Definitions

  • the invention relates to an actuator for an internal combustion engine with an actuator consisting of an electromagnetic circuit having a coil, a fixed core, a movable armature and a yoke, a plunger which is actuated via the electromagnetic circuit and which is connected to the armature and a permanent magnetic circuit consisting of the yoke, the core, the armature and a permanent magnet which holds the armature in a Walkerend ein in the de-energized state of the electromagnetic circuit, wherein the permanent magnet is disposed stationary within the electromagnetic circuit and means for concentrating axial magnetic Field lines are formed on the permanent magnetic circuit.
  • Such actuators are used for example for adjusting sliding cam contours on which different lifting profiles are formed and which are arranged displaceably on a camshaft.
  • the actuator engages in a groove of the sliding cam. After the axial adjustment resulting therefrom, the actuating element is normally passively returned to its starting position via a lifting contour of the groove.
  • Such an actuator is for example from the WO 03/021612 A1 known.
  • the actuator of the electromagnetic actuator described herein is formed by a plunger which is engageable with the sliding cam groove.
  • the adjusting device has a permanent magnet which is firmly connected to the plunger and the magnetic force of the plunger in its retracted position is held.
  • the field of the permanent magnet is so far weakened that the holding force is less than a force which is exerted in the extension direction of the plunger via a spring element on the plunger, so that the plunger is moved into the groove.
  • a lifting contour of the plunger is moved back to its original position.
  • an electromagnetic actuator which is held in an end position by a permanent magnet and in its other end position by a spring force.
  • an annular shoulder is formed, into which an anchor plate of the actuator dives. This shoulder has a smaller width than the rest of the yoke and serves to bundle the magnetic field lines.
  • an actuator having the features of the main claim, characterized in that the armature has a radially réellede armature plate and in its interior a cavity, said first means for focusing the magnetic field lines extending through a yoke axially towards the armature plate An extension of reduced thickness are formed, which surrounds the armature plate at least partially radially in the Garend ein and second means for concentrating the magnetic field lines are formed by an axially extending towards the armature portion of the core, which protrudes in the Halteend ein in the cavity of the armature and wherein either the armature plate in the holding end position spaced from the yoke is arranged or the armature in the holding end position spaced from the core, on the one hand, the force acting in the direction of movement of the plunger permanent magnet force is increased, whereby the plunger already at a greater distance to übri gen permanent magnetic circuit is tightened and on the other hand, by this gap, the holding force of Permanent magnet so reduced that a release of
  • the otherwise very high magnetic forces are thus reduced in order to use smaller electromagnet or a lower current to release the holding force can.
  • a mechanical load of the permanent magnet due to shocks so that its functionality is ensured over a long period of time.
  • the mass to be moved is very small, so that no high actuating forces must be applied.
  • the anchor plate serves to close the magnetic circuits, wherein the permanent magnetic circuit can be closed only in the holding position.
  • the magnetic field lines are bundled out of the yoke. Due to the small thickness of the extension, the field lines also mainly have an axial direction.
  • this focused field acts on the anchor plate already when the anchor plate is still at a distance to its support point, since depending on the height of the extension and the magnetic force acts on the extension on the anchor plate, so that a corresponding distance to the support surface are overcome can.
  • the axially extending into the cavity of the armature portion on the core has substantially the same effect as the axially extending projection on the yoke.
  • field lines are bundled in the axial direction and guided into areas which reduce an axial distance between the parts of the magnetic circuit to exert a force from the armature at a distance of about 1mm from the holding end position, this in the direction of its Garend ein emotional. Due to the cavity in the anchor, the weight of the anchor is reduced, so that inertial forces and thus required holding and adjusting forces fall and faster actuation is possible.
  • the permanent magnet is arranged axially between the core and the yoke, and the core and the permanent magnet are arranged radially spaced from the yoke. Due to the axial arrangement of the permanent magnet is a mechanical shock load of which excluded. Due to the radial distance between the magnet or the core and the yoke, a violation of magnetic field lines in the radial direction in the permanent magnetic circuit is avoided. Thus, a bundling of axial magnetic field lines takes place, since the magnetic field can continue only in this direction. This leads to an increased magnetic force in the axial direction, ie in the direction of movement of the plunger with a constant large magnet.
  • a spring element is arranged in the cavity of the armature, which rests against a stop formed in the interior of the armature and against the core.
  • the diameter of the permanent magnet is greater than the free diameter in the interior of the bobbin and the permanent magnet is arranged on the end facing away from the plunger of the coil.
