Dabei ist die Kurbelwelle entweder ohne Mittellager zwischen den beiden Kurbelzapfen einteilig oder mit Mittellager mehrteilig ausgebildet. Wegen der weitgehend in einer Drehrichtung drehenden Massen der Maschine tritt auch ein erhebliches Rückdrehmoment um die Längsachse der Maschine bei Drehzahländerungen auf.Known internal combustion engines of this type according to Z-DE "Das Motorrad", issue 14/1974, p. 16 and issue 24/1980, p. 28 and 30 as well as Z-DE "PS", issue 2 / 1.981, pp. 5 to 8 show a very small longitudinal offset of the cylinders, which results from this the resulting mass torques around the vertical axis of the machines to be kept low. The crankshaft is either Without a central bearing between the two crank pins in one piece or in several parts with a central bearing. Because the largely rotating masses in one direction of rotation Machine, there is also a significant back torque around the longitudinal axis of the machine when the speed changes.
Aufgabe der Erfindung ist es, die Massendrehmomente und Rückdrehmonente mittels einer Ausgleichsvorrichtung bei geringem zusätzlichen Bauaufwand und Raumbedarf zumindest weitgehend zu beseitigen.The object of the invention is to reduce the mass torques and reverse torque by means of a compensation device to eliminate at least largely little additional construction costs and space requirements.

Fig. 3 die schematische Stirnansicht des Boxermotors nach den Fig. 1 und 2.3 shows the schematic end view of the boxer engine according to FIGS. 1 and 2.
Ein Zweizylinder-Viertakt-Boxermotor für Motorräder weist gemäß Fig. 1 u. 3 ein Motorgehäuse 1, zwei einander gegenüberliegende Zylinder 2 und diesen zugeordnete Zylinderköpfe auf. Im Gehäuse 1 ist eine Kurbelwelle 4 in drei Lagern 5 drehbar gelagert. Die Kurbelwelle U weist zwei Kurbelzapfen 6 auf, die um i80°-Kurbelwinkel gegeneinander verdreht angeordnet und je einem in den Zylindern 2 geführten Kolben 7 über Pleuel δ zugeordnet sind. Den Kurbelzapfen 61 and 3, a two-cylinder four-stroke boxer engine for motorcycles has an engine housing 1, two opposing cylinders 2 and cylinder heads assigned to them. A crankshaft 4 is rotatably supported in three bearings 5 in the housing 1. The crankshaft U has two crank pins 6, which are arranged rotated by 180 ° crank angle relative to one another and are each assigned to a piston 7 guided in the cylinders 2 via connecting rods δ. The crank pin 6
gegenüberliegend ist an der Kurbelwelle 4 je ein Paar Kurbelwellen-Gegengewichte 9 befestigt. Entsprechend dem Abstand der Kurbelzapfen 6 in Längsrichtung der Kurbelwelle 4 sind auch die beiden Zylinder 2 in gleicher Richtung gegeneinander versetzt. Die Kurbelwelle 4 trägt an ihrem abtriebsseitigen Ende ein Schwungrad 10 und am anderen Ende ein Zahnrad 11 zum Antrieb einer Zwischenwelle 12 und weiterer Aggregate. Die Zwischenwelle 12 ist parallel zur j· Kurbelwelle 4 in geringem Abstand über dieser in zwei La-opposite a pair of crankshaft counterweights 9 is attached to the crankshaft 4. Corresponding to the distance between the crank pins 6 in the longitudinal direction of the crankshaft 4, the two cylinders 2 are also offset from one another in the same direction. The crankshaft 4 carries a flywheel 10 at its output end and a gear 11 at the other end for driving an intermediate shaft 12 and other units. The intermediate shaft 12 is parallel to the j · crankshaft 4 at a short distance above this in two laser
2Q gern 13 gelagert. Neben einem Zahnrad 14 für den Eingriff in das kurbelwellenseitige· Zahnrad 11 sind auf dem einen Ende der Zwischenwelle 12 ein Entlüftungsdrehschieber 15 für die gesteuerte Entlüftung des Motorgehäuse-Inneren und ein Riemenrad 16 für einen Keil- oder Zahnriementrieb 17 zu einem Generator 18 angeordnet. Zwischen den Lagern 13 trägt die Zwischenwelle 12 etwa mittig ein Antriebszahnrad oder Schraubenzahnrad 19 für eine Antriebswelle einer nicht dargestellten Zünd-Vorrichtung und ggf. einer ebenfalls nicht dargestellten Ölpumpe. In den beiden von den Mittelachsen der Zylinder 2 bestimmten Querebenen 20 trägt die Zwischenwelle 12 je ein Ausgleichs-Gegengewicht 21, die mit den Kurbelwellen-Gegengewichten 9 übereinstimmende, einander zu- und abgewandte Extremdrehlagen aufweisen. Im Bereich der einander zugewandten Drehlagenstellungen der Gegengewichte 9 und 21 überlappen sich die beiden Kreisbahnen derselben, so daß jeweils ein Ausgleichs-Gegengewicht 21 zwischen das zugeordnete Paar der Kurbelwellen-Gegengewichte 9 eingreift. Die Zwischenwelle 12 trägt ferner an einem freien Ende ein Zahnritz.el 22 für einen Kettentrieb 23 zu einer weiteren Zwischenwelle 