Description

Technical Field

[0001] The present invention relates to a support device that applies a preload gravity to position-fix and support an armature body of an electromagnetic switching device or valve device, and an electromagnetic switching device or valve device provided with such a support device.

[0002] Such electromagnetic switching devices or valve devices are known, for example, in the form of electromagnetic relays or electromagnetic valves. For example, a solenoid valve in the form of a tilting armature valve is used, for example, as a control valve for pressure regulation, for example, in a vehicle, for example, in a commercial vehicle or a bus for passenger transportation. For example, a braking system for a vehicle equipped with an electronic service braking system includes at least one control valve for pressure regulation.

[0003] The tilting armature valve is known, for example, from German Patent Application Publication No. 102016105532. The tilting armature valve has a coil member provided with a coil core, a coil arranged to surround the coil core in the radial direction, and an armature supported by a support at one end face of the armature body. In this case, the armature is movable from a first position to a second position, particularly by supplying current to the coil. Further, a valve seat provided with an outlet and an inlet for fluid are provided. In this case, the outlet can be fluid-tightly closed by a sealing member in the first position of the armature, and the outlet is open in the second position of the armature. In one embodiment, a spring is provided to press the armature against the coil member or housing of the tilting armature valve.

[0004] Furthermore, another configuration form of a solenoid valve, as described, for example, in German Patent Application Publication No. 102014115207, German Patent Application Publication No. 102018123997 or German Patent Invention No. 102014115206, is also known.

[0005] In electromagnetic switching or valve devices, such as solenoid valves of the configuration described above, conventional armature guides and armature supports are usually formed via shape couplings, spring-loaded supports, or fixed flexible supports. In the case of tilting armatures in relays, supports similar to simple hinges are often used, and these supports are fixed in position by plastic deformation during the installation process. In contrast, in the case of solenoid valves, "cantilevered" double-acting armatures are widely used. In electromechanical switching members with small working strokes, thin leaf springs are rigidly coupled and move within their elastic range during use. Tilting armatures in valve technology often have spring-loaded supports to ensure play-free and wear-independent operation.

[0006] In the case of a support section preloaded by a spring, in most cases, the support spring has an influence on the armature body and, consequently, on the switching or valve member. This influence is important to the function in a positive, neutral, or negative way, depending on manufacturing tolerances and installation. In particular, when used as an actuator in control circuits and adjustment circuits, high repeatability and consistent switching operation over mass production are essential. For economic reasons, typical coil springs are often used. However, this spring member has the disadvantage that the point of force application is not located at the center of the spring's central axis, but is always eccentric due to manufacturing. Because oriented installation of the spring is extremely time-consuming, different points of force application are created. Furthermore, spring centering is also necessary because, in most cases, the spring does not only move in the axial direction in a tilting armature. This centering makes installation difficult and increases the risk of failure due to installation errors.

[0007] Furthermore, precise spring design is impossible with current methods due to the superposition of translational and rotational motions of the tilting armature. Regarding mounting, when using directly acting springs, the mounting direction must also be considered, as support springs are generally located on the opposite side from the armature stroke return spring. Therefore, additional measures are needed to hold the spring members in their intended position until they are fully mounted.

[0008] The fundamental problem of the present invention is to provide a support device for fixing and supporting the armature body of an electromagnetic switching device or valve device by applying a preload force, which enables the introduction of force to a predetermined support position on the armature body with relatively little installation effort, and an electromagnetic switching device or valve device equipped with such a support device.

[0009] The present invention relates to a support device for positioning and supporting the armature body of an electromagnetic switching device or valve device as described in the appended independent claims, by applying a preloading force, and to an electromagnetic switching device or valve device equipped with such a support device. Advantageous configurations and improvements of the present invention are described in the dependent claims and the following description.

[0010] In particular, one aspect of the present invention relates to a support device for fixing and supporting the armature body of an electromagnetic switching device or valve device by applying a preload force, the support device comprising a support force generating member for generating a preload force to support the armature body, and a transmission member formed separately from the support force generating member, wherein the transmission member is pressed toward the armature body by the preload force generated in the mounting state of the support device to fix and support the armature body, the transmission member having a first side and a second side located on the opposite side, the first side facing the support force generating member, and the second side facing the armature body in the mounting state of the support device and in contact with the armature body at at least one force introduction point of the armature body such that the force introduction point is mechanically separated from the support force generating member, and the support device further comprises a guide device formed to at least partially surround the transmission member and to guide and position the transmission member at the force introduction point of the armature body.

