Abstract
Description
Die Erfindung betrifft eine Förderpumpe für eine Scheibenreinigungsanlage eines Kraftfahrzeuges, die innerhalb eines Gehäuses einen Elektromotor und ein von dem Elektromotor antreibbares Pumpenlaufrad aufweist.The invention relates to a feed pump for a windshield cleaning system of a motor vehicle having an electric motor and a pump impeller driven by the electric motor within a housing.
Aus der
Es ist Aufgabe der vorliegenden Erfindung, eine Förderpumpe der eingangs genannten Gattung dahingehend zu verbessern, dass deren Herstellung vereinfacht und kostengünstiger wird.It is an object of the present invention to improve a feed pump of the type mentioned in such a way that their production is simplified and less expensive.
Diese Aufgabe wird durch eine Förderpumpe mit den kennzeichnenden Merkmalen des unabhängigen Patentanspruchs 1 gelöst. Dabei ist vorgesehen, dass das Gehäuse teilbar ausgebildet ist und entlang der Längsachse axial in zwei Gehäusehälften geteilt ist. Die beiden Gehäusehälften sind im Wesentlichen symmetrisch entlang einer Spiegelebene, die durch die Längsachse der Förderpumpe verläuft, ausgebildet. Durch diese Maßnahme wird eine Minimierung der Anzahl von Bauteilen erreicht. Es sind kostengünstigere Werkstoffe einsetzbar und die einfache Montage führt zu einer Kostenreduzierung.This object is achieved by a feed pump with the characterizing features of
Eine vorteilhafte Weiterbildung des Erfindungsgegenstandes sieht vor, dass die beiden Gehäusehälften Rastverbindungselemente aufweisen, mit denen die Gehäusehälften fest miteinander verbunden werden. Dabei ist eine Dichtung vorgesehen ist, die einerseits die Pumpenkammer gegenüber dem Elektromotor abdichtet und andererseits die beiden Gehäusehälften gegeneinander abdichtet und die Pumpenkammer bilden.An advantageous development of the subject invention provides that the two housing halves have latching connection elements with which the housing halves are firmly connected to each other. In this case, a seal is provided which on the one hand seals the pump chamber relative to the electric motor and on the other hand, the two housing halves seals against each other and form the pump chamber.
In einer alternativen Ausführungsform sind die beiden Gehäusehälften mittels einer stoffschlüssigen Verbindung, die als Schweißverbindung oder als Klebverbindung ausgebildet ist, miteinander verbunden. In dieser Alternativausführung ist eine Dichtung vorgesehen, die lediglich die Pumpenkammer gegenüber dem Elektromotor abdichtet. Eine Abdichtung der Gehäusehälften gegeneinander ist bereits durch die Schweißverbindung realisiert. Dieses Konzept begünstigt den Einsatz von günstigen Massenkunststoffen, wie Polypropylen oder Polyethylen, da das Gehäuse keine Schnapp- oder Rastverschlüsse enthält.In an alternative embodiment, the two housing halves are connected to each other by means of a material connection, which is designed as a welded connection or as an adhesive bond. In this alternative embodiment, a seal is provided which seals only the pump chamber with respect to the electric motor. A sealing of the housing halves against each other is already realized by the weld. This concept favors the use of cheap bulk plastics, such as polypropylene or polyethylene, since the housing contains no snap or snap closures.
Eine weitere vorteilhafte Weiterbildung sieht vor, dass eine Gehäusehälfte eine Ausnehmung aufweist, durch die die elektrischen Kontakte des Elektromotors geführt werden.A further advantageous embodiment provides that a housing half has a recess through which the electrical contacts of the electric motor are guided.
Der Vorteil der vorliegenden Erfindung liegt in der Minimierung der Anzahl von Bauteilen und von Montageprozessen. Ebenso können die Werkzeuge für die Herstellung der Gehäusehälften deutlich einfacher und damit kostengünstiger gestaltet werden.The advantage of the present invention is the minimization of the number of components and assembly processes. Likewise, the tools for the production of the housing halves can be made significantly simpler and thus cheaper.
Die Erfindung wird nachfolgend anhand zweier Ausführungsbeispiele im Zusammenhang mit der beiliegenden Zeichnung näher erläutert. In der Zeichnung zeigen:The invention will be explained in more detail with reference to two embodiments in conjunction with the accompanying drawings. In the drawing show:
