According to the invention, a gravitational unit is provided.

gravitational unit

State of the art

The invention relates to an aggregate for energy production.

There are already known various aggregates for energy.

Advantages of the invention

According to the invention, a gravitational aggregate is proposed. By means of a gravitational aggregate, an advantageous energy utilization of a gravitational force can be achieved.

Preferably, the gravitational aggregate comprises at least one bearing axis and at least one lever which is movable about the bearing axis and which is intended to execute at least one tilting movement about the axis of rotation. A tilting movement can be easily generated by utilizing the gravitational force and is advantageous for energy use. It is further proposed that the gravitational aggregate has an axis of rotation and a crank rotatable about the axis of rotation. Using a crank, the gravitational force can be easily converted into a tilting motion. The crank should in particular be provided to perform at least one pitch circle movement about the axis of rotation. Preferably, the crank is intended to carry out a continuous rotational movement with a defined direction of rotation.

It is also proposed that the bearing axis of the lever and the axis of rotation of the crank are arranged parallel to each other. Thereby, the crank can be operatively connected to the lever, whereby the gravitational force can be used very easily.

In particular, it is proposed that the bearing axis of the lever and the axis of rotation of the crank are arranged offset from one another. As a result, the rotational movement can be used particularly advantageously for energy.

In an advantageous embodiment of the invention it is proposed that the lever is movable by means of a rotary movement of the crank. As a result, the tilting movement can be easily generated.

It is also proposed that the crank is intended to stimulate a linear movement. As a result, the rotational movement can be easily used.

In an advantageous development of the invention, it is proposed that the crank has a weight. This can simply an eccentric mass for generating the movement, in particular a tilting movement and / or a linear movement, are provided, which advantageously has a moving center of gravity during a rotational movement by means of which the tilting movement can be excited.

Also particularly advantageous is an embodiment which has a motor which is provided for driving the crank about the axis of rotation. Thereby, a rotational movement of the crank can be easily maintained, whereby the tilting movement can be maintained.

It is further proposed that the gravitational aggregate has a gravitational compensation unit which is provided to compensate at least partially for a gravitational force acting on the crank. As a result, the rotational movement can be maintained with little effort. In particular, it can be achieved that a small motor is sufficient for maintaining the rotational movement. A "compensation of a gravitational force" is to be understood in particular as meaning that the gravitational force, which acts in particular on the weight of the crank, counteracts a counterforce which deviates from the gravitational force by a definable value and which is preferably approximately the same size.

Preferably, the gravitational compensation unit has at least one spring, which is effectively connected to the crank. By means of a spring, the gravitational force can be compensated for particularly easily. Further, it is advantageous if the gravitational compensation unit has at least one flywheel, which is intended to support a rotational movement of the crank. By means of a flywheel can also be provided an advantageous embodiment to compensate for the gravitational force.

In addition, an embodiment with a gravitational compensation unit is proposed, which has a weight that is operatively connected to the crank. By means of a weight can also be realized an advantageous embodiment. In particular, it is also conceivable to combine a spring, a flywheel and / or a weight to form a gravitational compensation unit.

In a development, it is proposed that the gravitational aggregate has a motion conversion unit which is provided to convert a linear movement and / or a tilting movement into a rotational movement. As a result, the movement of the lever can be advantageously exploited.

Furthermore, in particular a gravitational aggregate composite with at least two gravitational aggregates connected to one another in an operative manner according to the invention is proposed.

Description of the embodiments

FIG. 1 and FIG. 2 show a gravitational aggregate according to the invention. The gravitational aggregate has a stand 14a, by means of which the gravitational aggregate can be placed on a floor 15a. The stand 14a is provided to receive a lever 2a, which is rotatably mounted about a bearing axis Ia. The lever 2a is mounted in a plane of movement perpendicular to a footprint 16a of the stator 14a. The plane of movement runs parallel to the drawing plane from FIG. 1.

The bearing axis Ia is connected by means of two ball bearings 17a, 18a on both sides with the stator 14a. It is arranged at a distance from the footprint 16a of the stator 14a. The lever 2a is arranged centrally on the bearing axis Ia. The He- at 2a is stored by the bearing axis Ia outside its center.

