[0003] DESCRIPTION

[0004] Tilting anchor device for a valve device for a vehicle and valve device

[0005] The present invention relates to a tilting anchor device for a valve arrangement for a vehicle and to a valve device for a vehicle with such a tilting anchor device.

[0006] In tilting armature devices or tilting armature magnet systems, sometimes also referred to as hinged armature magnet systems, an armature can be moved relative to the valve opening to control the cross-sectional area of ​​a fluid-mechanical valve. This allows the armature to at least partially open and at least partially close the valve opening, either directly or indirectly, depending on the desired degree of opening. For this purpose, the armature in a tilting armature device is rotated, or tilted, around an axis. This rotational or tilting movement in at least one direction is initiated by an electromagnet. To implement the rotational movement, the armature can be rotatably mounted in a bearing. For example, a tilting armature device has a bearing block in which the armature's axis of rotation is supported.In practice, such bearings are predominantly associated with play or other tolerance-related inaccuracies in fit, which can negatively affect switching or movement accuracy. Especially with a high number of switching cycles, the resulting wear must be taken into account, potentially requiring costly countermeasures or accepting a shorter service life.

[0007] The object of the present invention is to provide a valve device with a simple, essentially wear-free bearing for a tilting anchor. 2024PF00136

[0008] 2

[0009] The problem is solved by the subject matter of the independent claims.

[0010] Advantageous further training is the subject of the sub-claims.

[0011] According to the invention, a tilting armature device for a valve device for a vehicle comprises an armature, which is formed at least partially from a magnetizable material, a bearing surface for the armature, and at least one bearing element that rotatably supports the armature about an axis of rotation. The at least one bearing element is configured to deform elastically at least partially, so that the armature is essentially reversibly movable about the axis of rotation between a first position in which the armature is spaced at least partially away from the bearing surface, and a second position in which the area of ​​the armature provided for bearing on the bearing surface is at least larger than in the first position.

[0012] The armature is thus designed to be moved between a first and a second position by a magnetic force that can be applied by a magnet, in particular an electromagnet. For example, the first position corresponds to a state in which no magnetic force, or at least no magnetic force sufficient to move the armature, acts on it. If the magnet increases the magnetic force acting on the armature, it can thereby be moved into the second position. In the case of an electromagnet, this increase in the magnetic force acting on the armature can be achieved by switching on or increasing a current, or in the case of a permanent magnet, by moving it to a position closer to the armature. The magnet can be part of the armature assembly or part of a valve assembly described later.

[0013] The movement of the anchor from the first position to the second position corresponds to a movement of the anchor towards the bearing surface. In the context of the anchor as a tilting anchor, a section of the anchor facing away from the axis of rotation moves towards the bearing surface when the anchor moves from the first position to the second position. The axis of rotation therefore runs essentially parallel to the bearing surface for the anchor. The term "essentially parallel" refers to a fundamental directional characteristic to distinguish a perpendicular 2024PF00136

[0014] 3

[0015] Direction. Accordingly, the axis of rotation can also form a predetermined or tolerance-related angle to the support surface, whereby the basic principle of movement in the direction of the support surface remains applicable even at this angle. Preferably, however, the axis of rotation runs parallel to the support surface, except for tolerance-related deviations.

[0016] In the second position, the contact surface can serve as a stop for the armature, preventing further movement. However, the second position can also be defined by a balance between the magnetic force acting on the armature and the restoring force resulting from elastic deformation.

[0017] Due to the at least partial elastic deformability of the bearing element, the movement of the armature from the first position to the second position is caused at least predominantly by elastic deformation resulting from the action of the magnet on the armature. Accordingly, the bearing element is configured such that the deformation required to move the armature from the first to the second position lies within the elastic deformation range of the bearing element. Consequently, the movement of the armature from the first to the second position is essentially reversible. The term "essentially reversible" in this context means that the movement can be repeated bilaterally, i.e., from the first to the second position and from the second to the first position, and can occur under elastic deformation. If necessary,Repeated bilateral movement can cause metallurgical effects that are irreversible but have no discernible influence on the described operating principle of the reversible movement. In particular, elastic deformation upon the loss or reduction of the magnetic force can automatically move the bearing element back from the second position or an intermediate position to the first position.

