Die Nabe eines treibenden Elementes, Zahn-, Kettenrad oder Riemenscheibe, ist auf der Kurbelwelle drehfest angeordnet. Die Außenfläche der Nabe bildet die Kon taktfläche für den im Gehäuseverschlußdeckel gelagerten Dichtring. Am treibenden Element ist das Geberrad mit ringförmig axial nach dem Gehäuseverschlußdeckel gerichteten Stegen befestigt. Zusätzlich weist das treibende Element einen Ringsteg auf, der außen einen Ringsteg am Gehäuseverschlußdeckel überdeckend ein ein faches Labyrinth bildet. Innerhalb beider Ringstege liegt Dichtring, Geberrad und Drehzahlgeber umschlossen und damit geschützt.The hub of a driving element, toothed, sprocket or pulley, is arranged on the crankshaft in a rotationally fixed manner. The outer surface of the hub forms the con tact area for the sealing ring mounted in the housing cover.

Vorbekannt ist es, z. B. durch die Schriften DE 38 09 904 A1; EP 0 438 624 A1, daß Abdichtanordnungen am Kugelumlaufraum von Wälzlagern benachbart angeordnet sind und einen an der abzudichtenden Welle festen Laufring für die Dichtlippen des Dichtringes aufweisen. Dieser Laufring bildet gleichzeitig eine Geberscheibe mittels eines radialen scheibenförmigen Ansatzes für einen Drehzahlgeber.It is previously known, for. B. by the documents DE 38 09 904 A1; EP 0 438 624 A1 that Sealing arrangements on the ball circulation space of roller bearings arranged adjacent are and a race on the shaft to be sealed for the sealing lips of the Have sealing ring. At the same time, this race forms an encoder disk a radial disk-shaped approach for a speed sensor.
Der Erfindung liegt die Aufgabe zugrunde, bei einem eingangs genannten Gehäuse verschlußdeckel eine schützende Abdeckung des Dichtringes und der Geberscheibe zu erzielen, wobei jedoch der Drehzahlgeber ohne Beeinträchtigung der Dichtanordnung gut demontierbar sowie genau positionierbar sein soll.The invention has for its object in a housing mentioned in the introduction sealing cover a protective cover of the sealing ring and the encoder disc to achieve, however, the speed sensor without affecting the sealing arrangement should be easy to disassemble and position exactly.
Erfindungsgemäß wird dies durch die im kennzeichnenden Teil des Hauptanspruches genannten Merkmale erzielt.According to the invention this is characterized in the characterizing part of the main claim achieved characteristics.
An Hand von Zeichnungen soll die Erfindung näher erläutert werden.The invention will be explained in more detail with reference to drawings.
Es zeigt:It shows:
Fig. 1 eine Vorderansicht des Gehäuseverschlußdeckels, Fig. 1 is a front view of the housing sealing cover,
Fig. 2 einen Schnitt A-A gemäß Fig. 1, Fig. 2 shows a section AA according to FIG. 1,
Fig. 3 einen Teilschnitt eines Geberrades. Fig. 3 shows a partial section of a transmitter wheel.
Aus Fig. 1 sind der Verschlußdeckel 1 - im vorliegenden Beispiel als Gußteil ausgeführt - die ange gossene Rippe 1.1, der Geber 2, das Geberrad 3, der Dichtring 4 und die Kurbelwelle 6 ersichtlich, dabei bilden Verschlußdeckel 1 zusammen mit dem Geber 2, dem Geberrad 3 und dem Dichtring 4 eine bauliche Einheit, welche kurze Montagezeiten zuläßt. Hierbei liegen der Geber 2, das Geber rad 3 und der Dichtring 4 annähernd in der gleichen Ebene wie aus Fig. 2 erkennbar ist. Zur Lage fixierung des Gebers 2 dienen die in der Rippe 1.1 eingebrachten Flächen 1.11, wobei diese so eingebracht sind, daß der Geber 2 genau in der X-, Y- und Z-Richtung fixiert ist, dabei sind keine zusätzlichen Bauteile notwendig. Darüber hinaus erfüllt die Rippe 1.1 auch noch die Aufgabe, einen Schutz gegen Verschmutzung für den Geber 2 zu gewähren und ist aus diesem Grunde vorzugsweise konisch ausgeführt. Diese gleiche Aufgabe fällt auch dem am Geberrad 3 angebrachten Radius 3.4 zu, wie Fig. 3 zeigt. Damit der Drehzahlgeber 2 an der Wandung des Gehäuseverschlußdeckels 1 flächig voll anliegt, ist diese an dieser Stelle plan, wie auch Fig. 2 erkennen läßt. Ein oder mehrere z. B. Halte knöpfe bzw. Schnapphaken 2. 