Description

  The present invention is an apparatus for controlling a medium, which is coupled to at least one drive module having at least two outlets that are axially offset and one of the outlets of the drive module, respectively, for conveying the medium At least two pump modules, at least one valve module with circuitry, provided for controlling the medium conveyed by the pump module, and an axis determined by the outlet of the drive module The present invention relates to the apparatus including the arrangement configuration of the valve modules that are spatially shifted from each other.

  In general, state-of-the-art ABS / ESP brake control systems use rotating motors and eccentrics on the driven shaft to drive hydraulic pump elements that are radially arranged and in most cases operate linearly. The These elements carry the working medium from or to the wheel brake via a valve. As a central component of the ABS / ESP brake control system, a rectangular parallelepiped block made of aluminum in most cases is used as the entire casing. In this case, the component is inserted or attached into the block (eg into the hole) from almost all sides. Both the valve module and the pump module are integrated here. These components are most often configured cylindrically or have a predetermined insertion geometry or closure geometry. The drive module is similarly configured in a cylindrical shape, and is connected to a rectangular parallelepiped block with an end face having an outlet.

  From the technical level, Patent Document 1 in which a vibration compressor including an oscillator motor is described in various arrangements of components is also known. In its preferred configuration, a drive module with two outlets is described, in which two reciprocating pistons driven by the drive module and used for refrigerant compression run.

German Patent Application Publication No. 1942945

  The device for controlling a medium according to the invention uses at least one drive module, at least two pump modules and at least one valve module. The drive module has at least two outlets that are offset in the axial direction, the outlets being arranged on opposite end faces of the drive module. Each pump module is coupled to one of the outlets of the drive module. The pump module is driven by the drive module to carry the medium (eg, fluid). Furthermore, a valve module is provided. The valve module is provided with a circuit for controlling the medium conveyed by the pump module. The valve module is arranged spatially offset with respect to the central axis determined by the outlet of the drive module.

  This device for controlling the media is preferably characterized in that the geometry and arrangement of the pump module and the drive module are replaced with each other and with respect to the valve module. This advantage relates in particular to the possibility to use the new closing geometry of the module, for example two opposing outlets provided in the drive module. One U-shaped pump casing or two end faces facing each other by supplementing a rectangular-shaped valve casing around a plurality of L-shaped, rectangular parallelepiped or block shaped pump casings, for example It is possible to connect a cylindrical drive module having an outlet.

  Instead of, and as a complement to, the purely geometric configuration and arrangement of modules, the device for controlling a medium according to the invention is advantageously a module that is conventionally incorporated in one casing. Can also be separated into a plurality of unique casings. In addition, a supplement of the casing around the geometric elements and a division of the original or supplemented casing takes place. This can advantageously affect the assembly of the entire system.

  In particular, according to the invention, at least one of the pump modules and the valve module form a structurally separated unit. By separating the pump module together with the valve module from one common casing, the structural space required for the valve module can be reduced. The structural separation can also have an advantageous effect on assembly. The two modules can be connected via a (removable) screw connection or crimping. When the drive module is arranged offset with respect to the valve module, or when both modules are coupled via the pump module, a lateral force is generated in the pump module by the drive module in the direction of the driven axis. This lateral force requires screwing together of the pump modules or securing them to the valve module.

  In an advantageous configuration of the device for controlling the medium, at least one of the pump modules forms a structural unit that is integrally implemented with the valve module. The integral implementation offers the advantage that no auxiliary coupling is required as in the two-part implementation.

  The device for controlling a medium according to the invention is advantageously characterized in that the pump module at least partly surrounds the drive module. Surrounding can provide a number of advantages. One is the reduction of the required structural space. This effect can be enhanced, for example, by the drive module being at least partially surrounded by the valve module (this can be achieved, for example, by partially sinking). On the other hand, the positioning or orientation of the modules is also set by surrounding. Furthermore, both can be held and / or force can be transmitted.