The lever 2a is intended to perform only a tilting movement. An angular range of the tilting movement can be limited by a stop on an angular range less than 180 degrees. The lever 2a is subdivided into two partial sections 19a, 20a with respect to the bearing axis 1a, or its attachment point for receiving the bearing axis 1a. The first part section 19a extends, starting from the bearing axis 1a, in the direction away from the contact surface 16a. The second subsection 20a extends from the bearing axis 1a in the direction of the footprint 16a. In a tilting movement of the lever 2a, the first portion 19a is always above a bearing plane 21a, which is defined by the bearing axis Ia and a plane parallel to the footprint 16a.

A crankshaft 22a, which is intended to receive a crank 4a, is arranged in the first subsection 19a of the lever 2a located above the bearing plane. The crankshaft 22a is disposed at a lever end of the first section 19a. It is supported on both sides by ball bearings 23a, 24a against the lever 2a.

The crank 4a is arranged centrally on the crankshaft 22a. The crank 4a is rotatably connected to the crankshaft 22a. On the crank 4a, a weight 5a is arranged at a distance from the crankshaft 22a. By means of the crankshaft 22a, the crank 4a is rotatably mounted about a rotation axis 3a. The crankshaft 22a allows a rotational movement of the crank 4a with the GE weight 5a. The rotational movement takes place in a plane parallel to the plane of movement of the lever 2a. The axis of rotation 3a of the crank 4a and the bearing axis 1a of the lever 2a are oriented parallel to one another and offset relative to one another.

The crankshaft 22a is passed through the ball bearings 23a, 24a on both sides. It has at its ends a first and a second receptacle 25a, 26a, each of which is intended to receive a respective spring 8a, 9a. The seats 25a, 26a extend in a direction parallel to the crank 4a and extend the crank 4a in a direction opposite to the weight 5a with respect to the crankshaft 22a.

The springs 8a, 9a are operatively connected at a first end to the receptacles 25a, 26a and at a second end to the lever 2a. By means of the receptacles 25a, 26a, the springs 8a, 9a are operatively connected to the crank 4a.

During a rotational movement of the crank 4a about the axis of rotation 3a defined by the crankshaft, the springs 8a, 9a interact with the crank 4a. The rotational movement is subdivided into two sections. The sections each comprise a half turn.

The sections are given by a position of the crank 4a relative to the lever 2a. In the first section, the crank 4a performs a rotational movement in which it moves from a position in which it is aligned with the lever 2a to a position parallel to the lever Lever 2a is arranged, moves. In the first part of the rotational movement, the springs 8a, 9a are stretched. In the second section, the crank 4a performs a rotational movement from the parallel position to the aligned position. In the second section, the springs 8a, 9a contract. The springs 8a, 9a are designed as tension springs. Basically, however, other types of springs, such as air springs or, with appropriate design, also compression springs and combinations of different types of spring conceivable.

The springs 8a, 9a and the crank 4a with the arranged on the crank 4a weight 5a are executed correspondingly. In an installation according to the invention of the gravitational aggregate, a gravitational force acts on the weight 5a during the rotational movement in the first section, by means of which the springs 8a, 9a are stretched. In the second section 19a, 20a, the springs 8a, 9a contract and counteract the gravitational force. The gravitational force and a spring force of the springs 8a, 9a compensate each other. The springs 8a, 9a are part of a gravitational compensation unit 7a, which compensates the gravitational force acting on the crank 4a with the weight 5a. The crank 4a and the weight 5a fixed to the crank 4a are balanced by the springs 8a, 9a.

By the rotary rotational movement of the crank 4a with the weight 5a, a position of a center of gravity of the crank 4a with the weight 5a shifts. Since a maximum horizontal distance between the position of the center of gravity and the crankshaft 22a is greater than a horizontal distance between the axis of rotation 3a of the crankshaft 4a and the bearing axis Ia of the lever 2a, the center of gravity moves in the horizontal direction over the bearing axis 2a during the rotational movement of the crank 4a and the lever 2a is subjected to a force which tilt it from one position to the other leaves. The tilting movement of the lever 2a is excited by means of the crank 4a. A force that drives the lever is provided by the weight 5a.

