Patent ID: 8651905

Claim:
A device for detecting an angular position of a steering shaft ( 8 ) comprising: a boat transmission assembly ( 7 ) comprising: a steering shaft ( 8 ) which swivels an underwater propulsion and steering unit ( 5 ) by a steering angle to achieve a steering effect for the underwater propulsion and steering unit, an angular sensor ( 13 ) for detecting the steering angle of the steering shaft ( 8 ), and an intermediate gear ( 11 ), the steering shaft ( 8 ) is connected to a master gear ( 10 ), the angular sensor ( 13 ) comprises a slave gear ( 12 ), the intermediate gear ( 11 ) is disposed between the master gear ( 10 ) and the slave gear ( 12 ), the intermediate gear ( 11 ) directly engages both the master gear ( 10 ) and the slave gear ( 12 ), the intermediate gear ( 11 ) is a split gear and comprises a first wheel disk ( 11 a ) and a coaxial disposed second wheel disk ( 11 b ), and the coaxially disposed first and second wheel disks ( 11 a , 11 b ) are elastically loaded relative to one another, and the first and the second wheel disks ( 11 a , 11 b ) each have a same tooth gearing (za, zb).
