Description

The invention relates to transport engineering, directly to devices that provide increased cross-country ability and increase the vehicle's cruising range. It is used in conditions of soils with low bearing capacity, and can be used on difficult road sections and terrain for self-recovery of stuck tracked vehicles and to increase the range when driving.

Known device for self-recovery of a tank (see [1], pp. 576, 577), which is a log adjacent to the external surfaces of the elements (tracks) of the vehicle's propeller interacting with the ground and attached to them by means of kinematic links (using cables). The log is installed perpendicular to the longitudinal axis of the mover, for which the ends of the log are placed on sections (links) of caterpillars located opposite each other on both sides of the longitudinal axis of the mover. When the tracks are moving, the log catches on the ground and the tank moves relative to the ground.

The disadvantages of the known device for self-recovery of a tracked vehicle are the significant mass of the log, insufficient strength due to the inconstancy of its physical and mechanical properties. For example, the density (mass) and strength of wood depends on moisture due to the hygroscopicity of the wood. The presence of defects in the wood also contributes to the decrease in strength. In addition, wood is highly flammable and can rot from dampness. The variability and the wide range of the tensile strength of the tree, depending on various factors, reduce the reliability of the self-recovery device as a whole.

The disadvantage of the log is also significant labor costs in preparing the vehicle for self-pulling, which are due to the fact that for even laying the log under the tracks of the vehicle (in order to avoid log breakage), it is necessary to level the soil for the entire length of the log in the place of its laying, and also for carrying logs require at least two people.

Due to its long length, the log takes up a lot of space on the vehicle. This creates additional inconvenience during transportation and the inability to use this place for installing additional equipment, for example, a fuel tank.

When using a log, it is not possible (to make a turn when changing the direction of exit) of a tracked vehicle in the shortest direction to the ground with the required bearing capacity.

The round shape of the log does not allow it to catch on dense ground.

The object of the present invention is to provide a structure for a combined vehicle self-recovery device free from the above disadvantages and to increase the vehicle's range.

The technical result is a decrease in the size and weight of the device, a decrease in the labor intensity of installation and dismantling, combined with an increase in the power reserve.

The technical result of the present invention is to reduce the size and weight of the device for self-recovery of the vehicle, increase reliability, ensure ease of use, reduce the labor intensity of installation and dismantling, expand technical capabilities, increase the range of the armored vehicle.

The essence of the invention is illustrated by drawings, where:

Figure 4 shows options for self-pulling a vehicle using a self-pulling cable attached to the tracks of the vehicle, where the integral tubular parts, together or separately, are used as a fixed support,

Fig. 5, Fig. 6, Fig. 7 show options for placing the combined device on the main battle tanks T90, T-90M, T-14 "Armata", respectively.

The combined device for self-recovery of the vehicle is made in the form of a composite tubular structure, consisting of several parts of the main (central) 1, left 2 and right 3, (Fig. 1) which are connected to an additional fuel tank 4 (Fig. 1) made in the form of a log for self-recovery of the tank and with its geometric dimensions and placed at the place of its installation. On the end ends of the additional fuel tank 4, removable supports 5 (Fig. 1) are put on, which are hollow inside, open at one end and closed with plugs 6 (Fig. 1) from the opposite.

Connecting elements 7 (Fig. 1) are made on the plugs in the form of a plate fixed at one end on the plug of a removable support; on the other there is a fastening for attaching the tubular part of the device to the left or right, depending on the location of the removable support 5, the same fastening is located in the middle part of the additional fuel tank for fixing the central tubular part of the structure (not shown in the figure) To maintain the rigidity of the removable supports, additional removable plug-in supports are provided in the form of disks 8 (Fig. 1), which are inserted into the removable supports before using the self-pulling device. In the center of the discs there are holes that allow you to insert the left or right parts of the tubular structure into them (Fig. 1).

On the elements of the tubular structure, support surfaces 9 (Fig. 1) are installed, flat in shape, made of durable material, on the main (central), right and left, respectively (Fig. 1), the support surface of which is not less or more than the support surface of the log for self-pulling vehicle.

An additional fuel tank 4, made in the form of a log for self-retrieval of the tank with its geometric dimensions, contains a longitudinal body 10 (Fig. 1) with two end bottoms 11, 12 (Fig. 1) attached to it by welding, and partitions installed inside the body , made on the body with a filler neck and a plug for draining fuel (Fig. 1), the partitions repeat the shape of the cross-section of the body and divide the internal cavity of the fuel tank into a number of chambers communicating with each other through holes formed by cutouts in the partitions and walls of the body, and are installed inside hulls in such a way that they expand the tank on all sides, (Fig. 1), along with the partitions performing a soothing function, which consists in extinguishing hydraulic shocks of fuel against the walls of the fuel tank, resulting from sudden vibrations and jolts of liquid fuel when moving, an armored vehicle, which also perform reinforcing function, not allowing the body to bend when creating excess in the tank and negative pressure or external force, which has a positive effect on the strength characteristics of the tank as a whole. In addition, the tank has an autonomous transfer pump with a check valve at the outlet of the pump (not shown in the figure), while the pump is connected by a pipeline to one of the external fuel tanks using a connecting sleeve (Fig. 1 option A) or with a fitting connected to the system supplying fuel to the tank from additional fuel barrels (Fig. option B). In addition, a system is installed on the tank for supplying exhaust exhaust gases from the engine to the fuel tank as fuel is depleted from it, in order to prevent the explosion of fuel vapors. The system consists of a fitting connected to the exhaust system of the armored vehicle using a pipeline with a flame arrester inside, a valve for relieving excess pressure in the tank (Fig. 1) and an emergency tank discharge device (not shown in Fig.).

