Abstract
An assembled shaft, especially a camshaft, crankshaft or driveshaft, consisting of a tubular member and individually slid-on driving elements attached in an essentially force-locking way by hydraulically expanding the tube in portions, with an increased torsional strength, is produced in that between each two driving elements there is slid-on a sleeve which has a diameter greater than that of the tubular member and which comprises collar regions guided on the tubular member, with the collar regions extending underneath the driving elements along half the axial length and being clamped-in in an essentially force-locking way between the tubular member and the driving element.