  In a further advantageous configuration of the device for controlling the medium according to the invention, the pump module surrounds the outlet of the drive module. In this case, a unique pump module is attached to each outlet of the drive module. Each pump module outlet is guided by a pump element which is connected to a common armature carrier. The pump element is configured, for example, as a piston provided at the end of the armature carrier. Advantageously, an integrated implementation is possible. Alternatively, a multi-part implementation can also be applied. These pump elements driven by the drive module act inside the pump module through the outlet of the drive module. By providing the pump elements spatially close to the respective outlets, it is possible to shorten the push rods or armature carriers necessary for force transmission, or generally suitable coupling elements. This is advantageous because the push rod or the coupling element does not break.

  The device for controlling a medium according to the invention advantageously has a pump module arranged in a casing, which casing is substantially U-shaped, L-shaped, cuboid-shaped or block-shaped. . It is advantageous to use a U-shaped casing for both pump modules. This is because the pump module can at least partially surround the drive module and can surround the two outlets provided at the opposite end faces of the drive module. By using an L-shaped casing, it is possible to partially enclose the drive module as well. The use of an L-shaped casing is advantageous in terms of its assemblability compared to a U-shaped casing. Furthermore, the present invention uses the pump casing in a rectangular parallelepiped shape or generally a block shape.

  In addition, according to the device for controlling a medium according to the invention, advantageously, at least one of the pump modules is arranged in a single casing, which casing is substantially U-shaped. . An integrally implemented U-shaped pump casing is advantageous because it can absorb forces that are drawn into the pump module through the pump element in the direction of the central axis of the outlet of the drive module.

  As an alternative, the pump module is arranged in a plurality of casings, in which case these casings are combined and configured in a substantially U-shape. In this case, each pump module has its own casing. The U-shaped division can in this case be carried out centrally or eccentrically. In this case, the individual casings are substantially L-shaped. The use of a plurality of casings is advantageous in that the assembly can be done easily and easily. Absorption of the lateral force described above is made possible by connecting these casings together, for example by screw connection.

  In another alternative embodiment, the plurality of casings are configured in a substantially rectangular parallelepiped shape or block shape. By reducing the U shape or L shape to a rectangular parallelepiped shape or block shape, the structure volume can be reduced. Besides reducing the structure volume, material savings in manufacturing have also been found to be advantageous.

  The block-shaped pump casing is coupled to the valve module via a coupling portion, for example, via a screw coupling portion. In addition to the screw coupling portion, a press coupling portion, a rivet coupling portion and / or a self-clinching coupling portion are provided alternatively. In the case of a block-shaped pump casing, the absorption of the lateral force described above can be sufficiently absorbed by fixing the pump module together with the valve module.

  The structural separation of the two elements, the pump module and the valve module, ie the implementation from two parts, means that a cutting point is created for guiding the medium pumped into the valve module by the pump module. I mean. In order to avoid leakage, it is advantageous to provide a packing for the components guiding the media. In an advantageous configuration, an O-ring is incorporated between the pump module casing and the valve casing. In this case, a unique packing is provided for both the medium supply pipe and the discharge pipe. The O-ring is inserted into the notch provided for these casings that are screwed together. Accordingly, the screw coupling portion generates a sealing force and a holding force.

  In an advantageous embodiment, the single casing or the plurality of casings of the pump module is configured as a connection between a valve module that is configured in a particularly rectangular parallelepiped shape and a drive module that is configured in a particularly cylindrical configuration. This coupling can take place with respect to the coupling of the different insertion geometries or connection geometries of the elements as well as with respect to the mutual coupling of these elements.

  The device for controlling the medium advantageously has the feature that the valve module is arranged spatially offset in parallel to an axis determined by the outlet of the drive module. In addition to the central axis of the drive mechanism determined by the drive module outlet, the central axis passing through the drive module outlet is vertically projected on the drive module side surface of the valve module casing, and other axes are determined. Yes. The spacing between the two axes determines the deviation between the central axis passing through the outlet and the surface of the valve module casing. The deviation of these elements is advantageous in allowing them to be arranged according to the invention and brought into contact with each other. Furthermore, by increasing the displacement of the elements that are in contact with each other, for example by means of an L-shaped pump module casing or by other elements between them, further functions can be introduced into these elements, for example It is advantageous. As an alternative, it is advantageous if the displacement of the elements that are in contact with each other can be reduced, for example by adapting the valve module into which the drive module is inserted or press-fit, for example by reducing its structural volume. is there.

