Definitions

  • the present invention relates to an actuating element for axially displacing a displaceably mounted camshaft or a camshaft section displaceably mounted on a shaft along the camshaft axis. Furthermore, the invention relates to a device for axially displacing a camshaft or a camshaft section, comprising an axially displaceable camshaft or an axially displaceable camshaft section, which or has one or more projections, and such an actuating element.
  • Camshafts have a number of cams that represent eccentric portions on the camshaft.
  • the cams can either be fixedly arranged on the camshaft or on camshaft sections which can be applied in a rotationally fixed but axially displaceable manner to a cylindrical shaft. With the cams adjacent axially displaceable components can be moved by turning the camshaft at regular intervals.
  • a prominent application of the camshafts is thereby the opening and closing of valves in an internal combustion engine.
  • it is possible to change the engine characteristics for example, from a comfort-oriented to a sporty characteristic, which, inter alia, by changing the valve lift caused by the Shape of the cam is determined, is implemented.
  • different engine speeds require variable valve lifts to optimize torque and fuel consumption.
  • FIG. 1 A camshaft portion for such a camshaft is in FIG. 1 shown whose lateral surface can be divided into three sections. In a first section is a first cam, which opens a valve of an internal combustion engine with a first lift curve.
  • a second section is a second cam, which is smaller in comparison to the first cam and has a different geometry, and thus the valve during rotation of the camshaft with a second lift curve compared to the first lift curve less far and for a shorter time with a other speed profile opens.
  • a valve which cooperates with the first section is not actuated at all during rotation of the camshaft, which is the case, for example, when the cylinder is switched off.
  • the in FIG. 1 shown camshaft portion each has two of these sections, so that two of these camshaft sections must be provided for a four-cylinder internal combustion engine.
  • the camshaft or the camshaft section must be moved axially to allow each of the corresponding cam to interact with the valve.
  • the camshafts on different grooves, in which engages an actuator with a different number of plungers.
  • the grooves are doing a guide portion and together with the engaging rams form a slotted guide for the axial adjustment of the camshaft, which must be rotated by a certain amount for this purpose.
  • the actuators Since the plungers of the actuators have to be moved back and forth coordinated with each other, the actuators are constructed relatively complicated.
  • the grooves must be milled into the camshaft, which is therefore particularly associated with a considerable manufacturing effort, since a separate groove is provided for each plunger, which also each have their own cross-section.
  • the camshaft is weakened in the area in which the grooves are arranged, which increases the likelihood of breakage in this area. This probability is increased by voltage spikes caused by the grooves.
  • Object of the present invention is therefore to provide an arrangement with which a camshaft can be moved axially in a structurally simple manner.
  • the adjusting element is movable between a first position and a second position, wherein the actuating element has a guide portion, cooperate with the one or more projections of an axially displaceably mounted camshaft or an axially displaceably mounted camshaft portion in the first position so that the camshaft or the Camshaft portion is axially displaceable by rotating about the camshaft axis, and the projection in the second position does not cooperate with the guide portion.
  • the actuator can be brought into other positions.
  • the decisive factor is that at least in one position the projections can interact with the actuator and in another Position no interaction is possible.
  • An essential aspect of the present invention is that the guide portions are not arranged on the camshaft itself, as is the case in the prior art, but on the actuator.
  • the actuator can be designed so that even guide sections with a more complicated geometry can be made relatively easy.
  • the camshaft itself need not be provided with grooves or the like, but it is sufficient to provide a projection which cooperates with the guide portion of the actuating element when this is in the first position.
  • the production of the camshaft is significantly simplified, so that an axial displacement of the camshaft or the camshaft section can be realized in a particularly cost-effective manner.
  • the camshaft is not weakened by grooves, so that it is more stable overall and the likelihood that the camshaft breaks, is reduced.
  • the axial displacement of the camshaft or the camshaft section takes place in the following manner:
  • the actuator is moved to the first position, in which the projection cooperates with the actuating element.
  • the camshaft is rotated by a certain amount, for example, 90 °, wherein the projection moves along the guide portion so that the shape of the guide portion dictates the amount and motion profile of the axial displacement of the camshaft or camshaft portion along the camshaft axis.
  • the actuator is moved to the second position and the camshaft can be used as intended.
  • the guide portion comprises one or more guide surfaces of the actuating element, which are at least partially inclined with respect to a central plane of the actuating element.
  • the middle plane is supposed to do so run that it divides the actuator into two substantially equal halves.
  • the guide surfaces are the outer surfaces of the actuating element, which limit the actuating element to the outside. The guide surfaces thus enclose an angle with the median plane.
  • the guide section comprises a first guide surface and a second guide surface, wherein the first guide surface and the second guide surface are inclined in opposite directions with respect to the center plane.
  • a first projection cooperates with the first guide surface, whereby the camshaft or the camshaft section is displaced axially in the first direction.
  • a second projection cooperates with the second guide surface, whereby the camshaft or the camshaft portion is axially displaced in the opposite direction.
  • the two projections can be arranged axially spaced on the camshaft. Between the two adjustment steps, the adjusting element is moved to the second position.
  • the guide section has one or more guide grooves, which are inclined at least in sections relative to a center plane.
  • the guide grooves have the advantage that they can transmit axial forces relative to the camshaft axis along both directions. As a result, a forced operation or a slotted guide is realized.
  • the guide portion has a first guide groove and a second guide groove, wherein the first guide groove and the second guide groove are inclined in opposite directions with respect to the center plane.
  • first guide groove and the second guide groove are inclined in opposite directions with respect to the center plane.
  • the first guide groove and the second guide groove intersect.
  • the camshaft can be displaced axially by turning in the same direction with a projection both one and in the opposite direction.
  • the two guide grooves can be designed so that the projection is axially positioned after passing through the first guide groove, that it then engages in the second guide groove, without the actuator must be axially displaced or a second projection must be provided.
  • a very compact actuator can be provided, which allows the displacement of the camshaft or the camshaft portion in both directions with only one projection, without the actuator must be arranged axially displaceable. Consequently, a very cost-effective and mechanically simple camshaft displacement can be realized.
  • the first guide groove has a first cross section and the second guide groove has a second cross section which differs from the first cross section.
  • This embodiment is particularly suitable when a plurality of first guide grooves and a plurality of second guide grooves are provided.
  • the actuator can be moved a little further to the camshaft, for example, during axial advancement of the camshaft or the camshaft portion, so that the projection of the deeper groove is clearly guided even at crossing points.
  • the actuator is moved slightly less far to the camshaft, so that the projection is guided only by the less deep groove and does not intervene in the deeper groove at the intersection. Consequently, then there are several first positions in which the projection can interact only with a specific groove. Alternatively, multiple protrusions of different sizes may be used.
  • the guide grooves have a first end and a second end, wherein the guide grooves in the region of the first end have an initial depth and leak in the region of the second end to zero.
  • the depth of the guide groove should be gradual lose weight.
  • the actuator is displaced from the projection itself from the first position toward the second position when the projection passes through the guide grooves. This allows a purely mechanical return to the second position can be achieved. Furthermore, it is prevented that the projection abuts against the groove end and is thus subjected to shear, which could lead to breakage of the projection. In addition, this ensures that the projection is no longer guided by the guide grooves when the camshaft or the camshaft portion has been moved to the desired axial position. It is prevented that tilted due to manufacturing inaccuracies or misalignment of the projection in the groove and consequently the actuator could be reset only with increased force in the second position or even blocked.
  • the adjusting element has a storage section, with which the adjusting element between the first position and the second position is rotatably storable.
  • the rotatable mounting has the advantage that the mounting can be kept simple and the adjustment path particularly short. In addition, only very small adjustment forces are necessary for moving the actuating element in this embodiment.
  • the actuating element has a tubular curved section, in which the guide section is arranged.
  • the cooperating with the actuating elements projection of the camshaft or the camshaft section moves on a circular path.
  • the guide section In order for the projection to interact with the guide section, the guide section must also follow this circular path at least in sections.
  • the actuator provided with a tubular curved portion the adjusting element can be made to save material and be brought in the first position particularly close to the camshaft.

