Drive shaft

Abstract

A drive shaft includes at least two coaxial hollow shafts spaced apart in the direction of the rotational axis of the drive shaft, and each of the hollow shafts has an inner opening. At least one function unit, which includes at least one function part disposed, with reference to the direction of the rotational axis of the drive shaft, between a first and a second of the hollow shafts and first and second engagement sections extending in the direction of the rotational axis of the drive shaft, of which the first engagement section is disposed in the inner opening of the first hollow shaft and of which the second engagement section is disposed in the inner opening of the second hollow shaft. The engagement sections of the function unit are pressed into the inner openings of the hollow shafts with the formation of a particular press fit and the first and second hollow shafts are rigidly connected with one another via the function unit. The outer surfaces of the engagement sections include material elevations and/or the wall, delimiting the inner opening of the hollow shaft, of the particular hollow shaft in the end section, in which the press fit is formed with the particular engagement section of the function unit, includes material elevations.
