A shaft, such as a camshaft for use in the internal combustion engine of a motor vehicle, in which the shaft includes a basic shaft body, a plurality of functional bodies, such as cams, mounted in axially spaced positions on the basic shaft body, and at least one balancing element mounted on the basic shaft body, in which the at least one balancing element is produced separately from the basic shaft body and from the functional bodies, and the functional bodies and the at least one balancing element are subsequently mounted on said basic shaft body, for example, by axial press fitting.

Shaft such as a camshaft for internal combustion engines

A camshaft including a carrier element and a cam, in which the carrier element is composed of carrier segments arranged axially one behind the other along a longitudinal axis such that the carrier segments are axially displaceable relative to each other.

Camshaft

A method of fabricating a camshaft including at least one carrier unit and at least one functional element. The carrier unit is produced at least in part from at least one first blank by way of at least one first machining method, and the functional element is produced at least in part from at least one second blank by way of at least one second machining method. The invention further relates to a camshaft produced by the method of the invention.

Method for the fabrication of a camshaft and a corresponding camshaft

A shaft comprising functional elements, such as an assembled camshaft for an internal combustion engine, a method for producing such shafts, and internal combustion engines equipped with such shafts. The functional elements each have a bore and are produced separately from the shaft main body, and the bore is subsequently press fit onto the shaft body to attach the functional element in an axially and rotationally fixed manner. The shaft is also provided with at least one roller bearing that includes at least one undivided roller bearing element which is mounted on the shaft body between two functional elements, for example, by press fitting.
