induction generator known.

From DE 101 47 720 A1 a self-sufficient energy recovery system is known.

The invention is therefore based on the object to maintain safety-related functions of a rail system even in case of failure of the electrical supply.

According to the invention the object is achieved in the system according to claim 1 or 2 and in the system according to the features indicated in claim 14.

Important features of the invention in the system are that it has a first part and a second part, wherein the first part and the second part are arranged movable parallel to each other in a direction of movement, wherein the first part is a winding around a leg, in particular middle leg, a coil core, the first part having a guide, in particular a linear guide, and a movable parallel to the direction of movement, in particular linearly movable, arranged permanent magnet, wherein the permanent magnet of the guide, in particular in the direction of movement, guided and, in particular in the direction of movement front and rear, limited.

The advantage here is that the electrical energy regardless of the amount of

Speed of the two parts to each other is. The biasing is so slow or fast executable; however, regardless of the time used for biasing, the generated energy pulse is essentially similar. The energy of each pulse is also independent of the relative direction of movement to each other. In addition, the same energy pulse is available even with multiple passes in the same direction. The system according to the invention operates without wear and without contact. The energy coil is generated synchronously on both sides.

In an advantageous embodiment, the magnetization direction of the permanent magnet is aligned parallel to the direction of movement within the guide. The advantage here is that the permanent magnet of the first part repel on a magnetic field generated by the second part, in particular by a permanent magnet of the second part. Thus, the permanent magnet of the first part moves in the movement clearance provided to it from the guide to the boundaries in such a way that first of all a magnetic movement

Preload is built up and instantaneously degraded after exceeding an unstable position, the largest possible change of the magnetic flux flowing through the winding of the first part is effected during dismantling. This is achieved by the fact that

Movement of the permanent magnet is so large that at one position the north pole is arranged closer than the south pole to the leg and that is arranged at a different position of the south pole closer than the north pole to the leg.

In an advantageous embodiment, the permanent magnet has such a large

Movement play in the guide on that at a first position the north pole of the

Permanent magnet is arranged closer than the south pole of the permanent magnet to the leg and that is arranged at a second position of the south pole of the permanent magnet closer than the north pole of the permanent magnet to the leg. The advantage here is that the

Movement allows a reversal of the magnetic flux.

In an advantageous embodiment, the movement play of the permanent magnet in the guide is smaller than the length of the permanent magnet in the direction of movement. Is an advantage in that, when the permanent magnet stops, a bias voltage is built up in the magnetic field at the respective boundary. The mechanical work is done in the

Magnetic flux density stored and converted only when relaxing in electrical energy.

In an advantageous embodiment, a magnetic flux generated by the permanent magnet is passed through the leg of the spool core, wherein the direction of the magnetic flux in the leg is dependent on the position,

In particular, the linear position of the permanent magnet in the guide, in particular wherein the at a first position, in particular linear position, of the

Permanent magnet adjusting direction of the magnetic flux in the leg is directed opposite to the case of a second position, in particular linear position, the permanent magnet adjusting direction of the magnetic flux in the leg. The advantage here is that the magnetic flux change is triggered by the position change and thus a high voltage is triggered.

In an advantageous embodiment, in the first position, the permanent magnet abuts against a first boundary of the guide, and in the second position, the permanent magnet abuts the other boundary of the guide. The advantage here is that in attacks on a limit bias is further buildable.

In an advantageous embodiment, the second part has a second, in particular stationary, permanent magnet or the second part is mirror-symmetrical to the first part, wherein the magnetization direction of the permanent magnet of the second part parallel, in particular rectified parallel, aligned with the magnetization direction of the permanent magnet of the first part is. The advantage here is that when providing a stationary, so in particular fixedly arranged on a rail part, permanent magnet, the second part is particularly easy to assemble. In an advantageous embodiment, the first part is spaced from the second part. The advantage here is that an air gap between the two permanent magnets and thus the bias is contactless executable.

