Abstract

The invention relates to a system comprising rail sections, between which a switching member is disposed, a drive device for driving the switching member during the changing of the switchblade position, wherein the switching member is operated in an elastic deformation region during the changing of the switchblade position.

Description

The invention relates to a soft plant.

It is known that switch pieces are moved and / or rotated when changing the points position in different spatial positions.

From the US 3,093,090 A a Schlenenstück arranged between two points pieces is known.

From DE 10 68 286 B, a switch is also known.

The invention is therefore based on the object to enable easier production in soft systems.

According to the invention, the object in the system according to the in claim 1.

Important features of the invention in the system are that it comprises rail pieces, between which a switch piece is arranged,

a drive device is provided for driving the switch piece when changing the switch position,
wherein the switch piece is operated when changing the switch position in the elastic deformation range.

The advantage here is that no complicated mechanical displacement and / or rotation devices are necessary but a direct connection of the points piece is made possible with a linear drive.

In an advantageous embodiment, the drive device is a linear drive. The advantage here is that a cost simple drive is used.

In an advantageous embodiment, the switch piece is made of copper or aluminum, in particular continuous casting. The advantage here is that soft material is used and thus a simple adjustment is possible.

In an advantageous embodiment, the points piece in two or more points settings can be brought. The advantage here is that the elastic range is so large for long turnouts that even more than two points settings are possible.

In an advantageous embodiment, a first end of the switch piece is unchanged and the other end arranged variable when changing the switch position.
Advantageously, therefore, no special bearing or a corresponding guide for the turnout is necessary.

In an advantageous embodiment, a primary conductor is laid along the turnout piece, which is also mitverformt elastic. The advantage here is that the electrical supply is tracked along with the rail the car and the supply is done without contact.

In an advantageous embodiment, a leaky-waveguide or hollow-waveguide primary conductor is laid along the turnout piece for data transmission between a carriage which can be moved on the rails and the stationary part of the installation, which is likewise deformed elastically when changing the points position. The advantage here is that even the data transmission line is tracked.

In an advantageous embodiment, a movable on the rails car from the laid along the route primary conductor is supplied by a medium-frequency current is impressed, in particular with a frequency between 10 and 500kHz, wherein the carriage is provided with a inductively coupled to the secondary secondary coil, the a capacitor is connected in parallel or in series, wherein the associated resonant frequency of the frequency of the impressed current substantially corresponds. The advantage here is that even with changes in distance between the primary conductor and secondary coil, a high efficiency in the contactless energy transfer to the car can be achieved.

In an advantageous embodiment, the carriage comprises a rotatably mounted pole wheel, on the circumference of permanent magnets are arranged, which is in operative connection with a metallic rail part, in particular of aluminum as eddy current drive. The advantage here is that means of elastically executed deformation a low-jerk or jerk-free transition into the switch area and thus the eddy current drive, which has a high speed and thus a high angular momentum transverse to the route, only low evasion torques when entering the switch area generated.

The advantage here is that in contrast to the prior art, a mere deformation is used to change the point position. Thus, a linear drive in the vicinity of the second end of the turnout piece is advantageously mounted to realize small amounts of force in the adjustment.

Preferably, the switch piece is made of continuous casting.

LIST OF REFERENCE NUMBERS

1. 1 straight rail section
2. 2 points piece
3. 3 support device
4. 4 treads for wheels

The invention will now be explained in more detail with reference to figures:

In the FIG. 1 the detail of a system according to the invention is shown in plan view.

In the FIG. 2a the soft is shown in a first turnout position. In the FIG. 2b in the other direction:

Between the straight rail sections 1, which are mounted on support devices 3, a points piece 2 is arranged, which is arranged aligned at its first end provided in the rail direction in such a way with the straight rail piece 1 that the wheels of the trolley run over the interface without jerk.

The running surfaces 4 for wheels of the vehicle are thus essentially smooth over into the running surfaces of the straight rail section and vice versa.

The switch is now designed such that the switch piece is elastically deformed when changing the first to the second switch position as in FIG. 2a and 2 B seen.

To change the switch position, a linear drive is used whose force is indicated in the figures with F.

Thus, the switch piece 2 remains in position at its first end, while its second end is adjusted and forms a smooth transition to either the left or second points outlet.

Along the rail section, a primary conductor is laid, from which the car with its drive and its consumers are supplied without contact. For this purpose, the carriage has a secondary inductively coupled to the primary conductor secondary coil, which is connected in such a way with a capacity in series or in parallel, that the associated resonant frequency with the frequency of an impressed in the primary conductor miltelfrequenten current substantially matches.

The primary conductor is clipped into a plastic profile, which is clipped into the lower area, in particular below the running surfaces, of the rail sections.

Schlenen pieces and turnouts themselves, however, are preferably made of aluminum or copper. They are designed so long that the adjustment takes place from the first switch position to the second within the elastic range and does not affect the inelastic region.
