Proposal of the Tram Car Bogie Conception with Advanced Suspension and Steering System

On the city railways, as a result of routine operation, significant track load take place. This is manifested by formation of track geometry deviation, rail heads wear and by the track clearance widening. Therefore the guiding forces in rail-wheel contact are increased and the situation is getting worse. Authors consider this situation firstly as a result of non-suitable bogie conception used by vehicles in operation, it means not as a poor quality of track building. This paper is focused to propose of a new tram car bogie conception, which take in to account specific conditions of the city railways, which for is the bogie intended. Presented bogie conception is characteristic by frame to wheelsets mounting by only three bearing boxes and by presence of mechanism for setting wheelsets to the radial position when passing track curves. This is a new, non-conventional solution, for which a number of patent applications have been filed. In this days, simulation analysis of vehicle ride equipped with proposed bogies are taken. Based on first obtained results, it is assumed multiple life extension of track and vehicle curve-passing resistance minimizing. Also significant reduction of ecological load to the environment caused by this transport system is expected.
