Definitions

  • the invention relates to a camshaft arrangement for changing the relative angular position of at least one first cam of a camshaft relative to a second cam of the camshaft, wherein the arrangement comprises an angle adjusting, which has a stator and a rotatable relative thereto arranged rotor, the rotor rotatably with a Shaft is connected, wherein the stator is rotatably connected to a hollow shaft, wherein the shaft and the hollow shaft are arranged concentrically to each other, wherein the at least one first cam is rotatably connected to the shaft and wherein the at least one second cam is non-rotatably connected to the hollow shaft ,
  • the non-positive connection can be produced by a press fit or a shrink fit between the bore and the cylindrical section.
  • a particularly preferred embodiment provides that the cover element has a largely constant thickness in the axial direction of the shaft and hollow shaft, wherein the cover element is widened in its thickness in the region of the bore, to increase the length of the cylindrical contact surface.
  • the cover element preferably has a flat end face, with the extended thickness then extending into the interior of the arrangement.
  • the cohesive connection can be made by welding the cover element and the hollow shaft.
  • the welding may be a laser beam or electron beam welding.
  • the angle adjustment device is preferably designed as a hydraulic adjusting device.
  • Fig. 1 shows the radial section through a camshaft arrangement of a
  • a camshaft assembly 1 comprising a camshaft 2 having cams (not shown) cooperating in a known manner with gas exchange valves to control gas exchange in an internal combustion engine.
  • An arrangement of this kind serves to vary the valve timing of an internal combustion engine. In most cases, hydraulically actuated adjusters are used.
  • a second driving strategy is to change the timing of one set of intake valves relative to another set of single intake camshaft valves. This can be used when two or possibly three intake valves per cylinder are provided and it is desired to change the timing of one of the intake valves relative to the others on a cylinder.
  • the timing of one set of exhaust valves is changed relative to another set of valves with a single exhaust camshaft. This can be used when two or possibly three exhaust valves per cylinder are provided, where it is desired to vary the timing of one exhaust valve relative to the other on a cylinder.
  • the camshaft cams for example, the intake and exhaust valves of the internal combustion engine are arranged.
  • the angle adjustment device 3 By means of the angle adjustment device 3, it is possible to rotate part of the cams relative to another part of the cams.
  • the camshaft 2 consists of two coaxially arranged shaft elements, namely a shaft 6 and a hollow shaft 7, in which the shaft 6 is arranged coaxially.
  • the located on the camshaft 2 cams are rotatably connected either to the shaft 6 or with the hollow shaft 7. Details of this can be found in EP 1 945 918 B1.
  • the rotor 6 is rotatably connected to the shaft 6, for which purpose a central screw 13 is used. By the central screw 13 a fixed radial and axial connection between the rotor 5 and shaft 6 is ensured.
  • the stator 4 has a cover element 8, which is connected by means of screws 14 to the stator 4. With the lid member 8, the hollow shaft 7 is rotatably connected. The rotationally fixed connection between the stator 4 and the hollow shaft 7 takes place via the cover element 8 connected to the stator 4 in such a manner that the cover element 8 has a bore 9 for receiving a cylindrical portion 10 of the hollow shaft 7. It is provided that in the cylindrical contact surface 1 1 between the cover member 8 and the hollow shaft 7 is a non-positive and / or a cohesive connection.
  • the hollow shaft 7 is seated with its cylindrical portion 10 by means of a press fit in the bore 9.
  • This interference fit can be produced by axially pressing the cylindrical section 10 into the bore 9 and / or also by heat shrinking.
  • the interference fit eliminates all axial and radial play between cover element 8 and hollow shaft 7.
  • the cover element 8 is provided in the region of the bore 9 with a widening 15 extending in the axial direction. With this a sufficient contact length is ensured, so that the connection by means of press fit between the cover member 8 and the hollow shaft 7 is sufficiently strong. Accordingly, the substantially homogeneous thickness d of the cover element 8 is increased over its radial extent in the region of the bore 9 as a result of broadening 15 to the value D, preferably at least 1.5 times, more preferably at least 2 times, the value of d is.

  • the pinion 17 is formed here as a separate component. However, it can also be designed integrated into the stator 4.

  • the figures each show the course of the opening path that a cam exerts on a valve over time.
  • the shaft 6 actuates the exhaust valves, and the control of the exhaust valves relative to the crankshaft of the engine may be adjusted.
  • the actuation of the outlet valves can be seen in the left half of the figure in Fig. 2, while in the right half of the figure, the operation of the intake valves can be seen.
  • the dashed curves for the exhaust valves and the displacement in the direction of the double arrow indicate that the adjustment of the angle adjustment device 3 is used for this purpose.
  • Fig. 3 is for the same construction of the engine as in Fig. 2 to see what the course looks like when the shaft 6 actuates the intake valves. Again, the actuation of the exhaust valves can be seen in the left half of the picture and those of the inlet valves in the right half of the picture. Here, the phasing of the intake valves can now be varied relative to the crankshaft, again recognizable by the dashed curves and the double arrow.
  • the optimized control d. H. the opening and closing, the intake valves depending on the speed and the load state of the internal combustion engine.
  • the volumetric efficiency can be improved, resulting in improved engine torque development, as well as higher fuel efficiency and engine runnability.
  • the duration of the opening of the exhaust valves can be changed, so that the opening time of the exhaust valves can be optimized.
  • An early opening of the exhaust valves before bottom dead center (UT) allows a quick warm-up of the internal combustion engine, which reduces cold-start emissions.
  • FIG. 5 An analogous solution to FIG. 4 is sketched in FIG. 5. Again, a DOHC engine is used. Here, the shaft 6 actuates one or more intake valves per cylinder, while the remaining intake valves are actuated by the hollow shaft 7.
  • the solid lines in the right half of FIG. 5 in turn shows the control of one or more inlet valves with fixed control times, while the dashed lines and the double arrow indicate that the rest of the inlet valves can be temporally changed in their control by means of the angle adjustment device 3 ,

  • the closing time of the intake valves can be optimized. This can be used to drive a Late Intake Valve Closing (LIVC) strategy.
  • LIVC Late Intake Valve Closing
