Definitions
- the present invention relates to an electromagnetic actuator with a coil arrangement with at least one coil core and a coil arranged circumferentially around the coil core, a housing with a magnetic material and with a movable magnetic armature body as a movable actuator element, which can be moved by a magnetic field generated by the coil arrangement, wherein the armature body is mounted on one side by means of a bearing in relation to the housing and can be moved from a first position to a second position about a bearing axis of rotation,
- Such electromagnetic actuators are known, for example, in the form of electromagnetic switching or valve devices, such as in the form of an electromagnetic relay or solenoid valve.
- Solenoid valves for example in the form of tilting armature valves, are used, for example, as control valves for regulating the pressure of air, for example in a vehicle, for example in a commercial vehicle or bus for passenger transport.
- a brake system for a vehicle with an electronic service brake system includes at least one control valve for pressure regulation.
- An electromagnetic actuator of the type mentioned above is known, for example, from DE 10 2016 105 532 A1 in the form of a tilting armature valve.
- the electromagnetic actuator has a coil arrangement and a movable magnetic armature body.
- the present invention is based on the object of specifying an electromagnetic actuator of the type mentioned at the outset, which enables better durability and greater efficiency.
- the invention relates to an electromagnetic actuator of the type mentioned in the opening paragraph according to the appended patent claims.
- Advantageous training and developments of the invention are specified in the subclaims and the following description.
- one aspect of the present invention relates to an electromagnetic actuator with a coil arrangement with at least one coil core and a coil arranged circumferentially around the coil core, a housing with a magnetic material and a rotationally symmetrical receiving space in which the coil arrangement is at least partially accommodated, and a movable magnet Armature body as a movable actuator element which can be moved by a magnetic field generated by the coil arrangement.
- the armature body is mounted on one side in relation to the housing by means of a bearing and can be moved from a first position into a second position about a bearing axis of rotation.
- the anchor body is disk-like and has a symmetrical shape with respect to an axis of symmetry lying in the plane of the disk, transverse to the axis of rotation of the bearing.
- the anchor body has a first greatest extent between opposite ends of the anchor body in the direction of the axis of symmetry and a second greatest extent between opposite ends of the anchor body in the direction of the bearing axis of rotation that is shorter than the first greatest extent.
- the electromagnetic actuator according to the invention enables the armature body to be moved safely and smoothly in the electromagnetic actuator, because the configuration of the armature body allows a greater tolerance of a position of the armature body in the housing.
- the electromagnetic actuator such as a solenoid valve for commercial vehicle applications, are made more robust and reliable with respect to the wear of the armature bearing.
- a transverse force of the magnetic field acting through the air gap can be reduced in an undesired direction and the magnetic field can be strengthened in the desired functional direction.
- the electromagnetic actuator according to the invention enables greater robustness with regard to manufacturing tolerances, without negative influences on the magnetic force and manufacturing costs.
- the axis of symmetry is arranged perpendicular to the axis of rotation of the bearing. This allows an even bearing force distribution of the anchor body in relation to the bearing axis of rotation. This allows the load to be applied to the bearing more evenly, thereby improving the durability of the electromagnetic actuator.
- the first greatest extent is a first diameter and the second greatest extent is a second diameter of the armature body.
- This shape enables an anchor body that is configured in a defined manner and is comparatively simple to produce, for improved positioning and reduction of transverse forces under tolerance conditions.
- the first largest extent is a largest diameter and the second largest extent is a shortest diameter of the armature body.
- the armature body has a convex, in particular oval, outer contour in the plane of the disc.
- Such an outer contour allows that even with an inclined position of the anchor body transverse to the bearing axis of rotation of the air gap between the housing and a outside on the circumference of the anchor body is sufficient.
- the magnetic flux can be directed more strongly in a preferred direction, so that it is reinforced at the longest lever arm and the magnetic force acting on the armature body is increased with a reduction in transverse forces.
- the armature body has two first opposite areas in the direction of the axis of symmetry, each with a round outer contour, and two second opposite areas in the direction of the bearing axis of rotation, each with an outer contour that is flattened compared to the first areas. This also enables improved positioning of the anchor body and a reduction in shear forces under tolerance conditions.
- the two first mutually opposite areas each have a circular outer contour.
- the two first opposing areas thus allow a largely constant air gap between the armature body and the housing near the bearing or the opposite end of the armature body.
- the respective flattened outer contour is barrel-shaped.
- Barrel-shaped means in particular that the contour is flattened compared to an arc of a circle and can in particular have different radii, with a middle part of the flattened outer contour having a larger radius than end parts of the flattened outer contour adjoining the middle part.
