Description
Die Erfindung betrifft ein Betätigungssystem für eine Kupplung, mit einem hydrostatischen Kupplungsaktor, der einen Elektromotor umfasst, der eine Elektromotorwelle antreibt. Die Erfindung betrifft auch ein Verfahren zum Betreiben einer Kupplung mit einem derartigen Betätigungssystem. The invention relates to an actuating system for a clutch, comprising a hydrostatic clutch actuator comprising an electric motor which drives an electric motor shaft. The invention also relates to a method for operating a clutch with such an actuating system.
Aus der deutschen Offenlegungsschrift
Aufgabe der Erfindung ist es, die Funktionalität eines Betätigungssystems für eine Kupplung, mit einem hydrostatischen Kupplungsaktor, der einen Elektromotor umfasst, der eine Elektromotorwelle antreibt, auf einfache Art und Weise zu erhöhen. The object of the invention is to increase the functionality of an actuating system for a clutch, with a hydrostatic clutch actuator comprising an electric motor which drives an electric motor shaft in a simple manner.
Die Aufgabe ist bei einem Betätigungssystem für eine Kupplung, mit einem hydrostatischen Kupplungsaktor, der einen Elektromotor umfasst, der eine Elektromotorwelle antreibt, dadurch gelöst, dass die Elektromotorwelle des hydrostatischen Kupplungsaktors mechanisch mit einer Hydraulikpumpe gekoppelt ist, die hydraulisch mit einem hydraulischen Zwischenspeicher verbunden ist. Die Hydraulikpumpe dient zur Darstellung eines Erweiterungspakets oder Add-ons für das Betätigungssystem. Daher kann die Hydraulikpumpe auch als Add-on-Pumpe bezeichnet werden. The object is achieved in an actuating system for a clutch with a hydrostatic clutch actuator comprising an electric motor which drives an electric motor shaft, in that the electric motor shaft of the hydrostatic clutch actuator is mechanically coupled to a hydraulic pump which is hydraulically connected to a hydraulic buffer. The hydraulic pump is used to represent an expansion package or add-on for the actuation system. Therefore, the hydraulic pump may also be referred to as an add-on pump.
Ein bevorzugtes Ausführungsbeispiel des Betätigungssystems ist dadurch gekennzeichnet, dass die Hydraulikpumpe zwei Stromrichtungen aufweist und über Rückschlagventile so mit dem hydraulischen Zwischenspeicher verschaltet ist, dass der hydraulische Zwischenspeicher durch die Hydraulikpumpe aufgeladen werden kann. Mit Hilfe der in dem hydraulischen Zwischenspeicher gespeicherten hydraulischen Energie kann zum Beispiel in einem sogenannten Start-Stop-Betrieb eine unerwünschte Startverzögerung reduziert werden. Darüber hinaus kann mit Hilfe der Add-on-Pumpe auf einfache Art und Weise ein Boosten bei einem zusätzlich benötigten Druck/Volumenstrom dargestellt werden. Des Weiteren ermöglicht die Add-on-Pumpe einen Fail-Safe-Betrieb bei einem unerwünschten Ausfall des hydrostatischen Kupplungsaktors. A preferred embodiment of the actuating system is characterized in that the hydraulic pump has two flow directions and is connected via check valves so with the hydraulic buffer, that the hydraulic buffer can be charged by the hydraulic pump. With the help of the hydraulic energy stored in the hydraulic buffer, for example, in a so-called start-stop operation, an undesirable starting delay can be reduced. In addition, with the help of the add-on pump in a simple way a boost at an additional required pressure / flow rate can be displayed. Furthermore, the add-on pump allows fail-safe operation in the event of undesirable failure of the hydrostatic clutch actuator.
Ein weiteres bevorzugtes Ausführungsbeispiel des Betätigungssystems ist dadurch gekennzeichnet, dass die Hydraulikpumpe an die Elektromotorwelle des hydrostatischen Kupplungsaktors angeflanscht ist. Dadurch werden/wird die Herstellung und/oder die Montage der Add-on-Pumpe vereinfacht. A further preferred embodiment of the actuation system is characterized in that the hydraulic pump is flanged to the electric motor shaft of the hydrostatic clutch actuator. This simplifies the manufacture and / or assembly of the add-on pump.
Die Erfindung betrifft des Weiteren ein Verfahren zum Betreiben einer Kupplung mit einem vorab beschriebenen Betätigungssystem. The invention further relates to a method for operating a clutch with an actuating system described above.
