ABSTRACT:
A railway vehicle, in particular a locomotive, has three or more trucks with the bolsters of each swivelly supported on the respective truck frames and having means for transmitting longitudinal traction and braking forces to the body underframe. The truck bolsters mount upright body-support spring devices which are yieldable in shear transversely of the locomotive to permit sufficient limited lateral movement of the body with respect to the trucks to prevent the full force of lateral blows and shocks received by the wheels from being communicated to the body and for preventing the momentum of the body from acting with its full lateral force on the truck wheels and rails. The upright springs of the end trucks support the underframe directly while the upright springs of the intermediate truck or trucks support a superbolster which is movable transversely of the locomotive underframe a substantial distance in addition to the lateral deflection of the upright springs to accommodate the additional lateral movement or excursion of the intermediate truck or trucks with respect to the underframe required during operation on curved track.
