Abstract
Description
Die vorliegende Erfindung betrifft ein Flurförderzeug mit einem elektrischen Energiespeicher für einen elektromotorischen Antrieb und für eine elektrische Bremse.The present invention relates to an industrial truck with an electrical energy storage for an electromotive Drive and for an electric brake.
Bei herkömmlichen hydraulischen Bremssystemen kann jederzeit über eine mechanische Kupplung zwischen Bremspedal und Hauptbremszylinder eine Kraft ausgeübt werden, die einen Druck im Hydrauliksystem aufbaut und in einem Bremszylinder eine Kraft auf Bremsbacken oder Belege ausübt. Bei Ausfall der Bordspannung bei dem Flurförderzeug und dem damit verbundenen Aussetzen des Bremskraftverstärkers kann noch eine gewisse Verzögerung über das Bremspedal erzeugt werden.With conventional hydraulic brake systems can at any time a mechanical clutch between the brake pedal and master brake cylinder exerted a force that builds up pressure in the hydraulic system and in one Brake cylinder exerts a force on brake shoes or pads. In the event of failure the on-board voltage in the industrial truck and the associated suspension of the brake booster can some delay about that Brake pedal are generated.
Im Gegensatz zu dem bekannten System auf hydraulischer Basis hat bei einem elektrischen System der Ausfall der Bordspannung den Verlust eines Großteils der Bremsenergie zur Folge. Lediglich mit einigen speziell aufgebauten Bremsen, wie beispielsweise Federkraft belastete, stromlos betätigte Bremsen kann noch eine geringe Verzögerung erzielt werden.In contrast to the known system on a hydraulic basis there is a failure in an electrical system the loss of a large part of the braking energy Episode. Only with some specially designed brakes, such as Spring-loaded, de-energized brakes can do one more little delay be achieved.
Aus
Der Erfindung liegt die Aufgabe zugrunde, ein Flurförderzeug bereitzustellen, das mit einfachen Mitteln eine Möglichkeit schafft, auch bei Ausfall der elektrischen Versorgung das Flurförderzeug mit einer elektrischen Bremse geregelt abzubremsen.The invention is based on the object Truck provide that with simple means one way manages the industrial truck even if the electrical supply fails controlled braking with an electric brake.
Erfindungsgemäß wird die Aufgabe durch ein Flurförderzeug mit den Merkmalen aus Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen bilden den Gegenstand der Unteransprüche.According to the invention, the object is achieved by a Truck solved with the features of claim 1. Advantageous configurations form the subject of the subclaims.
Das erfindungsgemäße Flurförderzeug besitzt einen elektrischen Energiespeicher zur Versorgung des elektromotorischen Antriebs und einer elektrischen Bremse mit elektrischer Energie. Erfindungsgemäß ist zusätzlich ein Notenergiespeicher zur Versorgung der elektrischen Bremse im Notfall vorgesehen. Bei einem Ausfall oder Unterbrechung der elektrischen Energieversorgung wird die elektrische Bremse durch den Notenergiespeicher versorgt. Ein Fahrer kann somit geregelt das Fahrzeug abbremsen.The industrial truck according to the invention has an electrical Energy storage for supplying the electric motor drive and an electrical brake with electrical energy. According to the invention is also a Emergency energy storage is provided to supply the electric brake in an emergency. In the event of a failure or interruption of the electrical power supply the electric brake is supplied by the emergency energy storage. A driver can thus brake the vehicle in a controlled manner.
In einer bevorzugten Ausgestaltung wird der Fahrmotor in einen generatorischen Betrieb umgeschaltet. Die generatorisch gewonnene Energie wird für den Notenergiespeicher und/oder die elektrische Bremse bereitgestellt. Im Gegensatz zu der bekannten Lösung wird also nicht die Hauptenergieversorgung durch die generatorisch gewonnene Energie ersetzt, sondern es wird die elektrische Bremseinheit über einen Notenergiespeicher versorgt, der bevorzugt durch die generatorisch gewonnene Energie unterstützt wird. Hierbei versorgen Notenergiespeicher und generatorisch gewonnene Energie parallel die Bremseinrichtung, um dem Fahrer ein Abbremsen zu gestatten. Als besonderer Vorteil ergibt es sich, daß der durch die generatorisch erzeugte Energie unterstützte Notenergiespeicher vergleichsweise gering und kostengünstig ausgelegt werden kann.In a preferred embodiment the drive motor is switched to generator operation. The generated energy is used for the emergency energy storage and / or the electric brake is provided. In contrast to the known one solution will not be the main energy supply through the generator gained energy replaced, but it is the electric brake unit over a Emergency energy storage, which is preferred by the generator gained energy supports becomes. In this case, note energy stores and those obtained by generator supply Energy is applied in parallel to the braking device to slow the driver down to allow. A particular advantage is that the through the generator-generated energy supports emergency energy storage comparatively low and inexpensive can be interpreted.
In einer Weiterführung ist eine elektrische Schaltung vorgesehen, die für die generatorisch gewonnene Energie eine Verbindung zur elektrischen Bremseinheit herstellt. Die Schaltung stellt sicher, daß die durch den als Generator betriebenen Antriebsmotor gewonnene Energie zur Bremseinrichtung geleitet wird und dieser zur Verfügung steht. Bevorzugt besitzt der Notenergiespeicher einen Kondensator und/oder einen Akkumulator.In a continuation is an electrical circuit provided for the energy generated by the generator connects to the electrical braking unit manufactures. The circuit ensures that the by the generator powered drive motor gained energy to the braking device is managed and this is available. Preferably owns the emergency energy storage is a capacitor and / or an accumulator.
In einer bevorzugten Ausgestaltung ist der Notenergiespeicher derart ausgelegt, daß ein mit Nennlast beladendes Fahrzeug einmal von maximaler Fahrgeschwindigkeit bis zum Stand abgebremst werden kann. Bei einer noch geringeren Auslegung des Notenergiespeichers wird die während des Bremsvorgangs erzeugte elektrische Energie berücksichtigt, so daß der Notenergiespeicher lediglich zusammen mit der generatorisch erzeugten Energie ausreicht, um das Fahrzeug zu bremsen.In a preferred embodiment the emergency energy storage is designed in such a way that a load with nominal load Vehicle once from maximum driving speed to standstill can be slowed down. With an even smaller interpretation of the Note energy storage is the during electrical energy generated during the braking process is taken into account, so that the Emergency energy storage only together with the generator generated There is enough energy to brake the vehicle.
Der erfindungsgemäße Aufbau wird anhand der nachfolgenden Figuren näher erläutert. Es zeigt:The structure according to the invention is based on the following Figures closer explained. It shows:

Alternativ zu dem Kondensator als Notenergiespeicher kann auch ein Akkumulator als Notenergiespeicher eingesetzt werden. Im Gegensatz zu dem Kondensator treten bei einem Akkumulator keine Einschalt-Spannungsspitzen auf. Der Akkumulator wird zusammen mit einem Laderegler in den Schaltkreis integriert.Alternatively to the capacitor as Emergency energy storage can also be an accumulator as an emergency energy storage be used. In contrast to the capacitor occur at one Accumulator has no switch-on voltage peaks. The accumulator is integrated into the circuit together with a charge controller.