- the end parts of the flattened outer contour connect the flattened outer contour, for example, to a respective circular outer contour.
- the receiving space of the housing is cylindrical. Together with the anchor body, this enables good positioning under tolerance conditions and simplified manufacture.
- an air gap in the direction of the axis of symmetry between the anchor body at a position of the first greatest extension and a closest part of the housing is smaller than an air gap in Direction of the bearing axis of rotation between the anchor body at a position of the second greatest extent and an opposite part of the housing closest to it.
- the magnetic flux is positively deflected by the different widths of the air gap, so that the magnetic flux strengthens on the longest lever arm and the magnetic force on the armature body increases.
- the coil core has a rotationally symmetrical area with an axis of symmetry, in which the coil core is surrounded circumferentially by the coil, the bearing being arranged radially offset to the axis of symmetry of the coil core and the armature body extending radially over the coil core.
- the electromagnetic actuator is designed as an electromagnetic switching or valve device with the armature body as a switching or valve element, in particular as an electromechanical relay or solenoid valve.
- the electromagnetic actuator is designed as a toggle armature valve. According to one embodiment of the electromagnetic actuator, the electromagnetic actuator is designed as a solenoid valve for a pressure control module of a vehicle.

- 1 is intended to show an exemplary illustrate the practical use of an electromagnetic actuator using a tilting armature valve.
- FIG. 2 shows an exemplary anchor body 115, which is known from DE 10 2016 105 532 A1.
- the design of the anchor body 115 according to the invention can be illustrated more clearly with reference to FIG. 2 .
- a configuration of an armature body 115 according to the invention is shown in more detail in FIGS.
- the tilting armature valve 100 can be an exemplary embodiment of a tilting armature valve 100 shown in DE 10 2016 105 532 A1.
- this can be a solenoid valve provided with reference number 100 in FIG. 1 there.
- other exemplary embodiments are also conceivable, for example in connection with solenoid valves as described in the other publications mentioned above.
- Related configurations of a solenoid valve described in DE 10 2016 105 532 A1 and its components as well as their use are also part of the disclosure of the present invention by reference.
- the tilting armature valve 100 has a coil element 110, an armature body (or armature for short) 115, a spring 120, a sealing element 125 and a cover shell 130.
- the coil element 110 which has a rotationally symmetrical design with its main components coil, coil core and coil former, comprises at least one cylindrical coil core 135, which has an axis of symmetry 137, a circumferentially around the coil core 135 arranged bobbin 128, and a circumferentially arranged around the bobbin 128 coil 140 with a package of coil windings (not shown explicitly).

- the anchor body 115 is moveable between a first position 147 and a second position 149 .
- the armature body 115 is designed to be moved from the first position 147 into a second (tightened) position 149 when the coil 140 is activated.
- the armature body 115 can be held in the second position 149 .
- the sealing element 125 is arranged on the side of the armature 115 facing away from the coil element 110 .
- a valve seat 150 with an outlet 155 and an inlet 157 for a fluid 158 is formed in the cover shell 130 .
- the outlet 155 can be closed in a fluid-tight manner by means of the sealing element 125 when the anchor body 115 is arranged in the first position 147 .
- the sealing element 125 can also act as a damping element in order to prevent the armature 115 from striking the valve seat 150 .
- the sealing element 125 can be attached to the anchor body 115 or a carrier element by vulcanization. It is also conceivable that an angle is generated when the armature 115 or sealing element 125 hits the valve seat 150 by means of an inclined nozzle or an obliquely shaped sealing element 125 or a curved armature body 115 .
- Such a nozzle which is not explicitly shown in FIG. 1A, does not necessarily have to be integrated into the tilting armature valve 100, but can also be provided by external housing parts.
- valve seat 150 is arranged in the coil element 110, although this is not shown explicitly in FIG. 1A for reasons of clarity. In this case, an actuator would then be advantageous that mediates a release of the output through the anchor body 115 .
- armature body 115 has at least one at least partially round elevation 160 in a bearing section 162, elevation 160 engaging in a recess 165 or opening which, for example, is in a section of housing 170 or coil body 128 of the tilting armature valve opposite elevation 160 100 is arranged.
- the anchor body 115 in the recess when moving from the first position 147 to the second position 149 slide through the coil 140 after a current flow is switched on and is at the same time held in a fixed position in the housing 170 or in relation to the cover shell 130 .
- the recess is trapezoidal in shape so that the lowest possible friction is caused when the elevation slides over the surface of the recess 165 .