[0018] The bearing element can be integrally formed with the anchor or connected to it. The bearing element is also connected to, or integrally formed with, the bearing surface or another fastening section of the tilting anchor device or the valve device described later. The connection between the anchor and the bearing surface or the 2024PF00136

[0019] 4

[0020] The fastening section over the bearing element, which allows elastic deformation, is comparable to a bending beam, with the axis of rotation located inside the bending beam.

[0021] In one embodiment, at least one bearing element is connected to the support surface without play in at least one direction via at least one first fixing section.

[0022] The backlash-free connection with the bearing surface, which can be achieved by integrally integrating at least one first fixing section with the bearing surface or by using a backlash-free connection method, allows backlash-free relative movement of the bearing element with respect to the bearing surface in at least one direction. This backlash-free movement refers in particular to at least the direction that would otherwise result in relative movement in the connection area when the anchor moves around its axis of rotation. However, the backlash-free connection is not limited to this direction and can also be designed for other potential directions of movement.

[0023] The principle of a backlash-free connection can also be applied to a connection with a different mounting section. This alternative mounting section is used as an alternative to the contact surface and can, for example, be a housing section located near the contact surface to still allow sufficient movement of the anchor towards the receiving surface.

[0024] In one embodiment, at least one bearing element is connected to the anchor in at least one direction without play via at least a second fixing section.

[0025] Here too, a backlash-free connection can be achieved through the integral design of at least one second fixing section with the bearing surface, or through a backlash-free connection method. Analogous to the explanations regarding the at least one 2024PF00136

[0026] The first fixing section is also here at least one direction in which play is prevented, in particular a direction of movement of the anchor from the first position to the second position.

[0027] With regard to a backlash-free connection of at least one first fixing section and / or at least one second fixing section, rigid connection sections can thus be created by the bearing element.

[0028] In one embodiment, the backlash-free connection of at least one first fixing section and / or at least one second fixing section is designed as a material-locking, form-locking and / or force-locking connection.

[0029] A material-bonded connection enables a permanent, secure bond, while form-fitting and / or force-fitting connections allow for easy disassembly of the connection.

[0030] In one embodiment, the backlash-free connection of at least one first fixing section and / or at least one second fixing section is designed as a spot weld.

[0031] Spot welding can be easily implemented using one or more spot weld points. Alternatively, other types of material-bonded connections, such as other welding processes, soldering, and / or bonding, can also be used as alternatives or supplements.

[0032] In one embodiment, the backlash-free connection of the at least one first fixing section and / or the at least one second fixing section is formed via at least one detent section, which is formed by the bearing surface or the anchor and / or the bearing element, or which the bearing surface or the 2024PF00136

[0033] 6

[0034] has an anchor and / or the bearing element to lock the bearing surface or the anchor to the bearing element.

[0035] The at least one locking section can, for example, be designed as a clip. In one embodiment, the anchor can have punched locking sections as a clip, into which corresponding sections of the at least one second fixing section can be clipped.

[0036] According to the backlash-free connection, at least one locking section is configured to hold the locking section in at least one direction in a form-fit and / or force-fit manner.

[0037] In one embodiment, the backlash-free connection of the at least one first fixing section and / or the at least one second fixing section is formed via a fastening element, in particular a clamping screw.

[0038] A clamping screw allows for a positive-locking, backlash-free connection. In this context, the fastening element refers specifically to a component separate from the anchor, the bearing element, and the contact surface, which is used to create a backlash-free connection in at least one direction. As an alternative or supplement to a screw, a rivet, nail, or similar fastener can also be used.

[0039] In one embodiment, the at least one bearing element has a deformation section formed between the at least one first fixing section and the at least one second fixing section, wherein at least the deformation section is designed as a spring-elastic element.

[0040] Accordingly, the entire bearing element does not need to be elastically deformable; elastic deformability can also be present only in the deformation section. This allows the load on a respective backlash-free connection 2024PF00136

[0041] 7 can be reduced. Alternatively, at least the first fixing section and / or the second fixing section can also be elastically deformable at least section by section or be formed by the spring-elastic element, whereby the elastic deformation in the first fixing section and / or the second fixing section is then prevented at least section by the backlash-free connection.

[0042] The deformation section can be designed as a spring-elastic element, for example, by selecting a suitable spring-elastic material and / or dimensioning the deformation section accordingly. The deformation section can also be designed as a spring hinge.

[0043] In one embodiment, at least one bearing element or at least the previously described deformation section is designed as a leaf spring, in particular made of copper or a copper alloy.

