Planing device for the multiplication of

Forces (

In the known lever devices for multiplying forces, d. H. for devices in which one on the Input (part of a lever) applied command force at the output (another part of the lever) around a certain If the ratio occurs multiplied, the path amplitude of the input and the path amplitude of the output are always available in an inverse relationship to the forces.

The invention is based on the object of creating a lever device for the multiplication of forces, in which the movement amplitude of the output, i.e. the point at which the increased force is gained and the amplitude of movement of the entrance, d. H. of the point at which the force to be multiplied acts, in relation to one another stand, which is independent of the multiplication ratio of the forces.

The multiplication device of the invention provides this result and is primarily, if not, thereupon limited, suitable for steering large tonnage airships where they are downstream or downstream of the Pilot operated control member or control stick is arranged, ie. upstream or in front of the pilot station, or in other words, in front of the unchecked (indirect) point of intervention, in order to ensure a level of stress that is tolerable for the pilot.

The invention is based on a device for multiplying forces, which has at least one multiplier lever owns. The invention consists in that the multiplier lever is mechanically attached to the moving part of a fixed force relay is articulated and that a point of the multiplier lever is forcibly guided in such a way that this is artificially to real fulcrum, which allows the relationship between the input and output movement to be independent to make of the force multiplication ratio.

In the event that the increased force is near the entry point the command force is to be gained and that both forces are to be directed in the same direction is in Another embodiment of the invention provides that the increased force liflfeanide point of the multiplier lever with the end of a feeder that can be rotated around a fixed point

2OS824 / Ö744

Lever is connected, the other end of which is close to the point of application the command force is ordered.

Further advantages and features of the subject matter of the invention emerge from the following description of the embodiment shown in the drawing, in which the Riultiplikationsheiehung between the forces "4" and the relationship between the movements is "1" and in which the movement of the input point of the command force and the i

Movement of the point at which the increased force is regained are directed in the same direction and approximately one represent mutual extension.

In the exemplary embodiment, it is also assumed that the force relay is a double-acting hydraulic Piston / cylinder unit is used, the control of which takes place via a pressure medium distributor, which is connected to the multiplier lever connected.

In the drawing, 1 denotes the multiplier lever, at the end of which JL engages the command force while the increased force at the end of B is gained · The lever 1 branch at 2 to the piston rod 3 & a fixed pressure fluid cylinder 3 arranged, which is controlled by a fixed distributor 4-, which is controlled by a piston rod 5 is hinged to a point 6 of the lever 1.

The device works as follows: When the cylinder / piston unit 5 is in cows, the remains Funct 2 immobile; if you have an afterthought on point A. exerts, the distributor, which is in its neutral position, is actuated, which is the piston / cylinder unit 3 lets work until in a new position in which the lever 1 is used, the lever the point has brought into a position, which the return of the distributor corresponds to its neutral position. In reality, the processes take place as if the lever 1 around the Point 6, which marks the neutral position of the distributor, would have been pivoted.

To at point B the same movement £ v / ie the movement £ am To get point A, point 6 must be in the middle between points A and B.

To obtain a multiplication relationship between the forces equal to "4", the distance between points 2-B be equal to a quarter of the distance between points A-B.

In order to be able to transmit the increased force in the same direction as the command force and to be able to gain it in the height of the command force input point A, the end B of the lever 1 is connected to the end C of a forward lever 8 via a connecting rod 7.

bond, which is rotatable about a fixed point 9 and whose other end D lying in the vicinity of A thus supplies the reinforced force in the same direction as the command force at point L; the movement of point B is equal to e _t if the pivot point 9 is in the middle between the two points 0 and D »

You can see immediately that for a movement ratio other than 1: 1 it is sufficient to connect the connection point between the lever 1 and the distributor 4 to a suitably selected point other than point 6, which is located in the middle between A and B according to the prerequisite.

In order to achieve a different multiplication ratio, it is sufficient in the same way to attach the piston rod 3 to a suitable, from point 2 different point to be coupled to lever 1 "

It is thus seen that the relationship between the movement of the \ input and at the output of the multiplier is dependent on the position of the point 6 on the lever 1 and that the MuItipiikations ratio between the input and output power from the position of the point 2 on the lever 1 depends .
