Description

Die Erfindung betrifft ein Gebläse in Radialbauweise einer Heizungs- und/oder Klimaanlage, insbesondere eines Kraftfahrzeugs mit einem den Elektromotor haltenden Motorhalter, an dem außen Arme vorstehen, die über Dämpfungselemente am Gebläseeinlaufring und ferner am Gebläsegehäuse befestigt sind.The invention relates to a blower in the radial design of a heating and / or air conditioning system, in particular a motor vehicle with a motor holder holding the electric motor, on the outside of which project arms which are fastened to the blower inlet ring and also to the blower housing via damping elements.

Es ist bekannt, einen Motorhalter eines Radialgebläses zusammen mit dem Einlaufring am Gebläsegehäuse zu befestigen. Hierbei sind Dämpfungselemente an den Befestigungsstellen zwischen Motorhalter und Einlaufring angeordnet. Es hat sich gezeigt, daß diese Konstruktion nicht ausreicht, um vom Elektromotor und Lüfterrad erzeugte Schwingungen zu eliminieren, so daß die Schwingungen im Kraftfahrzeuginneren zu stark hörbar sind.It is known to fasten a motor holder of a radial blower together with the inlet ring on the blower housing. Damping elements are arranged at the fastening points between the motor bracket and the inlet ring. It has been shown that this construction is not sufficient to eliminate vibrations generated by the electric motor and fan wheel, so that the vibrations inside the motor vehicle are too audible.

Aufgabe der Erfindung ist es, ein Gebläse der eingangs genannten Art so zu verbessern, daß Schwingungen des Motors und Lüfterrades nicht auf außen angeschlossene Teile übertragen werden.The object of the invention is to improve a fan of the type mentioned in such a way that vibrations of the motor and fan wheel are not transmitted to externally connected parts.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Befestigungsstellen zwischen Einlaufring und Gebläsegehäuse und/oder Anlagengehäuse getrennt von den Befestigungen zwischen dem Motorhalter und dem Einlaufring angeordnet sind, und daß die Befestigung zwischen dem Motorhalter und dem Einlaufring die Dämpfungselemente aufweisen.This object is achieved in that the fastening points between the inlet ring and blower housing and / or system housing are arranged separately from the fastenings between the motor holder and the inlet ring, and that the fastening between the motor holder and the inlet ring have the damping elements.

Bei einer solchen Konstruktion werden Schwingungen des Motors und Lüfterrades nicht auf das Gebläsegehäuse und damit auch nicht auf das Gehäuse der Heizungs-/Klimaanlage und die Karosserie übertragen. Die von dem Gebläse erzeugten Schwingungen sind damit im Kraftfahrzeuginneren kaum wahrnehmbar. Hierbei ist die Konstruktion einfach und von kleinen Außenabmessungen.With such a construction, vibrations of the motor and fan wheel are not transmitted to the blower housing and thus not to the housing of the heating / air conditioning system and the body. The vibrations generated by the blower are therefore hardly perceptible in the interior of the motor vehicle. The construction is simple and of small external dimensions.

Vorzugsweise wird hierzu vorgeschlagen, daß die Befestigungen zwischen Einlaufring und Gebläse bzw. Anlagengehäuse an der Außenseite des Einlaufrings und die Befestigung zwischen Motorhalter und Einlaufring an der Innenseite des Einlaufrings angeordnet sind. Hierdurch sind die Dämpfungselemente weit nach innen gerückt und dann nahe der Entstehung der Schwingungen, so daß sie optimal aufgefangen werden.For this purpose, it is preferably proposed that the fastenings between the inlet ring and the blower or system housing be arranged on the outside of the inlet ring and the fastening between the motor holder and the inlet ring on the inside of the inlet ring. As a result, the damping elements are moved far inward and then close to the origin of the vibrations, so that they are optimally absorbed.

Besonders vorteilhaft ist es, wenn die Dämpfungselemente der Befestigung zwischen dem Motorhalter und dem Einlaufring zapfen- oder stiftförmig sind und mit einer Seite formschlüssig in Öffnungen der Arme des Motorhalters und mit der anderen Seite in Öffnungen des Einlaufrings gehalten sind. Damit wird die Befestigung zwischen Motorhalter und Einlaufring allein durch die Dämpfungselemente vorgenommen, ohne zusätzliche Befestigungsmittel wie z.B. Schrauben zu erfordern. Hierbei ist von Vorteil, wenn das zylindrische Dämpfungselement an beiden Enden koaxiale Ringnuten aufweist, mit denen es in Bohrungen/Öffnungen des Motorhalters und des Einlaufrings einliegt.It is particularly advantageous if the damping elements of the fastening between the motor holder and the inlet ring are peg-shaped or pin-shaped and are held with one side in a form-fitting manner in openings in the arms of the motor holder and with the other side in openings of the inlet ring. This means that the fastening between the motor bracket and the inlet ring is carried out solely by the damping elements, without requiring additional fastening means such as screws. It is advantageous if the cylindrical Damping element has coaxial ring grooves at both ends, with which it lies in bores / openings of the motor holder and the inlet ring.

