Description

Die Erfindung betrifft eine mit einem Arbeitsgerät ausgestattete Schaufel für ein Ladefahrzeug.The invention relates to a working device equipped with a bucket for a loading vehicle.

Herkömmliche Ladefahrzeuge, beispielsweise Radlader, können mit verschiedenen Arten von Schaufeln versehen werden. Beispielsweise können solche Schaufeln für Ladefahrzeuge ein Arbeitsgerät aufweisen, wie beispielsweise einen Niederhalter oder eine Ladezange.Conventional loading vehicles, such as wheel loaders, can be provided with different types of blades. For example, such buckets for loading vehicles may have a working device, such as a hold-down or a loading tongs.

Beim Arbeiten mit derartigen Schaufeln werden dann die Arbeitsgeräte relativ zur Schaufel bewegt, insbesondere geschwenkt.When working with such blades then the implements are moved relative to the blade, in particular pivoted.

Bei bekannten Ladefahrzeugen werden hierfür ein oder mehrere Hydraulikzylinder verwendet. Diese Hydraulikzylinder sind an der Schaufel bzw. dem Arbeitsgerät befestigt. Ein Nachteil derartiger Hydraulikzylinder besteht darin, dass sie ständig, einsatzbedingt starken Belastungen durch Staub, Schmutz, Feuchtigkeit und nicht selten der Gefahr der Beschädigung ausgesetzt sind. Entsprechend groß ist der Verschleiß der freiliegenden Gleitflächen und der Dichtungen der Hydraulikzylinder sowie der Aufwand für Wartung und Reparatur.In known loading vehicles one or more hydraulic cylinders are used for this purpose. These hydraulic cylinders are attached to the bucket or implement. A disadvantage of such hydraulic cylinders is that they are constantly exposed to heavy loads due to dust, dirt, moisture and often the risk of damage. The wear of the exposed sliding surfaces and the seals of the hydraulic cylinders as well as the expense of maintenance and repair are correspondingly high.

Angesichts dessen liegt der Erfindung die Aufgabe zugrunde, eine mit einem Arbeitsgerät ausgestattete Schaufel für ein Ladefahrzeug bereitzustellen, die einen geringeren Verschleiß aufweist. Diese Aufgabe wird gelöst durch eine Schaufel gemäß Anspruch 1.In view of this, the present invention seeks to provide a scoop equipped with a working device for a loading vehicle, which has a lower wear. This object is achieved by a blade according to claim 1.

Erfindungsgemäß wird eine Schaufel für ein Ladefahrzeug, ausgestattet mit einem Arbeitsgerät, bereitgestellt, wobei die Schaufel einen Drehmotor aufweist.According to the invention, a bucket is provided for a loading vehicle equipped with a working device, the bucket having a rotary motor.

Aufgrund ihres abgeschlossenen Aufbaus sind Drehmotoren und damit auch entsprechend ausgerüstete Schaufeln unempfindlich gegen die bei üblichen Einsatzbedingungen auftretenden Belastungen, wie Staub, Schmutz, Feuchtigkeit sowie gegen Beschädigung. Entsprechend geringer ist der Verschleiß der Drehmotoren und der Aufwand für Reparaturen. Der Platzbedarf ist bei den sehr kompakt bauenden Drehmotoren sehr gering. Weiterhin kann durch den Drehmotor ein gleichbleibendes Drehmoment beim Öffnen und Schließen der Schaufel ermöglicht werden.Due to their closed structure, rotary motors and thus appropriately equipped blades are insensitive to the stresses occurring under normal conditions of use, such as dust, dirt, moisture and damage. Correspondingly lower is the wear of the rotary motors and the expense of repairs. The space requirement is very low in the very compact design rotary motors. Furthermore, a constant torque during opening and closing of the blade can be made possible by the rotary motor.

Die Schaufel und das Arbeitsgerät können jeweils mit dem Drehmotor verbunden sein. Insbesondere kann der Drehmotor fest mit der Schaufel und/oder dem Arbeitsgerät verbunden sein. Der Drehmotor kann dabei insbesondere drehfest mit der Schaufel und/oder dem Arbeitsgerät verbunden sein. Auf diese Weise lässt sich auch der Verschleiß von Zu- und Ableitungen zum Drehmotor verringern.The bucket and the implement may each be connected to the rotary motor. In particular, the rotary motor can be firmly connected to the blade and / or the implement. The rotary motor can be connected in particular rotationally fixed to the blade and / or the implement. In this way, the wear of supply and discharge lines to the rotary motor can be reduced.

Bei herkömmlichen Hydraulikzylindern bewegen sich aufgrund der Zylinder die entsprechenden Hydraulikleitungen, sodass es insbesondere zu einem Verschleiß aufgrund Scheuerns kommen kann, was bei den beschriebenen, mit der Schaufel bzw. dem Arbeitsgerät verbundenen Drehmotoren nicht der Fall ist.In conventional hydraulic cylinders move due to the cylinders, the corresponding hydraulic lines, so in particular it can come to wear due to scrubbing, which is not the case in the described, associated with the blade or the implement rotary motors.

