AI Technical Summary

Technical Problem

The existing camshaft support structure on the cylinder head of an internal combustion engine is complicated to install, resulting in weakened cylinder head cover strength and increased weight.

Method used

The camshaft is fixed by radially staggered recesses on its outer periphery, replacing the traditional double flat surfaces. This reduces the size of the auxiliary installation opening and optimizes the design of the cylinder head cover by mirror-symmetrically staggered recesses.

Benefits of technology

It enables simple camshaft installation, reduces the material used and weight of the cylinder head cover, lowers costs, and improves structural stability and installation efficiency.

Abstract

The present invention relates to a camshaft (12, 14) for an internal combustion engine having a recess (20) formed in the circumferential surface (18) on the outer periphery of the camshaft (12, 14) and which is itself open to the outside in the radial direction of the camshaft (12, 14). A tool can be inserted into the recess and thereby placed in a form-locking interaction with the camshaft (12, 14), thereby the camshaft (12, 14) can be fixed in a rotation-resistant manner by means of the tool. The recess (20) is arranged radially offset from the center (M) of the camshaft (12, 14).
