Abstract

A drive device has two electric drive machines for distributing the torque between two wheels of an axle of a motor vehicle and an inverter unit which is electrically connected to the drive machines for converting an electrical DC signal into a drive-machine-specific electrical AC signal. The two drive machines are arranged spaced apart from one another in the axial direction to form an intermediate space, and components of the inverter unit are arranged in a first area, located in the intermediate space and oriented in a first direction transversely with respect to the axial direction, of the drive device, and in a second area, adjoining the intermediate space and oriented parallel to the axial direction, of the drive device, to form a low-inductance, T-shaped inverter architecture.
