Abstract

See full text

A length adjustment for a drive shaft, wherein the length adjustment has the following: a first rotary element with a first longitudinal toothing and a second rotary element with a second longitudinal toothing. The first longitudinal toothing and the second longitudinal toothing mesh with each other and are axially displaceable to each other. In an end portion of the first rotary element a tooth gap between two longitudinal teeth of the first longitudinal toothing is obstructed. The radial height of a longitudinal tooth of the second longitudinal toothing is reduced relative to the residual longitudinal teeth such that only the longitudinal tooth reduced in radial height can be axially inserted into the obstructed tooth gap. The tooth gap is obstructed by a locking portion of the first rotary element, produced by forming or a material connection a pin resting in a bore of the first rotary element. The locking portion or the pin is arranged in the tooth gap or in axial extension to the tooth gap.
