Abstract

L'invention concerne un bogie équipé d'un châssis secondaire et destiné à des wagons comportant deux essieux (1), deux longerons (2) et une traverse danseuse (3). Les essieux (1) gauche et droit forment un ensemble essieu en s'assemblant à un timon. Un adaptateur (5) est placé à une extrémité du timon, respectivement. Les longerons (2) de bogie sont montés sur les adaptateurs (5) des essieux (1) gauche et droit. Des éléments élastiques (8) sont placés entre les longerons (2) de bogie et les adaptateurs (5). Le bogie comporte un dispositif d'autoguidage (4). Le dispositif d'autoguidage (4) comprend des cadres auxiliaires (6) et des bielles (7). Les deux extrémités des cadres auxiliaires (6) sont montées sur les adaptateurs (5) des essieux (1) gauche et droit. Les deux cadres auxiliaires (6) sont reliés l'un à l'autre par les deux bielles (7).