  • a support surface for the armature plate is formed in the housing in its second end position, wherein in the support surface at least one additional permanent magnet is arranged.
  • an additional holding force can be generated in the second end position, the magnetic field is also available for bearing feedback.
  • a non-contact sensor is arranged in a housing of the actuator, via which a changing with movement of the armature plate magnetic field is detected.
  • This field change causes a different output signal of the sensor whose size is a measure of the position of the plunger.
  • both changing field line directions and strengths can be used for position measurement.
  • the movable anchor plate generates a field change during their movement.
  • two adjusting elements are arranged side by side in the housing.
  • the first adjusting element to move the cam in a first direction and the second actuator to move the cam in the opposite direction. Accordingly, an actuation only one of the actuating elements is necessary and desired.
  • Their arrangement in a common housing simplifies assembly and reduces the required space.
  • the non-contact sensor is arranged on an axis of symmetry of the two control elements in the housing, which is operatively connected to two actuators, each actuator is associated with an additional permanent magnet, wherein the two permanent magnets are polarized opposite to the sensor operatively connected. Due to the position of the sensor, it is thus possible to detect the position of both control elements with only one sensor due to the different direction of the field lines. Accordingly, the number of components used is reduced compared to known designs.
  • an actuator which can apply a sufficient force to tighten the plunger from a distance of about 1mm to the end position. Nevertheless, the holding force in this end position remains such that a release by means of a normal electromagnet remains possible.
  • Several such control elements can be arranged in a common housing and their position can be detected by means of a common position sensor.
  • the inventive Actuator requires only a small space due to its small size. It has a high durability due to the low mechanical load of the permanent magnet.
  • FIG. 1 illustrated actuator 2 of an actuator according to the invention consists of an electromagnetic circuit 4, a plunger 6 which is actuated via the electromagnetic circuit 4 and a permanent magnetic circuit 8 for generating a holding force in a holding end position of the plunger. 6
  • the electromagnetic circuit 4 has a coil 10 which is surrounded by a yoke 12 and in the interior of which an axially movable armature 14 is arranged, which is fixedly connected to the plunger 6 so that it is moved with movement of the armature 14.
  • the armature 14 is designed as a hollow cylinder, from which an armature plate 16 extends radially outwardly and which has a recess 18 in which the plunger 6 is fixed by welding.
  • a spring element 22 is arranged in the form of a helical spring, with its first end against a purely in FIG. 2 illustrated paragraph 24 of the armature 14 or the plunger 6 is supported and with its second end is supported against a core 26 which is arranged in the present embodiment in a bobbin 28.
  • the outer diameter of the armature 14 moves with play within a coil carrier 28.
  • the leadership of the plunger 6 takes place in a turn only in FIG. 2 shown guide housing part 30 which radially surrounds the plunger 6 in the axial direction of extent.
  • the permanent magnetic circuit 8 consists of a permanent magnet 32, which is arranged axially between the core 26 and a radially extending portion of the yoke 12 and radially inside of the coil carrier 28, and the yoke 12, the armature 14 and the core 26th
  • the core 26 has three sections axially one behind the other.
  • a first axially extending portion 34 has a cylindrical shape with a shoulder, so that two cylinders axially behind each other arise, and protrudes into the hollow cylindrical armature 14, wherein the outer diameter of the portion 34 in the region of the larger portion is slightly smaller than the inner diameter of the Cavity 20.
  • a second cylindrical portion 36 of larger diameter which has substantially the same diameter as the armature 14.
  • There follows a third portion 38 which has a diameter growing in the opposite direction to the plunger until this diameter corresponds to the diameter of the permanent magnet 32.
  • the entire core 26, the permanent magnet 32 and the armature 14 are surrounded by the bobbin 28 made of plastic.
  • the bobbin 28 thus extends in the opposite direction to the plunger axially over the coil 10 away until the axially delimiting portion of the yoke 12.
  • the coil support 28 by the coil support 28, the radial distance between the core 26 and the permanent magnet 32 and the axially extending yoke 12 held so great that trespassing magnetic field lines is avoided as completely as possible, whereby a bundling of the existing magnetic forces is achieved.
  • a radially inwardly extending portion is formed on the yoke 12 at the end facing the plunger, which serves as a conclusion. From this section extends axially in the direction of the anchor plate 16, an annular extension 40 which surrounds the armature plate 16 radially in the holding position.
