Definitions
- Valve drive device for variable stroke adjustment of a gas exchange valve of an internal combustion engine
- the invention relates to a valve train device for variable stroke adjustment of a gas exchange valve of an internal combustion engine, in which the gas exchange valve is in operative connection with the interposition of a transmission element with a roller rotatable about an axis of rotation with a control path comprising an idle stroke curve and a stroke curve in an end region of a stroke - Actuation of the gas exchange valve by a cam of a camshaft-controlled swivel lever, the spring-loaded swivel lever assigned to the cam via a cam track being supported at the other end for variable stroke adjustment via a positionally adjustable and fixable swiveling pivot point along a circular path controlled by an adjusting device.
- Such a valve train device is known from DE 197 08 484 A1, the pivoting lever in its end region remote from the control path having an arc-shaped toothing for engaging a toothing of a control shaft, which serves as an adjusting device for changing the pivoting position assigned to a specific stroke of the gas exchange valve.
- the pivot point of the swivel lever results from the point of contact of the pitch circles.
- valve train device is also known from DE 42 23 172 C1, the pivot lever pivoted from the cam of a camshaft in its free lever end adjacent to the line contact with one of the to achieve a variable stroke - zero stroke to full stroke Stroke-serving cam is guided over a slot on a bolt fixed to the housing.
- the pivoting lever is subject to a rotational and a translational movement component in its oscillation pivot point, the translational movement component corresponding to the function of a pre-cam or a ramp, but otherwise opposing an increase in the dynamics of the valve train.
- the invention is based on the object of kinematically developing a pivoting lever for the generic valve drive device in such a way that it enables increased valve train dynamics in the case of a purely rotary movement or pivoting movement.
- a circular path arranged on a housing part of the internal combustion engine serves as a backdrop with a radius "R" around the axis of rotation of the role of the transmission element of the controlled position-variable support of the pivoting lever, the control path of the pivoting lever in the transition area between Idle stroke curve and stroke curve is formed with a ramp set on a valve clearance in the valve train device.
- the advantage of the invention is that the pivot point of the pivoting lever forms an invariable instantaneous pole during the stroke actuation for a set valve stroke and thus a translational movement component is advantageously avoided.
- the Control time when changing the stroke of the gas exchange valve can be shortened to a much greater extent, with delayed opening and closing sections in partial strokes essentially being eliminated.
- the invention results in a valve train device of high rigidity, which is furthermore advantageous for increased valve acceleration.
- the valve train device according to the invention enables an actual zero stroke and, at full load, a maximum opening gas exchange valve increases torque combined with high speed stability.
- the pivot lever at its end remote from the control path is supported against the housing-side circular path or link via a roller that can be rotated about an axis and can be fixed in each case by means of the adjusting device in such a way that it is controlled along an equidistant line from the circular path displaceable axis of the roller forms the swing pivot point of the pivot lever serving the respective variable stroke adjustment.
- the instantaneous pole or oscillation pivot point is shifted according to the invention into the axis of the circular path roller of the swivel lever a valve train device of reduced wear with much less friction and high functional accuracy, wherein the energy for the adjusting device is also advantageously reduced.
- a roller rocker arm supported on the housing side via a hydraulic valve lash adjuster is provided as the transmission element, the ramp provided for replacing the translational movement component which has been omitted being designed for an essentially constant stroke speed with a maximum stroke exceeding the greatest possible valve lash.
- a valve train device 1 is used for variable stroke adjustment of a gas exchange valve 2 of an internal combustion engine, not shown, the gas exchange valve 2 being one of a plurality of identical intake valves of a cylinder of the internal combustion engine, not shown.
- the gas exchange valve 2 with the interposition of a transmission element 3 with a roller 5 movable about an axis of rotation 4, is operatively connected to a control path 6 comprising an idle stroke curve 6 ′ and a stroke curve 6 ′′, which is in an end region of a for stroke actuation of the gas exchange valve 2 is arranged by a cam 7 'of a camshaft 7-controlled pivot lever 8.
- the pivot lever 8 which is assigned to the cam 7' without play by means of a spring 9 via a roller 10, is on the other hand for variable stroke adjustment of the gas exchange valve 2 by means of a position-changer controlled by an adjusting device 11 and fixable swing fulcrum 12 supported along a circular path.
- the spring-loaded pivot lever 8 is remote from its control path
- a roller 17 which is rotatable about an axis 16, against the circular path 14 or link 15 on the housing side, and can be fixed in each case by means of a cam plate 18 of the adjusting device 11 under the action of the spring 9 such that the along an equidistant line 19 to the circular path 14 or Link 15 controlled displaceable axis 16 of the link-side roller 17 in the respective variable
- Stroke serving swing pivot 12 of the pivot lever 8 forms. It is advantageously achieved with the invention that the pivot point 12 of the pivot lever 8 forms an unchangeable instantaneous pole for a set, reduced stroke or for each stroke during the respective stroke actuation.
- the translational movement components of the oscillating lever 8 mentioned in the introduction to the description are omitted.
- the control path 6 of the swivel lever 8 is designed according to the invention in the transition region between idle stroke curve 6 'and stroke curve 6" with a ramp 20 which is adjusted to a valve clearance in the valve train device 1.
- valve train device 1 which is embodied kinematically according to the invention, an actual zero stroke of the gas exchange valve 2 can be realized, furthermore there is a greater shortening of the control time when the stroke of the gas exchange valve 2 changes, delayed opening and closing courses during partial strokes are eliminated or significantly reduced, so that a larger maximum valve acceleration can advantageously be achieved. Furthermore, there is also an improved and increased torque curve at the full load of the internal combustion engine.
- the link roller or circular roller 17 of the pivot lever 8 is arranged on a pin 21 or on a roller bearing on a pivot 21 connected to the pivot lever 8.
- cam roller 10 of the pivot lever 8 is also needle-bearing, the same applies to the roller 5 of the transmission element 3.
- a roller rocker arm 23 supported on the housing side via a hydraulic valve lash compensation device 22 is provided as the transmission element 3, the roller 5 of which is connected to a control path 6 of the Swing lever 8 cooperates, which has a ramp 20 designed essentially for a constant lifting speed with a maximum stroke exceeding the greatest possible valve clearance.
- a cup tappet with a roller is also conceivable as the transmission element 3, and also a rocker arm with a mechanically adjusted valve clearance.
