Abstract
Description
Die Erfindung bezieht sich auf eine Antriebseinheit nach der im Oberbegriff von Anspruch 1 näher definierten Art.The The invention relates to a drive unit according to the preamble defined by claim 1 in more detail Art.
Gattungsgemäße Antriebseinheiten werden beispielsweise zum Antrieb eines Flurförderzeuges oder in der Lagertechnik verwendet, wobei ein Antriebsmotor ein Fahrzeugrad im Sinne eines Antriebs und ein Lenkmotor das Fahrzeugrad im Sinne einer Lenkbewegung antreiben.Generic drive units For example, to drive a truck or in the warehouse used, wherein a drive motor is a vehicle wheel in the sense of Drive and a steering motor, the vehicle in the sense of a steering movement drive.

Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Antriebseinheit mit einem koaxial angeordneten Fahr- und Lenkmotor zu schaffen, welche ein Fahrzeugrad im Sinne einer Antriebsbewegung und einer Lenkbewegung antreibt, welcher einfach und kostengünstig aufgebaut sein soll.Of the present invention is based on the object, a drive unit with a coaxially arranged driving and steering motor, which a vehicle wheel in the sense of a drive movement and a Steering movement drives, which is simple and inexpensive should be.
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 koaxial angeordneten Lenk- und Fahrmotor auf, wobei zwischen dem Lenk- und Fahrmotor ein Untersetzungsgetriebe angeordnet ist, und der Abtrieb dieses Untersetzungsgetriebes eine Antriebswelle antreibt, welche in einer hohlen Antriebswelle des Fahrmotors angeordnet ist. Dadurch ist es möglich, den Lenkmotor oberhalb des Fahrmotors anzuordnen, wodurch der Antrieb einfach und modular aufgebaut werden kann. Die Antriebswelle des Lenkmotors treibt den Eingang des Untersetzungsgetriebes an, welcher als mehrstufiger Planetentrieb ausgebildet sein kann, es besteht jedoch auch die Möglichkeit, das Untersetzungsgetriebe, welches dem Lenkmotor nachgeschaltet angeordnet ist, als Wolfrom-Getriebe. Cyclo-Getriebe oder Planetengetriebe auszuführen.According to the invention the drive unit has a coaxially arranged steering and drive motor, wherein between the steering and traction motor, a reduction gear is arranged, and the output of this reduction gear a Drive shaft drives, which in a hollow drive shaft of the Drive motor is arranged. This makes it possible to use the steering motor above to arrange the drive motor, making the drive simple and modular can be. The drive shaft of the steering motor drives the entrance of the reduction gear, which as a multi-stage planetary gear can be trained, but there is also the possibility the reduction gear, which downstream of the steering motor is arranged as Wolfrom gear. Cyclo gear or planetary gear perform.
In einer weiteren Ausgestaltungsform ist zwischen diesem Untersetzungsgetriebe und dem Antriebsmotor eine Bremse angeordnet, welche die Antriebswelle des Antriebsmotors gegenüber dem Gehäuse bremst. Es besteht auch die Möglichkeit, die Bremse im Bereich des Antriebsmotors, entgegengesetzt dem Untersetzungsgetriebe zwischen dem Anriebsmotor und dem Lenkmotor, anzuordnen. Die Bremse ist dann im Bereich des Lagers, über welches sich das Fahrzeugrad zum Gehäuse der Motore verdrehen kann, angeordnet. Durch diesen Aufbau ist es möglich, den Fahrmotor, die Bremse, das Lenkgetriebe und den Lenkmotor koaxial anzuordnen, wodurch sich der radiale Bauraum verringert.In Another embodiment is between this reduction gear and the drive motor is arranged a brake which the drive shaft the drive motor opposite the housing slows. There is also the possibility the brake in the area of the drive motor, opposite to the reduction gear between the drive motor and the steering motor to arrange. The brake is then in the area of the camp, over which the vehicle wheel can twist to the housing of the motors, arranged. With this construction, it is possible, the drive motor, the brake, to arrange the steering gear and the steering motor coaxial, resulting in reduces the radial space.
In einer weiteren Ausgestaltungsform ist das Lenkgetriebe mit einem Lebensdauer-Schmiermittel versehen, wodurch sich die Wartung des Antriebs erheblich reduziert. Durch die Verwendung von bürstenlosen Gleich- oder Wechselstrommotoren in Standard- oder Scheibenläufer-Ausführung läßt sich die Wartung des Antriebs weiter verringern.In Another embodiment is the steering gear with a Lifetime lubricant provided, which improves the maintenance of the Drive significantly reduced. By using brushless DC or AC motors in standard or disc rotor design can be further reduce the maintenance of the drive.
In einer weiteren Ausgestaltungsform der Erfindung ist das Gehäuse, welches die Bremse beinhaltet, gleichzeitig als Lagerschild des Fahrmotors ausgebildet. Je nach Anordnung der Bremse ist es das Schild im Bereich des Lenkgetriebes oder im Bereich des Stirnradgetriebes. Die Bremse ist vorteilhaft als Negativ-Bremse ausgebildet, d. h., die Bremse wird mit Federkraft im Schließsinne und elektrisch oder hydraulisch im Öffnungssinne betätigt. Hierbei besteht die Möglichkeit, die Bremse als naß- oder trockenlaufende Bremse auszuführen.In Another embodiment of the invention is the housing, which the brake includes, at the same time designed as a bearing plate of the drive motor. Depending on the arrangement of the brake, it is the shield in the region of the steering gear or in the area of the spur gear. The brake is advantageous as Negative brake formed, d. h., the brake is with spring force in the closing sense and operated electrically or hydraulically in the opening direction. This consists the possibility, the brake as wet or dry-running brake.
