Definitions

  • the invention relates to a valve train for an internal combustion engine according to the preamble of claim 1
  • a known valve train, EP 0 798 451 B1 for an internal combustion engine comprises a Camshaft with a sliding cam device.
  • the sleeve-like on the camshaft arranged sliding cam device is with spaced lifting curves and adjacent cam tracks provided with different cam shapes.
  • the lift curves work to adjust the sliding cam device with control pins having actuators together.
  • This valve train offers significant Potentials to be a highly effective variable with comparatively simple means To realize valve control for an internal combustion engine, with the aim of the latter in terms of performance and consumption.
  • valve train 2 From an internal combustion engine 1, which is suitable for installation in motor vehicle, is only one valve train 2 with intake valves 3 and 4 and exhaust valves 4 and 5 - four-valve technology - Shown, each disposed above a combustion chamber of a cylinder are, the latter are not shown.
  • the camshaft 6 and the Intake valves 3 and 4 interact in the manner of a variable valve timing.
  • camshaft 6 is provided with a bush-like disk cam device 10, although axially movable - in the direction A-A - is mounted on the camshaft 6, however rotatably connected to the latter, wherein the camshaft 6 and the Sliding cam device 10 with the interposition of a positive Hub connection 11 cooperate, which in the exemplary embodiment a Dahlnutprofil or a serrated profile is - Fig. 3 -.
  • the sliding cam device 10 has three cam tracks 12, 13 and 14 with different Cam shapes NI, Nil and NIII, leading to a cam block 15th summarized next to each other, the cam block 15 is on both sides of Hubkurven 16 and 17 limited.
  • control pins 18, 19, 20 and 21 having actuators 22,23,24 and 25 provided, the example.
  • Electromagnetic or hydraulic genus which is arranged radially to the sliding cam device 10.
  • the control pins 18, 19, 20 or 21 are engaged with the e.g. as U-shaped recesses 26 and 27 - Fig. 2 - formed stroke curves 16th and 17.
  • the lifting curves 16 and 17 of the cam tracks 12, 13 and 14 bearing Slide cam means 10 indicate the engaged control pins 18, 19, 20 and 21 different Hubkurvensetechnischen Hks on.
  • the lift curve sections Hks the Lifting curves 16 and 17 are according to the outer peripheries of the sliding cam device 10 reproducing figures Fig. 4 and 5 formed by an inlet section 28, a first centering section 29, an adjustment section 30 and a second centering section 31, connected to an extension section 32.
  • a range of recesses 26 and 27 for the control pins 18,19,19 and 21 between the beginning of the inlet section 28 and the End of the second centering 31 is designated AfdS - Fig. 5 -.
  • the inlet section 28 tapers in the direction of the first centering section 29 in the manner of a funnel 33.
  • Dem Funnel 33 is preceded by a first adjustment section 34.
  • the second Centering section 31 a locking section 35 and a second adjustment section 36th downstream.
  • a locking device 37 - Fig. 2 - which at a inner peripheral surface 38 of the sliding cam device 10 three radial circumferential Grooves 39, 40 and 41, wherein the camshaft 6 in the region of the grooves 39, 40th and 41 with a cylindrical recess 42 for a detent ball 43 and a Coil spring 44 is provided.
  • one of the cam tracks 12, 13 or 14 the roller cam follower 9 and thus also the inlet valves 3 and 4 actuate.
  • the Internal combustion engine 1 operates the variable valve timing, i. the Actuators 22, 23, 24 or 25 are activated and one of the control pins 18, 19,20 or 21 brought into engagement with the recesses 26 or 27, due to the Adjusting section 30 to an axial movement of the sliding cam device 10 in the direction A-A and thus to a defined circuit of one of the cam tracks 12,13 or 14th leads.
