Abstract

Electric drive axle (100), comprising a first and a second drive shaft (10, 20) being axially aligned, an electric drive module (110) and a differential module (150), wherein the electric drive module(110) comprises an electric motor (111) and a planetary gear set (120), wherein both the electric motor and the planetary gear set are coaxially arranged about the drive shafts, wherein output means(130) of the electric drive module is connected to input means (151) of the differential module, wherein the input means is or can be set in drive connection with the right and left drive shaft, suchthat a drive force generated by the electric drive module can be transferred to the first and / or second drive shaft, wherein the electric drive axel comprises a coupler between the output means and the input means, wherein the coupler is arranged to allow for the output means and the input means to slide into engagement in an axial direction. The electric drive module and the differential module is provided with separate housings and that seals are provided at least between the electric drive modules output means and / or the differential modules input means and one of the housings, such that each housing is a separate sealed volume.

Description

technical field [0001] The invention relates to the field of vehicles, and in particular to hybrid or electric vehicles in which at least one axle is electrically driven. The invention also relates to a modular electric drive axle comprising an electric drive module and a differential module, wherein the differential module can be configured depending on the requirements of the vehicle for which the drive axle is intended replace. Background technique [0002] New propulsion technologies for vehicles have been developed during the last decade in which the traditional internal combustion engine is supported or even replaced by an alternative drive source such as an electric motor, giving new possibilities for the arrangement of the drive source and demand. In particular there is a shortage of space in hybrid vehicles provided with two different propulsion arrangements. For example, in a hybrid vehicle with an internal combustion engine and an electric motor, for example an...
