Description

Die Erfindung bezieht sich auf eine Stromversorgung für ein Flurförderzeug nach Patentanspruch 1.The invention relates to a power supply for an industrial truck according to claim 1.

Deichselgeführte Flurförderzeuge sind häufig mit einem elektrischen Antrieb zur Unterstützung der Hubfunktion und für den Fahrbetrieb ausgestattet. Dazu wird eine Vielzahl elektrischer und elektromechanischer Komponenten in das Flurförderzeug eingebaut, beispielsweise ein Motor für den Fahrantrieb, ein weiterer Motor für eine Hydraulikpumpe, eine Batterie, Bedienelemente und elektronische Steuerungen für die Motoren. Für die Stromversorgung der einzelnen Komponenten sind geeignete Verbindungen zur Stromquelle zu schaffen, die einer Reihe von Anforderungen unterliegen, insbesondere hinsichtlich der Zuverlässigkeit und der Sicherheit des Betriebs.Tiller-guided industrial trucks are often equipped with an electric drive to support the lifting function and for driving. For this purpose, a variety of electrical and electromechanical components is installed in the truck, such as a motor for the drive, another motor for a hydraulic pump, a battery, controls and electronic controls for the engines. For the power supply of the individual components are appropriate connections to the power source to create, which are subject to a number of requirements, especially in terms of reliability and safety of operation.

In der Regel werden die Hauptverbraucher des Flurförderzeugs über ein Schütz mit Strom versorgt, das in der Nähe des Verbrauchers bzw. von dessen Steuerung angeordnet ist. Zur Ansteuerung der Schütze besteht eine Verbindung zu den Bedienelementen bzw. zu einer zugeordneten Steuerung, über die die Kontakte der Schütze im Falle eines entsprechende Steuerbefehls geschlossen werden, um die Verbraucher mit Strom zu versorgen. Die Bedienelemente sind häufig am Deichselkopf angeordnet.In general, the main consumers of the truck are powered by a contactor, which is located in the vicinity of the consumer or by its control. To control the contactors there is a connection to the controls or to an associated control, via which the contacts of the contactors are closed in the case of a corresponding command to supply the consumers with power. The controls are often located on the tiller head.

Weiterhin gibt es eine Notabschaltung, mit der in einer Gefahrensituation die Stromversorgung schnell unterbrochen werden kann. Diese kann aus Sicherheitsgründen vorteilhaft in Form einer mechanisch betätigbaren Trennung der Kontakte der Schütze ausgeführt sein. Um die Notabschaltung zu betätigen, wird an leicht erreichbarer Stelle, z.B. auf der Oberseite des Gehäuses des Antriebsteils des Flurförderzeugs, ein Betätigungselement wie z.B. ein Schlagkopf angeordnet. Drücken bzw. Schlagen auf dieses Betätigungselement bewirkt über eine mechanische Verbindung ein Trennen der Kontakte der Schütze.Furthermore, there is an emergency shutdown with which the power supply can be quickly interrupted in a dangerous situation. For safety reasons, this can advantageously be designed in the form of a mechanically operable separation of the contacts of the contactors. In order to operate the emergency shutdown, it is located in an easily accessible place, e.g. on the upper side of the housing of the drive part of the truck, an actuating element such as e.g. arranged a percussion head. Pressing or hitting on this actuating element causes a separation of the contacts of the contactors via a mechanical connection.

In Flurförderzeugen der genannten Art ist meist auch eine Hupe vorgesehen, die von einem am Deichselkopf angeordneten Bedienelement betätigt wird. Mit der Hupe kann ein akustisches Warnsignal abgegeben werden.In industrial trucks of the type mentioned a horn is usually provided, which is operated by a arranged on the tiller head control. The horn can sound an audible warning.

