Improvements to the drive systems for boats capable of passing of the running at high speed is that a reduced speed.

摘要

P the system comprises a clutch 5 which makes it possible to connect an input shaft 1 has an output shaft 18. In order to make it possible to pass to the running speed reduced, it is made of a mechanism planetary 9, the ring 11 may be blocked by a brake 23. By placing the clutch 5 out of action and by slowing down the ring, it is possible to ensure the operation by an auxiliary motor coupled to the central pinion of this mechanism. Conversely, by freeing the ring and by putting into action the clutch, it is the main motor, which takes place by the shaft 1. A second clutch connects to the first by the teeth 21, 22 and which corresponds to a second mechanism planetary the back. / p
