Definitions

  • the invention relates to a variable valve control device for internal combustion engines of Hubkolbenbauart with at least one gas exchange valve which is actuated by means of a rotatably mounted about a camshaft axis via a cam rotatably connected to the camshaft, at least two different cam tracks cam device, wherein by means of a control device optionally one of the cam tracks activated and at least one other cam track is deactivatable, and wherein the control device has at least one axially guided in particular within the camshaft actuator of which by means of at least one driving piece at least one rotatably but axially displaceably mounted on the camshaft, at least two different cam tracks having cam device is adjustable.
  • a valve train of an internal combustion engine in which a cam is rotated with different cam tracks of a camshaft.
  • the cam can be moved axially on the camshaft to realize different valve lifts.
  • the adjustment required for the displacement is arranged in the interior of the camshaft.
  • the movement of the adjusting member is transmitted to the axially displaceable cam via a spring element, which is also guided in the interior of the camshaft. Since the axial displacement of the cam is possible in virtually every rotational position of the camshaft, damage to the cam tracks or transmission devices can not be excluded.
  • DE 199 08 286 A1 describes a variable valve control device for internal combustion engines, which comprises valves for gas exchange control, which are actuated by means of a camshaft.
  • the camshaft has an actuator shaft with an actuator and relatively movable cam devices. Each cam device is mounted axially movable on the stator shaft. Between the cam device and the actuator shaft, a spring device is provided, which seeks to move the cam device in the home position.
  • the cam device cooperates with a triggering device which is provided with a fixedly mounted on the actuator shaft control ring and a radially arranged to the actuator shaft locking pin.
  • the control ring has a control cam, which is in operative connection with a compression spring locking pin has a control projection.
  • the control cam engages under the control projection in response to an axial position and a radial position of the actuator shaft and lifts after a partial rotation of the actuator shaft to the locking pin, whereby the cam device performs an axial movement in a defined operating position.
  • the spring device holds the cam device in a basic position, from which the actuator shaft moves this cam device as a function of parameters of the internal combustion engine in a defined operating position.
  • the functionally correct movement of the cam device ensuring release device is only effective when the actuator shaft is in defined position settings.
  • the disadvantage is that an additional control effort is necessary for the operation of the triggering device.
  • the object of the invention is to avoid the disadvantages mentioned and to enable the simplest possible way a reliable and fail-safe variable valve actuation.
  • the blocking element for blocking or releasing the axial adjusting movement of the cam device, the blocking element having a control pin fixedly connected to the cam device and a control disk arranged coaxially with the camshaft, preferably fixed, the control disk has at least one control opening for receiving the control pin in at least one angular range.
  • the control disk can be arranged fixed to the housing.
  • the blocking or release of the displaced movement of the cam device is purely mechanical by the arrangement of the control opening on the control disk and the interaction of the control pin with the control port. This can be dispensed with a complex control.
  • the invention has the advantage over the prior art known from DE 199 08 286 A1 that parts and installation space can be saved.
  • control pin is radially projecting on the cam device, preferably arranged on an outer jacket of the cam device.
  • the control pin is fixed, ie immovable, connected to the cam device, and projecting radially outwardly provided on the outer jacket of the cam device.
  • the control pin can for example be pressed into a radial bore of the cam device, glued or screwed.
  • control opening is arranged in a wall of the control disk facing the cam device, which is formed, for example, normally normal to the axis of rotation of the camshaft.
  • a simple production of the control opening is possible if this is designed as a wall breakthrough.
  • the control opening can-viewed in the frontal view-have substantially the shape of a circular segment or a circular ring segment, it being particularly advantageous if the control opening extends over an angular range of at least 60 °, preferably at least 90 °.
  • control disk is exposed on both sides of the wall. This prevents collisions of the locking pin with adjacent elements.
  • control opening and the control pin are arranged relative to each other in such angular ranges of the control disk or the camshaft, that the cam device is adjustable only in valve hubleless state, preferably the base circles of the cam tracks a Hubübertragungselement facing.
  • FIG. 1 shows a variable valve control device according to the invention in an oblique view in a longitudinal section in a first displacement position.
  • valve control device in a longitudinal section in the first
  • valve control device in another oblique view in the first displacement position.
  • valve control device 4 shows the valve control device in a further oblique view in the first displacement position
  • valve control device in an oblique view in one
  • valve control device in a longitudinal section in the second displacement position.
  • FIG. 7 shows the valve control device in another oblique view in the second displacement position
  • valve control device 8 shows the valve control device in a further oblique view in the second displacement position
  • valve control device in a side view.
  • the figures show a variable valve timing device 1 for internal combustion engines with at least one rotatably mounted about a camshaft axis 2 camshaft 3, wherein a cam device 4 with at least two cams 5, 6 and cam tracks 7, 8 with the camshaft 3 rotatably, but axially slidably connected.
  • the cam device 4 acts on a transmission element 30 of a stroke transmission device 31, for example a valve lever, designed as a roller body, which stroke transmission device 31 actuates at least one gas exchange valve of the internal combustion engine which is not further illustrated in the figures.
