Abstract
A transmission arrangement for an electric vehicle. The transmission arrangement includes a differential configured to connect a first electric machine to a first and second wheel via a respective first and second driveshaft. The transmission further includes a coupled epicyclic gear configured to connect a second electric machine to the first drive shaft via the coupled epicyclic gear. The transmission arrangement includes a coupled epicyclic gear using a single planet gear which meshes with two sun gears of different size, which can be compared to instead using a stepped planet gear including two planet gear portions of different size.
