Definitions

  • the present invention relates to an actuating device with a housing and at least one electromagnetic linear actuator, which comprises an armature unit which can be moved relative to the housing and comprises a permanent magnet arrangement and a tappet coupled thereto, and a coil arrangement which is fixed to the housing and has at least one coil winding and extends around the permanent magnet arrangement, wherein the permanent magnet arrangement has an axially magnetized disc magnet and two flux guide pieces arranged on the end faces of the disc magnet.
  • Adjusting devices of the type mentioned above are known in various configurations. Reference is made, for example, to US 2014/0028420 A1 , but especially on the WO 2018/149694 A1 and the WO 2019/007675 A1 . Such adjusting devices are used, among other things, in the field of motor vehicle technology.
  • the DE 10 2011 009 327 A1 discloses an adjusting device according to the preamble of claim 1. It is based on the fact that the interior of a guide cylinder - forming a magnetic shunt - in which the permanent magnet arrangement of the anchor unit of the electromagnetic linear actuator can be moved, is enlarged in a length range such that for the Magnetic flux is formed a shunt air gap.
  • An embodiment is also disclosed in which one (oval) coil arrangement has two coils next to one another arranged armature units surrounds, the respective permanent magnet arrangement is movable in a corresponding guide cylinder.
  • Switching devices of the type specified which not only meet the usual, widely existing requirements to a large extent, but are also characterized by a comparatively high switching dynamics; because the fluid compensation channels incorporated in the permanent magnet arrangement allow a compensation movement of the fluid located in the space accommodating the permanent magnet arrangement in the opposite direction to the movement of the armature unit with comparatively little friction and therefore only a small damping effect, which is why comparatively short switching times can also be achieved with relatively compact coil arrangements.
  • the search for even better adjusting devices of the type specified at the outset that are even more attractive in practice--particularly in terms of manufacturing costs--continues unabated.
  • the disc magnet has a circular-cylindrical outer surface and the flux guide pieces are designed as round flux guide discs, and the coil arrangement also has at least part of its axial extent, namely at least in the area of its axial overlap the permanent magnet arrangement has a non-circular cross-section such that its inner surface has a gap with a first clear radial dimension on at least two first circumferential sections to the outer surface of the permanent magnet arrangement and on at least two bulged second circumferential sections, which are each assigned to a bulge of the coil winding, to the outer surface of the permanent magnet arrangement maintains a second radial clearance which is larger than the first radial clearance, the maximum value of the second radial clearance being substantially greater than the first radial clearance; In the region of the at least two second peripheral sections, there is a compensation channel with
  • the maximum value of the second clear radial dimension is at least three times the value of the first clear radial dimension.
  • the maximum value of the second clear radial dimension is even at least 5 times the value of the first clear radial dimension.
  • An adjusting device according to the invention which, in the implementation of the present invention, has a compensating channel for the fluid in the space accommodating the permanent magnet arrangement in the area of the at least one second circumferential section between the permanent magnet arrangement and the coil arrangement, can be produced at significantly lower costs than the functionally similar adjusting devices after WO 2018/149694 A1 and the WO 2019/007675 A1 .
  • the manufacture of the permanent magnet arrangement which has compensating channels on its surface—is comparatively complex, not only because the disc magnet and the two flux guide pieces on the respective scope corresponding recesses are to be introduced, but also because of the effort associated with the assembly of the permanent magnet arrangement with the mutually aligned alignment of the relevant recesses to one another. All this effort is superfluous in the case of the present invention, and without any significant additional effort for the production of the (at least internally) non-round coil arrangement; because the additional costs for the winding wire, which may be slightly longer than in the prior art due to the at least one bulge, are hardly significant.
  • winding wire can even be saved in the implementation of the present invention; because as a result of their outstanding efficiency, actuating devices according to the present invention often manage with a weaker dimensioned coil arrangement than actuating devices according to the prior art with similar performance data.
  • highly efficient adjusting devices can even be achieved with comparatively simple coils wound in only one winding direction, which—compared to the prior art presented—also has a cost-reducing effect and also enables very compact designs.
  • the advantages of the present invention come into play particularly in those applications in which there is not only air (or a gas) reliably in the space accommodating the permanent magnet arrangement, for example because oil or another liquid (carried over the tappet) has penetrated cannot be ruled out or even intended. This is because when the present invention is used, it is even possible to achieve compensating channels with a larger total cross-section than in the prior art without adverse effects on the magnetic situation.
  • first and three second peripheral sections there are at least three first and three second peripheral sections.
  • the second peripheral sections are preferably distributed uniformly over the inner circumference of the coil arrangement. In the sense already mentioned above, this supports a particularly uniform distribution of the magnetic flux within the linear actuator system and thus the performance.
  • the coil arrangement has a winding carrier (preferably made of plastic) with a sleeve section and two end-side support disks.
  • the sleeve section specifies - in the relevant area (see above) - the non-round inner contour of the coil arrangement or the non-round geometry of the coil winding. It is exclusively convexly curved, at least in the relevant area with locally different radii of curvature, possibly up to partially flat
  • the sleeve section is stepped in such a way that a partial area—which is offset axially with respect to the permanent magnet arrangement and does not overlap axially with it—overlaps the permanent magnet arrangement radially in a ring shape.
