Abstract

A chassis (1) for a motor vehicle has an electrical axle (2) with two electrical machines (4) for respectively driving two wheels (6). The chassis (1) also has a step-down gear mechanism (10, 11) arranged between the respective electrical machine and the associated wheel. Each step-down gear mechanism is connected to the respective wheel by a cardan shaft. The respective rotation axes (5, 5) of the two electrical machines are arranged parallel and next to one another. The chassis enables each wheel to be mounted in a non-rigid manner and permits the overall length of the electrical machines to be varied on account of the arrangement of the rotation axes of the electrical machines.
