Abstract
Description
Die vorliegende Erfindung betrifft Getriebe in Vorgelegebauweise gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a countershaft transmission according to the preamble of claim 1
In Geländefahrzeugen und SUV's sind häufig Allradverteilergetriebe vorgesehen, welche eine zusätzliche sehr hohe Geländeübersetzung für langsame Geländefahrt (Crawler) aufweisen. Die erforderlichen Bauteile zur Realisierung dieser Geländeübersetzung bzw. des Crawlerganges sind nach dem Stand der Technik für den Fall eines Schaltgetriebes hinter dem Schaltgetriebe und vor dem Längs-Differenzial angeordnet. Durch diese Anordnung entsteht in nachteiliger Weise ein zusätzlicher Bauraumbedarf und eine deutliche Aggregatverlängerung, was sich zudem negativ auf die Dimensionierung und das Gewicht auswirkt.In off-road vehicles and SUVs are often four-wheel-drive transmissions provided, which an additional very high terrain ratio for slow cross-country drive (Crawler). The required components for realization this terrain translation or the crawler gear are according to the prior art for the case a manual transmission behind the transmission and before the longitudinal differential arranged. By this arrangement arises in a disadvantageous manner an additional one Space requirements and a significant extension of the unit, which is also negative on sizing and weight.
Wenn auf konventionelle Weise ein Gang mit sehr hoher Übersetzung in einem Getriebe in Vorgelegebauweise erzeugt werden soll, dann wird dies mittels einer Kombination aus zwei miteinander kämmenden Stirnrädern mit stark unterschiedlicher Zähnezahl dargestellt, was sich als sehr ungünstig erweist, da hierdurch der Durchmesser des antreibenden Rades mit kleiner Zähnezahl zu klein wird.If in a conventional way, a gear with very high gear ratio to be generated in a gear in countershaft design, then this is done by means of a combination of two intermeshing ones spur gears with very different numbers of teeth represented, which proves to be very unfavorable, as a result the diameter of the driving wheel with small number of teeth too small.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Getriebe in Vorgelegebauweise anzugeben, in das zumindest ein Gang für eine zusätzliche hohe Geländeübersetzung integriert ist, wobei der hierfür erforderliche Bauraum sowie das Gewicht möglichst gering gehalten werden soll und die Dimensionierung der Zahnräder optimiert wird.Of the present invention is based on the object, a transmission Specify in countershaft design, in the at least one gear for an additional high terrain translation is integrated, with the help of this required space and the weight are kept as low as possible should and the dimensioning of the gears is optimized.
Die erfindungsgemäße Lösung soll zudem bei Schaltgetrieben in Vorgelegebauweise, konventionellen Handschaltgetrieben, automatisierten Schaltgetrieben und Doppelkupplungsgetrieben implementierbar sein.The solution according to the invention also with manual transmissions in countershaft design, conventional Manual transmissions, automated manual transmissions and dual clutch transmissions be implementable.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is solved by the features of claim 1. Further Embodiments of the invention and advantages are apparent from the dependent claims.
Demnach wird vorgeschlagen, zur Realisierung des zumindest einen Ganges (Crawlerganges) für eine zusätzliche hohe Geländeübersetzung, in das Getriebe eine zusätzliche Zahnradkette zu integrieren. Hierbei wird erfindungsgemäß die hohe Übersetzung auf insgesamt drei Übersetzungen aufgeteilt, wodurch die Durchmesserverhältnisse der Zahnräder optimiert werden können.Therefore is proposed to realize the at least one gear (Crawler gears) for an additional high terrain ratio, in the gearbox an additional Integrate gear chain. Here, according to the invention, the high translation to a total of three translations split, whereby the diameter ratios of the gears optimized can be.
