A well-known body of a cargo vehicle, which has a bottom with a rear part bent upwards at a certain angle, front and side stationary (immovable) sides | see stalemate. of Ukraine

The main technical drawback of the known body is the absence of a rear board. When the bottom of the body at the end is made at an angle ("to rise"), it does not allow it to be loaded completely, at least to the level of the height of the side boards, because it (the load) will simply spill out of the body.

The body of a cargo vehicle is also known, which has a bottom and sides, one of which is made rotatable relative to the bottom of the body, due to its attachment to the bottom with a hinge. At the same time, the upper cantilevered (free) edges of the rotating side are connected to the corresponding upper edges of the adjacent non-rotating sides with the help of stretchers, which limit the rotation of this side to an angle of no more than 30" | see pat. of the Russian Federation Mo 2463771 from class AOTO 91/ 00 published on October 20, 2012.

The main structural disadvantage of the known technical solution is the impossibility of locating the turning board in the same plane as the bottom of the body due to the restrictions imposed by the stretchers. Since in the open state the turntable always remains at an angle to the bottom, in order to completely unload such a body, it must be tilted at a very large angle, almost vertically, since an incompletely opened turntable will prevent the load from shifting from the body.

The closest in essence and effect to be achieved, and which is accepted as a prototype, is the body of a cargo vehicle, which has a bottom, front and side stationary (fixed) sides and a rear rotating (moving) side, the upper corners of which are hinged with the upper corners of adjacent stationary sides, see stalemate.

VbOR 1/24 published on November 15, 2000 in Byul. Mo 61.

The advantage of such a kinematic scheme of hinged attachment of the turning board to the body is that

Therefore, it can open independently (voluntarily) when the body is tilted and will not interfere with the movement of the load along the body when it is unloaded, and also, under the action of gravity, it automatically returns to its original state when the body is lowered onto the frame.

However, the main structural disadvantage of the known technical solution is that such a swivel board does not allow you to tightly close the body from the back (even when the body is new), which, when transporting loose cargoes, for example, grain material, leads to their partial loss due to spillage in the cracks between the side and the body. In practice, these gaps are plugged every time by means of means, most often, fabric gaskets, or gaskets are attached along the contour of the board, which quickly wear out due to the dynamic load on the body (oscillation of the body) during the movement of the vehicle, which creates certain inconveniences, is unreliable, forces to spend some time.

The basis of the useful model is the task of further improving the design of the body of a cargo vehicle by forming a tight locking connection between the rear movable side and the bottom and side sides to prevent spontaneous spillage of bulk cargo from the body due to a fundamental change in the kinematic scheme of the connection of the movable rear side with vehicle body and its opening/closing mechanism.

The solution to the problem is achieved by the fact that the body of a cargo vehicle, which has a bottom, front and side fixed sides and a rear movable side, according to the proposal, the rear side is located in oppositely directed vertical grooves made on the rear ends of the side sides of the body, and the rear end the bottom of the body has a step for the tailboard to rest on when closed, the tailgate being driven (opening/closing) by a pair of vertical hydraulic cylinders mounted on the sidewalls next to the tailgate outside the body of the goods vehicle.

Thanks to the location of the rear movable side near the end of the body, it makes it full-sized and allows it to be filled completely to the level of all four sides.

Thanks to the location of the rear board in oppositely directed vertical grooves, it allows it to move along the grooves vertically, opening or closing the rear board completely or partially, that is, the rear board acquires a sliding design, and the vertical grooves together with the step on the bottom, in turn, allow you to get a lock with connection between the rear side and the body, preventing spillage of loose cargo during their transportation without additional sealing of the gaps (due to the absence of such), which take place in bodies with conventional rear hinged sides.

Thanks to the arrangement of hydraulic cylinders vertically near the rear board, the bending moment is reduced as much as possible, therefore it is possible to use hydraulic cylinders of smaller power and size, and therefore weight, to arrange them compactly, without going beyond the dimensions of the body.

Such proposed structural changes allow, in general, to expand the technical characteristics of the body, increase its load capacity, and also save bulk cargo (for example, grain, seeds of various agricultural crops) from loss during transportation by preventing the possibility of its spilling into gaps in the body due to the lack of such.

Therefore, the entire set of proposed essential features, obtained thanks to the introduction of appropriate structural changes in the body of a cargo vehicle, together allow to achieve a certain technical result formulated in the statement of the problem.

The further essence of the proposed technical solution is explained together with the illustrative material, which shows the following: fig. 1 - general view of the proposed body of a cargo vehicle (on the example of a tractor semi-trailer) with an open (raised) rear side of the sliding structure; fig. 2 - the same, with the rear board closed (lowered).

The explanation of the essence of the proposal is revealed on the example of a tractor semi-trailer, although the type of body of the cargo vehicle does not play any role - the essence of the proposal does not change from this.

