Definitions
- the invention relates according to the preamble of claim 1 to a Arrangement of a camshaft in the cylinder head of an internal combustion engine, in which the arranged in the cylinder head via a plain bearing combined with a thrust bearing Camshaft is equipped with a hydraulically controlled phaser, the a hydraulic medium from arranged in the cylinder head channels over a circumferential with a cylinder head side housing cooperating shaft collar and further channels in the camshaft is supplied, wherein the first channels with the second channels arranged in the shaft collar, covered by the housing and outwardly sealed circumferential grooves are in communication.
- Such an arrangement of a camshaft is known for example from FIGS and 4 of the German patent DE 195 25 836 C1.
- This known arrangement of a separate Wellenbundes next to a separate combined sliding / thrust bearing disadvantageously requires an additional length of the camshaft.
- the invention is based on the object, the generic arrangement of a To improve camshaft so that a camshaft with a shorter overall length achieved.
- camshafts 1, 1 ' which are each shown in half in FIGS. 1 and 2, differ from each other by phaser side differently shaped ends, what in relation to the inventive arrangement of a camshaft 1, 1 'in Cylinder head 2 of an internal combustion engine not shown in detail but without meaning is.
- a camshaft 1, 1 'in Cylinder head 2 of an internal combustion engine not shown in detail but without meaning is.
- the cylinder head 2 via a combined with a thrust bearing 3
- Slide bearing 4 arranged camshaft 1, 1 'with a hydraulically controlled Phasing plate 5 equipped.
- This phaser 5 is a hydraulic medium from arranged in the cylinder head 2 channels 6 and 7 over a circumferentially with a cylinder head side housing 8 cooperating shaft collar 9 and further channels 10 and 11 in the camshaft 1, 1 'supplied, wherein the first Channels 6, 7 with the second channels 10, 11 arranged in the shaft collar 9, Covered from the housing 8 and sealed to the outside circumferential grooves 12, 12 'in Connection stand.
- Camshaft is inventively proposed that divided in one trained housing 8 arranged shaft collar 9 an integrated arranged Slide bearing 4 with thrust bearing 3 comprises trained with both sides of the sliding bearing 4 axial thrust bearing abutment surfaces 13, 13 'in relation to the slide bearing diameter larger recesses 14, 14 'in the housing 8. In these recesses 14, 14 'engages the camshaft 1, 1' with diameter-adapted Weilbund sections 9 ', 9 "with circumferential or radial clearance such that in the shaft collar sections 9 ', 9 "arranged circumferential grooves 12, 12' only to the respective outer end side 15, 15 'of the housing 8 out in the recesses 14, 14' sealed are.
- a particularly effective and reliable sealing of the circumferential grooves 12, 12 'in the shaft collar sections 9', 9 "against the recesses 14, 14 'in the housing 8 is achieved by means arranged in annular grooves 17 hook rings 18, which in FIG 3 are shown in enlarged detail with cooperating at 19 Hook.
