Abstract
(DE)
Die Erfindung betrifft eine Antriebsstrangeinheit (10) mit einem zur Übertragung eines Drehmoments zwischen einem Antrieb (16) und einem Abtrieb (18) eingerichteten Getriebe (20), mit einer Parksperrvorrichtung (28), aufweisend ein Sperrelement, das zur Einschränkung einer Drehbeweglichkeit eines um eine Drehachse drehbaren Drehbauteils (30) zwischen einer Freigabestellung und einer Sperrsteilung bewegbar ist, weiterhin mit einem Elektromotor (32), der einen Motorabtrieb (34) aufweist und weiterhin mit einer zur Abkopplung des Motorabtriebs (34) von dem Getriebe (20) eingerichteten und betätigbaren Kopplungsvorrichtung (44), wobei die Kopplungsvorrichtung (44) wirksam zwischen dem Elektromotor (32) und dem Getriebe (20) sowie zwischen dem Elektromotor (32) und der Parksperrvorrichtung (28) angeordnet ist und einem Verfahren zum Betätigen der Parksperrvorrichtung (28) sowie eine elektrische Achse (38) in einem Fahrzeug (14) mit einer derartigen Antriebsstrangeinheit (10).
(EN)
The invention relates to a drivetrain unit (10) with: a transmission (20) designed for the transfer of a torque between a drive unit (16) and an output (18); a parking lock device (28), comprising a locking element which can be moved to restrict the rotational mobility of a rotating component (30) which can rotate around an axis of rotation between an enabled position and a blocked position; furthermore an electric motor (32), which has a motor power take-off (34); and furthermore a clutch device (44), which is designed and can be actuated to disengage the motor power take-off (34) from the transmission (20), wherein the clutch device (44) is arranged effectively between the electric motor (32) and the transmission (20) and between the electric motor (32) and the parking lock device (28). The invention also relates to a method for actuating the parking lock device (28) and to an electric axle (38) in a vehicle (14) with a drivetrain unit of this kind (10).
(FR)
L’invention concerne une unité de chaîne cinématique (10) comprenant un engrenage (20) conçu pour la transmission d’un couple entre un entraînement (16) et une prise de force (18), comprenant un dispositif de verrouillage de stationnement (28) présentant un élément de verrouillage, qui peut être déplacé entre une position de libération et une position de verrouillage pour la restriction d’une capacité de mouvement en rotation d’un composant rotatif (30) pouvant tourner autour d’un axe de rotation, comprenant en outre un moteur électrique (32), lequel présente une prise de force de moteur (34) et comprenant en outre un dispositif de couplage (44) conçu et pouvant être actionné pour le découplage de la prise de force de moteur (34) de l’engrenage (20), le dispositif de couplage (44) étant disposé de manière opérationnelle entre le moteur électrique (32) et l’engrenage (20) ainsi qu’entre le moteur électrique (32) et le dispositif de verrouillage de stationnement (28) et un procédé pour l’actionnement du dispositif de verrouillage de stationnement (28) ainsi qu’un axe électrique (38) dans un véhicule (14) comprenant une telle unité de chaîne cinématique (10).