Bei herkömmlichen Flurförderzeugen sind die genannten Komponenten über das Fahrzeug verteilt angeordnet. Die Schütze sind z.B. häufig mit einer Steuerung für den jeweiligen Motor kombiniert bzw. in dessen Nähe angeordnet. Die einzelnen Komponenten müssen bei der Entwicklung des Fahrzeugs individuell untergebracht werden.In conventional industrial trucks, said components are distributed over the vehicle. The contactors are e.g. often combined with a control for the respective engine or arranged in the vicinity thereof. The individual components must be individually housed in the development of the vehicle.

Aus der Druckschrift DE 102 24 168 A1 ist eine Schaltungsanordnung zur Steuerung elektromotorischer Antriebsmittel eines fahrbaren Arbeitsgerätes, insbesondere eines Flurförderzeuges, bekannt. Die Schaltungsanordnung weist Anschlüsse für die Verbindung mit einer Bordbatterie, eine elektronische Leistungsendstufe und eine elektronische Steuerstufe zur Steuerung der Leistungsendstufe auf. Außerdem hat die bekannte Schaltungsanordnung Hochstromanschlüsse zum Anschluss eines Fahr-, Pumpen- und Lenkmotors. Die genannten Elemente der Schaltungsanordnung sind in einem gemeinsamen Gehäuse angeordnet. Davon ausgehend ist die Aufgabe der Erfindung, eine Stromversorgung für ein Flurörderzeug zur Verfügung zu stellen, die unabhängig von den jeweiligen Gegebenheiten des Flurförderzeugs einfach und kostengünstig hergestellt und eingebaut werden kann.From the publication DE 102 24 168 A1 is a circuit arrangement for controlling the electromotive drive means of a mobile working device, in particular an industrial truck, known. The circuit arrangement has connections for connection to an on-board battery, an electronic power output stage and an electronic control stage for controlling the power output stage. In addition, the known circuit arrangement high current connections for connection of a driving, pumping and steering motor. The said elements of the circuit arrangement are arranged in a common housing. On this basis, the object of the invention to provide a power supply for a forklift available that can be easily and inexpensively manufactured and installed regardless of the particular circumstances of the truck.

Diese Aufgabe wird gelöst durch eine Stromversorgung für ein Flurförderzeug, insbesondere für ein deichselgeführtes Flurförderzeug, mit den Merkmalen des Patentanspruchs 1.This object is achieved by a power supply for an industrial truck, in particular for a tiller-guided industrial truck, with the features of patent claim 1.

Die erfindungsgemäße Stromversorgung hat

  • einen Hochstromanschluß für den Anschluß an eine Batterie,
  • mindestens eine steckbare Sicherung,
  • ein Hauptschütz zur Bestromung eines Antriebsmotors bzw. seiner Steuerung und wahlweise eines Hydraulikpumpenmotors bzw. seiner Steuerung,
  • einen mehrpoligen Steckverbinder zum Anschluß einer Steuerung für die Stromversorgung, und
  • Hochstromanschlüsse zum Anschluß der Steuerung des Antriebsmotors und gegebenenfalls weiterer Verbraucher,
wobei im Gehäuse des Antriebsteils des Flurförderzeugs ein einziger Träger vorgesehen ist, in oder an dem die vorstehend genannten Komponenten vormontiert angebracht sind.The power supply according to the invention has
  • a high current connection for connection to a battery,
  • at least one pluggable fuse,
  • a main contactor for energizing a drive motor or its control and optionally a hydraulic pump motor or its control,
  • a multi-pin connector for connecting a controller for the power supply, and
  • High current connections for connection of the control of the drive motor and optionally further consumers,
wherein in the housing of the drive part of the truck, a single carrier is provided, in or on which the aforementioned components are mounted pre-assembled.

