Abstract

The proposal is for a device designed to accomodate an electric motor. The electric motor has a tubular housing section surrounding the motor armature which is arranged substantially concentrically beside and at a distance from the inner wall of a cup of a cup-shaped receptacle belonging to the device. At least three strip-shaped supports held on the cup wall, extending parallel to the motor axis and consisting of an elastic material, project into the receptacle to an extent which is greater than the distance between the tubular housing section and the inner cup wall of the receptacle and with an elastic seal which closes the gap between the inner cup wall of the support and the tubular housing section of the electric motor. A simple and reliable motor arrangement in the receptacle which is easy to assemble is obtained if the seal takes the form of a strip and interconnects the neighbouring supports, thus providing an annular, one-piece component.

Stand der TechnikState of the art
Die Erfindung geht aus von einer Vorrichtung nach der Gattung des Hauptanspruchs. Es ist schon eine Vorrichtung im Handel, bei der die Abstützelemente lose angeliefert und einzeln in Halterungen des Motoraufnah etopfes eingesetzt werden müssen. Nach Einbringen des Elektromotors in die Aufnahme muß in einem weiteren Arbeitsgang dann ein Dichtring in einen Spalt eingebracht werden, der dann zwischen der inneren Topfwand und dem dieser benachbarten, rohrformigen Ge¬ häuseabschnitt des Elektromotors vorhanden ist. Dies ist erforder¬ lich, damit durch den Elektromotor zu leitende Kühlluft nicht durch den Kingspalt entweichen kann und durch den Motor gezwungen wird.The invention relates to a device according to the preamble of the main claim. It is already a device on the market, in which the support elements are delivered loose and must be used individually in holders of the motor mounting pot. After the electric motor has been introduced into the receptacle, a sealing ring must then be introduced into a gap in a further operation, which is then present between the inner pot wall and the tubular housing section of the electric motor adjacent to it. This is necessary so that cooling air to be conducted by the electric motor cannot escape through the king gap and is forced by the motor.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung darge¬ stellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 einen Längsschnitt durch eine teilweise dargestellte Motoraufn hme, in welche strichpunktiert ein Elektromotor sowie ein Abstützelemente und Dichtelemente aufweisendes Bauteil eingezeichnet ist, Figur 2 eine Draufsicht auf die Motoraufnahme gemäß Figur 1, Figur 3 einen Längsschnitt durch das Bauteil gemäß Figur 1, Figur 4 eine Unteransicht des Bauteils gemäß Figur 3 und Figur 5 eine Drauf¬ sicht auf das Bauteil gemäß Figur 3.An embodiment of the invention is shown in the drawing and explained in more detail in the following description. 1 shows a longitudinal section through a partially shown motor mount, in which an electric motor and a component having support elements and sealing elements are shown in broken lines, FIG. 2 shows a plan view of the motor mount according to FIG. 1, FIG. 3 shows a longitudinal section through the component according to FIG. 1, FIG. 4 shows a bottom view of the component according to FIG. 3 and FIG. 5 shows a top view of the component according to FIG. 3.
Beschreibung des AusführungsbeispielsDescription of the embodiment
Figur 1 zeigt eine topff rmige Aufnahme 10 für einen strichpunktiert dargestellten Elektromotor 12. Die topff rmige Aufnahme 10 weist nahe dem Topfrand 14 eine flanschartige Verbreiterung 16 auf, über die die topfformige Aufnahme 10 mit nicht dargestellten Wandteilen, beispielsweise von Führungsschächten für die dem Fahrgastraum eines Kraftfahrzeuges zuzuführende, klimatisierte Luft verbunden ist. Der Elektromotor 12 dient in diesem Fall dem Antreiben eines nicht dar¬ gestellten Lüfterrades zum Transportieren der klimatisierten Luft. Der Elektromotor 12 weist einen rohrf rmigen Gehäuseabschnitt 18 auf, der mit Abstand von der Wand 20 der topfförmigen Aufnahme 10 in dem Aufnahmetopf 10 liegt. Der Elektromotor 12 stützt sich an der einen Stirnseite 22 an einer Schulter 24 des Aufnahmetopfes 10 in Achsrichtung ab. Damit der in dem Topf 10 sitzende Elektromotor 12 gekühlt wird, ist dieser innerhalb eines rohrformigen Gehäuseab¬ schnitts 18 belüftet. Die Luftzufuhr von außen erfolgt dabei in eine Kammer 26, die ringförmig ausgebildet ist und die sich aus dem zwi¬ schen dem rohrformigen Gehäuseabschnitt 18 des Elektromotors 12 und der inneren Topfwand 27 vorhandenen Abstand ergibt. Damit diese in die ring- oder rohrförmig ausgebildete, durch den Abstand 26 ge¬ bildete Kammer eingeführte Luft nicht in Achsrichtung des Motors am Topfrand 14 entweichen kann, ist im Bereich des Topfrandes 14 ein Bauelement 28 angeordnet. Das Bauelement 28 wird anhand der Figuren 3 bis 5 verdeutlicht. Es weist beim Ausführungsbeispiel drei aus einem elastischen Material bestehende, leistenför ige Abstützele¬ mente 30 auf, die einen im wesentlichen dreieckigen Querschnitt haben. Die drei Abstützelemente 30 sind durch bandartige, elastische Dichtelemente 32 miteinander verbunden. Es ergibt sich somit ein