Abstract
Description
Die Erfindung betrifft eine Antriebseinheit nach der im Oberbegriff von Anspruch 1 näher definierten Art.The The invention relates to a drive unit according to the preamble of claim 1 closer defined type.
Gattungsgemäße Antriebseinheiten werden häufig als Kompaktantriebe bezeichnet und weisen einen elektrischen Fahrmotor und einen elektrischen Lenkmotor auf, um ein Fahrzeugrad im Sinne einer Antriebsbewegung und einer Lenkbewegung anzutreiben.Generic drive units become common referred to as compact drives and have an electric traction motor and an electric steering motor on to a vehicle wheel in the sense to drive a drive movement and a steering movement.
Diese Antriebe werden vorzugsweise für elektrisch angetriebene Fahrzeuge, wie beispielsweise Flurförderzeuge, verwendet.These Drives are preferably for electrical driven vehicles, such as trucks used.
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Antriebseinheit mit einem Fahrmotor und einem Lenkmotor zu schaffen, welche insbesondere in ihrer vertikalen Erstreckung kompakt bauend ausgeführt ist und das Fahrzeugrad über eine Bremse bremsbar ist.Of the present invention is based on the object, a drive unit to provide with a traction motor and a steering motor, which in particular in its vertical extension is designed to be compact and the vehicle wheel over a brake is brakable.
Die Aufgabe wird mit einer, auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden, gattungsgemäßen Antriebseinheit gelöst.The Task is with a, even the characterizing features of the main claim having, generic drive unit solved.
Erfindungsgemäß weist die Antriebseinheit einen Fahrmotor und einen Lenkmotor auf, wobei der Fahrmotor über eine Bremse mit einer elektromagne tischen Betätigungseinrichtung bremsbar und die Bremse unmittelbar benachbart zum Fahrmotor angeordnet ist. Die Bremse kann entweder im stromlosen Zustand geschlossen oder als Bremse ausgeführt sein, welche im stromlosen Zustand geöffnet ist.According to the invention the drive unit on a traction motor and a steering motor, wherein the traction motor over a brake braked with an electromagnetic actuating device and the brake is disposed immediately adjacent to the traction motor. The brake can either be closed when de-energized or designed as a brake be, which is open when de-energized.
In einer weiteren Ausgestaltungsform der Erfindung ist das Lagerschild des Fahrmotors aus einem magnetisch leitenden Werkstoff ausgebildet und mit der elektromagnetischen Betätigungseinrichtung der Bremse so verbunden, dass bei Betätigung der elektromagnetischen Bremseinrichtung die Bremse im Öffnungssinne betätigt wird. Dadurch ist es möglich, die Wicklung der Betätigungseinrichtung der Bremse direkt in das Lagerschild einzusetzen, so dass diese Wicklung mit isolierendem Material umgeben sein kann, welches vorzugsweise über einen Spritzvorgang oder durch druckloses Vergießen aufgebracht wird. Der Werkstoff ist elektrisch isolierend und magnetisch neutral ausgeführt. Um den Streufluß einzudämmen, besteht die Möglichkeit, begrenzende Schichten im Lagerschild oder unmittelbar angrenzend zum Lagerschild aus einem nichtmagnetischen Werkstoff auszubilden.In Another embodiment of the invention is the end shield the driving motor formed of a magnetically conductive material and with the electromagnetic actuator of the brake connected so that when pressed the electromagnetic brake device, the brake in the opening direction actuated becomes. This makes it possible the winding of the actuator insert the brake directly into the end shield, so that this Winding can be surrounded with insulating material, which preferably via an injection process or by pressureless casting is applied. The material is electrically insulating and magnetic neutral. To contain the stray flux exists the possibility, limiting layers in the end shield or immediately adjacent to form the bearing plate of a non-magnetic material.
In einer weiteren Ausgestaltungsform der Erfindung steht die Antriebswelle des Fahrmotors mit einer Bremse mit einer Betätigungseinrichtung in Wirkverbindung, welche beispielsweise als Standardbremse ausgeführt sein kann, und unmittelbar benachbart zum Lagerschild des Fahrmotors angeordnet ist. Der Lagerschild des Fahrmotors ist dabei so ausgebildet, dass er eine topfförmige Vertiefung aufweist, in welcher die Bremse, zumindest teilweise, integriert angeordnet sein kann.In Another embodiment of the invention is the drive shaft the traction motor with a brake with an actuating device in operative connection, which can be designed, for example, as a standard brake, and immediately adjacent is arranged to the end plate of the drive motor. The end shield of the Driving motor is designed so that it has a cup-shaped depression, in which the brake, at least partially, integrated can be.
In einer weiteren Ausgestaltungsform der Erfindung ist hierbei die Wicklung des Fahrmotors so ausgebildet, dass der Innendurchmesser der Wickelköpfe des Fahrmotors so groß ist, dass die Bremse und die topfförmige Umrandung der Bremse, welche durch einen Teil des Lagerschilds gebildet wird, zwischen diesen Wickelköpfen angeordnet sein kann.In Another embodiment of the invention is the Winding the traction motor so formed that the inner diameter the winding heads the drive motor is so big that the brake and the cup-shaped Border of the brake, which is formed by a part of the end shield will, between these windings can be arranged.
In einer weiteren Ausgestaltungsform der Erfindung sind der Lenkmotor und der Fahrmotor koaxial zueinander angeordnet, wobei der Lenkmotor, zumindest teilweise, im Bereich der Wicklung des Fahrmotors angeordnet sein kann. Der Lenkmotor weist hierbei eine Hohlwelle auf, in welcher die Antriebswelle des Fahrmotors angeordnet ist.In Another embodiment of the invention are the steering motor and the traction motor arranged coaxially with each other, wherein the steering motor, at least partially, be arranged in the region of the winding of the drive motor can. The steering motor in this case has a hollow shaft, in which the drive shaft of the drive motor is arranged.
In einer weiteren Ausgestaltungsform der Erfindung weist die Bremse eine zentrische Bohrung auf, durch welche die Antriebswelle des Fahrmotors ragen kann, um ein Lüfterrad anzutreiben.In Another embodiment of the invention has the brake a central bore through which the drive shaft of the Driving motor can protrude to a fan drive.
In einer weiteren Ausgestaltungsform der Erfindung ist eine elektronische Steuereinheit unmittelbar benachbart zur Bremse angeordnet, wobei die Bremse eine zentrische Öffnung aufweist, durch welche die Antriebswelle des Fahrmotors ragt, um einen mit der Antriebswelle in Wirkverbindung stehenden Sensor zwischen elektronischer Steuereinheit und Antriebswelle des Fahrmotors anzuordnen, wobei die elektronische Steuereinheit die Signale dieses Sensors, beispielsweise zur Drehzahlbestimmung des Antriebsmotors, verwendet.In Another embodiment of the invention is an electronic Control unit disposed immediately adjacent to the brake, wherein the brake has a centric opening has, through which the drive shaft of the drive motor projects to a sensor operatively connected to the drive shaft to arrange electronic control unit and drive shaft of the drive motor, wherein the electronic control unit receives the signals of this sensor, For example, to determine the speed of the drive motor used.
In einer weiteren Ausgestaltungsform der Erfindung ist eine weitere elektronische Steuereinheit benachbart zum Lenkmotor angeordnet, welche den Lenkmotor steuert.In Another embodiment of the invention is another electronic control unit arranged adjacent to the steering motor, which controls the steering motor.
