A friction-type draft gear assembly (10) includes a housing (12) having an open front and a closed rear end with a first and second rear portions (13, 15) and a pair of ledge members (14) disposed intermediate such first and second rear portions and enabling the draft gear assembly (10) to fit into a draft gear pocket of a predetermined length. The first rear portion (13) is adapted to receive a compressible cushioning element (18) with a seating arrangement abutting one end thereof which extends longitudinally from the second portion (15) of the closed rear end toward the open front portion (20). The open front end is adapted to receive a friction cushioning element (42) which has a spring release mechanism (76) for continuously urging the friction cushioning element (42) outwardly from the compressible cushioning element (18) thereby releaseing such friction cushioning element after compression of such draft gear assembly (10). The open front end may incorporate additional side members (50) for direct attachment to a coupler.

Cette invention concerne un ensemble amortisseur de choc de traction du type à friction (10) comprenant un logement (12) à extrémité avant ouverte et extrémité arrière fermée, avec une première et une seconde parties arrière (13, 15) et une paire d'éléments de rebord (14) disposés entre les première et seconde parties arrière, qui permettent à l'ensemble amortisseur de choc de traction (10) de s'emboîter dans une poche de longueur déterminée. La première partie arrière (13) est conçue pour recevoir un élément amortisseur compressible (18) avec assise venant en butée, qui s'étend longitudinalement de la seconde partie (15) de l'arrière fermé vers la partie avant ouverte (20). Cette partie avant ouverte est conçue pour recevoir un élément amortisseur à friction (42) doté d'un mécanisme de libération à ressort (76) qui le repousse en permanence vers l'extérieur depuis de l'élément amortisseur compressible (18), ce qui libère ledit élément amortisseur à friction après compression de l'ensemble amortisseur de choc de traction (10). L'extrémité ouverte avant peut comporter (50) se fixant directement au coupleur. des éléments latéraux supplémentaires
