Transmission and drive train with transmission

Abstract

A transmission (GT) for a motor vehicle having a transmission input shaft (WGE) to which a drive group (AG) can be coupled and a transmission output shaft (WGA) to which an axle drive (AB) can be coupled On the output shaft of the transmission, there are a plurality of coaxially arranged planetary gear sets (PG1, PG2) and a plurality of form-locking shift elements (SE1, SE2), wherein the first planetary gear set (PG1) One element (PH1) is permanently coupled with the first element (PS2) of the second planetary gear set (PG2) via an intermediate shaft (ZW1) capable of switching between the transmission input shaft (WGE) and the transmission output shaft (WGA) , where the electric machine (EM1) is permanently coupled to this intermediate shaft (ZW1), where the second element (ST2) of the second planetary gear set (PG2) is permanently coupled to the transmission output shaft (WGA), where, in In the first shift position (A) of the form-fitting first shifting element (SE1), the transmission input shaft (WGE) is directly coupled to the transmission output shaft (WGA), while in the form-fitting first shifting In the second shift position (B) of element (SE1), the transmission input shaft (WGE) is coupled to the second element (ST1) of the first planetary gear set (PG1), and wherein, in the form-locking second shift In the first shift position (C) of the shifting element (SE2), the third element (PH2) of the second planetary gear set (PG2) is fixedly connected relative to the housing, while in the first shifting position (C) of the second shifting element (SE2) In the second shift position (D), the third element (PH2) of the second planetary gear set (PG2) is coupled to the second element (ST2) or the first element (PS2) of the second planetary gear set (PG2), And thus the second planetary gear set ( PG2 ) is bridged in direct drive.

Description

technical field [0001] The invention relates to a transmission of a motor vehicle. Furthermore, the invention relates to a drive train of a motor vehicle having such a transmission. Background technique [0002] Various transmissions for motor vehicles are known from practice, such as automatic transmissions and semi-automatic transmissions, which generally have a plurality of friction-locking (reibschlüssig) shifting elements configured as clutches or brakes and / or Or a form-locking (formschlüssig) shifting element configured as claws. Transmissions of this type have a relatively complex construction due to the installation of several shifting elements. There is a need for simpler transmissions which can be used in particular in so-called plug-in hybrid vehicles or in so-called plug-in electric vehicles. Contents of the invention [0003] Proceeding from this, the object of the present invention is to provide a novel transmission of a motor vehicle and a drive train wi...
