Definitions

  • the invention is based on a sterndrive for a watercraft according to the preamble of the first claim.
  • BESTATIGUNGSKOPIE A method is also known from US Pat. No. 4,371,350, in which the inflow of water and thus the depth of the propeller are controlled by means of a flap on the watercraft, with the disadvantage of the rigid propeller shaft.
  • the height of the propeller can theoretically also be changed by a few centimeters via the trim, but at the same time the propeller trim is changed unpleasantly.
  • the invention has for its object to avoid the disadvantages of the prior art in a sterndrive for a watercraft of the type mentioned and to provide a method in which in particular the propeller depth, i.e. the height adjustment of the propeller relative to the fuselage, respectively. Water immersion depth, for the various vehicle conditions and regardless of which the trim can be adjusted for sterndrives.
  • the core of the invention is an intermediate piece which, on the one hand, enables the propeller to be immersed by swiveling the drive and, on the other hand, independently takes over the standard trim of the sterndrive in a functional manner.
  • the advantage of the invention lies in the simple feasibility and simple introduction of such a means into the sterndrive system.
  • the intermediate piece can be found compactly between the sterndrive bell housing and the sterndrive itself and includes the swivel device for the sterndrive, the electric or hydraulic drive, the associated optional angle encoder and the bracket for the trim cylinder or cylinders.
  • the intermediate piece further comprises an intermediate housing which is connected to the bell housing or can be designed as an integral part of the bell housing.
  • the sterndrive no longer has a trim cylinder, this can now be short or short stroke, because in order to safely lift the sterndrive at shallows, among other things, it is now swiveled sideways out of the danger zone by a swivel motor.

  • a possible radial pivoting of the sterndrive 30 is demonstrated by the dashed lines.
  • the immersion depth of the propeller in the water is represented by the water line X.
  • the sterndrive 30 is shown schematically from the side, the intermediate piece 1 being located between the sterndrive and a bell housing 7.
  • the bell housing 7 is held by a cardan housing 8 and enables the bell housing 7 and the components located behind it to rotate about the axis A perpendicular to the plane of the drawing and at the same time about the axis B for controlling the sterndrive 30 for the ship's rudder function.
  • the rotary movement about the axis A is ensured by the trim cylinder 6 which is supported on the intermediate housing 1 and the gimbal housing 8.
  • the immersion depth of the propeller in the water is represented by the water line X. 3 shows a schematic cross section in the area of the intermediate piece 1.
  • the intermediate piece 1 comprises an intermediate housing 24, a swivel inner tube 10, bearing 12, tube holder 13 and the swivel motor 5.
  • the Z drive 30 only shows the upper gear part 2 in this view , which is held firmly by screws 9a with the rotatably mounted inner pivot tube 10.
  • the swivel inner tube 10 has at one point a shoulder 11 which is mounted by means of the thrust bearing 12 against the intermediate housing 24 and a tube holder 13, the tube holder 13 additionally preventing the inner swivel tube 10 from being axially displaced, and thus the bearing play can also be adjusted.
  • the tube holder 13 and or the intermediate housing 24 also has at least one radial bearing 14 for low-friction pivoting of the inner pivot tube 10, respectively. of the sterndrive 30.
  • the shoulder 11 is equipped with a gear rim 15 which can be rotated by a pinion 16.
  • the pinion 16 is by the swivel motor
  • gear pairing such as the swivel mechanism can be made self-locking by a worm gear or by other means.
  • Hydraulic or electrical lines 17 are led out of the intermediate piece 1 and continued into the interior of the watercraft. An is optional
  • Angle encoder 18 installed in the intermediate piece 1, which with the pinion 16 or. can be connected to the swivel motor 5 or the shoulder 11 or other parts not shown and thus indicates an exact position of the propeller 4.

  • the intermediate housing 24 is firmly connected to the bell housing 7 by screws 9b.
  • the intermediate housing 24 can also be integrated into the bell housing 7 and in particular also be made in one piece.
  • the bell housing 7 is pivotally connected to the cardan housing 8 at point A, which in turn is pivotally mounted at point B, for example on a receptacle housing (not shown) or directly on the watercraft body.
  • the intermediate piece 1 is connected to the cardan housing 8 by means of the intermediate housing 24 via the trimming cylinder 6 and allows the Z drive 30 to be raised for trimming.
  • Most sterndrives have a trim sensor, which is integrated at position A and can therefore be maintained.
  • transmission gearwheels 20 and a shaft 21, which is guided through the inner swivel tube 10, the intermediate housing 24, the bell housing 7 and is connected to a motor shaft 22, are shown schematically, with a universal joint (not shown) being located at point A around the flexion angle to enable the shaft to be trimmed via swivel joint A and for rudder steering via swivel joint B.

  • the water supply 36 can on the side wall as a closed channel in the fuselage as shown on the right in Fig. 4, or as a section as shown on the left in Fig. 4, which is in Fuselage of the watercraft is located, in order to achieve the appropriate propeller flow.
  • the water supply 36 or the water supply opening 38 can be open or closed, i.e. Corresponding flaps cover the water inlet opening when not in use or such flaps are missing, as in the cutout in the hull of the watercraft according to FIG. 4 on the left.
  • the drive 30 can be pivoted laterally until it comes to rest at the level of the water supply 36.
  • the water for the propeller thrust is therefore no longer absorbed below the hull of the watercraft, but practically behind and in the protection of the rear wall 35 of the watercraft 31 and the journey can be continued at places which would otherwise be impassable for watercraft with a Z drive due to the shallow water would.
  • the water supply corresponds to the advantages and power output similar to a jet drive.
  • Another advantage is that, on the one hand, the propeller is protected from contact with the ground, and on the other hand, seaweed can still be easily removed from the open propeller area, for example by additional means Swiveling the drive sideways until the drive 30 and the propeller 4 appear even above the water surface.
  • the drive 30 and the propeller can also additionally be designed to be longitudinally pivotable, as described above, i.e. in the longitudinal direction / in the direction of the axis of the watercraft.
  • This trimming also known as trimming, in the longitudinal direction by a few angular degrees helps to keep the bow of the watercraft calm in choppy water, or to become faster.
  • Sterndrives do not have a space problem in the cockpit, but the change in the thrust angle as well as the additional space required at the rear of the vehicle when the drive swings up remains.
  • the underwater gear can be swiveled over a large angular range to this extent and without any loss of power allows the propeller to be operated as a surface propeller drive, i.e. the propeller is only used partially submerged and is used in high-speed watercraft.
  • a modified stern section is used, which is located above the waterline when gliding and at the end of which the swivel section for the underwater gear is attached.
