Definitions

  • the present disclosure is directed to couplers for railway cars, and, more particularly, to a device for horizontally centering a railway car coupler.
  • Railway vehicle cars include couplers for connecting adjacent cars to each other to form a train composition.
  • Each coupler is adapted to swing within a predetermined angular range in a horizontal direction to facilitate car coupling and movement on a curved track.
  • Adjoining car couplers must be aligned to be on-center with the longitudinal axis of the railway car during a car coupling procedure. Due to variations in sizes of the cars and the type of coupler installed on each car, there may exist significant horizontal offsets between adjacent couplers in the lateral direction of the railway car. Such horizontal offsets are further compounded when attempting to couple adjacent railway cars on a curved section of a railway track or while moving on the curved track.
  • Couplers utilize pneumatically or hydraulically assisted coupler centering devices capable of moving the car coupler within a predetermined angular range in a horizontal direction to facilitate mating with an adjoining car coupler. These devices often require auxiliary equipment, such as pumps, hoses, and valves, that is positioned on an underside of each railway car.