In order to set the crank 4a in the rotational movement and to maintain the rotational movement of the crank 4a, a motor 6a is arranged on the lever 2a. The engine is designed as an electric motor. By means of the motor 6a, the crankshaft 22a is driven, whereby the crank 4a is driven in the rotational movement. The crankshaft 22a is driven by means of a belt 27a and a pulley pair 28a. A smaller pulley of the pulley pair 28a is rotatably connected to the crankshaft 22a. A larger pulley of the pulley pair 28a can be driven by means of the motor 6a. By means of the motor 6a only the crank 4a is driven.

In a starting operation, the crank 4a with the weight 5a is manually moved to a start position. In the starting position, the springs 8a, 9a are in a relaxed state. The weight 5a has a maximum height.

When the crank 4a is released, it makes a rotational movement about the rotation axis 3a due to the gravitational force, thereby driving the crankshaft 22a. By the rotational movement of the crank 4a, the lever 2a is placed in the tilting movement. This tilting movement is a swinging movement and has a kinetic energy that can be used. The kinetic energy can be tapped either from the upper or lower part of the lever 2a. For utilization and in particular for conversion into a rotational movement, various methods are already known, such as, for example, mechanical, hydraulic, pneumatic and / or electromechanical methods.

Since the weight 5a and the crank 4a are balanced by means of the springs 8a, 9a, a strength of the motor 6a used is independent of the crank 4a and the weight 5a. An energy introduced by the motor 6a is used to maintain the rotational movement of the crank 4a. The tapped off from the tilting movement of the lever 2a energy is independent of a torque of the motor 6a. By means of the motor 6a, a speed of the crank 4a can be adjusted.

The kinetic energy of the lever 2a depends in particular on a length of the crank 4a, a size of the weight 5a and a length of the second portion 20a of the lever 2a. The maximum usable kinetic energy can be increased in particular if

the crank 4a is extended with the weight 5a, the springs 8a, 9a are reinforced,

the weight 5a on the crank 4a is increased,

- A lever length of the lever 2a is extended and / or

- Reduction wheels are used to increase a rotational speed of the crank, which also increases a frequency of the tilting movement of the lever 2a. The height of a tangible kinetic energy depends on which point of the lever 2a it is taken.

In order to increase the mode of action of the gravitational aggregate, the weight 5a has an additional balancing weight. By means of the balancing weight, a moment of inertia of a torque of the crankshaft 22a is increased. This additional balance weight leads to a balance, which is compensated by means of the motor 6a. This means that the balance weight must not exceed an engine power of the motor 6a.

In the figures 3 to 17 further embodiments of the invention are shown. In order to distinguish the exemplary embodiments, the letter a in the reference symbols of the exemplary embodiment in FIGS. 1 and 2 is replaced by the letters b to j in the reference symbols of the exemplary embodiments in FIGS. 3 to 17. The following description is essentially limited to the differences from the exemplary embodiment in FIGS. 1 and 2, wherein reference can be made to the description of the exemplary embodiment in FIGS. 1 and 2 with regard to components, features and functions that remain the same.

FIGS. 3 and 4 show an embodiment of a gravitational aggregate which, in contrast to the exemplary embodiment in FIGS. 1 and 2, has an altered gravitational compensation unit 7b. For a description of a function of the gravitational aggregate, reference may be made to the description of the embodiment in FIGS. 1 and 2. The gravitational compensation unit 7b has two flywheel masses 10b, 11b, which support a rotational movement of a crank 4b. The flywheels 10b, 11b are designed as flywheels, which are arranged on a lever 2b, on which the crank 4b is mounted. The first flywheel 10b is connected to a motor βb by means of a belt 27b. By means of the belt 27b and a first pair of pulleys 28b, a reduction is provided which converts a high speed of the motor 6b into a low speed of the flywheel 10b. The flywheel 10b is connected via a second pulley pair 30b and a second belt 29b with the flywheel IIb. Also, the second pulley pair 30b provides a reduction. The second flywheel IIb is connected to the crank 4b via a third pair of pulleys 32b and a third belt 31b. Also, the third pulley pair 32b provides a reduction.

