Abstract

Système de régulation d'un dispositif d'entraînement comportant un moteur et un dispositif de transmission hydrostatique (avec une pompe hydraulique et un moteur hydraulique entraînant une charge) dont le rapport de transmission est asservi à la vitesse du moteur à partir d'un signal DELTA p2 . Un seul signal pilote (pression differentielle DELTA p 1 de part et d'autre d'un étranglement du circuit de commande) est produit, duquel sont déduits, dans un seul circuit de régulation, un nombre arbitraire de signaux de commande (Y 1 à Y6 ) destinés aux éléments (1, 2, 3, 36, 18, 13) de la chaîne de régulation selon le régime de fonctionnement du dispositif d'entraînement.Regulation system of a drive device comprising a motor and a hydrostatic transmission device (with a hydraulic pump and a hydraulic motor driving a load), the transmission ratio of which is slaved to the speed of the engine from a signal DELTA p2. A single pilot signal (differential pressure DELTA p 1 on either side of a throttle in the control circuit) is produced, from which are deduced, in a single control circuit, an arbitrary number of control signals (Y 1 to Y6) intended for the elements (1, 2, 3, 36, 18, 13) of the regulation chain according to the operating speed of the drive device.
