, and the variable speed transmission and the independent structural unit are each secured in the central longitudinal tunnel by separate mountings to a body of the motor vehicle.

### Claim 2 (depends on 1)

The drive device of claim 1, wherein the central longitudinal tunnel of the underbody of the motor vehicle in which the variable speed transmission and the independent structural unit with the electric machine and the gear stage are positioned has a constant transverse cross section.

### Claim 3 (depends on 1)

The drive device of claim 1, wherein the gear stage is a first gear stage accommodated in the structural unit, said electrical machine having a shaft which is coupled via the first gear stage with the first connecting shaft.

### Claim 4 (depends on 3)

The drive device of claim 3, further comprising a first clutch integrated in the structural unit, said electrical machine including a rotor, at least one member selected from the group consisting of the rotor and the first gear stage being disengageable from the variable-speed transmission via the first clutch.

### Claim 5 (depends on 4)

The drive device of claim 4, wherein the first clutch is placed between the electrical machine and the first connecting shaft upstream of the first gear stage.

### Claim 6 (depends on 1)

The drive device of claim 1, wherein the first connecting shaft is directly connected with the gear stage of the electrical machine.