- the recess 165 can be made of plastic material, for example.
- the spring 120 is designed as a leaf spring and is arranged in the bearing section on a side of the armature 115 opposite the coil 140 .
- the spring 120 serves to press the bearing ball(s) pressed into the (e.g. trapezoidal) mating shell or recess 165 in the housing 170 of the coil element 110 without play, for example in the armature body 115.
- the armature body 115 can be fixed by the spring 120 so that the armature body 115 is held by the spring 120 in a predetermined position.
- the armature body 115 can also be hung on the coil element 110 .
- the spring 120 which is configured as a leaf spring, for example, could then be omitted.
- FIG. 1B shows a cross-sectional view through a toggle armature valve 100 in which the armature body 115 is in the second position 149.
- a current is switched on through the coil 140 and the armature body 115 is attracted, so that a magnetic field represented by the field lines 180 builds up.
- the armature body 115 can fall back into the first position 147, for example due to gravity or a spring force of a restoring spring 195 shown.
- Fig. 2 shows a perspective view of an exemplary prior art

- the anchor body 115 is designed here as a plate anchor.
- the armature body 115 has two pressed-in balls as elevations 160, 160a, which are arranged in a direction that forms a bearing axis of rotation A of the armature body 115 during rotation after the current through the coil 140 is switched on. This means that the elevations 160 and 160a are arranged on or along the axis of rotation A of the bearing.
- the elevations 160, 160a form part of a bearing arrangement in order to arrange the armature body 115 on an end face of the coil element 110.
- a spring fastening section 196 is formed centrally on the anchor body 115 , which interacts with the return spring 195 and prevents the return spring 195 from slipping off the anchor body 115 .
- the armature body 115 can be prestressed into the first position by means of the return spring 195 via the spring attachment section 196 in order to close the valve when the coil 140 is not energized.
- Fig. 3 shows a schematic cross-sectional view of an armature body 115 in a housing 170 along the disk plane of the armature body according to an embodiment of an electromagnetic actuator 105 according to the invention.
- the armature body 115 in Fig. 3 is in a rotationally symmetrical, in particular cylindrical, receiving space 171 of the likewise preferably cylindrical housing 170 arranged such that a circumferential air gap is formed between a circumference of the armature body 115 and an inner side 172 of the housing 170 .
- the anchor body 115 is disk-like or plate-like and has a symmetrical (here in particular axisymmetric) shape with respect to an axis of symmetry S lying in the plane of the disk.
- Disk-like or plate-like means in particular that the anchor body 115 has a thickness (in the direction perpendicular to the plane of the disk) that is less than an extent in the plane of the disk of the anchor body 115.
- the anchor body 115 is, as described by way of example with reference to FIG. cantilevered in relation to the housing 170 by means of a bearing 145 and movable along a bearing axis of rotation A between the first position 147 and the second position 149 .
- the bearing 145 is arranged, for example, near one end, in particular a first end 116 of the anchor body 115 .
- the bearing axis of rotation A is aligned transversely, in particular perpendicularly, to the axis of symmetry S and, like the axis of symmetry S, parallel to the disk plane.
- the bearing is exemplified by two bearing sections 161 and 161 arranged and spaced apart along the bearing axis of rotation A 161a (for example in the form of indentations in the armature body, which are indicated in FIG. 3), which allow the armature body 115 to rotate about the axis of rotation A of the bearing.
- the bearing sections 161 and 161a can be designed according to various aspects, for example as depressions or as elevations, as shown, for example, in FIG. 2 using the elevations 160, 160a. A variety of bearing types can be used.
- the bearing sections 161 and 161a are arranged in a radially outer region of the anchor body 115 in relation to a central point M, here an intersection point of a central axis in the normal direction of the anchor body 115 with the plane of the disk.
- a central point M here an intersection point of a central axis in the normal direction of the anchor body 115 with the plane of the disk.
- the bearing axis of rotation A is also arranged in a radially outer area of the anchor body 115 .
- the central point M is arranged approximately flush with the axis of symmetry 137 of the coil core 135 .
- the armature body 115 extends radially over the coil core 135 in relation to the axis of symmetry 137.
- the armature body 115 is mounted on one side in relation to the housing 170, so that a large part of the armature body 115 forms a lever arm on which a magnetic force generated by a magnetic field of the coil arrangement can act in order to move the armature body 115 into the second position 149.
- the lever arm extends essentially from the bearing axis of rotation A to a second end 117 of the anchor body 115 that is remote from the bearing axis of rotation A.