Der Drehmotor kann insbesondere lösbar, beispielsweise mittels Schrauben, oder unlösbar, beispielsweise mittels Schweißen oder Nieten, mit der Schaufel und/oder dem Arbeitsgerät verbunden sein. Das Arbeitsgerät kann insbesondere über den Drehmotor oder mittels des Drehmotors mit der Schaufel verbunden sein.The rotary motor can in particular be detachably connected, for example by means of screws, or non-detachably, for example by means of welding or riveting, to the blade and / or the implement. The working device can be connected in particular via the rotary motor or by means of the rotary motor with the blade.

Bei den zuvor beschriebenen Schaufeln kann der Drehmotor die Schaufel und das Arbeitsgerät relativ zueinander bewegen. Der Drehmotor kann mit anderen Worten derart angeordnet sein, dass durch ihn die Schaufel und das Arbeitsgerät relativ zueinander bewegbar sind.In the above-described blades, the rotary motor can move the bucket and the implement relative to each other. In other words, the rotary motor can be arranged such that the blade and the implement can be moved relative to one another through it.

Das Arbeitsgerät kann insbesondere ein Niederhalter, eine Ladezange, eine Greifgabel, ein Trägerrahmen oder ein Klappteil sein. Bei dem Trägerrahmen kann es sich um einen Trägerrahmen für die Schaufel handeln.The implement may in particular be a hold-down device, a loading tongs, a gripping fork, a support frame or a folding part. The support frame may be a support frame for the bucket.

Der Drehmotor kann hydraulisch und/oder pneumatisch und/oder elektrisch angetrieben werden. Der Drehmotor kann hydraulisch und/oder pneumatisch und/oder elektrisch gesteuert werden.The rotary motor can be driven hydraulically and / or pneumatically and / or electrically. The rotary motor can be controlled hydraulically and / or pneumatically and / or electrically.

Bei den zuvor beschriebenen Schaufeln kann es sich insbesondere um eine Hochkippschaufel, eine Seitenkippschaufel, eine Ladegabel mit Niederhalter, eine Niederhalterschaufel oder eine Klappschaufel, insbesondere eine 4-in-1-Schaufel, handeln.The blades described above may in particular be a high-tilt bucket, a side-tipper bucket, a loading fork with hold-down device, a hold-down bucket or a folding bucket, in particular a 4-in-1 bucket.

Das Arbeitsgerät kann bezüglich der Schaufel um eine Schwenkachse schwenkbar sein. Dabei kann der Drehmotor koaxial und/oder in Verlängerung zu der Schwenkachse angeordnet sein. Die Antriebswelle des Drehmotors kann koaxial zu der Schwenkachse angeordnet sein. Dies erlaubt insbesondere eine kompakte Anordnung des Drehmotors an der Schaufel. Der Drehmotor kann beispielsweise in der Schaufel integriert bzw. innerhalb der Schaufel angeordnet sein.The implement may be pivotable about a pivot axis with respect to the bucket. In this case, the rotary motor can be arranged coaxially and / or in extension to the pivot axis. The drive shaft of the rotary motor can be arranged coaxially with the pivot axis. This allows in particular a compact arrangement of the rotary motor on the Shovel. The rotary motor can for example be integrated in the blade or arranged inside the blade.

Die zuvor beschriebenen Schaufeln können insbesondere mehr als einen Drehmotor umfassen. Dabei kann dann beispielsweise das Arbeitsgerät bezüglich der Schaufel um mehr als eine Schwenkachse schwenkbar sein und die Antriebswelle jeweils eines Drehmotors koaxial zu einer der Schwenkachsen angeordnet sein.The blades described above may in particular comprise more than one rotary motor. In this case, for example, the implement with respect to the blade can be pivoted about more than one pivot axis and the drive shaft in each case a rotary motor can be arranged coaxially to one of the pivot axes.

Die Erfindung stellt weiterhin ein Ladefahrzeug umfassend eine der zuvor beschriebenen Schaufeln bereit. Das Ladefahrzeug kann insbesondere ein Frontlader, ein Teleskoplader oder ein Radlader sein.The invention further provides a loading vehicle comprising one of the previously described blades. The loading vehicle may in particular be a front loader, a telescopic loader or a wheel loader.

Weiterhin stellt die Erfindung die Verwendung eines Drehmotors für eine mit einem Arbeitsgerät ausgestattete Schaufel für ein Ladefahrzeug bereit. Bei der Schaufel kann es sich insbesondere um eine der zuvor beschriebenen Schaufeln handeln. So können die Schaufel und das Arbeitsgerät beispielsweise jeweils mit dem Drehmotor verbunden sein.Furthermore, the invention provides the use of a rotary motor for a work tool-equipped bucket for a loading vehicle. The blade may in particular be one of the previously described blades. For example, the bucket and the implement may each be connected to the rotary motor.

Zusätzlich stellt die Erfindung die Verwendung einer der zuvor beschriebenen Schaufeln für ein Ladefahrzeug, insbesondere einen Frontlader, einen Teleskoplader oder ein Radlader bereit.In addition, the invention provides the use of any of the previously described buckets for a loading vehicle, in particular a front loader, a telescopic loader or a wheel loader.