The two flywheel masses 10b, 11b have the same weight and are arranged at the same distance from a bearing axis 1b of the lever 2b. As a result, the lever 2b is balanced and is moved only by the crank 4b when it makes a rotary motion.

Further, the crank 4b is balanced by means of a spring 8b connected to the crankshaft 22b and the lever 2b. The spring 8b is arranged analogously to the embodiment in Figures 1 and 2.

FIG. 5 shows a further embodiment of a gravitational aggregate according to the invention. The gravitational aggregate is ana- log executed in the embodiment in Figures 1 and 2.

In contrast to Figure 1, it has a Bewegungsumwandlungs- unit 13c, which is intended to tap a tilting movement of a lever 2c and convert it into a rotational movement.

The motion conversion unit 13c has two freewheel units 33c, 34c, which are connected in opposite directions. By means of the first freewheel unit 33c, a first direction of the tilting movement is tapped. By means of the second freewheel unit 34c, a second direction of the tilting movement is tapped.

The freewheel units 33c, 34c are connected to the lever 2c by means of a belt 35c. The belt 35c wraps around drive units of the two freewheel units 33c, 34c. In a region between the free-wheel units 33c, 34c, the belt 35c is coupled to the lever 2c. Two ends of the belt 35c are connected by means of two springs 36c, 37c to a stator 14c of the gravitational aggregate. By means of the springs 36c, 37c, the belt 35c can follow a tilting movement of the lever 2c.

The freewheel units 33c, 34c are each connected to a pulley 38c, 39c on the output side. By means of a belt 40c, the pulleys 38c, 39c are coupled to each other for rotational movement. By means of the belt 40c and the pulleys 38c, 39c, a high-lift is provided. A rotational movement of the pulleys 38c, 39c is transmitted to an attachment member 41c. The connection element 41c is advantageously connected to a dynamo unit 42c. By means of the dynamo unit 42c, a particularly advantageous utilization of kinetic energy of the lever 2c is possible.

FIG. 6 shows the gravitational aggregate from FIG. 5 in a gravitational aggregate assembly with a plurality of gravitational aggregates. To better distinguish the individual gravitational aggregates within the gravitational aggregate assembly, the components of other gravitational aggregates are characterized by different, elevated Roman numerals. Components of a gravitational aggregate are here and below marked with the same Roman numerals. Components of different gravitational aggregates with the same function are identified by the same reference numerals, and with respect to components that remain the same, reference should be made to the description of the gravitational aggregate with reference symbols without additional identification.

The gravitational aggregate network increases the usable total energy. Each gravitational aggregate has its own motion conversion unit 13c, 13c ¹ , 13c ¹¹ , 13c ¹¹¹ . The gravitational aggregates are connected to each other, in each of the same direction running connection elements 41c, 41c ¹ , 41c ¹¹ , 41c ^{111 of} the motion conversion units 13c, 13c ¹ , 13c ¹¹ , 13c ¹¹¹ are rotatably connected to each other.

Figure 7 shows an embodiment in which a tilting movement is realized by means of a lever 2d, which is moved by water force and gravitational force. A crank 4d is formed integrally with the lever 2d. A weight 5d, which is arranged on the lever 2d, or the crank 4d, is designed as a float. The embodiment further comprises a motion conversion unit 13d, by means of which a movement of the lever 2d is tapped and converted into a rotary movement. The motion conversion unit 13d is analogous to the embodiment in FIGS. 5 and 6.

FIG. 8 shows an exemplary embodiment of a gravitation aggregate with a modified motion conversion unit 13e. The motion conversion unit 13e has two belts 35e, 40e connected to a lever 2e of the gravitational aggregate. By means of the motion conversion unit 13e, a tilting movement of the lever 2e is converted into a rotational movement. The belts 35e, 40e are each provided with a spring

3e, 37e, which allows movement of the belts 35e, 40e. Further, each belt 35e, 40e is connected to a one-way unit 33e, 34e which picks up the movement of the corresponding belt 35, 40e in a reverse direction and converts it into a rotary motion.

