Description

Steuerungsmodul eines Fahrzeugs Control module of a vehicle
Beschreibung description
Die Erfindung betrifft ein Steuerungsmodul eines Fahrzeugs, mit mehreren elektrome chanischen Funktionselementen, die auf einer Trägerplatte angeordnet sowie mittels Klemmelemente form- und kraftschlüssig an der Trägerplatte fixiert sind, wobei die Klemmelemente an einer Druckplatte ausgebildet sind, welche an Abstandshaltern der T rägerplatte befestigt ist. The invention relates to a control module of a vehicle, with several electromechanical functional elements, which are arranged on a carrier plate and fixed positively and non-positively to the carrier plate by means of clamping elements, the clamping elements being formed on a pressure plate which is attached to spacers of the carrier plate.
Elektromechanische Funktionselemente, wie zum Beispiel Magnetventile, Druck- und Temperatursensoren einer Getriebesteuerung, werden bevorzugt in einem Steue rungsmodul zusammengefasst, da sie dort einfacher montierbar sind und leichter ge gen schädliche Einflüsse durch Spritzwasser und Öl sowie gegen eine mechanische Beschädigung geschützt werden können. Electromechanical functional elements, such as solenoid valves, pressure and temperature sensors of a transmission control, are preferably combined in a control module, as they are easier to assemble there and can be more easily protected against harmful influences from splash water and oil as well as against mechanical damage.
Um eine aufwendige Befestigung jedes einzelnen Funktionselementes mit beispiels weise zwei Schrauben oder zwei Rastnasen in dem Steuerungsmodul zu vermeiden, wurde in der DE 10 2017002 357 A1 eine Befestigungsanordnung zur Befestigung mehrerer elektromechanischer Funktionselemente in einem Steuerungsmodul vorge schlagen, bei der die Funktionselemente auf einer Trägerplatte angeordnet und mittels Klemmelemente einer an Abstandshaltern der Trägerplatte befestigten Druckplatte form- und kraftschlüssig an der Trägerplatte fixiert sind. Diese Klemmelemente sind als ebene Zentrierbereiche der Druckplatte ausgebildet, welche an die Kontur der oberen Außenwand der Funktionselemente angepasst und von plastisch verformbaren Ran delementen umgeben sind. In einer ersten Ausführungsform dieser Befestigungsanord nung sind die verformbaren Randelemente durch Stege gebildet, die nach dem Aus stanzen von schlitzförmigen Öffnungen am Rand der Zentrierbereiche stehengelassen wurden. In einer zweiten Ausführungsform dieser Befestigungsanordnung sind die ver formbaren Randelemente durch jeweils einen umlaufenden Materialabtrag am Rand der Zentrierbereiche gebildet. Die Flöhe der Abstandshalter ist geringer als die Bauhöhe der Funktionselemente, so dass die verformbaren Randelemente bei der Montage der Druckplatte an den Abstandshaltern der Trägerplatte beim Andrücken an die oberen Außenwände der zugeordneten Funktionselemente plastisch und elastisch verformt werden. In order to avoid complex fastening of each individual functional element with, for example, two screws or two locking lugs in the control module, a fastening arrangement for fastening several electromechanical functional elements in a control module was proposed in DE 10 2017 002 357 A1, in which the functional elements are arranged on a carrier plate and by means of clamping elements of a pressure plate fastened to spacers of the carrier plate are fixed positively and non-positively to the carrier plate. These clamping elements are designed as flat centering areas of the pressure plate, which are adapted to the contour of the upper outer wall of the functional elements and are surrounded by plastically deformable Ran del elements. In a first embodiment of this fastening arrangement, the deformable edge elements are formed by webs that were left to stand after punching out slot-shaped openings on the edge of the centering areas. In a second embodiment of this fastening arrangement, the ver formable edge elements are each formed by a circumferential material removal at the edge of the centering areas. The fleas of the spacers is less than the overall height of the functional elements, so that the deformable edge elements are plastically and elastically deformed when the pressure plate is mounted on the spacers of the carrier plate when pressed against the upper outer walls of the associated functional elements.
