Abstract

La présente invention concerne un mécanisme radial d'essieu de bogie ayant une structure dont la rigidité est réglable. Le mécanisme est composé de cadres secondaires avant et arrière (21) qui sont reliés par broche par l'intermédiaire de deux tiges de liaison (22) agencées de manière transversale. Les tiges de liaison (22) sont reliées par broche aux cadres secondaires (21) par l'intermédiaire de broches rondes (24). Des joints entre les broches rondes (24) et les tiges de liaison (22) et/ou des joints entre les broches rondes et les cadres secondaires (21) sont dotés de matériaux élastiques remplaçables. Les joints entre les broches rondes (24) et les tiges de liaison (22) et/ou les joints entre les broches rondes et les cadres secondaires (21) sont dotés d'anneaux (23) constitués des matériaux élastiques remplaçables. Des parties extrémité des tiges de liaison (22) sont incorporées dans des rainures de montage (25) situées dans les cadres secondaires (21) et sont reliées par broche à celles-ci par l'intermédiaire des broches rondes (24). Les parties extrémité des tiges de liaison (22) sont situées sur un plan de montage supérieur (31) ou un plan de montage inférieur (32) des cadres secondaires (21) et sont reliées par broche à celles-ci par l'intermédiaire des broches rondes (24). En fournissant les matériaux élastiques remplaçables, qui ont des effets tampon et d'amortissement, des forces d'impact entre les broches rondes (24) et les cadres secondaires (21) et entre les broches rondes (24) et les tiges de liaison (22) sont efficacement réduites, ce qui permet d'améliorer davantage la fiabilité d'utilisation des cadres secondaires (21) et des tiges de liaison (22), et de réduire le risque de défaillance structurelle de chaque partie.
