Description

Die Erfindung betrifft einen Dreizylinder-Motor und dessen Anordnung in einspurigen Fahrzeugen, insbesondere Krafträdern. Es ist üblich, die Triebwerke in Krafträdern mit der Kurbelwellenmittellinie quer zur Fahrtrichtung unterzubringen. Diese Bauweise hat sich an Ein- und Zweizylinderbrennkraftmaschinen bewährt. Eine Dreizylindermaschine auf die gleiche Art unterzubringen erfordert eine zu große Baubreite und verhindert zudem eine günstige Kühlluftführung für die Zylinder.The invention relates to a three-cylinder engine and its arrangement in single-track vehicles, especially motorcycles. It is common to use the thrusters in motorcycles with the crankshaft center line transverse to the direction of travel. This design has proven itself on single and two-cylinder internal combustion engines. One To accommodate a three-cylinder machine in the same way requires too large a machine Overall width and also prevents favorable cooling air routing for the cylinders.

Aufgabe der Erfindung ist es, eine Dreizylinderbrennkraftmaschine zu schaffen, die bei geringer Baubreite eine gute Zuführung der Kühlluft an die Zylinder zuläßt.The object of the invention is to provide a three-cylinder internal combustion engine to create a good supply of cooling air to the with a small overall width Cylinder allows.

Das schafft die Erfindung dadurch, daß an einem Dreizylinder-Motor, dessen in drei verschiedenen, zur Kurbelwelle senkrechten Ebenen angeordnete Zylinder auf dieselbe Kurbelwelle arbeiten, die beiden äußeren Zylinder in Reihe angeordnet sind, während der mittlere Zylinder dazu versetzt ist. Die Versetzung dabei ist zweckmäßig kleiner als ein rechter Winkel, und zwar z. B. 75°. Der mittlere Zylinder trägt vorzugsweise Längskühlrippen und ragt etwa waagerecht nach vorn, während die beiden äußeren Zylinder, mit Querkühlrippen versehen, nach oben ragen. Die Lage der Zylinder gibt die Möglichkeit, einen für alle drei gemeinsam arbeitenden Vergaser anzubringen, von dem etwa gleich lange Ansaugleitungen zu den Zylindern führen.This creates the invention in that on a three-cylinder engine, its cylinders arranged in three different planes perpendicular to the crankshaft work on the same crankshaft, the two outer cylinders arranged in series while the middle cylinder is offset to it. The transfer is there appropriately smaller than a right angle, namely z. B. 75 °. The middle cylinder preferably carries longitudinal cooling fins and protrudes approximately horizontally forwards, while the both outer cylinders, provided with transverse cooling fins, protrude upwards. The location the cylinder gives the option of a carburetor that works together for all three to be attached, from which suction lines of about the same length lead to the cylinders.

Fig. i zeigt als Beispiel die Seitenansicht eines Kraftrades, Fig.2 und 3 die Seitenansicht und die Draufsicht aus Fahrtrichtung seines Dreizylinder-Motor-Getriebeblockes.Fig. I shows as an example the side view of a motorcycle, Fig.2 and FIG. 3 shows the side view and the top view from the direction of travel of its three-cylinder engine transmission block.

An ein gemeinsames Motorgetriebegehäuse i sind die drei Zylinder 2, 2' und 3 angeflanscht. Der Winkel zwischen den äußeren (:2,:2') und dem horizontal liegenden mittleren Zylinder 3 beträgt 75o. Die Kühlrippen sind der Richtung des Fahrtwindes angeglichen. Der Zylinderkopf 4 ist sternförmig verrippt, so daß er die anströmende Luft gleichmäßig auf die Längsverrippung 5 des Zylinderkörpers verteilt. Die äußeren Zylinder 2 und 2 sind in bekannter Weise leicht gegen die Fahrtrichtung geneigt, wodurch die in Fahrtrichtung verrippten Köpfe 6 und die Ouerverrippung 7 der Zylinderkörper kühlungsgünstig im Luftstrom zu liegen kommen. Der Vergaser 8 ist gegen Kaltluft geschützt zwischen den Zylindern 2 und 2' angebracht. Die Ansaugleitungen lassen sich zur Erzielung gleicher Füllungsverhältnisse für alle drei Zylinder etwa gleich lang ausführen.The three cylinders 2, 2 'and 3 flanged. The angle between the outer (: 2,: 2 ') and the horizontal lying middle cylinder 3 is 75o. The cooling fins are in the direction of the Adjusted airflow. The cylinder head 4 is ribbed in a star shape so that it the incoming air is evenly distributed over the longitudinal ribs 5 of the cylinder body. The outer cylinders 2 and 2 are in a known manner slightly against the direction of travel inclined, as a result of which the heads 6 and the Ouerverrippung ribbed in the direction of travel 7 the cylinder body come to lie in the air stream in a way that is favorable for cooling. The carburetor 8 is protected against cold air between the cylinders 2 and 2 '. The suction lines can be used to achieve the same filling ratios for all three cylinders carry out the same length.