  In one possible configuration, it is advantageous if at least one compression chamber for each pump element moved by the drive module is provided to allow pump functionality within the pump module. Furthermore, a suction valve / discharge valve is provided in the compression chamber, and a supply pipe / discharge pipe for the medium to be conveyed is provided.

  Advantageously, these elements are integrated directly into the pump module. This can provide a spatially tight attachment of the pump element to the drive module. In addition, this makes it possible to take advantage of the structural volume of the pump module generated at this position by the end face of the drive module being surrounded by the pump module.

  In an advantageous embodiment, the drive module uses at least one electrodynamic drive mechanism. In particular, an electromagnetic drive mechanism is used for this purpose. The electromagnetic drive mechanism has an advantage that an electromagnetic field is generated by application of a voltage. This makes it possible to intentionally switch the drive or cause control. Furthermore, a linear drive mechanism is advantageously provided in order to obtain reduced noise emission and reduced wear.

  The drive module is advantageously configured as a linear drive mechanism with two electromagnetic drive mechanisms. The return of the armature displaced in one direction by the first drive mechanism and the pump element coupled thereto activates the second drive mechanism, and the attached armature and the pump coupled thereto by the drive mechanism. This is done by displacing the element in the direction opposite to the first direction. This advantageously saves auxiliary components (e.g. return springs) and reduces costs and assembly costs. At the same time, the energy consumption for displacing the armature is reduced, for example by eliminating the need for a return spring that has to be additionally tensioned during displacement in order to enable return.

  The drive module of the linear drive mechanism provided in accordance with the invention is advantageously implemented in a cylindrical shape substantially symmetrically so as to have outlets provided to face both end faces. Thus, the drive module does not have the insertion geometry or closure geometry normally provided for the hydraulic device of the ABS / ESP system. This insertion geometry or closure geometry requires a new geometric configuration and placement of the module in the context of the use of a linear drive. This is made possible by the device for controlling the medium according to the invention.

  Further, it is advantageous that the components that are conventionally directly incorporated in the rectangular block of the hydraulic device of the ABS / ESP brake control system have a different arrangement. Furthermore, it is advantageous to connect these components outside rather than incorporating them. For example, a pressure accumulation cartridge connected from the outside to the pump module casing according to the present invention. This is advantageous because the amount of material used can be reduced. Further, since the space is close, the conveyance distance between the pressure accumulation cartridge and the pump module is shortened.

  According to an advantageous embodiment, the drive module is fixed to the valve module via a pump module. In this case, direct coupling between the drive module and the valve module can be omitted. This saves the necessary coupling elements and assembly steps.

  According to a further configuration of the invention, the drive module is coupled to the valve module using a surrounding element. In particular, a hose clamp-like element is provided as a surrounding element, which is connected to the valve module using a fixing element, in particular using a screw. With the surrounding element, the implementation of the drive module without a casing can be applied. In this case, a separate cylindrical casing of the drive module surrounding the magnetic circuit can be omitted. This embodiment is advantageous because heat transfer from the stator and coils to the valve module casing is also improved. Further, advantages and savings in manufacturing are obtained, for example, by eliminating the need for a press-fitting process of the drive casing into the valve casing.

  As already mentioned, according to an advantageous embodiment, the pump module and the valve module are connected by a screw connection, a press connection, a rivet connection and / or a self-clinching connection. For this purpose, a coupling element which is substantially configured in the form of a pin, sleeve or rivet is suitable. An advantageous embodiment of the invention is to implement the coupling element in a substantially sleeve shape. The medium to be conveyed can be guided in a passage inside the sleeve-like coupling element. In order to realize this advantage, the coupling element is positioned in alignment with the positioning of the media tube. For this reason, at least one coupling element is provided as a coupling part between the valve module and the pump module. Alternatively, multiple coupling elements may be used for multiple tubes, for example, one coupling element may be used for each supply and discharge of inhaled and discharged media.

