Definitions
- the invention relates to a cylinder head assembly for an internal combustion engine having a cylinder head with at least one operated via a tappet by a camshaft gas exchange valve per cylinder, wherein the tappet is slidably mounted in a bucket tappet housing and wherein the cylinder head is covered by a cylinder head cover. Furthermore, the invention relates to an internal combustion engine with at least one in at least one bore of a Ge housing, preferably a crankcase, rotatably mounted camshaft, wherein the bore is closed by a cover on the side facing away from the camshaft.
- DE 44 21 057 C1 discloses a cylinder head arrangement of an internal combustion engine with a basic housing and a tappet housing inserted therein, as well as an attached cylinder head cover.
- the bucket tappet housing is integrally formed for a plurality of cylinders.
- the leadership and Lü ⁇ tion of the camshaft takes place in divisible bearing blocks, the upper parts are integrated in the cylinder head cover Zy ⁇ and the lower parts are madebil ⁇ det in the main body.
- the multi-part design of the bearing blocks increases the manufacturing and assembly costs.
- a further object of the invention is to fix the camshaft in a defined position in the simplest possible way while carrying out maintenance work. According to the invention, this is achieved in that the camshaft is rotatably mounted in the cylinder head cover, wherein preferably at least one cam shaft bearing is designed as a tunnel bearing. The camshaft is thus inserted axially into the tunnel bearings formed by the cylinder head cover.
- the tappet housing may be integrally formed for a plurality of cylinders, whereby the structural rigidity of the cylinder head is increased. With regard to the simplest possible and cost-effective production, however, it may be advantageous if at least one tappet housing per cylinder is detachably connected to the cylinder head.
- the cylinder head cover can be designed to receive, for example, two camshafts.
- the main oil channel per bucket tappet housing has at least one distribution bore, which is releasably connected with at least one leading to a tappet guide oil supply when placed on the cylinder head Zy ⁇ linderkopfdeckel.
- the tappets can be designed as hydraulic tappets, for example for carrying out an automatic clearance compensation.
- the cylinder head and the bucket tappet housing consist of different materials, where preferably the bucket tappet housing consists of light metal.
- the cylinder head may be made of gray cast iron, cast iron or the like.
- the bucket tappet housing may be formed of a lighter material than the cylinder head, for example of an aluminum material.
- the cover has at least one maintenance fixing device for the camshaft, wherein it is preferably provided that the maintenance fixing device is formed by at least one projection, preferably a pin, of the cover Maintenance condition of the internal combustion engine in a korres ⁇ ponding recess, preferably an axial bore, the camshaft is inserted.
- the maintenance fixing device is formed by at least one projection, preferably a pin, of the cover Maintenance condition of the internal combustion engine in a korres ⁇ ponding recess, preferably an axial bore, the camshaft is inserted.
- recess and projection must be arranged eccentrically to the camshaft axis.
- the maintenance fixing device is arranged on a first end side of the cover facing away from the camshaft in the engine operating state, wherein preferably the cover can be fastened to the housing in the maintenance state about an axis normal to the camshaft axis by 180 °, so that the first end side can be fastened facing the camshaft.
- the maintenance fixing device is connected captively, preferably integrally with the cover. Loss or misplacement of the maintenance fixing device can thus be ruled out. Other additional special tools for preventing rotation during assembly work can be dispensed with.
- FIG. 1 shows a section through a cylinder head arrangement according to the invention
- FIG. 3 shows a cylinder head cover in an oblique view
- FIG. 6 shows the crankcase with cover in a section along the line VI-VI in Fig. 5.
- Figure 7 shows the crankcase in a plan view with the lid in a mounting position. and 8, the crankcase and the cover in a section according to the Li ⁇ never VIII-VIII in Fig. 7.
- the cylinder head assembly 2 has a cylinder head 4 connectable to a cylinder block (not shown).
- the cylinder head 4 is closed by a cylinder head cover 8 upwards.
- Four gas exchange valves 10, 12 are arranged per cylinder in the cylinder head 4, two of which are designed as inlet valves and two as outlet valves.
- Each group of Gaswech ⁇ selventilen 10, 12 is actuated by a respective camshaft 14, 16 via tappets 18, 20.
- the tappets 18, 20 are mounted per cylinder in a cup tappet housing 22, which is bolted to the cylinder head 4.
- camshafts 14, 16 are rotatably supported in camshaft carriers 24, 26 in the form of tunnel bearings, wherein the camshaft bearings 24, 26 are formed by the cylinder head cover 8.
- the camshafts 14, 16 are axially displaced.
- a main oil passage 28, 30 integrated in the cylinder head cover 8 in the cylinder head cover 8 is further per camshaft 14, 16, a main oil passage 28, 30 integrated.
- the main oil passages 28, 30 have distribution bores 32, 34 in their areas facing the tappet housing 22, which communicate with the cylinder tappet cover 8 with oil supply passages 36, 38 of the tappet housing 22 when the cylinder head cover 8 is mounted.
- the oil supply channels 36, 38 lead to cup tappet guides 40, 42.
- the tappets 18, 20 can be designed as hydraulic tappets.
- a bucket tappet housing 22 is provided per cylinder.
- a common tappet housing for all cylinders.
- the crankcase 101 has at least one bore 102 for a camshaft bearing 104 designed as a tunnel cam 104 for a camshaft 103.
- the bore 102 is closed on the outer side facing away from the camshaft 103 with a cover 105, which is fastened to the crankcase 101 via fastening screws 106.
- the cover 105 is formed essentially flat and has a first and a second end face 107, 108 arranged substantially parallel to one another.
- a projection 110 forming a maintenance fixing device 109 is arranged on the first end face 107.
- the pin 110 is advantageously formed integrally with the lid 105.
- the camshaft 103 has an axial bore 111 whose diameter D is dimensioned so that the pin 110 can be inserted into the bore 111.
- the journal 110 and the axial bore 111 must be formed eccentrically with respect to the cam shaft axis 112 and must be equally spaced therefrom.
- the mounting holes 113 of the lid 105 are arranged symmetrically with respect to an axis 114 normal to the camshaft axis 112.
- the maintenance fixing device 109 is designed to be captive with the cover 105, no additional special tools are required, which can optionally be laid. Thus, the cost and Zeit ⁇ effort of maintenance can be reduced.
