Railway locomotive motor and transmission suspension - has coupling to main or bogie frame for straight or curved travel

摘要

The powered vehicle, esp. railway locomotive for high speed running, has bogie frames resiliently borne by wheel axles, vehicle frame on sprung mounting on these, one or more driven axles and parallel motor with firmly flanged, transmission gear and three-point suspension for motor and gear on vehicle frame. The motor- and gear-assembly (6, 10) is suspended from three pendulum mountings (7-9). One transversely aligned guide-rod (12) rigidly couples to the vehicle frame (13), and another (14) to the bogie frame (4). On straight track the first rod is coupled and the second released, and on curved track the first is released and the second coupled. construction is simple, with min. unsprung mass, and min. inertia moment affecting bogie mounting movement at high speeds.