einstückiges, ringförmiges Bauelement 28 mit drei leistenförmigen Abstützelementen und drei elastischen Dichtelementen 32, die aus einem Elastomer gefertigt und einstückig ausgebildet sind. In diese Ringform sind die dreieckigen Abstützelemente 30 so integriert, daß jeweils eine Spitze 34 der im Durchschnitt dreieckigen Abstützele¬ mente 31 zur Kreismitte zeigt. Die Anordnung der Abstützelemente 30 ist so getroffen, daß sie sich parallel zur Achse des Kreises er¬ strecken. Wie insbesondere die Figuren 4 und 5 zeigen, ragen die Ab¬ stützelemente 30 mit ihrer der Spitze 34 gegenüberliegenden Drei¬ ecksbasis 36 über die Dichtelemente 32 hinaus, so daß sich Schwal¬ benschwanzförmige Ansätze ergeben. Weiter zeigt Figur 3, daß sich die leistenförmigen Abstützelemente 30 in Richtung der Kreisachse gesehen über die elastischen Dichtelemente 32 hinauserstrecken. Auch zeigen die Figuren 3 und 4, daß sich die Dreiecksform der Abstütz¬ elemente lediglich über einen ersten Teilbereich 38 erstreckt, der etwa der Breite der elastischen Dichtelemente 32 entspricht. Ein über diese elastischen Dichtelemente 32 hinausragender zweiter Teilabschnitt 40 der Abstützelemente 30 ist im Querschnitt kleiner als der erste Teilabschnitt 38. Es sind dort nämlich die basisnahen Ecken der Dreiecksform entfernt worden. Weiter zeigen die Figuren 3 bis 5, daß der Basisbereich 36 eines jeden Abstützelements 30 eine nach außen vorspringende Nase 42 aufweist, der eine Aus¬ sparung 44 in der Topfwand 20 zugeordnet ist. Schließlich zeigen noch die Figuren 3 bis 5, daß das Bauelement 28 eine in seine Kreis¬ form hineinragende Dichtlippe 46 hat, welche im Bereich der Abstütz¬ elemente 30 in diese übergeht. Die radiale Dicke 39 des bandartigen Dichtelements 32 ist kleiner als der Abstand 26 zwischen dem rohr¬ formigen Gehäuseabschnitt 18 des Elektromotors 12 und der inneren Topfwand 27 der Aufnahme 10.1 shows a pot-shaped receptacle 10 for an electric motor 12 shown in dash-dot lines. The pot-shaped receptacle 10 has a flange-like widening 16 near the pot rim 14, via which the pot-shaped receptacle 10 with wall parts, not shown, for example of guide shafts for the passenger compartment Air-conditioned air to be supplied to the motor vehicle is connected. In this case, the electric motor 12 serves to drive a fan wheel (not shown) for transporting the conditioned air. The electric motor 12 has a tubular housing section 18, which lies at a distance from the wall 20 of the pot-shaped receptacle 10 in the receptacle 10. The electric motor 12 is supported on one end face 22 on a shoulder 24 of the receptacle 10 in the axial direction. So that the electric motor 12 seated in the pot 10 is cooled, it is ventilated within a tubular housing section 18. The air supply from the outside takes place in a chamber 26, which is annular and which results from the distance between the tubular housing section 18 of the electric motor 12 and the inner pot wall 27. So that this air introduced into the annular or tubular chamber formed by the distance 26 cannot escape in the axial direction of the motor at the pot rim 14, a component 28 is arranged in the area of the pot rim 14. The component 28 is illustrated with reference to FIGS. 3 to 5. In the exemplary embodiment, it has three, strip-shaped support elements 30 made of an elastic material, which have an essentially triangular cross section. The three support elements 30 are connected to one another by band-like, elastic sealing elements 32. The result is a one-piece, ring-shaped component 28 with three strip-shaped support elements and three elastic sealing elements 32, which are made of an elastomer and are formed in one piece. The triangular support elements 30 are integrated into this ring shape in such a way that a tip 34 of the triangular support elements 31 points to the center of the circle. The arrangement of the support elements 30 is such that they extend parallel to the axis of the circle. As shown in FIGS. 4 and 5 in particular, the support elements 30 with their triangular base 36 opposite the tip 34 protrude beyond the sealing elements 32, so that dovetail-shaped approaches result. FIG. 3 further shows that the strip-shaped support elements 30, viewed in the direction of the circular axis, extend beyond the elastic sealing elements 32. FIGS. 3 and 4 also show that the triangular shape of the support elements only extends over a first partial area 38 which corresponds approximately to the width of the elastic sealing elements 32. A second section 40 of the support elements 30 projecting beyond these elastic sealing elements 32 is in cross section smaller than the first section 38. The corners of the triangular shape close to the base have been removed there. FIGS. 3 to 5 further show that the base region 36 of each support element 30 has an outwardly projecting nose 42, which is associated with a recess 44 in the pot wall 20. Finally, FIGS. 3 to 5 also show that the component 28 has a sealing lip 46 which projects into its circular shape and which merges into the support elements 30 in the region thereof. The radial thickness 39 of the band-like sealing element 32 is smaller than the distance 26 between the tubular housing section 18 of the electric motor 12 and the inner cup wall 27 of the receptacle 10.