In addition, the supporting surfaces attached to the integral tubular parts during their installation for transportation act as protection for the additional fuel tank on the vehicle.

In addition, when removable hollow supports and plug-in transport supports are installed, they act as additional protection for the additional tank on the vehicle.

In addition, the structure is collapsible, which provides for the possibility (to make a turn when changing the direction of exit) of the tracked vehicle in the shortest direction to the ground with the required bearing surface.

In addition, on the plugs of removable supports, the implementation of the connecting elements in the form of a plate fixed at one end of the plug of the removable support, which allows it to be used as rigid elements interacting with the ground.

In addition, the pointed ends of the right and left parts of the composite tubular structure can be used as a fixed support for self-recovery of the vehicle.

In addition, the installation of the fuel tank in place of the log for self-recovery allows it to be placed in the least affected part of the vehicle.

In addition, the design of the device allows the use of a standard set of rigging equipment.

The stated technical features are essential, since they affect the achieved technical result.

When studying other technical solutions in this field of technology, the features that distinguish the claimed device have not been identified.

The device for self-recovery of the vehicle works as follows.

In the process of self-recovery of the vehicle, removable supports 3 transmit the traction force from the elements 2 of the caterpillar propeller to the connecting elements in the form of a plate 4, which penetrate into the ground and create support for the propeller of the vehicle 1, provide effective adhesion to the ground simultaneously attached to the integral tubular parts, the supporting surfaces increase the area of the bearing surface and the vehicle 1 moves relative to the ground.

The reliability of the device is ensured by the use of a more durable (compared to wood - when using a log) material for the manufacture of the device, for example, metal.

Reducing the size and weight of the self-pulling device for a tracked vehicle is achieved by reducing the diameter of the combined device as compared to the diameter of the log for self-pulling the vehicle and the use of removable supports and integral tubular parts in the design, as opposed to hollow logs inside.

Weight reduction is also facilitated by the possibility of making the body of the additional fuel tank made of light metal or composite material. Additional fuel tank 4 (figure 1) operates as follows. When you turn on the toggle switch located on the fuel system control panel of the vehicle, an autonomous transfer pump with a check valve (not shown in the figure) is switched on at the pump outlet, while the pump is connected by a pipeline to one of the external fuel tanks using a connecting sleeve or with a union connected to fuel supply system of the tank from additional fuel barrels (figure 1). Fuel begins to flow, depending on the installation option, either into one of the external fuel tanks or into the fuel supply system from additional fuel barrels. As the tank runs out of fuel, the system begins to feed the exhaust gas from the engine to the fuel tank to prevent the explosion of fuel vapors. The system consists of a fitting connected to the exhaust system of the armored vehicle, by means of a pipeline, a flame arrester, a valve for relieving excess pressure in the tank and an emergency tank discharge device (Fig. 1).

Making part of the structural elements of the combined device hollow and collapsible allows them to be compactly installed when the device is moved to the position for transportation. The compact placement of the combined device on the vehicle during transportation allows, due to the possibility of placing an additional fuel tank in place of the log for self-retrieval, to increase the vehicle's cruising range and to ensure its protection by the self-retrieval structure elements.

Reducing the labor intensity of installation and dismantling is provided due to the possibility of gripping and carrying the device by one person instead of two and excluding preparatory work on leveling the ground (when using a device for self-recovery of a tracked vehicle).

Expansion of technical capabilities when using a combined device for self-recovery of a tracked vehicle is provided due to the possibility of turning (changing direction) in the process of leaving a difficult-to-pass section of the road due to the installation of at least one of the removable supports on each track, which allows the tracks to work independently. from a friend in the process of self-extraction (Fig. 3).

Installed in the ground, the left or right integral tubular part can be used as a fixed support for self-pulling of the vehicle (Fig. 4).

Expansion of technical capabilities is also provided due to the possibility of using a similar design of the device not only for self-pulling of a tracked vehicle, but also due to the use of an additional fuel tank in the design, it helps to increase the range of the tracked vehicle, while making the side ribs of each prismatic structure commensurate with the width of the wheels.

The use of the invention will increase the cross-country ability and the power reserve of tracked vehicles.
