An Approach to Railbus Transmission Engineering
Published January 01, 1982 by Institution of Mechanical Engineers in United Kingdom
Epicyclic change speed transmissions have been engineered successfully for diesel powered public service vehicles and railcars for fifty years. The transmission design philosophy for both transport sectors run in parallel although the need to meet different operational requirements has understandably caused deviations from a totally common approach to product evolution. This paper considers the level of design integration appropriate for the two sectors and offers technical justification where there are major differences. The relevance of the major factors considered are given credence by reference to the operational experience gained from the latest prototype bi-directional gearboxes and final drive units designed and developed specifically to meet the requirements of the next generation of rail vehicle. An extrapolation into the future points the way forward through fully integrated power train engineering.
