摘要

#CMT# #/CMT# The device comprises a planetary gear (4) with elements, such as an internal gear (9), a sun gear (10) and a bar (8). A switching element (6) is provided, by which the third element of the planetary gear is coupled to a gearbox input shaft (11) of a gearbox (3) in a primary switching position (A) and is coupled with one of the two elements of the planetary gear in a secondary switching position (B). The planetary gear serves as an overriding drive in the primary switching position of the switching element and the combustion engine (1) is coupled with an electric machine (2). #CMT# : #/CMT# An independent claim is included for a method for operating a device or a powertrain of a hybrid vehicle. #CMT#USE : #/CMT# Device for a powertrain (Claimed) of a hybrid vehicle. #CMT#ADVANTAGE : #/CMT# Zero-load loss in the electric machine and rolling loss in the planetary gears are reduced at constant speed of the hybrid vehicle, and efficient operation of the powertrain is ensured by performing defined functionality of the powertrain of the hybrid vehicle in a reliable manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a powertrain. 1 : Combustion engine 2 : Electric machine 3 : Gearbox 4 : Planetary gear 6 : Switching element 8 : Bar 9 : Internal gear 10 : Sun gear 11 : Gearbox input shaft A : Primary switching position B : Secondary switching position.