Aus den Figuren 1 und 2 ist zu entnehmen, wie der elektrische Lüftermotor 12 in seiner topfförmigen Aufnahme 10 montiert ist. Figur 2 zeigt, daß die strichpunktiert dargestellten, leisten¬ förmigen Abstützelemente 30 um ein Maß in die Aufnahme 10 ragen, das größer ist als der Abstand 26 zwischen dem rohrf rmigen Gehäuseab¬ schnitt 10 des Elektromotors 12 und der inneren Topfwand 27 der Auf¬ nahme 10 (Fig. 1). Weiter sei noch erwähnt, daß der Durchmesser des Baulements 28 über die Innenkante der Dichtlippe 46 gemessen kleiner ist als der Außendurchmesser des rohrformigen Gehäuseabschnitts 18. Zur Montage des Elektromotors 12 wird zunächst in die topfformige Aufnahme 10 das Bauelement 28 eingebracht. Dazu weist die Aufnahme 10 an der Topfwand drei Haltenuten 50 auf, welche den überstehenden, schwalbenschwanzformigen Bereichen der Abstützelemente 30 zugeordnet sind. In diese schwalbenschwanzformigen Haltenuten 50 werden nun die Abstützelemente 30 eingebracht. Dabei ist die partielle Quer¬ schnittsverringerung der Abstützelemente 30 von Vorteil. In der in Fig. 1 dargestellten korrekten-Einbaulage des Bauelements 28 rasten die Nasen 42 der Abstützelemente 30 in ihre Aussparungen 42 in der Topfwand 20. Dadurch ist eine ordnungsgemäße Sicherung des Bau¬ elements 28 im Aufnahmetopf 10 sichergestellt. Danach wird der Elektromotor 12 in den so vorbereiteten Aufnahmetopf 10 in Richtung seiner Drehachse eingeschoben. Unter geringfügiger Verformung der dem rohrf rmigen Gehäuseabschnitt 18 zugewandten Spitze 34 der Ab¬ stützelemente 30 wird der Elektromotor 12 so in seine Aufnahme 10 hineingeschoben, bis er mit seiner Stirnseite 22 auf der Schulter 24 zur Anlage kommt. Die leistenförmigen Abstützelemente 30 sichern den Elektromotor 12 in seiner vorschriftsmäßigen, zentrischen Lage im Aufnahmetopf 10 und sorgen für die Dämpfung der auftretenden Schwin¬ gungen. Die bandartigen, elastischen Dichtelementabschnitte 32 zwi¬ schen den Abstützelementen 30 bewirken eine sichere Abdichtung der Beluftungskammer 26 zum Topfrand 14. Die in die ringförmige, durch den Abstand 26 gebildete Belüftungskammer eingeleitete Kühlluft wird nun durch die hier nicht dargestellten Belüftungsöffnungen im Motor¬ gehäuse gezwungen, so daß eine Motorüberhitzung nicht stattfinden kann. It can be seen from FIGS. 1 and 2 how the electric fan motor 12 is mounted in its cup-shaped receptacle 10. Figure 2 shows that the dash-dotted, strip-shaped support elements 30 protrude into the receptacle 10 by an amount that is greater than the distance 26 between the tubular housing section 10 of the electric motor 12 and the inner pot wall 27 of the receptacle 10 (Fig. 1). It should also be mentioned that the diameter of the structural element 28 measured over the inner edge of the sealing lip 46 is smaller than the outer diameter of the tubular housing section 18. To assemble the electric motor 12, the structural element 28 is first introduced into the pot-shaped receptacle 10. For this purpose, the receptacle 10 has three holding grooves 50 on the pot wall, which are assigned to the protruding, dovetail-shaped regions of the support elements 30. The support elements 30 are now introduced into these dovetail-shaped holding grooves 50. The partial reduction in cross section of the support elements 30 is advantageous here. In the correct installation position of the component 28 shown in FIG. 1, the lugs 42 of the support elements 30 snap into their recesses 42 in the pot wall 20. This ensures proper securing of the component 28 in the receptacle 10. Then the electric motor 12 in the so prepared pot 10 in the direction inserted its axis of rotation. With slight deformation of the tip 34 of the support elements 30 facing the tubular housing section 18, the electric motor 12 is pushed into its receptacle 10 until its end face 22 comes to rest on the shoulder 24. The strip-shaped support elements 30 secure the electric motor 12 in its correct, central position in the receptacle 10 and ensure the damping of the vibrations that occur. The band-like, elastic sealing element sections 32 between the support elements 30 bring about a secure sealing of the ventilation chamber 26 to the pot rim 14. The cooling air introduced into the annular ventilation chamber formed by the distance 26 is now forced through the ventilation openings (not shown here) in the motor housing. so that engine overheating cannot take place.
