Description

Tipping vehicle with adjustable tilt axis and adjustment device for adjusting a tilt axis

Technical field

The invention relates to a tipping vehicle with a tilting axis that can be adjusted transversely to the axial direction and to an adjusting device for adjusting such a tilting axis according to the preamble of the independent claims. State of the art

In the following, a tilting container is to be understood as any tiltable container suitable for receiving transport goods, such as a trough, a tank, a truck or trailer bridge, a substantially level transport platform etc. A tipping vehicle is understood to be any land vehicle provided with a tipping container, such as e.g. a truck designed as a single vehicle, a semitrailer consisting of a tractor and a semi-trailer, a vehicle trailer, a railway wagon, etc.

A large number of embodiments of trucks and / or articulated lorries designed as tipping vehicles are known. They are particularly widespread for transport in the construction industry, since they enable simple and quick loading and unloading of the transported goods. The tilting container can usually be pivoted about a tilting axis by means of a tilting device, which is arranged transversely to the axial direction on the vehicle chassis of the tilting vehicle, the tilting device often comprising at least one hydraulic cylinder.

In order to be able to adjust the tipping height when tipping over and / or to prevent the tipping vehicle from falling over when tipping over, tipping vehicles are also known in which the tipping axis is arranged on the vehicle chassis, optionally adjustable transversely to the axial direction. In German patent DE-C-455 614 Ernst Wirz describes a dump truck that has a tilting container for bulk material that can be tilted about a tilting axis, the tilting axis designed as guide rollers being displaceable upwards along guides so that the bulk material can be brought directly into one Railway wagon can be emptied.

The British patent application GB-A-1 502 614 by Gordon Hoy relates to a trailer with a tilting container which can be tilted about a tilting axis. So that the trailer does not fall over when the tipping container is tipped, the tipping axis can be swiveled up and forward using a swivel arm so that it comes to rest in front of the trailer axle. According to the American patent US-A-5 069 507 by VT Lindsey, it is known to design a trailer with a trough which can be tilted about a tipping axis in such a way that the trough (and also the tipping axis) with respect to the trailer chassis can either be raised or lowered Position can be adjusted. In the lowered position, the trough can be conveniently loaded by hand. In addition, the trailer with the tipping axle in its lowered position has favorable driving behavior. To tilt the trough, the tilt axis is brought into an elevated position in which the rear lower end of the trough, which overhangs over the tilt axis, does not touch the ground.

The German patent application DE-A-2 251 198 describes a platform-shaped tilting container which can be tilted about a tilting axis by means of a lifting cylinder. The tilt axis is accommodated in two parallel pivot arms which are pivotably connected to a vehicle chassis about pivot bearings parallel to the tilt axis. The swivel arms can be actuated by means of a swivel piston and swiveled around the swivel bearings in order to adjust the dumping height when the tilting container is tilted.

It turns out to be disadvantageous that conventional tipping vehicles are restricted to use for a few specific applications due to the specific shapes of the tipping containers and / or their openings for emptying the same, special arrangements of the tipping containers on the vehicle chassis and tipping container materials that are only suitable for certain transport goods , for which the tipping vehicles were specially designed. For example, it is not possible at all or only with great difficulty that the same tipping vehicle can be used to transport on the one hand bulk material-like covering material for the construction of road surfaces and on the other hand piece goods (eg in the form of construction vehicles). Therefore, a construction company must have and maintain a fleet of a variety of different tipping vehicles for different applications, which is inefficient and expensive. Presentation of the invention

The object of the present invention is to provide a tipping vehicle of the type mentioned at the beginning which is provided with an adjustable tipping axis and which can be used in a variety of ways for different applications, and a tipping axis adjusting device for such a tipping vehicle.

