<b>Total Performance Evaluation of the Assist Steering System for Bolsterless Bogie</b>

Abstract

In order to decrease the lateral force generated in railway vehicles in curved sections, a simple steering system for bolsterless bogies has been developed. This bogie steering system does not adopt a complex bogie structure, and is equipped with a function to prevent reverse steering. The system is referred to as an "Assist steering system," It is composed of pneumatic actuators built into mono-links, a mechanical sensor to detect the bogie angle from the relative movement between the bogie and the car body, and a pneumatic valve that works according to the sensing device.
