Problems solved by technology

Ball bearings of this type require a large amount of radial installation space in the cylinder head cover or support frame, however, this hinders the advantages of the cylinder head cover, namely light weight and compact construction
Conventional axial mounting by means of sliding bearings, for example a cam by virtue of two joints being engaged on two sliding surfaces in the housing, also often proves to be problematic due to the fact that in cylinder heads for this type of cam There is little available space in the hood

Embodiment Construction

[0029] according to Figure 1 to Figure 5 , the bearing frame 1 of the internal combustion engine 3 according to the invention or the cylinder head cover 2 of the internal combustion engine 3 according to the invention has at least one camshaft body 4 mounted therein (cf. figure 1 and figure 2 ), the camshaft body 4 is mounted in at least two bearing openings 5 ​​arranged along the bearing channel in the tunnel bearing. Here, the bearing opening 5 completely closes off the camshaft body 4 . According to the invention, at least one axial shaft support ring 6 (see, inter alia, figure 2 and image 3 ) is then arranged on the camshaft body 4 , the axial shaft body bearing ring 6 has an annular groove 7 which is open towards the bearing frame 1 or towards the cylinder head cover 2 . At least one associated engagement element 8 is arranged on the support frame 1 or on the cylinder head cover 2 , which engagement element 8 engages to the annular groove 7 and, as a result, forms...

Abstract

A bearing frame (1) or a cylinder head cover (2) for an internal combustion engine (3) may include at least one camshaft (4) mounted in tunnel bearings in at least two bearing openings (5) arranged along a bearing channel and completely enclosing at least one of the camshaft (4) and a radial bearing, and at least one axial shaft bearing ring (6) arranged on the camshaft (4). The axial shaft bearing ring (6) may have a ring groove (7) which is open towards the bearing frame (1) or towards the cylinder head cover (2). At least one engagement element (8) may be arranged on the bearing frame (1) or on the cylinder head cover (2), which engagement element (8) may engage into the ring groove (7) and forms an axial bearing (10) for the camshaft (4).

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 body according to the preamble of claim 1 . Furthermore, the invention relates to an internal combustion engine and a method for mounting a camshaft body of this type. Background technique [0002] Given the complexity of the camshaft bodies required to actuate the inlet and outlet valves in internal combustion engines, it is becoming increasingly difficult to assemble and install modern camshaft bodies in internal combustion engines. [0003] DE 10331089 A1 already discloses a cylinder head cover of the general type for an internal combustion engine having at least one camshaft body protruding through at least one support bracket for the camshaft body along a bearing channel in the cylinder head cover, bearing The bracket has an opening or bore that completely closes the camshaft body. [0004] DE 10 2007 014 544 A1 already...
