Abstract

The invention relates to a driveshaft and to a method of producing the driveshaft having three components a first attaching element 1 and a second attaching element 13 and a tube element 8 arranged therebetween. The tube element 8 is provided with a first end face 9 and a second end face 12. Both attaching elements 1, 13 comprise cylindrical receiving faces 4, 16 whose diameter is smaller than that of the tube bore 10 of the tube element 8. This permits a radial adjustment of the elements relative to one another with reference to a longitudinal reference axis 25 in order to keep any out-of-balance minimized. In the axial direction, close tolerances can be observed in that a first reference face 6 of the first attaching element 1 is set relative to the first end face 9 of the tube element at a fixed distance 7. The total nominal length 21 is achieved by introducing the second attaching element 13 by means of its cylindrical receiving face 16 more or less deeply into the tube element 8 between the first reference face 6 and a reference face 20 of the second attaching element, utilizing the compensating tolerance 18. The connections are produced by plasma welding.
