Abstract
(DE)
Die Erfindung betrifft eine Getriebeeinheit (1) für ein hybrides Kraftfahrzeug (2), mit einem Planetengetriebe (3), wobei das Planetengetriebe (3) mit einem ersten Planetenradsatz (4) und einem zweiten Planetenradsatz (5) ausgestattet ist, einer mit einem Bestandteil (6) des Planetengetriebes (3) gekoppelten elektrischen Maschine (7) sowie mehreren, jeweils eine Bremse oder eine Kupplung bildenden und zwischen einer aktivierten Stellung und einer deaktivierten Stellungen verstellbaren Schalteinrichtungen (8, 9, 10, 11), wobei die Schalteinrichtungen (8, 9, 10, 11) zum Schalten verschiedener Getriebeübersetzungen zwischen einem mit einem Verbrennungsmotor (12) koppelbaren Eingang (13) sowie einem Ausgang (14) und/oder zwischen der elektrischen Maschine (7) sowie dem Ausgang (14) wirkend eingesetzt sind, wobei nicht mehr als vier Schalteinrichtungen (8, 9, 10, 11) zum Umsetzen zumindest zweier unterschiedlicher Getriebeübersetzungen in einem Antriebszustand des Verbrennungsmotors (12), zumindest einer Getriebeübersetzung in einem Antriebszustand der elektrischen Maschine (7) sowie zumindest einer Getriebeübersetzung in einem Rekuperationszustand der elektrischen Maschine (7) durch ihre aktivierten sowie deaktivierten Stellungen vorhanden sind. Zudem betrifft die Erfindung ein Kraftfahrzeug (2) mit einem Verbrennungsmotor (12) und dieser Getriebeeinheit (1).
(EN)
The invention relates to a transmission unit (1) for a hybrid motor vehicle (2), comprising a planetary gearing (3), wherein the planetary gearing (3) has a first planetary wheel set (4) and a second planetary wheel set (5), an electric machine, which is coupled with a component part (6) of the planetary gearing (3), and a plurality of switching devices (8, 9, 10, 11), each of which forming a brake or a clutch, and each can be moved between an activated position and a deactivated position. The switching devices (8, 9, 10, 11) are used for switching various transmission ratios acting between an input (13), which can be coupled with an internal combustion engine (12), and an output (14), and/or between the electric machine (7) and the output (14), wherein no more than four switching devices (8, 9, 10, 11) are present for implementing at least two different transmission ratios in a drive state of the internal combustion engine (12), at least one transmission ratio in a drive state of the electric machine (7), and at least one transmission ratio in a recuperation state of the electric machine (7), as a result of their activated and deactivated positions. The invention further relates to a motor vehicle (2) having an internal combustion engine (12) and having said transmission unit (1).

L’invention concerne une unité de transmission (1) destinée à un véhicule hybride (2), comportant un engrenage planétaire (3), l’engrenage planétaire (3) étant muni d’un premier ensemble de pignons satellites (4) et d’un second ensemble de pignons satellites (5), un moteur électrique (7) raccordé à un composant (6) de l’engrenage planétaire (3), et plusieurs dispositifs de changement de vitesse (8, 9, 10, 11) formant chacun un frein ou un embrayage et pouvant être déplacés entre une position activée et une position désactivée, les dispositifs de changement de vitesse (8, 9, 10, 11) étant montés de manière à agir pour la commutation de différents rapports de transmission entre une entrée (13) pouvant être raccordée à un moteur thermique (12) et une sortie (14) et/ou entre le moteur électrique (7) et la sortie (14). L’unité de transmission ne comprend pas plus de quatre dispositifs de changement de vitesse (8, 9, 10, 11) servant à convertir par leurs positions activées et désactivées au moins deux rapports de transmission différents lorsque l’entraînement est effectué par le moteur thermique (12), au moins un rapport de transmission lorsque l’entraînement est effectué par le moteur électrique (7), ainsi qu’au moins un rapport de transmission lorsque le moteur électrique (7) est en récupération. L’invention concerne par ailleurs un véhicule automobile (2) muni d’un moteur thermique (12) et de ladite unité de transmission (1).
