Coupling rod

A coupling rod is a machine element in rail vehicles, which can be claimed by train or compressive forces. The application includes the following areas:

Locomotives

For locomotives with a common rod driving two or more sets of wheels, a coupling rod connecting the crank pin of the wheels to each other such that the driving force is transmitted to all the axes simultaneously. Apart from the so-called transmission locomotives and locomotives with Einzelachsantrieb via Steam engines at each Antriebsradsatz coupling rods were used in steam locomotives with several driven wheelsets always apply. The wheel sets are connected to each other via this known coupling axle (s).

In the first constructions of diesel and electric locomotives with rod drive the prime mover had either directly on a driving axle and from the latter on the coupling rods on the other (s) driving axle ( s) ( see, for example Deutz OMZ 122 R ) or on a dummy shaft, from which about ( driving and ) Kuppelstangen the driving axles are powered (eg in the series V 36, V 60 or e 63 ).

Kuppelstangen also found in some railcars ( eg different VT 137) use.

Connect of railway vehicles

A coupling rod called an auxiliary connection of railway vehicles in cases where the existing couplings can not be used. Similar function satisfies the tow bar of automobiles or other vehicles but it is used only in the event of an accident. For example, a coupling rod is used in the following cases:

• The connection of auxiliary vehicles with railroad car or trailer.
• The compound cart or dollies with a narrow gauge trolley or a -lok during transport normalspuriger car.
• When maneuvering of Tender senders that are separated from the steam locomotive and be attached to the locomotive side.

• Schienenfahrzeugtechnik
• Steam locomotive technology
