Description
Die Erfindung betrifft einen Hydraulikzylinder gemäß dem Oberbegriff des Hauptanspruchs.The invention relates to a hydraulic cylinder according to the Preamble to the main claim.
Ein solcher vorzugsweise einfach wirkender Hydraulikzylinder benötigt einen Endanschlag für die Kolbenstange. Diese wird bei der Montage in das einseitig offene Zylindergehäuse eingesetzt. Danach muß ein gesonderter Endanschlag, beispielsweise durch Anbringen einer Schraubverbindung aufgebracht werden, welcher verhindert, daß die Kolbenstange bei Beaufschlagung des Zylinderraums zu weit aus dem Zylindergehäuse heraus bewegt wird.Such a preferably single-acting hydraulic cylinder requires an end stop for the piston rod. These is inserted into the cylinder housing, which is open on one side, during assembly. Then a separate end stop, for example be applied by attaching a screw connection, which prevents the piston rod at Actuation of the cylinder space too far from the cylinder housing is moved out.
Der Erfindung liegt die Aufgabe zugrunde, einen Hydraulikzylinder gemäß dem Oberbegriff des Hauptanspruchs mit weniger Bauteilen und einfacher montierbar auszugestalten.The invention is based on the object of providing a hydraulic cylinder according to the preamble of the main claim with less Design components and easier to assemble.
IJiuiiü Aufgabe wird bei einem Hydraulikzylinder gemäß dem Oberbegriff des Hauptanspruchs erfindungsgemäß durch dessen kennzeichnende Merkmale gelöst. Infolge der Ausgestaltung des öffnungsseitigen Endes des Zylindergehäuses und des einzusetzenden Endes der Kolbenstange kann diese in einfacher Wüi lic in da:; /.yl i ncJ η r<) nhäti :;o e i ny-oso I: ·/. 1: und nach dom Minsetzen durch Verdrehen gesichert werden. Hierdurch bedingt, kommen die Nocken der Kolbenstange an den von Nuten freien Bereichen des Zylindergehäuses beim Endanschlag zur Anlage,The object is achieved according to the invention in a hydraulic cylinder according to the preamble of the main claim by its characterizing features. As a result of the design of the end of the cylinder housing on the opening side and the end of the piston rod to be inserted, this can be done in a simple manner in da :; /.yl i ncJ η r <) nhäti:; oei ny-oso I: · /. 1: and secured by twisting after inserting the dome. As a result, the cams of the piston rod come to rest on the areas of the cylinder housing free of grooves at the end stop,
Erfindungsgemäß ergibt sich also der Vorteil, daß im Gegensatz zum Stand der Technik der Hydraulikzylinder aus nur zwei darüber hinaus einfach herzustellenden Teilen besteht, die darüber hinau.s schnell und in einfacher Weise montiert werden können.According to the invention there is thus the advantage that in contrast to the state of the art, the hydraulic cylinder consists of only two parts that are easy to manufacture, which is also installed quickly and easily can be.

Zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Appropriate refinements and developments of the invention are characterized in the subclaims.
Mit der nachfolgenden Beschreibung wird die Erfindung anhand eines bevorzugten Ausführungsbeispieles näher erläutert. Es zeigt:The invention is illustrated by the following description a preferred embodiment explained in more detail. It shows:

Fig. 2 einen Schnitt II-II gemäß Fig. 1FIG. 2 shows a section II-II according to FIG. 1
undand
Fig. 3 einen Schnitt III-III gemäß Fig. 1.3 shows a section III-III according to FIG. 1.
Der insgesamt mit 5 bezeichnete Hydraulikzylinder weist ein ^ylindergehäuse 6 mit einem Anschluß 7 für die Hydraulikflüssigkeit und eine Kolbenstange 8 mit vorgegebenem Durchmesser y auf. Sowohl das Zylindergehäuse 6 als auch die Kolbenstange 8 weist ein Auge 10 zur Aufnahme eines Bolzens auf, dessen Achse - senkrecht zur Ebene der Zeichnung - senkrecht zur üubrich Luny 11 vorlüuΓt. Uio Achsen beider Augen sind in der eingebauten Laye zueinander parallel ausgerichtet und werden in dieser Stellung gehalten.The hydraulic cylinder designated as a whole with 5 has a cylinder housing 6 with a connection 7 for the hydraulic fluid and a piston rod 8 with a predetermined diameter y. Both the cylinder housing 6 and the piston rod 8 has an eye 10 for receiving a bolt, the axis of which - perpendicular to the plane of the drawing - perpendicular to üubrich Luny 11 vorlüuΓt. Uio axes of both eyes are in the built-in layers are aligned parallel to each other held in this position.
An dem einseitig offenen Ende 12 des Zylindergehäuses 6 sind l'ornor - <in .sich IjOk1IOnLo - Dichtungen für die Kolbenstange vorgesehen.At the end 12 of the cylinder housing 6, which is open on one side, l'ornor - <in .sich IjOk 1 IOnLo - seals for the piston rod are provided.

Ausweislich der Fig. 3 sind die Nocken 14 diametral einander gegenüberliegend angeordnet und senkrecht zur Achse der Augen 10. Mit den Nocken 14 wird die Kolbenstange 8 an der Innenseite 15 des Zylindergehäuses 6 geführt.As evidenced by FIG. 3, the cams 14 are arranged diametrically opposite one another and perpendicular to the axis of the eyes 10. The piston rod 8 is guided on the inside 15 of the cylinder housing 6 with the cams 14.
Entsprechend der Form und Anzahl sowie Ausdehnung der Nocken 14 weist das Zylindergehäuse 6 an seinem einseitig offenen Ende 12 im Bereich 16 gleichen Durchmessers wie der Durchmesser 9 der Kolbenstange 8 entsprechend ausgebildete Nuten 17 auf, die einander diametral ebenfalls gegenüberliegen (Fig.2), jedoch um 90° gedreht mit Bezug auf die Nocken 14 in Einbaulage (Fig. 3) .According to the shape and number as well as the extension of the cams 14 has the cylinder housing 6 at its end 12 open on one side in the area 16 of the same diameter as the diameter 9 of the piston rod 8 correspondingly formed grooves 17 which are also diametrically opposite one another (FIG. 2), but rotated by 90 ° with respect to the cams 14 in the installed position (Fig. 3).
