Definitions

  • the invention relates to a device for the variable actuation of the gas exchange valves of internal combustion engines according to the preamble of claim 1.
  • Such devices serve to make the control of gas exchange valves so that it is possible to operate reciprocating engines without the usual throttle.
  • Such a device is for example from the DE 101 23 186 A1 known.
  • a rotating cam first drives an intermediate member, which performs an oscillating, pure rotary motion and carries a control cam, which is composed of a latching area and a stroke area.
  • the control cam transmits the necessary for actuation of the valve lift curve on the role of a drag lever-like output member, which in turn actuates the valve.
  • the desired, different Ventilhubkurven be generated by the fact that the center of rotation of the intermediate member is displaced on a circular arc-shaped path which is concentric with the role of the driven member in its position with the valve closed.
  • the center of rotation is formed by a roller provided on the intermediate member, the force acting on a circular arc-shaped track in the housing supported, which is also concentric to the role of the output member, thus forming an equidistant to the path of the center of rotation and which is referred to as a backdrop.
  • the roller mounted on the intermediate member is supported on a cam whose angular position determines the position of the center of rotation on its arcuate path.
  • a device for the mechanical control of the stroke adjustment of the intake valve of an internal combustion engine in which a lifting lever with a working curve acts on a roller rocker arm.
  • the lifting lever is guided displaceably with a driven by a bar roller in a backdrop.
  • the roller attached to the lifting lever is moved over the linearly movable bar along the curve defined by the backdrop.
  • DE 101 23 186 A1 discloses a guided over a roller in a backdrop pivot lever which acts via a lift lever mounted on the lifting cam on a valve actuating transmission element.
  • the pivot lever has a fixedly connected to this pin, on which a link roller is rotatably mounted.
  • the guided in the backdrop scenery role is by means of a cam along the slide track shifted to change the valve lift. To rotate the cam a separate adjustment is provided.
  • the object underlying the present invention is to provide a device which is constructed with the saving of a separate adjustment simple and with few components.
  • the bolt on which the intermediate members are mounted simultaneously formed as an adjusting shaft.
  • it is provided with cams and freely rotatable or stored in pendulum supports, in a four-bar linkage or in a slide.
  • the cams are fixed against rotation on the bolt.
  • the cams are supported directly or indirectly in the housing. With direct support can in the housing
  • Sliders are provided for the cams of a material of increased strength.
  • a suitable adjusting means for example an adjusting motor
  • the desired valve lift curve is set.
  • the adjusting means for example an adjusting motor
  • the bolt or the control shaft displaces parallel to itself during the adjusting movement, a connecting element must be arranged between the two, which permits this displacement.
  • This can be a PTO shaft, a Schmidt clutch, an Oldham clutch or even a gear or chain transmission depending on space requirements.
  • With hydraulic actuation also offers a lever mechanism.
  • the device according to the invention can be provided including an adjustment motor or an adjustment device for all intake or exhaust valves of a cylinder head. If the intake and exhaust valves of a cylinder head are actuated by a common camshaft, then the device according to the invention, including an adjusting motor or an adjusting device, can be provided for all intake and exhaust valves of a cylinder head.
  • the device according to the invention, including an adjusting motor or an adjusting device for each valve of an engine can be provided separately, so that any combinations of valve strokes or opening angles of the individual valves of an engine are possible, including the switching off of individual cylinders. In general, however, you will provide a common adjustment of several valves.
  • one or more additional additional gear members are arranged.
  • the device according to the invention Since it is for the acceptance of a variable valve timing, so the device according to the invention is of great importance to keep the adjustment low and because it is higher in the loaded state of the device or their joints and joints than in the power-free state, the largely closed valve is present, an adjustment according to the invention essentially provided during the common rest periods of all valves to be adjusted together. These are derived from the signal of the crankshaft and the camshaft and are getting shorter, the more valves are adjusted together. Their number is therefore limited.
