1. A brake system comprising:
a vehicle axle having the following components:
hydraulically operating wheel brakes;
at least one pressure supply device, driven by an electric motor drive, for pressure regulation in the wheel brakes;
at least one electronic control and regulating unit that is assigned to the pressure supply device; and
at least one electric traction motor configured for driving and braking a vehicle wheel or the vehicle axle;
a superordinate control and regulating unit, not located on the vehicle axle, and configured for controlling and/or regulating the at least one pressure supply device and the at least one traction motor;
wherein:
a pressure supply device of the at least one pressure device is provided for two wheel brakes of the vehicle axle, with the pressure supply device supplying pressure to both wheel brakes;
and/or
two pressure supply devices comprising the at least one pressure supply device are provided, each for one wheel brake of the vehicle axle, with each of the two pressure supply devices supplying pressure to one wheel brake;
