Definitions

  • the invention relates to a camshaft adjustment device for internal combustion engines of motor vehicles according to the preamble of the claim 1.
  • Camshaft adjustment devices are used in internal combustion engines of motor vehicles the opening time of the intake valves depending on the power requirement of the internal combustion engine Taxes.
  • an intake camshaft adjuster 1 (FIG. 2) and / or an exhaust camshaft adjuster 2 is provided which an endlessly revolving chain 5 with a crankshaft 3 drive connected are.
  • the camshaft adjusters 1, 2 each have one Stator, in which a rotor is housed relatively rotatable, which on the respective camshaft 12, 29 is seated in a rotationally fixed manner. The rotors are with Pressure medium is applied when they are rotated relative to the stator should.
  • the stators of the two camshaft adjusters 1, 2 are each provided with a drive wheel 6, 6 ', via which the chain 5 is led. It is difficult and in confined spaces partly also not possible to mount the chain 5.
  • the invention is based, the generic cam adjusting device the task to be trained so that they can be used even in tight spaces Installation conditions can be easily installed.
  • camshaft adjusting device In the camshaft adjusting device according to the invention two camshaft adjusters in turn via the gear transmission connected to each other.
  • the drive wheel of a camshaft adjuster can be conveniently installed depending on the position, whereby the endlessly rotating drive element even in confined spaces can be easily assembled.
  • the two camshaft adjusters each have a stator, the surrounds a rotor that is rotatable relative to the stator and on the respective Camshaft is fixed against rotation.
  • the rotors of the camshaft adjusters can by printing medium in the desired direction can be adjusted relative to the stator in order to determine the opening time to change the intake valves of the internal combustion engine.
  • the camshaft adjusters are directly engaged with each other via their gears.
  • this Trap is the crankshaft with only one camshaft adjuster connected via the endless drive.
  • the gears of the two engage Camshaft adjuster in a common gear that is non-rotatable sits on an intermediate shaft. For its part, it is via the endless drive drive connected to the crankshaft.
  • the Intermediate shaft rotatably driven by the endless drive, whereby the camshaft adjusters are driven by the gear mechanism become.
  • the camshaft adjusting device has the intake camshaft adjuster 1 and the exhaust camshaft adjuster 2.
  • the sprocket 6 can be single track or be two-lane.
  • that is Sprocket 6 in the exemplary embodiment is formed and has two lanes accordingly two sprockets 7 and 8.
  • the sprocket 6 is connected via a spacer 9 to a ring gear 10, which is advantageous is integrally connected to the stator 11.
  • the stator 11 has a cylindrical jacket 13, which axially projects beyond the ring gear 10 and the at least one in Axial direction extending recess 14, which in the embodiment has a circular cross-section.
  • this deepening 14 positively engages a corresponding projection 15 which the inside of the sprocket 6 is provided.
  • the part of the camshaft adjuster 2 is.
  • the spacer 9 and the sprocket 2 postponed. Then the spacer 9 and the sprocket 6 with screws 16 with the stator 11 and the ring gear 10 connected.
  • the ring gear 10 has a larger inner diameter than the jacket 13 of the stator 11. From the inside of the ring gear 10 protrude the circumference evenly distributed webs 17 from the ring gear 10th connect to the stator jacket 13. The webs 17 have threaded holes 18 into which the screws 16 are screwed.
  • the spacer 9 has thickenings provided distributed over the circumference 19 on which protrude over both sides of the spacer 9 and each have an opening 20 for the passage of the screws 16.
  • the sprocket 6 has an inner circumferential flange 21 which is approximately is provided in half the width of the chain wheel 6 and over the circumference Distributed openings 22 for the passage of the Has screws 16. Since the flange 21 opposite the end faces of the chain wheel 6 is reset, the heads 23 of the screws 16 recessed in the sprocket 6 (Fig. 4). The spacer 9 holds that Sprocket 6 at an axial distance from the ring gear 10.
  • a cover plate 24 (FIG. 4) is fastened with screws 25.
  • the Cover plate 24 secures in a known manner the rotationally on the Camshaft 12 (Fig. 1) seated rotor axially.
  • an annular disk 26 fastened with screws 27, which the rotor in the other axial Direction in the stator 11.
  • the chain 5 of the camshaft adjustment device is over the sprocket 6 performed (Fig. 1).
  • the ring gear 10 engages in a ring gear 28 of the intake camshaft adjuster 1 a (Fig. 1), with the stator non-rotatably connected, preferably integrally formed with it.
  • the ring gears 10, 28 advantageously have the same diameter.
  • the sprocket 6 can be easily opened in the manner described attach the stator casing 13.
  • the crankshaft 3 is over the chain 5 connected to the camshaft 12, which in turn via the gear transmission 10, 28 is drive-connected to the camshaft 29.
  • the Sprocket 10 and the sprocket 6 can be made of different materials be made so that an optimal adjustment in the material these parts are possible with regard to the application.
  • the camshaft adjuster has an intermediate shaft 30 which is parallel to Crankshaft 3 or the camshafts 12, 29 and a gear 31 rotatably supports that with the sprockets 10, 28 of the two camshaft adjusters 1, 2 is engaged. Also sits on the intermediate shaft 30 a chain wheel 32 for the chain 5. the crankshaft 3 thus drives the intermediate shaft 30 via the chain drive 4, 5, 32, which in turn, via the gear 31, the camshaft adjuster 1, 2 in drives the way described.
  • the gears 31 and 10, 28 have advantageously same diameter. But it is also possible that the gear 31 has a different diameter than the gear rings 10, 28 has, so that depending on the diameter ratio a step-up or step-down is possible.
  • This embodiment is also characterized in that it is cramped installation conditions can be easily installed.
  • the chain drive is only between the gear 4 on the crankshaft 3 and the gear 31 provided on the intermediate shaft 30.
