Abstract

A piston engine has symmetrical piston force distribution with two connecting rods (1,2) per piston (7) and two contra-rotating crankshafts (3,4) directly linked by gearwheels (5,6) directly mounted on the crankshaft.

Description

Die Erfindung betrifft eine Hubkolbenantriebsmaschine, insbesondere Hubkolben­ brennkraftmaschine mit symetrischer Kolbenkraftverteilung auf jeweils zwei Pleuel pro Kolben mit zwei sich zueinander gegensinnig drehenden, direkt kraft- und formschlüssig ineinander eingreifenden Kurbelwellen.The invention relates to a reciprocating piston drive machine, in particular reciprocating piston Internal combustion engine with symmetrical piston force distribution on two connecting rods each per piston with two counter-rotating, direct force and positively engaging crankshafts.

Sinn und Zweck der Erfindung ist es, bei Hubkolbenantriebsmaschinen mit Pleuel und Kurbelwelle, jene Kolbenseitenkräfte zu elemimieren, welche je nach Auslen­ kung des Pleuel in Bezug auf die Kurbelwelle und entsprechenden Druckverhält­ nissen im Brennraum auf die Zylinderwand wirken und somit Reibungsverluste und Verschleiß bedeuten.The purpose of the invention is for reciprocating piston drive machines with connecting rods and crankshaft to eliminate those piston side forces which, depending on the deflection the connecting rod in relation to the crankshaft and the corresponding pressure ratio nissen act on the cylinder wall in the combustion chamber and thus friction losses and Mean wear.

Die Lösung dieser Aufgabe gelingt erfindungsgemäß der eingangs genannten Art mit den kennzeichnenden Merkmalen des Patentanpruchs 1.This object is achieved according to the invention of the type mentioned at the outset with the characterizing features of patent claim 1.

Darüber hinaus ergibt sich durch die symetrische Kolbenkraftverteilung auf zwei Kurbelwellen aufgrund der verschobenen Symetrieachse des Zylinders zu den Kurbelwellenachsen, je nach Größe der Verschiebung eine Drehmomenterhöhung, resultierend aus den gegebenen Kraft- und Hebelverhältnissen von Pleuel und Kurbelwelle.In addition, the symmetrical distribution of piston forces results in two Crankshafts due to the shifted axis of symmetry of the cylinder Crankshaft axes, depending on the size of the displacement, an increase in torque, resulting from the given power and leverage ratios of connecting rods and Crankshaft.

Dem fertigungsseitigen Mehraufwand durch die doppelte Ausführung von Pleuel und Kurbelwelle steht gegenüber ein geringerer Kolben-/Zylinderverschleiß, Dreh­ momenterhöhung und Kraftstoffersparnis.The additional manufacturing effort due to the double design of connecting rods and crankshaft stands against a lower piston / cylinder wear, rotation torque increase and fuel savings.

In Fig. 1 ist die Anbindung der Pleuel 1 und 2 an den Kolben 7 zentrisch einachsig dargestellt, wobei die Kolbenkraftverteilung symetrisch auf die Pleuel 1 und 2, und fortführend auf die sich gegensinnig drehenden Kurbelwellen 3 und 4 erfolgt, welche kraft- und formschlüssig mit auf der Kurbelwellenachse sitzenden Zahnrädern 5 und 6 verbunden, resultierend ineinander eingreifend, ein gemeinsames Drehmoment auf den Antrieb bewirken. Fig. 2 stellt eine symetrische zweiachsige Anbindung der Pleuel 1 und 2 an den Kolben 7 dar.In Fig. 1 the connection of the connecting rods 1 and 2 to the piston 7 is shown centrically uniaxially, the piston force distribution symmetrically on the connecting rods 1 and 2 , and continuing on the counter-rotating crankshafts 3 and 4 , which is non-positive and positive connected on the crankshaft axis gears 5 and 6 , resulting meshing, causing a common torque on the drive. Fig. 2 shows a symmetrical two-axis connection of the connecting rods 1 and 2 to the piston 7 .