Die wesentlichen elektromechanischen Komponenten der Stromversorgung werden also als kompaktes Modul mit einem einzigen Träger gefertigt. Der Träger faßt die Komponenten zu einer stabilen Einheit zusammen und kann vorteilhaft als Montageblech, an dem die Komponenten verschraubt werden, ausgeführt sein. Das Stromversorgungsmodul wird beim Einbau mit dem Gehäuse des Antriebsteils oder auch mit dem Montageblech einer anderen Einheit, beispielsweise der Fahrsteuerung, verbunden.The main electromechanical components of the power supply are thus manufactured as a compact module with a single carrier. The carrier summarizes the components to form a stable unit and can be advantageously designed as a mounting plate to which the components are screwed. The power supply module is connected during installation with the housing of the drive part or with the mounting plate of another unit, such as the driving control.

Der mehrpolige Steckverbinder und die Hochstromanschlüsse sind so an dem Träger angeordnet, dass sie zur Montage des Stromversorgungsmoduls in dem Flurförderzeug leicht zugänglich sind. Die steckbare Sicherung kann zweckmäßigerweise so platziert werden, dass sie auch bei eingebautem Stromversorgungsmodul leicht ausgewechselt werden kann.The multipolar connector and the high current terminals are arranged on the carrier so that they are easily accessible for mounting the power supply module in the truck. The pluggable fuse can conveniently be placed so that it can be easily replaced even with built-in power supply module.

Der Hochstromanschluß für den Anschluß an eine Batterie kann eine einfache Schraubverbindung sein, bevorzugt wird jedoch ein spezieller Batteriestecker verwendet.The high current terminal for connection to a battery may be a simple screw connection, but preferably a special battery connector is used.

Bei der Montage eines Flurförderzeugs werden durch das erfindungsgemäße Stromversorgungsmodul wichtige Vorteile erzielt. So müssen die einzelnen Komponenten nicht über das Flurförderzeug verteilt an unterschiedlichen Orten montiert werden, z.B. auf verschiedenen Platinen oder Montageblechen elektronischer Steuerungen. Zusätzlich ist das Stromversorgungsmodul vormontiert und kann sehr einfach in ein Flurförderzeug eingebaut werden. Es muß dazu lediglich eine Befestigung des Moduls und eine Verbindung mit der Batterie und den Verbrauchern über die vorgesehenen Hochstromanschlüsse sowie mit der Steuerung für das Stromversorgungsmodul über den mehrpoligen Steckverbinder vorgenommen werden. Die vereinfachte Montage ist weniger fehleranfällig, zeit- und kostenaufwenig als die Montage der entsprechenden Komponenten einer herkömmlichen Stromversorgung.When mounting a truck important advantages are achieved by the power supply module according to the invention. Thus, the individual components need not be distributed over the truck at different locations, e.g. on different boards or mounting plates of electronic controls. In addition, the power supply module is pre-assembled and can be easily installed in a truck. It must be made only about a mounting of the module and a connection to the battery and the consumers on the intended high-current connections and with the control for the power supply module via the multi-pin connector. The simplified installation is less error-prone, time and cost consuming than the assembly of the corresponding components of a conventional power supply.

Der Umfang und die Komplexität notwendiger Funktionstests des Flurförderzeugs können durch die Erfindung verringert werden. Insbesondere können Test des Stromversorgungsmoduls bereits vor dessen Einbau in das Flurförderzeug erfolgen. Dabei vereinfacht sich durch den standardisierten Aufbau des Moduls auch die Verbindung mit einem entsprechenden Prüfstand.The scope and complexity of necessary functional tests of the truck can be reduced by the invention. In particular, testing of the power supply module can be carried out before it is installed in the truck. The standardized construction of the module also simplifies the connection to a corresponding test stand.

Zusätzlich kann das Stromversorgungsmodul nach der. Erfindung für unterschiedliche Typen von deichselgeführten Flurförderzeugen eingesetzt werden. Unabhängig von einem bestimmten Flurförderzeugtyp ist vorgesehen, einen einheitlichen Träger zu verwenden. Dadurch werden Skaleneffekte erreicht und die Entwicklung neuer Fahrzeugtypen vereinfacht. Wahlweise kann die elektrische Auslegung der Komponenten, beispielsweise der von dem Schütz schaltbare Maximalstrom, an die individuellen Anforderungen des Flurförderzeugs angepaßt werden.In addition, the power supply module can after the. Invention are used for different types of drawbar guided industrial trucks. Regardless of a specific truck type is intended to use a single carrier. This achieves economies of scale and the development of new vehicle types simplified. Optionally, the electrical design of the components, for example, the switchable by the contactor maximum current can be adapted to the individual requirements of the truck.

