Problems solved by technology

[0004] A disadvantage of these known hybrid drives is that the multiple drive shafts and their associated couplings in the water transmission make the construction of the device very complex, which not only results in high costs but also creates a considerable space requirement, so this The use of similar hybrid drives is limited in tight installation conditions (e.g. in port tugboats) and requires a special hull design, and it is usually not possible to additionally equip ships with an internal combustion engine as a primary drive motor. like hybrid drives, or can only be realized in a very complex way

Embodiment Construction

[0033] figure 1 Shows a schematic diagram of a marine transmission of a hybrid drive, wherein the marine transmission 1 comprises a drive shaft 11 extending approximately horizontally in a transmission housing 10, which is driven as an L-shaped drive via an angle transmission 12 with bevel gears A vertically extending vertical shaft 13 protrudes from the housing 10 of the marine transmission 1 . The components shown in this figure are generally arranged inside the vessel, not shown here.

[0034] The vertical shaft 13 leads in a manner not shown in detail to a rudder oar arranged on the outside of the ship, more precisely under the hull, in a conventional embodiment as shown in DE 20 2009 009 031 U1.

[0035] The drive shaft 11 is driven with power and torque M by a primary drive motor, not shown here, which is also arranged inside the vessel, for example an internal combustion engine.

[0036] The coupling to the drive shaft 11 can be established or decoupled via the coupli...

Abstract

A hybrid drive for a watercraft, including a primary drive motor, which is situated inside the watercraft and drives a drive shaft, and an above-water transmission, which is situated after the drive shaft and has a transmission housing, for driving a vertical shaft branching off from the above-water transmission, as well as an electric secondary drive motor, which has a stator and a rotor and is able to drive the vertical shaft in addition to or alternatively to the primary drive motor. The secondary drive motor can be embodied with a hollow shaft and the stator of this motor can be coupled in a torsionally rigid fashion to the transmission housing of the above-water transmission.

Description

technical field [0001] The present invention relates to a hybrid driving device for a ship, comprising a primary drive motor, a water transmission device and at least one electric secondary drive motor, the primary drive motor is arranged inside the ship and drives a drive shaft, the water drive a transmission is provided downstream of the drive shaft, comprises a transmission housing and is adapted to drive a vertical shaft extending from the above-water transmission, the at least one electric secondary drive motor may assist or replace the primary drive motor in driving the vertical axis. Background technique [0002] For example, WO 2011 / 021727 A1 discloses a hybrid driving device of the same type for driving the rudder propeller. The propeller shaft of the rudder propeller is located outside the hull. Primary drive motors and / or secondary drive motors inside the vessel are driven via vertical shafts. A coupling can be used to establish a dynamic coupling between the pr...
