Abstract

L'invention concerne un dispositif d'amenée de munitions comportant un entraînement de munitions (2) d'un système d'arme (21), notamment à entraînement externe, un élément d'amenée coulissant (9) étant incorporé afin de réaliser un dispositif d'amenée de munitions bilatéral avec seulement un entraînement de munitions (2). L'élément d'amenée (9) comporte deux systèmes de transport à courroie (30, 31) et est déplacé vers la gauche ou la droite en direction de l'entraînement de munitions (2) au moyen d'une denture (9.1) dans laquelle s'encastre un pignon (10.1) d'un entraînement (10). L'élément d'amenée (9) comporte une partie centrale (9.2) en forme de bascule, comprenant deux bras (9.2.1, 9.2.2) s'encastrant dans des évidements (9.3.1, 9.4.1) de deux axes qui sont également déplacés. Lors du déplacement, les deux axes (9.3, 9.4) sont déplacés avec l'élément d'amenée (9) jusqu'à ce que l'axe respectif (9.3, 9.4) atteigne son évidement correspondant (24.2, 24,1) et s'enfonce dans celui-ci, et bloque l'élément d'amenée (9). L'étoile de transport (30, 31) conçue de façon correspondant à l'entraînement de munitions (2) est reliée par son élément d'accouplement (32, 33) à l'entraînement de munitions (2), par l'élément d'accouplement (26) de celui-ci. Un engrenage à pignons coniques (4) est intégré à la chaîne cinématique pour le changement de sens de rotation de l'étoile de transport à courroie (30, 31) correspondante.
