The invention relates to a rudder for sea vessels, consisting of a main rudder and a fin which is coupled thereto by means of a vertical piston (15), restrictively guided by the main rudder and provided with a horizontal piston (11) The vertical piston (15) and the horizontal piston (11) are connected to each other via a hinge bolt to form a sliding pivoting piston coupling (100) and a bearing housing (16) of the vertical piston (15) is fixed to the hull of the vessel. In order to reduce the forces acting upon the sliding bearing of the vertical coupling bolt and horizontal pivoting bolt in addition to the hinge bolts connecting said bolts, the vertical piston (15) is supported by an additional counter bearing (27) on the hull of the vessel.

L'invention concerne un gouvernail de navires de haute mer, comprenant un gouvernail principal et un aileron articulé au gouvernail principal par un piston vertical (15) et à guidage forcé par le gouvernail principal, l'aileron étant doté d'un piston horizontal (11). Le piston vertical (15) et le piston horizontal (11) sont reliés par un boulon charnière pour former une articulation à piston rectiligne basculant (100) et un boîtier logement (16) du piston vertical (15) est fixé à la coque du bateau. Pour réduire au minimum les forces agissant sur le palier lisse du boulon d'articulation vertical et du boulon basculant horizontal ainsi que sur le boulon charnière (14) reliant ces deux boulons, le piston vertical (15) est pressé sur la coque de bateau par un contre-palier (27) supplémentaire.
