Abstract

The device has a hydraulic system, to move the bumper forward. The front panel (2) is moved outwards together with the bumper (5). The front panel is vertical when in its normal position, but slopes backwards when extended forward.

Description

Die Erfindung betrifft eine Frontschutzanordnung für Lastwagen und Omnibusse mit einer Hydraulik, durch welche die mittels Schiene verschiebliche Stoßstange nach vorn ausfahrbar ist.The invention relates to a front protection arrangement for trucks and buses with a hydraulic system, through which the means Rail sliding bumper is extendable forward.

Es ist bekannt, Fahrzeugstoßstangen längsbeweglich, nach vorn ausfahrbar und stoßverzehrend anzuordnen. (GB 2084944 und US 4961603 sowie ältere DE 42 39 120 A1). Der Luftwiderstand wird bei den bekannten Anordnungen im ausgefahrenem Zustand der Stoßstange nicht verbessert.It is known to move vehicle bumpers longitudinally, forward extendable and shock-absorbing. (GB 2084944 and US 4961603 and older DE 42 39 120 A1). The air resistance will in the known arrangements in the extended state of the Bumper not improved.

Der Erfindung liegt die Aufgabe zugrunde, Fahrzeugfronten, d. h. die Fahrerkabine besser gegen Aufprall zu schützen und gleich­ zeitig den Luftwiderstand zu verringern, was eine Reduzierung des Treibstoffverbrauches mit sich bringt. Die Erfindung be­ steht darin, daß die Fronthaube zusammen mit der Stoßstange nach vorn ausfahrbar ist, derart, daß die zunächst senkrechte Fronthaube im nach vorn ausgefahrenen Zustand nach hinten ge­ neigt ist.The invention has for its object vehicle fronts, d. H. to better protect the driver's cab against impact and the same to reduce air resistance early, which is a reduction of fuel consumption. The invention be is that the front hood together with the bumper is extendable to the front, such that the initially vertical Front hood extended to the rear when extended tends.

Ein Ausführungsbeispiel der Erfindung ist nachstehend anhand der Zeichnung beschrieben.An embodiment of the invention is shown below described the drawing.

Fig. 1 zeigt in schematischer Darstellung die Seitenansicht der Front eines Lastwagens oder Omnibusses mit geschlossener Front­ haube. Fig. 1 shows a schematic representation of the side view of the front of a truck or bus with the front hood closed.

Fig. 2 zeigt die Anordnung nach Fig. 1 bei nach vorn ausgefahre­ ner Fronthaube. Fig. 2 shows the arrangement of FIG. 1 with the front hood extended ner.

Wie aus Fig. 1 und Fig. 2 ersichtlich, wird durch die Hydraulik 1 (Hydraulikaggregat) die an der Schiene 4 montierte Stoßstange 5 während der Fahrt nach vorn ausgefahren. Feste Vorrichtungsge­ häuse sind mit 3 bezeichnet. Die dabei herausgezogene Front­ haube 2 wird, wie aus Fig. 2 ersichtlich, gleichzeitig nach hin­ ten geneigt.As shown in FIG. 1 and FIG. 2, 1 (hydraulic unit) is extended, the rail 4 mounted on the bumper 5 during travel forward by the hydraulic system. Fixed Vorrichtungsge housing are designated 3 . The front hood 2 pulled out, as shown in FIG. 2, is simultaneously inclined towards th.
