Luttermöller axle drive
The Luttermöller axle drive is a design that improves the cornering ability of steam locomotives .
Locomotives with several axles or wheel sets connected to one another by coupling rods are less able to negotiate tight curves. To remedy this, the director of the Orenstein & Koppel plant near Berlin , Dr. Luttermöller, the final drive named after him. Here, the outer of several drive wheel sets arranged one behind the other are not connected to crank pins with coupling rods on the outside of the wheel , but rather by gears arranged centrally on the axles of the wheel sets . The axes are the frame to a certain extent transversely to the center of the rail displaceably mounted, as well as the gears can move against each other. This results in lower-friction cornering.
The five-way coupled series 87 with two Luttermöller end axles was built for the Hamburg port railway with its tight curves . However, the 16 locomotives of this type were taken out of service again in 1954 because the vehicles tended to overheat at higher speeds and could therefore only be used in shunting services . A five-axle meter- gauge steam locomotive with the Luttermöller system for the narrow-gauge railway Walkenried – Braunlage / Tanne was procured from Orenstein & Koppel in 1928 by the private Südharz-Eisenbahn-Gesellschaft (SHE ). It proved itself so well on the winding route that in 1930 two Mallet locomotives from Henschel from 1925 were converted to the Luttermöller system (road numbers 56 and 57). To do this, Henschel had to obtain a license to use the Luttermöller drive from Orenstein & Koppel.
In the case of the DR series 84 , which was specially intended for the re-tracked Müglitztalbahn with its narrow radii , the two test locomotives delivered by Orenstein & Koppel in 1935 were also given the Luttermöller drive. However, the drive did not prove itself, the series delivery from BMAG from 1938 received the Schwartzkopff-Eckhardt steering frame used in the other two test locomotives delivered by BMAG .
The Luttermöller axle drive was also used for narrow-gauge railways on Java .