  • the sleeve section can definitely have a round cross-section on the inside.
  • the sleeve section also has a non-circular outer surface there, which can be achieved by having different wall thicknesses over the circumference.
  • the sleeve section of the winding carrier - in the at least one second peripheral section of the coil arrangement - has locally flat surface sections (see above), it can be advantageous if, analogously, at least the adjacent Support disc is limited on its outer circumference in a straight line on at least two sections.
  • the coil arrangement is accommodated in a cage.
  • the cage - which acts as a flux concentrator - consists of a magnetically highly permeable material (e.g. soft iron). It preferably comprises an end plate that covers the coil arrangement at the front and a casing structure that at least partially surrounds the coil arrangement on its outer circumference. It is particularly favorable, both with regard to a good magnetic flux and with regard to the production costs, if the end plate and the jacket structure are connected to one another in one piece and are produced by bending from a sheet metal blank.
  • the jacket structure has at least one flat surface section; for this may be connected to the faceplate (at a straight edge thereof) along a flexure of a length which accounts for an appreciable proportion (at least 10%, preferably at least 15%) of the perimeter of the shell structure.
  • the magnetic flow within the cage benefits from this.
  • Another advantageous embodiment is characterized in that a core which is coupled to the cage in a magnetic flux-conducting manner protrudes into the coil arrangement and also acts as a flux concentrator and for this purpose consists of a magnetically highly permeable material (eg soft iron).
  • the outer contour of the core is ideally adapted to the inner contour of the coil arrangement, namely a winding support that may be provided.
  • the core (which is designed approximately in the shape of a mushroom) preferably has a shoulder that corresponds to the step of the winding carrier.
  • the actuating device in a preferred development of the invention, has two electromagnetic linear actuators, a common cage structure with a continuous end plate covering both coil arrangements at the front is advantageously provided for these.
  • the statics in particular benefit from such a continuous common end plate, which means that a housing structure is less stressed and therefore has to be designed with less thick walls than in the case of two separate cages. It is also advantageous for the statics, regardless of the number of linear actuators, if the housing structure surrounding the coil arrangement of the at least one linear actuator is injection molded onto the cage (or cages), so that a composite structure is created in which both parts stiffen each other.
  • the two flux guide disks have different axial dimensions, specifically such that the flux guide disk located on the end face of the permanent magnet arrangement facing away from the ram is less thick than the other flux guide disk.
  • the disc magnet is designed as a ring disc magnet and at least one of the flux guide discs is designed as a flux guide ring disc, with the armature unit comprising a shaft that is coupled to the plunger and extends into the relevant flux guide ring disc and the ring disc magnet.
  • the shaft is preferably made of stainless steel or a material with a comparably low magnetic permeability.
  • the shank can be in one piece with the ram and merge into it.
  • the ram consists of a material with a higher degree of hardness than high-grade steel, for example high-strength steel.
  • the ram can be completely or partially provided with a suitable hard coating (e.g.
  • the shank and the ram are not areas of a one-piece component, the coupling of the shank to the ram can be implemented in particular in the form of a rigid connection.
  • a connection by means of laser welding or friction welding is particularly suitable.
  • the housing comprises an end piece designed as a mounting and guide block, with the anchor unit being movably guided in the mounting and guide block exclusively, namely via the plunger. So are lowest possible To realize friction losses, which in turn is favorable for a high material dynamics.
  • the illustrated first exemplary embodiment of an actuating device comprises a housing 1 and two electromagnetic linear actuators 2.
  • Each of the two linear actuators 2 comprises a coil arrangement 4 fixed to the housing and accommodated in a cage 3 acting as a flux concentrator, with a coil winding 6 accommodated on a winding support 5 and a coil winding 6 between two end positions - Anchor unit 7 that can be moved along the axis X relative to the housing 1.
  • This in turn comprises a plunger 8 and a permanent magnet arrangement 9 coupled to it, with an axially magnetized disc magnet 10 and two flux-conducting pieces 11 and 12 arranged on both sides on the face side of this.
  • the permanent magnet arrangement 9 is firmly connected to the plunger 8 (made of high-strength steel).
  • a shaft 13 (made of stainless steel) is welded to the plunger 8 and the permanent magnet arrangement 9 is accommodated on this shaft.
  • the disc magnet 10 is designed as a ring disc magnet 14 and the two flux guide pieces 11, 12 are designed as flux guide ring discs 15.

These each form a guide bore 21 for the plunger 8 of the associated linear actuator 2, the displaceably guided mounting of the respective anchor unit 7 being realized solely by guiding the respective plunger 8 in the associated guide bore 21 of the mounting and guide block 16.
  • the upper housing part 19 is molded onto the assembly consisting of the two coil arrangements 4 and the associated cages 3 , with a connection structure—not shown—which serves to contact the coil windings 6 forming an integral part of the upper housing part 19 .
  • the two cages 3 are part of a common cage structure 22 in that they have a common end plate 23 from which the respective jacket structure (see below) extends, at least partially surrounding the relevant coil arrangement 4 on its outer circumference.
  • the winding carrier 5 (made of plastic) has a sleeve section 24 and two support disks 25 at the ends.