Nachteilig ist an einer derartigen Befestigungsanordnung, dass die Zentrierbereiche innerhalb der Druckplatte genau positioniert sein müssen, um eine problemlose Monta ge zu gewährleisten und eine Beschädigung einzelner Funktionselemente zu vermei den. Zudem setzt diese Befestigungsanordnung eine weitgehend gleiche Bauhöhe aller Funktionselemente voraus, da die rissfreie Verformbarkeit der Randelemente begrenzt ist. The disadvantage of such a fastening arrangement is that the centering areas must be precisely positioned within the pressure plate in order to ensure problem-free installation and to avoid damage to individual functional elements. In addition, this fastening arrangement requires that all functional elements have largely the same overall height, since the crack-free deformability of the edge elements is limited.
Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, ein Steuerungsmodul ei nes Fahrzeugs der eingangs genannten Bauart vorzustellen, dessen Klemmelemente mit größerer Toleranz an der Druckplatte ausgebildet werden können, und mit denen Funktionselemente mit unterschiedlichen Bauhöhen an der Trägerplatte fixierbar sind. The present invention was therefore based on the object of presenting a control module egg nes vehicle of the type mentioned, the clamping elements of which can be formed with greater tolerance on the pressure plate, and with which functional elements with different heights can be fixed on the carrier plate.
Diese Aufgabe ist in Verbindung mit den Merkmalen des Oberbegriffs des Anspruchs 1 dadurch gelöst, dass die Abstandshalter eine geringfügig größere Flöhe als die Bauhö he des höchsten Funktionselementes aufweisen, und dass die Druckplatte für jedes der Funktionselemente mit mindestens einem als eine Klemmlasche ausgebildeten Klem melement versehen ist, wobei die Klemmlaschen jeweils an einer durch dieselben teil weise geschlossenen Öffnung der Druckplatte angeordnet sowie in Richtung zu der Trägerplatte abgewinkelt ausgebildet sind. This object is achieved in connection with the features of the preamble of claim 1 in that the spacers have a slightly larger height than the height of the highest functional element, and that the pressure plate for each of the functional elements is provided with at least one clamping element designed as a clamping lug is, wherein the clamping tabs are each arranged on an opening of the pressure plate which is partially closed by the same and are angled in the direction of the carrier plate.
Vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Steue rungsmoduls sind Gegenstand der abhängigen Patentansprüche. Advantageous refinements and developments of the control module according to the invention are the subject of the dependent claims.
Die Erfindung betrifft demnach ein Steuerungsmodul eines Fahrzeugs mit mehreren elektromechanischen Funktionselementen. Die Funktionselemente, bei denen es sich um Magnetventile sowie Druck- und Temperatursensoren handeln kann, sind auf einer Trägerplatte angeordnet und mittels Klemmelemente einer an Abstandshaltern der Trä gerplatte befestigten Druckplatte form- und kraftschlüssig an der Trägerplatte fixiert. The invention accordingly relates to a control module of a vehicle with a plurality of electromechanical functional elements. The functional elements, which can be solenoid valves as well as pressure and temperature sensors, are on one Arranged carrier plate and fixed by means of clamping elements of a pressure plate attached to spacers of the Trä gerplatte form and force fit on the carrier plate.
Durch die Ausbildung der Klemmelemente als jeweils an einer durch dieselben teilwei se geschlossenen Öffnung der Druckplatte angeordnete und in Richtung zu der Trä gerplatte abgewinkelte Klemmlaschen drücken diese nach der Montage der Druckplatte aufgrund der geringfügig größeren Höhe der Abstandshalter mit ihrer unteren Außen kante auf die obere Außenwand des jeweiligen Funktionselementes, wobei die Klemm laschen plastisch und/oder elastisch verformt werden. Somit ist für die Fixierung der Funktionselemente an der Trägerplatte keine genaue Positionierung der Klemmlaschen an der Druckplatte erforderlich. Zudem können die Klemmlaschen in geeigneter Weise auf unterschiedliche Bauhöhen der Funktionselemente angepasst werden. Due to the formation of the clamping elements as each arranged on a partially closed opening of the pressure plate by the same and angled towards the Trä gerplatte clamping tabs press this after mounting the pressure plate due to the slightly greater height of the spacers with their lower outer edge on the upper outer wall of the respective functional element, the clamping tabs being plastically and / or elastically deformed. Thus, no precise positioning of the clamping straps on the pressure plate is required for the fixation of the functional elements on the carrier plate. In addition, the clamping lugs can be adapted in a suitable manner to different structural heights of the functional elements.