The solution to the problem is defined by the features of the independent claims. According to the invention, a tipping vehicle is provided with a vehicle chassis, a tilting container designed for the transport of bulk goods and pivotable by means of a tipping device with respect to the vehicle chassis about a (geometric) tipping axis, and an adjustment device which makes it possible to selectively tilt the tipping axis with respect to the vehicle chassis transversely to the axis direction to adjust. According to the invention, the tilting container is further designed for the transport of a truck and the adjusting device and the tilting device are designed and arranged in such a way that the tilting container by means of the tilting device and the adjusting device is optionally in a loading position suitable for driving the truck onto the tilting container and in a position suitable for transport the bulk goods and / or the truck can be brought into a suitable transport position.

The tipping vehicle according to the invention can thus optionally be used for the transport of bulk goods and / or the transport of a truck. On the one hand, the transported bulk goods can be unloaded from the tipping vehicle after the transportation in a manner customary for tipping vehicles, by tipping the tipping guide around the tipping axis by means of the tipping device. On the other hand, the tilting container can be adjusted to a loading position such that no additional loading device (such as a stationary loading ramp) is required for loading a truck to be transported onto the tipping vehicle or unloading the truck from the tipping vehicle. Rather, by means of the adjustment device for the tipping axis and the tipping device, the tipping container of the tipping vehicle can be brought into a loading position in such a way that the truck to be loaded can under its own power (that is, by means of its usual travel drive) from a flat roadway onto the tipping container or onto the floor drive up and from there back down to the level road. The adjustment device is preferably designed and arranged in such a way that in the loading position the tilting axis is positioned further back and lower with respect to the vehicle chassis than in the transport position. As a result, after the tilting axis has been adjusted into its position corresponding to the loading position, the tilting container needs to be tilted or tilted backwards only comparatively little from a horizontal position until it reaches its loading position, in which the position to be loaded Trucks in the area of the rear end of the tipping container can hit this or the bottom thereof. The adjustment device is preferably dimensioned and arranged in such a way that, in order to drive a truck onto the tipping container from a horizontal, level carriageway from the tipping container in the loading position, only by an angle of less than 20 degrees, preferably even by an angle of less than 15 degrees, in particular by an angle of only about 12 degrees with respect to the horizontal.

The tilting container can further be provided with means for optionally extending to the rear of the tilting container base designed for driving on by a truck or by another vehicle. These extension means make it possible to extend the bottom of the tipping container to the rear if necessary in order to create a longer transport platform for vehicle transport. These extension means further facilitate the loading and unloading of vehicles in that the inclination of the tilting container required to reach the loading position is reduced by extending the bottom of the tilting container to the rear. As a transport platform extension, e.g. the tailgate of a tipping body designed for the transport of bulk goods and / or a truck can be used, either as the sole transport platform extension or in conjunction with other transport platform extension means.

According to a preferred embodiment of the invention, the adjusting device comprises at least one elongated connecting part which is pivotably pivoted on the vehicle chassis in the region of one longitudinal end about a (geometric) pivot axis and pivotably on the tilting container in the region of the other longitudinal end about the tilting container in such a way that an adjustment the tilt axis on a circular path around the pivot axis is made possible. Such an adjustment device, which is based on a swivel mechanism, the one or more about a common pivot axis includes swiveling connecting parts, can be constructed mechanically extremely simple and lightweight. The pivot axis is preferably arranged parallel to the tilt axis. The tilting axis can be adjusted in a circular path around the pivoting axis with respect to the vehicle chassis by means of the adjusting device designed in the manner of a pivoting mechanism, ie it can be displaced in the vehicle longitudinal direction and in the vehicle vertical direction with respect to the vehicle chassis. Instead of one or more connecting parts pivotable about a pivot axis, however, the adjusting device can in principle also have other means for adjusting or displacing the tilting axis with respect to the vehicle chassis. For example, the (geometric) tilting axis can be designed in the form of two guide rollers attached to the tilting container, which can be moved along two parallel guide rails fixedly attached to the vehicle chassis transversely to the axis direction defined by the tilting axis.

In a tipping vehicle with an adjustment device based on a swivel mechanism of the type described above, the swivel axis is preferably at

Vehicle chassis near the rear longitudinal end of the vehicle chassis and the

Tilt axis on the tilting container arranged substantially in front of the rear longitudinal end of the tilting container, in particular by more than 1 meter in front of the rear end of the tilting container.

