Abstract
Conformément à l'invention, la cale comporte une structure métallique comportant des parties évidées comblées par surmoulage avec un matériau élastomère semi-rigide. La cale comporte une zone centrale essentiellement métallique s'étendant jusqu'au bord latéral de la cale situé du côté de l'extrados de l'aube. La zone centrale métallique comporte un profil usiné en retrait par rapport au profil de l'alvéole, ce qui permet la rotation du pied de l'aube lors d'un choc violent. La cale (5) comporte deux zones extrêmes amont (10) et aval (11) de structure entièrement métallique et deux bords latéraux (13, 14, 15) en matériau élastomère sauf dans la zone centrale métallique (12). Entre les deux bords latéraux et de part et d'autre de la zone centrale métallique (12) la cale comporte une partie inférieure métallique (16,17) et une partie supérieure en élastomère (18, 19).
