Definitions
- the invention relates to a method for producing an electromagnetic actuator according to the preamble of patent claim 1.
- An electromagnetic actuator for actuating a gas exchange valve in an internal combustion engine is known from DE 1 96 31 909 A1.
- the known actuator comprises two electromagnets which are arranged at a distance from one another and an armature which is operatively connected to the gas exchange valve and which can be moved back and forth by magnetic force between the electromagnets against the force of a spring arrangement comprising two springs which act against one another.
- the actuator also has actuating means with which the rest position of the armature, ie. H. the position of the armature with de-energized electromagnets, is set to the geometric center between the two end positions of the armature. It proves to be disadvantageous here that the rest position can shift during operation, so that after a number of operating hours a readjustment of the rest position is necessary.
- the invention has for its object to provide a method according to the preamble of claim 1, by which an optimal and permanent adjustment of the bias of the springs is made possible for the operation of the actuator.
- the object is achieved by the features of patent claim 1.
- FIG. 1 shows a basic illustration of an electromagnetic actuator for actuating a gas exchange valve in an internal combustion engine
- Figure 3 shows the energy stored in a spring as a function of the number of compression cycles.
- a spring arrangement with a first spring 61 acting on the armature 1 in the opening direction via a first spring plate 60 and a second spring 62 acting in the closing direction on the armature 1 via a second spring plate 63 cause the armature 1 in the de-energized state of the
- Excitation coils 20, 30 is held in an equilibrium position between the electromagnets 2, 3. Furthermore, adjusting means 71, 72 are provided for setting the prestresses of the springs 61, 62.
- the actuating means 71, 72 can be designed, for example, as disks, which compress the springs 61, 62 and thus predefine the prestressing of the respective springs 61, 62. However, they can also be designed to be controllable and enable the pretension to be varied continuously.
- the closing magnet 3 is switched off and then the opening magnet 2 is energized.
- the first spring 61 acting in the opening direction accelerates the armature 1 beyond the rest position.
- the now energized opening magnet 2 also supplies the armature 1 with kinetic energy, so that it reaches the pole face of the opening magnet 2 despite any frictional losses and is held there at the lower end position or open position indicated by dashed lines in FIG. 1 until the opening magnet 2 is switched off.
- the opening magnet 2 is switched off and the closing magnet 3 is then switched on again.
- the armature 1 is thus moved by the second spring 62 to the closing magnet 3 and held there on the pole face in the closed position.
- the spring characteristic of the first spring 61 is designated F1 and the spring characteristic of the second spring 62 is designated F2.
- Different springs are used in the present exemplary embodiment; their spring characteristics thus differ from each other. However, the use of the same springs is also conceivable.
- the force of the first spring 61 drops from a holding value F1 1 to a final value F10, which at the armature position Im, i. H. with armature 1 resting on the opening magnet 2.
- the spring force 0 of the second spring 62 increases from an end value F20 acting in the upper end position of the armature 1 to a holding value F21 which is reached in the lower end position of the armature 1.
- the first spring 61 is installed in the part comprising the electromagnets 2, 3 and the armature 1 and the second spring 62 with the gas exchange valve 5 and the second Spring plate 63 is installed in the cylinder head of the internal combustion engine and that the springs in these sub-assemblies are compressed independently of one another in repetitive compression cycles by a certain compression value, the compression cycles being repeated until the setting process has ended.
- the compression value is chosen equal to the value by which the springs 61, 62 are compressed during the intended operation of the actuator.
- the determination of the energy A1 or A2 takes place in that the spring force F1 or F2 which results during the armature movement is measured in sections and is integrated in sections via the spring travel.
- the spring force F1 or F2 can be measured by means of a load cell or a dial gauge, but also with other pressure sensors, in particular with piezo crystals. If the difference between the energy A1 or A2 determined in the current compression cycle and the energy determined in a previous compression cycle for the same spring 61 or 62 is smaller than a predetermined value, this is a
- Compression cycle in the spring 61 or 62 stored energy differs.