By arranging the pivot axis at the rear longitudinal end of the vehicle chassis, it is ensured on the one hand that the inclined position of the tilting container in the loading position is not excessively impeded by the rear end of the vehicle chassis. On the other hand, the arrangement of the tilt axis significantly before the rear longitudinal end of the

Tilting container achieves that suitable for opening a truck

Loading position, in which the rear end of the bottom of the tilting container essentially extends down to the bottom, can already be produced with a comparatively slight inclined position of the tilting container.

In the case of a tipping vehicle with an adjustment device which has at least one connecting part which can be pivoted about a pivot axis, the connecting part is advantageously of an angular configuration. The angular design of the connecting part enables a space-saving arrangement of the same in the region of the rear end of the vehicle chassis without impeding the tilting process or the adjusting process. A tipping vehicle according to the embodiment of the invention described above, in which the adjusting device has at least one connecting part which can be pivoted about a pivot axis, can further comprise pivoting drive means which make it possible to pivot the connecting part with respect to the vehicle chassis about the pivot axis into a plurality of desired pivot positions and hold in these swivel positions during a tilting process. By using the adjusting device to bring the tilting axis into different positions or to shift it and to hold it in these positions - especially during the tilting of the container - an outlet opening of the tilting container, which is used to empty bulk goods, can of course also be positioned accordingly. It is thus possible to adjust the pouring height and / or the overhang of the pouring opening according to the respective requirements. However, the possibility of adjusting the tipping axis in different positions and of holding the tipping axis in these positions can also be useful for driving a vehicle onto the tipping container or for lowering a vehicle from the tipping container.

The swivel drive means preferably comprise at least one linear drive with a hydraulically actuable piston-cylinder arrangement, the piston-cylinder arrangement being able to be provided with a double-acting differential cylinder which can be used for both thrust and train by alternating piston action. Hydraulic drives of this type are particularly widespread for construction machines and have also proven themselves in harsh environments. Instead of a hydraulic drive, however, the swivel drive means can also comprise other drive means for motorized actuation of the tilting axis adjusting device. In order to pivot the connecting part around the pivot axis, the pivot drive means can e.g. a spindle-nut drive acting between the vehicle chassis and the connecting part, a drive with gearwheel and toothed rack, a motor which acts on a pinion which is fixedly connected to the pivot axis via a gearwheel transmission or a chain, a direct-driven rotary axis or any other suitable drive for include a rotary axis.

In the case of an adjusting device, a connecting part which can be pivoted about a pivot axis, and pivoting drive means which have a linear drive, the pivoting drive means are advantageously connected to the by means of a lever mechanism Coupled part, wherein this lever mechanism comprises at least a first elongated steering lever which is articulated at one longitudinal end on the linear drive and at the other longitudinal end on the vehicle chassis, and at least a second elongated steering lever which is articulated at one longitudinal end on the linear drive and at the other longitudinal end of the connecting part. Such a lever mechanism can on the one hand ensure that the connecting part can be actuated over a large angular range around the pivot axis without excessively large forces acting between the linear drive and the connecting part, which can arise due to the operation of the pivoting drive means in the vicinity of a dead area , This also makes it possible at the same time that the connecting part can be held in different swivel positions by means of the linear drive with comparatively little effort. On the other hand, such a lever mechanism also enables a comparatively space-saving construction and arrangement of the entire tilting axis adjusting device.

