Definitions

  • the invention relates to a spring arrangement for a variable valve train of an internal combustion engine with an intermediate lever, at least one camshaft roller on the intermediate lever, which rests against a camshaft, a link roller on the intermediate lever, which abuts against a link, at least one control shaft roller on the intermediate lever, which rests against a control shaft and is arranged on the side facing away from the backdrop of the camshaft pulley, at least one working cam contour which is formed at the opposite end of the intermediate lever to the camshaft and acts on a roller cam follower of a gas exchange valve and at least one spring element, via which the camshaft roller of the intermediate lever against the camshaft and the Sliding roller is loaded against the backdrop.
  • Variable valve trains have become known in recent years for reducing fuel demand and emissions in various designs.
  • the roller drag of the gas exchange valves is no longer actuated directly via the camshaft but via a working cam contour of an intermediate lever.
  • this intermediate lever Upon rotation of the camshaft, this intermediate lever is guided over a first roller on a contour, so that this tilting movement of the intermediate lever has a movement of the working cam contour on the role of Rollenschlepphebels result.
  • how the working curve acts on this roller rocker arm is dependent on the position of a rotatable control shaft which acts on a second roller of the intermediate lever.
  • spring elements are used, which are usually designed as double torsion springs with two oppositely wound helices and their two spring legs each biased against one of the cam follower, while the intermediate leg is clamped, for example, on the component forming the link.
  • a secondary spring biased biased in height of the axis of the control shaft roller against the intermediate lever and so press the roller against the control shaft is in the DE 10 2007 047 582 A1 on the backdrop component and in the DE 10 2004 003 327 A1 attached to the control shaft.
  • an end leg of the spring element biased against the working cam contour and the camshaft side of the intermediate lever abuts against a contact surface of the intermediate lever and the spring element on the contact surface has a force component in the direction of the camshaft and in the direction of the backdrop, wherein the contact surface on the to the working curve contour opposite side of a rotation axis of the camshaft roller is arranged on the intermediate lever, so that the spring element generates a torque about the axis of rotation of the camshaft pulley of the intermediate lever, a secure contact of the intermediate lever is made to the camshaft and the scenery.
  • the bearing clearances and tolerances of the intermediate lever are compensated and distributes the forces acting on the waves particularly advantageous.
  • the intermediate lever Due to the generated torque, the intermediate lever also enters into a fixed abutment with the control shaft, but without these being subjected to an excessive contact pressure. Accordingly, a sufficient contact force is produced by means of a single spring element for all contact points of the intermediate lever.
  • the spring element is a double leg spring, whose intermediate leg is attached to the bearing housing of the variable valve drive and whose end legs bear against each biased a projection forming the projection of two juxtaposed intermediate lever members of the intermediate lever.
  • the helix of the spring element is arranged on the side facing away from the camshaft and the roller rocker arm side of the intermediate lever.
  • the spring element is easy to install and, if necessary, to change due to the good accessibility.
  • the helix of the spring element on the side facing the roller rocker arm is the Camshaft arranged, whereby the required space is reduced.
  • the helix is arranged in the region of an axial extension of a rotation axis of a roller of the roller cam follower.
  • the desired forces and torques can be introduced in a suitable manner and on the other hand, the spring element can be integrated in a compact manner in the variable valve train.
  • the two juxtaposed Rollenschlepphebel which are associated with a double leg spring between the two helices of the double leg spring are arranged so that a good accessibility of the spring element is maintained.
  • the two helices of the double leg spring between the two juxtaposed Rollenschlepphebeln which are associated with a double leg spring arranged, whereby the spring leg lengths can be formed shortened.
  • a spring arrangement for a variable valve train of an internal combustion engine with which the required contact forces are produced by means of only one spring element in all three desired contact points and, in addition, no excessive forces are exerted on bearings or rollers.
  • the intermediate lever is reliably positioned, its bearing clearances compensated and created a tolerance compensation. There is a low installation effort and space requirements.
  • variable valve train shown in the figures consists of a camshaft 10 which is operatively connected via an intermediate lever 12 to a roller cam follower 14, which in turn has a connection to a valve rod 16 of a gas exchange valve 18 serving as an inlet valve.
  • it is an internal combustion engine with two intake valves per cylinder, each associated with a roller cam followers 14.