  It is advantageous that the sealing and holding forces can be transmitted by fitting the sleeve-like coupling element into the casing. The screw joint can be omitted. The substantially sleeve-like coupling element is first pushed or pressed into one of the fitting holes of the valve module casing or the pump module casing. Next, the other casing is pushed or press-fitted. Sealability can be caused by oversize of the coupling element outer diameter relative to the hole diameter, or alternatively, a special sealing geometry, such as self-clinching in the coupling element and in the hole. Advantageously, it can be produced by a matched geometry.

  The pushing force for fitting the coupling element into the casing can be transmitted via the tube surface (as the outer diameter surface minus the inner diameter surface of the coupling element) or via a hook provided on the coupling element. It is advantageous if possible. The scissors of the coupling element are advantageous because they provide a second push-in measure. This is because a larger transmission surface is provided by the heel for the indentation force, for example to avoid overload and to prevent malfunctioning deformation of the casing. Furthermore, it is used as a heel stopper and is used to adjust the indentation depth.

  In a further advantageous configuration of the invention, the alignment of the stator elements of the electromagnetic drive mechanism and the alignment of the stator coils with windings are performed via the end plates of the stator. The binding is then provided via two covers, which are connected to each other using screws and nuts, thereby fixing the stator coil. The interval between the center points of the two stator coils is determined via the interval setting center element of the stator. The stator element may be composed of one or more stator segments.

  Advantageously, the electrical contacts of the drive module are guided through the casing of the valve module and the casing of the pump module. This allows a short path for electrical contact, thus allowing for example a smaller resistance. In addition, this also allows protection of the tube.

  The invention further relates to a device for controlling a medium comprising a valve module, a pump module and a drive module as a pump system device for a hydraulic device of an ABS / ESP system as an advantageous arrangement.

  Next, the present invention will be described in detail with reference to the drawings and embodiments, but this does not limit the present invention.

FIG. FIG. 3 is a longitudinal sectional view of a drive module including two drive mechanisms and an armature and a piston that move to act on the pump module. FIG. 2 is a side view of an embodiment of a control device, also showing a sleeve-like self-clinching coupling element for guiding fluid. 1 is an illustration of one embodiment of a sleeve-like self-clinching coupling element. FIG.

  FIG. 1 shows an embodiment of an arrangement configuration of a pump module 101, a drive module 103, and a valve module 105 as constituent elements.

  The drive module 101 has at least one drive mechanism 116 configured as an electromagnetic drive mechanism 116. For this reason, the electrical contact part 120 is provided.

  The drive mechanism 116 is configured in a cylindrical shape. Similarly, the casing 104 of the drive module 103 has a cylindrical shape.

  The end face 117 of the drive module 103 has an outlet 107. The outlet 107 is provided in alignment with at least one drive mechanism 116 of the drive module 103. A central outlet 107 is provided for the end face 117. Two outlets 107 of one drive module 103 determine a central axis 109 of the drive module 103.

  The outlet 107 allows interaction between the drive module 103 and the pump module 101 via the pump element 108. The pump element 108 is driven by an electromagnetic drive mechanism 116. The pump element 108 is configured as a reciprocating piston. The pump element 108 acts in the compression chamber 110 of the pump module 101.

  As the pump element 108 enters the compression chamber 110, the medium 115, eg, fluid, therein is compressed. By using the supply pipe 113, the suction valve 111, the discharge valve 112, and the discharge pipe 114, which are auxiliary elements, the medium 115 can be conveyed. These elements are incorporated in the pump module 101.

  The medium to be conveyed can be supplied from the outside by the valve 401 (FIG. 4) of the valve module 105, or can be supplied from an internal reservoir. An internal storage for this type of medium is illustrated as being configured as a pressure chamber 119 in FIG. The pressurizing chamber 119 is incorporated in the pump casing 102. In particular, a unique pressurizing chamber 119 is provided for each pump module 101.

