摘要

A drive apparatus (1) for a motor vehicle has a hollow portal axle (2) that accommodates two electrical machines (4). Wheels (12) are mounted rotatably at opposite ends of the portal axle (2) and can be driven by the electrical machine (4) associated with the respective wheel. A step-down gear mechanism (8, 9) is arranged between each electrical machine (4) and the respective wheel (12) and a separate connection from the respective wheel to the step-down gear mechanism, permits the wheel to be mounted in a non-rigid manner. The respective step-down gear mechanism (8, 9) is connected to the respective wheel (12) by a cardan shaft (10).
