Abstract
(DE)
Die Erfindung betrifft einen Hybrid-Antriebsstrang (1) für ein Hybridfahrzeug (2), aufweisend zumindest die folgenden Komponenten: - eine erste und zweite Antriebsmaschine (3, 8), welche jeweils als Elektromotor mit einem Stator (4, 9), mit einem Rotor (5, 10) und mit einer Rotorwelle (6, 11) mit einer Rotationsachse (7, 12) ausgeführt ist; - eine dritte Antriebsmaschine (13), welche als Verbrennungskraftmaschine mit einer dritten Rotationsachse (15) ausgeführt ist; - eine Abtriebswelle (16) mit einer Abtriebsrotationsachse (17); und ein variables Umschlingungsgetriebe (18) mit einem ersten Scheibensatz (19) und einem zweiten Scheibensatz (20), sodass ein Drehmoment zwischen den Antriebsmaschinen (3, 8, 13) und der Abtriebswelle (16) veränderbar übersetzend übertragbar ist, wobei die drei Rotationsachsen (7, 12, 15) parallel zu der Abtriebsrotationsachse (17) angeordnet sind. Der Hybrid-Antriebsstrang (1) ist vor allem dadurch gekennzeichnet, dass der zweite Scheibensatz (20) koaxial zu der Abtriebsrotationsachse (17) angeordnet mit der Abtriebswelle (16) drehmomentübertragend verbunden ist, und der erste Scheibensatz (19) koaxial zu der ersten Rotationsachse (7) und der zweiten Rotationsachse (12) angeordnet mit der ersten Rotorwelle (6) und der zweiten Rotorwelle (11) drehmomentübertragend verbunden ist. Hier ist ein Hybrid-Antriebsstrang in einer in einem Hybridfahrzeug einsetzbaren kompakten und einfach montierbaren Konfiguration vorgeschlagen.
(EN)
The invention relates to a hybrid drive train (1) for a hybrid vehicle (2), comprising at least the following components: a first and a second drive machine (3, 8) which are each configured as an electric motor having a stator (4, 9), a rotor (5, 10) and a rotor shaft (6, 11) with an axis of rotation (7, 12); a third drive machine (13) which is configured as an internal combustion engine with a third axis of rotation (15); an output shaft (16) with an output axis of rotation (17); and a continuously variable transmission (18) having a first pulley set (19) and a second pulley set (20), such that a torque between the drive machines (3, 8, 13) an the output shaft (16) can be continuously transmitted in an adjustable manner, wherein the three axes of rotation (7, 12, 15) are arranged parallel to the output axis of rotation (17). The hybrid drive train (1) is primarily characterised in that the second pulley set (20) is arranged coaxially to the output axis of rotation (17) and is torque-transmittingly connected to the output shaft (26), and the first pulley set (19) is arranged coaxially to the first axis of rotation (7) and to the second axis of rotation (12) and is torque-transmittingly connected to the first rotor shaft (6) and the second rotor shaft (11). A hybrid drive train that can be used in a hybrid vehicle and has a compact and easily assembled configuration is proposed.

L’invention concerne une chaîne cinématique hybride (1) conçue pour un véhicule hybride (2) comprenant au moins les composants suivants : une première et une deuxième machine d’entraînement (3, 8) comportant respectivement un moteur électrique qui comprend un stator (4, 9), un rotor (5, 10) et un arbre de rotor (6, 11) présentant un axe de rotation (7, 12) ; une troisième machine d’entraînement (13) qui, en tant que moteur à combustion interne, présente un troisième axe de rotation (15) ; un arbre de sortie (16) présentant un axe de rotation de sortie (17) ; et une transmission à variation continue (18) comprenant un premier ensemble de poulies (19) et un deuxième ensemble de poulies (20), de sorte qu’un couple puisse être transmis de manière variable entre les machines d’entraînement (3, 8, 13) et l’arbre de sortie (16), les trois axes de rotation (7, 12, 15) étant agencés parallèlement à l’axe de rotation de sortie (17). Cette chaîne cinématique hybride (1) est surtout caractérisée en ce que le deuxième ensemble de poulies (20) est relié à l’arbre de sortie (16) de manière à transmettre le couple, en étant disposé coaxialement à l’axe de rotation de sortie (17), et en ce que le premier ensemble de poulies (19) est relié au premier arbre de rotor (6) et au deuxième arbre de rotor (11) de manière à transmettre le couple, en étant disposé coaxialement au premier axe de rotation (7) et au deuxième axe de rotation (12). La chaîne cinématique hybride selon l’invention présente une configuration compacte pouvant être utilisée et montée aisément dans un véhicule hybride.
