The invention relates to transport machinery, directly to the device that provides increased permeability of the vehicle in conditions of soils with low bearing capacity, and can be used on difficult roads and terrain for self-recovery stuck vehicles tracked or wheeled vehicle.

A device for self-recovery tank (see [1], pp. 576, 577), consisting of a beam adjacent to interacting with the ground external surfaces of the elements (caterpillars) of the mover of the vehicle and fixed to them by means of kinematic relations (with cables). The beam is set perpendicular to the longitudinal axis of the propulsion unit, to which the ends of a log placed on the sites (links) of caterpillars, arranged opposite each other on either side of the longitudinal axis of the propeller. When you drive the crawler log hooked over the ground and the tank moves relative to the ground.

The disadvantages of the known devices for self-recovery tracked vehicles are a significant mass of logs, insufficient strength due to the inconsistency of its physical and mechanical properties. For example, the density (weight) and strength of wood depend on moisture due to the hygroscopic properties of wood. Reduction firmly�t also contributes to the presence of defects in the wood. In addition, wood is easily ignited and capable to rot from moisture. The variability and wide range of tensile strength of wood, depending on various factors reduce the reliability of the device for self-recovery as a whole.

The disadvantage of logs are also substantial work in preparing the vehicle to samovytaskivaniya due to the fact that for smooth stacking of logs under the tracks of the vehicle (avoid damage to the logs), be sure to level the ground for the entire length of the log in the place of installation, in addition to carrying logs requires at least two people.

Due to the large length of the beam occupies a lot of space on the vehicle. This creates additional inconvenience during transportation.

When using logs, you cannot crease (direction of departure) tracked vehicle in the shortest direction to the ground with the required bearing capacity.

The rounded shape of the logs does not allow him to cling to firm soil.

Another drawback of the log is the impossibility of its application in a vehicle with wheeled running gear.

It is also known a means of increasing the permeability of cars operated in off-road conditions presenting with�Oh antiskid diamond pads (see [2], p. 121), who put on the drive wheels car is stuck and fixed by means of chains.

Design flaw diamond pads is that the edges of the lug (diamond ledge pads) made a console (not supported, for example, struts), and the strength of the ribs is achieved with a significant thickness, which leads to the increase of the weight of the device.

From the source (see [2], p. 120) known means of increasing the permeability of cars, increasing the area of contact with non-cohesive soils (loose sand, waterlogged soils), made in the form placeway chain, which consists of stamped plates (PLIC) with well-developed supporting surface, connected by a chain or other similar connections.

Design flaw the pressed plate is increased weight, since edges that perform the function of the lugs, a console made and their durability is achieved with a significant thickness.

From the source (see [2], p. 88) known wheel tractor "Universal-3", made with lugs that are part of the wheel, the ends of which are wedge-shaped for a better grip with the ground.

The disadvantage of this device is the impossibility of dismantling the wheel lugs without thereby limiting its scope.

Challenge us�Mr sage invention is to provide a construction of device for self-recovery vehicle free from the above drawbacks.

The technical result of the present invention is to reduce the size and weight of the device for self-recovery vehicle, increase reliability, ease of use, reducing the complexity of Assembly and disassembly, the expansion of technology.

The technical result of the invention is achieved in that the device for self-recovery of the vehicle is removable mounted on the outside of the ground, facing each other, portions of the outer surfaces cooperating with the ground elements of the mover of the stuck vehicle, symmetrically located on either side of the longitudinal axis of the propeller, and fixed on the above-mentioned elements by means of kinematic linkages with the possibility of coupling with the ground during movement of these elements relative to the vehicle, according to the invention made in the form of at least two rigid hollow prismatic structures with a cross-section in the shape of a triangle, with a flat and/or ribbed side surfaces, with straight and/or curved edges, each on a respective side of the mover of the vehicle has a lateral support surface, articulated through �animationsa relations with the outer surface interacting with the ground element mover, resistant side surface that is in contact with samovytaskivaniya with the ground is made of solid and/or perforated, and the third side surface formed by the spacer element or elements, wherein the length of the lateral edges of each of the prismatic structures commensurate with the width of cooperating with the ground of the corresponding elements of propulsion.

In addition, the prismatic structures can be performed with the possibility of placing one inside the other and attachment to this form in the vehicle.

In addition, at least one of side surfaces of each of the prismatic structures, in addition to resistant, can be performed with the aperture.

In addition, the reference side surface of each prismatic structure, or a portion of the support side surface may be concave.

In addition, the reference side surface of each prismatic structure, or a portion of the support side surface may be formed with relief, partially or completely mimic the outer relief surface interacting with the ground element of the propulsion of the vehicle with the interfacing of these surfaces.