Um die Stabilität und die Zuverlässigkeit der Fixierung der Funktionselemente an der Trägerplatte zu erhöhen, ist die Druckplatte zumindest für eines der Funktionselemente bevorzugt mit zwei Klemmlaschen versehen, welche spiegelsymmetrisch zu einer ge ometrischen Mittelachse des betreffenden Funktionselementes mit ihren freien Enden aufeinander zu gerichtet an jeweils einer durch dieselben teilweise geschlossenen Öff nung der Druckplatte angeordnet sind. In order to increase the stability and the reliability of the fixation of the functional elements on the carrier plate, the pressure plate is preferably provided with two clamping straps for at least one of the functional elements, which are mirror-symmetrical to a geometric central axis of the functional element in question with their free ends directed towards one another at one each are arranged through the same partially closed Publ opening of the pressure plate.
Gemäß einer dazu alternativen zweiten Ausführungsform kann vorgesehen sein, dass die Druckplatte zumindest für eines der Funktionselemente mit zwei Klemmlaschen versehen ist, welche spiegelsymmetrisch zu einer geometrischen Mittelachse des be treffenden Funktionselementes mit ihren freien Enden aufeinander zu gerichtet an der selben durch diese teilweise geschlossenen Öffnung der Druckplatte angeordnet sind. According to an alternative second embodiment, it can be provided that the pressure plate is provided with two clamping straps for at least one of the functional elements, which are mirror-symmetrical to a geometric central axis of the relevant functional element with their free ends directed towards each other at the same opening of the partially closed Pressure plate are arranged.
Eine dritte Ausführungsform sieht vor, dass die Druckplatte zumindest für eines der Funktionselemente mit zwei Klemmlaschen versehen ist, welche punktsymmetrisch zu einer geometrischen Mittelachse des betreffenden Funktionselementes zueinander ausgerichtet an jeweils einer durch dieselben teilweise geschlossenen Öffnung der Druckplatte angeordnet sind. Eine vierte mögliche Ausführungsform sieht vor, dass die Druckplatte zumindest für eines der Funktionselemente mit zwei Klemmlaschen versehen ist, welche punktsym metrisch zu einer geometrischen Mittelachse des betreffenden Funktionselementes parallel zueinander ausgerichtet an derselben durch diese teilweise geschlossenen Öffnung der Druckplatte angeordnet sind. A third embodiment provides that the pressure plate is provided with two clamping straps for at least one of the functional elements, which are arranged point-symmetrically to a geometric central axis of the functional element in question, aligned with one another, at an opening in the pressure plate that is partially closed by the same. A fourth possible embodiment provides that the pressure plate is provided with two clamping straps for at least one of the functional elements, which are arranged point-symmetrically to a geometric central axis of the functional element in question, aligned parallel to one another, on the same through this partially closed opening of the pressure plate.
Die Klemmlaschen können auf einfache Weise derart an unterschiedliche Bauhöhen der Funktionselemente angepasst werden, dass die Klemmlaschen für die Funktions elemente mit einer größeren Bauhöhe länger ausgebildet und weiter abgewinkelt sind als die Klemmlaschen für die Funktionselemente mit einer geringeren Bauhöhe. Zudem kann mittels der Klemmlaschen eine gegebenenfalls variierende Bauhöhentoleranz oder Einbauhöhentoleranz der Funktionselemente nach deren Montage klemmkraftbe zogen kompensiert werden. In alle genannten Fällen wird wenigstens eine definierte Mindestklemmkraft durch die Klemmelemente auf die Funktionselemente ausgeübt. The clamping lugs can be easily adapted to different heights of the functional elements in such a way that the clamping lugs for the functional elements with a greater overall height are longer and more angled than the clamping lugs for the functional elements with a lower overall height. In addition, the clamping straps can be used to compensate for a possibly varying overall height tolerance or installation height tolerance of the functional elements after they have been installed with regard to clamping force. In all of the cases mentioned, at least a defined minimum clamping force is exerted on the functional elements by the clamping elements.
