Description

Die Erfindung betrifft einen Hubkolbenmotor mit einem von der Kurbelwelle ausgehenden Rädertrieb zu den Nockenwellen und Flüssigkeitspumpen des Motors nach dem Oberbegriff des Anspruchs 1.The invention relates to a reciprocating piston engine with a gear train emanating from the crankshaft to the camshafts and fluid pumps of the engine according to the preamble of claim 1.

Ein solcher Hubkolbenmotor ist aus DE-Z Sonderdruck ATZ, Automobiltechnische Zeitschrift, 71. Jahrgang, Nr. 9/12/1969 und 73. Jahrgang Nr. 5/1971 bekannt. Eine von der Kurbelwelle angetriebene Abtriebswelle zur Kupplung verläuft - in Höhenrichtung Fahrzeug gesehen - unterhalb der Kurbelwelle, zu ihr parallel. Sie wird von der Kurbelwelle über ein Zahnradgetriebe angetrieben, das in einer Mittelebene zwischen den beiden Kurbelwellenenden angeordnet ist. Die Abtriebswelle treibt ebenfalls über ein Zahnradgetriebe, die im Kurbelgehäuse des Motors angeordneten Ölpumpen an. Zur Stromversorgung des Motors dient eine Lichtmaschine, die oben am Motorgehäuse angeschraubt ist.Such a reciprocating piston engine is known from DE-Z Sonderdruck ATZ, Automobiltechnische Zeitschrift, 71st year, No. 9/12/1969 and 73rd year No. 5/1971. An output shaft driven by the crankshaft for the clutch runs - seen in the vertical direction of the vehicle - below the crankshaft, parallel to it. It is driven by the crankshaft via a gear transmission which is arranged in a central plane between the two crankshaft ends. The output shaft also drives the gear pumps and the oil pumps located in the engine crankcase. An alternator, which is screwed to the top of the engine housing, is used to power the engine.

Aufgabe der Erfindung ist es, einen Rädertrieb zu den Nockenwellen und den zur Schmierung und Kühlung des Motors benötigten Flüssigkeitspumpen so zu gestalten, daß die bei Drehzahländerungen am Motorgehäuse auftretenden Reaktionsmomente weitgehend ausgeglichen sind.The object of the invention is to design a gear train for the camshafts and the liquid pumps required for lubrication and cooling of the engine in such a way that the reaction torques occurring when the engine speed changes are largely balanced.

Eine Lösung dieser Aufgabe gelingt mit den kennzeichnenden Merkmalen des Anspruchs 1. Wenn die Abtriebswelle zur Kupplung im Gegensinn dreht wie die Kurbelwelle, die Nockenwellen und Flüssigkeitspumpen, vermindern sich die am Motor bei Drehzahländerungen wirksamen Gegenmomente zu den Antriebsmomenten. Auch die symmetrische Anordnung der Antriebsräder und Wellen zur V-Mitte begünstigt diesen erwünschten Momentenausgleich. Dieser Vorteil wird besonders spürbar bei Rennmotoren mit sehr hohen Maximaldrehzahlen von ca. 14000 1/min und raschen Drehzahländerungen des Motors.A solution to this problem is achieved with the characterizing features of claim 1. If the output shaft to the clutch rotates in the opposite direction to the crankshaft, the camshafts and liquid pumps, the counter-moments to the drive torques which are effective on the engine when the speed changes are reduced. The symmetrical arrangement of the drive wheels and shafts to the V center also favors this desired torque compensation. This advantage is particularly noticeable in racing engines with very high maximum engine speeds of approx. 14000 rpm and rapid engine speed changes.

In weiterer Ausgestaltung der Erfindung nach Anspruch 2 liegt der von der Kurbelwelle ausgehende Rädertrieb in einer Mittelebene zwischen den beiden Enden der Kurbelwelle. Es wird somit erreicht, daß die in den Rädertrieb eingehenden Drehschwingungsausschläge auf ein Mindestmaß reduziert sind. Denn die den größten Ausschlag ergebende Schwingungsform hat in der Mittelebene einen Knoten. Durch Wahl dieser ruhigen Zone für einen Mittenabtrieb bleiben die Kupplung-, die Nockenwellen- und Flüssigkeitspumpen weitgehend frei von Drehschwingungsausschlägen der Nockenwelle.In a further embodiment of the invention according to claim 2, the gear train originating from the crankshaft lies in a central plane between the two ends of the crankshaft. It is thus achieved that the torsional vibrations in the wheel drive are reduced to a minimum. Because the waveform that results in the greatest deflection has a knot in the middle plane. By choosing this quiet zone for a center drive, the clutch, camshaft and fluid pumps remain largely free of torsional vibrations of the camshaft.

Ein Hubkolbenmotor besitzt zwei V-förmig zueinander liegende Zylinderreihen 1 und 2 mit jeweils 6 Zylindern. In dem V-Ausschnitt 4 ist in V-Mitte 5 eine Lichtmaschine 6 angeordnet. Mit Laschen 7 ist sie an die Zylinderköpfe 8 angeschraubt.A reciprocating piston engine has two V-shaped cylinder rows 1 and 2, each with 6 cylinders. In the V-neck 4, an alternator 6 is arranged in the V-center 5. With tabs 7 it is screwed onto the cylinder heads 8.

