As shown in the figures, the rail vehicle on a linkage 5, on which a first impeller 6, that is, a front impeller, and a second impeller 9, that is, a rear impeller, is arranged. About these wheels (6, 9), the weight of the vehicle is transmitted to the rolling surface portions of the rail part.

The rail part 2 has running surfaces (1, 3), whose normal direction is aligned transversely to the rail direction and roll on which rollers 13, so that the vehicle remains aligned with the rail, so the wheels (6, 9) on the provided rolling surface sections of the rail part roll.

The electric motor 7 is arranged on the vehicle linkage 5 together with the gear 8 driven by it. The output shaft of the transmission 8 drives the front wheel 9 at.

In a gradient region of the rail system, a chain is attached in sections, which is attached to a arranged in this section on the rail parts 2 sword section 12. In this case, a plastic layer 20 is disposed on the chain facing surface of the sword section 12, which is preferably provided as a coating on the sword section 12 and / or is designed as a composite part. The sword section 12 is made of metal. Likewise, the rail parts made of metal, in particular aluminum. Preferably, the rail parts are manufactured as extruded parts.

A slot waveguide 14 is attached to the respective rail part or integrally formed therewith, so that an antenna arranged on the vehicle projects into the slot area of the slot waveguide and during the movement electromagnetic waves can be coupled in or coupled out to create a data transmission.

The chain is composed of chain links 11, wherein at regular intervals chain link holding parts 10 are used as chain links, said chain link holding parts 10th
Run down extended and are bolted to the extension portion of the sword part 12.

Thus, the otherwise loose resting on the plastic layer 20 chain is attached to the rail part 2 on the sword part 12. For tensioning the chain, a respective chain tensioning means 4 is lowered at the respective chain end in the rail part.

Thus, the chain is fixed to the slope portion forming rail parts and / or fixed.

The roller 6 is in FIG. 5 shown in more detail and has a metallic hub portion 50 which is connected to two metal rims, on the outer periphery of each of which a rubber layer 30 is vulcanized or a plastic is encapsulated.

Likewise, the points in the Figures 3 and 4 Roller 9 shown in more detail on a hub portion 33, at the axial Endberiechen each a metal rim 31 is arranged and connected by screws 32. The metal rims 31 in turn have on their outer circumference each a rubber layer 30 vulcanized on or are encapsulated in accordance with plastic. The metal rims 31 are thus designed together with the rubber layer 30 as a composite part.

The hub portion 33 has a much smaller maximum outer diameter compared to the metal rims 31. Axially centered on the hub portion 33, a toothing is executed whose outer diameter is smaller than the outer diameter of the toothing 34th Thus engages the teeth, in particular running as sprocket teeth 34, in the slope section in the chain and prevents slipping or spinning the wheels.

The effect according to the invention of the maximum driving force increased by the positive support of the vehicle on the chain is advantageous not only for climbing or reverse driving through a slope but also for flat areas in which an increased driving force is required or the friction coefficient of the rollers 9 the associated Abrollbereichen is lowered, for example, iced Abrollbereichsabschnitten.

As in FIG. 6 shown, a chain tensioning means 4 is provided for tensioning the chain. In this case, the last of the chain links 11 is connected to the clamping element 61, which has a screw thread on its side facing away from the chain on which a nut is screw-connected. In this case, the clamping element 61 is guided through a recess of a block 63 and the nut 62 is arranged on the side facing away from the chain side of the block 63. A slippage of the nut 62 through the recess is not possible because the mother is too large for this. The block is connected to the rail part 2, in particular inserted from a direction transverse to the rail direction in a corresponding recess. By screwing and further screwing the nut 62, the chain tension is adjusted.

The chain tensioning means 4 has a deflection element 60, via which the chain is deflected towards the tensioning element 61.

The chain tensioning means 4 has the deflection element 60 are arranged in a recess of the rail part 2.