[0044] Leaf springs, especially those made of copper or copper alloys, particularly copper-berilium alloys, are readily available and provide a simple way to implement the bearing element, which can be used as a bending beam.

[0045] In particular, the leaf spring can be easily deformed, for example by folding or bending it to form a bearing element which has a first fixing section and a second fixing section, wherein the elastic deformation section forms a height offset between the first fixing section and the second fixing section.

[0046] In one embodiment, at least one bearing element or at least the previously described deformation section is designed as a wire spring, in particular as a wire spring clip. 2024PF00136

[0047] 8

[0048] A wire spring is readily available as an alternative to a leaf spring, and a corresponding bearing element can be easily implemented using this design. The basic body of the wire spring bracket, as a configuration of the wire spring, essentially has a U- or V-shaped form, with the legs of the wire spring bracket serving, at least partially, as secondary fixing sections, and the area between the legs being used as the primary fixing section. The wire spring bracket preferably has two elastic deformation sections, each formed between the primary fixing section and one of the two secondary fixing sections. These deformation sections also create a height difference between the primary fixing section and the secondary fixing sections. Compared to a simple wire spring, the wire spring bracket allows for increased stability of the bearing element and / or a reduction in the wire diameter.

[0049] In one embodiment, the tilting anchor device has at least one anti-rotation element which is configured, either on its own or with at least one further anti-rotation element for the bearing element, to form an anti-rotation device in a plane parallel to the bearing surface about an axis perpendicular to the axis of rotation of the anchor.

[0050] While the backlash-free connection of the bearing element is primarily directed in one direction corresponding to the movement of the anchor around its axis of rotation, other external forces, such as vibrations or shocks, can also have directional components that deviate from the movement of the anchor around its axis of rotation. To prevent, in particular, a resulting rotation of the bearing element around an axis different from the axis of rotation of the anchor, the bearing element can be secured against such movement by at least one anti-rotation device. This anti-rotation device can be designed, in particular, as a positive-locking and / or friction-locking connection. 2024PF00136

[0051] 9

[0052] In one embodiment, the anti-rotation device is formed from at least two anti-rotation elements that protrude from the bearing surface.

[0053] By incorporating anti-rotation elements into the bearing surface, at least one fixing section can be easily secured. Since the bearing surface is predominantly customized for each application, for example, cast and / or machined according to specifications, anti-rotation elements can be directly integrated and implemented without significant effort. Projections acting as anti-rotation elements can also be implemented using pins inserted into the bearing surface. In contrast, bearing elements such as leaf springs or wire springs are usually standard components whose dimensions and deformations can be easily adapted, while incorporating anti-rotation elements, although possible, is more complex.

[0054] Anti-rotation elements can be implemented by using two projecting anti-rotation elements that project at least far enough to prevent or restrict the movement of the bearing element in the direction intended for anti-rotation, with at least one outer surface. With regard to a leaf spring, the at least two anti-rotation elements can, for example, each be arranged on an outer surface of the leaf spring. With regard to a wire spring clip, the at least two anti-rotation elements are, in particular, each arranged on an inner outer surface of a respective leg or each on an outer outer surface of a respective leg.

[0055] More than two anti-rotation elements may also be provided, whereby, for example, the first fixing section of the wire spring clip is secured against twisting by means of a meandering wire winding around at least four anti-rotation elements.

[0056] In one embodiment, the contact surface is made of a non-magnetic material. 2024PF00136

[0057] 10

[0058] The contact surface therefore does not affect the configuration intended for moving the armature by a magnet through its own magnetic properties.

[0059] In one embodiment, the anchor is designed as an anchor disk, which in particular has an elliptical disk shape or at least an elliptical disk segment.

[0060] The elliptical disc shape refers to the opposing disc surfaces, with one of the disc surfaces at least partially in contact with the bearing surface. The disc surface can also consist of only a single elliptical disc segment. For example, the disc shape can deviate from a completely elliptical shape by means of a recess. The recess can be used to avoid or reduce an interference contour for the bearing element.

[0061] The elliptical disc shape can particularly help to concentrate the flow.

[0062] The elliptical shape can represent a possible flow concentration and “freedom” from the lateral mechanical “narrowings” and thus avoid any jamming due to further tolerances.

[0063] In another aspect, the present invention relates to a valve device for a vehicle. The valve device comprises a previously described tilting armature device, a valve opening which provides a smaller valve opening cross-section in the first position of the armature than in the second position of the armature, and an electromagnet configured to move the armature from the first position to the second position when energized.

