Abstract

A drive device for a motorcycle is provided. The drive device includes an internal combustion engine having an adapter assembly arranged on a first end face of the internal combustion engine. The adapter assembly on a connection face opposite the first end face at least two connection geometries for different electrical drive units.

First claim

What is claimed is:

1. A drive device for a motorcycle, comprising:
an internal combustion engine having a first end side and a second end side located opposite the first end side; and
an adapter unit having a coupling end side and a connection end side located opposite the coupling end side,
wherein
the end sides of the internal combustion engine and the adaptor assembly are oriented in each case perpendicularly to spindles and shafts of the internal combustion engine and of the adapter unit,
the adapter unit is arranged on the internal combustion engine such that the first end side of the internal combustion engine and the coupling end side of the adaptor assembly abut one another, and
the connection end side of the adaptor assembly has at least two connection geometries for different electric drive assemblies.

2. The drive device according to claim 1 , wherein
the internal combustion engine is constructed a flat engine.

3. The drive device according to claim 1 , wherein
the at least two connection geometries on the connection end side of the adapter unit include
a first connection geometry for a starter motor,
a second connection geometry for a generator,
a third connection geometry for an electric drive unit, and
a connection geometry for a starter generator.

4. The drive device according to claim 2 , wherein
the at least two connection geometries on the connection end side of the adapter unit include:
a first connection geometry for a starter motor,
a second connection geometry for a generator,
a third connection geometry for an electric drive unit, and
a connection geometry for a starter generator.

5. The drive device according to claim 1 , wherein
the adapter unit includes a gearwheel system configured to transmit torque between the internal combustion engine and at least one of the at least two connection geometries.

6. The drive device according to claim 3 , wherein
the adapter unit includes a gearwheel system configured to transmit torque between the internal combustion engine and at least one of the at least two connection geometries.

7. The drive device according to claim 5 , wherein
the gearwheel system is configured to transmit a mechanical torque which is at least 30% of the maximum mechanical torque output of the internal combustion engine.

8. The drive device according to claim 1 , further comprising:
a clutch unit arranged on the second end side of the internal combustion engine; and
a transmission unit,
wherein the clutch unit is configured to control transmission of toque from the internal combustion engine to the transmission unit.

9. The drive device according to claim 5 , further comprising:
a clutch unit arranged on the second end side of the internal combustion engine; and
a transmission unit,
wherein the clutch unit is configured to control transmission of torque from the internal combustion engine to the transmission unit.

10. The drive device according to claim 6 , further comprising:
a clutch unit arranged on the second end side of the internal combustion engine; and
a transmission unit,
wherein the clutch unit is configured to control transmission of torque from the internal combustion engine to the transmission unit.

11. The drive device according to claim 8 , wherein
the transmission unit is arranged beneath the internal combustion engine between the first end side and a second end side of the internal combustion engine, and
an output shaft of the transmission unit extends through an opening in the adapter unit.

12. The drive device according to claim 9 , wherein
the transmission unit is arranged beneath the internal combustion engine between the first end side and a second end side of the internal combustion engine, and
an output shaft of the transmission unit extends through an opening in the adapter unit.

13. The drive device according to claim 10 , wherein
the transmission unit is arranged beneath the internal combustion engine between the first end side and a second end side of the internal combustion engine, and
an output shaft of the transmission unit extends through an opening in the adapter unit.

14. A motorcycle, comprising:
wheels;
an internal combustion engine having a first end side and a second end side located opposite the first end side, the internal combustion engine being arranged to supply torque to at least one of the wheels; and
an adapter unit having a coupling end side and a connection end side located opposite the coupling end side;
a clutch unit arranged on the second end side of the internal combustion engine; and
a transmission unit,
wherein
the end sides of the internal combustion engine and the adaptor assembly are oriented in each case perpendicularly to spindles and shafts of the internal combustion engine and of the adapter unit,
the adapter unit is arranged on the internal combustion engine such that the first end side of the internal combustion engine and the coupling end side of the adaptor assembly abut one another,
the connection end side of the adaptor assembly has at least two connection geometries for different electric drive assemblies,
the adapter unit includes a gearwheel system configured to transmit torque between the internal combustion engine and at least one of the at least two connection geometries, and
the clutch unit is configured to control transmission of torque from the internal combustion engine via the transmission unit to the at least one of the wheels.