In a tipping vehicle according to the embodiment of the invention described above, in which the adjusting device has at least one connecting part pivotable about a pivot axis, the possibilities for adjusting the tilting axis can be expanded if the connecting part is designed for optional lengthening and shortening in its longitudinal direction, whereby it can preferably be fixed in the desired length. For this purpose, the connecting part can be made telescopic, and drive means can be provided for a hydraulic length adjustment of the connecting part. Further possibilities for adjusting the tilting axis can be created by attaching the tilting axis to the tilting container so that it can be moved and locked in various sliding positions. For this purpose, for example, a tilt axis in the form of a mechanical axis of rotation can be mounted in an axle bearing fixedly attached to a slide, the slide itself being optionally displaceable along a linear guide fixedly attached to the tilting container and can be locked in various sliding positions. Additional adjustment options for the tilt axis result if the swivel axis is attached to the vehicle chassis and can be moved and locked in various sliding positions. For this purpose, the pivot axis can be mounted, for example, in an axle bearing fixedly attached to a slide, the slide itself along a linear guide permanently attached to the vehicle chassis can be moved and locked in various sliding positions.

Furthermore, the adjusting device, which has at least one connecting part which can be pivoted about a pivot axis, can be provided with locking means which allow the connecting part to be locked in a desired pivoting position with respect to the vehicle chassis. These locking means can e.g. have bolts attached to the vehicle chassis, which can be inserted into bores on the pivot axis and / or on the connecting part.

According to the invention, an adjustment device is provided, which is provided for a tipping vehicle, which is provided with a vehicle chassis and a tilting container designed for the transport of bulk material and pivotable by means of a tilting device with respect to the vehicle chassis, the tilting axis being adjusted with respect to the Vehicle chassis is optionally adjustable transversely to the axis direction, in that the adjustment device is designed and arranged in such a way that the tilting container by means of the tilting device and the adjusting device can optionally be placed in a loading position suitable for driving a truck onto the tilting container and in a position suitable for transporting the bulk material and / or the truck can be brought into a suitable transport position.

Ways of Carrying Out the Invention

1-3 shows a tipping vehicle 10 according to a first preferred embodiment of the invention in a simplified side view. In Fig. 1, the tipping container 20 of the tipping vehicle 10 is in a first, for pouring bulk material out of the Tilt container 20 shown suitable position with respect to the vehicle chassis 12 of the tipping vehicle 10. This position is referred to below as the tilt position. In the illustration in FIG. 2, the tipping vehicle 10 is shown with the tipping container 20 in a second position, hereinafter referred to as the loading position, which is suitable for loading a truck 60 (indicated by way of illustration). 3 shows the tipping vehicle 10 with the tipping container 20 in a third position, hereinafter referred to as the transport position, with respect to the vehicle chassis together with the truck 60 loaded onto the tipping container 20, the side walls of the tipping container 20 being transparent in a manner which is not in itself applicable are shown in order to illustrate the arrangement of the transported truck 60 on the tipping container 20.

The tipping vehicle 10 shown in FIGS. 1 to 3 is a truck 10 designed as a semitrailer. It comprises a tractor (also called a tractor, semitrailer or tractor) and a trailer in the form of a semitrailer.

A tipping container 20 in the form of a tipping trough 20 designed for the transport of bulk material is arranged on the trailer chassis 12. For the purpose of tipping, the tipping trough 20 is pivotably articulated about a tilting axis 15 arranged essentially horizontally and transversely to the longitudinal direction of the trailer on a connecting part 30 connected to the trailer chassis 12 via the swivel joint 25. Furthermore, a tilting device with a hydraulically operated telescopic cylinder 50 is arranged on the trailer for the purpose of tipping. One longitudinal end of this telescopic cylinder 50 is pivotally connected to the trailer chassis 12 in a front region of the trailer about a first connecting axis 52 parallel to the tilting axis 15, while the other longitudinal end of the telescopic cylinder 50 is hinged to the front wall of the tipping trough 20 about a second connecting axis 54 parallel to the tilting axis 15 is pivoted about. By actuating the telescopic cylinder 50, the tipping trough 20 can be pivoted about the tipping axis 15 in order to e.g. to empty the bulk material (not shown) from the tipping trough 20 in the tilted position shown in FIG. 1.