[0064] The electromagnet can be configured such that the magnetic force acting on the armature only allows movement from the first to the second position at any given time. 2024PF00136

[0065] 11 can be caused. However, the electromagnet can also be configured in such a way that its polarity is reversible, so that a movement of the armature from the second to the first position can be supported.

[0066] For example, the electromagnet is arranged on the side of the support surface and, when energized, moves the armature towards the support surface by its attractive force, thereby increasingly opening a valve opening of a fluid channel on the side of the armature facing away from the electromagnet or the support surface, which was previously at least partially covered by the armature, until the second position is reached.

[0067] Alternatively to the above configuration, the contact surface can also form a valve opening for a fluid channel, with the electromagnet then being arranged on the side of the armature facing away from the contact surface. When energized, the electromagnet then exerts a force on the armature, which moves the armature towards the contact surface – in this case, a repulsive force. The first position of the armature in this case requires a larger valve opening cross-section than the second position.

[0068] The features described above for the tilting anchor device are equally applicable to the valve device. Likewise, features described for the tilting anchor device in the valve device description are transferable to the tilting anchor device, provided they have not already been described therein.

[0069] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings.

[0070] In detail, it shows

[0078] Fig. 7 shows a schematic top view of a section of a bearing element with an anti-rotation variant.

[0079] Fig. 1 shows a schematic top view of a tilting armature device 10 according to a first exemplary embodiment. In the exemplary embodiment, the tilting armature device 10 comprises a housing 1, a support surface 2, an armature 3, a bearing element 4, and an electromagnet 5. More precisely, the reference numeral 5 refers to the so-called pole core, which forms part of the magnetic iron circuit and thus enables flux guidance via the armature 3.

[0080] In alternative embodiments, however, the housing 1 and the electromagnet 5 can also be part of a valve device, i.e., not provided solely by the tilting device 10.

[0081] The valve opening is not shown, as the opening can occur directly via the armature 3 or indirectly (plumb). Therefore, only the area of ​​the electromagnetic actuator is shown. The housing 1, the bearing element 4, and the electromagnet 5 2024PF00136

[0082] Thirteen parts are flux-carrying and therefore magnetizable. The other parts are made of non-magnetizable material.

[0083] The contact surface 2 is designed here as a disc made of a non-magnetic material, which has an opening for receiving the electromagnet 5. The electromagnet 5 is located on the side of the contact surface 2 facing the armature 3 and does not protrude beyond the contact surface 2. In this embodiment, the disc forming the contact surface 2 is round and inserted into a round open cross-section of the housing 1. In alternative embodiments, shapes other than a round geometry may also be provided.

[0084] In the first embodiment, the bearing element 4 is a leaf spring comprising a first fixing section 4a, a second fixing section 4c, and a deformation section 4c arranged between the first fixing section 4a and the second fixing section 4c. The leaf spring thus extends from the first fixing section 4a, through the deformation section 4b, to the second fixing section 4c, with this extension defining a longitudinal direction of the leaf spring. The first fixing section 4a is connected to the bearing surface 2 by two spot welds 41, arranged one behind the other in the longitudinal direction, without play. The second fixing section 4c is also connected to the anchor 3 by two spot welds 41, arranged one behind the other in the longitudinal direction, without play.Accordingly, the anchor 3 moves in the direction of the bearing surface 2 via the elastic deformation section 4b, as will be described later.

[0085] In the present embodiment, the armature 3 is formed from an elliptical disk with a recess or a corresponding elliptical disk segment made of magnetic material. The recess ensures that the elastic deformation of the deformation section 4b is not obstructed by the armature 3.

[0086] Fig. 2 shows a schematic cross-sectional view along cross-sectional line AA of the tilting anchor device of Fig. 1. As can be seen in Fig. 2, the leaf spring is designated as 2024PF00136

[0087] 14 The bearing section 4 is deformed such that the deformation section 4b forms a height offset between the first fixing section 4a and the second fixing section 4c. The height offset is perpendicular to the bearing surface 2. Furthermore, the deformation section 4b creates a gap in the longitudinal direction of the bearing element 4 between the first fixing section 4a and the second fixing section 4c. The second fixing section 4c extends at an angle to the extension of the first fixing section 4a in a direction away from the bearing surface 2. In other words, the first fixing section 4a extends parallel to the bearing surface 2, followed by the deformation section 4b, which extends at an angle to the bearing surface 2, from which the second fixing section 4c extends in a direction also angled to the first fixing section 4a.This initially holds anchor 3 in a first position angled relative to the support surface.

