Definitions

  • the invention relates to a device for automatically controlling a maritime vehicle, the device having a control drive, the one Planetary gear connected with at least one internally toothed ring gear is.
  • z. B mechanical couplings, in particular electromechanical clutches, used that the frictional connection between the steering gear and the oars.
  • the planetary gear serves the rotary movement emitted by the control drive To reduce in at least one gear stage so far that at the oars sufficient taxpayer is available.
  • the invention has for its object a device of the beginning to point out the type mentioned, which is particularly small and the above Avoids disadvantages.
  • the planetary gear has an actuatable circulation lock for the ring gear.
  • the coupling created in this way is thus in the structure of the planetary gear integrated, so that particularly compact as well as small structural dimensions can be realized.
  • control device that can be overcome with a manually operated that the degree of translation, which is perceived as disadvantageous, is significantly reduced, because the downforce is on the path of lower resistance, that is, over the Ring gear can be done.
  • the ring gear with slide or roller bearings in Support planetary gear so that with the device according to the invention also a manually operated control unit particularly friction as well can be operated quietly.
  • the device according to the invention by at least one automatically and / or manually excitable electromagnet marked to activate the circulation lock.
  • electromagnet have short switching times, so that the circulation lock with a Electromagnets can advantageously be switched quickly.
  • the device To deactivate the circulation lock, the device according to the invention a spring element corresponding to the electromagnet.
  • the spring element is designed so that its maximum spring force is less than the attraction force of the electromagnet. It follows that the circulation block is only active as long as a switching current that generates the attractive force applied to the electromagnet.
  • the circulation lock has at least a slidably mounted in the housing of the planetary gear Locking element, which is preferably designed as a cylindrical locking pin is.
  • This preferably has one at one of its two ends Permanent magnet, which forms a first pole of the electromagnet.
  • the second pole of the electromagnet is created with a magnetic coil, which is also advantageously integrated into the housing of the planetary gear.
  • the circulation block several, preferably two slidably mounted in the housing of the planetary gear and has mechanically coupled locking members.
  • the blocking elements in the manner of a claw coupling, based on the Circumference of the internally toothed ring gear, evenly distributed in the housing arranged.
  • the opposite of the permanent magnet free end of the locking member is designed as a locking lug that with at least one recess arranged in the wheel body of the ring gear in Intervention can be brought.
  • the depression is preferably in the outer Area of one of the end faces of the wheel body, so that the locking pin for Axis of rotation of the ring gear can be arranged in parallel.
  • the depression on the outer, facing away from the internal toothing Attach the outer surface of the wheel body so that the locking pin, based on the axis of rotation of the ring gear, has a radial orientation.
  • the latch and the recess each corresponding, tapered or beveled contact surfaces exhibit. This ensures that from the adhesion between Steering drive and rudders when the load limit is exceeded or a predetermined permissible drive torque a force component results, which interrupts the adhesion automatically.
  • the beveled or beveled Contact surfaces cause the distribution of the drive torque resulting locking force applied to the locking lug in a radially directed and in an axially parallel force component. If the axially parallel force component exceeds that from the tightening force of the Electromagnet and spring force resulting force, the shifts Locking pin automatically. The locking lug slips out of the recess, whereby their bevelled contact surfaces slide apart.
  • the drawing shows a planetary gear 1 with a ring gear 2 for an inventive Device for the automatic control of a maritime Vehicle.
  • the planetary gear 1 has an actuatable circulation lock 3 for the ring gear 2.
  • circulation lock 3 To activate circulation lock 3, two are automatic here and / or manually excitable electromagnet 4 is provided.
  • To deactivate the circulation lock 3 serves a corresponding to the electromagnet 4 Spring element 5, which is designed as a spiral compression spring.
  • the circulation barrier 3 is completely integrated in the housing 6 of the planetary gear 1, and has a displaceably mounted locking member 7, which is designed as a cylindrical Lock pin is formed.
  • the ring gear 2 has one in an end face 8 of the end faces of its wheel body arranged recess 9, with which a free end of the locking member 7 forming latch 10 can be brought into engagement.
  • the latch 10 and the recess 9 have mutually corresponding, beveled or beveled Contact surfaces 11, 12 to form an overload protection.
  • the free end of the locking member 7 facing away from the latch 10 has a permanent magnet 13 on which the locking member 7 surrounding magnetic coil 14 corresponds.
  • the housing 6 of the planetary gear 1 is driven by a motor 15 and limited on the output side by a bearing cover 16.
  • the housing 6 each has one the bearing cover 16 closable receiving space 17, the preferably as a cylindrically shaped lowering of the locking member 7 in formed on the ring gear 2 recess 9 leading bore 18 is.
  • the permanent magnet 13 is on the locking member 7 by a recording head 19th held, the adjacent to the solenoid 14, and that as a helical compression spring trained spring element 5 compressing the circulation lock 3 shows in activated state.