In the embodiment of the invention shown in FIGS. 1 to 3, the tipping trough 20 can be pivoted about the tipping axis 15 at a location in a rear region of the trough bottom which is approximately 120 cm in front of the rear end of the trough bottom hinged to a longitudinal end of a plate-shaped, elongated connecting part 30. This connecting part 30 is pivoted at its other longitudinal end about a pivot axis 25 close to the rear end of the trailer chassis 12 on this. The pivot axis 25 is arranged parallel to the tilt axis 15, ie essentially horizontally and transversely to the longitudinal direction of the trailer on the trailer chassis 12.

In the embodiment of the invention shown in FIGS. 1 to 3, the connecting part 30 is essentially designed as an integral, elongated plate 30 with a fixed length of approximately 120 cm. In other variants of the invention, instead of a single connecting part, several, e.g. tubular connecting parts can be provided which are articulated on the tipping container so as to be pivotable about a common geometric tilt axis and pivotable on the trailer chassis about a common geometric pivot axis. The geometric tilt or Pivot axes in the usual manner can be realized by one or more coaxially arranged swivel joints which comprise axle journals, continuous axes of rotation, drive shafts, roller bearings, slide bearings and / or other joint means which are usual for swivel joints.

The connecting part 30 connecting the tipping trough 20 to the trailer chassis 12 is part of an adjusting device which serves for the optional adjustment or displacement of the (geometric) tipping axis 15 with respect to the trailer chassis 12 transversely to the axial direction of the tipping axis 15. The swivel device further comprises swivel drive means (not shown in FIGS. 1-3) which allow the connecting part 30 to be swiveled with respect to the vehicle chassis 12 about the swivel axis 25 into a desired swivel position and to be held in this swivel position. In the exemplary embodiment shown in FIGS. 1-3, the geometric pivot axis 25 is defined by two axle journals, which are formed on the connecting part 30 in a rotationally fixed and non-displaceable manner. These two axle journals are mounted in two axle bearings attached to the vehicle chassis. The swivel drive means comprise two raster disks, which are each attached to one of the two axle journals in a rotationally fixed manner and can each be moved step by step from one latching position to the next by means of a hydraulically actuated push rod, around the connecting part 30 in each case by a certain angular step about the swivel axis 25 with respect to the Vehicle chassis 12 to pivot. It However, other suitable means for the pivot drive of the connecting part 30 are also possible.

1, the tipping trough 20 is in the tilting position suitable for emptying bulk material. The longitudinal end of the connecting part 30 which defines the tilt axis 15 is pivoted upwards and somewhat backwards with respect to the trailer chassis 12 about the pivot axis 25. By means of the swivel drive means, the swivel position of the connecting part 30 with respect to the swivel axis 25 and thus the position of the tilt axis 15 with respect to the trailer chassis 12 can be adjusted. This allows the dumping height and the overhang of the outlet opening to be regulated when pouring out the bulk material. The actual tipping process for emptying the bulk material is carried out by actuating the telescopic cylinder 50, the tipping trough 20 being pivoted about the tipping axis 15.

The bottom of the tipping trough 20 of the tipping vehicle 10 shown in FIGS. 1-3 is designed to be driven on by a truck 60. In order to load the truck 60 to be transported into the tipping trough 20, the connecting part 30 of the tilting axis adjusting device is pivoted rearward about the pivot axis 25 into the loading position shown in FIG. 2. In the loading position, the tilt axis 15 is essentially in its rearmost possible position and is also arranged much lower than in the transport position shown in FIG. 3 and of course also in the tilt position shown in FIG. 1. After the connecting part 30 has been brought into its pivoting position shown in FIG. 2 by means of the tilting axis adjustment device, two support beams 44, which are arranged in the rear region below the trough bottom, are pulled out towards the trough bottom beyond the rear end of the trough bottom and the tailgate 40 of the trough 20 is folded outwards around a hinge 42, by means of which the tailgate 40 is articulated at its lower end on the trough floor, so that it rests on the two support beams 44. The tailgate 40 now serves in conjunction with the two support beams 44 as a platform extension extending rearward for receiving the truck 60 to be loaded into the tipper body 20 and as an access ramp via which the truck 60 can drive into the tipper body 20. After the ramp has been installed, the tipping trough 20 is raised by means of the telescopic cylinder 50 of the tipping device and pivoted about the tipping axis 15 until the ramp or the platform extension touches the ground. In this loading position of the tipping trough 20 shown in FIG Trucks 60 to be loaded drive into the tipping trough 20 from a flat, horizontal roadway on which the tipping vehicle 10 and the truck 60 stand, whereby due to the tilting axis 15 shifted to the rear, only a slight increase in the ramp and the trough floor serving as a transport platform must be overcome The slope in the embodiment of the invention shown in FIGS. 1-3 is approximately 12 degrees.