  • the armature 14 In its initial position, which corresponds to the retracted position or the holding end position of the plunger 6, the armature 14 bears against the core 26 with its first axial end. In this position, the armature 14 and thus the plunger 6 is held by the permanent magnetic circuit 8 whose field lines from the permanent magnet 32 via the yoke 12 in the armature plate 16 and the armature 14 and back over the core 26 to the opposite pole of the permanent magnet 32. It is accordingly a closed magnetic field, which exerts a holding force on the armature 14 which is greater than a spring force acting in the opposite direction, which exerts the spring element 22 on the armature 14.
  • the existing holding force is particularly dependent on existing gaps in the permanent magnetic circuit 8.
  • the axially extending portion of the armature 14 is formed slightly longer than the distance between the support surface of the armature 14th at the core 26 and the lower edge of the yoke 12 without the annular extension 40. This results in a gap 42 between the radially inwardly extending portion of the yoke 12 and the armature plate 16 in the Halteend ein.
  • the plunger 6 must be moved to an extended state.
  • a magnetic field is generated by the electromagnetic circuit 4, which acts counter to the magnetic field 8 of the permanent magnet. This leads to a weakening of the force acting between the armature 14 and the core 26 holding force until finally the spring force is greater than the holding force, whereby the armature 14 is released from the core 26. It follows under the action of the spring force, a movement of the armature 14 and thus the plunger 6, in which they move from the core 26 in its second extended end position. For this purpose, no electromagnetic force is required in this embodiment.
  • the plunger 6 slides in this state with its pointing out of the actuator end in a groove of the sliding cam and moves it to the desired position.
  • These grooves are formed so that at the end of the rotation of the plunger 6 is actively raised by a survey of the groove, so that the plunger 6 and the armature 14 are moved in the direction of the holding end position.
  • the stroke of the groove is made slightly smaller than the stroke of the armature 14. This is required due to installation tolerances, otherwise there would be a risk of jamming of the camshaft.
  • the existing gap in this position must be bridged in order to hold the armature 14 in its final position, if possible without having to activate the electromagnetic circuit 4. Accordingly, the magnetic force necessary for this purpose should be applied by the permanent magnetic circuit 8. For this purpose, it is necessary to generate permanent magnetic magnetic lines acting in the axial direction already at a distance of about 1 mm between the armature 14 and the core 26.
  • the axially extending portion 34 of the core 26 serves as an additional measure for bundling the permanent magnetic axially acting field lines.
  • the entire field lines of the permanent magnet 32 are bundled by the shape of the core 26 narrowing in the direction of the armature 14, so that here too high axial magnetic forces occur between the core 26 and the armature 14.
  • the in FIG. 2 shown actuator differs from that in FIG. 1 represented in particular in that two adjusting elements 2a, 2b are arranged side by side in a common housing 44, wherein the first adjusting element 2a is shown in its second end position and the second adjusting element 2b is shown in its holding end position.
  • the core 26 extends over the entire axial length of the bobbin 28, so that the armature plate 16 serves to close the magnetic circuits 4, 8.
  • the armature plate 16 serves to close the magnetic circuits 4, 8.
  • this embodiment also extends an extension 40 from the yoke 12 in the direction of the anchor plate 16.
  • a cylindrical portion 34 of the core 26 extends into the cavity 20 of the armature.
  • the gap 42 is formed in this embodiment between the armature plate 16 and the core 26 in the holding end position, while the armature plate rests against the yoke 12.
  • FIG. 3 a possibility for the arrangement of the non-contact magnetic sensor 46 can be seen.
  • This is arranged on an axis of symmetry 50 between the two adjusting elements 2a, 2b.
  • This arrangement has the advantage that both adjusting elements 2a, 2b can be monitored via the magnetic sensor 46 or their position can be detected.
  • four small bar magnets 45 serve here in the guide housing part 30, in the region of the abutment of the armature plate 16, wherein it is important to ensure that the closest to the sensor 46 permanent magnet 45a of the first control element 2a opposite polarity to the nearest permanent magnet 45b
  • a distinction between the two actuating elements 2a, 2b is possible due to the output signal of the sensor 46.
  • This arrangement produces four different signals for the four Anfahrbaren positions of the actuator, so that a clear assignment of the signal to the position of the actuator is possible.
  • the described actuator has a low power consumption as well as a high service life due to the low mechanical load of the magnet.
  • a possible release without too large to be applied actuating forces is also ensured as a sufficient tightening force by the permanent magnetic circuit before reaching the holding end position.
  • a holding force and a bearing feedback even with two actuators in a housing is ensured with only one sensor and prevents unwanted loosening. Furthermore, there is good electromagnetic compatibility.
