Definitions
- the invention relates to a Device for stroke adjustment of a gas exchange valve in the cylinder head Internal combustion engine, one interacting with the gas exchange valve
- the transmission element is in line contact with an idle stroke curve and one Stroke curve control path on one lever
- the other Lever end in line contact is with a cam on one in the cylinder head controlled rotatable and fixable control shaft
- one in the cylinder head for Control shaft camshaft arranged in parallel via a cam on a cam track acts on the swivel lever to actuate the gas exchange valve.
- Such a device is known for example from DE 42 23 172 C1.
- the to achieve a variable stroke - zero stroke to full stroke - from Cam of a camshaft pivoted swivel lever in its free Lever end adjacent to the line contact with a stroke adjustment Cam is guided over a slot on a bolt fixed to the housing.
- this slot guide many swivel levers on a common guide pin or common guide rod a multi-cylinder internal combustion engine increased friction with the danger a tilt of the swivel lever (s).
- the common Guide rod for the swivel levers of all cylinders of the internal combustion engine an increased space requirement.
- the invention is based, for a device for stroke adjustment the task a gas exchange valve a space-saving construction without the risk of to show frictional tilting of the swivel lever.
- each pivot lever has a common one Hinge pin is guided by means of two spaced-apart articulation levers.
- the device for stroke adjustment can be subjected to higher loads on the swivel lever are without the risk of removing line contact. This affects advantageous on acoustics and wear of the device. Further reduced in advantageously the friction. Through the safer according to the invention Swivel lever can also reduce the preload of the return springs, malfunctions are nevertheless excluded.
- a device 1 for stroke adjustment of a gas exchange valve 2 in the cylinder head 3 ( Figure 3) of an internal combustion engine, not shown, includes one with the gas exchange valve 2 cooperating transmission element 4, which in 5 via a roller Line contact is with an idle stroke curve 6 'and a stroke curve 6' ' Control path 6 on a pivot lever 7.
- the pivot lever 7 is on other lever end 8 at 8 'in line contact with one of the stroke settings of the Gas exchange valve 2 serving cam 9 controlled on one in the cylinder head 3 rotatable and fixable control shaft 10, one in the cylinder head 3 for Control shaft 10 arranged in parallel camshaft 11 via a cam 12 on a Cam track or roller 13 on the pivot lever 7 for actuating the gas exchange valve 2 acts.
- the articulation point 17 of the articulation lever 16 on the swivel lever 7 through an intersection of two circular arcs "K 1 , K 2 " around the end points 18, 18 'is a fictitious trajectory 19 of the axis of rotation 15 of the control shaft 10, approximated by an arc determined, the fictitious trajectory 19 of the control shaft axis of rotation 15 with a fixed four-bar joint a, b, c with the coupling "b" pivot lever 7 serves as a kinematically equivalent replacement of the real adjustment of the cam 9 for the area of the idle stroke curve 6 ', the End points 20, 20 'determine the circular arc centers 18, 18' on the fictitious trajectory 19.
- crank “a” is finally the distance from the center of curvature of the cam track or the axis of rotation 23 of the roller 13 of the pivot lever 7 from the axis of rotation 24 of the camshaft 11 acting on the roller 13 via the cam 12 fixed.
- FIG. 1 A possible embodiment of the articulation lever 16 can be seen in FIG. 1, the upper part of the articulation lever 16 being bow-shaped for easier assembly is executed. It is non-positive on the cylindrical part of the control shaft 10 held, and can also be secured against detachment.
- the pivot lever 7 is preferably via a common hinge pin 25 by means of two spaced-apart, fork-like link levers 16 guided.