The tipping trough 20 is then moved forward again by means of the swivel drive means and the tipping device 50 and lowered onto the trailer chassis 12, the connecting point 30 of the tipping axis adjusting device being swung forward so that the tipping axis 15 is in its foremost position until the Tipping body 20 has reached the transport position shown in FIG. 3

4-8 show a tipping vehicle 110 and an adjusting device for adjusting the tipping axis 115 of this tipping vehicle 110 according to a further preferred embodiment of the invention. The tipping vehicle 110 shown in FIGS. 4-8 is, with the exception of its adjusting device for adjusting the Tilt axis 1 15 is essentially identical to the tilt vehicle 10 shown in FIGS. 1-3. For the sake of clarity, only the elements essential for understanding the function of the adjusting device are shown in detail in FIGS. 6-8, while the outlines of the tipping vehicle 110 and the tipping container 120 are only indicated with broken lines. Furthermore, for the sake of clarity, the tipping container is shown in FIG. 5 120 and in FIGS. 4 and 5 the stops 190, 192 described below are not shown

The tipping vehicle 110 shown in FIGS. 4-8 is in turn designed as a semitrailer with a semitrailer and a trailer in the form of a semi-trailer. A tipping trough 120 designed for the transport of bulk material is arranged on the trailer chassis 112, for the purpose of emptying bulk material by means of a tilting device comprising a telescopic cylinder (not shown) can be tilted around the tilt axis 115. The bottom of the trough 120 of the one shown in FIGS. 4-8 The tipping vehicle is in turn also designed to be driven on by a truck (not shown).

The tipping trough 120 and the trailer chassis 1 12 of the tipping vehicle 110 shown in FIGS. 4-8 are connected to one another via a tilting axis adjustment device which is arranged in the rear region of the tipping vehicle 110 essentially between the trailer chassis 1 12 and the tipping trough 120.

The tilting axis adjustment device comprises two essentially identical, elongated, one-piece connecting parts 130, 230. The two connecting parts 130, 230 are angular and each have a long leg 132 and a short leg 134, which are arranged at an angle to one another and in Area of the connection angle are firmly connected. The two angular connecting parts 130, 230 are each arranged parallel to one another, eccentrically with respect to a vertical center plane extending in the longitudinal direction of the vehicle and symmetrically to one another with respect to this center plane. They are articulated both with the tipping body 120 and with the vehicle chassis 1 12. The two ends of the short legs 134, which are distant from the connecting angles, are each pivotably articulated on the trailer chassis 112 about an axis 127, which extends essentially over the entire chassis width and is arranged horizontally and transversely to the longitudinal direction of the vehicle, while the two ends of the long ones remote from the connecting angle Legs 132 are pivoted to the tipping trough 120 about axis bolts 11 17, 18 arranged coaxially to one another and parallel to the axis 127 on the underside of the tipping trough 120. The two axle bolts 1 17, 1 18 define the (geometric) tilt axis 1 15 of the tilting vehicle 1 10, while the axis 127 defines the geometric pivot axis 125, hereinafter referred to as the pivot axis 125 of the tilt axis adjusting device. The tilt axis 1 15 defined by the two axis boices 1 17, 1 18 is arranged approximately 120 cm in front of the rear end of the tipping trough 120, and the distance between the tilt axis 1 15 and the pivot axis 125 parallel to this likewise measures approximately 120 cm.

