Description

[Technical field]

[0001] The present invention relates to a support device for positionally fixing and supporting an armature body of an electromagnetic switching device or valve device by applying a preload force, and to an electromagnetic switching device or valve device equipped with such a support device.

[0002] Such electromagnetic switching or valve devices are known, for example, in the form of electromagnetic relays or electromagnetic solenoid valves. Electromagnetic valves, for example in the form of tilting armature valves, are used, for example, as pressure-regulating control valves in vehicles, for example in commercial vehicles or passenger transport buses. For example, a brake system for a vehicle with an electronic service brake system comprises at least one pressure-regulating control valve.

[0003] A tilting armature valve is known, for example, from DE 10 2016 105 532 A1. The tilting armature valve has a coil member with a coil core, a coil arranged radially surrounding the coil core, and an armature supported by a support at one end face of the armature body, where the armature is movable from a first position to a second position, in particular by supplying an electric current to the coil. Furthermore, a valve seat with an outlet and an inlet for a fluid are provided, where the outlet is fluid-tightly closable 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 the housing of the tilting armature valve.

[0004] Furthermore, other designs of solenoid valves are known, as for example described in DE 102014115207 A1, DE 102018123997 A1 or DE 102014115206 A1.

[0005] In electromagnetic switching devices or valve devices, for example in the solenoid valves of the above-mentioned construction type, conventional armature guides and armature supports are usually formed via positive locking, spring-loaded supports or fixed flexible supports. In the case of tilting armatures in relays, supports similar to simple hinges are often used, which are fixed in position during the installation process by plastic deformation. In contrast, in the case of solenoid valves, "cantilevered" double-acting armatures are widespread. In electromechanical switching elements with small working strokes, thin leaf springs are rigidly connected and move within their elastic range during use. In valve technology, tilting armatures often have spring-loaded supports in order to operate without play and without wear.

[0006] In the case of spring-preloaded supports, there is in most cases an influence of the support spring on the armature body and thus on the switching or valve member. This influence can be positive, neutral or negative for the function, depending on the manufacturing tolerances and the installation. In particular, when used as actuators in control and regulating circuits, high reproducibility and a constant switching action over mass production are essential. For economic reasons, typical coil springs are often used for this purpose. However, these spring elements have the disadvantage that the force introduction point is not located in the center on the spring central axis, but is always eccentric due to the manufacturing. The orientation and installation of the spring is very laborious, resulting in different force application points. In addition, spring centering is also necessary, since the spring usually does not only perform an axial movement on the tilting armature. This centering makes the installation more difficult and increases the risk of failure due to installation errors.

[0007] Furthermore, a precise design of the spring is not possible with the current methods due to the superposition of the translational and rotational movements of the tilting armature. When using directly acting springs for mounting, the mounting direction must also be taken into account, since the support spring is generally located on the opposite side of the armature stroke from the return spring. Therefore, additional measures must be taken to hold the spring element in its intended position until it is fully mounted.

[0008] The object of the present invention is to provide a support device for positionally fixing and supporting the armature body of an electromagnetic switching device or valve device by applying a preload force, which allows for the introduction of a force at a defined support position on the armature body with relatively little installation effort, as well as an electromagnetic switching device or valve device equipped with such a support device.

[0009] The present invention relates to a support device for positionally fixing and supporting an armature body of an electromagnetic switching or valve device by applying a preload force as well as to an electromagnetic switching or valve device provided with such a support device according to the attached independent claims. Advantageous configurations and refinements of the invention are set out in the dependent claims and in the following description.

[0010] In particular, one embodiment of the present invention relates to a support device for applying a preload force to fix and support an armature body of an electromagnetic switching device or valve device, the support device including a support-force generating member that generates a preload force for supporting the armature body, and a transmission member formed separately from the support-force generating member, the transmission member being pressed toward the armature body by the preload force generated in an attached 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 an attached state of the support device and contacting the armature body at least one force introduction point of the armature body such that the force introduction point is mechanically decoupled from the support-force generating member, the support device further including a guide device at least partially surrounding the transmission member and formed 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 or valve member cooperating with the electromagnetic actuator for actuating the armature body, and a support device according to the present invention, wherein the armature body is supported at one side in a fixed position within the switching or valve device by the support device and is movable from a first position to a second position by actuation of the electromagnetic actuator.

[0012] The present invention thus makes it possible to determine the force introduction at a predefined support location on the armature body with relatively small installation efforts even when different force generating elements are used, for example spring elements of different configurations, etc. This is made possible by the use of a transmission element according to the present invention, which contacts at least one force introduction point of the armature body at a support location of the armature body, the force introduction point of the armature body being mechanically decoupled from the force generating elements by the transmission element.

