Description
Die Erfindung betrifft eine Bürstenplatte, insbesondere für einen Kühlerlüftermotor, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a brush plate, in particular for a radiator fan motor, according to the preamble of the claim 1.
In der DE 199 34 558 A1 wird eine Bürstenplatte für einen Kollektormotor mit einem Bürstenschacht beschrieben, in dem eine Kohlebürste mit einer Doppelrollbandfeder belastet gegen den Kollektor gedrückt wird. Zur Kontaktierung der Kohlebürste mit einer Drosselspule wird ein Kohlebürstenseil durch eine Durchstecköffnung radial aus dem Bürstenschacht herausgeführt. Die Drosselspulen sind im Wesentlichen senkrecht zur Bürstenplatte angeordnet.In DE 199 34 558 A1, a brush plate for a Collector motor described with a brush shaft, in the a carbon brush loaded with a Doppelrollbandfeder against the collector is pressed. For contacting the carbon brush with a choke coil is a carbon brush rope through a Through opening radially led out of the brush shaft. The choke coils are substantially perpendicular to Brush plate arranged.
In der DE 100 64 501 A1 wird eine Bürstenplatte für einen Elektromotor mit einem Bürstenschacht beschrieben, in dem eine Kohlebürste mit einer Schraubenfeder belastet gegen einen Schleifpartner gedrückt wird. Zur Kontaktierung der Kohlebürste mit einer Drosselspule wird ein Kohlebürstenseil durch eine Aussparung axial aus dem Bürstenschacht herausgeführt. Die Drosselspule ist im Wesentlichen senkrecht zur Bürstenplatte angeordnet.In DE 100 64 501 A1, a brush plate for a Electric motor described with a brush shaft in which a carbon brush loaded with a coil spring against a Abrasive partner is pressed. For contacting the carbon brush with a choke coil becomes a carbon brush rope axially led out of the brush shaft through a recess. The choke coil is substantially perpendicular to Brush plate arranged.
Aufgabe der Erfindung ist es, eine Bürstenplatte, insbesondere für einen Kühlerlüftermotor anzugeben, die eine kompakte axiale Bauweise für einen Motor unterstützt.The object of the invention is a brush plate, in particular for a radiator fan motor to provide a compact Axial construction supported for a motor.
Die Erfindung löst diese Aufgabe durch Bereitstellung einer Bürstenplatte, insbesondere für einen Kühlerlüftermotor mit den Merkmalen des Patentanspruchs 1.The invention solves this problem by providing a Brush plate, in particular for a radiator fan motor with the features of claim 1.
Vorteilhafte Ausführungsformen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben. Advantageous embodiments and developments of the invention are indicated in the dependent claims.
Der Hauptgedanke der Erfindung besteht darin, bei einem Bürstenschacht im vorderen Bereich eine Öffnung zum axialen Einführen eines Kohlebürstenseils und eine seitliche Aussparung zum radialen Verschieben des Kohlebürstenseils vorzusehen. Dadurch ist es in vorteilhafter Weise möglich, ein zur Kontaktierung einer Kohlebürste erforderliches Kohlebürstenseil Platz sparend in der Art eines Bajonettprinzips zu verlegen. D. h. das Kohlebürstenseil wird axial in den Bürstenschacht eingeführt und anschließend mit der Kohlebürste radial nach außen verschoben. Dadurch wird ein axiales oder radiales Herausführen des Kohleseils aus dem Bürstenschacht vermieden. Eine Verschlusskappe am hinteren Ende des Bürstenschachts wird überflüssig, wodurch die Kohlebürste zur Verlängerung der Lebensdauer effektiv verlängert werden kann. Durch die beschriebene Verlegung des Kohlebürstenseils kann in vorteilhafter Weise der Bauraum in axialer Richtung verkleinert werden, ohne dass die Gefahr eines Kurzschlusses aufgrund einer Beschädigung des Kohlebürstenseils durch einen rotierenden Läufer besteht.The main idea of the invention is, in a brush shaft in the front area an opening for axial insertion a carbon brush cable and a side recess to provide for radial displacement of the carbon brush cable. This makes it possible in an advantageous manner, one for contacting a carbon brush required carbon brush cable To save space in the manner of a bayonet principle. Ie. the carbon brush rope becomes axially in the brush shaft introduced and then radially with the carbon brush moved outside. This will cause an axial or radial lead out avoided the coal rope from the brush shaft. A cap at the back of the brush shaft becomes redundant, causing the carbon brush to lengthen the life can be extended effectively. By the described laying the carbon brush cable can in an advantageous Way the space to be reduced in the axial direction, without the risk of a short circuit due to a Damage to the carbon brush cable caused by a rotating Runner exists.
In Ausgestaltung der Bürstenplatte ist im hinteren Bereich des Bürstenschachtes eine Druckfeder angeordnet, welche sich auf einem Bürstenschachtverschluss abstützt und die Kohlebürste zur elektrischen Kontaktierung mit einer Federkraft in Richtung eines Schleifrings oder eines Kollektors belastet.In embodiment of the brush plate is in the rear area arranged a compression spring of the brush shaft, which is supported on a brush shaft closure and the carbon brush for electrical contact with a spring force in Direction of a slip ring or a collector charged.
In weiterer vorteilhafter Ausgestaltung ist eine Drosselspule so auf der Bürstenplatte angeordnet, dass ihre Längsausdehnung parallel zur Bürstenplatte verläuft. Dadurch wird die Verkleinerung des axialen Bauraums weiter unterstützt.In a further advantageous embodiment is a choke coil so arranged on the brush plate that its longitudinal extent runs parallel to the brush plate. This will be the Reduction of the axial space further supported.
Das Kohlebürstenseil zur Kontaktierung der Drosselspule mit der Kohlebürste kann außerhalb des Bürstenschachtes beispielsweise im Wesentlichen parallel zur Bürstenplatte und/oder radial zur Mittelachse der Bürstenplatte verlegt sein. The carbon brush cable for contacting the choke coil with The carbon brush can outside the brush shaft, for example substantially parallel to the brush plate and / or be moved radially to the central axis of the brush plate.