The two connecting parts 130, 230 are each arranged in such a way that their angular shapes lie in the vertical planes extending in the longitudinal direction of the vehicle, wherein they are further arranged in such a way that the connecting angles are described in the following Transport position are above the straight connecting lines between the leg ends distant from the corresponding connecting angles, while the connecting angles in the loading position described below lie below these connecting lines. Overall, the arrangement of the tilting vehicle 110 shown in FIGS. 4-8, formed from the two angular connecting parts 130, 230, essentially corresponds in its function to the elongated connecting part 30 of the tilting vehicle 10 shown in FIGS. 1-3, the tilting axis 15 and the The pivot axis 25 of the tilting vehicle 10 shown in FIGS. 1-3 corresponds to the tilt axis defined by the two axle stubs or the pivot axis 125 defined by the transverse axis 125. In contrast to the connecting part 30 shown in FIGS. 1-3, however, the connecting arrangement formed from the two angular connecting parts 130, 230 can be arranged between the trailer chassis 1 12 and the tipping trough 120 in a much more space-saving manner without the tipping of the tipping trough 120 or the adjustment the tipping trough between the transport, tipping and loading positions is excessively obstructed.

For the actuation of the two connecting parts 130, 230 around the pivot axis 125 (ie for the purpose of adjusting the tilt axis 1 15 with respect to the trailer chassis 1 12), the tilt axis adjusting device comprises two essentially identical pivot drive mechanisms, each with one of the two connecting parts 130, 230 are coupled. One of these two rotary actuators is shown in detail in FIGS. 5-8 and is described in detail below.

The swivel drive mechanism for the connecting part 130 comprises a linear drive that can be used for both thrust and pull in the form of a hydraulically actuated piston-cylinder arrangement. The cylinder 170 is a double-acting differential cylinder 170. By alternately pressurizing a piston arranged in its interior, it can optionally move the piston in two opposite directions along the cylinder axis, so that a piston rod 172 connected to the piston passes through a passage in the cylinder wall on one Is passed through the longitudinal end of the cylinder, either away from cylinder 170 (ie on thrust) or towards cylinder 170 (ie on train). The stroke available to adjust piston rod 172 with respect to cylinder 170 is approximately 70 cm. The differtial cylinder 170 is articulated in the region of its longitudinal end distant from the passage for the piston rod 172 about a first transverse axis 174 parallel to the pivot axis 125 on a crossbar 114 of the trailer chassis 112, this transverse axis 174 approximately 150 cm in front of the trailer chassis 1 12 arranged pivot axis 125 and about 27 cm higher than this pivot axis 125 is arranged on the trailer chassis 1 12.

The piston rod 172 is pivoted at its longitudinal end remote from the cylinder 170 about a second transverse axis 176 parallel to the pivot axis 125 to a pair of two arcuate elongated steering levers 180, 181 arranged parallel to one another, each at one longitudinal end thereof. At their other longitudinal ends, these two arcuate steering levers 180, 181 are pivotably articulated on the trailer chassis 1 12 about a third transverse axis 182 parallel to the pivot axis 125, this third transverse axis 182 being approximately 22 cm in front of the pivot axis 125 and approximately at the same height as this pivot axis 125 Trailer chassis 1 12 is arranged. The essentially by the length of the arcuate steering lever 180,

181 determined distance between the second transverse axis 176 and the third transverse axis

182 measures approximately 33 cm.

Furthermore, a pair of two straight steering levers 184, 185, which are arranged in parallel and are arranged parallel to one another, are articulated about the second transverse axis 176 at one longitudinal end. At their other longitudinal ends, these two straight steering levers 184, 185 are articulated on the connecting part 130 about a fourth transverse axis 186 parallel to the pivot axis 125, this fourth transverse axis 186 on the long leg 132 of the connecting part 130, at a point close to that between the long 132 and the short leg 134 formed connection angle is arranged. The distance between the fourth transverse axis 186 and the pivot axis 125 measures approximately 39 cm, and which is essentially determined by the length of the straight steering levers 184,

185 determined distance between the second transverse axis 176 and the fourth transverse axis

186 also measures approximately 39 cm.