The movement tapped by the freewheel units 33e, 34e is transmitted to a connection element 4e. By opposing the freewheel units 33e, 34 by means of the belts 35, 40e, both directions of the tilting movement of the lever 2e are tapped. The freewheel units 33e, 34e are each connected to the connecting element 4ee via a belt 43e, 44e.

The attachment element 41e is connected via a belt 27e to a crank 4e of the gravitational aggregate. This will a kinetic energy of the lever 2e again supplied to the crank 4e. Further, the attachment member 41e is connected to a dynamo unit 42e by means of the belt 27e.

FIG. 9 shows an alternative embodiment of a gravitational aggregate. The gravitational aggregate has a gravitational compensation unit 7f with two flywheel masses 10f, Hf designed as flywheels, which are rotatably mounted on a stator 14f of the gravitational aggregate.

The flywheel masses 10f, Hf are in each case operatively connected to a crank 4f of the gravitational aggregate by means of two belts 27f, 29f, 31f, 35f, which form a high drive. By the flywheel masses 10f, Hf a kinetic energy of the crank 4f is temporarily stored. If necessary, this kinetic energy can be picked up by the crank 4f. By means of the centrifugal masses 10f, Hf, a rotational movement of the crank 4f in a second partial section, in which a gravitational force counteracts the rotational movement of the crank 4f, is supported.

In addition to the flywheels 10f, Hf, the gravitational compensation unit 13f has two springs 8f, 9f which assist the rotational movement of the crank 4f. By means of the springs 8f, 9f, the crank 4f is largely balanced.

FIG. 10 shows the gravitational aggregate in a gravitational aggregate composite with two further, analogously configured gravitational aggregates. The gravitational aggregates of the gravitational aggregate composite are operatively connected to each other, in the flywheel masses 10f, Hf, 1Of ¹ , Hf ¹ , 1Of ¹¹ , Hf ¹¹ the gravitational aggregates rotatably connected to each other are. The centrifugal masses Hf, 1Of ¹ , Hf ¹ , 1Of ¹¹ , which are arranged between two gravitational aggregates, are embodied in one piece for the adjacent gravitational aggregates. Further, all cranks 4f, 4f ^I , 4f ^IJ the gravitational aggregates are rotatably connected to each other.

FIG. 11 shows a composite of two gravitational aggregates, which are operatively connected to one another by means of a pneumatic unit 45g.

The first gravitational aggregate is designed analogously to one of the preceding exemplary embodiments. A tilting movement of a lever 2g of the gravitational aggregate is tapped off by means of two pneumatic cylinders 46g, 47g of the pneumatic unit 45g. By means of the pneumatic cylinders 46g, 47g, an accumulator 54g is filled, which is provided for driving an alternative movement conversion unit 13g. The motion conversion unit 13g has two flywheel masses 10g, Hg. The centrifugal masses 10g, Hg are rotatably mounted about a common axis of rotation 55g. The rotation axis 55g is disposed between the two flywheel masses 10g, Hg. With respect to the rotation axis 55g, the flywheel masses 10g, Hg are disposed opposite to each other. The centrifugal masses 10g, Hg are displaceable by means of a pneumatic cylinder 56g along an axis 57g. The axis 57g is disposed perpendicular to the rotation axis 55g and intersects the rotation axis 55g.

The flywheel masses 10g, Hg are shifted as a function of a phase position of the flywheel masses 10g, Hg. The moving unit has a control unit 58g which is dependent of the phase position of the flywheel masses 10g, 11g the pneumatic cylinder 56g drives. The control unit 58g is designed mechanically and integrated into a rotary joint of the rotation axis 55g. In this case, the control unit 58g is provided to displace the flywheel masses 10g, 11g by means of the pneumatic cylinder 56g in such a way that the flywheel mass 10g, 11g, which performs a downward movement, has a greater distance from the axis of rotation 55g than the flywheel mass 10g, 11g, which has a Upward movement.

In a further, unspecified embodiment, it is also possible in principle to control an engine of a second, identical gravitational aggregate by means of the first gravitational aggregate. A usable kinetic energy of the first gravitational aggregate is then used to drive a crank of the second gravitational aggregate.

