Abstract

To further increase the speed of railway vehicles running on existing narrow-gauge track, we developed a new tilting system that enables the car body to tilt at a larger angle than conventional tilting trains. The system coordinates tilting beams and a controlled air spring height, thus reducing losses in wheel-load and avoiding lateral displacement of the car body caused by the larger tilting angle. This paper reports the features of the hybrid tilting system, the control method applicable to such tilting and the results of the bench tests carried out.
