Abstract
A marine transmission (1) with a main driveshaft (3), a first intermediate shaft (4) and a drive output shaft (6), by way of which at least one propeller (21) can be driven. The marine transmission (1) has an electric machine (7), as an additional drive, a second intermediate shaft (5) and a planetary gear assembly (8). The electric machine (7) can be connected to the second intermediate shaft (5) by way of the planetary gear assembly (8). Also a drive arrangement for a marine transmission with a main drive motor (2) and with a marine transmission (1) of that type are disclosed.
Claims8
A marine transmission comprising:
- a main driveshaft that is connectable to a main drive motor,
- a first intermediate shaft,
- a second intermediate shaft,
- a drive output shaft by way of which at least one propeller is drivable,
- a drive output gearwheel, arranged on the drive output shaft, being engaged with a first driving pinion, a second driving pinion and a third driving pinion,
- the first driving pinion being connectable, by a first powershiftable clutch, to the main driveshaft,
- the second driving pinion being connectable, by a second powershiftable clutch, to the first intermediate shaft,
- the third driving pinion being rotationally fixedly connected to the second intermediate shaft,
- the marine transmission comprising an electric machine, as an additional drive, and a planetary gear assembly, and
- the electric machine being connectable to the second intermediate shaft of the marine transmission by the planetary gear assembly.
A marine transmission comprising:
- a main driveshaft,
- first and second intermediate shafts
- a drive output shaft,
- the main driveshaft being connectable to a main drive motor which drives, via the drive output shaft, at least one propeller,
- a drive output gearwheel, arranged on the drive output shaft, being engaged with first, second and third driving pinions,
- the first driving pinion being connectable, by a first powershiftable clutch, to the main driveshaft,
- the second driving pinion being connectable, by a second powershiftable clutch, to the first intermediate shaft,
- the third driving pinion being fixedly connected to the second intermediate shaft,
- the marine transmission comprising an electric machine, as an additional drive, and a planetary gear assembly, and
- the electric machine being connectable, via the planetary gear assembly, to the second intermediate shaft of the marine transmission.
