HYDROSTATISCHER FAHRANTRIEB UND VERFAHREN ZUM BETREIBEN DES HYDROSTATISCHEN FAHRANTRIEBS

HYDROSTATIC DRIVE AND METHOD FOR OPERATING SUCH A HYDROSTATIC DRIVE
(FR)
ENTRAINEMENT HYDROSTATIQUE ET PROCEDE D'UTILISATION D'UN ENTRAINEMENT HYDROSTATIQUE
Abstract:
(DE)
Ein hydrostatischer Fahrantrieb (1) umfasst eine Hydropumpe (3) und mehrere mit der Hydropumpe (3) hydraulisch verbundene Hydromotoren (6-9). Jedem Hydromotor (6; 7; 8; 9) ist jeweils ein Drehzahlsensor (20; 21; 22; 23) zugeordnet, der jeweils mit einer Steuereinheit (24) verbunden ist und die Drehzahl (n
1
; n
2
; n
3
, n
4
) des zugeordneten Hydromotors (6; 7; 8; 9) erfasst. Mit jedem Hydromotor (6; 7; 8; 9) steht jeweils eine Bremseinrichtung (26; 27; 28; 29) in Wirkverbindung, die mit der Steuereinheit (24) verbunden ist. Beim Überschreiten der Drehzahl (n
1
; n
2
; n
3
; n
4
) eines der Hydromotoren (6; 7; 8; 9) über einen vorgegebenen Grenzwert (n
g
) löst die Steuereinrichtung (24) die diesem Hydromotor (6; 7; 8; 9) zugeordnete Bremseinrichtung (26; 27; 28; 29) aus.
(EN)
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 a respective hydraulic motor (6; 7; 8; 9) and is linked with a control device (24) and detects the speed (n
1
; n
2
; n
3
, n
4
) 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 (n
1
; n
2
; n
3
; n
4
) 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).
(FR)
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 (n
1
; n
2
; n
3
, n
4
) 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 (n
1
; n
2
; n
3
, n
4
) d'un des moteurs hydrauliques (6; 7; 8; 9) dépasse une valeur seuil (n
g
), l'unité de commande (24) déclenche l'unité de freinage (26; 27; 28; 29) affectée à ce moteur hydraulique (6; 7; 8; 9).
