Abstract
An adjustable camshaft, which can be utilized in a motor vehicle, may include at least one fixed cam arranged rotationally fixed on at least one outer shaft segment and at least one adjusting cam arranged rotationally fixed to an inner shaft extending concentrically within the outer shaft segment. A method for producing such an adjustable camshaft may involve arranging an outer shaft segment on an inner shaft, generating a surface modification on a surface of the inner shaft to generate at least one arranging section, arranging a fixed cam on at least one section of the outer shaft segment, and arranging the adjusting cam on the arranging section of the inner shaft.

A method for producing an adjustable camshaft of a motor vehicle, wherein the adjustable camshaft comprises a fixed cam disposed rotationally-fixed on an outer shaft segment and an adjusting cam disposed rotationally-fixed to an inner shaft extending concentrically within the outer shaft segment, the method comprising:
- positioning the outer shaft segment on the inner shaft;
- generating a surface modification on a surface of the inner shaft to generate an arranging section;
- positioning the fixed cam on a section of the outer shaft segment;
- and
- positioning the adjusting cam on the arranging section of the inner shaft.
An adjustable camshaft of a motor vehicle, the adjustable camshaft comprising:
- a fixed cam disposed rotationally-fixed on an outer shaft segment;
- and
- an adjusting cam disposed rotationally-fixed to an inner shaft extending concentrically within the outer shaft segment, wherein the adjusting cam is at least force-fit connected to an arranging section of the inner shaft extending along a portion of the inner shaft, wherein the arranging section comprises a surface modification of a surface of the inner shaft.
An adjustable camshaft of a motor vehicle, the adjustable camshaft comprising:
- an inner shaft;
- an adjusting cam disposed on the inner shaft in a rotatably-fixed manner;
- a first outer shaft segment through which the inner shaft extends, wherein an end of the first outer shaft segment is adjacent to the adjusting cam;
- and
- a first fixed cam disposed on the first outer shaft segment in a rotatably-fixed manner, with the first fixed cam being adjacent to the adjusting cam.
