Definitions
- the invention relates to a cylinder head for a valve-controlled Internal combustion engine.
- the bearing bush is provided on both ends with a collar that on the one hand for the axial bearing of the camshaft and on the other hand for fixing the Bearing bush in the storage chair is used.
- the bearing bush has openings on its circumferential surface which face the pressure oil supply to a camshaft adjuster attached to the camshaft.
- the camshaft 12 which is rotatably mounted in a cylinder head housing 10, has two Pairs of different cams 14 and 16, which are guided in openings 17 Cup tappet (not shown) the valve stroke and the opening and closing times of the Determine intake valves.
- the camshaft 12 has a camshaft 12 driving on its end face Sprocket 18 on, which is part of the camshaft 12 using a Bolt 20 attached axial camshaft adjuster 22 is.
- the structure of the Camshaft adjuster 22 is known from the prior art and is in the The following only in connection with the features essential to the invention described.
- the cylinder head housing 10 has a plurality of bearing seats 24, 24 'in which the camshaft 12 is rotatably mounted. In the cylinder head housing 10 are further screw openings 26 for fastening the cylinder head housing 10 on Cylinder head provided.
- the bearing bracket 24 'arranged next to the camshaft adjuster 22 takes one Bearing bush 30, which performs functions described in more detail below.
- the bearing bush 30 has two collars on its end faces 32 and 34, the collar 32 having two radially arranged recesses 36 has, which correspond to the shoulders of the bearing chair 24 'that the Bearing bush 30 non-rotatably in the recess 38 for receiving the camshaft 12 is held.
- the bearing bush 30 has two pairs on its radial bearing surface 40 of openings 42 and 44 on, via the pressure oil to an inner actuator 46 of Camshaft adjuster 22 can be performed.
- the pressure oil is with the help of a Control valve 48 via pressure oil lines 50 and 52, formed in the camshaft 12 radially circumferential grooves 54 and 56 and arranged in the camshaft 12 Bores 58 and 60 fed to the two pressure chambers 62 and 64, with the help of them the inner actuator 46 and thus the position of the sprocket 18 with respect to the position the cam 14, 16 can be adjusted in the desired manner.
- the bearing bush 30 continues to serve the axial bearing of the camshaft 12, because on one side of the Bearing chair 24 'of the camshaft adjuster 22 on the collar 34 of the bearing bush 30 and on the other side of the bearing block 24 'the collar 32 of the bearing bush 30 on one Collar 66 of the camshaft 12 is flush.
- the bearings of the camshaft 12 are formed in two parts, the upper bearing half-shells, not shown, over Corresponding screw connections are connected to the storage chairs 24, 24 '.
- the bore 68 provided in the bearing bush 30 is used for Camshaft bearing lubrication, while those arranged in the cylinder head housing 10 Oil channels 70 are provided for lubricating oil supply for the tappets.
