Klien-Lindner axle
In the Klien - Lindner- hollow axle is a special driving axle for steam locomotives, which allows an improved sheet travel of the vehicles because of their radial adjustability. It was developed by engineers Ewald Heinrich Richard Klien and Robert Lindner of the Royal Saxon State Railways.
Design features
A hollow shaft supporting the wheels is centrally connected by way of a universal ball joint with the passing massive drive shaft. Both waves are also referred to in this context as inaccurate axes. The cardan joint consists of a hollow sphere in the split at this point the hollow shaft, a spherical sliding therein and a thickening of the solid axle seated in the ball member drive pin, which is guided in the hollow shaft into two axially extending sets. The drive torque is transferred from the outer frame mounted in the axis of the hollow axle of the wheel set, wherein an angular adjustment of the hollow shaft is possible. When deflected from the central position is formed upon rotation of the two axes a wobbling relative movement. The hollow shaft is axially displaceable in addition by the movable mounting of the hollow sphere of the universal joint forming the intermediate element. To limit the angular adjustability to the level of the tracks, so to prevent rolling movements of the locomotive, the hollow shaft is supported in addition usually at their ends extending horizontally scenes in a tiller frame.
Use
Despite the relatively simple construction, the Klien - Lindner- hollow axle proven in operational use is limited. The Klien - Lindner- hollow axles caused particularly rough running of the locomotives, which occasionally led to derailment. Then there was a higher maintenance cost, which is often out of proportion to the benefit of the lower flange and rail wear. To use the Klien - Lindner- hollow axle was therefore especially in applications where only a low driving speed was required, and thus the drawback of the troubled run did not matter. The most widely found on locomotives for narrow gauge railways, and because especially in forest and field paths.

Developments
The locomotive factory Orenstein & Koppel in Berlin has improved the design later. With an additional drawbar frame now supported the hollow shaft from the core axis. The inherent roll movements were thus prevented.
