Definitions

  • the scope of this invention generally relates to the sector of marine propulsion systems mounted on the stern of vessels.
  • the invention relates to oleodynamic means for said marine propulsion systems suitable for making it possible to vary the operating positions of the stern unit.
  • the invention provides an optimized technological solution for an apparatus used to connect and support the stern unit of a vessel capable of allowing for its movement, with the purpose of achieving numerous operating arrangements of propulsion.
  • An outboard motor is a marine engine which generally adopts a two-stroke or four-stroke explosion engine, be it a gasoline engine or a diesel engine, or an electric motor or other known hybrid motors, manufactured and used for being mounted in the transom of a vessel. Said motor makes the power transmitted to a (fixed) rotary shaft coming out from the transom, available.
  • Outboard motors comprise an engine external to the hull, supported by an external skeg (stern drive) comprising the transmission members used to transfer motion to a propeller; the direction of a vessel's movement can be modified by rotating the skeg, without using a rudder as with inboard motors.
  • stern drive stern drive
  • the skeg can be adjusted horizontally, either rightwards or leftwards, in order to direct the hull, but it can also be adjusted vertically, either downwards or upwards, in order to obtain a tilt effect and, above all, to set the trim position which, besides providing transportation and safety in case of collisions, also allows to modify performances, i.e. the trim of propulsion or alternatively, to take it out of the water during a stop, to haul the boat, or to make repairs.
  • An adjustment of the trim of said motors is necessary to reduce or increase friction with the water in order to obtain an optimum trim during navigation; if friction is decreased, i.e. the propeller of the motor is raised upwards to try and make it come out from the water, the boat will tend to plane and increase its own speed by some knots, an operation that results in also consuming less fuel because of a reduced friction.
  • connection systems and devices are known for outboard motors, which allow to adjust the tilt and raising/lowering positions of a propeller in order to achieve the advantages of the principles as mentioned here above.
  • Said systems comprise propeller raising and lowering devices, which include one or more tilt cylinders basically used for raising the propeller out of the water and lowering it into the water, and one or several trimming cylinders basically used for changing the angle of the propeller underwater.
  • Document JP19840056268 discloses a number of embodiments of a hydraulically controlled unit equipped with cylinders for varying tilt and trim of outboard motors.
  • the rods of the pistons of the tilt and trim cylinders are arranged in such a way that they are out of the water whenever the outboard motor is tilted upwards.
  • Some embodiments use such connection system that the external unit will be displaced so as not to significantly increase the actual length of the associated ship whenever the external unit is tilted upwards.
  • Document US19950486527 discloses a marine propulsion device comprising a tilt/trimming and raising regulation mechanism which allows to vary trim of transmission by keeping a determined angle.
  • the regulation mechanism includes a four-bar linkage system provided with upper leverages comprising a pair of tilt and trim actuators, which vary the length of the upper linkage so as to adjust stern transmission trim and upwards tilt, and lower leverages comprising two flexible joints of a transmission gear set.
  • One of these flexible joints is coupled with a lower drive unit in the stern unit which enables the lower leverages to rotate without modifying the trim angle of the lower transmission unit.
  • Document US20010806719 discloses a vertical trim variation system for an outboard/inboard marine motor comprising a stern plate and arms whose first ends are attached to the plate of the transom and the second ends are attached to a plate connected to the motor.
  • Document EP0251995A2 relates to a naval propulsion plant that provides a pair of heat engines that drive two independent pumps. In turn these pumps drive two hydraulic motors with which two propellers are solid in rotation. A suitable distributor makes it possible to idle one of the two propellers in case of a breakdown, or to operate both with one of the heat engines.
  • none of the systems comprises a regulation mechanism capable of regulating trim, raise, and rotation of an oleodynamic azimuth stern that allows to vary its trim via an oleodynamic transmission directly connected to the engine unit of a vessel.
  • No devices are known either that allow for a propeller, hydraulically fed by a pressurized circuit of a vessel, to perform different functions, such as, for example, that of an outboard motor or that of a surface propeller, and to vary its trim without being obliged to stop it.
  • An object of the present invention is to provide a connection and support apparatus for a stern marine propulsion unit provided with oleodynamic means (oleodynamic azimuth stern or azipod) capable of making it possible to vary the operating positions of the unit and allowing its movement in order to obtain numerous operating trims for the propellers. More specifically, an object of the present invention is to provide a propulsion system for vessels that is capable of providing the following movement options for a stern unit either individually or simultaneously:

  • connection means 200 consist of quick-release mechanical and hydraulic attachments.
  • Said oleodynamic means 17, 18 are piston- and cylinder-based oleodynamic means whose pistons are opposed so as to rotate around one and the same pin at different angles.

  • Figure 8 illustrates the activation of the oleodynamic means 17 supplied by the oleodynamic fluid passing through the connection means 200, 500, which determines a rotation of the oleodynamic kinematic mechanism 1 around the Y axis of the oleodynamic cylindrical pin 5 and the consequent raising or lowering of the oleodynamic azimuth stern;
  • the two overall side views show the oleodynamic azimuth stern provided with the apparatus in a position a) whereby it is raised (torpedo partially rising out) and in a position b) wherein it is lowered (torpedo totally submerged) respectively;

  • Figure 9 illustrates the activation of the oleodynamic means 18 supplied by the oleodynamic fluid passing through the connection means 200, 500, 100, 600 which determines a rotation of the oleodynamic azimuth stern 1 around the Z axis of the oleodynamic cylindrical pin 6 and the consequent trimming of the oleodynamic azimuth stern; the two overall side views show the oleodynamic azimuth stern provided with the apparatus in a counterclockwise trimming position a) (torpedo's propeller rising off) and in a clockwise trimming position b) (torpedo's propeller submerged).
  • Rotation of the oleodynamic azimuth stern A around its own vertical axis X takes place by way of an oleodynamic motor 30, arranged above the rotary joint 3, directly supplied by the connection means 200; the oleodynamic motor 30 triggers the activation of a gear mechanism 31 integral with the rotary joint 3 and a rotation from 0° to 360° around the X axis of the oleodynamic azimuth stern A.
  • the rotary joint makes it possible for oil to flow to the oleodynamic motor placed in the torpedo under any angles of rotation of the torpedo.

  • the specifically designed connection plate provided with quick release mechanical and hydraulic attachments makes it possible an easy and quick connection of the apparatus to the transom of the vessel.
  • Another outstanding features of the apparatus is in that, being the azimuth stern connected to oleodynamic cylinders and being these provided with shut-off and pressure relief valves, in the case of a collision with dead bodies, the stern raises up and softens the collision, because the pressure relief valves in the cylinders discharge the excess pressure, thus resulting in raising it up.
