In the known axle counting devices, electromagnets are connected via rail contacts, which are actuated by the pull axles, excited by lifting and pawls the tightening and falling movements of their anchors are transmitted to a climbing wheel. Through suitable contacts on this the desired monitoring options are given. Such bodies are not suitable for the different directions of travel of the wheel contact trigger different effects. To make them usable for this purpose, special auxiliary relays are required, who cause certain difficulties in the company and usually do not perform the task at hand completely meet.

The present invention relates to an axle counting device in which, instead of the lifting armature or the rotating armature to and fro, as it has also become known, a magnetic switch is used in which is the rotating anchor during one and the same direction of travel of the train in the same Direction rotates around, wherein several circularly arranged coils are provided and the armature is within this Coil rotates and with each progression from one coil to another or from a PoI tooth on the other hand, the counter is influenced. An anchor rotating continuously in the same direction is in other cases already become known, z. B. with display instruments, in which by remote reporting the fluid level is displayed at any location.

Axle counting by rolling a wheel into the area of the two wheel contacts are initiated, are immediately deleted when you roll back and are only completely after the second wheel contact has also been completely overrun.

In the drawing, a simple axle counting device is shown in Fig. 1, in which For example, when driving in one direction counters and when driving in the opposite direction Direction counts should be made.

The magnetic switch consists of the stator with the three field windings 1-1, 2-2, 3-3 and the rotating armature 4 without any special winding. The rotating armature 4 is through gear reduction 19, 20 coupled to the counting disk 5. The counting disk 5 carries a sliding contact piece 6, with a mating contact 7 fixed in the frame in the basic position the device closes the sliding contact via which the current of the monitoring magnet flows.

The field winding 3-3 of the magnetic switch

has a current flowing through it in the rest position. The anchor 4 is as a result in this Rest position 3-3 held. The field windings 1-1 and 2-2 are with the wheel contacts 9 and 10 in connection.

If you are driving in the direction of 9-10, wheel contact 9 will be the first closed by the wheel rolling over it, field ι-1 is excited and thereby the armature 4 Pulled into position 1-1, so moved in the sense of clockwise rotation by 60 °. Follows Now that the wheel contact 10 is driven over, field 2-2 is excited and thereby the anchor is pulled into position 2-2, while field 1-1 is de-energized, i.e. moved by a further 60 °. If the wheel contact 10 is now left by the wheel in the same direction of travel, will also field 2-2 de-energized again and armature 4 through the home position field 3-3 in its center line drawn. So it is back in its basic position, but at an angle of 180 ° twisted. The monitoring contact 6, 7 is due to the rotation of the coupled to the armature Counting disk 5 has been opened, and the monitoring magnet 8 has indicated this by falling off its armature. With more When driving in the same direction, the same process takes place every time, and that Contact piece 6 continues to move away

from 7.

When driving backwards in the opposite direction, the wheel contact takes place first 10 is driven on, the anchor turns to the left, as the field 2-2 is first excited and pulls the armature out of the basic position 3-3 in the opposite direction of rotation. After driving past the same number of axes as before in the other direction, must the contact piece 6 will be back in its comparison with 7, what the ' Monitoring magnet again by tightening its armature.

To the anchor 4 in the wheel contact drives without inhibition from the basic position to be able to pull out, can by a counter-winding -3 ° on field 3-3, which occurs simultaneously with the excitation of field windings 1-1 and 2-2 is switched on, the field 3-3 will be demagnetized.

In Fig. 2 an embodiment is shown in which two of the previously described magnetic switches c and d with their counting disks 17, 18 and wheel contacts 11, 12 and 13, 14 are brought into relation to one another in such a way that the sliding contact 15, 16 is opened, as soon as one of the two counting disks 17 and 18 is moved out of its basic position.

If the wheel contact pair 11, 12 first traveled on by a number of axes, the counting disk 17 moves with its Contact piece 15 by a corresponding piece out of the basic position, the contact 15, 16 is opened.

Then the wheel contact pair 13, 14 If the same number of axles are in the same direction of travel, the will move Counting disk 18 with its contact piece 16 by the same amount from its basic position out in the same sense of rotation until it is opposed to the contact piece 15 of the Counting disc 17. The monitoring contact is activated again, but in a different position of the two counting discs, closed. Only part of the run runs into the distance between the two wheel contact pairs retracted axles via the wheel contacts 13, 14 and the rest backwards via the wheel contacts 12, 11 out of the enclosed route, so the counting disk 17 with its contact piece 15 runs back accordingly, and the two contact pieces 15, 16 meet in a central position and give on this Place the surveillance sign. So by the meeting of 15 and 16 indicates that between the contact pairs 11, 12 and 13, 14 is located Route is free of train axles.
