TKS® springs:

New progressive coil spring for railway vehicles

Higher requirements regarding speed and wheel set load of railway vehicles lead to the need of suspension springs with progressive spring characteristic. Conventional coil springs with progressive characteristic and constant wire diameter have some disadvantages which often make the use in railway vehicles more difficult or even prevent it.

The newly developed TKS^® spring with taper rolled wire cross section in the progressively acting coils avoids these disadvantages and therefore offers optimum features for the use as suspension spring in the running gears of railway vehicles.
