Definitions

  • the invention relates to a variable valve control for reciprocating internal combustion engines according to Preamble of claim 1.
  • Variable valve controls of this type are available Example known from DE 42 44 550 A1.
  • the intake valves controlling camshafts against each other is known in these Valve controls a four-wheel coupling gear provided its drive wheel with that of the crankshaft driven first camshaft and its driven gear with the one to be rotated relative to the first camshaft second camshaft is rotatably connected.
  • the drive connection between drive and driven gear manufactured via two intermediate wheels, which are coupled with each other and with the input and output gear are held.
  • Such a coupling gear requires in the area one end of the cylinder head of the internal combustion engine considerable space, since the paddocks themselves, the actuator acting on it and its drive and the idler wheels attached to the couplers outside the axes of the camshafts must be arranged.
  • the invention has for its object a Variable valve control in the preamble of the claim 1 shown in such a way that the Installation space for the adjustment gear between the opening and closing camshaft of the intake valves can be reduced can, the functional reliability with regard to the backlash in the variable speed gearbox, the construction effort is increased and thus reduces the cost of the variable speed gear and also a larger adjustment range is made possible.
  • each the ring gear firmly connected to the camshafts Combing the setting wheel with a second toothing his.
  • This second set of teeth on both adjusting wheels Camshafts mesh with each other so that a additional component for coupling the two camshafts is not required.
  • a reciprocating piston internal combustion engine 1 has Cylinder crankcase 2 and a cylinder head 3. in the Cylinder crankcase 2 is a crankshaft 4. In the cylinder head 3 are for actuating intake valves an opening camshaft 5 and a closing camshaft 6 and an exhaust camshaft for actuating the exhaust valves 7 stored. Is on the crankshaft 4 a drive wheel 8, which via a chain 9 with the camshaft drive wheel 10 on the opening camshaft 5 as well as with the camshaft drive wheel 11 on the exhaust camshaft 7 is connected.
  • the opening camshaft 5 and the closing camshaft 6 are with each other via an adjustment gear 12 connected.
  • the type of this connection is as follows described in more detail in the representation of the adjustment gear 12.
  • a servomotor acts on the adjustment gear 12 13, which is controlled by a control unit 14 becomes.
  • the control unit 14 processes, among other things Signals from sensors 15, which on phase wheels 16, the on the crankshaft 4 of the opening camshaft 5 and the Locking camshaft 6 are attached and their angular position detect.
  • the control device 14 can thus be known Way depending on the driver request and the other vehicle and engine parameters the optimal Opening parameters (start of opening, duration of opening, opening stroke) determine the intake valves and a corresponding one Give the command to the servomotor 13.
  • the servomotor 13 is an adjusting wheel 17th of the adjustment gear 12 so that the Opening camshaft 5 and the closing camshaft 6 in get an angular position to each other at which the optimal Opening parameters of the intake valves realized are.
  • This adjustment by means of the adjustment gear 12 takes place continuously during the motor operation of the Internal combustion engine 1.
  • each ring gear 18 of the adjustment gear 12 which has an internal toothing 19, non-rotatably attached.
  • Concentric to this ring gear 18 is an eccentric part on each of the two camshafts 5, 6 20 rotatably mounted.
  • Each of these eccentric parts 20 forms the respective axis 21 of the camshafts 5, 6 a bearing surface 22 eccentric by the dimension e about the eccentric axis 23.
  • Setting wheel 24 rotatably mounted.
  • the setting wheels 24 are each with a first toothing 25 of smaller diameter and with a second toothing 26 of larger diameter Mistake.
  • the toothing 25 with the smaller one The diameter is in engagement with the internal toothing 19 of the respective ring gear 18.
  • the larger toothings 26 both adjusting wheels 24 are in mutual engagement.
  • Each of the two eccentric parts 20 has a concentric extending to the axes 21 of the camshafts 5, 6 Adjustment teeth 27, which are designed as external teeth and is smaller in diameter than the toothing 26 of the adjusting wheels 24.
  • Adjustment teeth 27 both eccentric parts 20 engages a toothing 28 of the Adjustment wheel 17 a.
  • the two are via the two adjusting wheels 24 the intake valves actuating camshafts 5, 6 rotatably connected. That coming from the opening camshaft 5 Torque comes from the internal toothing 19 of the ring gear 18 of this shaft 5 on the first toothing 25 of the the opening camshaft 5 located adjusting wheel 24 and is on the second gear 26 on the Transfer camshaft 6 located adjusting wheel 24, whose first toothing 25 with the inner toothing 19th of the ring gear 18 of the locking camshaft 6 in engagement stands.
  • the two eccentric parts 20 do not run with um. However, you can use the adjusting wheel 17 via the adjusting teeth 27 in the same direction around the respective Axis 21 of the camshafts 5, 6 are rotated.
  • the eccentric axis 23 moves on one Track 29 about the axis 21 of the corresponding camshaft 5, 6 ( Figure 3 and Figure 4).
  • FIGS 3 and 4 in which the partial circles the internal gears 19 of the ring gears 18 and the gears 25, 26 of the adjusting wheels 24 are shown the adjustment process of a camshaft 6 compared to the other camshaft 5.
  • FIG. 3 shows an initial position, where the position of setting wheels 24 and ring gears 18 with the brands 30, 31, 32, 33 and 34 in one Line is marked.
  • the opening camshaft 5 is held by like-minded Twisting the two eccentric parts 20 by a certain one Angle of rotation enter a position according to Figure 4, in which the eccentric axes 23 on the track 29 moved through 90 ° are. It has on the side of the opening camshaft 5 the teeth 25 of the adjusting wheel 24 on the internal teeth 19 of the ring gear 18 so that the marking 30 by a certain angle from the straight line is deflected. To the same extent is on the larger The diameter of the second toothing 26 marks 31 deflected.
  • This deflection is also the on the toothing 26 of the adjusting wheel 24 on the side of the Closing camshaft 6 located mark 32 deflected. Around is the same angular amount as the mark 32 the mark 34 deflected. Due to the resulting shifting the teeth 25 on the internal teeth 19 the side of the closing camshaft 6 is the mark 33 and so that the closing camshaft 6, opposite the opening camshaft 5 twisted by a certain angle.
  • This adjustment process is also with rotating Camshafts 5, 6 in both directions in any size Adjustment range possible.