  Both pump modules 101 (of which only one is shown in FIG. 1) are incorporated in one common casing 102. The casing is U-shaped and is shown transparently. The U-shaped pump casing 102 includes a drive module 103 in part. The outlet 107 of the drive module 103 on the facing end faces 117 is completely surrounded.

  Next to the central axis 109 of the drive mechanism 116 determined by the outlet 107 of the drive module 103, another axis 121 is shown in FIG. The axis 121 is a projection of the axis 109 perpendicularly to the surface 118 of the valve module casing 106 on the drive module 103 side. Further, a deviation 122 between the axis 109 and the projection axis 121 is shown.

  FIG. 2 shows an alternative embodiment of the control device. Both pump modules 101 are arranged in separate casings 202. Both casings 202 each have an L shape. Basically, reference is made to the above description for the embodiment of FIG.

  Each L-shaped pump casing 202 surrounds one of the outlets 107 of the drive module 103. Furthermore, it will be appreciated that it is not necessary to completely surround the end face 117 of the drive module 103.

  The pump element 108 acting on the compression chamber 110 through the outlet 107 generates a pressing force on the pump casing 202 in the direction of the central axis 109 of the drive mechanism 116. Since the pump casing 202 is divided into two parts, the coupling portion 203 is used to absorb the pressing force that acts. The pressing force is converted through a screw.

  FIG. 2 further illustrates an alternative embodiment for intermediate storage of media 115. The intermediate storage is performed via a pressurizing chamber 201 that is outside and connected to the pump casing 102. In particular, a unique pressurizing chamber 201 is provided for each pump module 101.

  FIG. 3 shows another alternative embodiment of the control device. Please refer to the above description for the embodiment of FIGS. 1 and 2 anew. The basic difference is that each pump module 101 is incorporated in a separate block casing 302.

  The block-shaped casing 302 partially surrounds the drive module casing 104 and the region of the end surface 117 of the drive module 103. In this case, the outlet 107 of the drive module 103 is completely surrounded by the pump casing 302.

  The block-shaped casing 302 is coupled to the valve module casing 106 via the fixed portion 301. These fixing parts 301 are preferably removable screw connections. The structural coupling between the drive module 103 and the valve module 105 is performed by press-fitting the drive module casing 104 into the valve module casing 106.

  Operational coupling proceeds via the pump element 108 coupled to the armature carrier 804 and driven by the drive mechanism 116. These pump elements act on both sides (each with one pump element on one side) in the compression chamber 110, thereby conveying the medium 115 supplied via the valve 401 and being distributed via the valve module 105. , Discharged through valve 402.

  FIG. 4 is a side view of an embodiment of a control device including a valve module and a pump module that are illustrated transparently in a block-like casing. Please refer to the above description for the embodiments of the previous drawings.

  Here, it can be seen clearly that a part of the drive module casing 104 sinks into the valve module casing 106, which can advantageously reduce the structural volume of the system.

  The permeation side view further shows the path of the fluid sucked by the transport mechanism of the pump module 101. The fluid can be supplied from the outside by the valve 401 or can be taken out from the internal intermediate reservoir, for example, the pressurizing chamber 119. The fluid is introduced into the compression chamber 110 through the supply pipe 113 and the suction valve 111.

  A packing 403 is provided at a fluid transition portion from the valve module casing 106 to the pump module casing 302 connected by the screw coupling portion 301. A packing 403 is shown for both the supply pipe 113 and the discharge pipe 114.

  FIG. 5 is a side view of an embodiment of a control device including a valve module and a pump module that are illustrated transparently in a block-like casing. Please refer to the description of the embodiment of the previous drawings.

  The permeation side view further shows the path of the fluid pushed out by the transport mechanism of the pump module 101. The fluid is discharged from the compression chamber 110 through the discharge valve 112, the discharge pipe 114, and the valve 402.

  FIG. 6 is a perspective view of an alternative embodiment of a control device comprising a pressurization chamber 201 connected to a casing. Please refer to the above description for the embodiments of the previous figures.

