Abstract

Die Erfindung betrifft ein Antriebssystem (1) mit einer hydraulischen Kolbenmaschine (2) und einer lösbaren Kupplung (31) zum wahlweisen Trennen einer Triebwelle (11) der Kolbenmaschine (2), die durch ein Betätigungsmittel (35) betätigbar ist. Das Verdrängungsvolumen der Kolbenmaschine (2) ist durch eine Einstellvorrichtung (23) einstellbar und es ist eine Erfassungsvorrichtung (33) vorgesehen, die die Stellung der Einstellvorrichtung (23) zumindest im Bereich minimalen Verdrängungsvolumens erfaßt und das Betätigungsmittel (35) so aktiviert, daß es die Kupplung (31) öffnet, wenn die Einstellvorrichtung (23) sich im Bereich minimalen Verdrängungsvolumens befindet, und die Kupplung (31) schließt, wenn die Einstellvorrichtung (23) sich außerhalb des Bereichs minimalen Verdrängungsvolumens befindet.

Figure 00000001
The invention relates to a drive system (1) with a hydraulic piston machine (2) and a releasable clutch (31) for selectively disconnecting a drive shaft (11) of the piston machine (2) which can be actuated by an actuating means (35). The displacement volume of the piston machine (2) can be adjusted by an adjusting device (23) and a detection device (33) is provided which detects the position of the adjusting device (23) at least in the area of the minimal displacement volume and activates the actuating means (35) so that it the clutch (31) opens when the adjuster (23) is in the minimum displacement range and the clutch (31) closes when the adjuster (23) is outside the minimum displacement range.
