Abstract
Description
Das Verstellgetriebe für die relative Drehwinkelverstellung ist eine Vorrichtung zum stufenlosen Variieren des Drehwinkels eines getriebenen Gliedes zu einem treibenden Glied. Insbesondere bezieht sich die Erfindung auf eine solche Vorrichtung, die in der Lage ist, den Drehwinkel der Nockenwelle relativ zur Antriebsscheibe bzw. zum Antriebsrad während des Betriebs eines Verbrennungsmotors zu variieren.The relative rotational angle adjustment mechanism is a device for continuously varying the rotational angle of a driven member to a driving member. In particular, the invention relates to such a device which is able to vary the angle of rotation of the camshaft relative to the drive pulley or to the drive wheel during the operation of an internal combustion engine.
Wie wohlbekannt ist, hat die relative Drehwinkelverstellung der Einlass- bzw. Auslass-Nockenwelle zu einem jeweiligen Antriebsrad einen beachtlichen Effekt auf die Motorleistungssteigerung und die Abgasreduzierung. Um die Leistung unter verschiedenen Betriebsbedingungen zu optimieren, ist es notwendig, die Drehwinkelverstellung zwischen Nockenwelle und Kurbelwelle eines Verbrennungsmotors zu variieren. Ein Problem, dem in einem solchen Mechanismus Rechnung getragen werden muss, liegt in der Art und Weise, wie die stufenlose Drehwinkelverstellung bei laufendem Motor zu steuern ist.As is well known, the relative rotational angle adjustment of the intake or exhaust camshaft to a respective drive wheel has a significant effect on engine performance and exhaust reduction. In order to optimize the performance under different operating conditions, it is necessary to vary the rotational angle adjustment between the camshaft and crankshaft of an internal combustion engine. One problem that must be addressed in such a mechanism is the way in which stepless rotation angle adjustment is to be controlled while the engine is running.
In der Vergangenheit wurden verschiedene variable Drehwinkelverstellvorrichtungen vorgeschlagen. Die Realisierung in der Großserie wurde allerdings verhindert oder eingeschränkt. Gründe hierfür sind der großer Raumbedarf sowie hohe Fertigungskosten. Ebenso mangelnde Zuverlässigkeit.Various variable rotational angle adjustment devices have been proposed in the past. However, the realization in mass production was prevented or restricted. The reasons for this are the large space requirement and high production costs. Similarly, lack of reliability.
Die vorliegende Erfindung hat zum Ziel, eine besonders kompakte und wirksame Form der relativen Drehwinkelverstellung zu schaffen, die auf einfache Weise gesteuert werden kann. Da das Stellglied bei laufendem Motor nicht mitrotiert sondern nur noch um den gewünschten relativen Drehwinkel entsprechend gedreht wird, kann man diese Erfindung leichter in bestehende Motorenkonzepte integrieren.The object of the present invention is to provide a particularly compact and effective form of relative rotational angle adjustment which can be easily controlled. Since the actuator is not rotated with the engine running but only rotated by the desired relative rotation angle accordingly, this invention can be more easily integrated into existing engine concepts.
