Abstract

L'invention concerne un tampon à boisseau qui comprend un élément de guidage, se présentant sous la forme d'un manchon (10), et un élément guidé, se présentant sous la forme d'un boisseau (20). L'objectif de l'invention est de permettre une réduction de longueur importante pour la déformation contrôlée de la caisse d'amortisseur en cas de surcharge, ainsi qu'une longueur de chevauchement suffisamment grande en fonctionnement normal (compression sur toute la couse de l'amortisseur). A cet effet, au moins un (20) desdits éléments de guidage ou guidé (10, 20; 10, 50) est constitué d'au moins deux parties (22, 24; 52, 54) oblongues disposées l'une derrière l'autre. Ces parties (22, 24; 52, 54) oblongues sont, dans la zone de leurs faces adjacentes, reliées respectivement à un ou plusieurs points de rupture (23; 53) et présentent des sections transversales différentes, de telle sorte que, lorsqu'une certaine force d'impact (force de déclenchement) est dépassée au niveau de la cage d'amortisseur (1), le ou les point(s) de rupture (23; 53) prédéterminé(s) se rompent et les parties (22, 24; 52, 54) oblongues entrent l'une dans l'autre de façon télescopique.