- the one-sided mounting of the anchor body means that the mounting is preferably at a front end or in an area between a front end and a central point of the anchor body is arranged.
- the anchor body 115 has a first largest extent D1 in the direction of the axis of symmetry S, here between the first end 116 and the second end 117.
- the largest extent D1 corresponds in particular to the largest diameter of the anchor body 115.
- the anchor body 115 has a second largest extent D2 between a third end 118 and a fourth end 119 in the direction of the axis of rotation A of the bearing.
- the second largest extension D2 is shorter than that first greatest extent D1.
- the second largest extension D2 corresponds in particular to the smallest diameter of the anchor body 115.
- the first largest extension D1 has a first, in particular the largest, diameter and the second largest extension D2 has a second, in particular the smallest, diameter.
- the anchor body 115 has a convex, in particular oval, outer contour.
- the anchor body 115 in this embodiment has a flat, rounded, convex outer contour in the plane of the pane.
- the anchor body 115 In the direction of the axis of symmetry S, the anchor body 115 has two first mutually opposite regions 115a with a respective round (e.g. circular) outer contour K.
- the first end 116 and the second end 117 of the anchor body 115 lie in the respective areas 115a.
- the armature body 115 In the direction of the bearing axis of rotation A, the armature body 115 has two second regions 115b lying opposite one another.
- the second mutually opposite regions 115b have an outer contour F that is flatter or flattened than the first regions 115a.
- the outer contour K which is circular here, has, for example, a radius r1, starting from the central axis of the anchor body 115, which is slightly smaller than an inner radius of the housing receiving space 171, so that an air gap 191 remains between the first regions 115a and the inside of the housing receiving space 171.
- the outer contour F which is barrel-shaped here, has a larger radius r2 or r3 than the radius r1.
- a design point P1 for the radius r2 lies between the central axis and the right second region 115b with reference to FIG. 3 .
- a design point P2 for the radius r3 lies between the central axis and the opposite second region 115b.
- a barrel-shaped contour includes in particular that there is at least one contour or partial contour that has a rounded or arched, in particular outwardly arched (convex) shape, in particular a shape that deviates from a circular arc shape.
- a rounded or arched, in particular outwardly arched (convex) shape in particular a shape that deviates from a circular arc shape.
- arched or rounded aspect in particular deviating from a circular arc shape, narrowing the disk shape, is important, without an exact barrel shape in the mathematical sense being important, but which can also have specific advantages with regard to positioning under tolerance conditions.
- This term should also include, for example, elliptical, egg-shaped or other long, rounded or curved contours.
- straight contours can be provided in contour areas that are located between rounded contour areas.
- FIG. 4 shows the armature body 115 in a deflected position, in particular in a position pivoted under tolerance conditions, for example in the second tightened position 149 of FIG. 1, for example under the influence of the magnetic force. 4 shows an exemplary position of the armature body 115, such as when a magnetic field is generated by the coil assembly.
- the anchor body 115 is positioned off-centre due to tolerances. For example, due to tolerances in the bearing 145, tolerances in the design of the armature body 115 and/or tolerances on the housing 170.
- a reduced, preferably minimal air gap 191 can be formed in the direction of the axis of symmetry S, even if the anchor body 115 pivots in the direction of the bearing axis of rotation and is eccentric in moved in the direction of a part of the housing 170, in Fig. 4 for example to a left part of the housing 170. Due to the still relatively small air gap on both sides of the armature body 115 in the direction of the axis of symmetry S, the magnetic flux is still directed positively in the working direction, especially in the direction of the longest lever arm.
- the armature body 115 is both offset radially with respect to the axis of symmetry 137 and rotated in the housing 170. This makes it clear that the armature body 115 can not only be displaced linearly by the magnetic field, but can also be rotated about the axis of symmetry 137 of the coil core 135 . This means that the bearing sections 161 and 161a are not only loaded along the bearing axis of rotation A, but also partially along the axis of symmetry S.
- the air gap between the armature and the housing can be reduced on both sides (in the direction of the axis of symmetry S), in particular depending on possible wear of the bearing and component tolerances.
- a tolerance-dependent axis of rotation (axis of symmetry) perpendicular to the axis of rotation of the bearing is defined.
- the anchor body can be turned around this axis to a maximum tolerance and the outer contour of the anchor can be generated by means of a defined minimum air gap. This results in a round disc shape with lateral, barrel-shaped flat areas based on the original diameter. Greater robustness with regard to wear and manufacturing tolerances is thus achieved, largely without negative effects on the magnetic force and manufacturing costs.
