Abstract

A transmission arrangement for an at least partially electrically driven vehicle includes a first electric machine defining a first central longitudinal axis and having a first gear stage and a second gear stage. The arrangement further includes a second electric machine defining a second longitudinal axis and having a first gear stage and a second gear stage. Further, the arrangement includes a transmission housing, with the first and second electric machines being arranged in the transmission housing. Additionally, the arrangement includes a differential drivingly connected to the second gear stages of the first and second electric machines. The first and second central longitudinal axes are axially parallel to each other on a circular path, the circular path being perpendicular to an output axis.
