Die Erfindung betrifft eine Getriebeeinheit zum Achsantrieb eines Fahrzeuges, umfassend zwei Planetengetriebe (2, 3) mit jeweils einem Sonnenrad (21, 31), einem Planetenräder tragenden Planetenträger (23, 33) und einem Hohlrad (22, 32). Bei einer Getriebeeinheit, in welcher zwei unterschiedliche Gänge mit einer vorteilhaften Übersetzungsaufteilung bei einer einfachen Getriebestruktur geschaltet werden können, ist zwischen den beiden Planetengetrieben (2, 3) eine Doppelkupplungseinrichtung (6) mit zwei lastschaltbaren Kupplungen (61, 62) angeordnet.The invention relates to a gear unit for the axle drive of a vehicle, comprising two planetary gears (2, 3) each with a sun gear (21, 31), a planet carrier (23, 33) carrying planet gears and a ring gear (22, 32). In a gear unit in which two different gears can be shifted with an advantageous ratio distribution with a simple gear structure, a double clutch device (6) with two power shift clutches (61, 62) is arranged between the two planetary gears (2, 3).
Description
Die Erfindung betrifft eine Getriebeeinheit zum Achsantrieb eines Fahrzeuges, umfassend zwei Planetengetriebe mit jeweils einem Sonnenrad, einem Planetenräder tragenden Planetenträger und einem Hohlrad.The invention relates to a gear unit for the final drive of a vehicle, comprising two planetary gears each with a sun gear, a planet carrier carrying planet gears and a ring gear.
Aus dem Stand der Technik sind bereits zahlreiche Getriebestrukturen bekannt, doch sind diese üblicherweise recht aufwändig. So offenbart die
Der Erfindung liegt die Aufgabe zugrunde, eine Getriebeeinheit zum Achsantrieb eines Fahrzeuges anzugeben, in welcher zwei unterschiedliche Gänge mit einer vorteilhaften Übersetzungsaufteilung bei einer einfachen Getriebestruktur geschaltet werden können.The invention is based on the object of specifying a transmission unit for the axle drive of a vehicle, in which two different gears can be shifted with an advantageous ratio distribution with a simple transmission structure.
Erfindungsgemäß ist die Aufgabe durch die Eingangs genannte Getriebeeinheit gelöst, indem zwischen den beiden Planetengetriebe eine Doppelkupplungseinrichtung mit zwei lastschaltbaren Kupplungen angeordnet ist. Durch diese Anordnung werden eine große Übersetzung und gleichzeitig eine große Spreizung ermöglicht. Die Verwendung der Doppelkupplungseinrichtung erlaubt eine konstruktiv einfache Herstellung der Getriebeeinheit.According to the invention, the object is achieved by the transmission unit mentioned at the beginning, in that a double clutch device with two power shiftable clutches is arranged between the two planetary gears. This arrangement enables a large translation and, at the same time, a large spread. The use of the double clutch device allows a structurally simple production of the gear unit.
Vorteilhafterweise ist ein Drehmomenteingang mit der Hohlwelle des ersten Planetengetriebes gekoppelt. Durch diese Verbindung kann die Doppelkupplungseinrichtung konstruktiv einfach mit dem Drehmomenteingang verbunden werden.A torque input is advantageously coupled to the hollow shaft of the first planetary gear. This connection allows the double clutch device to be connected to the torque input in a structurally simple manner.
In einer Alternative ist der Drehmomenteingang mit einem Planetenträger des ersten Planetengetriebes gekoppelt.In an alternative, the torque input is coupled to a planet carrier of the first planetary gear.
In einer Ausgestaltung ist zur selektiven Drehmomentübertragung die erste Kupplung der Doppelkupplungseinrichtung zwischen das Hohlrad des ersten Planetengetriebes und das Sonnenrad des zweiten Planetengetriebes geschaltet, während die zweite Kupplung der Doppelkupplungseinrichtung zwischen dem Planetenträger des ersten Planetengetriebes und dem Sonnenrad des zweiten Planetengetriebes angeordnet ist.In one embodiment, the first clutch of the double clutch device is connected between the ring gear of the first planetary gear and the sun gear of the second planetary gear for selective torque transmission, while the second clutch of the double clutch device is arranged between the planet carrier of the first planetary gear and the sun gear of the second planetary gear.
In einer Variante ist das Sonnenrad des ersten Planetengetriebes mit dem Planetenträger des zweiten Planetengetriebes verbunden.In one variant, the sun gear of the first planetary gear is connected to the planet carrier of the second planetary gear.
In einer Ausführungsform ist der Planetenträger des zweiten Planetengetriebes an einem Gehäuse festgelegt.In one embodiment, the planet carrier of the second planetary gear is fixed to a housing.
Es ist von Vorteil, wenn das zweite Hohlrad des zweiten Planetengetriebes mit einem Abtrieb verbunden ist.It is advantageous if the second ring gear of the second planetary gear is connected to an output.
In einer weiteren Ausgestaltung steht der Abtrieb in einem Zahneingriff mit einem zwei Antriebswellen unabhängig voneinander antreibenden Differentialgetriebe.In a further embodiment, the output is in meshing engagement with a differential gear that drives two drive shafts independently of one another.
Ein weiterer Aspekt der Erfindung betrifft einen Antriebsstrang für ein Kraftfahrzeug, umfassend einen Elektromotor, eine Kupplung und eine Getriebeeinheit. Bei einem Antriebsstrang, welcher zwei Gänge mit einer vorteilhaften Übersetzungsaufteilung bei einer einfachen Getriebestruktur schalten kann, ist die Getriebeeinheit nach mindestens einem, in dieser Schutzrechtsanmeldung erläuterten Merkmal ausgebildet.Another aspect of the invention relates to a drive train for a motor vehicle, comprising an electric motor, a clutch and a transmission unit. In the case of a drive train which can shift two gears with an advantageous ratio distribution in a simple transmission structure, the transmission unit is designed according to at least one feature explained in this patent application.