The crank of the second gravitational aggregate has a weight that is greater than a weight 5 g of a crank 4 g of the first gravitational aggregate. As a result, by means of the second crank, a tilting movement is generated, which includes a higher kinetic energy, whereby a larger amount of energy can be tapped on a lever of the second gravitational aggregate than on the lever 2g of the first gravitational aggregate.

FIG. 12 shows an exemplary embodiment of a gravitational aggregate which has an alternative embodiment of a gravitational compensation unit 7h. The gravitational unit has a crank 4h with a weight that is rotatably mounted on a lever 2h by means of a crankshaft 22h. The crankshaft 22h has a receptacle 25h, by means of which a further weight 12h is operatively connected to the crank 4h. By means of the crankshaft 22h and the receptacle 25h, a rotary movement of the crank 4h is converted into a linear movement, which is transmitted to the further weight 12h. The linear movement of the additional weight 12h is counter to the rotational movement of the crank 4h, on which a weight 5h is arranged. By means of the receptacle 25h and the weight 12h, a force is thus provided by which the crank 4h is balanced.

FIG. 13 and FIG. 14 show plan views of a further embodiment of a gravitational aggregate. The gravitational aggregate has a crank 4i, which is rotatably mounted by means of a crankshaft 22i. By means of the crankshaft 22i, the crank 4i is mounted against a carriage 48i, which is movable along a horizontal axis of movement. The carriage 38i is movably mounted to a stand 14i by means of a rail system 49i.

The crank 4i is operatively connected by means of a receptacle 25i with a spring 8i, which is designed as a gravitational compensation unit 7i. If the crank 4i is set in a rotational movement, a gravitational force acting on the crank 4i is compensated by the spring 8i. Due to the rotational movement of the crank 4i, a force acting on the carriage 48i causes the carriage 48i to oscillate along its horizontal axis of movement. The swinging motion is picked up by a motion conversion unit 13i and converted into a rotary motion. An attachment member 4i of the motion conversion unit 13i is connected to a dynamo unit 42i which converts the rotational motion into electrical energy.

FIG. 15 shows a combination of gravitational aggregates from the gravitational aggregate shown in FIG. 13 and three further analogous gravitational aggregates. Carriages 481 ¹ , 48i ^{i: E of} the further gravitational aggregates are arranged together with the carriage 48i of the first gravitational aggregate on the rail system 49i. All carriages 48i, 481 ¹ , 48i ^I3: are fixedly connected together for movement along the horizontal axis of movement.

Furthermore, all cranks 4i, 41 ¹ , 4i. ^iτ of gravity aggregates by means of a belt 27i rotatably connected to each other. By the belt 27i, the cranks 4i, 4i ^x , 4i ^{IΣ have} a synchronized movement through which a synchronized force acts on the fixedly coupled carriages 48i, 48i *, 48i ^XI .

To the force and thus of the movement of the carriages 48i, 4Si ^1, 48i ^I3: exploit recoverable energy advantageous, the gravitational aggregate composite to a further movement converting unit ISi ^1, by means of which a swinging motion of the carriage 48i, 48i ^x, 48i ^XI in a rotational movement converted and converted into electrical energy.

In the figures 16 and 17 is an embodiment of a

Gravity aggregate composite shown that particularly advantageous is liable, as it allows a continuous rotational movement.

The gravitational aggregate compound has eight gravitation aggregates. Each of the gravitational aggregates has a lever

2j, 2j ^I -2j ^VI1 , which are rotatable about a common storage item Ij. On each lever 2j, 2j ^I -2j ^VI1 is ^disposed a crank 4j, 4J ¹ - 4j ^VI1 having a weight 5j, 5j ^x -5j ^VI1 which are rotatable about axes of rotation 3j, 3J ¹ -3j ^VΪI parallel to the bearing axis Ij.

A gravitational force acting on the cranks 4j, 4j ^I -4j ^VI1 is compensated by means of gravitational compensation units 7j, 7j ^I -7j ^VI1 . The gravitational compensation units 7j, 7j ^I -7j ^VI1 each have a spring 8j, 8j ^I -8j ^VI1 , which are connected by means of receptacles 25j, 25j ^I -25j ^VI1 with the corresponding cranks 4j, 4j ⁱ _4jvn. The recordings 25j, 25j ^I -25j VI1 ^enclose with the cranks 4j, 4j ^J -4j ^VI1 an angle of about 135 degrees.

