Definitions
- the invention relates to a preamble of claim 1 Cylinder head with valve control for an internal combustion engine, one Rocker arms at one end on a ball pin arranged in the cylinder head is positively movably mounted and at the other over a straight line Stop bars with an engaging shaft end of a gas exchange valve whose valve stem is positively guided, and the connection of the two Rocker arm ends in the central area essentially parallel side cheeks having.
- Such a rocker arm for a in a cylinder head of an internal combustion engine arranged valve control is for example from DE-A 195 43 657 known.
- a positionally secured in both end areas as described above Rocker arm is required in connection with an assembled control shaft no additional guidance, for example by means of a hairpin spring or curved leaf spring.
- the generic rocker arm with its on both sides of a valve stem the effective stop bars one from DE-B 18 01 252 known complex guidance of the rocker arm in the cylinder head separately arranged guide surfaces, which are formed on the rocker arm Interact sliding surfaces.
- the invention is based, for a generic rocker arm the task for installation in the cylinder head without separate rocker arm devices to demonstrate the simple and safe assembly of the rocker arm enable.
- one projection on a camshaft bearing bracket and the other Projection is arranged on a collar of the cylinder head and for Longitudinal positioning third projection on the inside on a cylinder head boundary is arranged.
- projections are advantageously in one piece with that formed in the casting Cylinder head connected, if necessary, can be used for transverse positioning diametrically opposite projections can be machined.
- the stop bars are closed with relatively no play arranged the side cheeks of the rocker arm and with relatively wide Stop surfaces formed.
- a cylinder head 1, shown only in sections, for one not shown Internal combustion engine is equipped with a valve control 2, which preferably one designed as a roller lever rocker arm 3.
- the rocker arm 3 is at one end on a ball pin 4 arranged in the cylinder head 1, for example of a hydraulic valve clearance compensation element 5 is positively movable stored.
- the rocker arm 3 is a straight between Stop bars 6 shaft end 7 of a gas exchange valve 8 engaging with play at its valve stem 9 guided positively. The connection continues both ends of the rocker arm 3 in the central area substantially parallel side walls 10 on.
- the projections 11, 11 ' are relative small game to the side cheeks 10 of the rocker arm 3 and arranged with relatively wide stop surfaces 18 formed.
- the invention enables simple assembly of the rocker arm 3 without auxiliary tools, whereby a functionally correct assembly of the rocker arm is achieved and further spring or guide elements are omitted.