  In this case, the external pressurizing chamber 201 is connected to the casing 102 of the pump module 101 from the outside. One pressurizing chamber 201 is provided for each pump module 101.

  FIG. 7 is a side view of an alternative embodiment of a control device comprising a valve module 105 and a pump module 101 shown transparently in a block-like casing 302. Please refer to the above description for the embodiments of the previous drawings.

  Here, unlike the above description, the electromagnetic drive mechanism 116 is implemented without a casing. Therefore, there is no casing around the magnetic circuit of the drive mechanism. The drive module 103 provided with the drive mechanism 116 is fixed to the pump casing 102 using a hose clamp-like auxiliary element 701 and a fixing element 702.

  FIG. 8 is a longitudinal cross-sectional view of the drive module 103 and the pump element 108 that is moved by the drive mechanism 116 and coupled to the armature carrier 804.

  FIG. 8 shows an embodiment provided with two drive mechanisms 116, an armature carrier 804 to be moved, and an armature 805 coupled thereto. The armature carrier 804 is coupled to the pump element 108, which is configured as a reciprocating piston and acts in the compression chamber 110 of the pump module 101.

  Each of the drive mechanisms 116 includes a stator element 806 and stator coils 807 and 808. By electrical switching, switching can be performed between the stator coil 808 that has been activated and the stator coil 807 that has not been activated. In the starting circuit, a magnetic flux is generated along the main magnetic field lines 809. The magnetic field generated in this way acts on the active ferromagnetic portion of the attached armature 805 and pulls it to the position where the magnetoresistance is the smallest.

  By alternately activating the stator coils 807 and 808 of the drive mechanism 116, the armature carrier 804 coupled to both armatures 805 or the pump element 108 coupled thereto is caused to undergo reversible vibration reciprocating motion.

  The widths of the stator element 806 and the armature 805 are aligned with each other with respect to the growth of the magnetic flux 809 and are substantially the same in this embodiment. In order to enable reciprocal movement in the opposite direction when one stator coil 808 is activated each time, a different interval is defined for the center point of both stator coils 807 and 808 compared to the center point of the armature 805. ing. The distance between the center points of the stator coils 807 and 808 is defined via a stator distance setting center element 802. The distance between the center points of both armatures 805 is defined via the armature spacing center element 803. The stator element 806 is centered via a stator end plate 801. In this embodiment, the cohesiveness is provided via two coupling elements 810 that are coupled and secured together using screws 815 and nuts 816.

  In addition, an element for supporting and sealing the armature carrier 804 or pump element 108 is provided. This includes a guide ring 811, a support ring 812, a spacing element 813, and a seal ring 814.

  FIG. 9 is a side view of one embodiment of the control device illustrating the self-clinching joint 901 of both the valve module and pump module casings 106,302. Please refer to the above description for the embodiment of FIGS.

  Here, it is recognized that the pump module casing 302 and the valve module casing 106 are fixed to each other by the screw coupling portion 301 in the previous drawings, whereas FIG. The element 901 is press-fitted. The screw coupling portion 301 can be omitted.

  In this case, the coupling element 901 is implemented in a substantially sleeve shape. This can guide the medium 115 to be sucked or pushed into the inner passage 902 of the coupling element 901. In order to take advantage of this advantage, the coupling element 901 is positioned in alignment with the positioning of the supply and discharge tubes 113, 114.

  FIG. 10 illustrates an embodiment of a self-clinching joint with a fluid guide. In particular, please refer to the embodiment of FIG. In this case, the coupling element 901 has a structured surface 1002 that assists in clamping and sealing the joint during press fitting. Thus, the self-clinching joint of the coupling element 901 serves to maintain the holding force, thereby allowing tight coupling of the elements to be coupled.

  The flange 1001 of the coupling element 901 is used as a stopper and is used for adjusting the press-fitting depth. In addition to the tube surface 1003, the flange surface 1004 is simultaneously used as a stop surface during the press-fitting process.