Die Druckplatte kann aus einem Metallblech bestehen. Die Klemmlaschen sind dann jeweils derart dreiseitig aus dem Metallblech freigestanzt und so weit in Richtung zu der Trägerplatte umgebogen, dass diese bei der Befestigung der Druckplatte an den Ab standshaltern der Trägerplatte beim Andrücken an die oberen Außenwände der zuge ordneten Funktionselemente plastisch und/oder nur elastisch verformt werden. Durch diese Verformung der Klemmlaschen verbleibt durch deren elastische Spannung eine definierte Anpresskraft auf die oberen Außenwände der Funktionselemente. Eine ge naue Ausführung der Abwinkelung der Klemmlaschen ist somit in diesem Fall nicht er forderlich und es kann auch die angesprochene variierende Flöhentoleranz klemmkraft bezogen kompensiert werden. The pressure plate can consist of a metal sheet. The clamping lugs are then punched out of the sheet metal on three sides and bent so far in the direction of the carrier plate that they are plastic and / or only elastic when the pressure plate is fastened to the carrier plate when it is pressed against the upper outer walls of the assigned functional elements be deformed. As a result of this deformation of the clamping lugs, a defined contact force remains on the upper outer walls of the functional elements due to their elastic tension. A precise execution of the angling of the clamping lugs is therefore not necessary in this case and the mentioned varying surface tolerance can also be compensated for in relation to the clamping force.
Die Druckplatte kann aber auch aus einer Kunststoffscheibe oder Kunststoffplatte be stehen. Die Klemmlaschen sind dann jeweils an den Rand einer Öffnung in der Druck platte derart abgewinkelt angeformt, dass diese bei der Befestigung der Druckplatte an den Abstandshaltern der Trägerplatte beim Andrücken an die oberen Außenwände der zugeordneten Funktionselemente nur elastisch verformt werden. Da Kunststoffe zu mindest im kalten Zustand nicht zerstörungsfrei plastisch verformt werden können, ist in diesem Fall eine relativ genaue Ausführung der Abwinkelung der Klemmlaschen erfor derlich. The pressure plate can also be made of a plastic disc or plastic plate. The clamping tabs are then each angled at the edge of an opening in the pressure plate so that they are only elastically deformed when the pressure plate is attached to the spacers of the carrier plate when pressed against the upper outer walls of the associated functional elements. Since plastics cannot be plastically deformed in a non-destructive manner, at least when they are cold, in In this case, a relatively precise execution of the angling of the clamping lugs is neces sary.

Fig. 5 eine Darstellung wie in Fig. 4, jedoch mit zwei punktsymmetrisch sowie paral lel zueinander angeordneten Klemmlaschen, welche an einer Öffnung in der Druck platte angeordnet sind. Fig. 5 shows a representation as in Fig. 4, but with two point-symmetrically and paral lel to each other arranged clamping tabs, which are arranged at an opening in the pressure plate.
Ein in der perspektivischen Ansicht von Fig. 1 abgebildetes Steuerungsmodul 2 umfasst eine Trägerplatte 4 mit mehreren pfostenförmig nach oben gerichteten Abstandshaltern 6, mehrere auf der Trägerplatte 4 angeordnete elektromechanische Funktionselemente 8, bei denen es sich vorliegend beispielhaft um Magnetventile handelt, und eine Druck platte 14, die auf die Abstandshalter 6 und die Funktionselemente 8 aufgesetzt sowie mittels mehrerer Schrauben 26 an den Abstandshaltern 6 befestigt ist. A control module 2 shown in the perspective view of FIG. 1 comprises a carrier plate 4 with several post-shaped spacers 6 directed upwards, several electromechanical functional elements 8 arranged on the carrier plate 4, which are in the present case, for example, solenoid valves, and a pressure plate 14 , which is placed on the spacers 6 and the functional elements 8 and fastened to the spacers 6 by means of several screws 26.
In der Schnittansicht von Fig. 2a und dem in Fig. 3a abgebildeten vergrößerten Aus schnitt B aus Fig. 2a ist die Druckplatte 14 in der Schnittebene A - A gemäß Fig. 1 im nicht montierten Zustand abgebildet. In der Schnittansicht von Fig. 2b und dem in Fig. 3b abgebildeten vergrößerten Ausschnitt C aus Fig. 2b sind die Trägerplatte 4, die Funktionselemente 8 und die Druckplatte 14 in der Schnittebene A - A gemäß Fig. 1 im montierten Zustand abgebildet. In the sectional view of FIG. 2a and the enlarged section B from FIG. 2a shown in FIG. 3a, the pressure plate 14 is in the sectional plane AA according to FIG. 1 in not shown in assembled condition. In the sectional view of FIG. 2b and the enlarged section C from FIG. 2b shown in FIG. 3b, the carrier plate 4, the functional elements 8 and the pressure plate 14 are shown in the sectional plane AA according to FIG. 1 in the assembled state.