Die Zahnradkette umfasst eine erste Zusatzwelle und eine zweite Zusatzwelle, die jeweils zwei Zahnräder aufweisen, wobei das erste Zahnrad der ersten Zusatzwelle von einer vorhandenen Verzahnung einer Antriebs- oder Vorgelegewelle des Getriebes angetrieben wird, das kleiner als das erste Zahnrad ausgebildete zweite Zahnrad der ersten Zusatzwelle mit dem ersten Zahnrad der zweiten Zusatzwelle in Eingriff steht und wobei das kleiner als das erste Zahnrad ausgebildete zweite Zahnrad der zweiten Zusatzwelle mit einem auf der Abtriebswelle koaxial drehbar angeordneten Losrad in Eingriff steht, welches über eine geeignete Koppelverbindung bzw. ein geeignetes Schaltelement mit der Abtriebswelle drehfest verbindbar ist.The Gear chain comprises a first auxiliary shaft and a second auxiliary shaft, the two gears , wherein the first gear of the first auxiliary shaft of a existing toothing of a drive or countershaft of the transmission is driven, which is smaller than the first gear formed second gear of the first auxiliary shaft with the first gear of second auxiliary shaft is engaged and wherein the smaller than the first gear formed second gear of the second auxiliary shaft with a loose on the output shaft rotatably mounted idler gear is engaged, which over a suitable coupling connection or a suitable switching element is rotatably connected to the output shaft.
Vorzugsweise ist die zweite Zusatzwelle koaxial drehbar auf der Antriebs- oder Vorgelegewelle angeordnet, kann aber auch frei innerhalb des Getriebes angeordnet werden. Als antreibende Verzahnung auf der Antriebs- oder Vorgelegewelle kann vorzugsweise die Ritzelverzahnung des ersten oder des zweiten Vorwärtsganges oder die Ritzelverzahnung des Rückwärtsganges genutzt werden. Die erste Zusatzwelle kann frei im Getriebe angeordnet sein, wobei es besonders vorteilhaft ist, wenn sie auf der gleichen Getriebeseite angeordnet ist, wie das Rückwärtsgangzwischenrad. Im Rahmen einer vorteilhaften Weiterbildung der Erfindung können das Rückwärtsgangzwischenrad und die erste Zusatzwelle auf der gleichen Achse liegen.Preferably is the second auxiliary shaft coaxially rotatable on the drive or Countershaft arranged, but can also be free within the transmission to be ordered. As driving gearing on the drive or countershaft Preferably, the pinion teeth of the first or the second forward gear or the pinion gearing of the reverse gear be used. The first additional shaft can be arranged freely in the gearbox it being particularly advantageous if they are on the same Transmission side is arranged, as the Rückwärtsgangzwischenrad. As part of an advantageous embodiment of the invention, the Rückwärtsgangzwischenrad and the first additional wave are on the same axis.
In vorteilhafter Weise können die ersten Zahnräder der Zusatzwellen sowie die zweiten Zahnräder der Zusatzwellen bezüglich ihrer Verzahnungen gleich gewählt werden, um den Fertigungsaufwand zu minimieren. Des weiteren können die Schrägungswinkel der Räder einer Zusatzwelle gleich gewählt werden, damit die bei Schrägverzahnung auftretenden axialen Zahnkräfte sich auf den Zusatzwellen jeweils aufheben.In can advantageously the first gears the additional waves and the second gears of the additional waves with respect to their Gears selected the same to minimize manufacturing costs. Furthermore, the helix angle the wheels an additional wave is chosen the same be so with the helical gearing occurring axial tooth forces cancel each other on the additional waves.
Durch die erfindungsgemäße Konzeption wird eine kostengünstige und kompakt bauende Lösung zur Realisierung zumindest eines Ganges für eine zusätzliche hohe Geländeübersetzung zur Verfügung gestellt, welche mit vorhandenen Übersetzungselementen des Getriebes kombinierbar ist und bei der die Dimensionierung der Zahnräder optimiert ist.By the concept of the invention is a cost-effective and compact solution for the realization of at least one gear for an additional high gear ratio to disposal provided, which with existing translation elements of the transmission can be combined and in which the dimensioning of the gears is optimized.
