Title
(EN) RAILROAD CAR COUPLING SYSTEM
(FR) SYSTÈME D'ACCOUPLEMENT DE WAGON
Abstract
(EN) A railroad car coupling system including a draft sill with front and rear stops, a coupler along with an energy management assembly for receiving and dissipating external forces experienced by the coupler. A yoke also forms part of the coupling system and is operably coupled to the coupler. The yoke includes top and bottom walls which each include two forward facing stops. A follower is mounted substantially between the top and bottom walls of the yoke for receiving forces experienced by the coupler. The follower is configured with two laterally spaced vertical extensions disposed toward opposed upper corners of the follower and two laterally spaced vertical extensions disposed toward opposed lower corners of the follower. Forward facing surfaces on the follower extensions are arranged in generally coplanar relationship relative to each other. Rearward facing surfaces on the follower extensions are arranged in generally coplanar relationship with each other and operably engage with the forward facing stops on the yoke to enhance the distribution of forces when the follower engages the front stops on the center sill when the coupling system is in a full draft condition.
(FR) La présente invention concerne un système d'accouplement de wagon comprenant un seuil de traction avec des butées avant et arrière, un dispositif d'accouplement avec un ensemble de gestion d'énergie pour recevoir et dissiper des forces externes subies par le dispositif d'accouplement. Une fourche fait également partie du système d'accouplement et est accouplée de manière fonctionnelle au dispositif d'accouplement. La fourche comprend des parois supérieure et inférieure qui comprennent chacune deux butées tournées vers l'avant. Un suiveur est monté sensiblement entre les parois supérieure et inférieure de la fourche pour recevoir des forces subies par le dispositif d'accouplement. Le suiveur est doté de deux extensions verticales espacées latéralement disposées vers des coins supérieurs opposés du suiveur et de deux extensions verticales espacées latéralement disposées vers des coins inférieurs opposés du suiveur. Des surfaces tournées vers l'avant sur les extensions de suiveur sont agencées dans une relation généralement coplanaire les unes par rapport aux autres. Des surfaces tournées vers l'arrière sur les extensions de suiveur sont agencées dans une relation généralement coplanaire les unes par rapport aux autres et viennent en prise de manière fonctionnelle avec les butées dirigées vers l'avant sur la fourche pour améliorer la distribution des forces lorsque le suiveur vient en prise avec les butées avant sur le seuil central lorsque le système d'accouplement est dans une condition de traction complète.
