Abstract

L'invention concerne un antivibrateur pour groupe moteur de camion à benne déversante pour mine comportant un cylindre de support (1). Le cylindre de support (1) comporte un corps de cylindre (11) et une bride d'appui (12). La bride d'appui (12) s'étend à l'extérieur depuis le bord supérieur du corps de cylindre (11) de manière flexible. Un bloc de caoutchouc amortisseur de vibrations (2) est disposé sur le cylindre de support (1). Le bloc de caoutchouc (2) comporte une partie d'appui inférieure (21) et une partie d'appui supérieure (22). La partie d'appui inférieure (21) est disposée dans le corps de cylindre (11). Le bord de la partie d'appui supérieure (22) s'étend à l'extérieur depuis le bord supérieur de la partie d'appui inférieure (21) pour former une bride de caoutchouc (221). La bride de caoutchouc (221) est supportée par la bride d'appui (12). La surface supérieure de la partie d'appui supérieure (22) est sphérique. Des trous traversants (23) sont disposés dans le bloc de caoutchouc (2). Les trous traversants (23) pénètrent au travers d'une tige filetée (4). Un bloc de compression supérieur (5) est manchonné au niveau de la partie intermédiaire de la tige filetée (4). Le bloc de compression supérieur (5) comporte une partie d'entrée supérieure (52) et une partie de compression supérieure (51). La partie d'entrée supérieure (52) et la partie de compression supérieure (51) forment des gradins. L'extrémité inférieure de la partie d'entrée supérieure (52) est insérée dans le trou traversant. Une plaque de pression (7) est manchonnée sur une partie d'insertion supérieure (52) entre la partie de compression supérieure (51) et la partie d'appui supérieure (22). Une plaque de couvercle supérieure (8) est montée sur l'extrémité supérieure de la tige filetée (4). Un espace est formé entre la plaque de couvercle supérieure (8) et la partie de compression supérieure (51). La structure a un excellent effet d'absorption des vibrations.