[0011] Another aspect of the present invention relates to an electromagnetic switching device or valve device comprising an electromagnetic actuator, a movable armature body as a switching member or valve member cooperating with the electromagnetic actuator for operating the armature body, and a support device according to the present invention, wherein the armature body is fixedly positioned and supported within the switching device or valve device by the support device on one side, and is movable from a first position to a second position by the operation of the electromagnetic actuator.

[0012] In other words, the present invention makes it possible to set the force introduction to a predetermined support position on the armature body with relatively little installation effort, even when using different support force generating members, such as spring members of different configurations. This is made possible by using a transmission member according to the present invention that contacts at least one force introduction point on the armature body at the support position of the armature body, in which case the force introduction point on the armature body is mechanically separated from the support force generating member by the transmission member.

[0013] This type of support force generating means for a support position to which a preload, particularly a spring load, is applied, can be applied in virtually any electromagnetic tilting / flap armature solenoid valve device and switching device. By using a preloaded transmission member for disconnection, the force can be directed to a specific point on the armature body. At the same time, the directional mounting or other special positional adjustment of the spring for generating the support force, as described earlier, is unnecessary. This makes the installation of the support device, and by extension the electromagnetic switching device or valve device, relatively easy. By selecting the appropriate material for the transmission member, corrosion and wear issues do not need to be considered during spring design or armature material selection. Since a spring guide is not required for the armature body, spring mounting errors are also prevented.

[0014] In one embodiment, the support device is configured such that a preload is applied to a support force generating member, such as a spring member, so that the transmission member is lifted off the surface of the guide device. In other words, after the assembly of the components, the support device is configured such that an additional preload is applied to a support force generating member, such as a spring member, so that the transmission member, such as a sphere, is lifted off the plastic seating surface.

[0015] In one embodiment, the transmission member is formed such that on the second side, at least one force introduction point is located at at least one predetermined contact point on the armature body. By disengaging using the transmission member to which a preload force has been applied, the force introduction can be precisely, preferably, located at a predetermined point on the armature body.

[0016] In one embodiment, the transmission member is formed with a rounded shape on the second side, at least partially. In particular, the transmission member is preferably formed at least partially spherical, especially as a sphere. The transmission member may also be formed at least partially cylindrical, rectangular, or in another form to suit its function, thereby being able to suit the requirements imposed on the load-bearing member, such as a spring member of a particular configuration, and the shape of the armature body.

[0017] In one advantageous embodiment, the mechanical separation of the bearing force generating member from the armature body can be performed, for example, via a sphere. The sphere is inexpensive to procure and does not require attention to orientation, making it extremely easy to handle and install. Furthermore, the spherical shape creates a predetermined contact point that also allows for a certain degree of conformity. The sphere is, for example, placed in a type of ball guide within a guide device, which ensures contact of the sphere with the armature body beyond manufacturing tolerances. On the opposite side, a spring member, such as a coil spring, is positioned with preload applied.

[0018] In one embodiment, the support force generating member has at least one spring member. In one embodiment, the at least one spring member is formed as a coil spring.

[0019] In one embodiment, the support force generating member has at least one spring member, and the guide device is configured such that the motion of at least one spring member in the direction of the generated preload force is pure translational motion in the axial direction of the guide device. This is advantageous because the motion of the spring member is converted into pure translational motion in the axial direction of the guide device, which also leads to a defined and calculable load condition for the spring member.

[0020] In one embodiment, the guide device is tapered on the second side of the transmission member. This allows for more precise positioning of the transmission member relative to a predetermined force introduction point. Furthermore, it makes it difficult or impossible for the transmission member to be undesirably pushed out of the guide device by preload force, for example, before or during installation of the support device in a switching device or valve device. In one embodiment, the guide device is formed from two parts. Therefore, forced demolding in the manufacturing mold is not required.