Die Druckplatte 14 besteht vorliegend aus einem Metallblech und weist für jede der Schrauben 26 eine Bohrung 16 auf. Die Bauhöhe HB der Funktionselemente 8 ist vor liegend beispielhaft bei allen Funktionselementen 8 gleich, sie könnte jedoch auch un terschiedlich groß sein. Die Abstandshalter 6 weisen eine geringfügig größere Flöhe Fl als die Bauhöhe HB der Funktionselemente 8 auf. Zur form- und kraftschlüssigen Fixie rung der Funktionselemente 8 an der Trägerplatte 4 ist die Druckplatte 4 für jedes der Funktionselemente 8 mit zwei als Klemmlaschen ausgebildeten Klemmelementen 20, 20’ versehen. In the present case, the pressure plate 14 consists of a metal sheet and has a bore 16 for each of the screws 26. The overall height HB of the functional elements 8 is the same for all functional elements 8, but it could also be of different sizes. The spacers 6 have a slightly larger fleas Fl than the overall height HB of the functional elements 8. For positive and non-positive fixation of the functional elements 8 on the carrier plate 4, the pressure plate 4 for each of the functional elements 8 is provided with two clamping elements 20, 20 'designed as clamping lugs.
Die Klemmlaschen 20, 20’ sind jeweils durch eine dreiseitige Freistanzung in einer durch die Klemmlaschen 20, 20’ teilweise geschlossenen Öffnung 18, 18’ der Druck platte 14 angeordnet und in Richtung zu der Trägerplatte 4 umgebogen. Die für jedes Funktionselement 8 vorgesehenen zwei Klemmlaschen 20, 20’ sind jeweils spiegel symmetrisch zu der geometrischen Mittelachse 10 des zugeordneten Funktionselemen tes 8 mit ihren freien Enden 22 aufeinander zu gerichtet an den jeweiligen Öffnungen 18, 18’ der Druckplatte 14 angeordnet. Die an jeweils einer Öffnung 18, 18’ angeordne ten Klemmlaschen 20, 20’ können auch punktsymmetrisch und parallel zueinander ausgerichtet sein, ähnlich wie diese Ausrichtung die Fig. 5 zeigt. Die Klemmlaschen 20, 20’ sind so weit in Richtung zu der Trägerplatte 4 umgebogen, dass diese bei der Be festigung der Druckplatte 14 an den Abstandshaltern 6 der Trägerplatte 4 beim Andrü cken derer jeweiligen Außenkante 24 an die oberen Außenwände 12 der Funktions elemente 8 plastisch und/oder nur elastisch verformt werden. The clamping tabs 20, 20 'are each arranged by a three-sided free punch in an opening 18, 18' of the pressure plate 14 partially closed by the clamping tabs 20, 20 'and are bent over in the direction of the carrier plate 4. The two clamping lugs 20, 20 'provided for each functional element 8 are each arranged mirror-symmetrically to the geometric center axis 10 of the associated functional element 8 with their free ends 22 facing one another at the respective openings 18, 18' of the pressure plate 14. The clamping lugs 20, 20 'arranged at one opening 18, 18' can also be aligned point-symmetrically and parallel to one another, similar to how this alignment is shown in FIG. 5. The clamping tabs 20, 20 'are bent so far in the direction of the carrier plate 4 that they plastically when the pressure plate 14 is fastened to the spacers 6 of the carrier plate 4 when their respective outer edges 24 are pressed against the upper outer walls 12 of the functional elements 8 and / or are only elastically deformed.
