Description

The invention relates to a cycloidal drive according to the preamble of claim 1 and a ship, in particular motor glider, with the features of claim 9.

Cycloidal drives, also called Voith-Schneider motors / drives, have the advantage of ensuring great maneuverability for ships. Here, a plate is rotated and arranged underwater profiles are employed according to the respective target (propulsion steering, etc.) depending on the rotation angle.

Motor gliders or ships with, for example, a Flettner drive, are usually equipped with additional engines, which can ensure a progress of the ship in the doldrums. In addition, such ships must have corresponding rudder systems, so that a steering of such ships is possible. In particular, if the drive is a screw drive in such motor gliders, this is unfavorable for the case when the motor glider is in sole sailing operation. The rudder profiles or the rotor blades of the water flow bring a resistance, so that the sail propulsion is reduced.

In addition, when sailing in pure sail propulsion takes place an inclination of the ship, which leads to a so-called drifting. This drift corresponds to a deviation from a predetermined course, which is corrected for example by rudder interventions.

The object of the invention is to improve the state of the art.

The problem is solved by a cycloidal drive with the features of claim 1. Advantageous embodiments result from the subclaims.

Due to the proposed cycloidal drive, an underwater profile can be set so that, in particular in pure sail propulsion, the water is provided with as little resistance as possible, or a rowing motion is impressed on the vessel by a slight hitch. In particular, when using several underwater profiles can thus be done an effective rowing.

Thus, in particular the horizontal drive, which is also called plate, are locked, and only the Verstellprofile be used that either a corresponding rowing or a certain rudder effect is effected.

In addition, this cycloidal drive also allows the well-known characteristics of a cycloidal drive (also called Voith-Schneider drive) so that a large maneuverability can be ensured in the event of a doldrums or maneuvering in the port.

In particular, the individual Verstellprofile can be rotated about a vertical axis and adjusted and of course also locked.

Furthermore, so far unknown Verstellprofileinstellungen can be realized. This is particularly possible because individual Verstellprofile are separately controlled and driven and therefore can be set completely independently. Thus, corresponding transmission or other mechanical coupling mechanisms are eliminated.

The locking device makes it possible in particular to detect the horizontal drive releasably. In this (locking) state, the individual adjustment profiles can be controlled.

A regulation of the adjustment profiles can also be done. In particular, suitable sensors such as tilt sensors and / or heading sensors and / or position sensors such as GPS or Gallileo processing sensors can be used for this purpose. As soon as a deviation from a predetermined course is detected, an intervention on the adjustment profiles can be made such that the rudder effect is used in the locked horizontal drive and thus takes place at full sailing power steering and rowing.

In the event that as little resistance as possible is generated during sail operation, the individual adjustment profiles can also be released so that they align themselves in accordance with the water flow.

Thus, the problem is also solved by a ship, in particular a motor glider, which has a previously described cycloidal drive. The features of the ship emerge in particular from claim 9.

With such a ship can thus be provided a motor glider, which has a high maneuverability in a port and on the high seas can turn on or off a drive and on the same time also a rowing of the motor glider is made possible. In this case, the ship has in particular a so-called Flettner drive.

Furthermore, the invention will be explained in more detail with reference to figures. Show

A cycloidal drive 100 has a drive plate 101 and an associated engine 103 on. The motor 103 especially shapes the plate 101 a rotation on. The rotation takes place in particular about the disc rotation axis 111 , Water side are on the plate 101 a first underwater profile 207 , a second underwater profile 105 , a third underwater profile 107 and a fourth underwater profile 109 arranged. Each of the underwater profiles 207 . 105 . 107 . 109 additionally has a separate control unit 113 with electric motors on. The underwater profiles 207 . 105 . 107 . 109 are each 360 ° about a profile rotation axis 233 rotatable.

In the classic cycloidal drive, the engine shapes 103 the plate 101 a rotation on. According to a rotation angle, the individual underwater profiles 207 . 105 . 107 . 109 employed, so that forms an angle, which leads to a propulsion or other movement.

In the present case, the cycloidal drive is flanged in particular to a motor glider, which has so-called Flettner rotors. For cases where the wind conditions are insufficient to generate sufficient feed, the classic cycloidal drive is used for propulsion.

Once the motor sailer reaches sufficient speed due to the wind conditions, the plate becomes 101 locked.

In a first alternative, the individual underwater profiles are added 207 . 105 . 107 . 109 Approved. By the water flow from a flow direction 221 These underwater profiles are aimed 207 . 105 . 107 . 109 and the resistance of the motor glider is reduced.

In a further alternative, the inclination of the ship is determined by means of a inclinometer in the case of pure sailing operation. Due to the slope, the individual underwater profiles 207 . 105 . 107 . 109 a direction 341 imprinted, so that an angle β with respect to the flow direction 221 formed.

This allows the motor sailer to be given a direction and the motor glider can keep his course.
