An electric axle is provided. The electric axle includes, in one example, an electric machine rotationally coupled to a layshaft via a first gear reduction and a differential rotationally coupled to the first gear reduction, a first axle shaft, and a second axle shaft. In the electric axle, the electric machine is positioned laterally between at least two drive wheels that are rotationally coupled to the first axle shaft and the second axle shaft and a rotational axis of the electric machine is axially offset from rotational axes of the at least two drive wheels.

Electric axle with compact electric machine and gear train layout

An electric axle is provided. The electric axle includes, in one example, a first electric machine directly coupled to a first planetary gear set, a second electric machine directly coupled to a second planetary gear set and a housing. The housing includes a first section that encloses the first electric machine and the first planetary gear set, a second section that encloses the second electric machine and the second planetary gear set, and a decreased diameter section that extends between the first section and the second section.

Electric axle with compact electric machine and gearbox arrangement

Systems and methods for a lockable electric axle are provided. The electric axle includes a first electric machine coupled to a first drive wheel via a first gear set. The electric axle further includes a second electric machine coupled to a second drive wheel via a second gear set, and a locking clutch designed to selectively lock the rotation of a first rotor shaft and a second rotor shaft in the first and second electric machines, respectively.

Electric axle with multiple electric machines and locking clutch

An electromagnetic disconnect system has an output housing having an armature with a coil and an output shaft bearing fixed to it. A pressure plate and a sliding dog clutch are slidably attached to an output shaft that is in rotational contact with the output shaft bearing. This system further has an input housing attached to the output housing. The input housing has an input shaft bearing fixed to it. The electromagnetic disconnect system further has a disengagement spring and an axially fixed dog clutch rigidly attached to an end of an input shaft that is axially disposed through an opening in the input housing and in rotational contact with the input shaft bearing.