Durch die plastische Verformung der Klemmlaschen 20, 20’ verbleibt durch deren elas tische Spannung eine definierte Anpresskraft auf die oberen Außenwände 12 der Funk tionselemente 8. Eine genaue Ausführung der Abwinkelung der Klemmlaschen 20, 20’ ist somit nicht erforderlich. Zudem müssen die Öffnungen 18, 18’ mit den Klemmla- sehen 20, 20’ für die Fixierung der Funktionselemente 8 innerhalb der Druckplatte 14 nicht exakt positioniert werden. As a result of the plastic deformation of the clamping lugs 20, 20 ', their elastic tension leaves a defined contact force on the upper outer walls 12 of the functional elements 8. A precise execution of the angling of the clamping lugs 20, 20' is therefore not required. In addition, the openings 18, 18 'must be see 20, 20 'for the fixation of the functional elements 8 within the pressure plate 14 are not exactly positioned.
Die Fig. 4 zeigt ausschnittweise eine schematische Draufsicht auf eine Druckplatte 14 ähnlich der Druckplatte gemäß Fig. 1 . Zu erkennen ist eine Öffnung 18” in der Druck platte 14, welche durch zwei Klemmlaschen 21 a, 21 b teilweise verschlossen ist. Diese Klemmlaschen 21 a, 21 b sind einstückig mit dem Material der Druckplatte 14 verbunden und in Richtung zu einem vergleichsweise durchmesserkleinen Funktionselement 8 umgebogen. Flierdurch üben die beiden Klemmlaschen 21a, 21 b eine definierte Klemmkraft auf die Außenwand 12 des Funktionselements 8 aus, welche das Funkti onselement 8 sicher in seiner vorbestimmten Position hält. Die Besonderheit dieser Ausführungsform gemäß Fig. 4 besteht darin, dass die beiden auf das gleiche Funkti onselement 8 einwirkenden Klemmlaschen 21a, 21 b spiegelsymmetrisch zu der geo metrischen Mittelachse 10 des Funktionselementes 8 sowie mit ihren freien Enden 22 aufeinander zu gerichtet an derselben Öffnung 18” der Druckplatte 14 angeordnet sind. FIG. 4 shows a detail of a schematic top view of a pressure plate 14 similar to the pressure plate according to FIG. 1. An opening 18 ″ in the pressure plate 14, which is partially closed by two clamping tabs 21 a, 21 b, can be seen. These clamping lugs 21 a, 21 b are integrally connected to the material of the pressure plate 14 and are bent over in the direction of a functional element 8 with a comparatively small diameter. Flierby exert the two clamping tabs 21a, 21b from a defined clamping force on the outer wall 12 of the functional element 8, which holds the functi onselement 8 securely in its predetermined position. The peculiarity of this embodiment according to FIG. 4 is that the two clamping lugs 21a, 21b acting on the same function element 8 are mirror-symmetrical to the geometric center axis 10 of the function element 8 and with their free ends 22 directed towards each other at the same opening 18 " the pressure plate 14 are arranged.
Die Ausbildung beziehungsweise Anordnung von zwei Klemmlaschen 21c, 21 d an der selben Öffnung 18” der Druckplatte 14 ist auch bei einer weiteren Ausführungsform realisiert, welche in Fig. 5 dargestellt ist. Hierbei ist vorgesehen, dass die Druckplatte 14 für das der Öffnung 18” zugeordnete, vergleichsweise durchmesserkleine Funkti onselement 8 mit zwei Klemmlaschen 21 c, 21 d versehen ist, welche punktsymmetrisch zu der geometrischen Mittelachse 10 des Funktionselementes 8 und parallel zueinan der ausgerichtet an derselben Öffnung 18” der Druckplatte 14 angeordnet sind. The formation or arrangement of two clamping lugs 21c, 21d at the same opening 18 ″ of the pressure plate 14 is also implemented in a further embodiment, which is shown in FIG. 5. It is provided here that the pressure plate 14 for the comparatively small-diameter functional element 8 assigned to the opening 18 ″ is provided with two clamping lugs 21c, 21d, which are point-symmetrical to the geometric center axis 10 of the functional element 8 and aligned parallel to one another at the same opening 18 ″ of the pressure plate 14 are arranged.
Die beiden Ausführungsformen gemäß den Figuren 4 und 5 sind dort besonders gut anwendbar, wo vergleichsweise durchmesserkleine Funktionselemente 8 mittels der Klemmlaschen der Druckplatte 14 fixiert werden sollen. Bezugszeichenliste (Teil der Beschreibung) The two embodiments according to FIGS. 4 and 5 can be used particularly well where comparatively small-diameter functional elements 8 are to be fixed by means of the clamping lugs of the pressure plate 14.