The proposed cargo vehicle body contains the bottom 1, fixed front side 2 and side sides 3. The movable rear side 4 is located in oppositely directed vertical grooves 5 made on the rear ends of the side sides C of the body, along which the rear side 4 can move in the vertical direction. The rear end of the bottom 1 of the body has a step 6, on which the rear side 4 rests in the closed state. The step b and the vertical grooves 5 together form a locking connection that reliably and tightly closes the body cavity. The tailboard 4 is driven (opening/closing) by means of a pair of vertical hydraulic cylinders 7 installed on the side boards Next to the tailboard 4 outside the truck body

From the vehicle. In addition, resting the stern 4 on the step 6 allows you to completely unload the hydraulic cylinders 7.

The body is traditionally installed stationary or hinged (for dump trucks) on a frame 8 with wheels 9. In the latter case, a hydraulic device (not shown due to common knowledge) of any known design (does not matter) is located under the body.

The proposed body of a cargo vehicle with a tailboard of 4 sliding construction works in the following way.

Before loading the body with cargo, the rear side 4 is lowered with the help of hydraulic cylinders 7 down the vertical grooves 5 and rests on the step 6, forming a volume of the body tightly closed from all sides, which allows it to be completely filled with the cargo to be transported. Cargo, for example, grain, is transported to the place of unloading.

At the same time, the bulk cargo is not lost due to the fact that the vertical grooves 5 and step 6 form a locking connection. Further, with the help of hydraulic cylinders 7, the rear side 4 is brought to the top (similar to the extension of the slide valve), forming a gap (hole) between the rear side 4 and the bottom 1 of the body of the required size. As much grain as needed is poured into this hole, forming a pile. If at the same time the vehicle moves, the cargo will be poured out in an even layer. This is important if, for example, vegetables or seeds, grain, which need to be dried before long-term storage, are used as cargo. If necessary, the body is raised (tilted) using a hydraulic drive. After unloading the cargo, with the help of hydraulic cylinders 7, the rear side 4 is lowered down.

Since the rear board 4 moves along the grooves 5 only vertically, the body can be brought to the shelter to any opening through which the body is loaded/unloaded.

Rear board 4, lifted up, will not interfere with this.

Of course, the body of any cargo vehicle, even railway wagons and semi-wagons, can be equipped with such a rear side of the 4-slider design.

The essential difference between the proposed technical solution and the previously known one is the change in the principle of opening the rear side 4 - from a rotary to a movable vertical one, as well as the use of a locking connection between the elements of the body and the rear side 4, which allowed the proposed body of a cargo vehicle to acquire new technical and functional because the properties increase the useful volume of the body cavity, increase the safety of maintenance, prevent the loss of bulk cargo, and also expand the area of use of such a body. None of the known bodies of cargo vehicles can possess the specified properties, since they do not contain the entire set of essential features inherent in the proposed technical solution.

The proposed technical solution has been tested in practice. The body of a cargo vehicle does not contain parts or components that could be reproduced at the current stage of development of science and technology, in particular, in the field of vehicle production, from which it follows that the proposal is industrially suitable. In the known sources of patent documentation and scientific and technical information, similar bodies, trailers, semi-trailers for the transportation of goods with the specified distinctive features and advantages have not been found, and therefore, the proposed technical solution meets the criterion of novelty, and therefore it is considered to be eligible for legal protection.

The technical advantages of the proposed technical solution, in comparison with the prototype, include the following: - expansion of the technical and functional capabilities of the body by changing the principle of opening/closing the rear side; - storage of loose goods due to the use of a lock connection between the rear side and the body; - increasing the safety of service due to the automation of changing the spatial position of the rear board.

The social effect of using the proposed technical solution, in comparison with the prototype, is obtained due to increased safety and reduced maintenance time of the vehicle body.

The economic effect of the use of the proposed technical solution, in comparison with the prototype, is obtained due to storage from losses of loose goods, for example, storage of crops.

Having described the proposed truck body, it should be apparent to those skilled in the art that the foregoing is merely illustrative and not restrictive as presented by this example. Numerous possible modifications

Of the elements of the movable rear side of the body, in particular, the change of shape, structure, drive for its movement, can change depending on the specific conditions of operation, and, of course, are within the scope of one of the usual and natural approaches in this field of knowledge and are considered as such , which are within the scope of the proposed technical solution.

The quintessence of the proposed technical solution is that the body is equipped with a vertical rear side of the sliding structure, and this very fact made it possible to provide the proposed body of any cargo vehicle with the above and other advantages. Changing the principle of opening the rear side of the body and the formation of the locking mechanism to some other one will inevitably limit the range of advantages listed above and cannot be considered new technical solutions in this field of knowledge, since others, similar to the described body with a movable rear side, will no longer require any creative approach from designers and researchers, and cannot be considered the results of their creative activity, or new objects of intellectual property that comply with current legislation in the field of intellectual property and fall under the objects suitable for protection by protective documents.
