- the term "gergasse” is understood to mean a bearing receptacle / mounting which is designed to be partially or fully closed such that mounting of the camshaft base body or the camshaft is possible only by lateral insertion of the camshaft body. Insertion of the camshaft, transversely to the axis of rotation thereof, into a corresponding bearing receptacle is not possible with such bearing receptacles.
- the camshaft bearing has been expanded in its inner diameter so that the camshaft, including the cams and functional elements arranged thereon, can be mounted in one piece (inserted laterally) in one piece (so-called tunnel bearing)
- increasing the bearing diameter leads to increased friction in the valve train and a concomitant negative effect with regard to the required installation space
- Body of the cam unit characterized in that it is adjusted starting from one of its two free ends at least partially in its outer diameter to the inner diameter of the bearing means that a lateral insertion of the sleeve body is ensured in the closed bearing receptacle.
- the cam unit is at least partially adapted in its outer diameter to the
