Title (EN) A TRANSMISSION SYSTEM
(FR) SYSTÈME DE TRANSMISSION
Abstract:
(EN) A transmission system (1) is arranged for transmitting power generated by an engine (2) of a vehicle. The transmission system (1) comprises a power take-off (3) for driving an implement and a hydrostatic unit (5) for transmitting power from the engine (2) to the power take-off (3). The hydrostatic unit (5) comprises: a first hydraulic power unit (6) having a first connection line (19) and a second connection line (20); a second hydraulic power unit (7) having a first connection line (21) and a second connection line (22); a valve (23) for connecting the first hydraulic power unit (6) and the second hydraulic power unit (7), the valve (23) being positionable at least in a first position, in a second position and in a neutral position. In the first position, the first connection line (19) and the second connection line (20) of the first hydraulic power unit (6) are connected respectively to the first connection line (21) and to the second connection line (22) of the second hydraulic power unit (7). In the second position, the first connection line (19) and the second connection line (20) of the first hydraulic power unit (6) are connected respectively to the second connection line (22) and to the first connection line (21) of the second hydraulic power unit (7). In the neutral position, the first hydraulic power unit (6) is disconnected from the second hydraulic power unit (7).
(FR) L'invention concerne un système de transmission (1) qui est conçu pour transmettre une puissance générée par un moteur (2) d'un véhicule. Le système de transmission (1) comprend une prise de puissance (3) permettant d'entraîner un instrument et une unité hydrostatique (5) permettant de transmettre la puissance du moteur (2) à la prise de puissance (3). L'unité hydrostatique (5) comprend : une première unité hydraulique (6) comportant une première ligne de connexion (19) et une seconde ligne de connexion (20) ; une seconde unité hydraulique (7) comportant une première ligne de connexion (21) et une seconde ligne de connexion (22) ; une soupape (23) permettant de connecter la première unité hydraulique (6) à la seconde unité hydraulique (7), la soupape (23) pouvant être positionnée au moins dans une première position, dans une seconde position et dans une position neutre. Dans la première position, la première ligne de connexion (19) et la seconde ligne de connexion (20) de la première unité hydraulique (6) sont connectées respectivement à la première ligne de connexion (21) et à la seconde ligne de connexion (22) de la seconde unité hydraulique (7). Dans la seconde position, la première ligne de connexion (19) et la seconde ligne de connexion (20) de la première unité hydraulique (6) sont connectées respectivement à la seconde ligne de connexion (22) et à la première ligne de connexion (21) de la seconde unité hydraulique (7). Dans la position neutre, la première unité hydraulique (6) est déconnectée de la seconde unité hydraulique (7).