In the transport position of the tipping trough 120 shown in FIGS. 4-6, the tipping axis 115 lies approximately 105 cm in front of the pivot axis 125 and approximately 52 cm higher than this.

The connecting part 130 extends from the pivot axis 125 to the front and up to the tilt axis 1 15, and the piston rod 172 is pushed almost completely into the cylinder 170. In the transport position, the first transverse axis 174, the second transverse axis 176 and the third transverse axis 182 lie almost on a straight line which defines a dead center of the swivel drive mechanism for the connecting part 130.

In the transport position, the tipping trough 120 is further supported on the upper side of the connecting part 130 by a support stop 190, which is fixed approximately 33 cm before its rear end.

In order to adjust the tipping trough 120 from its transport position shown in FIGS. 4-6 into the tipping division shown in FIG. 7, the tipping trough 120 is initially only raised by means of the telescopic cylinder of the tilting device. Here, because the support stop 190 rests on the connecting part 130, the connecting part 130 is pivoted upward about the pivot axis 130. By means of this pivoting movement of the connecting part 130, the pivot drive mechanism comprising the cylinder 170, the piston rod 172 and the steering levers 180, 181, 184 185 is passively moved, so that it moves away from the region of its dead center caused by the arrangement of the first, second and third transverse axes 174, 176 and 182 is defined, is moved away.

As soon as the swivel drive mechanism is moved sufficiently far away from its dead center, it is actuated further by the piston-cylinder arrangement in the direction of the tilting position shown in FIG. 7, in that the piston rod 172 is hydraulically pushed out of the cylinder 170. As a result, the connecting part 130 is pivoted backwards and upwards via the pivoting drive mechanism. At the same time, the connecting part 130 is also pivoted about the tilt axis 115 with respect to the tipping trough 120 and the support stop 190 is moved away from the connecting part 130 until the connecting part 130 has reached its pivoting position shown in FIG. 7. The tipping trough 120 can then be pivoted about the tipping axis 115 by means of the tipping device until it reaches the tilting position shown in FIG. 7, the tipping of the tipping trough 120 by means of the tipping device about the tilting axis 115 simultaneously with the pivoting of the connecting part 130 can be carried out around the pivot axis 125 or after this pivoting. From the tilt position shown in FIG. 7, the connecting part 130 can be pivoted further back and down around the pivot axis 125 by means of the pivot drive mechanism until it reaches its pivot position shown in FIG. 8. Simultaneously with the swiveling process or also afterwards, the tipping trough 120 can be swiveled around the tipping axis 115 by means of the tipping device in order to reach the loading position shown in FIG. 8, in which the bottom of the tipping trough 120 falls backwards by approximately 12 degrees with respect to the Horizontal is slanted.

In the loading position, the connecting part 130 rests with its underside on a support stop 192 fixedly attached to the trailer chassis 1 12, which supports the connecting part 130 in the loading position of the tipping trough 120 shown in FIG. 8 and limits the pivoting movement of the connecting part 130 about the pivot axis 125 , The tilt axis 115 lies approximately 120 cm behind the pivot axis 125 and approximately 9 cm below it. In the loading position, the second transverse axis 176 is approximately 10 cm behind and 10 cm above the pivot axis 125, and the fourth transverse axis lies approximately 33 cm behind and 21 cm below the pivot axis 125. The pivot axis thus becomes arcuate in the loading position Steering levers 180, 181 and the straight steering levers 184, 185 essentially comprises the arrangement formed at the front, top and rear, the arc-shaped steering levers 184, 185 resting with the inside of the arc on the transverse axis 127 defining the pivot axis 125. Overall, the connecting part 130 is pivoted by an angle of approximately 160 degrees around the pivot axis 125 during the adjustment from the transport position shown in FIGS. 4-6 to the loading position shown in FIG. 8.

In summary, it can be stated that the invention provides a tipping vehicle provided with an adjustable tipping axis, which is versatile and can be used for different purposes, and a tilting axis adjusting device for such a tipping vehicle.