In an advantageous embodiment, the second part has a second winding around a second leg, in particular center leg, of a second coil core, the second part having a second guide, in particular a linear guide, the second permanent magnet being movable parallel to the direction of movement, in particular linearly movable, is arranged, wherein the second permanent magnet of the second guide, in particular in

Direction of movement, guided and, in particular in the direction of movement front and rear, is limited. The advantage here is that a synchronous pulse release is executable on both sides and thus on both sides a respective electronic circuit can be supplied.

In an advantageous embodiment, the magnetization direction of the second

Permanent magnets aligned parallel to the direction of movement within the second guide. The advantage here is that the permanent magnet of the second part is generated at one of the first part, in particular by a permanent magnet of the first part

Magnetic field, repel. Thus, the permanent magnet of the second part moves in the movement clearance provided by the guide up to the boundaries in such a way that initially a magnetic bias is built up and instantaneously degraded after an unstable position is exceeded, the largest possible change in the winding during disassembly the second part flowing through the magnetic flux is effected. This is achieved in that the movement play of the second permanent magnet is so large that at one position the north pole is arranged closer than the south pole to the leg of the coil core of the second part and that in another position the south pole closer than the north pole to the leg is arranged.

In an advantageous embodiment, a generated by the second permanent magnet

Magnetic flux passed through the leg of the second coil core, wherein the direction of the magnetic flux generated by the second permanent magnet in the second leg is dependent on the position, in particular linear position, of the second

Permanent magnet in the second guide, in particular wherein the at a first position, in particular linear position, of the second permanent magnet adjusting direction of the magnetic flux in the second leg is directed opposite to at a second position, in particular linear position, the second permanent magnet adjusting direction of the magnetic flux in the second Leg. The advantage here is that the movement of the second permanent magnet allows reversing the magnetic flux in the leg of the spool core of the second part.

In an advantageous embodiment, the second permanent magnet has such a large one

Movement in the second guide on that is arranged at a first position of the north pole of the second permanent magnet closer than the south pole of the second permanent magnet to the leg and that in a second position of the south pole of the second permanent magnet closer than the north pole of the second permanent magnet to the leg out is arranged. The advantage here is that the movement allows a reversal of the magnetic flux.

In an advantageous embodiment, the movement play of the second permanent magnet in the guide is smaller than the length of the second permanent magnet in the direction of movement. The advantage here is that at stop of the second permanent magnet to the respective boundary, a bias voltage is built up in the magnetic field. The work done mechanically is thus stored in the magnetic flux density and converted into electrical energy only when it is released.

In an advantageous embodiment, in the first position, the second permanent magnet abuts against a first boundary of the second guide, and in the second position, the second permanent magnet strikes against the other boundary of the second guide. The advantage here is that after attacks, the magnetic bias can be increased.

Important features of the system with movable on a rail part arranged rail vehicle, that the first part is arranged on the rail vehicle and the second part is arranged on the rail part. The advantage here is that security functions can be ensured even in case of failure of the electrical power supply.

Further advantages emerge from the subclaims. The invention is not limited to the combination of features of the claims. For the expert, further meaningful combination options of claims and / or individual arise

Claim features and / or features of the description and / or figures, in particular from the task and / or the task by comparison with the prior art task. The invention will now be explained in more detail with reference to schematic illustrations:

1 shows a longitudinal section through an inventive system for generating electrical energy, in particular generator, shown schematically.

FIGS. 2 to 5 show the sequence of a triggering of pulses when the two parts of the system move relative to one another in a first direction.

In FIG. 6 and FIG. 7, two different starting positions are shown, which are provided before the sequence according to FIG. 2 to FIG.

FIGS. 8 to 11 show the sequence of a triggering of a pulse when the two parts of the system move relative to one another in a first direction.

In FIG. 12 and FIG. 13, two different initial positions are shown, which are provided before the sequence according to FIG. 8 to FIG.

As shown in the figures, the system, in particular generator, two relatively linearly movable parts.

Thus, energy can be generated from both parts if they are moved linearly in parallel to each other. In this moving together of the parts permanent magnets are biased and induced in the sudden relaxation in respective windings 6 voltages with which an electronic circuit and / or a sensor powered and evaluated can.

