PERFECCIONAMIENTOS EN LOS DISPOSITIVOS PARA EL RETROCESO CENTRAL HORIZONTAL DE UN ACOPLAMIENTO CENTRAL DE TOPES.

摘要

A device for returning a central buffer coupling horizontally to its mid-position, particularly for rail vehicles comprises a fixed housing with a coupling pin journalled in the housing and connected with one end of a coupling rod which is rotatable thereon. A guide plate which is pivotal on the coupling pin has respective opposite side faces having a pair of spaced side rollers along its side faces which engage against an oblique side surface of a ram which is slidable in the housing. The ram includes a side surface extending substantially perpendicular to the vertical axis of the coupling pin which glides along a surface of the housing and a biasing surface at right angles to the glide surface which forms a base for a device which biases the ram in directions toward the coupling pins. The biasing device may comprise springs or hydraulic fluid operated piston and cylinder combinations to act through the oblique surface of the ram and the rollers on the guide plate to return the central buffer coupling horizontally into its mid-position.
