Embodiment Construction

[0031] according to figure 1 , the camshaft module 1 has at least one camshaft 2 mounted on said camshaft module 1 (cf. image 3 ) in the supporting device 3, where in figure 1 The camshaft module 1 shown in has two such camshafts 2 which run parallel. Here, the bearing device 3 can be a component of the cylinder head cover 4 or of the bearing frame 4 ′. In order to support the respective camshafts 2, the bearing device 3 has bearing channels 5, such as figure 2 shown, among them, in figure 2 Each support channel 5 in the example shown has six support positions 6 and figure 1 In the example shown in , there are five such bearing points 6 . The respective bearing point 6 is formed in a partition wall 7 which extends transversely to the axial direction 8 of the respective camshaft 2 . like figure 1 As shown, the camshafts 2 each have a drive device 9 at their axial ends, which can be coupled to an associated internal combustion engine, in particular a crankshaft of the ...

Abstract

A camshaft module may include a shaft and at least one functional element. The functional element may have a functional element opening through which the shaft passes. The functional element may be fixed to the shaft in a seat portion of the shaft. The camshaft module may include a bearing arrangement in which at least one bearing portion of the shaft is mounted. The shaft may include at least one adjusting portion axially adjacent to the at least one seat portion. The adjusting portion may have a first outer diameter smaller than a second outer diameter of the seat portion. The functional element opening may have an inner diameter smaller than the second outer diameter of the seat portion and larger than the first outer diameter of the adjusting portion such that a press fit fixing is realized between the functional element and the seat portion of the shaft.

Description

technical field [0001] The invention relates to a production method for a camshaft module having a shaft and at least one functional element, as well as such a camshaft module. Background technique [0002] Camshafts are used in a known manner, for example for actuating inlet and outlet valves of an internal combustion engine, and are sufficiently known from the prior art. Here it is desirable to mount the camshaft in the bearing device and also to provide it as a camshaft module in order to achieve a simplified installation of the camshaft on the associated internal combustion engine. The bearing device can be designed, for example, as a cylinder head cover, so that during assembly or installation of the associated internal combustion engine, only the camshaft module needs to be mounted on said internal combustion engine. [0003] Such a camshaft module is known, for example, from DE 10 2009 060 350 A1. Here, the functional elements of the camshaft module, in particular t...