  • the projection which may be formed as a pin or pin, be stored or have a bearing engagement element with which it cooperates with the actuating element in order to reduce the forces and moments acting on the projection.
  • Such a configuration of the projection can also be provided for the adjusting element according to the invention, but is in any case structurally complex.
  • the actuator is provided with a tubular curved portion, the projections for the reasons mentioned above only have to protrude radially over the camshaft over a short distance, which significantly reduces the risk of breakage due to bending and shearing loads, so that no additional measures for reducing the loads are required.

  • FIG. 3 is the actuator 24 1 in the second position, so that neither of the two pins 40, 42 cooperates with the actuator 24 1 . If the plunger 44 is displaced from the actuator 45 to the camshaft axis A N toward the first position, one of the two pins 40, 42 cooperates either with one of the guide surfaces 32 or one of the guide grooves 34. In both cases, the pins 40, 42 pass through the guide surfaces 32 or the guide grooves 34 from the bearing portion 28 to the actuating portion 45 when the camshaft portion 10 is rotated approximately 90 degrees.
  • one of the pins 40, 42 slides along one of the guide surfaces 32 or one of the guide grooves 34, thereby selecting a force acting along the camshaft axis A N on the respective pin 40, 42 due to its inclination with respect to the center plane E not shown is applied, so that the camshaft portion 10 is axially displaced along the camshaft axis A N.