24, die ein zur 1 : 2-übersetzung größeres Zahnrad 25 für den Kettentrieb 23 und zwei weitere Zahnräder 26 für je einen 1 : 1-Zahnriementrieb 27 zu den Zylinderköpfen 3 trägt. Die Kurbelwelle 4 und beide Zwischenwellen 12 und 24 sind in einer»' Teilungsebene 1f des Motorgehäuses 1 gelagert, die in der senkrechten Längsmittelebene des Motors angeordnet ist.2Q like 13 stored. In addition to a gear 14 for engaging the crankshaft-side gear 11, a rotary vent valve 15 for the controlled venting of the inside of the motor housing and a belt wheel 16 for a V-belt or toothed belt drive 17 to a generator 18 are arranged on one end of the intermediate shaft 12. Between the bearings 13, the intermediate shaft 12 carries a drive gear or helical gear 19 approximately in the middle for a drive shaft of an ignition device (not shown) and possibly an oil pump (also not shown). In the two transverse planes 20 determined by the central axes of the cylinder 2, the intermediate shaft 12 each carries a balancing counterweight 21, which has extreme rotational positions that correspond to the crankshaft counterweights 9 and face one another. In the area of the mutually facing rotational position positions of the counterweights 9 and 21, the two circular paths of the counterweights overlap, so that in each case a compensating counterweight 21 engages between the associated pair of crankshaft counterweights 9. The intermediate shaft 12 also carries a Zahnritz.el 22 for a chain drive 23 to a further intermediate shaft 24, which has a larger gear 25 for the 1: 2 ratio for the chain drive 23 and two further gears 26 each for a 1: 1 -Toothed belt drive 27 to the cylinder heads 3 carries. The crankshaft 4 and both intermediate shafts 12 and 24 are mounted in a '' division plane 1 f of the engine housing 1, which is arranged in the vertical longitudinal center plane of the engine.
An den Zylinderkopfen 3 ist je ein weiteres Zahnrad 28 für die Zahnrienentriebe 27 an je einer Nockenwelle 29 befestigt, die die Ventile 30 in den Zylinderkopfen 3 steuern.On the cylinder head 3 is a further gear 28 for the toothed belt drives 27 each attached to a camshaft 29 which control the valves 30 in the cylinder head 3.
r Sowohl durch die enge Zuordnung der Kurbelwelle A und der Zwischenwelle 1? zueinander als auch durch die relativ kleinen Zahnräder 28 an den Nockenwellen 29 aufgrund der 1 : 1-Zahnriementriebe 27 weist der Gesamtaufbau des Motors einen geringen Raumbedarf auf. Die Gegengewichte auf der Zwischenwelle 12 gleichenc.ie Massendrehmomente aus der Ausbildung der Kurbelwelle M aus und tragen zugleich aufgrund des Gegendrehsinnes zur Kurbelwelle k zusammen mit v/eiteren im gleichen Drehsinn angetriebenen Aggregaten, wie Generator 18, weitere Zwischenwelle 24 und Nockenwellen .v sowie deren sämtliche Antriebs-Zahnräder 25, 26 und 28, zum Ausgleich des bei Drehzahländerungen auftretenden Gegendrehmomentes bei.r Both through the close association of crankshaft A and intermediate shaft 1? to each other and due to the relatively small gears 28 on the camshafts 29 due to the 1: 1 toothed belt drives 27, the overall structure of the engine requires little space. The counterweights on the intermediate shaft 12 equalize the mass torques from the formation of the crankshaft M and at the same time, due to the opposite direction of rotation to the crankshaft k, together with other units driven in the same direction of rotation, such as generator 18, further intermediate shaft 24 and camshafts . v and all of their drive gears 25, 26 and 28, to compensate for the counter-torque that occurs when the speed changes.
Bei der Abwandlung nach Fig. 2 ist eine Abtriebskupplung O0 110 an der Zwischenwelle 112 angeordnet. Dadurch ist zusätzlich zu der Ausbildung nach Fig. 1 einerseits der Anteil der drehenden Massen der Kurbelwelle 4 verringert und andererseits der Anteil der im Gegendrehsinn zur Kurbelwelle drehenden Massen um die Abtriebskupplung vergrößert. Der Ausgleich der Gegendrehmomente bei Drehzahländerungen ist auf diese Weise ohne zusätzlichen Bauaufwand weiter erhöht.In the modification according to FIG. 2, an output clutch O 0 110 is arranged on the intermediate shaft 112. As a result, in addition to the embodiment according to FIG. 1, on the one hand the proportion of the rotating masses of the crankshaft 4 is reduced and, on the other hand, the proportion of the masses rotating in the opposite direction to the crankshaft around the output clutch is increased. The compensation of the counter torques in the event of speed changes is further increased in this way without additional construction costs.
