Abstract
Hubkolben-Brennkraftmaschine mit einem über eine Kupplung, insbesondere eine Freilauf-Kupplung (8) mit der Maschinen-Kurbelwelle (1) verbindbaren Anlassermotor, wobei ein konzentrisch zur Kurbelwellen-Längsachse (1a) angeordneter Anlasserzahnkranz (5) das erste Kupplungsteil (8a) trägt und das zweite Kupplungsteil (8b) in einer mit der Kurbelwelle (1) verbundenen sowie die Verbindung mit einem an die Brennkraftmaschine angeflanschten Getriebe (3) herstellenden Mitnehmerscheibe (9) integriert ist, dadurch gekennzeichnet, dass der Anlasserzahnkranz (5) auf einem Abschlussdeckel (6) für das Brennkraftmaschinen-Kurbelgehäuse (2) drehbar gelagert ist.Reciprocating internal combustion engine with one over a clutch, in particular a freewheel clutch (8) with the engine crankshaft (1) connectable starter motor, wherein a concentric with the crankshaft longitudinal axis (1 a) arranged Starter ring gear (5) carries the first coupling part (8a) and the second coupling part (8b) in one with the crankshaft (1) connected and the connection with a flanged to the internal combustion engine Gear (3) producing drive plate (9) is integrated, characterized in that the starter ring gear (5) on a End cover (6) for the engine crankcase (2) is rotatably mounted.
Description
Die Erfindung betrifft eine Hubkolben-Brennkraftmaschine mit einem über eine Kupplung, insbesondere eine Freilauf-Kupplung mit der Maschinen-Kurbelwelle verbindbaren Anlassermotor.The The invention relates to a reciprocating internal combustion engine with a via a Coupling, in particular a freewheel coupling connectable with the engine crankshaft Starter motor.

der deutschen Offenlegungsschrift
Nachteilig an der beschriebenen Anordnung ist die für die Anordnung notwendige Baulänge der Kurbelwelle.adversely to the arrangement described is necessary for the arrangement overall length the crankshaft.
Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Anlassvorrichtung dahingehend zu verbessern, dass die Kurbelwelle kürzer baut.task The present invention is a generic starting device to improve so that the crankshaft builds shorter.
Diese Aufgabe ist durch das Merkmal im kennzeichnenden Teil des Patentanspruchs 1 gelöst.These The object is achieved by the feature in the characterizing part of the claim 1 solved.
Durch die erfindungsgemäße Ausgestaltung wird eine vereinfachte, kompakt bauende, sowie funktionell vorteilhafte Anlasseranordnung mit einer Kupplung, insbesondere einer Freilaufkupplung, an einer Hubkolben-Brennkraftmaschine aufzeigt. Mit der kompakten Anordnung baut die Kurbelwelle an ihrem Lagerende kürzer. Die kritische Kröpfung zwischen Hubzapfen und Endlager im Kurbelgehäuse, die besonders hohen mechanischen Belastungen ausgesetzt ist, wird nicht geschwächt. Somit wird eine äußerst steife Kurbelwelle erzielt. Darüber hinaus ist der Anlasser nicht im Ölraum angeordnet, wodurch ein von außen austauschbarer Zahnkranz erzielt wird, der im Servicefall einfach und problemlos zu wechseln ist.By the embodiment of the invention will a simplified, compact and functional advantageous Starter assembly with a clutch, in particular a one-way clutch, shows on a reciprocating internal combustion engine. With the compact Arrangement makes the crankshaft shorter at its bearing end. The critical bend between crankpin and end bearing in the crankcase, the particularly high mechanical Stress is not weakened. Thus, a very stiff Crankshaft achieved. About that addition, the starter is not located in the oil chamber, creating a from the outside replaceable ring gear is achieved, the easy in case of service and easy to change.