For example, a railroad, in particular monorail, is equipped with the generator according to the invention. Here, the first part of the generator is arranged on the rail vehicle, the second part is arranged on a rail part of the rail track, in particular directly or indirectly. Thus, the second part is arranged stationary and the first part with the rail vehicle mitbewegbar. The first part and the second part are each carried out the same way. Thus, in case of failure of the electrical supply of the railroad on the rail vehicle, an electrical supply is provided and also stationary when the rail vehicle is moved manually or from another source of power.

Because of the movement, a magnetic bias of the permanent magnets of the two parts is generated against each other, which is suddenly relaxed when pushed further.

Thus, a data transmission between the rail vehicle and a stationary arranged electronic circuit is possible even in case of failure of the power supply.

This is particularly advantageous when driving through a switch so that it can be actuated even in the currentless case.

Each of the parts has a permanent magnet 1, which is guided linearly in a guide 2 in particular to the rail direction of the rail part. The guide 2 also acts as a boundary in both directions, ie in the direction of movement, in particular in the rail direction and counter to the direction of movement, in particular the rail direction.

As shown in FIG. 1, the direction of magnetization of the permanent magnet 1 of the first part is oriented counter to the relative direction of movement 4.

A coil core 7 designed as an E core carries a winding 6 around its middle leg.

As shown in Figure 1, the magnetic flux generated by the north pole of the permanent magnet 1 flows into the center leg of the spool core 7, via the yoke of the E core to in

Direction of movement forward outer leg of the E-core and from there to the south pole of the permanent magnet 1 back.

The mirror-symmetrically structured second part is moved relative to the first part to the right. Thus, the two south poles repel each other and the permanent magnet of the second part moves within the leadership of the second part to the right, to the stop on his leadership, so that the south pole of the permanent magnet of the second part as far away from the south pole of the permanent magnet 1 of the first Partly removed and as close to the north pole of the permanent magnet 1 of the first part. The permanent magnet 1 of the first part is pressed in a corresponding manner to the left, so in the direction of movement 4 front, limiting the guide 2.

In Figures 2 to 5, a biasing and subsequent relaxation of the permanent magnets of the two parts is shown as a sequence of successive states. It can be seen here that, in the case of the passage of FIG. 2 according to FIG. 3, the magnetic flux in FIG

Mittelschenke is reversed. Likewise, the magnetic flux is reversed in the

Movement of Figure 4 of Figure 5.

In the reversal of the magnetic flux thus takes place in each case a sudden strong change of the magnetic flux, which thus induces a voltage in the winding 6, which supplies a respective electronic circuit.

The inversion takes place synchronously in both parts.

As can be seen in FIG. 3, the two parts are moved past one another along a common linear axis. The permanent magnets align within their degree of freedom. Thus, the permanent magnet 1 of the first part is pushed to the right to the limit and the permanent magnet of the second part is pressed to the left to its limit. Thus, the permanent magnets are then at their respective stop. Depending on the speed of the movement from the state of Figure 2 to the state of Figure 3, a voltage in the winding 6 is induced.

The further movement now builds up a magnetic bias until the state of Figure 4 is reached. During this build-up of magnetic preload, mechanical work must be done while shifting the parts that are stored in the bias of the magnetic field.

After exceeding the unstable position with the maximum magnetic bias according to Figure 4, the state of Figure 5 is suddenly reached, wherein the permanent magnets repel each other and abut the respective oppositely disposed boundaries. At the same time, the magnetic flux direction reverses in the center leg, so that a voltage is induced in the winding 6, which has a high peak value due to the sudden rapid reversal of the magnetic field. The respective voltage pulse provided in this way supplies the respective electronic circuit.

Other starting positions are shown in FIG. 6 and FIG.

FIGS. 8 to 12 show the states corresponding to FIGS. 2 to 7 in the opposite direction of movement of the parts relative to one another.

The guide is designed in particular as a linear axis.

As shown in the figures, the second part with its housing 9 is fixed to the

Rail part connected and the first part is moved relative to the second part. Alternatively, the second part is arranged movable. In further embodiments of the invention, the second part is replaced by a permanently fixed to the rail part permanent magnet. The described

Mechanism of action remains unchanged for the first part.