An beiden Längsseiten des Kurbelgehäuses 9, das aus einem Unterteil 10 und einem Oberteil 11 zusammengesetzt ist, sind Flüssigkeitspumpen 12 angeordnet. Ein Pumpensatz der Flüssigkeitspumpen besteht jeweils aus einer Wasserpumpe 13, einer Ölsaugpumpe 14 und einer Öldruckpumpe 15. In den Zylinderköpfen 8 der beiden Zylinderreihen 1 und 2 sind jeweils zwei parallele Nockenwellen gelagert. Eine Einlaßnockenwelle 16 betätigt die Einlaßventile, eine Auslaßnockenwelle 17 die Auslaßventile. Zum Antrieb der Nockenwellen 16, 17 und der Flüssigkeitspumpen 12 dient ein Rädertrieb 18 aus miteinander kämmenden Stirnzahnrädern, der von einer Kurbelwelle 19 angetrieben ist. Der Rädertrieb 18 ist in einer Mittel ebene 20 des Motors angeordnet, die etwa mittig zwischen dem vorderen Ende 21 und dem hinteren Ende 22 der Kurbelwelle 19 quer zu ihr liegt.Liquid pumps 12 are arranged on both long sides of the crankcase 9, which is composed of a lower part 10 and an upper part 11. A pump set of the liquid pumps each consists of a water pump 13, an oil suction pump 14 and an oil pressure pump 15. Two parallel camshafts are each mounted in the cylinder heads 8 of the two cylinder rows 1 and 2. An intake camshaft 16 actuates the intake valves, an exhaust camshaft 17 the exhaust valves. To drive the camshafts 16, 17 and the liquid pumps 12, a gear drive 18 made of intermeshing spur gears is used, which is driven by a crankshaft 19. The wheel drive 18 is arranged in a central plane 20 of the engine, which lies approximately midway between the front end 21 and the rear end 22 of the crankshaft 19.

Die Kurbelwelle 19 treibt mit einem Zahnradpaar 23, 24 eine oberhalb zu ihr parallel liegende Abtriebswelle 25 an, die mit einer an der hinteren Stirnseite des Motors angeordneten Kupplung 26 verbunden ist. Ein Zahnrad 27 der Abtriebswelle 25 kämmt mit einem rechten Antriebsrad 28, mit dem die rechts der V-Mitte 5 liegenden Nockenwellen und Flüssigkeitspumpen angetrieben werden. Ein koaxiales weiteres Zahnrad 29 der Abtriebswelle 25 steht mit einem linken Antriebsrad 30 zum Antrieb der links der V-Mitte 5 angeordneten Nockenwellen und Flüssigkeitspumpen in Eingriff.The crankshaft 19 drives, with a pair of gearwheels 23, 24, an output shaft 25 which is parallel to it and which is connected to a clutch 26 arranged on the rear end of the engine. A gear 27 of the output shaft 25 meshes with a right drive wheel 28, with which the camshafts and liquid pumps located to the right of the V center 5 are driven. A coaxial additional gear 29 of the output shaft 25 is in engagement with a left drive wheel 30 for driving the camshafts and liquid pumps arranged on the left of the V center 5.

Beide Antriebsräder 28, 30 bestehen aus einem größeren mit dem Zahnrad 27 bzw. 29 der Abtriebswelle 25 kämmenden Antriebszahnrad 31 und einem kleineren Antriebszahnrad 32, mit dem die Nockenwellen 16, 17 und Flüssigkeitspumpen 12 angetrieben sind. Hierzu trägt die Einlaßnockenwelle ein Zahnrad 34 die Auslaßnockenwelle 17 ein Zahnrad 35, die beide gemeinsam über ein oberes Zwischenrad 33 von dem Antriebszahnrad 32 getrieben sind. Dasselbe Antriebszahnrad 32 kämmt mit einem unteren Zwischenrad 36, das ein Pumpenzahnrad 37 treibt, mit dem die Wasserpumpe 13, die Ölpumpe 14 und die Öldruckpumpe 15 gemeinsam angetrieben werden.Both drive wheels 28, 30 consist of a larger drive gear 31 meshing with the gear 27 and 29 of the output shaft 25 and a smaller drive gear 32, with which the camshafts 16, 17 and liquid pumps 12 are driven. For this purpose, the intake camshaft carries a gear 34, the exhaust camshaft 17 carries a gear 35, both of which are driven together by the drive gear 32 via an upper intermediate gear 33. The same drive gear 32 meshes with a lower intermediate gear 36, which drives a pump gear 37 with which the water pump 13, the oil pump 14 and the oil pressure pump 15 are driven together.

Die Lichtmaschine 6 wird mit einer Zwischenwelle 38, die koaxial und drehfest zu der Abtriebswelle 25 angeordnet ist und über einen von ihr ausgehenden Riementrieb 39 angetrieben. Der Riementrieb liegt zwischen der Vorderseite 40 des Motors und einer Querwand 41 des Fahrzeugaufbaus. Die Zwischenwelle 38 ist als dünner, federnder Drehstab ausgebildet, um Belastungsstöße im Antriebsstrang abzuschwächen.The alternator 6 is provided with an intermediate shaft 38 which is arranged coaxially and in a rotationally fixed manner with respect to the output shaft 25 and via one of the latter outgoing belt drive 39 driven. The belt drive lies between the front 40 of the engine and a transverse wall 41 of the vehicle body. The intermediate shaft 38 is designed as a thin, resilient torsion bar in order to weaken load impacts in the drive train.
