Abstract

L'invention concerne une transmission hydraulique à variation continue comprenant un piston (1), une plaque de commande de transmission (2), une roue d'entraînement (3) et une cavité hydraulique (4), un orifice de sortie (6) et un orifice d'entrée (7) étant prévus sur la cavité hydraulique, l'orifice de sortie et l'orifice d'entrée sont tous deux pourvus d'un clapet anti-retour (8), et l'orifice d'entrée est relié à la roue d'entraînement par l'intermédiaire d'un canal de retour de circulation d'huile propulsée (11). Après mise sous pression par le piston, l'huile propulsée pénètre dans un trou de distribution (10) d'huile propulsée pour pousser la roue d'entraînement afin de l'amener à tourner, et une fois le processus de poussée de la roue d'entraînement terminé, l'huile propulsée est de nouveau extraite et comprimée de nouveau pour appuyer sur le piston par l'intermédiaire du canal de retour de circulation d'huile propulsée et de l'orifice d'entrée. Pendant le processus de circulation, l'huile propulsée participe dans sa totalité, la distribution d'énergie est directe et l'efficacité est proche de 100 %, et la transmission hydraulique à variation continue peut fournir un couple relativement important, ce qui peut permettre une sortie directe de la puissance, une administration directe sans pertes, ce qui permet de réduire la perte énergétique. Dans le même temps, l'huile propulsée est renvoyée par l'intermédiaire du canal de retour de circulation, ce qui permet en outre de réaliser l'objectif d'économie d'énergie et de protection de l'environnement.
