The invention relates to a hydrostatic drive (1) with a hydraulic pump (3) and a plurality of hydraulic motors (6-9) that are hydraulically linked with said hydraulic pump (3). One speed sensor (20; 21; 22; 23) each is allocated to the respective hydraulic motor (6; 7; 8; 9) and is linked with a control device (24) and detects the speed (n1; n2; n3; n4) of the allocated hydraulic motor (6; 7; 8; 9). Every hydraulic motor (6; 7; 8; 9) is functionally linked with a brake device (26; 27; 28; 29) that in turn is linked with the control device (24). When the speed (n1; n2; n3; n4) of one of the hydraulic motors (6; 7; 8; 9) exceeds a predetermined threshold value (n g), the control device (24) triggers the brake device (26; 27; 28; 29) allocated to said hydraulic motor (6; 7; 8; 9).
L'invention concerne un entraînement hydrostatique (1) composé d'une pompe hydraulique (3) et de plusieurs moteurs hydrauliques (6-9) reliés de manière hydraulique avec la pompe hydraulique (3). Un capteur de régime (20; 21; 22; 23) est respectivement affecté à chaque moteur hydraulique (6; 7; 8; 9), chaque capteur comportant une unité de commande (24) et enregistrant le régime (n1; n2; n3, n4) du moteur hydraulique correspondant (6; 7; 8; 9). Chaque moteur hydraulique (6; 7; 8; 9) est en interaction avec une unité de freinage (26; 27; 28; 29) reliée à l'unité de commande (24). Lorsque le régime (n1; n2; n3, n4) d'un des moteurs hydrauliques (6; 7; 8; 9) dépasse une valeur seuil (ng), l'unité de commande (24) déclenche l'unité de freinage (26; 27; 28; 29) affectée à ce moteur hydraulique (6; 7; 8; 9).
