Description

Hydraulische Kippvorrichtung für Wagenkasten, insbesondere von Kraftfahrzeugen Die Erfindung betrifft eine hydraulische Kippvorrichtung für Wagenkasten, insbesondere von Kraftfahrzeugen, mit einem in der Längsmittelebene des Fahrzeugs liegenden wagerechten Druckzylinder, dessen Druckglied gegen eine oder mehrere Kurvenbahnen an der Unterseite einer am hinteren Ende des Fahrgestells schwenkbar gelagerten, sich mit ihrem vorderen Ende gegen die Unterfläche des Kastens legenden Wiege wirkt. Das Neue besteht in einer solchen Ausbildung der Kurvenbahn oder -bahnen, daß gleichen zurückgelegten wagerechten Wegstrecken des auf sie wirkenden Druckgliedes gleiche oder annähernd gleiche senkrechte Projektionsstrecken der dabei von dem Schwerpunkt der Last zurückgelegten Bahnstrecken entsprechen. Hierdurch wird erreicht, daß die Kraft des auf die Wiege wirkenden Druckgliedes und damit die Drücke im Druckzylinder während des ganzen Hubes angenähert konstant bleiben, ünd daß die maximalen Drücke herabgesetzt werden. Die Folge ist ein besserer Wirkungsgrad und eine Verringerung der Beanspruchungen sämtlicher Teile.Hydraulic tipping device for car bodies, in particular for motor vehicles The invention relates to a hydraulic tipping device for car bodies, in particular of motor vehicles, with a horizontal plane lying in the longitudinal center plane of the vehicle Pressure cylinder, the pressure member of which against one or more cam tracks on the underside one at the rear end of the chassis pivotably mounted to its front The end of the cradle placed against the lower surface of the box acts. The new consists in such a design of the curved path or paths that the same covered horizontal stretches of the pressure member acting on them the same or approximately the same vertical projection distances as those covered by the center of gravity of the load Correspond to railway lines. This ensures that the power of the on the cradle acting pressure member and thus the pressures in the pressure cylinder during the whole Stroke remain approximately constant, and that the maximum pressures are reduced. The result is a better degree of efficiency and a reduction in stresses all parts.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung schematisch. Der Wagenkasten i wird mit Hilfe eines in der Längsmittelebene des Fahrgestells 2 liegenden wagerechten, hydraulischen Druckzylinders 3 gekippt, dessen Kolbenstange 4 mittels einer Druckrolle 5 auf eine am hinteren Ende des Fahrgestells um eine Querachse 6 schwenkbare Wiege wirkt. Vorzugsweise trägt zu diesem Zweck das Ende der Kolbenstange 4 .eine Querachse, an deren beiden seitlichen Enden je eine Rolle 5 sitzt, die auf Gleitbahnen 7 auf dem Fahrgestell läuft. Die beiden Rollen 5 wirken gegen zwei symmetrische Kurvenbahnen 8 an der Unterseite der Wiege, die ihrerseits mit einer Kugel 9 gegen die Unterfläche des um die Achse io schwenkbaren Wagenkastens i, diesen anhebend, drückt. Wie aus der Zeichnung ersichtlich, ist die Gestalt der Kurvenbahnen, die naturgemäß auch durch eine einzige ersetzt werden können, erfindungsgemäß so gewählt, daß gleichen wagerechten Wegstrecken a der Druckrolle 5 bzw. des sie antreibenden, im Druckzylinder 3 liegenden Kolbens gleiche senkrechte Projektionsstrecken b der beim Heben von dem Schwerpunkt i i des Wagenkastens i zurückgelegten Bahnstrecken entsprechen.The drawing illustrates an embodiment of the invention schematic. The car body i is with the help of a in the longitudinal center plane of the Chassis 2 lying horizontal, hydraulic pressure cylinder 3 tilted, its Piston rod 4 by means of a pressure roller 5 on one at the rear end of the chassis cradle pivotable about a transverse axis 6 acts. Preferably contributes to this end the end of the piston rod 4 .eine transverse axis, each at the two lateral ends a roller 5 sits, which runs on slideways 7 on the chassis. The two Rollers 5 act against two symmetrical curved tracks 8 on the underside of the cradle, which in turn with a ball 9 against the lower surface of the pivotable about the axis io Car body i, lifting it, pushes. As can be seen from the drawing, is the shape of the cam tracks, which are naturally also replaced by a single one can, according to the invention so chosen that the same horizontal distances a of the pressure roller 5 or the piston driving it, located in the pressure cylinder 3, is the same vertical Projection distances b when lifting from the center of gravity i i of the car body i correspond to the railway lines covered.
