Abstract

La présente invention concerne une structure de raccordement de béquilles et de traverses comprenant une paire de supports de raccordement de béquilles (3). Une face externe de chaque support de raccordement de béquilles (3) est raccordée à une face interne d'une partie supérieure d'une béquille (1) d'un châssis de semi-remorque. Une face interne de chaque support de raccordement de béquilles (3) est raccordée à une face externe d'une barre transversale (5) du châssis de semi-remorque. Une partie supérieure de chaque support de raccordement de béquilles (3) est raccordée à une partie inférieure d'une traverse principale (2) de la semi-remorque. Des parties inférieures des supports de raccordement de béquilles (3) sont raccordées les unes aux autres par une traverse de support (4) qui est parallèle à la traverse principale (2) pour former une structure en boucle fermée. Ainsi, une voie de transmission de la force en boucle fermée est formée, laquelle améliore l'état de support de force du châssis de semi-remorque et forme une structure plus compacte et présente un aspect plus agréable.
