The invention has the object of disclosing a straight guide for hypocycloids Actuator by the method described in the preamble of claim 1 type which allows not only a simple structure, a relatively free choice of the machine-side guide surfaces.

Zur Lösung dieser Aufgabe schlägt die Erfindung die Verwendung einer Watt'schen Geradführung mit einer mit dem Führungszapfen drehbeweglich verbundenen Kop pel der Watt'schen Führungslenker vor, wobei die Koppel im wesentlichen als Ring mit an Fortsetzen vorgesehenen Anlenkstellen für die Führungslenker gestaltet ist und die Führungslenker maschinen- und koppelseitig jeweils über Drehgelenke mit quer zur oszillierenden Schubstange gerichteten Achsen angeordnet sind. To achieve this object, the invention proposes the use of a Watt's straight guide with a rotatably connected to the guide pin Kop pel of the Watt's control arm before, the coupling is substantially shaped as a ring having provided on continuing articulation points for the guide link and the guide link machine and are arranged mutually coupled in each case via pivot joints with oscillating transversely to the push rod axis. Der Vor teil der Erfindung ist in einem einfachen Aufbau der Geradführung zu sehen sowie in der relativ freien Platzwahl der maschinenseitigen Führungsflächen, die vorzugs weise in einfachen Drehgelenken ausgebildet sind. Before the part of the invention can be seen in a simple construction of the linear guide and formed in the relatively free choice of seating on the machine side guide surfaces as preference in simple hinges. Im Sinne einer relativ freien Platzwahl sind die maschinenseitigen Drehgelenke der Führungslenker vom Hypo zykloiden-Hubgetriebe entfernt am Gehäuse der Hubkolbenmaschine anordbar. In the sense of a relatively free choice of the place machine side rotary joints of the guide rods are removed from the Hypo cycloidal Actuator the housing of the reciprocating piston can be disposed. Dies vereinfacht den Aufbau des Hubgetriebes und ermöglicht ferner eine kosten günstigere Gestaltung des Maschinengehäuses. This simplifies the structure of the lifting gear and also enables cost-effective design of the machine housing. Als tribologisch bewährtes Dreh gelenk kann z. may hinge as tribological proven rotation z. B. eine einfache Zapfen/Buchsen-Paarung vorgesehen werden. As a simple pin / socket pairing be provided.

Die Erfindung ist anhand eines in der Zeichnung schematisch dargestellten Aus führungsbeispiels beschrieben. The invention is described with reference to a schematically illustrated in the drawing for guiding example.

A running in Boxer type reciprocating piston engine 1 comprises diametrically in the cylinder liners 2, 2 'disposed pistons 3, 3', which share a common push rod. 4 In der Schubstange 4 ist mittig ein mit dem Hubzapfen 5 einer nicht gezeigten Kurbelwelle drehbeweglich verbunde ner Exzenter 6 eines Hypozykloiden-Hubgetriebe 7 drehge lagert. In the push rod 4, a rotational movement composites with the crankpins 5 of a crankshaft not shown ner eccentric 6 a hypocycloid Actuator 7 is centrally drehge superimposed. Dieser Exzenter 6 steht mit einem ebenfalls auf dem Hubzapfen 5 exzentrisch und drehbeweglich angeordne ten Führungszapfen 8 des Hypozykloiden-Hubgetriebes 7 einer zur oszillierenden Schubstange 4 orthogonal wirken den Geradführung 9 in drehfester Verbindung. This eccentric 6 is connected to a likewise eccentrically and rotationally movably arrange on the crank pin 5 th guide pin 8 of the hypocycloid-lifting gear 7 to an oscillating push rod 4 acting orthogonal to the straight guide 9 in a rotationally fixed connection.

Die Geradführung 9 ist als Watt'sche Geradführung 10 mit einer mit dem Führungszapfen 8 drehbeweglich verbundenen Koppel 11 der Watt'schen Führungslenker 12 , 12 ' ausge bildet.
