Abstract
A rotor tube for an electric machine of a vehicle includes an outer tube and first and second coupling sections coupled to the outer tube at opposite end regions of the outer tube relative to a longitudinal axis of the rotor tube. First and second hubs are coupled to the outer tube at the opposite end regions of the outer tube relative to the longitudinal axis of the rotor tube. A ventilation element is coupled to the outer tube. An inner tube is disposed within the outer tube relative to the longitudinal axis of the rotor tube such that the outer tube surrounds the inner tube. At least two components selected from the first coupling section, second coupling section, first hub, second hub, outer tube, ventilation element and inner tube are formed in one piece as a cast component.
