Description
Die Erfindung betrifft ein Getriebe für elektrische Fahrzeuge, bestehend aus einem Gehäuse (
Bekanntlich bestehen konventionelle Getriebe (
Allerdings müssen die oben genannten Getriebe Kupplungen eines bestimmten Aufbaus nutzen, die teuer und zudem schwer zu warten sind. Die Nutensteine und Druckplatten neigen zu schneller Abnutzung. Folglich bleiben die Druckplatten bei einem Schaltvorgang länger mit der Kupplung in Verbindung und die Zeit bis zur Geschwindigkeitsänderung verlängert sich. Das Gehäuse und die Druckplatten, die den Keilen zugerichtet sind, müssen in komplizierten Prozessen gefräst werden. Die damit verbundene Fräsdauer ist zu lang und somit unwirtschaftlich. Zudem ist der durch die Nutensteine resultierende Druck so hoch, dass die Nutensteine bei einer Geschwindigkeitsänderung nicht in ihre Ursprungsposition wechseln können. Dies kann zu einem Energieverlust bei jeder Geschwindigkeitsänderung führen.However, the above-mentioned gearboxes must use clutches of a particular construction that are expensive and also difficult to maintain. The sliding blocks and pressure plates tend to wear faster. As a result, the pressure plates remain in contact with the clutch longer during a shift and the time to speed change increases. The housing and the pressure plates, which are trimmed the wedges, must be milled in complicated processes. The associated milling time is too long and therefore uneconomical. In addition, the pressure resulting from the sliding blocks is so high that the sliding blocks can not change to their original position when the speed changes. This can lead to energy loss with any change in speed.
Aufgabe der Erfindung ist es ein Getriebe für elektrische Fahrzeuge zu konstruieren, das die oben genannten Mängel nicht aufweist.The object of the invention is to construct a transmission for electric vehicles, which does not have the above-mentioned defects.
Zur Lösung dieser Aufgabe schlägt das vorliegende Gebrauchsmuster ein optimiertes Getriebe zur Drehzahländerung für elektrische Fahrzeuge mit den Merkmalen der Ansprüche 1–9 vor.To solve this problem, the present utility proposes an optimized transmission for speed change for electric vehicles with the features of claims 1-9.
Das vorliegende Gebrauchsmuster bezieht sich auf ein Getriebe für elektrische Fahrzeuge und umfasst ein Gehäuse mit einer Antriebswelle, einer Übertragungswelle und einer Abtriebswelle. Zwischen der Antriebs-, Übertragungs- und Abtriebswelle sind mehrere Wechselgetriebestufen mit unterschiedlichen Übersetzungsverhältnissen angeordnet. Das Gehäuse ist mit einem Motor verbunden. Auf der Übertragungswelle sind die Wechselgetriebestufen mit Kupplungen verbunden. Eine Schaltvorrichtung und mehrere Antriebseinheiten sind mit der Übertragungswelle verbunden. Über den Antrieb des Motors werden die Antriebseinheiten über die Schaltvorrichtung nach rechts oder links zu einer Kupplung geführt, sodass sich die Übertragungswelle im Leerlauf befindet oder eine Drehzahl überträgt. Nur eine der Wechselgetriebestufen treibt die Übertragungswelle an und ändert deren Geschwindigkeit.The present utility model relates to a transmission for electric vehicles and includes a housing having a drive shaft, a transmission shaft and an output shaft. Between the drive, transmission and output shaft several change gear stages are arranged with different gear ratios. The housing is connected to a motor. On the transmission shaft, the change gear stages are connected to couplings. A Switching device and a plurality of drive units are connected to the transmission shaft. About the drive of the engine, the drive units are guided via the switching device to the right or left to a clutch, so that the transmission shaft is idling or transmits a speed. Only one of the change gear stages drives the transmission shaft and changes its speed.
Die vom Getriebe austretende Drehzahl ändert sich, indem die ein Schalter den Motor startet, der die Antriebsleistung durch die Außenverzahnung der Schaltvorrichtung an die Übertragungswelle leitet und damit Antriebseinheiten verschiebt, die kraftschlüssig in die Kupplungen greifen und die Wechselgetriebestufen aktiviert. Die Übertragungswelle wechselt die Drehzahl über die unterschiedlichen Übersetzungsverhältnisse der Wechselgetriebestufen des Getriebes. Die Drehzahländerung wird über die Abtriebswelle an die Fahrzeugräder weitergeleitet.The speed exiting the transmission changes by the one switch, the engine starts, which directs the drive power through the external toothing of the switching device to the transmission shaft and thus shifts drive units, which engage frictionally in the clutches and activates the gear change stages. The transmission shaft changes the speed over the different gear ratios of the gear change stages of the transmission. The speed change is transmitted via the output shaft to the vehicle wheels.
Das vorlegende Gebrauchsmuster wird noch verständlicher, wenn man die Beschreibung in Verbindung mit den beigefügten Zeichnungen betrachtet, die nur zu Demonstrationszwecken eine bevorzugte Ausführungsform, in Übereinstimmung mit dem vorliegenden Gebrauchsmuster, präsentieren.The present utility model will become more fully understood by considering the description in conjunction with the accompanying drawings which, for purposes of demonstration only, show a preferred embodiment in accordance with the present invention.