[0088] When the electromagnet 5 is energized, the resulting attractive force on the armature 3 in the direction of the support surface causes a corresponding tilting movement of the armature 3. This tilting movement corresponds to a rotation of the armature 3 about an axis of rotation formed in the deformation section 4b, according to the elastic deformation of the bearing element 4 in the deformation section 4b. This allows the cross-sectional area of ​​the valve opening of a fluid channel (not shown) of a valve device to increase on the side facing away from the electromagnet 5, starting from the initial position of the armature 3, with increasing tilting movement. The support surface 2 acts as a stop for the armature 3 to limit its movement about the axis of rotation. The contact of the armature 3 against the support surface 2, resulting from the rotational or tilting movement of the armature 3 initiated by the electromagnet, then corresponds to a maximum valve opening cross-sectional area.If the electromagnet 5 is de-energized or the corresponding magnetic force acting on the armature 3 is reduced, the armature 3 moves back to its initial position or to an intermediate position in which the restoring force and any remaining, but reduced, magnetic force are in equilibrium, according to the restoring force caused by the previous elastic deformation. The movement of the armature 3 into a 2024PF00136.

[0089] 15

[0090] An intermediate position can also be set during a movement from the first position to the second position according to the magnetic force acting on the armature 3.

[0091] Fig. 3 shows a schematic top view of a tilting anchor device 10' according to a second exemplary embodiment. The second embodiment differs from the first embodiment essentially by a different design of the bearing element 4'. For independent components and functionalities, reference is made to the description of the first embodiment. For the sake of clarity, the first and second fixing sections are not explicitly shown again here, but can be understood analogously to the first embodiment or from the following description of the figures.

[0092] In the second embodiment, the bearing element 4' is designed as a wire spring clip having a substantially U-shaped form. The first fixing section 4a is formed between the respective legs, while each leg in turn has a second fixing section 4c and a deformation section 4c arranged between the first fixing section 4a and the respective second fixing section 4c. Due to the design of the bearing element 4' as a wire spring clip, the anchor 3' has a truncated elliptical disc shape in order not to impede the elastic deformation of the deformation sections 4c.

[0093] The first fixing section 4a is semicircular in shape to partially encircle a clamping screw 6. The clamping screw 6 is screwed into the bearing surface 2 to clamp the wire spring in the first fixing section 4a between the bearing surface 2 and the clamping screw head without play. To prevent rotation of the bearing element 4' and thus of the anchor 3 about an axis perpendicular to the bearing surface, two anti-rotation elements 7 are provided. These are each located on the inner outer sides of the legs at the starting point of the leg extension in a direction away from the deformation sections 4b. The fixing of the 2024PF00136

[0094] 16

[0095] The connection of the bearing element 4' to the armature 3' is made via solder joints not shown in the second fixing sections 4c.

[0096] Fig. 4 shows a schematic cross-sectional view according to the cross-sectional line AA of the tilting anchor device 10' of Fig. 3. Similar to the first embodiment, the first fixing section 4a extends parallel to the bearing surface 2, followed by the deformation sections 4b which extend at an angle to one of the bearing surfaces 2, from which the second fixing sections 4c extend further in a direction also angled to the first fixing section 4a.

[0097] The operating principle of the tilting anchor device 10' is analogous to the operating principle of the tilting anchor device 10 described for the first embodiment.

[0098] Fig. 5 shows a schematic cross-sectional view of a section of an anchor 3" with an exemplary detent section 31". The detent section 31" forms a clip with which, or into which, a leg of the wire spring clip can be detented or clipped as a bearing element 4'. The detent section 31" is stamped into the anchor 3" for this purpose.

[0099] Fig. 6 shows a schematic cross-sectional view of a section of an anchor 3'" with an exemplary locking section 31 '" according to a further embodiment. Here, the locking section 31 is formed from an edge projection of the anchor 3'", which extends parallel to the disk surface of the anchor 3'" and is deformed into a clip.

[0100] Fig. 7 shows a schematic top view of a section of a bearing element 4" with an anti-rotation device. The bearing element 4" differs from the bearing element 4' by the anti-rotation device formed in the area of ​​the first fixing section 4a. Here, the anti-rotation device is formed from four anti-rotation elements 7' around which the wire spring is wound in a meandering pattern. 2024PF00136