[0013] Such a type of support force generating means for the support position, where the preload force, in particular the spring load, is applied, can be applied in principle in all electromagnetic tilt-flap armature solenoid valve devices and switching devices. By decoupling with the preloaded transmission element, it is possible to determine the force introduction at a predefined point on the armature body. At the same time, oriented mounting or other special positioning of the spring for generating the support force, as mentioned at the beginning, is not necessary. This allows the mounting of the support device and thus the electromagnetic switching device or valve device with relatively little effort. Due to the suitable material selection of the transmission element, considerations regarding corrosion and wear can be avoided when designing the spring or when selecting the armature material. Since no spring guide is required for the armature body, spring mounting errors are also prevented.

[0014] In one embodiment, the support device is configured in such a way that the force generating member, e.g. a spring member, is preloaded, so that the transmission member is lifted off the surface of the guide device, in other words, the support device is configured in such a way that after assembly of the assembly, the force generating member, e.g. in the form of a spring member, is additionally preloaded, so that the transmission member, e.g. in the form of a ball, is lifted off the plastic seat.

[0015] In one embodiment, the transmission member is formed on the second side such that at least one force introduction point is defined at at least one predefined contact point on the armature body. Decoupling with the preloaded transmission member allows the force introduction to be defined at a precise, preferably predefined, point on the armature body.

[0016] In one embodiment, the transmission element is at least partially rounded at the second side. In particular, the transmission element is preferably at least partially spherical, in particular as a sphere. The transmission element may also be at least partially cylindrical, rectangular or otherwise functionally shaped and adapted to the requirements imposed on the force generating element, e.g. the spring element of a particular configuration type, or the shape of the armature body.

[0017] In one advantageous embodiment, the mechanical decoupling of the support force generating element from the armature body can be achieved, for example, via a ball. Balls are very easy to handle and install, since they can be procured inexpensively and do not require attention to orientation. Furthermore, the shape of the ball creates a defined contact point, which also allows a certain degree of matching effect. The ball is arranged, for example, in a kind of ball guide in the guide device, which ensures the contact of the ball with the armature body beyond the manufacturing tolerance position. On the opposite side, for example, a spring element, for example a coil spring, is arranged with a preload.

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

[0019] In one embodiment, the support force generating member comprises at least one spring member and the guide device is configured in such a way that the movement of the at least one spring member in the direction of the generated preload force is a pure translational movement in the axial direction of the guide device, whereby the movement of the spring member is advantageously converted into a pure translational movement in the axial direction of the guide device, which also leads to defined and calculable load conditions for the spring member.

[0020] In one embodiment, the guide device is tapered on the second side of the transmission member. This allows the positioning of the transmission member relative to a given force introduction point to be more precisely defined. Furthermore, it is possible to make it difficult or prevent the transmission member from being undesirably pushed out of the guide device by preload forces, for example before or during the mounting of the support device in a switching device or valve device. In one embodiment, the guide device is formed in two parts. Thus, no forced demoulding is required in the production mold.

[0021] In one embodiment, the guide device is tapered on the second side of the transmission member, which prevents the transmission member from moving out of the guide device under the preload force when the support device is not attached, so that the transmission member cannot jump out of the guide device under the preload force. Thus, the pre-assembly can be installed upside down.

[0022] In one embodiment, the support device is formed as a preassembled group that can be mounted as a group in the electromagnetic switching device. By forming the support device as a preassembled group, i.e. as a complete functional unit, for example, the spring element can be pre-mounted and no considerations regarding the mounting direction are required.

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

[0024] In one embodiment, the armature body is configured as a plate armature, which may then advantageously be configured as a tilting armature.

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

[0026] In one embodiment, the solenoid switching or valving device is configured as a solenoid valve for a pressure regulation module of a vehicle.

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

[0028] The invention will now be explained in more detail on the basis of the illustrated drawings, which represent embodiments of the invention. [Brief description of the drawings]

[0029] [Figure 1] 1 is a schematic cross-sectional view of an exemplary tilting armature valve according to one embodiment of an electromagnetic valve device in accordance with the present invention; [Diagram 2] 2 is a schematic cross-sectional view of one embodiment of a support device according to the present invention, such as may be used in the tilting armature valve shown in FIG. 1; FIG.

