Definitions
- the invention relates to a preamble of claim 1
- Cylinder head with valve control for an internal combustion engine with a rocker arm form-fitting at one end on a ball pin arranged in the cylinder head is movably mounted and at the other via a between straight stop bars with play engaging shaft end of a gas exchange valve on the Valve stem is positively secured, and the connection of both rocker arm ends has essentially parallel side cheeks in the central area, being spaced with play in the transverse direction of the rocker arm to its side cheeks Arranged projections are provided on parts of the cylinder head.
- Such a rocker arm for a in a cylinder head of an internal combustion engine arranged valve control is known for example from US-A 4 791 893.
- This known rocker arm is for the simultaneous actuation of two valves two arms, which makes the rocker arm especially at high Engine speeds and / or uneven valve closing movements are encouraged to jump or tilt, which is disadvantageous for the valve train can.
- To secure this position it is designed without a positioning spring device
- the projections arranged with play on both sides serve as rocker arms on the cylinder head.
- 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 serving 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.
- 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 one end, for example, on a ball pin 4 arranged in the cylinder head 1 of a hydraulic valve clearance compensation element 5 is positively movable stored.
- the rocker arm 3 is via a between straight stop bars 6 engaging shaft end 7 of a gas exchange valve 8 at its end Valve stem 9 guided positively secured.
- the connection between the two points further Ends of the rocker arm 3 in the central region substantially parallel side cheeks 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.
