Abstract
Transmission hydromécanique à variation continue. Transmission hydromécanique à deux étages dont le premier comprend la marche arrière, dans laquelle la variation continue résulte d'une transmission hydrostatique caractérisée en ce qu'elle ne comporte que quatre arbres et en ce que les deux étages de sortie 13 et 14 peuvent être reliés chacun directement à un même arbre de sortie 16. L'invention intéresse les constructeurs de boîtes de transmission pour véhicules et engins.
