Abstract
Description
Die
Zahnräder
a1, a2 und a3 verbinden die Verdrängermaschine a mit der Antriebswelle
Die
Schaltkupplungen K vermögen
Verbindungen herzustellen, und zwar K1 zwischen der Antriebswelle
Das hydrostatische Getriebe ermöglicht ein stufenloses Verändern der Übersetzung des Fahrzeuggetriebes in den einzelnen Gängen, die jeweils bei synchronen Drehzahlen wechseln. Da von der durchzusetzenden Leistung nur ein Teil über das hydrostatische Getriebe fließt, stellen sich für das Fahrzeuggetriebe relativ gute Wirkungsgrade ein. In jedem Gang gibt es einen Betriebspunkt, bei dem die hydrostatische Leistung Null ist.The hydrostatic transmission allows a stepless change the translation of the vehicle transmission in the individual gears, each with synchronous Change speeds. Since of the durchzusetzenden performance only one Part about The hydrostatic transmission flows, posing for the vehicle transmission relatively good efficiencies. There is an operating point in every gear, where the hydrostatic power is zero.
Die Erfindung stellt sich die Aufgabe, ein fünfwelliges Planetengetriebe vorzuschlagen, bei dem im Vergleich zum Stand der Technik kleinere Verlustleistungen entstehen. Dies läßt sich dadurch erreichen, daß bei jeder aktiven Koppelwelle die verlustbehafteten Gleitwälzleistungen nur über zwei in Serie liegende Zahneingriffe vom An- zum Abtrieb fließen. Außerdem soll ein solches fünfwelliges Planetengetriebe mit möglichst wenig Bauraum auskommen.The Invention sets itself the task of a five-shaft planetary gear to propose, in comparison to the prior art smaller power losses arise. This can be achieve that at each active coupling shaft the lossy Gleitwälzleistungen only over Two serially meshing teeth flow from the input to the output. In addition, should such a five-wave Planetary gear with as possible little space to get along.

Planetengetriebe nach der Schrift WO 89/09899A1 besteht aus drei
Planetenstufen. Von der Stufe P1 gehören das Hohlrad
Bei aktiver Koppelwelle C, d. h. im 1. Gang fließen verlustbehaftete Gleitwälzleistungen über die Planetenstufen P1, P2 und P3. Es sind dann fünf in Serie folgende Zahneingriffe beteiligt. Bei Betrieb mit der Koppelwelle A, d. h. im 2. und 4. Gang übertragen die Stufen P1 und P2 verlustbehaftete Gleitwälzleistungen. Es sind dann vier in Serie folgende Zahneingriffe betroffen. Lediglich im 3. Gang, d. h. bei aktiver Koppelwelle E ensteht nur in der Stufe P1 ein Gleitwälzleistungsfluß, den zwei in Serie folgende Zahneingriffe leiten.at active coupling wave C, d. H. in 1st gear lossy Gleitwälzleistungen flow over the planetary stages P1, P2 and P3. There are then five involved in series following dental procedures. When operated with the coupling shaft A, d. H. in the 2nd and 4th gear transfer the Steps P1 and P2 lossy Gleitwälzleistungen. It is then four consecutive dental procedures affected. Only in the 3. Gear, d. H. with active coupling shaft E occurs only in the stage P1 a Gleitwälzleistungsfluß, the two Conduct the following dental procedures in series.

Sowohl bei aktiver Koppelwelle C für den 1. Gang als auch bei aktiver Koppelwelle A für den 2. und 4. Gang übertragen die beiden Stufen P1 und P2 verlustbehaftete Gleitwälzleistungen über jeweils vier in Serie folgende Zahneingriffe. Bei leistungsführender Koppelwelle E, d. h. im 3.

At performance Coupling shaft E, d. H. in 3rd gear, only in stage P1 sliding roller power is generated, the above two consecutive dental procedures are flowing.

Bei leistungsführender Koppelwelle C überträgt nur die Stufe P3 und bei aktiver Koppelwelle A nur die Stufe P2 Gleitwälzleistung, die jeweils über zwei in Serie folgende Zahneingriffe fließt. Anders ist dies bei leistungsführender Koppelwelle E. Hier entsteht in der Stufe P1 Gleitwälzleistung, die infolge der Zwischenplanetenräder p2z vier in Serie folgende Zahneingriffe übertragen.In the case of a power-conducting coupling shaft C, only the step P3 transmits, and with active coupling shaft A, only the step P2 of sliding roller power, which flows in each case via two tooth engagements following in series. This is different in the case of a power-conducting coupling shaft E. Here, in the step P1, sliding roller power is produced which, as a result of the intermediate planetary gears p 2z, transmits four following gear meshes in series.

Planetengetriebe nach der Patentschrift
Bei jeder aktiven Koppelwelle fließt Gleitwälzleistung nur über zwei in Serie folgende Zahneingriffe einer Planetenstufe. Untersuchungen zeigen aber, daß dieses fünfwellige Planetengetriebe einen zu großen Bauraum beansprucht und daher im allgemeinen für Fahrzeuggetriebe nicht in Frage kommt. Außerdem lassen sich die Koppelwellen nicht so anordnen, daß sie sich einseitig befinden, wobei die Wellen C und A innen angeordnet sind und die Welle E außen liegt.at each active coupling wave flows Gleitwälzleistung only over two series of teeth following a planetary stage. investigations but show that this five wave Planetary gear too big Space occupied and therefore not in general for vehicle transmission Question comes. Furthermore The coupling shafts can not be arranged so that they themselves are unilaterally, the shafts C and A are arranged inside and the wave E outside lies.
Der Patentanspruch beschreibt die Lösung der oben gestellten Aufgabe.Of the Claim describes the solution of task set above.
Bei dem erfindungsgemäßen fünfwelligen Planetengetriebe fließt die Gleitwälzleistung bei aktiver Koppelwelle C über die Stufe P3, bei aktiver Koppelwelle A über die Stufe P2 und bei aktiver Koppelwelle E über die Stufe P1, und zwar jeweils nur über zwei in Serie folgende Zahneingriffe. Im Vergleich zum Stand der Technik reduzieren sich so die Verlustleistungen und dies nach Untersuchungen bei kleinerer Baugröße. Die eingangs gestellte Aufgabe ist also gelöst.at the five-shaft planetary gear according to the invention flows the Gleitwälzleistung with active coupling shaft C via the stage P3, with active coupling shaft A via the stage P2 and active Coupling shaft E over the stage P1, in each case only two in series following Dental procedures. Compared to the prior art reduce so the power losses and this after investigations at smaller Size. The initially asked task is solved.
