Abstract

A hybrid drive arrangement for a vehicle with a powertrain includes an internal combustion engine, a transmission with a variable gear ratio and defining a driving side and a driven side, at least one electric machine disposed on the driving side and an acceleration element disposed on the driving side of the transmission. The electrical machine is operable as a motor and as a generator, and the acceleration element may include at least one hydrodynamic converter or at least one clutch and at least one gear ratio component.

Claims

1. A hybrid drive arrangement for a vehicle with a powertrain comprising:

an internal combustion engine;

a transmission with a variable gear ratio and defining a driving side and a driven side;

at least one electric machine disposed on the driving side, the electrical machine operable as a motor and as a generator; and

an acceleration element including at least one hydrodynamic converter disposed on the driving side of the transmission.

2. The hybrid drive arrangement as recited in claim 1, wherein the hydrodynamic converter is disposed between the electric machine and the transmission.

3. The hybrid drive arrangement as recited in claim 1, wherein the hydrodynamic converter is connected to an output shaft of the internal combustion engine.

4. The hybrid drive arrangement as recited in claim 1, further comprising at least one of an additional acceleration element and a decoupling element connected to the powertrain.

5. The hybrid drive arrangement as recited in claim 4, wherein the at least one of an acceleration element and a decoupling element includes a first clutch is connected to an output shaft of the internal combustion engine.

6. The hybrid drive arrangement as recited in claim 1, further comprising a second clutch disposed on the driven side of the electric machine.

7. The hybrid drive arrangement as recited in claim 4, wherein the at least one acceleration element and/or decoupling element includes a second clutch disposed on a driven side of the hydrodynamic converter.

8. A hybrid drive arrangement for a vehicle with a powertrain, comprising:

an internal combustion engine;

a transmission with a variable gear ratio;

at least one electric machine disposed on a driving side of the transmission, the at least one electrical machine being operable as a motor and as a generator;

an acceleration element including at least one clutch and at least one gear ratio component disposed on the driving side of the transmission.

9. The hybrid drive arrangement as recited in claim 8, wherein the gear ratio component has a constant gear ratio.

10. The hybrid drive arrangement as recited in claim 9, wherein the gear ratio component includes at least of a spur gear component and a bevel gear component.
