Abstract

Es wird ein Laderfahrzeug beschrieben mit einem Hubarm (18), dessen hinterer Bereich (34) mittels einer Lenkeranordnung (20) an dem Fahrzeug (10) angelenkt ist und an dessen vorderem Bereich (22) eine durch den Hubarm (18) anhebbare Schaufel (16) befestigt ist. Die Lenkeranordnung (20) weist wenigstens einen oberen Lenker (26) und einen unteren Lenker (28) auf. Der obere Lenker (26) ist einenends am Fahrzeug (10) und anderenends im hinteren Bereich (34) des Hubarms (18) angelenkt und erstreckt sich bei abgesenktem Hubarm (18) ausgehend von der fahrzeugseitigen Anlenkstelle (K) im wesentlichen schräg nach hinten und unten.A loader vehicle with a lifting arm (18) is described, the rear area (34) thereof by means of a handlebar arrangement (20) is articulated on the vehicle (10) and on its front Area (22) a blade (16) which can be raised by the lifting arm (18) is attached. The handlebar arrangement (20) has at least one upper link (26) and a lower link (28). The upper Handlebar (26) is at one end of the vehicle (10) and at the other end in rear region (34) of the lifting arm (18) articulated and extends with the lifting arm (18) lowered starting from the vehicle-side articulation point (K) essentially obliquely behind and below.

Zur Verbesserung der Hubbahn der Schaufel (16), die eine einfachere Handhabung des Laderfahrzeugs (10) erlaubt und einen stabilen Fahrzeugbetrieb mit sich bringt, wird vorgeschlagen, den oberen Lenker (26) in einem oberen, hinteren Bereich (42) des Fahrzeugs (10) anzulenken. Wegen der dadurch möglichen relativ steilen Ausrichtung des oberen Lenkers (26) ergibt sich eine im unteren Hubbereich senkrechte Hubbahn der Schaufel (16), die im oberen Hubbereich nach vorn wandert und bei der maximalen Hubhöhe die am weitesten vorn liegende Position einnimmt.

Figure 00000001
In order to improve the stroke path of the bucket (16), which allows easier handling of the loader vehicle (10) and brings about stable vehicle operation, it is proposed that the upper link (26) be placed in an upper, rear area (42) of the vehicle (10 ) to link. Because of the relatively steep alignment of the upper link (26) which is possible as a result, there is a vertical stroke path of the blade (16) in the lower stroke area, which moves forward in the upper stroke area and occupies the most forward position at the maximum stroke height.
