Embodiment Construction

[0019]According to the FIGS. 1-3, a camshaft 1 of an internal combustion engine 2 according to the invention comprises at least one function device 3 that is connected to the camshaft 1 via a shaft-hub connection, in particular via a press fit connection, which is put together of at least two different function elements 4. The individual function elements 4 in this case fulfil different functions and are merely combined in the common function device 3 to simplify the assembly. At least one function element 4 in this case can for example be formed as a gear wheel 5, in particular as a coupling gear wheel, as a cam, as a pump actuating device, as an encoder wheel 6, as a belt pulley, as a coupling 7, in particular as an Oldham coupling, or as a chain wheel 5′. The function device 3 represented according to FIG. 1 thus has three function elements 4, namely the coupling 7, the chain wheel 5′ or gear wheel 5 as well as the encoder wheel 6. By combining a plurality of function elements 4 ...

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to German Patent Application DE 10 2012 223 811.5 filed Dec. 19, 2012, which is hereby incorporated by reference in its entirety.TECHNICAL FIELD[0002]The present invention relates to a camshaft of an internal combustion engine having at least one function device connected therewith via a shaft-hub connection according to the preamble of claim 1. The invention additionally relates to a function device for such a camshaft and to an internal combustion engine having at least one such camshaft.BACKGROUND[0003]Generic camshafts are thoroughly known, just as connecting function elements to such camshafts, for example via a thermal joining fit. However, function devices such as for example gear wheels, drive wheels, cams, pump actuating devices, such as for example pump cams for a high-pressure pump or an Oldham coupling for the rotary connection of vacuum or oil pumps are connected to the camshaft by way of pres...
