Abstract

The invention relates to a hybrid module for installation between an internal combustion engine (6) and the transmission (4) of a watercraft, the flywheel being located in a conventional way in the housing of the internal combustion engine (6). It is characterized in that the hybrid module (7) is external to the housing of the internal combustion engine (6) and comprises a housing (8), a generator/motor (11) within the housing, and suitable shifting elements (10) for optionally coupling the transmission (4) with the internal combustion engine (6) and/or the generator/motor (11).

Claims

1. A hybrid module for installation between an internal combustion engine and a transmission of a watercraft, a flywheel being located in a conventional way in a housing of the internal combustion engine, the hybrid module comprising:

a housing, a generator/motor within the housing, and suitable shifting elements for selectively coupling the transmission to the internal combustion engine and/or the generator/motor, wherein said hybrid module is external to the housing of the internal combustion engine.

2. A hybrid module according to claim 1, said hybrid module is configured so as to be installed in the watercraft as a separate part in the form of a sandwich.

3. A hybrid module according to claim 1, wherein the housing is configured as an extension of a transom panel or of a transom housing of the transmission.

4. A hybrid module according to claim 1, wherein electrically changing a sense of rotation of the generator/motor in an electric motor mode of propulsion produces backward motion of the watercraft.

5. A hybrid module according to claim 1, wherein the shifting element is a freewheel.

6. A hybrid module according to claim 1, wherein the shifting element is a positive locking coupling with one, two or three positive locking clutches.

7. A hybrid module according to claim 1, wherein the shifting element is a frictional coupling having one, two or three friction clutches.

8. A hybrid module according to claim 1, wherein the generator/motor is annular and disposed concentric with a main shaft and the shifting element.

9. A hybrid module according to claim 1, wherein the generator/motor is compact and disposed parallel to a main shaft, and drives the shaft using a spur gear set, a chain drive, or a belt drive.

10. A hybrid module according to claim 1, wherein the generator/motor is compact and disposed at an angle to the main shaft, and drives the shaft using conical gears, crown gears, or a worm gear.

11. An application of a hybrid module according to claim 1, wherein the hybrid module is used as a sandwich part with suitably configured housing mounting flanges for diverse internal combustion engines and diverse drive systems.

12. A hybrid according to claim 6, wherein the positive locking clutch or clutches of the positive locking coupling are dog clutches or synchronizing means.

13. A hybrid according to claim 7, wherein the friction clutch or clutches of the frictional coupling are wet multiple disk clutches or dry clutches.
