DE102007005546A1 - Model railway has break points in track section and/or in overhead line or live rail, between which electrically conducting connection between left-hand and right-hand running rail is created for addition of rotational voltage - Google Patents

Abstract

The model railway has break points in the track section and/or in the overhead line or live rail, and between these break points an electrically conducting connection between the left-hand and right-hand running rail, or between one running rail and the overhead line/live rail, is created for the purpose of addition of the rotational voltage. The track section and overhead line/live rail form a constructional unit, just one per stretch to be provided.

Description

1st assignment

These Invention is a toy in the field of electric model trains.

2. State of the art

So far are electric model railways with a power supply (transformer, Actuator) via supply lines or connected to batteries that drive the power to operate deliver. Unattractive wire connections on the other hand or limited battery capacity on the other hand are inevitable.

3. Objective

These Invention is an arrangement that drives the energy wirelessly (inductive) feeds to the track. The Electric energy flows from there by conventional means (wheels, pantographs) to the traction motor and drives the locomotive. Supply lines to the track will be dispensable, at the same time the energy supply by no energy storage limited. Furthermore, this system is to be made of series products (tracks, Vehicles, power supply) can be set up with few adjustments can.

4. Operating principle

The Electric energy is based on the principle of electromagnetic Induction transferred to the track. There it is available as AC voltage and becomes the traction motor fed.

in the In the simplest case, the arrangement consists of a circular track body, the passed through a toroidal core becomes (picture 1).

Of the Toroidal core is provided with a second winding (primary side) and to a AC voltage U2 connected. This creates a magnetic Induction B of the ring core, along the track circumference s a Circulating voltage U = ∮Bds generated, which in turn drives a current / in each rail s.

The Rails are at two opposite Places interrupted (AA 'and BB ') and the inner Rail becomes with the outside Rail electrically conductively connected (eg v = AB ', Figure 2). Thereby the current flow / in each rail is interrupted and the voltage U lets between the rails along the track circumference (Addition the circulating voltages). This arrangement represents a transformer whose secondary windings from two concentric, circular Rails exists. If you put a locomotive on the track, it starts Current flow - and the movement - via the drive motor: The electrical energy has been transmitted wirelessly to the locomotive.

It is irrelevant whether the circulation path through a rail, busbar or a catenary takes place, important alone is to go through it once to put the toroid so that a magnetic flux B is included, and then connect the end of one rail to the beginning of the other for adding the circulating voltages. Hence the terms Catenary and middle rail in the following as a catenary / conductor rail summarized.

Figure 3 shows an example of a circulation path (clockwise) and how the addition of the circulating voltage occurs. The points and distances illustrate the conductive connections:
Circulation 1 (clockwise): BAB 'it creates the voltage U along BB' to AA '

A Lok - after Feature 1 - drive now in the counterclockwise direction and is in the uninterrupted area AA 'to BB' of both bogies / sets with Power supplied. After passing the interruption BB 'occurs the front Bogie in de-energized area between CC 'to DD'; the rear bogie takes over uninterruptible the drive.

As soon as the rear bogie enters the de-energized area at CC ', the front bogie at AA 'again supplied with power and takes over uninterruptible the drive.

4. Vehicles

locomotives are for this arrangement suitable if they have 2 bogies or 2 wheelsets. The bogies are isolated from each other and lead the Electricity over Sliding contacts to the traction motor.

Per Bogie / wheelset, the AC voltage U is a bridge rectifier fed and then passed on to the DC traction motor.

at Vehicles with pantographs are powered by one Bogie / wheelset half and both pantographs (overhead line) and grinder (busbar).

The Geometry of bogies / wheelsets determined the lengths and the location of the tracks CD, C'D ', C''D' '.

1st feature:

The locomotive gets its drive energy via the wheels on the right and left in the bogie / wheelset (no Overhead line / busbar available), see Figure 3.1.1.

2nd feature:

The Lok derives its drive energy via the wheels on one side right in the bogie / wheelset and the overhead line / busbar, see Figure 3.1.2.

3rd feature:

The Lok derives its drive energy via the wheels on one side left in the bogie / wheelset and the overhead line / busbar, see Figure 3.1.3.

5. Power supply

The Supply provides a standard 12VAC Halogen lamp ballast in conjunction with a highly permeable ring core.

6 applications

The described arrangement in the scale 1: 220 (Z-lane) allows free Mobility of the track body and the train: it would be conceivable a track ring rotating on rollers with a train in opposite Direction of movement, only the toroid - as a tunnel piece - remaining in peace.
