  • the invention relates to a mechanically controllable valve train arrangement with a plurality of gas exchange valves arranged in series, which at least two cylinders arranged in series are assigned, wherein at least one gas exchange valve is a transmission arrangement zugordnet, each transmission arrangement is movably mounted in the cylinder head by means of bearing means and wherein each transmission arrangement with each a Ventilhubverstell responded and a camshaft is operatively connected, each VentilhubverstellISSISS having a rotatable eccentric shaft with control peripheral surfaces with at least one eccentric member which is drivable by a drive device bar, such that different valve lift positions are adjustable.
  • a mechanically controllable valve train arrangement is known from DE 10 2004 003 327 AI.
  • this patent application discloses an arrangement having an eccentric shaft having control peripheral surfaces with Exzenterorganen to ensure stroke adjustments of gas exchange valves between zero stroke and maximum stroke.
  • This embodiment offers a high manufacturing and assembly advantage with high variability.
  • a disadvantage of this known embodiment is that the fact that the transmission arrangement, in particular an intermediate lever of the transmission arrangement is supported during its movement on the eccentric shaft and in this way cause a force which acts eccentrically on the eccentric shaft. This creates a non-constant over the circumference of the Exzenterweile mean torque, which of the Drive device must be intercepted.
  • the object of the invention is therefore to provide a valve train arrangement which avoids the above-mentioned disadvantage and offers the possibility to provide a fail-safe function in the event of a defect of the drive device of the eccentric shaft.
  • the eccentric shaft has at least one cam element, which is arranged in the longitudinal direction of the eccentric shaft outside the control peripheral surfaces and which is in operative connection with a spring-loaded plunger member, wherein the at least one cam element arranged in the circumferential direction in the amount of zero stroke settings of the control peripheral surfaces is.
  • the plunger member acts via a roller on the peripheral surface of the eccentric shaft.
  • a particularly advantageous and friction-free embodiment is provided by the fact that the plunger member acts via a roller bearing on the peripheral surface of the eccentric shaft. It should again be clearly noted that this represents only a particularly advantageous embodiment. It is of course, also possible that the plunger member acts on a smooth contour on the peripheral surface of the eccentric shaft. It is also particularly advantageous if the plunger member has a cage in which a spring member, preferably a coil spring, is mounted.
  • the cam element may be formed on a cam attachment piece which is arranged in a positive and / or non-positive fit on one of the two ends of the eccentric shaft.
  • the eccentric in which all possible contours of the eccentric organs are within a circle formed by the outer diameter of an eccentric shaft bearing, wherein the eccentric shaft has corresponding bearing surfaces, the eccentric can be formed as a so-called push-through eccentric, which offers significant manufacturing and assembly advantages.
  • the drive means drives the eccentric shaft via a gear member, wherein the gear member has a through opening for the eccentric shaft and is positively and / or non-positively connected to the bearing surface.
  • the gear member may have an extension on which the cam member is formed.
  • stop surfaces may be provided in the cylinder head, against which the gear member bears on both sides in the axial direction.
  • each transmission arrangement has at least one pivot lever and at least one rocker arm, wherein the pivot lever engages with a working curve on the gas exchange valve and the rocker arm is in operative connection with the Ventilhubverstell issued and the camshaft and a working contour on the pivot lever attacks.
  • FIG. 1 shows a perspective representation of an embodiment of an inventive valve drive arrangement
  • Figure 2 is a cross-sectional view of the cylinder head mounted in the eccentric shaft of Figure 1 at the level of the cam member, and
  • Figure 3 is a schematic representation of the different position potentials of the eccentric shaft due to the acting moments.
  • FIG. 1 shows an embodiment of a valve drive arrangement 10 according to the invention with a plurality of gas exchange valves 12, 14, 16, 18, 20, 22, 24 and 26 arranged in series.
  • the mechanically controllable valve drive arrangement 10 has four transmission arrangements 28, 29; 30, 31; 32, 33 and 34, 35, which in each case two gas exchange valves 12, 14; 16, 18; 20, 22; 24, 26 are assigned.
  • the transmission arrangements 28, 29; 30, 31; 32, 33; and 34, 35 stored in a known manner in the cylinder head by means of bearings.
  • the bearing means 36, 38 are shown in the present figure, only by way of example for the storage of a pivot lever 56 of the transfer assembly 35.
  • each transmission arrangement 28, 29; 30, 31; 32, 33 and 34, 35 in known manner with a camshaft 40 in operative connection.
  • each transmission arrangement 28, 29; 30, 31; 32, 33 and 34, 35 by control peripheral surfaces 42, 43; 44, 45 (not visible here); 46, 47 and 48, 49 with corresponding adjusting a Ventilhubverstell sensible 41 such controlled that a lesser or higher valve lift of the intake valves 12, 14; 16, 18; 20, 22; 24, 26 is adjustable, this being accomplished by eccentric organs, which are provided on an eccentric shaft 50.
  • the eccentric shaft 50 is driven by a drive device 52 in the present case via a gear 53 designed as a gear 53.
  • eccentric shaft 50 It is designed in this embodiment as a push-through eccentric shaft, in which all possible contours of the eccentric organs are within a circle, which is formed by the outer diameter of an eccentric shaft bearing.
  • drive means 52 can be used both a forward and reverse rotary drive.
  • the eccentric shaft 50 can thus be driven in such a way that, depending on the present position, the valve stroke corresponding to the next operating state can be selected quickly and precisely by the use of the corresponding eccentric members (not shown). Even angles of rotation of> 360 ° can be realized.
  • a mechanically actuable valve drive 54 has the transmission arrangement 35 and the gas exchange valve 26.

  • the rocker arm 58 engages with a working contour not shown on the pivot lever 56.
  • the respective rocker arm an off-center attacking Force exert on the eccentric shaft 50, which generates a torque that rotates the eccentric shaft 50 in a stable position in case of failure of the drive means 50, which causes a zero lift of the gas exchange valves and thus causes the failure of the internal combustion engine.

  • the plunger member 64 is spring-loaded in the present embodiment by a coil spring 66 which is mounted in a cage 68.
  • the torque of the rocker arm is opposed by a torque, resulting in a stable equilibrium position of the eccentric shaft 50, in which a valve lift is not equal to zero (see Figure 3).
  • the cam member 62 may also be disposed over the eccentric shaft 50 via a single cam lobe. It may also be advantageous if the contour of the cam member 62 is within the circle formed by the outer diameter of the Exzenterwellenlagerung. This makes it possible to save the mounting step of attaching the cam member 62.
  • FIG. 2 shows a cross-sectional view of the eccentric shaft of FIG. 1 mounted in the cylinder head at the level of the cam element 62.
  • the cam element 62 is formed on an attachment piece 63 of the gear element 53.

  • the plunger member 64 acts on the peripheral surface of the eccentric shaft 50 via a smooth contour or, for example, a roller.
  • a stable equilibrium position of the Exzenterweile 50 is set as a result of the interaction of the cam member 62 and plunger member 64, wherein in each case a stroke of the intake valves is not equal to zero when actuated by the camshaft 40 is provided.
  • the cam member 62 is formed on the extension piece 63. It should be understood that the cam member 62 may also be formed on a single cam lobe. In this way, a position at one of the ends of the eccentric shaft 50 could be selected.
  • the cam member 62 is formed integrally with the eccentric shaft 50 and that the contour of the cam member 62 is within the circle formed by the outer diameter of an eccentric shaft bearing.