[0021] In one embodiment, the guide device is tapered on the second side of the transmission member, thereby preventing the transmission member from moving out of the guide device based on the preload force when the support device is not attached. This prevents the transmission member from flying out of the guide device when a preload force is applied. Therefore, it is also possible to install the pre-configuration group upside down.

[0022] In one embodiment, the support device is formed as a pre-assembled group of components that can be installed as a component group within an electromagnetic switching device. By forming the support device as a pre-assembled group of components, i.e., a unified functional unit, for example, a spring member can be pre-installed, eliminating the need to consider the installation direction.

[0023] In one embodiment, the armature body is positioned and supported within a switching device or valve device by a support device at one end face of the armature body.

[0024] In one embodiment, the armature body is formed as a plate armature. In this case, the plate armature may be advantageously formed as a tilting armature.

[0025] In one embodiment, the electromagnetic switching device or valve device is formed as an electromechanical relay or solenoid valve, particularly a tilting armature valve.

[0026] In one embodiment, an electromagnetic switching device or valve device is formed as an electromagnetic valve for a pressure regulating module of a vehicle.

[0027] The embodiments described herein may be used in parallel or may be used in any combination with each other.

[0028] The present invention will be described in more detail below based on the drawings showing embodiments of the present invention.

Brief Description of the Drawings

[0029] [Figure 1] It is a schematic cross-sectional view showing an exemplary tilting armature valve according to one embodiment of an electromagnetic valve device according to the present invention. [Figure 2] It is a schematic cross-sectional view showing one embodiment of a support device according to the present invention that can be used in, for example, the tilting armature valve shown in FIG. 1.

[0030] Figure 1 shows a simplified cross-sectional view of a tilting armature valve 100 according to one embodiment of the present invention. Embodiments of the present invention will be described in more detail below based on the illustrated tilting armature valve 100. However, those skilled in the art will recognize that the present invention is basically applicable to other electromagnetic switching or valve devices that have an electromagnetic actuator similar to the tilting armature valve 100 of the present invention and an armature body that is movable based on a magnetic field as a switching member or valve member, and the armature body is configured to cooperate with an electromagnetic actuator for operating the armature body. The support devices of the form of the present invention described in more detail below can be used in such switching or valve devices, such as electromagnetic relays or solenoid valves, to fix and support each armature body in position by applying a preload force, as illustrated below based on the tilting armature valve 100. In this regard, it should be noted that those skilled in the art are aware of the basic functional forms of electromagnetic switching or valve devices, which include an armature body that is movable based on a magnetic field and serves as a switching or valve member, particularly with respect to electromagnetic actuators that cooperate with a movable armature body.

[0031] The tilting armature valve 100 may be, based on the basic principle, one embodiment of the tilting armature valve 100 shown in German Patent Application Publication No. 102016105532. In one embodiment, it may be the solenoid valve denoted by reference numeral 100 in Figure 1 of the above specification. However, other embodiments relating to solenoid valves, such as those described in the other publications mentioned above, are also possible. The configuration and use of the solenoid valve and its components as described in German Patent Application Publication No. 102016105532 are also part of the disclosure of the present invention by reference.

[0032] Figure 1 shows a cross-sectional view of a tilting armature valve 100, in which the armature body is in a first position. The tilting armature valve 100 includes a coil member 110, an armature body (or simply armature) 115, one embodiment of a support device 10 according to the present invention, a sealing member 125, and a cover shell (or generally a housing portion) 130. In this case, the coil member 110 (which generally forms an electromagnetic actuator) includes at least one coil core 135 and a coil 140 arranged radially to surround the coil core 135. One end face of the armature 115 is supported by the support device 10. The armature 115 is movable between a first position 147 and a second position which is lifted or pulled in by the coil member 110, the second position which opens an outlet 155 for the fluid 158 (not shown in Figure 1). In this case, the armature 115 is formed to move from the first position 147 to the lifted second position when the coil 140 is actuated. When the coil 140 is actuated, the armature 115 can be held in the second position. A sealing member 125 is further positioned on the side of the armature 115 opposite to the coil member 110. The cover shell 130 has a valve seat 150 with an outlet 155 and an inlet 157 for the fluid 158. In this case, when the armature 115 is positioned in the illustrated first position 147, the outlet 155 can be fluid-tightly closed by the sealing member 125. In this case, the sealing member 125 can also act as a damper to prevent the armature 115 from colliding with the valve seat 150. In this case, the sealing member 125 may be attached to the armature 115 or the support member by vulcanization.

