Embodiment Construction

[0020] according to figure 1 , The cylinder head cover 1 of the present invention includes a bearing device 2 for supporting the camshaft 3 . The supporting device 2 comprises at least two, according to figure 1 , which includes a total of five bearing seats 4 and a connecting element 5 connected to each bearing seat 4 . Each bearing seat 4 comprises a first through-opening 6 through which the camshaft 3 extends, which can be formed, for example, as an assembly camshaft. On the camshaft 3 , cams 7 are arranged one behind the other in the usual manner and are connected to the camshaft 3 in a rotationally fixed manner.

[0021] Together with the connecting element 5 and the camshaft 3 , the bearing seat 4 forms a prefabricated assembly which can be mounted together with the cylinder head cover 1 on a cylinder head, not shown.

[0022] This prefabricated device of the invention comprises a support device 2 and a camshaft 3 and is produced in the following manner:

Abstract

The present invention relates to a cylinder head cover (1) comprising a bearing device (2) for bearing a camshaft (3), wherein the bearing device (2) has at least two bearing blocks (4), which bear the camshaft (3), and a connecting element (5), the bearing blocks (4) are axially penetrated in a first through-opening (6) by the camshaft (3) to be borne and are fixed in an aligned position with respect to one another by means of the connecting element (5), and the bearing blocks (4), together with the connecting element (5) and the camshaft (3), form a zn assembly which can be prefabricated and mounted, together with the cylinder head cover (1), on the cylinder head.

Description

technical field [0001] The invention relates to a cylinder head cover comprising bearing means for supporting a camshaft in a cylinder head. The invention also relates to an internal combustion engine equipped with such a cylinder head cover. Background technique [0002] In existing internal combustion engines, essentially two different camshaft arrangements are established in the cylinder head. In a first configuration, the camshaft is located between the cylinder head and a so-called bearing frame on which the cylinder head rests, wherein the cylinder head cover, usually made of plastic, is screwed to the support by a suitable number of screws on the shelf. Thus, the bearing channel is formed by the bearing half shells in the cylinder head and part of the support frame. This bearing channel has to be machined and marked in the installed state, and it has to be disassembled again in order to install the camshaft. Contrary to these attempts, however, there are a number ...