1 halten den Geber 2 am Gehäuseverschlußdeckel 1 fest, so daß dieser zerstörungsfrei lösbar befestigt ist.From Fig. 1, the cover 1 - executed in the present example as a casting - the cast rib 1.1 , the encoder 2 , the encoder wheel 3 , the sealing ring 4 and the crankshaft 6 can be seen, thereby forming the cap 1 together with the encoder 2 , the The encoder wheel 3 and the sealing ring 4 form a structural unit which allows short assembly times. Here are the encoder 2 , the encoder wheel 3 and the sealing ring 4 approximately in the same plane as can be seen from Fig. 2. The surfaces 1.11 introduced in the rib 1.1 serve to fix the position of the encoder 2 , these being introduced in such a way that the encoder 2 is fixed exactly in the X, Y and Z directions, no additional components being necessary. In addition, the rib 1.1 also fulfills the task of providing protection against contamination for the transmitter 2 and is therefore preferably conical. This same task also applies to the radius 3.4 attached to the sensor wheel 3 , as shown in FIG. 3. So that the speed sensor 2 lies flat against the wall of the housing cover 1, it is flat at this point, as can also be seen in FIG. 2. One or more z. B. Hold buttons or snap hooks 2 . 1 hold the encoder 2 on the housing cover 1 so that it is detachably attached non-destructively.
Aus Fig. 2 ist noch erkenntlich, ein am Verschlußdeckel 1 vorhandener Dichtflansch 1.2, welcher einerseits den Dichtring 4 trägt und andererseits ebenfalls zum Schutz des Dichtringes 4 dient. Da bei ist der Dichtring 4 in an sich bekannter Weise am Dichtflansch 1.2 anvulkanisiert. Weiterhin ist die statische Dichtlippe 5 als Spaltdichtung zwischen Motorgehäuse und Verschlußdeckel 1 wirkend, in ebenfalls an sich bekannter Weise an der Rückseite des Dichtflansches 1.2 anvulkanisiert. Des wei teren zeigt Fig. 2 das Geberrad 3, welches mit seinem U-inneren Schenkel 3.2 auf die Kurbelwelle 6 aufgepreßt ist. Der U-äußere Schenkel 3.1 ist mit Zähnen bzw. Segmentfeldern 3.3 versehen, wobei ein Zahn bzw. Segmentfeld 3.3 zur OT-Bestimmung breiter ausgelegt ist. Diesem gegenüberliegend ist eine Aussparung oder Bohrung 3.5 als Masseausgleich zum verbreiterten Feld 3.3 und als zusätz liche Fixierung zum OT eingebracht. Der innere U-Schenkel 3.2 dient gleichzeitig als Lauffläche für die Lippe des Dichtringes 4 und als statische Abdichtung gegenüber der Kurbelwelle 6, dabei ist dieser Schenkel 3.2 mit einem Elastomerteil überzogen. Darüber hinaus fixieren das Geberrad 3 in Verbin dung mit dem Verschlußdeckel 1, insbesondere dessen Dichtflansch 1.2, die Laufspur des dynami schen Dichtringes 4. Eine Leitung 2.2 verbindet den Drehzahlgeber 2 mit dem nicht dargestellten Bordcomputer.From FIG. 2 it can also be seen that there is a sealing flange 1.2 on the sealing cover 1 , which on the one hand carries the sealing ring 4 and on the other hand also serves to protect the sealing ring 4 . Since the sealing ring 4 is vulcanized in a known manner on the sealing flange 1.2 . Furthermore, the static sealing lip 5 acts as a gap seal between the motor housing and the closure cover 1 , also vulcanized in a manner known per se on the back of the sealing flange 1.2 . Furthermore, Fig. 2 shows the encoder wheel 3 , which is pressed onto the crankshaft 6 with its U-inner leg 3.2 . The U-outer leg 3.1 is provided with teeth or segment fields 3.3 , a tooth or segment field 3.3 being designed to be wider for TDC determination. Opposite this, a recess or hole 3.5 is introduced as a mass balance to the widened field 3.3 and as an additional fixation to the OT. The inner U-leg 3.2 serves simultaneously as a running surface for the lip of the sealing ring 4 and as a static seal with respect to the crankshaft 6 , this leg 3.2 being covered with an elastomer part. In addition, fix the encoder wheel 3 in connec tion with the cover 1 , in particular the sealing flange 1.2 , the track of the dynamic sealing ring 4th A line 2.2 connects the speed sensor 2 to the on-board computer, not shown.