[0030] FIG. 1 shows a simplified cross-sectional view of a tilting armature valve 100 according to one embodiment of the present invention. In the following, an embodiment of the present invention will be described in more detail based on the illustrated tilting armature valve 100. However, a person skilled in the art will recognize that the present invention can also be applied to other electromagnetic switching or valve devices that essentially have an electromagnetic actuator similar to the tilting armature valve 100 of the present invention and an armature body movable based on a magnetic field as a switching or valve member, and the armature body cooperates with an electromagnetic actuator for actuating the armature body. A support device of the type of the present invention, which will be described in more detail below, can be used in such switching or valve devices, such as an electromagnetic relay or solenoid valve, to positionally fix and support each armature body with a preload force, as will be described below by way of example based on the tilting armature valve 100. In this connection it should be pointed out that the basic functional form of an electromagnetic switching or valve device having an armature body as a switching or valve member movable by a magnetic field is known to a person skilled in the art, in particular with regard to an electromagnetic actuator cooperating with a movable armature body.

[0031] Based on the basic principle, the tilting armature valve 100 may be an embodiment of the tilting armature valve 100 shown in DE 102016105532 A1. In this case, it may in one embodiment refer to the solenoid valve designated with the reference number 100 in FIG. 1 of said specification. However, other embodiments are also conceivable in connection with solenoid valves, for example as described in the other publications mentioned above. In this regard, the construction of the solenoid valve and its components as well as their use as described in DE 102016105532 A1 are also made part of the disclosure of the present invention by reference.

[0032] 1 shows a cross-sectional view of a tilting armature valve 100, in which the armature body is located in a first position. The tilting armature valve 100 comprises a coil member 110, an armature body (or armature for short) 115, one embodiment of a support device 10 according to the present invention, a seal member 125, and a cover shell (or generally a housing part) 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 to surround the coil core 135 in the radial direction. One end surface 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 actuated by the coil member 110 and is lifted or attracted, the second position opening an outlet 155 for the fluid 158 (not shown in FIG. 1). In this case, the armature 115 is configured to be moved from the first position 147 to the lifted second position upon actuation of the coil 140. When the coil 140 is actuated, the armature 115 can be held in the second position. A sealing member 125 is further arranged on the side of the armature 115 opposite the coil member 110. The cover shell 130 is formed with a valve seat 150 with an outlet 155 and an inlet 157 for the fluid 158. In this case, when the armature 115 is arranged in the illustrated first position 147, the outlet 155 can be closed in a fluid-tight manner by the sealing member 125. In this case, the seal member 125 may also act as a damper member to prevent collision of the armature 115 against the valve seat 150. In this case, the seal member 125 may be attached to the armature 115 or the support member by vulcanization.

[0033] The armature 115, in one exemplary embodiment, has at least a partially rounded ridge 160 on the support part 162, which is advantageously engaged in a recess 165 or opening arranged in a part of the housing 170 of the tilting armature valve 100 located opposite the ridge 160. This allows the armature 115 in the recess to slide from the first position 147 to the second position in one movement after the current is connected by the coil 140, while at the same time being held in a fixed position in the housing 170 or against the cover shell 130. Advantageously, the recess is formed trapezoidal, so that a minimum of friction occurs when the ridge slides over the surface of the recess 165. The recess 165 may be manufactured, for example, from a plastic material, which may be very simple and inexpensive to manufacture.

[0034] The support device 10 is arranged on the side of the armature 115 opposite the coil 140. In this case, the support device 10 is used to press the armature 115 against the housing 170 of the coil element 110 without play. Depending on the type of construction, the pressing can basically also be performed against other suitable components of the tilting armature valve 100. The armature 115 can be fixed in position by the support device 10, so that the armature 115 is held in a predetermined position 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 by the support device 10 to the armature 115 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 illustrated in FIG. 1 and will be explained in more detail below in connection with FIG. 2.

[0035] Figure 2 shows a schematic cross-sectional view of one embodiment of the support device 10 according to the invention, as can be used, for example, in the tilting armature valve 100 shown in Figure 1. In this case, the design of the individual components, such as the surrounding housing part 130, the armature 115 and the coil core 135, is modified, which also makes it clear that the support device 10 can basically be used in electromagnetic switching devices or valve devices of various designs.

[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 Fig. 1, for example, as in the embodiment shown in Fig. 1. The armature 115 is supported in a fixed position within the tilting armature valve 100 at one side, in this embodiment an end face, by the support device 10 as described with respect to Fig. 1, and is moved between a first position and a second position by the operation of the coil 140.

[0037] The support device 10 comprises a guide device 13 which at least partially surrounds the transmission member 12. The support device 10 further comprises a support force generating member which generates a preload force F for supporting the armature 115. In one embodiment, the support force generating member comprises at least one spring member 11, for example in the form of a coil spring, or is formed as a coil spring. The coil spring 11 generates a preload force F in a compressed state in the direction of the axis 16 of the coil spring 11 in a known manner. The guide device 13 may also be fixed or sealed relative to the housing part 130 by a sealing member 31, for example in the form of an O-ring. Basically, other types of spring members may also be used to generate the preload force F.