2 mindestens zwei Bürstenschächte 4 zur Aufnahme einer
Kohlebürste 6. Es können auch mehr oder weniger Bürstenschächte
vorgesehen sein. Im hinteren Teil des Bürstenschachts
4 ist eine Druckfeder 8, beispielsweise eine Schraubendruckfeder,
angeordnet, welche die Kohlebürste 6 in Richtung
des Bürstenplattenmittelpunktes und damit in Richtung
eines nicht dargestellten Schleifpartners, beispielsweise eines
Schleifrings oder eines Kollektors, mit einer Federkraft
beaufschlagt.As can be seen from FIG. 1, the brush plate comprises
2 at least two brush shafts 4 for receiving a

aus dem Bürstenschacht 4 herausgeführt, so dass auf eine
Durchführung für das Kohlebürstenseil 14 am hinteren Ende des
Bürstenschachtes 4 und damit auch auf eine Verschlusskappe
verzichtet werden kann.The brush shaft 4 has an axial in the front area
Direction extending opening 10 and two
Wie aus der Figur 1 weiter ersichtlich ist, stützt sich die
Druckfeder 8 auf einem Bürstenschachtverschluss 16 ab. Der
Bürstenschachtverschluss 16 umfasst keine Verschlusskappe, so

14 zur Kontaktierung der Drosselspule 18 mit
der Kohlebürste 6 außerhalb des Bürstenschachtes 4 im Wesentlichen
parallel zur Bürstenplatte 2 verlegt, um eine möglichst
geringe axiale Ausdehnung zu erzielen. Zudem ist das
Kohlebürstenseil 14 im Wesentlichen radial zur Mittelachse
der Bürstenplatte 2 verlegt.As can also be seen from FIG. 1, the carbon brush cable is also used
14 for contacting the

als Bürstenplatte für einen 4poligen Motor mit 2 Kohlen
ausgeführt und umfasst daher zwei Bürstenschächte 4 mit
zugehörigen Kohlebürsten 6, Kohlebürstenseilen 14 und
Drosselspulen 18.The brush plate 2 shown in FIG. 1 is exemplary
as a brush plate for a 4-pole engine with 2 coals
executed and therefore includes two brush shafts 4 with
associated carbon brushes 6,

Bürstenschachtes 4 dargestellt ist. Die zweite seitliche Aussparung
12 ist durch eine in der Seitenwand des Bürstenschachts
4 verlaufende Nut gebildet, die der Belüftung des
Bürstenschachts 4 dient. Die gegenüberliegende seitliche Aussparung
12, die in Figur 1 dargestellt ist, dient der radialen
Verschiebung des Kohlebürstenseils 14 nach außen.FIG. 2 shows the brush plate 2 according to FIG. 1 in side view,
