Description

Ausschaltvorrichtung für hydraulische Kupplungen. Die Ausschaltung erfolgt gegenüber Kupplungen bekannter Bauart mittels, eines an den äußeren Rand der verschiebbaren Reibscheiben verlegten Druckraumes. 'Diese Anordnung besitzt gegenüber jenen Anordnungen, bei welchen die Ausschaltung der versebiebbaren Reibscheiben mittels :eines: in der Nabe angeordneten Druckraumes erfolgt, die folgenden Vorteile: i. Kupplungen für die Übertragung größerer Kräfte, bei denen eine große Anzahl von Rillen- angeordnet werden müssen und große Durchmesser der Kupplungsischeiben erforderlich werden, erfordern zur Auerückung starke Kräfte, die auch bei niedrigen Drucke des Drucköls leicht gewonnen werden können mittels des am äußeren Rand der Reibscheiben angeordneten Druckraums, während die Gewinnung entsprechend großer Diruckflächen an den Naben: bei den Kupplungen bekannter Art den Durchmesser der Kupplung außerordentlich vergrößert.Disconnection device for hydraulic clutches. The elimination takes place in comparison to couplings of known design by means of one on the outer edge the sliding friction disks relocated pressure space. 'This arrangement possesses compared to those arrangements in which the elimination of the sliding friction disks by means of: a: pressure chamber arranged in the hub, the following advantages: i. Couplings for the transmission of larger forces where a large number of Grooved need to be arranged and large Diameter of the clutch discs are required, require strong forces for disengagement, even with low forces Prints of the pressure oil can easily be obtained by means of the on the outer edge of the Friction disks arranged pressure chamber, while the extraction is correspondingly larger Pressure surfaces on the hubs: in the case of the known type of couplings, the diameter of the Coupling greatly enlarged.

z. Ferner kann bei der. vorliegenden Erfindung bei eingerückter Kuplung das aus, dem Druckraum unvermeidlich durch die Abdichtungsflächen entweichende Drucköl nicht so leicht in das Kupplungsgehäuse entweichen und zu den Reibflächen gelangen, sondern es, tritt in den. zur Ausschaltung dienenden Druckraum über und wird von' hier in den Saugraum der D'ru@ckölpmnpe -geleitet, so@ daß: die Reibflächen leichter ölfrei gehalten werden. können.z. Furthermore, the. present invention with the clutch engaged the pressure oil that inevitably escapes from the pressure chamber through the sealing surfaces not easily escape into the clutch housing and reach the friction surfaces, but it occurs in the. to switch off the pressure chamber and is controlled by ' here in the suction chamber of the D'ru @ ckölpmnpe -directed, so @ that: the friction surfaces lighter are kept oil-free. can.

In -der Zeichnung sind zwei Ausführungsfortinen der Erfin!dumg angegeben.In the drawing, two execution continuations of the invention are indicated.

Bei der Ausführung nach: Abb. r besteht die Kupplung aus dem Gehäuseteil a, den beiden Reibscheiben b und c und den Druckräumen d und: e. Tritt D'rwcköl durch. die Zuleitung f in dien Druckraum d, so werden die Reibscheiben b und c an das Gehäuse a angepreßt; führt man Drucköl durch die Leitung ,g dem Druckraume zu, so findet die Entkupplung statt. Der auf der Welle angebrachte Bvndringh sichett :die Bewegung jeder der beiden Reibscheiben um denselben Betrag. Bei der Ausführung nach Abb. a besteht die Kupplung aus dem feststehenden Teil a und .den verschiebbaren Kupplungsteilen b und c. Der feststehende Teil a ist zum Zweck der Gewinnung einer möglichst schmalen Kupplung im Querschnitt zickzaakförmig gestaltet. Zuxn Zweck der Kupplung läßt man Drucköl- in den DTuckraurm d, zum Zweck der Entkupplung läßt man Drucköl in den Druckraum e eintreten. Bundringe At und i sichern die Bewegung der verschiebbaren Teile uni denselben Betrag.In the version according to: Fig. R, the clutch consists of the housing part a, the two friction disks b and c and the pressure chambers d and: e. Kick D'rcköl through. the supply line f in the pressure chamber d, the friction disks b and c are pressed against the housing a; If pressurized oil is fed through the line, g to the pressure chamber, the decoupling takes place. The ring attached to the shaft is locked: the movement of each of the two friction disks by the same amount. In the design according to Fig. A, the coupling consists of the fixed part a and the movable coupling parts b and c. The fixed part a is designed zigzag-shaped in cross section for the purpose of obtaining the narrowest possible coupling. For the purpose of the coupling, pressurized oil is allowed to enter the pressure chamber d, for the purpose of decoupling pressurized oil is allowed to enter the pressure chamber e. Collars At and i ensure the movement of the movable parts uni the same amount.