A rotational movement of the levers 2j, 2j ^I -2j ^VI1 is subdivided into two sections. The two sections are the same size and each comprise a rotation angle range of 180 degrees.

In a first subsection, the weights 5j, 5j ^Σ -5j ^{VI1 are} unguided. Due to a centrifugal force, the weights 5j, 5J ¹ -Sj ⁷¹¹ strive radially outward and orient themselves in the radial direction along an extension of the cranks 4j, 4j ^x -4j ^VI1 . An orientation of the cranks 4j, 4j ^x -4j ^VI1 in this direction can be assisted by means of motors 6j, 6j ^I -6j ^VI1 . The fashion 6j, 6j ^x -6j ^VI1 are ^disposed on the respective levers 2j, 2j ¹ -2j ^VI1 , and operatively ^connected to the corresponding cranks 4j, 4j ^x -4j ^VI1 via a belt 27j, 27j ^I -27j ^VI1 .

In a second subsection, the weights 5j, 5j ^I -5j ^{VI1 are} connected by a guide rail 5Oj, which is designed jointly for all gravitational aggregates. The guide rail 5Oj guides the weights 5j, 5j ^I -5j ^VI1 in the radial direction. In a first Teilbereicht comprising approximately 135 degrees, the weights 5j, 5j ^I -5j ^VI1 are guided radially inwardly with respect to the lever 2j, 2j ^z _2j ^VI1 . In a second subregion of the second subsection, the weights 5j, 5J ¹ - 5j ^{VI1 are guided} radially outward. The movement of the weights 5j, 5j ^I -5j ^VI1 is thereby ^assisted by the motors 6j, 6j ^I -6j ^VI1 .

Due to the different radial positions in the two subsections of the rotational movement, a net force acting in the gravitational aggregate compound acts in one direction of rotation

Rotational motion determined. The direction of rotation is directed in Figure 15 counterclockwise.

FIG. 18 shows an exemplary embodiment of a gravitation unit with a crank 4k, which is provided for a pitch circle movement about a rotation axis 3k. The crank 4k is rotatably mounted to a lever 2k. The lever 2k is arranged on a stand 14k and designed to perform a tilting movement about a bearing axis Ik. The tilting movement of the lever 2k is limited by two stops which are connected to the stand 14k. The crank 4k has a weight 5k. A gravitational force acting on the crank 4k is balanced by means of a gravitational compensation unit 7k. The gravitational compensation unit 7k has a spring 8k, which is operatively connected via a receptacle 25k and a crankshaft 22k with the crank 4k. The recording 25k closes with the crank 4k an angle of about 135 degrees.

To drive the crank 4k, the gravitational unit has a motor 6k, which is arranged on the lever 2k. The engine 6k is connected to the crankshaft 22k by means of a belt 27k. The motor 6k is formed as an electric motor. It generates an alternating torque, which is used to drive the crank 4k.

The crank 4k is arranged in a partial section 19k of the lever. The rotation axis 3k is parallel to the bearing axis Ik. The rotation axis 3k is arranged offset to the bearing axis Ik. Further, the rotation axis 3k is arranged offset to a direction of extension of a portion 20k of the lever.

The lever 2k has a limiting unit 51k, which restricts a rotational movement of the crank 4k to the pitch circle movement. The limiting unit has two stops 52k,

53k, which limit the pitch circle movement to about 90 degrees. In principle, however, a limitation to other angular ranges, such as 180 degrees, conceivable.

During the pitch circle movement of the crank 4k, a center of gravity of the crank 4k is moved over the bearing axis Ik, whereby on the lever 2k acts a force that stimulates the tilting movement. By reversing the direction of the pitch circle movement by means of the stops 52k, 53k, an additional force acting on the lever 2k is applied to a kinetic energy of the tilting movement.

The kinetic energy of the tilting movement is tapped off by means of a motion conversion unit 13k which has only one free-wheeling unit 33k. The kinetic energy is used to drive a dynamo unit 42k.