  • the common adjustment of the inlet and outlet valves of only one cylinder give long, easy adjustment rest periods. But it also allows an individual load control of the individual cylinders with an adjustment strategy according to the invention such that the torques of the individual cylinders are controlled for each load condition of the entire engine. This is essential, especially in the lower load range, for smooth engine operation, since the valve lifts normally do not match sufficiently due to tolerances.
  • the signals required for this adjustment strategy are also supplied by the rotary encoder of the crankshaft and assigned to the individual cylinders by the rotary encoder of the camshaft.
  • the inventive solution provides the advantage of creating a safe adjustment for gas exchange valves with simple components. In addition, advantageously a sensitive adjustment is achieved.
  • Fig. 1 shows a camshaft 1, which carries a cam 2. This moves the roller 3 in the end region of the intermediate member 4.
  • the roller 3 is rotatably mounted on the intermediate member 4, which has a one-piece base body attached.
  • the intermediate member 4 has a control cam 5, which is composed of a latching region 5a and a lifting portion 5b.
  • the intermediate member 4 is mounted on a pin 6, the axis 7 is guided on a circular arc-shaped Verstellkurve 8.
  • the center of the circular arc-shaped adjustment curve 8 lies on the axis 9 of the roller 10 of the output member 11, which is supported via a joint 12 in the housing, not shown, and the valve 13 is confirmed. It is clear that an adjustment of the axis 7 on the Verstellkurve 8 in the direction of arrow 14 has a reduction of the opening angle and stroke of the valve 13 result.
  • Fig. 2a, 2b show an embodiment in which the bolt 6 and its axis 7 is guided by a pendulum support 15 positively on the circular arc-shaped Verstellkurve 8.
  • the cylinder-head-side joint 16 of the pendulum support 15 or its axis coincides with the axis 9 of the roller 10 of the output member 11 together.
  • FIG. 2a, 2b An adjusting device not according to the invention for realizing the parallel displacement of the bolt 6 on the Verstellkurve 8.
  • the adjusting 17 carries cams 18 which determine the position of the bolt 6 and its axis 7 on the Verstellkurve 8 via plunger 18a.
  • An adjustment of the axis 7 on the Verstellkurve 8, as shown by the directional arrow 14, is caused by a rotation of the cam 18 and the adjusting shaft 17 corresponding to the direction arrow 14a.
  • the described Adjustment movement has a reduction of stroke and opening angle of the valve 13 result. If the constructive
  • Framework conditions (such as space) allow it, can also be dispensed with the plunger 18 a and the cams 18 can act directly on the bolt 6.
  • Fig. 3 shows a perspective view of the device according to the invention with pendulum support 15 for intake valve 19 and exhaust valve 20 of a cylinder, picked out from a number of cylinders or valves.
  • pendulum support 15 for intake valve 19 and exhaust valve 20 of a cylinder, picked out from a number of cylinders or valves.
  • the cylinder head side hinge 16 of the pendulum support 15 whose axis coincides with the axis 9 of the rollers 10 of the output members 11, so that the pin 6 is forcibly guided on a circular arc-shaped adjustment curve.
  • the bolt 6 according to the invention simultaneously the function of the adjusting. He wears the cams 18, which are supported on mounted in the housing, hardened sliders 21 and is rotatable in the pendulum support.
  • a connecting element of the bolt 6 is connected to the housing-fixed adjusting motor 23.
  • a propeller shaft 22 serves as a connecting element.
  • This embodiment offers considerable advantages in terms of variety of parts, but also space in the area of the actual valve control.
  • other connecting elements such as Schmitt couplings, Oldham couplings, toothed and chain drive, come into question, a certain flexibility for the accommodation of the adjusting motor 23 is given.
  • Fig. 4 schematically shows the interaction of accelerator pedal 40, adjusting motors 23, rotation angle sensor 42 on the flywheel and rotation angle sensor 43 on the camshaft with the engine management 44.