  • the intermediate lever 12 In order to transmit the actuating force of the camshaft 10 to the gas exchange valve 18, the intermediate lever 12 must be positioned and guided. For a completely defined, guided tilting movement for actuating a gas exchange valve 18, the intermediate lever 12 must have three contact points. In the present exemplary embodiment, there are a total of five contact points, since two gas exchange valves 18 are to be actuated via the one intermediate lever 12, which has two intermediate lever members 20 for this purpose, which have a common axis of rotation 22 are connected to each other, on the inside of the two intermediate lever members 20 each have a camshaft roller 24 is arranged and on the between the two intermediate lever members 20 a link roller 26 which bears against a gate 28 which is fixed to the bearing housing, not shown.
  • the other two contact points consist between a control shaft 30 and two control shaft rollers 32, one of which is arranged in the interior of an intermediate lever member 20 each.
  • the two control shaft rollers 32 are mounted in the intermediate lever members 20 and are located between the camshaft pulley 24 of the respective intermediate lever member 20 and an opposite to the camshaft pulley 24 end of the intermediate lever member 20 working cam contour 34 which abuts against a cam follower roller 36 of the roller cam follower 14.
  • a spring element 44 is used in the form of a double leg spring according to the invention.
  • This has two oppositely wound helices 46, which are connected to each other via an intermediate leg 48 with a U-shaped inversion.
  • the spring element 44 has end legs 50.
  • this spring element 44 is arranged and formed such that its intermediate leg 48 is fastened in a bearing housing fixedly arranged intermediate leg receptacle 52, which is arranged between the two intermediate lever members 20, the link 28 and the roller cam followers 14. From here, the wires of the spring element extend in opposite axial directions to the respective side of the roller rocker arm 14 opposite to the intermediate leg receiver 52. Approximately in extension of the axis 35 of the rocker arm rollers 36, the respective helix 46 of the spring element is formed outside the intermediate lever 12.
  • helices 46 each extend the end leg 50 of the spring element 44 approximately in the extension direction of the intermediate lever members 20 and that to the end of the intermediate lever members 20 beyond the axis 22 of the camshaft rollers 24, where in each case a projection 54 is formed, which a contact surface 56, against which a bent end 58 of the end leg 50 is biased in the direction of the camshaft 10.
  • the projection 54 is to be arranged on the intermediate lever 12 such that a component of the spring force points in the direction of the link 28.
  • this pressing force by the spring element 44 also creates a torque about the axis of rotation 22 of the camshaft pulley 24 and the intermediate lever 12, which causes the control shaft roller 32 is pressed against the control shaft 30.
  • the spring element 44 produces a defined position of the intermediate lever 12 via the three or five support points on the intermediate lever 12.
  • the already loaded by high forces during operation control shaft roller 32 and control shaft 30 is not burdened by excessive forces, as would be the case if the force would be introduced from the opposite side of the intermediate lever 12.
  • FIG. 2 A substantially same-acting embodiment is in the FIG. 2 represented, wherein the same components are provided with the same reference numerals.
  • the only significant difference between the two embodiments is the arrangement of the spring element 44th
  • This spring element 44 has in comparison to the first embodiment, two helices 46, which are directly axially adjacent to each other, so that the axis of the helices 46 as well as the intermediate leg 48 between the link 28, the camshaft 10, the two intermediate lever members 20 and the Rollenschlepphebeln fourteenth is arranged and is located on the opposite to the control shaft 30 side of the intermediate lever 12.
  • the end legs 50 have between the two intermediate lever members 20 past them and biased behind a projection 54, which on the camshaft 10 and substantially also to working cam contour 34 opposite side of the respective intermediate lever member 20.
  • This projection 54 is arranged so that resulting force vector has a component which points in the direction of the camshaft 10 and has a component which points in the direction of the guide 28.
  • a torque is generated about the axis 22, by which a contact force between the control shaft roller 32 and the control shaft 30 is formed.
  • this spring element is somewhat more expensive to assemble, it requires less installation space.
  • a secure system of the intermediate lever is ensured in the required support points with only one spring element. The contact forces are distributed so that no overloading of the rollers or bearings is to be feared. The installation effort and the required installation space are minimized.
  • the two helices can also be arranged above the gate on the opposite side to the camshaft and engage behind the corresponding projection on the one hand to generate the contact force against the camshaft and the link and on the other hand the torque about the camshaft axis, through which the control shaft roller against the control shaft is charged.
  • the spring assembly for differently constructed variable valve trains or engines are suitable, so that, for example, a different number of intake valves per cylinder is needed. Further modified arrangements are conceivable within the scope of the main claim.
