Elastic articulation of a central buffer coupling for rail vehicles

摘要

To obtain a defined reset for horizontal articulations for an elastic articulation of a central buffer coupling, if at least one elastic ring is used, the inner part of the housing as well as the drawbar have the greater axis of their cross-section in the vertical in the installed position. The coupling which is secured on the vehicle and a drawbar which traverses the housing are supported by a ring of rubber, plastic or similar resilient material which is prestressed normal to the coupling axle of the coupling and arranged between the housing and the drawbar. The drawbar and a side of the housing have peripheral cams directed toward each other. The housing and the drawbar have an oval cross-section and the rings are spaced by cams formed on the drawbar and portions of the housing, the ring and the housing and the drawbar have a major axis of their cross-section extending along the vertical in their installed position.
