Title (EN) WORKING VEHICLE
(FR) VÉHICULE DE TRAVAIL
(JA) 作業車両
Abstract:
(EN) This working vehicle is equipped with an engine 5 mounted on a traveling machine body 2, a rectilinear system transmission path comprising a first continuously variable transmission 17, and a turning system transmission path comprising a second continuously variable transmission 13, and drives left and right travel parts 3 by combining the output of the rectilinear system transmission path and the output of the turning system transmission path. This working vehicle is also equipped with: control units 813, 814 that control the output of the rectilinear system transmission path and the output of the turning system transmission path in coordination with each other; and a power connection/disconnection mechanism that connects/disconnects the transmission of power from the rectilinear system transmission path. If the transmission of power from the rectilinear system transmission path is disconnected by the power connection/disconnection mechanism, control unit 814 restricts the output of the turning system transmission path, and prohibits rotational motion in the mutually opposite directions of the left and right traveling units 3.
(FR) L'invention concerne un véhicule de travail, lequel véhicule comporte un moteur (5) monté sur un corps de machine en déplacement (2), une trajectoire de transmission de système rectiligne comprenant une première transmission variable en continu (17), et une trajectoire de transmission de système de virage comprenant une seconde transmission variable en continu (13), et entraînant des parties de déplacement gauche et droite (3) par la combinaison de la sortie de la trajectoire de transmission de système rectiligne et de la sortie de la trajectoire de transmission de système de virage. Ce véhicule de travail comporte également : des unités de commande (813, 814) qui commandent la sortie de la trajectoire de transmission de système rectiligne et la sortie de la trajectoire de transmission de système de virage en coordination l'une avec l'autre ; et un mécanisme de connexion/déconnexion de puissance qui connecte/déconnecte la transmission de puissance vis-à-vis de la trajectoire de transmission de système rectiligne. Si la transmission de puissance à partir de la trajectoire de transmission de système rectiligne est déconnectée par le mécanisme de connexion/déconnexion de puissance, l'unité de commande (814) restreint la sortie de la trajectoire de transmission de système de virage, et empêche un mouvement de rotation dans les directions mutuellement opposées des unités de déplacement gauche et droite (3).
(JA) 作業車両は、走行機体2に搭載するエンジン5と、第一無段変速装置17を有する直進系伝動経路と、第二無段変速装置13を有する旋回系伝動経路を備え、直進系伝動経路の出力と旋回系伝動経路の出力を合成して左右の走行部3を駆動する。また、作業車両は、直進系伝動経路の出力と旋回系伝動経路の出力とを連動的に制御する制御部813,814と、直進系伝動経路からの動力伝達を継断する動力継断機構とを備えている。制御部814は、動力継断機構により直進系伝動経路からの動力伝達が遮断された場合、旋回系伝動経路の出力を制限して、左右の走行部3による相互の逆転動作を禁止する。
