A new wheelset design has been recently developed where independent wheels rotating on roller bearings are connected by a coaxial transmission shaft. The wheels-shaft connection can be done using a torque limiter, enabling a substantial reduction of the longitudinal forces and therefore a possible reduction of wear and RCF problems on both wheels and rails.

Abstract
A new wheelset design has been recently developed where independent wheels rotating on roller bearings are connected by a coaxial transmission shaft. The wheels-shaft connection can be done using a torque limiter, enabling a substantial reduction of the longitudinal forces and therefore a possible reduction of wear and RCF problems on both wheels and rails. This paper presents a study of the feasibility of a possible torque limiter design, crucial in the success of the aforementioned wheelset, by using a mission profile based on the mixed-conditions typical of the Sardinian backbone network. © Civil-Comp Press, 2016.File | Dimensione | Formato | |
