Title (EN) AGRICULTURAL VEHICLE DRIVELINE
(FR) CHAÎNE CINÉMATIQUE DE VÉHICULE AGRICOLE
Abstract:
(EN) A drivetrain for an agricultural vehicle and method for controlling the same. The drivetrain comprises first and second driven axles with a variable pivot angle hydraulic motor (144) connectable to drive the first axle through engagement of a first clutch mechanism (166). A further motor (142) is connected to drive the second axle. In operation, the pivot angle (β) of the variable pivot angle hydraulic motor (144) is reduced with variation in a vehicle parameter value, such as transmission ratio or ground speed, to a point at which the pivot angle reaches zero at a first parameter value. With the pivot angle (β) at zero and parameter value continuing to vary due to the drive of the further motor (142), the first clutch mechanism (166) is disengaged at a second parameter value, with the first and second parameter values separated by an interval (I) determined at least partly by an operating characteristic of the first clutch mechanism (166).
(FR) La présente invention concerne une chaîne cinématique destinée à un véhicule agricole et un procédé de commande correspondant. La chaîne cinématique comprend un premier et un second essieu mené dotés d'un moteur hydraulique (144) à angle de pivotement variable pouvant être raccordé pour entraîner le premier essieu par embrayage d'un premier mécanisme d'embrayage (166). Un autre moteur (142) est raccordé pour entraîner le second essieu. En cours de fonctionnement, l'angle de pivotement (β) du moteur hydraulique (144) à angle de pivotement variable est réduit avec une variation d'une valeur d'un paramètre du véhicule, telle qu'un rapport de transmission ou une vitesse au sol, à un point au niveau duquel l'angle de pivotement atteint zéro à une première valeur de paramètre. Lorsque l'angle de pivotement (β) est zéro et une valeur de paramètre continue à varier en raison de l'entraînement de l'autre moteur (142), le premier mécanisme d'embrayage (166) est désembrayé à une seconde valeur de paramètre, les première et seconde valeurs de paramètre étant séparées par un intervalle (I) déterminé au moins en partie par une caractéristique de fonctionnement du premier mécanisme d'embrayage (166).