[0038] The transmission member 12 is preferably formed in the form of a sphere and forms a separate component from the spring member 11, in particular not molded or integrated into the spring member 11. The transmission member 12 has a first side 128 and an oppositely located second side 129, in which the first side 128 faces the coil spring 11 and the second side 129 faces the armature 115. The transmission member 12 is pressed towards the armature 115 by the generated preload force F of the coil spring 11 and comes into contact with the armature 115 at the force introduction point 20 of the armature, and is thus used for fixing and supporting the armature 115 in the tilting armature valve. In this case, the transmission member 12 contacts the armature 115 at the force introduction point 20 of the armature, such that the force introduction point 20 is mechanically decoupled from the coil spring 11. In this embodiment, the transmission member 12 is not attached to the armature 115 or mechanically fixed thereto, for example by means of a screw fastening or another fastening means, but merely contacts the armature 115 and is pressed against the armature 115 transversely to the armature surface due to 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 due to a rounded shape, in such a way that the force introduction point 20 is defined on a predefined 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 at least partially surrounding the transmission member 12, for example in the form of a edging portion 14, so that the transmission member 12 is constrained by the guide device 13 in the plane of the armature surface, apart from small play or manufacturing error positions.

[0039] Preferably, the transmission member 12 is formed at least partially rounded on the second side 129, which allows to define a precise force introduction point 20. As explained, the transmission member 12 is preferably formed as a sphere, as shown in FIG.

[0040] The guide device 13, which may be molded from plastic, has, for example, a passage 15 (formed, for example, by a recess in the plastic body), which defines the axial direction of the guide device 13 and in which the transmission member 12 is at least partially held. The coil spring 11 may also be located at least partially in 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 movement of the coil spring 11 in the direction of the generated preload force F is a purely translational movement 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 providing the edging 14 with a corresponding tapered shape, thereby preventing the transmission member 12 from moving out of the guide device 13 due to the preload force F in the unmounted state of the support device 10. This allows the support device 10 to be preassembled as a group, and then the support device 10 can also be mounted as a group upside down in the tilting armature valve 100 without the transmission member 12 falling out of the guide device 13.

[0042] The support device 10 has been described with reference to Fig. 1 in connection with a solenoid valve in the form of a tilting armature valve 100. For use in solenoid switching devices, for example in relays, the armature 115 shown in Fig. 2 can be used as an electrical switching element, for example for closing or opening an electrical contact as well as a valve opening. The above-mentioned type of support force generation by the support device 10 can be applied in principle in all solenoid tilt-flap armature valve devices and switching devices.

[0043] In summary, the support device 10 according to the invention therefore mechanically decouples the force introduction point 20 on the armature 115 from the spring element 11 by the transmission element 12. Such a type of support force generating means for the spring-loaded support position can be applied in principle in all embodiments of electromagnetic tilt-flap armature valve devices and switching devices. Decoupling by means of the spring-preloaded transmission element 12 makes it possible to determine the force introduction at a precise point on the armature 115. Furthermore, the movement of the spring element is converted into a pure translational movement in the axial direction, which also leads to defined and calculable load conditions for the spring element 11. Due to the appropriate material selection of the transmission element 12, considerations regarding corrosion and wear can be avoided during the spring design or when selecting the armature material. Since no spring guides are required for the armature 115, mounting errors of the spring element 11 are also prevented. Due to the integrated functional unit, the spring element 11 can be pre-mounted and the mounting direction does not have to be taken into account.

[0044] The mechanical decoupling of the spring from the armature can take place via a transmission member 12, for example in the form of a ball. Such components are very simple in terms of handling and installation, since they can be procured inexpensively and do not require attention to orientation. Furthermore, the shape of the ball results in a defined contact point, which also allows a certain degree of adaptation effect. The ball 12 can be placed in a kind of ball guide (in the embodiment shown in FIG. 2, formed by the passage 15 and the edge 14 of the guide device 13), which ensures the contact of the ball 12 with the armature 115 over the manufacturing tolerance position. On the opposite side of the ball, the coil spring 11 can be arranged preloaded. Alternatively, the transmission member 12 can be formed cylindrically, rectangularly or in another form shaped and adapted to the function, so that it can be adapted accordingly to the requirements imposed on the shape of the spring member 11 and the armature 115.

[0045] The guide device 13, for example in the form of a plastic part 13, can also be produced in two parts, so that no forced demolding of the mould is necessary during production. In this case, in a two-part mould, the mould part is considered to be located in the region of the mounting space for the spring element 11. [Explanation of symbols]
