Abstract
Description
Die Erfindung bezieht sich auf einen Antrieb für ein Flurförderzeug nach der im Oberbegriff von Anspruch 1 näher definierten Art.The The invention relates to a drive for an industrial truck after further defined in the preamble of claim 1 Art.
Gattungsgemäße Antriebe für Flurförderzeuge beinhalten einen Lenkmotor und einen Fahrmotor, welche koaxial zueinander angeordnet sind. Der Fahrmotor treibt über ein Stirnradgetriebe und ein Kegelradgetriebe ein Fahrzeugrad an.generic Drives for industrial trucks include one Steering motor and a traction motor, which are arranged coaxially to each other are. The drive motor drives via a spur gear and a bevel gear on a vehicle.
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Antrieb für ein Flurförderzeug zu schaffen, bei welchem der Lenkmotor und der Fahrmotor auf einfache Weise miteinander verbindbar sind, und die Drehzahlen des Lenkmotors und des Fahrmotors auf einfache Weise detektierbar sind.Of the present invention is based on the object, a drive to create an industrial truck in which the steering motor and the traction motor are easily connectable to each other, and the speeds of the steering motor and the drive motor to simple Way are detectable.
Die Aufgabe wird mit einem, auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden, gattungsgemäßen Antrieb für ein Flurförderzeug gelöst.The The object is with a, even the characterizing features of the main claim having, generic drive for an industrial truck solved.
Erfindungsgemäß weist der Antrieb für ein Flurförderzeug einen Lenkmotor und einen Fahrmotor auf, welche koaxial zueinander angeordnet sind. Der Stator des Lenkmotors und der Stator des Fahrmotors sind über ein ringförmiges Verbindungselement miteinander verbunden, welches aus einem elektrisch nichtleitenden Material besteht. Vorzugsweise ist dieses elektrisch isolierende Material ein temperaturstabiler Kunststoff, wie beispielsweise der Kunststoff PA 66 GFXL.According to the invention the drive for a truck a steering motor and a traction motor, which are arranged coaxially with each other. Of the Stator of the steering motor and the stator of the traction motor are over an annular connecting element connected to each other, which consists of an electrically non-conductive material. Preferably This electrically insulating material is a temperature-stable Plastic, such as the plastic PA 66 GFXL.
In einer weiteren Ausgestaltungsform der Erfindung sind in diesem aus isolierendem Material bestehenden ringförmigen Verbindungsteil Drehzahlsensoren angeordnet. Diese sind vorzugsweise eingegossen, um eine exakte Positionierung der Drehzahlsensoren zu gewährleisten.In Another embodiment of the invention are in this insulating material existing annular connecting part Speed sensors arranged. These are preferably cast in, to ensure an exact positioning of the speed sensors.
Es besteht jedoch auch die Möglichkeit, im ringförmigen Element Aufnahmen für die Drehzahlsensoren anzuordnen.It However, there is also the possibility in the annular To arrange element recordings for the speed sensors.
In einer weiteren Ausgestaltungsform sind im ringförmigen Element druckfeste Bauteile integriert, wie beispielsweise Metallstifte, welche zur Abstützung der Axialkräfte, welche von den beiden Motoren auf das ringförmige Verbindungsteil wirken, geeignet sind. Das ringförmige Element kann Zentrierungen aufweisen, in welche der Stator der Motoren eingreift.In a further embodiment are in the annular Integrated element pressure resistant components, such as metal pins, which for supporting the axial forces, which from the two motors on the annular connecting part act, are suitable. The annular element may have centerings, in which engages the stator of the motors.
In einer weiteren Ausgestaltungsform der Erfindung weist das ringförmige Element mindestens einen Steg auf, welcher sich entlang eines Motors erstreckt und innerhalb welchem elektrisch leitende Verbindungen angeodnet sind. Dadurch ist gewährleistet, dass die elektrischen Verbindungen des Antriebs betriebssicher verlegt werden können.In a further embodiment of the invention, the annular Element at least one bridge, which extends along an engine extends and within which electrically conductive connections are angeodnet. This ensures that the electrical Connections of the drive can be laid reliably.
In einer Ausgestaltungsform der Erfindung weist das ringförmige Verbindungsteil zwei Stege auf, wobei ein Steg entlang des Fahrmotors bis zu einer Bremse und ein Steg entlang des Lenkmotors bis zum Getriebegehäuse reicht. In den Stegen verlaufen elektrisch leitende Leitungen, wie beispielsweise gestanzte Kupfergitter, wobei die Kupfergitter vom Kunststofff umspritzt sind. Am Ende des Lenkmotors kann der Steg mit einem Schalter für eine Kalibrierung, beispielsweise einem Null-Schalter für eine Referenzfahrt, verbunden sein.In an embodiment of the invention, the annular Connecting part two webs, with a web along the drive motor up to a brake and a bridge along the steering motor to the Transmission housing is sufficient. In the webs run electrically conductive lines, such as stamped copper mesh, wherein the copper grids are encapsulated by Kunststofff. At the end of the steering motor can the bridge with a switch for a calibration, for example a zero switch for a homing, be connected.
Es
besteht auch die Möglichkeit, die Leitungen von den Drehzahlsensoren über
die Stege bis zu einer elektronischen Steuereinheit zu führen.
Dadurch werden alle Leitungen gegen mögliche Beschädigung
während der Montage und im Betrieb des Antriebs geschützt.
Die anderen Bauteile des Antriebs sind wie in der
