Abstract

An electromechanical drive arrangement for a motor vehicle includes an electromechanical main drive motor, a reduction gear unit comprising a gear input, a gear output, at least one reduction stage and a gear housing that houses the reduction stage, an axle differential gear for branching the drive power guided over the reduction stage into a first wheel drive train section and a second wheel drive train section, and an auxiliary unit that can be driven by the main drive motor via the reduction stage. At least parts of the auxiliary unit are integrated into the gear housing. A switching body is provided in the gear housing such that the drive connection from the reduction stage to the axle differential gear can be switchably closed and switchably separated.

Dependent claims

An electromechanical drive arrangement for a motor vehicle, the electromechanical drive arrangement comprising:

an electromechanical main drive motor comprising a rotor and a stator,
a reduction transmission device which comprises a transmission input, a transmission output, at least one reduction stage and a transmission housing which accommodates the reduction stage,
an axial differential transmission for splitting the drive power between a first and a second wheel drive train section, and
an auxiliary assembly which is driven by the main drive motor via the reduction stage, wherein
the auxiliary assembly is at least partially incorporated into the transmission housing,
a switching element is provided in the transmission housing,
the switching element is designed and incorporated into the drive arrangement in such a way that the drive connection from the reduction stage to the axial differential transmission can be closed in a switchable manner and can be disconnected in a switchable manner by means of said switching element.
