Description

Die Erfindung betrifft ein Lastschaltgetriebe mit stufenlos verstellbarem Umschlingungsgetriebe und Leistungsverzweigung.The The invention relates to a powershift transmission with continuously adjustable Belt transmission and power split.

Solche Getriebe sind beispielsweise aus 1 der DE 696 20 719 T2 und der 6 der WO 02/057107 A1 bekannt, wobei diese dreiwellige Planetengetriebe aufweisen.Such gears are made, for example 1 the DE 696 20 719 T2 and the 6 WO 02/057107 A1, these having three-shaft planetary gears.

Aus 5 der EP 01 43 365 A1 ist ebenfalls ein Lastschaltgetriebe mit stufenlos verstellbarem Umschlingungsgetriebe und Leistungsverzweigung bekannt, welches ein vierwelliges Planetengetriebe mit Stufenplaneten aufweist, wobei das stufenlos verstellbare Umschlingungsgetriebe mehrfach durchfahren wird (6).Out 5 the EP 01 43 365 A1 A powershift transmission with a continuously variable belt transmission and power split is also known, which has a four-shaft planetary gear with step planets, the continuously variable belt transmission being passed through several times ( 6 ).

Die grundsätzlichen Kombinationsmöglichkeiten eines stufenlos verstellbaren Getriebes mit einem vierwelligen Planetengetriebe sind aus den 5 bis 9 der DE 195 22 385 A1 bekannt.The basic combination options of a continuously variable transmission with a four-shaft planetary gear are from 5 to 9 the DE 195 22 385 A1 known.

Aus den 10, 12, 13, 16, 18, 19, 22, 24 bis 28 der DE 100 21 912 A1 sind Lastschaltgetriebe mit einem stufenlos verstellbaren Toroidgetriebe sowie einem mehrwelligen Planetengetriebe mit Dreifach-Planeten und drei Sonnenrädern bekannt.From the 10 . 12 . 13 . 16 . 18 . 19 . 22 . 24 to 28 the DE 100 21 912 A1 Powershift transmissions with a continuously variable toroidal transmission and a multi-shaft planetary transmission with triple planet and three sun gears are known.

Der Erfindung liegt die Aufgabe zu Grunde, alternative Konstruktionen von Lastschaltgetrieben mit stufenlos verstellbarem Umschlingungsgetriebe und Leistungsverzweigung bereit zu stellen.The The invention is based on the object of alternative constructions of powershift transmissions with continuously variable belt transmission and To provide power split.

Die Aufgabe wird gelöst durch die Merkmale der Patentansprüche 1 und 2.The Task is solved by the features of claims 1 and 2.

1a stellt ein erstes Ausführungsbeispiel der Erfindung dar, wobei in 1b das Planetengetriebe PL vergrößert dargestellt ist. 1a represents a first embodiment of the invention, wherein in 1b the planetary gear PL is shown enlarged.

2 stellt ein zweites Ausführungsbeispiel der Erfindung dar. 2 represents a second embodiment of the invention.

Das Getriebe nach 1 weist drei Fahrbereiche auf.The transmission after 1 has three driving areas.

Im Fahrbereich 1 (Anfahren) ist die Kupplung KA geschlossen und alle anderen Kupplungen sind geöffnet. Beginnend mit der ersten Endlage des Umschlingungsgetriebes, bei der die Drehzahl der Abtriebswelle A null ist, wird das Umschlingungsgetriebe bis in seine zweite Endlage gesteuert.in the Driving range 1 (starting), clutch KA is closed and all other clutches are open. Starting with the first end position of the belt transmission, at which is the speed of the output shaft A is zero, the belt transmission controlled to its second end position.

Im Fahrbereich 2, der mit der zweiten Endlage des Umschlingungsgetriebes beginnt, ist die Kupplung K1 geschlossen und alle anderen Kupplungen sind geöffnet. Zu Beginn des Fahrbereichs 2 befinden sich die Kupplungen KA und K1 in ihrem gemeinsamen Synchronpunkt und können geschaltet werden. Das Umschlingungsgetriebe wird von der zweiten Endlage in die erste Endlage gesteuert, in der dann die Kupplungen K2 und K1 synchron drehen.in the Driving range 2, with the second end position of the belt transmission starts, clutch K1 is closed and all other clutches are opened. At the beginning of driving area 2 there are clutches KA and K1 in their common synchronization point and can be switched. The Belt transmission is from the second end position to the first Controlled end position, in which then the clutches K2 and K1 synchronously rotate.

Im Fahrbereich 3, der wieder mit der ersten Endlage des Umschlingungsgetriebes beginnt, ist die Kupplung K2 geschlossen und alle anderen Kupplungen sind geöffnet. Erreicht das Umschlingungsgetriebe im Fahrbereich 3 seine zweite Endlage, dann befindet sich das Planetengetriebe PL im Kupplungspunkt.in the Driving area 3, which again with the first end position of the belt transmission starts, clutch K2 is closed and all other clutches are opened. The belt transmission in driving area 3 reaches its second End position, then the planetary gear PL is in the coupling point.

Bei langer Autobahnfahrt ist es sinnvoll, den Planetenträger w2 mit dem ersten Sonnenrad w3 durch Schließen der Kupplung KD zu kuppeln, weil dadurch das Umschlingungsgetriebe leistungslos geschaltet wird.at long highway drive it makes sense to use the planet carrier w2 to couple the first sun gear w3 by closing the clutch KD, because the belt transmission is thereby switched off.