In einer bevorzugten Ausgestaltung bildet der Träger ein Gehäuse oder ist in einem separaten Gehäuse angeordnet. Beispielsweise kann der Träger als wannen- oder kastenförmiges Blech ausgeführt und mit einem Deckel versehen werden. Dadurch vereinfacht sich ein Schutz der Komponenten vor Umwelteinflüssen, insbesondere vor Spritz- oder Kondenswasser.In a preferred embodiment, the carrier forms a housing or is arranged in a separate housing. For example, the carrier can be designed as a trough-shaped or box-shaped plate and provided with a lid. This simplifies protection of the components from environmental influences, in particular against sprayed or condensed water.

In einer bevorzugten Ausgestaltung der Erfindung weist das Stromversorgungsmodul eine Not-Aus-Betätigung auf. Die Not-Aus-Betätigung besteht aus einem an dem Träger angeordneten Mechanismus zur Trennung der Kontakte des Schützes, der von außen betätigbar ist. Dazu ist am Träger des Stromversorgungsmoduls z.B. ein verlagerbarer Schieber vorgesehen, der mit einem Knopf, bevorzugt einem Schlagkopf, direkt oder über ein Gestänge verbunden wird. Der Knopf steht aus dem Gehäuse des Flurförderzeugs vor und wirkt über eine mechanische Verbindung auf die Not-Aus-Betätigung.In a preferred embodiment of the invention, the power supply module on an emergency stop operation. The emergency stop operation consists of a arranged on the support mechanism for the separation of the contacts of the contactor, which is actuated from the outside. For this purpose, on the carrier of the power supply module, e.g. provided a displaceable slide, which is connected to a button, preferably a percussion head, directly or via a linkage. The button protrudes from the body of the truck and acts on the emergency stop via a mechanical connection.

Eine Anordnung der Not-Aus-Betätigung in der Nähe des Hauptschützes und eine gemeinsame Montage dieser Komponenten ist besonders günstig, weil sich die mechanische Verbindung dadurch vereinfacht und so auf besonders einfache Weise eine mechanische Trennung der Kontakte des Schützes durch die Not-Aus-Betätigung erreicht wird. Es wird eine robuste und zuverlässige Notabschaltung erreicht.An arrangement of the emergency stop operation in the vicinity of the main contactor and a common installation of these components is particularly advantageous because the mechanical connection is simplified and thus in a particularly simple manner, a mechanical separation of the contacts of the contactor by the emergency stop operation is reached. A robust and reliable emergency shutdown is achieved.

Gemäß einer Ausgestaltung der Erfindung weist das Stromversorgungsmodul einen akustischen Signalgeber auf. Dies kann z.B. eine Hupe oder ein Summer sein. Ein akustischer Signalgeber wird in der Regel in jedem Flurförderzeug benötigt. Vorteilhaft kann er in das erfindungsgemäße Stromversorgungsmodul integriert werden. Der Aufwand für die Montage wird gegenüber einem andernorts separat anzuordnenden akustischen Signalgeber verringert.According to one embodiment of the invention, the power supply module has an acoustic signal generator. This can e.g. to be a horn or a buzzer. An acoustic signal generator is usually required in every truck. Advantageously, it can be integrated into the power supply module according to the invention. The effort for assembly is reduced compared to an elsewhere to be arranged separately acoustic signal generator.

