Description

  

      Wellengelenk.       Die Erfindung betrifft ein     Wellengelenk,     wie     es    z. B. für den     Vorderradantrieb    von  Kraftwagen verwendet wird. Hierzu sind       zwei    Kreuzgelenke erforderlich, um die not  wendige Gleichförmigkeit in der     Übertra-          gung    der     Bewegung    zu erzielen. Die Ausbil  dung als zwei Kreuzgelenke mit zwischen  geschaltetem     Wellenstück    ist nicht möglich,  da der Raumbedarf in diesem Falle zu gross  wäre.

   Ausserdem ist die Wellenzentrierung  schwierig, da zu     diesem.    Zwecke     besondere          Zentrierteile    durch die hohlen. Zapfenkreuze  durchgeleitet werden müssten. Bei einem be  kannten Wellengelenk sind die Kreuzgelenke  durch Laschen verbunden. Aber auch hier       erfordert    die Wellenzentrierung besondere       Zentrierteile.     



  Diese Nachteile sollen durch die Erfin  dung beseitigt sein. Das Wellengelenk nach  der Erfindung zeichnet sich dadurch aus, dass  die zwei     hintereinandergeschalteten    Kreuz  gelenke durch einen Ring verbunden sind;  wobei die Wellenenden in den Ring hinein  ragen und sich gegenseitig durch eine Kugel  in einem Hohlzylinder so führen, dass der       Achsenschnittpunkt    beider Wellen in bezug  auf eine der Wellen stets gleich bleibt. Zur  Ermöglichung einer zentralen Schmierung  kann am Ring oder an einem der beiden  Wellenenden ein Schmierkopf vorgesehen  sein, der durch Schmierkanäle mit allen Ge  lenkzapfenlagern und der Kugelführung -ver  bunden ist.

      Die Erfindung ermöglicht eine äusserst  gedrungene Bauart, welche den Einbau auch  in sehr raumbeengten Fahrzeugen     gestattet.     Ferner ist eine nahezu     vollkommene    Abdich  tung aller Lagerstellen erzielbar.  



  In der     Zeichnung    ist ein Ausführungs  beispiel der Erfindung dargestellt. Es zeigen:       Fig.    1 einen Schnitt durch das     Gelenk    in  der einen Zapfenebene,       Fig.    2 einen Schnitt durch das Gelenk in  der dazu senkrechten Zapfenebene und       Fig.3    einen Schnitt senkrecht zur Wel  lenrichtung.  



  Das     Wellengelenk        besitzt    einen Ring 1, an  dem beiderseits die beiden Zapfenkreuze 2, 3  drehbeweglich     angeordnet    sind. Durch die       Ausnehmungen    4, 5 der Zapfenkreuze 2, 3  sind die Fäuste 6, 7 der An- und Abtriebs=  wellen 8, 9 geführt, deren Zapfen 10, 11 in  den Lagern 12, 13 der     zugeordneten    Zapfen  kreuze 2, 3 ruhen.     Innerhalb    des Ringes 1 ist  die Kugel 14 am Ende der Antriebswelle 8 in  einem     Führungshohlzylinder    15 am Ende der       Abtriebswelle    9 gelagert.  



  Der Schmierkopf 16 am Ring 1 oder an  der Welle 9 dient zur Zentralschmierung aller  Lagerstellen des Gelenkes über die Kanäle k.



      Universal joint. The invention relates to a universal joint as it is, for. B. is used for the front wheel drive of motor vehicles. Two universal joints are required for this in order to achieve the necessary uniformity in the transmission of movement. The formation as two universal joints with a shaft piece connected between them is not possible because the space requirement would be too large in this case.

   In addition, shaft centering is difficult because of this. Purposes special centering parts through the hollow. Crosses would have to be passed through. In a known universal joint, the universal joints are connected by tabs. But here too, shaft centering requires special centering parts.



  These disadvantages should be eliminated by the inven tion. The universal joint according to the invention is characterized in that the two cross joints connected in series are connected by a ring; whereby the shaft ends protrude into the ring and lead each other through a ball in a hollow cylinder in such a way that the axis intersection of the two shafts with respect to one of the shafts always remains the same. To enable central lubrication, a lubrication head can be provided on the ring or on one of the two shaft ends, which is -ver connected through lubrication channels with all Ge pivot pin bearings and the ball guide.

      The invention enables an extremely compact design which allows installation in vehicles with very limited space. Furthermore, an almost complete waterproofing device of all bearings can be achieved.



  In the drawing, an execution example of the invention is shown. 1 shows a section through the joint in one pin plane, FIG. 2 shows a section through the joint in the pin plane perpendicular thereto, and FIG. 3 shows a section perpendicular to the shaft direction.



  The universal joint has a ring 1 on which the two journal crosses 2, 3 are rotatably arranged on both sides. The fists 6, 7 of the input and output shafts 8, 9 are guided through the recesses 4, 5 of the journal crosses 2, 3, the journals 10, 11 of which rest in the bearings 12, 13 of the associated journal crosses 2, 3. Inside the ring 1, the ball 14 is mounted at the end of the drive shaft 8 in a guide hollow cylinder 15 at the end of the output shaft 9.



  The lubricating head 16 on the ring 1 or on the shaft 9 is used for central lubrication of all bearing points of the joint via the channels k.