[0033] In one exemplary embodiment, the armature 115 has at least a partially rounded protrusion 160 on a support portion 162, in which case the protrusion 160 is advantageously engaged with a recess 165 or opening located in the portion of the housing 170 of the tilting armature valve 100 that is opposite the protrusion 160. This allows the armature 115 in the recess to slide from a first position 147 to a second position in a single movement after current is connected by the coil 140, and at the same time to be held in a fixed position within the housing 170 or against the cover shell 130. Advantageously, the recess is formed in a trapezoidal shape, thereby causing minimal friction as the protrusion slides across the surface of the recess 165. The recess 165 may be manufactured from, for example, a plastic material, which may allow for very simple and inexpensive manufacturing.

[0034] The support device 10 is positioned on the side of the armature 115 opposite to the coil 140. In this case, the support device 10 is used to press the armature 115 against the housing 170 of the coil member 110 without any play. Depending on the configuration, the pressing may be basically performed against another suitable component of the tilting armature valve 100. The armature 115 can be fixed in place by the support device 10, so that the armature 115 is held in place by the support device 10. This has the advantage that a substantially constant preload force can be applied to the armature 115, and that the force applied to the armature 115 from the support device 10 can be introduced to the armature 115 as close as possible to the force introduction point of the armature 115, which is located on the axis of rotation. The support device 10 is only roughly shown in Figure 1 and will be described in more detail below in relation to Figure 2.

[0035] Figure 2 shows a schematic cross-sectional view of one embodiment of the support device 10 according to the present invention, which may be used, for example, in the tilting armature valve 100 shown in Figure 1. In this case, the configuration of the individual components, such as the surrounding housing portion 130, the armature 115, and the coil core 135, has been changed, which also indicates that the support device 10 can be used in electromagnetic switching devices or valve devices of basically various configurations.

[0036] In the illustrated embodiment, the armature 115 is formed as a plate armature similar to that used in the tilting armature valve 100 shown in Figure 1, as in the embodiment shown in Figure 1. As described with respect to Figure 1, the armature 115 is fixedly supported within the tilting armature valve 100 by a support device 10 on one side, in this embodiment at the end face, and is moved between a first position and a second position by the actuation of the coil 140.

[0037] The support device 10 has a guide device 13 that at least partially surrounds the transmission member 12. Furthermore, the support device 10 has a support force generating member that generates a preload force F for supporting the armature 115. In one embodiment, the support force generating member has or is formed as a coil spring, for example, at least one spring member 11 in the form of a coil spring. The coil spring 11, in a well-known form, generates a preload force F in the direction of the axis 16 of the coil spring 11 when compressed. The guide device 13 may also be fixed or sealed to the housing portion 130 by a sealing member 31, for example, in the form of an O-ring. Basically similarly, another type of spring member may be used to generate the preload force F.

[0038] The transmission member 12 is preferably formed in the shape of a sphere and forms a separate component from the spring member 11, and in particular, is not integrally molded with or integrated with the spring member 11. The transmission member 12 has a first side 128 and a second side 129 located on the opposite side. In this case, the first side 128 faces the coil spring 11 and the second side 129 faces the armature 115. The transmission member 12 is pressed in the direction of the armature 115 by the preload force F generated by the coil spring 11, contacts the armature 115 at the force introduction point 20 of the armature, and is used to fix the position and support the armature 115 in the tilting armature valve. In this case, the transmission member 12 is in contact with the armature 115 at the force introduction point 20 of the armature, such that the force introduction point 20 is mechanically disconnected from the coil spring 11. In this embodiment, the transmission member 12 is not attached to or mechanically fixed to the armature 115 by, for example, screw fastening or other fastening means, but merely in contact with the armature 115 and is pressed against the armature 115 in a lateral direction relative to the armature surface based on the preload force F. In this way, the required support force is generated. In this case, the transmission member 12 is formed on the second side 129, for example, based on a rounded shape, such that the force introduction point 20 is defined on a predetermined contact point on the armature 115. In this case, the guide device 13 is used to guide and position the transmission member 12 at the force introduction point 20 by surrounding the transmission member 12 at least partially, for example, in the form of a border portion 14, thereby constraining the transmission member 12 by the guide device 13 to be within the plane of the armature surface, apart from small play or manufacturing tolerance positions.

