Abstract

L'invention concerne une transmission à dérivation de puissance (40) hydrostatique-mécanique à variation continue pour un véhicule utilitaire tel qu'une chargeuse sur roues. Dans cette transmission à dérivation de puissance (40), la puissance transmise par un moteur de combustion à un arbre moteur (21) est répartie par l'intermédiaire d'un train planétaire (22) entre une branche mécanique (26, 29) et une branche hydrostatique (H1, H2), et additionnée à l'aide de moyens totalisateurs (41) du côté sortie, la branche hydrostatique (H1, H2) comportant au moins un premier ensemble hydrostatique (H1) à cylindrée réglable, travaillant en pompe (P), et au moins un second ensemble hydrostatique (H2) à cylindrée réglable, travaillant en moteur (M), reliés par une liaison hydraulique, une plage de marche avant (V) et une plage de marche arrière (R) étant prévues. Pour obtenir une telle transmission à dérivation de puissance présentant une structure compacte, ainsi qu'un couple initial élevé et une grande gamme de vitesses lors de la marche avant et de la marche arrière, il est prévu que le parcours de la plage de marche avant (V) et de la plage de marche arrière (R) se fasse en continu uniquement par modification des cylindrées des ensembles hydrostatiques (H1, H2), et que la transmission comporte des seconds ensembles hydrostatiques (H2) travaillant en moteur (M), ainsi qu'un inverseur (32, 33, 34) pour le passage entre la plage de marche avant (V) et la plage de marche arrière (R).
