Abstract
Description
Die Erfindung betrifft eine hydraulische Kupplungsbetätigung für ein Kraftfahrzeug gemäß den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a hydraulic clutch actuation for a motor vehicle according to the characteristics the preamble of claim 1.
Bei hydraulischen Kupplungsbetätigungen, bei
denen der im Druckraum des Geberzylinders erzeugte Flüssigkeitsdruck
am Kolben des ebenfalls in einer Hydraulikleitung integrierten Nehmerzylinders eine
Kraft erzeugt, mit deren Hilfe die Kupplung ausgerückt wird,
ist es bekannt, mit Hilfe einer in der Hydraulikleitung integrierten
Drosseleinrichtung eine von der Strömungsrichtung abhängige, unterschiedliche
Durchflusscharakteristik zu erzeugen. Für den Ausrückvorgang der Reibungskupplung
ist ein ungedrosselter Durchfluss gewünscht, während für den Einrückvorgang ein gedrosselter
Durchfluss erwünscht
ist, wenn ein zu schnelles Einrücken
der Fahrzeugkupplung, insbesondere beim ungewollten Abrutschen vom
Kupplungspedal, im Antriebsstrang Spitzenmomente erzeugt, die zu
Zerstörungen
von Antriebstrangbauteilen führen
können.
Dazu sind aus dem Stand der Technik verschiedene Ausführungsformen
von Drosseleinrichtungen bekannt (siehe z. B.
Aufgabe der Erfindung ist es, eine aus wenigen Bauteilen bestehende Drosseleinrichtung zu entwickeln, mit der zuverlässig der insbesondere eingangs beschriebene „misuse" der Kupplung abgefangen wird, ohne jedoch den gesamten Zeitablauf des Ein- bzw. Auskuppelns spürbar zu verlängern.The object of the invention is a to develop throttle device consisting of a few components, with the reliable the "misuse" of the clutch, described in particular at the beginning, is intercepted without however, the entire timing of engaging and disengaging noticeably extend.
Die Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.The task is set out in the claim 1 specified features solved.
Die Vorrichtung zeichnet sich durch einen einfachen Aufbau aus, durch den dennoch gewährleistet ist, dass zum Einrückzeitpunkt der Kupplung der Volumenstrom zwischen Nehmer- und Geberzylinder verringert ist, wodurch der Druck auf der Seite des Nehmerzylinders ansteigt und damit die Pedalgeschwindigkeit bzw.The device is characterized by a simple structure, which nevertheless ensures is that at the time of engagement the clutch the volume flow between slave and master cylinder is reduced, reducing the pressure on the slave cylinder side increases and thus the pedal speed or
Einrückgeschwindigkeit der Kupplung reduziert ist. Durch eine zweite im Kolben vorhandene Öffnung, die durch ein Rückschlagventil überwacht ist, wird sicher gestellt, dass der Ausrückvorgang bzw. das Auskuppeln nahezu ohne Zeitverlust erfolgen kann, da der Volumenstrom mit nur geringem Druckverlust vom Geberzylinder über das geöffnete Rückschlagventil zum Nehmerzylinder geleitet wird.Clutch engagement speed is reduced. Through a second opening in the piston, which is monitored by a check valve, it is ensured that the disengagement process or the disengagement can be done with almost no loss of time since the volume flow with only low pressure loss from the master cylinder via the open check valve to the slave cylinder is directed.
Durch die in den Unteransprüchen aufgeführten Merkmale sind weitere vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Vorrichtung möglich.By the features listed in the subclaims are further advantageous refinements and developments of device according to the invention possible.
Die als Drosselstelle wirkende Öffnung im Kolben ist auf vorteilhafte Art und Weise als feste Drosselblende ausgebildet.The opening in the piston that acts as a throttle is advantageously designed as a fixed throttle orifice.
Die in dem einen Druckraum der Drosseleinrichtung angeordnete Feder stellt sicher, dass sich der Kolben bei ausgerückter Kupplung immer in der vorgesehenen Anschlagposition befindet.The one in the pressure chamber of the throttle device The arranged spring ensures that the piston moves when the clutch is disengaged is always in the intended stop position.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, das nachfolgend näher beschrieben ist.In the drawing, an embodiment of the Invention shown, which is described in more detail below.
Es zeigen:Show it:

Im nachfolgenden wird die Funktionsweise der Drosseleinrichtung näher erläutert:Below is how it works the throttle device explained in more detail:
1. Einkupplungsvorgang1. Coupling process
Durch das Loslassen des Kupplungspedals
2. Auskuppelvorgang2. Disengaging process
Beim Auskuppeln wird der Kolben
Die erfindungsgemäße Drosseleinrichtung kann sowohl als separates Bauteil zwischen Kupplungsnehmer- und Kupplungsgeberzylinder angeordnet sein, als auch in den beiden zuletzt genannten Bauteilen integriert sein.The throttle device according to the invention can both as a separate component between the clutch slave and clutch master cylinder be arranged, as well as in the last two components mentioned be integrated.
