Definitions

  • the invention relates to a device for relative rotational angle adjustment a camshaft of an internal combustion engine to the drive wheel after the Genus of the main claim.
  • Such a device is known, for example, from EP 0 781 899 A1.
  • EP 0 781 899 A1 describes a means for changing the rotational position of the camshaft a Internal combustion engine, wherein the camshaft rotatably connected to an internal gear , which has radially arranged wings, the associated cells of a cellular wheel in each divided two opposing pressure chambers.
  • These pressure chambers are Hydraulically acted upon by a control valve.
  • the radial extending walls of the cellular wheel are in the region of its radial outside with Wells provided for receiving dirt particles, the be introduced via the pressure medium in the pressure chambers.
  • the in the pressure medium located dirt particles accumulate depending on the direction of rotation of the Camshaft due to the accelerations acting on them and due to their Inertia essentially in one of the two wells. This is it around the respective rear in relation to the direction of rotation.
  • the on the Front of the respective wing or web of the inner part located Although dirt particles can by its relative movement in the front recess the cell wheel are pressed, but because of their inertia, they will not be there remain. Thus, there is the danger in such an adjustment that especially smaller dirt particles in the sealing gap between the wing or web and cellular wheel penetrate and considerable wear and permanently diminishing Perform sealing effect. In addition, an entry of dirt particles in these Sealing lead to a significantly excessive friction.
  • a particularly simple processing of the cell wheel and a relatively large volume for receiving dirt particles results when the wells in the axial Direction extend over the entire length of the pressure chamber.
  • a particularly good sealing effect on the circumferential surface is achieved when the width the recesses and / or the distances of the recesses less than 20% of the width the adjacent footbridge is.
  • a good and fast absorption of dirt particles at the same time high Sealing effect is achieved when the width of the recesses is about 0.5 to 1 mm.
  • the depth (in the radial direction) is preferably in the range between 0.2 and 0.5 mm.
  • the depressions can, for example, a rectangular cross section exhibit.
  • a manufacturing technology particularly favorable design results when the depressions have an approximately semicircular cross section with slightly conical Have opening area to the interior.
  • a cellular wheel with recesses on its peripheral surface can be particularly advantageous and inexpensive way to be produced as a sintered component.
  • the Wells for receiving the dirt particles can then already at Sintering process to be created with.
  • the processing of the peripheral surface after the Sintering process is - as with components without recess - without further effort or without further costs possible.
  • the camshaft of an internal combustion engine is shown at whose free end the inner part 2 of an adjusting device 3 is arranged rotationally fixed.
  • This inner part 2 is arranged radially in this embodiment with four Webs 4a to 4d provided.
  • the inner part is surrounded by a cellular wheel 5, the on not shown manner connected to the crankshaft of the internal combustion engine is and therefore acts as a drive wheel.
  • the bucket 5 is four inwards projecting radial webs 6a to 6d, between which four cells formed are, through the webs of the inner part in each case two pressure chambers 7a to 7d and 8a are subdivided to 8d. These pressure chambers are designed so that the sum of hydraulically effective surfaces in both adjustment directions is the same.
  • the pressure chambers 7a to 7d are in each case via a radial bore 9a to 9d in the inner part with a Ring groove 10 connected to the camshaft 1.
  • the pressure chambers 8a to 8d are in analogous manner via radial holes 11a to 11d in the inner part with a second Ring groove 12 connected in the camshaft.
  • the annular groove 10 is with the Pressure channel 14 and the annular groove 12 connected to the pressure channel 13.
  • These Pressure channels 13 and 14 are known per se via a camshaft bearing 15 connected to a respective control line 16 and 17 respectively.
  • the two control lines 16 and 17 are formed on a control valve 18, for example designed as a 4/3-way valve connected. This control valve 18 is on the one hand with a pressure medium pump 19th and on the other hand connected to an oil tank 20.
  • the webs are 6a to 6d of the cellular wheel 5 each with their end faces sealingly on the inner Peripheral surface 21 of the inner part 2 at.
  • the webs 4a to 4d of the inner part are with their circumferentially curved end faces 23 sealingly on the inner Peripheral surface 24 of the cellular wheel 5 at.
  • In this inner peripheral surface 24 are a Variety of axially extending recesses 25 incorporated. These wells are in this embodiment as longitudinal grooves with a rectangular cross-section executed. Other cross-sectional shapes, such as e.g. Trapezoidal cross-sections, Triangular cross sections or rounded cross sections are readily possible.
  • the Recesses 25 extend in the axial direction over the entire width of Pressure chambers 7a to 7d and 8a to 8d of the width B of the webs 4a to 4d, 6a to 6d. These depressions are distributed over the circumference at regular intervals.
  • the width b and the distance d are selected so that in each pressure chamber about thirty wells are arranged.
  • At a distance d is here the distance between two adjacent side surfaces of the adjacent depressions Are defined. This distance corresponds to the width of the remaining web 26 of the Peripheral surface, each sealingly abuts the end face 23 of the web.
  • the Width D or the arc length of the end face 23 and the width b and the distances d the recesses are coordinated in this embodiment so that each about ten wells 25 are covered by the end face 23.
  • the width b of the recesses is in the embodiment shown here about 0.75 mm. However, it is readily possible, the width b of To vary wells between about 0.5 mm and 1 mm.
  • the depth (in radial Direction of the recesses 25) is in the illustrated embodiment at about 0.35 mm. However, it is also readily possible, the depth in the area between about 0.2 mm and 0.5 mm.
  • the recesses 25 have in here illustrated embodiment has an approximately rectangular cross-section. It is also readily possible, these wells with an approximately semicircular cross-section with slightly conical opening to the interior to train.
