Embodiment Construction

[0027] According to Figure 1 and figure 2 , the internal combustion engine 1 according to the invention has a bearing frame 2 in which at least one camshaft 3 is mounted. According to FIG. 1 , two camshafts 3 are mounted in a carrier frame 2 of an internal combustion engine 1 . In the following description of the figures and throughout the application, the term "carrier 2" is generally also understood to mean the cylinder head cover 4, so that the camshaft 3 can also be mounted in the cylinder head cover 4 in the same way. According to the invention, the camshaft 3 is channel-mounted in the support frame 2 or in the cylinder head cover 4 at at least two bearing openings 5 ​​arranged along the bearing channel, wherein the bearing holes 5 completely enclose the cam Axis 3. For the axial mounting of the camshaft 3 at least one axial bearing disk 6 is arranged on the camshaft 3 . Furthermore, the support frame 3 or the cylinder head cover 4 has a recess 7 (cf. figure 2 ), the ...

Abstract

The invention relates to a support frame (2) or a cylinder head cover (4) of an internal combustion engine (1) comprising at least one camshaft (3) mounted therein. The essence of the invention is that - the camshaft (3) is channel-mounted in at least two bearing openings (5) arranged along the bearing channel, wherein the bearing openings (5) completely surround the camshaft (3) , - at least one axial support disc (6) is arranged on the camshaft (3), - the support frame (2) or the cylinder head cover (4) has at least one recess (7), the recess open towards the camshaft (3), and wherein the axial support disc (6) is guided at least in sections in the circumferential direction, so that the axial support disc (6), at least with its two opposing shafts The end face regions facing the bearing end faces ( 8 , 8 ′) interact with corresponding side wall regions of the corresponding side walls of the recess ( 7 ) and form an axial support for the camshaft ( 3 ).

Description

technical field [0001] The invention relates to a bearing frame or a cylinder head cover of an internal combustion engine having at least one camshaft. The invention also relates to an internal combustion engine and a method for mounting such a camshaft. Background technique [0002] Camshafts are required to drive the intake and exhaust valves in internal combustion engines, where their assembly and installation is becoming increasingly difficult due to the complexity of modern camshafts. [0003] It is known from DE 103 31 089 A1 that a universal cylinder head cover for an internal combustion engine has at least one camshaft which passes through at least one bearing along a bearing channel for the camshaft in said cylinder head cover A bridge protrudes, wherein the bearing bridge has an opening or bore that completely surrounds the camshaft. [0004] From DE 10 2007 014 544 A1 it is known that an internal combustion engine has at least one camshaft which, in order to for...
