Curving Performance Evaluation of EEF Bogie with Inclined Wheel Axles Using Scale Model Vehicle

Part of the Lecture Notes in Mechanical Engineering book series (LNME)

Abstract

The EEF bogie proposed by Frederich realizes excellent curving performance making use of gravity restoring forces generated by the tread gradient of independently rotating wheels. However, the bogie gives rise to a kind of hunting motion due to slight longitudinal creep forces of wheels as the vehicle running speed increases. In the previous study, an effective modification of the EEF bogie which solves the hunting motion is mentioned. The solution is to incline both wheel axles while using nearly cylindrical tread. In this paper, the EEF bogie with inclined wheel axles is designed while performing running experiment with scale model vehicle on a sharp curve. From the result of experiment, the proposed bogie has excellent curving performance in tight curve.