Bevorzugt weist das Stromversorgungsmodul ein zweites Schütz oder einen Steckplatz zur Aufnahme eines zweiten Schützes zur Bestromung eines Hydraulikpumpenmotors bzw. seiner Steuerung auf. Je nach Ausführung des Flurförderzeugs werden der Motor für die Hydraulikpumpe und derjenige für den Fahrantrieb von einer separaten oder einer gemeinsamen elektronischen Steuerung angesteuert. Wenn zwei separate Steuerungen verwendet werden, ist es von Vorteil, ein zweites Schütz für den zweiten Hauptverbraucher einzusetzen. Es ist dann vorgesehen, auch das zweite Schütz in das Stromversorgungsmodul zu integrieren. Das zweite Schütz kann ein fester Bestandteil des Stromversorgungsmoduls sein. In einer Variante ist das Stromversorgungsmodul durch einen entsprechenden Steckplatz für den einfachen Einbau des zweiten Schützes vorbereitet.Preferably, the power supply module has a second contactor or a slot for receiving a second contactor for energizing a hydraulic pump motor or its control. Depending on the design of the truck, the motor for the hydraulic pump and that for the drive are controlled by a separate or a common electronic control. If two separate controllers are used, it is advantageous to use a second contactor for the second main consumer. It is then intended to integrate the second contactor in the power supply module. The second contactor can be an integral part of the power supply module. In one variant, the power supply module is prepared by a corresponding slot for easy installation of the second contactor.

Im Fall einer separaten Bestromung des Hydraulikpumpenmotors bzw. seiner Steuerung ist ein separater Hochstromanschluß dafür vorgesehen. Der Hochstromanschluß ist mit dem zweiten Schütz verbunden und stellt eine einfache Anschlußmöglichkeit für den Hydraulikpumpenmotor bzw. seine Steuerung dar.In the case of a separate energization of the hydraulic pump motor or its control, a separate high-current connection is provided for this purpose. The high current connection is connected to the second contactor and provides a simple connection option for the hydraulic pump motor or its control.

Gemäß einer Ausgestaltung weist das Stromversorgungsmodul einen Hochstromanschluß zum Anschluß eines Batterieladegeräts auf. Diese Verbindungsmöglichkeit der Batterie mit einem Batterieladegerät über das Stromversorgungsmodul ist besonders in Verbindung mit einem in das Flurförderzeug integrierten Batterieladegerät sinnvoll. In diesem Fall verbleibt die Batterie während des Aufladens im Flurförderzeug, so daß sie an die Stromversorgung angeschlossen bleiben kann. Gleichzeitig kann eine Absicherung des Batterieladegeräts in das Stromversorgungsmodul integriert werden.According to one embodiment, the power supply module has a high-current connection for connecting a battery charger. This possibility of connecting the battery to a battery charger via the power supply module is particularly useful in conjunction with a battery charger integrated in the truck. In this case, the battery remains in the truck during charging so that it can remain connected to the power supply. At the same time a fuse of the battery charger can be integrated into the power supply module.

In einer bevorzugten Ausgestaltung der Erfindung sind die Hochstromanschlüsse des Stromversorgungsmoduls als Hochstromschnellverbinderanschlüsse ausgeführt. Die Hochstromschnellverbinderanschlüsse können als Klemm-, Schraub- oder Steckverbinder ausgestaltet sein. Es wird dadurch eine weitere Vereinfachung bei der Montage des Stromversorgungsmoduls ermöglicht. Weiterhin ist vorgesehen, für sämtliche Hochstromanschlüsse die gleiche Art von Hochstromschnellverbinderanschlüssen zu wählen. Dadurch vereinfacht sich bei der Montage des Flurförderzeugs auch die Anfertigung eines Kabelbaums, dessen Anschlüsse mit dem Stromversorgungsmodul zu verbinden sind. Ein Werkzeugwechsel zur Montage der Gegenstücke der Hochstromschnellverbinderanschlüsse des Stromversorgungsmoduls ist dann nicht erforderlich, wodurch Rüstzeiten bei der Montage verkürzt werden können.In a preferred embodiment of the invention, the high current terminals of the power module are designed as high current fast connector terminals.