Vorzugsweise wird vorgeschlagen, daß die Achse des zylindrischen Dämpfungselements parallel zur Motorachse ist. Eine zusätzliche Sicherung der Befestigung der Dämpfungselemente wird dann erreicht, wenn das Dämpfungselement zumindest an einem seiner Enden von einer Rastkappe umgeben ist, die den Halt des Dämpfungselements in der Bohrung/Öffnung sichert.It is preferably proposed that the axis of the cylindrical damping element is parallel to the motor axis. An additional securing of the fastening of the damping elements is achieved if the damping element is surrounded at least at one of its ends by a locking cap which ensures that the damping element is held in the bore / opening.

Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden im folgenden näher beschrieben. Es zeigen:

Figur 2

Figur 3
einen axialen Schnitt durch eine Rastkappe.
Embodiments of the invention are shown in the drawing and are described in more detail below. Show it:
Figure 1
a side view of the blower with motor bracket and inlet ring,
Figure 2
an axial section in the region of a damping element and
Figure 3
an axial section through a locking cap.

Ein nicht dargestellter Elektromotor mit der Achse 1 treibt ein nicht dargestelltes Laufrad eines Gebläses 2 an, das die Luft axial ansaugt und radial abgibt. Das Laufrad umgibt hierbei den Elektromotor koaxial.An electric motor (not shown) with the axis 1 drives an impeller (not shown) of a blower 2, which sucks in the air axially and releases it radially. The impeller coaxially surrounds the electric motor.

Der Elektromotor ist von einem zylindrischen, insbesondere topfförmigen Motorhalter 3 koaxial umgehen, der auf der Seite, mit der das Gebläse an einer Heizungs- und/oder Klimaanlage eines Kraftfahrzeugs befestigt wird, drei radiale Arme 4 aufweist, die am Motorhalter 3 angeformt sind. In jedem Arm 4 ist eine kreisrunde Öffnung 5 eingebracht, deren Rand in einer Ringnut 6 eines elastischen Dämpfungselementes 7, insbesondere aus Gummi oder Weichkunststoff liegt.The electric motor is coaxially bypassed by a cylindrical, in particular pot-shaped, motor holder 3, which has three radial arms 4 on the side with which the blower is attached to a heating and / or air conditioning system of a motor vehicle, which arms are formed on the motor holder 3. A circular opening 5 is made in each arm 4, the edge of which is in an annular groove 6 an elastic damping element 7, in particular made of rubber or soft plastic.

Das zapfen- oder stiftförmige Dämpfungselement 7 weist eine größere axiale Länge L als Breite bzw. Durchmesser D auf. Es besitzt an beiden Enden jeweils eine Ringnut 6, wobei in der zweiten Ringnut der Rand einer Öffnung 8 einliegt, die in einem Vorsprung 9 eines Einlaufringes 10 angeordnet ist. Das Dämpfungselement 7 bildet somit eine Verbindung zwischen dem Arm 4 des Motorhalters 3 und dem Vorsprung 9 des Einlaufringes 10, ohne daß an dieser Verbindungsstelle weitere Befestigungsmittel wie Schrauben erforderlich sind. Allein durch die formschlüssigen Verbindungen der zwei Teile 4 und 9 über die zwei Ringnuten 6 an beiden Enden des Dämpfungselementes 7 wird ein sicherer und schwingungsmindernder Halt erreicht.The pin-shaped or pin-shaped damping element 7 has a greater axial length L than the width or diameter D. It has an annular groove 6 at both ends, the edge of an opening 8 lying in the second annular groove, which is arranged in a projection 9 of an inlet ring 10. The damping element 7 thus forms a connection between the arm 4 of the motor holder 3 and the projection 9 of the inlet ring 10, without further fastening means such as screws being required at this connection point. A secure and vibration-reducing hold is achieved solely by the positive connections of the two parts 4 and 9 via the two ring grooves 6 at both ends of the damping element 7.

Hierbei liegen die Dämpfungselemente 7 im inneren Bereich des metallenen Einlaufringes 10, während die Befestigungsstellen des Einlaufringes 10 an der Heizungs- und/oder Klimaanlage, insbesondere an dessen Gehäuse außen liegen. Diese äußeren Befestigungsstellen werden durch vier Arme 11 geschaffen, die an der Außenseite des Einlaufringes 10 radial angeformt sind. Die drei Arme 4 des Motorhalters 3 liegen in Winkelstellungen, die nicht mit den vier Armen 11 übereinstimmen. Dies führt zu einer weiteren Verminderung einer Übertragung von Schwingungen.The damping elements 7 are located in the inner region of the metal inlet ring 10, while the fastening points of the inlet ring 10 are on the outside of the heating and / or air conditioning system, in particular on its housing. These outer fastening points are created by four arms 11, which are formed radially on the outside of the inlet ring 10. The three arms 4 of the motor holder 3 are in angular positions that do not match the four arms 11. This leads to a further reduction in the transmission of vibrations.

Um den Halt des Dämpfungselementes 7 in der Öffnung 5 des Armes 4 zu verbessern, können an dieser Stelle Rastkappen 12 befestigt sein, die als zusätzliche Sicherung dienen. Diese Rastkappen übergreifen ein Ende des Dämpfungselementes 4 und durchgreifen die Öffnung 5.In order to improve the hold of the damping element 7 in the opening 5 of the arm 4, locking caps 12 can be attached at this point, which serve as additional security. These locking caps overlap one end of the damping element 4 and pass through the opening 5.