[0039] Preferably, the transmission member 12 is formed with at least a partial rounding on the second side 129, thereby allowing for the precise definition of the force introduction point 20. As described, the transmission member 12 is preferably formed as a sphere, as shown in Figure 2.

[0040] The guide device 13, which may be molded from plastic, has a passage 15 (formed, for example, by a recess provided in the plastic body), the passage 15 defines the axial direction of the guide device 13, and the transmission member 12 is at least partially held within the passage 15. A coil spring 11 may also be located at least partially within the passage 15, so that the axis 16 of the coil spring 11 coincides with the longitudinal axis of the passage 15. Advantageously, in this way, it is achieved that the motion of the coil spring 11 in the direction of the generated preload force F is purely translational motion in the axial direction.

[0041] In one embodiment, the guide device 13 is tapered at least on the second side 129 of the transmission member 12, for example, by giving the edging portion 14 a correspondingly tapered shape. This prevents the transmission member 12 from moving out of the guide device 13 and falling off based on the preload force F when the support device 10 is not attached. This makes it possible to pre-assemble the support device 10 as a component group, and then install the support device 10 as a component group upside down inside the tilting armature valve 100 without the transmission member 12 falling off the guide device 13.

[0042] The support device 10 was described in relation to a solenoid valve in the form of a tilting armature valve 100, based on Figure 1. When used in an electromagnetic switching device, such as a relay, the armature 115 shown in Figure 2 can be used as an electrical switching member to close or open electrical contacts, for example, as well as valve opening. The above-described type of support force generation by the support device 10 can be applied to virtually any electromagnetic tilting / flap armature valve device and switching device.

[0043] In summary, the support device 10 according to the present invention mechanically disconnects the force introduction point 20 in the armature 115 from the spring member 11 by the transmission member 12. This type of support force generating means for a support position to which a spring load is applied can be applied to virtually all embodiments of electromagnetic tilt-flap armature valve devices and switching devices. By disconnecting using the transmission member 12 with a spring preload, it is possible to pinpoint the force introduction to a precise point in the armature 115. Furthermore, the motion of the spring member is converted into pure translational motion in the axial direction, which also leads to a defined and calculable load condition for the spring member 11. Appropriate material selection for the transmission member 12 eliminates the need to consider corrosion and wear during spring design or armature material selection. Since a spring guide is not required for the armature 115, mounting errors of the spring member 11 are also prevented. Based on a unified functional unit, the spring member 11 may be pre-mounted, and there is no need to consider the mounting direction.

[0044] Mechanical disconnection of the spring from the armature may be performed, for example, via a transmission member 12 in the form of a sphere. Such a component can be procured inexpensively and does not require attention to orientation, making it extremely easy to handle and install. Furthermore, the sphere shape creates a predetermined contact point that also allows for a certain degree of conformability. The sphere 12 may be placed in a kind of ball guide (formed by the passage 15 and rim 14 of the guide device 13 in the embodiment shown in Figure 2), and the ball guide ensures that the sphere 12 makes contact with the armature 115 beyond manufacturing tolerances. On the opposite side of the sphere, a coil spring 11 may be positioned with preloading. Alternatively, the transmission member 12 may be molded and formed to suit its function in a cylindrical, rectangular, or other form, thereby being able to conform to the requirements imposed on the shapes of the spring member 11 and the armature 115.

[0045] For example, the guide device 13 in the form of a plastic part 13 may be manufactured from two parts. Therefore, forced demolding in the mold is not required during manufacturing. In this case, in a mold consisting of two parts, the mold division is considered to be located in the area of ​​the mounting space for the spring member 11. [Explanation of symbols]
