Description
Die vorliegende Erfindung betrifft einen Antriebsstrang für ein Kraftfahrzeug gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a power train for a motor vehicle according to the generic term of claim 1
Heutzutage werden in Kraftfahrzeugen als Antriebsquelle keine Gasturbinen eingesetzt. Der Grund liegt darin, dass die hohen Drehzahlen einer Gasturbine nicht auf in PKW gewünschte Drehzahlen zwischen etwa Null und 9000 U/min gebracht werden können. Ein weiteres Problem besteht darin, dass die Verzahnungen für diese Drehzahlen in der Regel geräusch- und festigkeitsmäßig nicht geeignet sind.nowadays Be used in motor vehicles as a source of power no gas turbines. The reason is that the high speeds of a gas turbine not on in car desired Speeds between about zero and 9000 rpm can be brought. One Another problem is that the gears for this Speeds are generally noisy and not in terms of strength are suitable.
Der vorliegende Erfindung liegt die Aufgabe zugrunde, einen Antriebsstrang für ein Kraftfahrzeug anzugeben, welcher als Antriebsquelle eine Gasturbine enthält.Of the The present invention is based on the object, a drive train for a Specify motor vehicle, which as a drive source, a gas turbine contains.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is solved by the features of claim 1. Further Embodiments and advantages will become apparent from the dependent claims.
Demnach wird ein Antriebsstrang für ein Kraftfahrzeug vorgeschlagen, der eine Gasturbine mit einem nachgeschaltetem Stufenlos-Getriebe umfasst.Therefore will be a powertrain for proposed a motor vehicle, a gas turbine with a downstream Continuously variable transmission covers.
Im Rahmen einer vorteilhaften Ausführungsform der vorliegenden Erfindung ist das der Gasturbine nachgeschaltete Stufenlos-Getriebe als Toroid-Getriebe mit stufenlos verstellbaren Reibradvariatoren, welche mindestens zwei Torusscheiben mit toroidförmigen Laufflächen aufweisen, zwischen denen Rollkörper abrollen, ausgeführt. Durch die hohen Drehzahlen sind die zu übertragenden Momente entspre chend klein, so dass die Variatoren in der Regel kompakt gehalten werden können. Die Toroid-Variatoren können mit nachgeschalteten reib- und/oder formschlüssigen Übersetzungs-Stufen geschaltet werden. Toroid-Variatoren sind für hohe Eingangsdrehzahlen geeignet; beispielsweise können verstellbaren Turboladern nachgeschaltete Toroid-Variatoren für Drehzahlen bis jenseits der 100.000 U/min ausgelegt werden.in the Frame of an advantageous embodiment The present invention is that of the gas turbine downstream Continuously variable transmission as a toroidal transmission with infinitely adjustable Friction wheel variators, which have at least two torus disks with toroidal running surfaces, between those rolling bodies unroll, executed. Due to the high speeds are the moments to be transmitted accordingly small, so the variators are usually kept compact can. The toroid variators can be connected with downstream friction and / or positive translation stages. Toroid variators are for high input speeds suitable; for example, can be adjustable Turbochargers downstream toroidal variators for speeds beyond the 100,000 rpm are designed.
Eine besonders vorteilhafte Ausführungsform sieht vor, dass das nachgeschaltete Getriebe eine Geared-Neutral-Charakteristik aufweist und somit endliche Antriebsdrehzahlen bei stillstehendem Abtrieb ermöglicht. Dadurch entsteht der Vorteil, dass die Drehzahlen beliebig klein gewandelt werden können. Auch in diesem Fall hier kann dem Getriebe, vorzugsweise dem Toroid-Getriebe, eine reib- und/oder formschlüssige Übersetzungsstufe nachgeschaltet werden, wobei diese beim Geared-Neutral-Getriebe nicht notwendig ist.A particularly advantageous embodiment provides that the downstream transmission has a geared-neutral characteristic and thus finite drive speeds with stationary output allows. This creates the advantage that the speeds are arbitrarily small can be converted. Also in this case, the transmission, preferably the toroidal transmission, a friction and / or positive translation stage be followed, this with the geared-neutral gear is not necessary.
Je höher die rezyklierende Leistung im Variator nahe dem Geared-Neutral-Punkt ausfällt, umso höher ist die Momentenbelastung im Variator. Es kann somit ein optimaler Kompromiss zwischen einfach gehaltenem Getriebesystem und Baugröße des Variators erzielt werden.ever higher the recycling performance in the variator near the geared neutral point fails, the higher is the moment load in the variator. It can thus be an optimal one Compromise between simply held transmission system and size of the variator be achieved.
Zudem kann durch die Realisierung einer Geared – Neutral – Charakteristik die Notwendigkeit eines zusätzlichen Rückwärtsganges entfallen, da die Verstellung des stufenlosen Getriebes die Umschaltung zwischen Vorwärts- und Rückwärtsgang übernimmt.moreover By implementing a geared - neutral characteristic the necessity of a additional reverse gear omitted, since the adjustment of the continuously variable transmission switching between forward and reverse gear takes over.
Durch die erfindungsgemäße Konzeption werden die Vorteile einer Gasturbine, insbesondere die hohe Leistungs dichte mit den beschriebenen Vorteilen eines Stufenlos-Getriebes kombiniert.By the conception according to the invention the advantages of a gas turbine, in particular the high power density combined with the described advantages of a continuously variable transmission.
Selbstverständlich fällt auch jede konstruktive Ausbildung, soweit technisch sinnvoll, unter den Schutzumfang der vorliegenden Patentansprüche, auch wenn diese Ausbildungen nicht explizit dargestellt sind.Of course, too any constructive training, as far as technically reasonable, under the scope of protection the present claims, also if these training courses are not explicitly shown.
