DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a mounting device for a hydraulically actuated tailgate of a truck, having a transverse support for the tailgate adapted to be mounted at the rear of the vehicular frame and on which are provided, spaced from each other symmetrically relative to the center plane of the vehicle, support flanges provided with through-channels for support bolts of lifting and pivoting devices of the
2. The State of the Art
In known tailgate structures the vehicle-mounted transverse support for the tailgate usually is a tetragonal pipe receiving having tetragonal sleeves provided with support flanges for the lifting and pivoting devices welded thereto (DE 31 29 789) or on which the sleeves are slided from both sides and anchored thereto by holding clamps or other fasteners, such as threaded bolts. The support flanges which are provided with precisely machined cylindrical receptacles for the support bolts of the lifting arms and pivoting devices have to be conformed to the tetragonal sleeves and they have to be welded to them. At those positions of the front surface of the tailgate which are to be engaged by the lifting arms and pivoting devices, inserts formed as special castings have to be provided. These inserts are also provided with machined support bolt receptacles, and they have to be welded to tailgate struts as well as with the tailgate proper.
Overall, this known construction has been found to be rather complex, because it requires a plurality of separate components which have subsequently to be assembled by welding and screwing. Not only do such components involve complex manufacture, but they also increase the weight of the vehicle and require extended assembly times. Moreover, with vehicles of different widths each type of vehicle necessitates a special component set.
OBJECTS OF THE INVENTION
The invention aims at providing a mounting device of the kind referred to in the introduction which may be manufactured in a simple and cost-efficient manner, which requires few component parts, which may be quickly mounted, and which is easily adaptable to different types of vehicles. while at the same time reducing weight.
BRIEF SUMMARY OF THE INVENTION
In accordance with the invention, the mounting device is characterized by the lateral support strut for mounting on a vehicle comprising an extruded box profile of substantially tetragonal cross-section made of aluminum and provided at its upper and lower surfaces with continuous grooves extending along the entire box profile for positively and frictionally receiving the ends of cantilevers of the support flanges for the lifting and pivoting devices. The support flanges are made from sections of an extruded hollow aluminum tubes. Such support flanges are also provided on the forward surface of the tailgate. They are provided with cylindrical through-channels for receiving support bolts of the lifting and pivoting devices and are welded to the loading platform.
In a preferred embodiment the ends of the cantilevers inserted into the elongate grooves in the box profile are additionally connected therewith by welding.
With the construction according to the invention, the entire mounting device of a tailgate may be made up of a few basic components, e.g., three extruded hollow aluminum profiles or braces. The structure of the device itself is very simple since the support flanges, once they have been cut, may be inserted or snap-fitted into the box profile without further processing, subsequent securing being carried out by short welding seams or welding spots. It is not necessary further to process the through-channels in the support flanges; if anything, they need simply to be wiped and are thereafter in condition for receiving the support bolts of the lifting and pivoting devices. At the same time, the construction in accordance with the invention may be easily adapted to different vehicles since the support flanges may be inserted into the elongate groove at any position, and they may then be
