Description
Kupplund für Kraftfahrzeuge mit selbsttätiger NachstulluU Bei Betätigung hydraulisch zur Wirkung kommender Kupplungen von Kraftfahrzeugen wird der Kupplungsvorgang gesteuert von einem hydraulisohen Zylinder, der durch Betätigung des Fußhebeln druckbeaufsahlagt wird und dessen Kolben vermittels eines an seinem vorderen Ende angeordneten Kugellagerringen auf einen Druckring wirkt, der seinerseits/ Ton Kupplungavorgang bewirkende Hebel betätigt: Bach Beendigung den Kupplungsvorgangen wird der Kolben bisher unter Abhebung den Kugellagerringen von dem Druckring vermittels Rüokzugefedern bis zu einem Anschlag zurückgeführt, der der Nach- stellung bedarf und darum von Hand verstellbar ist. Clutches and for motor vehicles with automatic replenishment When the clutches of motor vehicles that come into effect hydraulically are actuated, the coupling process is controlled by a hydraulic cylinder which is pressurized by actuating the foot lever and whose piston acts on a pressure ring by means of a ball bearing ring at its front end , which in turn / The lever that causes the clutch operation is actuated: Bach ended the clutch operation, the piston is so far returned to a stop by lifting the ball bearing rings from the pressure ring by means of spring-loaded springs , which requires readjustment and is therefore adjustable by hand.
Der Erfindung liegt die Aufgabe zugrunde, die Kupplungseinrichtung so auszubilden, daß die Notwendigkeit einer Nach-Stellung der Rüekzugnbegrenzung den Kolbens von Hand ent- fällt. Dies, wird erfindungsgemäß dadurch erreicht, daß unter Fortlassung mechanischer Mittel zur Rückführung und Begrenzung den Rückwegen des Kolbens zwischen dem Kugel- lagerring und dem Druckring ein Gleitring aus einem Material mit niedrigem Reibungskoeffizient angeordnet ist, Bei einer in dieser Weise ausgebildeten Kupplung ist der Rückzugeweg des Kolbens, der nach Wegnahme des auf ihn zur Wirkung ge- brachten hydraulischen Druckes selbsttätig zurückgeht, durch den jeweils im hydraulischen System sich einstellenden hydrostatischen Druck begrenzt und der Kolben stellt sich infolgedessen in Abhängigkeit von diesem hydrostatischen Druck jeweils auf eine Stellung ein, in der er den Kugellagerring noch leicht gegen den Druckring drückt, wobei nachteilige Wirkungen infolge Reibung jedoch nicht auftreten können, da die-wegen des geringen Berührungsdrucken an sich schon geringe Reibung durch die erfindungsgemäß zwischengeschaltete Gleitscheibe nahezu unwirksam wird. The invention has for its object to design the coupling device such that the need for a post-position of the Rüekzugnbegrenzung falls the piston by hand corresponds. This is, according to the invention achieved in that mechanical omitting means for recycling and limitation bearing ring the return motion of the piston between the ball and the pressure ring a sliding ring is arranged made of a material with a low friction coefficient, In a constructed in this manner, coupling of the Rückzugeweg is the Piston, which automatically returns after the hydraulic pressure applied to it is removed , is limited by the hydrostatic pressure that is established in the hydraulic system and the piston is consequently adjusted to a position in which it is dependent on this hydrostatic pressure the ball bearing ring still presses lightly against the pressure ring, but disadvantageous effects due to friction cannot occur since the friction, which is already low due to the low contact pressure, is almost ineffective due to the sliding washer according to the invention .
Die Erfindung ist in der Zeichnung beispielsweise veranschaulicht und wird anhand der Zeichnung nachfolgend näher erläutert.The invention is illustrated in the drawing, for example and is explained in more detail below with reference to the drawing.
In der Zeichnung sind mit i das Gehäuse einer Fahrzeugkupplung, mit@2 der den Kupplungsvorgang steuernde hydraulische Zylinder und mit 3 der über einen hydraulischen Zylinder 4 zur Betätigung der Kupplung dienende Fußhebel bezeichnet. Der in dem hydraulischen Zylinder 2 geführte Kolben 5 wirkt vermittele eines Kugellagerringes 6 auf einen Druckring 7, der seinerseits bei Betätigung des Fußhebels 3 den Kupplungsring 8 vermittels rundum verteilter Hebel 9 von der Kupplungseeheibe 1o abhebt. Mit 11 ist eine der bei Wegnahme des auf den. Kolben 5 wirkenden hydraulischen Druckes wirksam werdenden Druckfedern bezeichnet.In the drawing, i denotes the housing of a vehicle clutch, and @ 2 the hydraulic cylinder controlling the coupling process and with 3 the one hydraulic cylinder 4 designated for actuating the clutch serving foot lever. The piston 5 guided in the hydraulic cylinder 2 acts by means of a ball bearing ring 6 on a pressure ring 7, which in turn when the foot lever is operated 3 the coupling ring 8 by means of levers 9 distributed all around from the coupling plate 1o takes off. With 11 is one of the when the on the. Piston 5 acting hydraulic Pressure acting compression springs called.
Erfindungsgemäß sind die Rückzugsfeder, die bisher die Zurückführung des druckentlasteten Kolbens 5 bis zu einem Anschlag bewirkt , und demgemäß auch der Anschlag in Fortfall gekommen. Der Kolben 5 geht nunmehr bei Wegnahme des auf ihn zur Wirkung gebrachten hydraulischen Druckes selbsttätig so weit zurück, wie es der im hydraulischen System sich einstellende hydrostatische Druck erlaubt. In Abhängigkeit von diesem hydraulischen Druck nimmt er jeweils eine Stellung ein, in der der Kugellagerring 6 noch leicht' gegen den Druckring 7 gedrückt wird. Um den hierdurch auftretenden, an sich schon geringen Berührungsdruck und die durch ihn verursachte geringe, an sißh schon nicht nachteilige Reibung völlig unschädlich zu machens ist erfindungegemäß zWieehen dem Kugellagerring 6 und dem Druckring 7 ein Gleitring 12 angeordnet, durch den eine mögliche Iteibung um so wirkeaier ausgeschaltet wird, je geringer der Reibungekoefi'izient ist, den er infolge geeigneter Material- Wahl oder zweckbestimmter Behandlung aufweist. Da nach der Erfindung das bisher vorhandene Spiel zwischen dem Kugellagerring und dem Druckring entfällt, ergibt sich auch der Vorteil, daß der Totweg am Fußhebel 3 geringer und damit das Gefühl beim Kuppeln sicherer wird.According to the invention, the return spring, which previously caused the pressure-relieved piston 5 to be returned to a stop, and accordingly also the stop, are no longer available. When the hydraulic pressure applied to it is removed, the piston 5 automatically goes back as far as the hydrostatic pressure which is established in the hydraulic system allows. Depending on this hydraulic pressure, it assumes a position in which the ball bearing ring 6 is still slightly pressed against the pressure ring 7. According to the invention, a sliding ring 12 is arranged between the ball bearing ring 6 and the pressure ring 7, in order to render the resulting, already low contact pressure and the low friction caused by it, which is not disadvantageous in itself, all the more effective is switched off, the lower the coefficient of friction it has as a result of a suitable choice of material or specific treatment. Since, according to the invention, the previously existing play between the ball bearing ring and the pressure ring is eliminated, there is also the advantage that the dead travel on the foot lever 3 is less and the feeling when coupling is more secure.
