Abstract
The invention relates to a driveshaft and to a method of producing the driveshaft having three components a first attaching element and a second attaching element and a tube element arranged therebetween. The tube element is provided with a first end face and a second end face . Both attaching elements comprise cylindrical receiving faces whose diameter is smaller than that of the tube bore of the tube element . This permits a radial adjustment of the elements relative to one another with reference to a longitudinal reference axis in order to keep any out-of-balance minimized. In the axial direction, close tolerances can be observed in that a first reference face of the first attaching element is set relative to the first end face of the tube element at a fixed distance . The total nominal length is achieved by introducing the second attaching element by means of its cylindrical receiving face more or less deeply into the tube element between the first reference face and a reference face of the second attaching element, utilizing the compensating tolerance . The connections are produced by plasma welding.