  • the pin 42 then engages the left of the first guide grooves 34 1 , so that the camshaft portion 10 is further axially displaced in the same direction that the portion 18 3 cooperates with the valve.
  • camshaft section 10 If the camshaft section 10 is to be pushed back axially, then either the first pin 40 is used by a corresponding rotation of the camshaft section 10, which protrudes a little further beyond the lateral surface 14 in comparison to the second pin 42, or the actuating element 24 1 becomes slightly further on Camshaft section 10 moved up and brought back the second pin 42 into engagement. This ensures that the pins 40, 42 are guided only by the lower second guide grooves 34 2 . A further axial displacement of the camshaft section 10 can also take place via the guide surfaces 32 1 and 32 2 .
  • the guide grooves 34 extend to zero with increasing distance from the rotation axis A D. As a result, a radius reduction of the guide grooves 34 is achieved, which has the effect that the actuator 24 1 is rotated away from the camshaft portion 10 when one of the pins 40, 42 passes through the guide grooves 34.
  • the guide grooves 34 and the Pins 40, 42 may be designed so that the actuator 24 1 is already in the second position when the pins 40, 42 have completely passed through the guide grooves 34.
  • the force acting on the actuator 24 1 weight force to move between the first and the second position by a corresponding arrangement of the actuating element 24 2 with respect to the camshaft portion 10 can be exploited.

  • the actuator may also include a bistable solenoid.
  • FIG. 4 is a second embodiment of the device according to the invention 36 2 shown with an actuating element 24 2 according to a second embodiment with reference to a perspective view.
  • a first and a second cam section 10 1, 10 2 are pushed onto the manner not shown rotatably mounted shaft 15, and together form the essential parts of a camshaft.
  • the camshaft axis A N and the axis of rotation A D are parallel to each other.
  • the adjusting element 24 2 is configured slightly wider according to the second embodiment, wherein the tubular curved portion 26 in turn covers an angle of about 90 °.
  • the two camshaft sections 10 1 , 10 2 are moved axially with the same actuator 24 2 .
  • the axial displacement The camshaft sections 10 1 , 10 2 along the camshaft axis A N is done in the manner described above.
  • FIG. 5 a third embodiment of the actuator 24 according to the invention 24 3 is shown with reference to a perspective view.
  • the tubular curved portion 26 has a first subsection 50 and a second subsection 52, each sweeping an angle of approximately 90 °, so that the actuator 24 3 according to the third embodiment a Angle of 180 ° sweeps over, so that the actuator 24 3 has the shape of a groove or half-shell.
  • the storage section 28 is located approximately in the middle of the tubular arched portion 26, where the two subsections 50, 52 abut one another.
  • FIG. 6 shows a third embodiment of the inventive device 36 3 with the in FIG. 5 shown actuator 24 3 , which cooperates with a camshaft portion 10.
  • the camshaft section 10 has two pins 40, 42 which are in FIG. 6 are not recognizable and contrary to the in FIG. 3 embodiment shown are not aligned.
  • the actuator 24 3 is in the second position when the first subsection 50 and the second subsection 52 have the same distance to the camshaft section 10, so that the actuator 24 3 with none of the two pins 40, 42 cooperates.
  • the actuator 45 pulls the plunger 44 towards itself, the actuator 243 is rotated in a first direction about the axis of rotation A D and the first subsection 50 of the tubular arched portion 26 cooperates with the in FIG. 6 rear pin 40 together.
  • the actuator 243 When the actuator 45 pushes the plunger 44 away from itself, the actuator 243 is rotated in the opposite direction about the axis of rotation AD, so that the front Pin 42 engages in the guide grooves 34 of the second subsection 52 of the tubular arched portion 26. Due to the rocker-like movement of the actuating element 24 3 , the second position is an intermediate position between the end positions of the actuating element 24 3rd The axial displacement of the camshaft portion 10 along the camshaft axis A N also happens here in the manner described above.
  • a shift is also possible in other ways: Depending on the configuration of the actuator 45, the zero position of the plunger 44 may be in the second position of the actuating element 24 3 when the actuator 45 is not activated. Consequently, the actuator 45 must be activated to rotate the actuator in one direction or the other about the axis of rotation A D. However, it is also possible to design the actuator 45 in such a way that, when the actuator 45 is not activated, the actuating element is set to the first position, in which the rear pin 40 interacts with the first subsection 50. If no interaction takes place, then the actuator 45 must be activated so that it advances the plunger 44.
  • the actuating element 24 3 can be rotated such that the rear pin 40 also interacts with the actuating element 24 3 in the second subsection 52. Consequently, the rear pin 40 can not only pass through the first, but also the second subsection 52, so that a very large axial displacement of the camshaft or the camshaft section 10 is made possible with only one pin 40.
  • a magnet may be formed pressing, which rotates the pin in a cam. The pin then turns towards lane 26 and 50 and should not be engaged. The magnet is pressed. The half shell with adjustment track is not engaged. If the adjustment pin passes through the axis of rotation 28, it can be inserted into the corresponding track on the second quarter shell and displaces the cam, for example, to the left. If the actuator is not actuated when meshing on the first half-shell in tracks 26 and 50, it is for example pushed to the right. Analogously, this happens with pulling variants.