  • one of the cam tracks 7, 8 can be activated or deactivated via a control device 10.
  • the control device 10 has at least one axially guided within the camshaft 3 actuator 11, with which a formed by a radial pin driving piece 12 is firmly connected.
  • the actuator 11 is formed as a piston, which is guided in a coaxial with the camshaft axis 2 arranged guide cylinder 13 of the camshaft 3 longitudinally displaceable.
  • the driving piece 12 penetrates in the radial direction a slot 16 of the camshaft 3 and is embedded in a radially extending bore 17 of the cam device 4.
  • the cam device 4 is thus connected via the driving piece 12 with the actuator 11, so that the axial displacement movement of the actuator 11 is transferred between a first displacement position and a second displacement position on the cam device 4.
  • either the first cam 5 or the second cam 6 of the cam device 4 can be selectively activated by bringing the first cam track 7 and the second cam track 8 into engagement with the transmission element 30 of the stroke transmission device 31.
  • the displacement of the cam device 4 can be carried out with minimal expenditure of force in the valve-lift-free state, that is to say when the base circles 7a, 8a of the cam tracks 7, 8 face the transmission element 30 of the stroke transmission device 31.
  • a blocking element 20 is provided.
  • the locking member 20 has a fixedly connected to the cam device 3 control pin 21 and a coaxial with the camshaft 3 arranged housing-fixed control disk 22.
  • the control pin 21 is radially projecting from a cylindrical outer shell 18 of the cam device 4.
  • the control disk 22 has on the cam device 4 side facing a normal to the camshaft axis 2 arranged or extending wall 23, in which a wall opening 24 is formed.
  • the wall opening 24 formed in the exemplary embodiment as a circular ring segment forms a control opening 25 corresponding to the control pin 21 and extends over the camshaft axis 2 over a defined angular range ⁇ , wherein in the exemplary embodiment the angular range ⁇ is approximately 130 ° (FIG. 9).
  • control opening 25 and the control pin 21 are arranged relative to each other in such angular ranges of the control disk 22 and the camshaft 3 that the cam device 4 is adjustable only in a valve-free state, ie when the base circles 7a, 8a of the cam tracks 7, 8 of the stroke transmission device 31 are facing.
  • the wall 23 has a thickness b which substantially corresponds to the thickness d of the control pin 21 - measured in the direction of the camshaft axis 2.
  • the control disk 22 is free on both sides of the wall 23, so that an unobstructed rotation of the control pin 21 about the camshaft axis 2 is possible.
  • FIGS. 1 and 2 show the cam device 4 in a first displacement position, wherein the first cam 5 with the first cam track 7 is activated.
  • the actuator 11 is pressed by the actuator 14 in Figs. 1 and Fig. 2 to the left, ie in a direction away from the blocking member 20 direction.
  • the basic circuits 7a, 8a face the transmission element 30 of the stroke transmission device.
  • the control pin 21 is located in the region of the control opening 25, so that the axial adjustment movement of the cam device 4 through the locking member 20 - according to the activation of the actuator 14 - is released.
  • FIGS. 3 and 4 likewise show the cam device 4 in the first displacement position, the first cam 5 with the first cam track 7 being activated.
  • the cam 5 is here but in its stroke position - an axial adjustment of the cam device 4 would be undesirable here.
  • the axial adjustment in this camshaft position is blocked by the locking member 20 by the control pin 21 moves to the wall 23 of the control disk 22. It can clearly be seen in FIGS. 3 and 4 that the control pin 21 is in its lower position, which is diametrically opposite the control opening 25 with respect to the camshaft axis 2, and thus bears against the wall 23.
  • the cam device 4 is in a second displacement position, the second cam 6 with the second cam track 8 being activated.
  • the actuator 11 is pressed by the arranged within the camshaft 3 restoring spring 15 with deactivated actuator 14 in Figs. 5 and Fig. 6 to the right, ie in the direction of the locking member 20.
  • the basic circuits 7a, 8a here too face the transmission element 30 of the stroke transmission device.
  • the control pin 21 is thus located in the region of the control opening 25, so that the axial adjustment cam device 4 through the locking member 20 - according to the activation of the actuator 14 - is released.
  • the cam device 4 is still in its second displaced position - yet or already initiating a valve lift of the corresponding gas exchange valve, although the adjustment movement of the cam advancer is still in its second displacement position.
  • direction 4 locked by the actuator 14 in the first displacement position by the locking member 20, since the locking pin 21 is outside the control opening 25 and thus rests against the wall 23. Only when the control pin 21 is rotated by the camshaft 3 in an upper position seen in the figures and - viewed in a projection in the direction of the camshaft axis 2 - within the control opening 25, the adjusting movement is released from the second to the first displacement position ,
  • the blocking member 20 allows easy activation of the activator 14, since it can be activated or deactivated independently of the respective rotational position of the camshaft 3.
