The BBÖ VT 30 was an internal combustion engine operated by the Austrian Federal Railways (BBÖ). The prototype was created in 1924 in the main workshop in Floridsdorf ( Jedlesee ) by converting the former Viennese Stadtbahnwagen 35-327 of type C u .
History and technical data
After its delivery, the vehicle was assigned to the Mistelbach train conveyance station and used there until 1936. In 1938 it was taken over by the Deutsche Reichsbahn and designated as 721 with a second line-up. According to the inventory lists, the car was retired on July 11, 1939.
construction
The machine system, consisting of a four-cylinder four-stroke petrol engine and a mechanical three-speed gearbox, was placed on one of the two platforms of the donor vehicle . The drive motor developed 38 kW (52 hp) at a speed of 900 min −1 . He had a carburetor of Pallas and a magneto ignition by Bosch . The engine was started electrically and it could also be started with a removable hand crank.
A mechanical gearbox with three speeds of 8/20/40 km / h was driven from the engine via a foot-operated single- disk dry clutch . The individual gears were shifted by shifting the wheels. The reverse gear was also included in the mechanical transmission . From its exit, the axle closer to the drive motor was driven by a double roller chain . The cooling water tanks and their radiators were located on the car roof, as was the car's tank. This resulted in a natural gradient for the supply of fuel to the engine.
