Leg assembly (10) for an amphibious vehicle comprises leg (11) and hydraulic ram (33) each pivotally mounted, above the waterline, externally to hull (17). The line of action of ram (33) is such that it is optimal (eg less than 30~) with respect to the tangent to the arc of travel of leg (11) when it is lowered or raised. Leg (11) carries wheel (13) which may be swivelled for steering using hydraulic linear actuator (15). Assembly (10) is compact, light, yet capable of lifting the vehicle off the ground.

L'invention concerne un ensemble tige (10) conçue pour un véhicule amphibie et comprenant une tige (11) et un bras hydraulique (33) monté pivotant, au-dessus de la ligne d'eau, à l'extérieur de la coque (17). La ligne d'action du bras (33) est optimale (par exemple inférieure à 30·) par rapport à la tangente à l'arc du mouvement de la tige (11), lorsqu'elle est abaissée ou surélevée. La tige (11) supporte la roue (13), cette dernière pouvant pivoter lors de la commande au moyen d'un actionneur (15) linéaire hydraulique. L'ensemble (10) est compact, léger, capable de soulever le véhicule du sol.