In addition, the cross section can be made variable along the length of the prismatic structure.

In addition, the prismatic structures may �be made collapsible.

The claimed technical features essential, as they affect the technical result achieved.

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

Device for self-recovery of the vehicle 1 (Fig.1, 2, 6, 7) is removable and is installed on the outside of the ground, facing each other, portions of the outer surfaces E (Fig.1, 6, 12) cooperating with the ground elements 2 (Fig.2, 3, 6, 7, 12) mover of the stuck vehicle 1, symmetrically located on either side of the longitudinal axis of the propulsion unit mounted to the structure 2 by means of kinematic relations 3 (Fig.3, 6, 7) with the possibility of coupling with the ground during movement of the element 2 relative to the vehicle 1.

Element 2 of the propulsion device, interacting with the ground, is the caterpillar when using the device for self-recovery of the tracked vehicle and the wheel - when using the device for self-recovery wheeled vehicle.

As the kinematic relations 3 can be used�s, for example, chains, ropes, tightening elements (lanyards), etc.

Device for self-recovery vehicle 1 is in the form of at least two rigid hollow prismatic structures 4 (Fig.1, 2, 3, 6, 7) with the cross-section in the shape of a triangle, with a flat and/or ribbed side surfaces And To (Fig.3, 4, 5, 6, 12) with straight-line L (Fig.4) and/or curvilinear M (Fig.4, 8) ribs. Each prismatic structure 4 located on the respective side of the mover of the vehicle 1, has a lateral support surface W (Fig.3, 4, 5, 6, 12), articulated through kinematic relations 3 with the outer surface E of interacting with the ground element 2 of the propeller, the thrust side surface And (Fig.3, 4, 6) in contact with samovytaskivaniya with the ground is made of solid and/or perforated, and a third side surface (Fig.3, 5, 6) formed by the spacer element 5 (Fig.4) or elements 5 (Fig.5), the length H (Fig.2, 7) of the lateral edges L (Fig.4) of each prismatic structure 4 is commensurate with the width P (Fig.2, 7) cooperating with the ground of the respective elements 2 mover.

The spacer 5 (Fig.4) or elements 5 (Fig.5) serves(at) to impart strength and rigidity of the prismatic design 4.

Prismatic structure 4 with a predominantly flat sides can be accommodated within one another (Fig.11) and fixed in this form in the vehicle 1, for example, pressing the inner through the outer prism of a single device for fastening to a vehicle, made ensuring compactness of layout, as well as a decrease in the number of fasteners on the vehicle.

At least one (for ease of attachment to the vehicle) of the side surfaces of each of the prismatic structures 4, in addition to resistant And can be performed with the aperture P (Fig.4). The presence of openings in the lateral surfaces W, prismatic structure 4 can reduce its weight, to facilitate cleaning of dirt after use, to ensure the convenience of mounting on the vehicle and ease of gripping hands.

For more intimate contact of the support side surface W hollow prismatic structures 4 elements 2 (e.g., wheels) of the supporting lateral surface can be concave (Fig.4), and to reduce the mass of resistant lateral surface And prismatic structures 4 may be formed perforated (Fig.4).

Prismatic structure in concrete execution can be made of welded steel sheets.

Specific performance (Fig.12) to ensure the best pairing of the reference side surface W hollow prismatic structures 4 with the surface E of the element 2 (for example, the surface� link tracks with grousers) supporting the side surface of W is made partially or completely replicate the topography of the outer surface of element 2.

Specific performance (Fig.8, 9, 10) prismatic structures may be formed with a variable cross section (G-G, d-D) in length.

Prismatic structures can also be made collapsible, for example made of three separate sheets forming the respective side surfaces, rigidly interconnected, for example, fulfilled in them through eyelets fastened, for example, fingers (axes).

Hollow prismatic structures may be formed with flat and/or ribbed side surfaces, with straight and/or curved edges, with a spacer element or elements, if the cross section of the prismatic structures on the element(s) form the other two sides of a triangle shape as a triangular profile has an increased lateral stiffness and reduces the weight of the device.

Perform resistant side surfaces of the prismatic structures perforated reduces their weight, while ensuring their durability. The strength of the perforated side (sheet) with a linear decrease in total width of cross-section (through holes) offset by the increase in the thickness of the sheet with a quadratic increase in strength, while the calculations show that it is possible to reduce the weight of the sheet by approximately 13%. The soil passes through the small �TVersity perforation resistant surface and functions as a positive stop.

The self-recovery device of the vehicle operates as follows. In the process of self-recovery vehicles 1 connection, 3 transmit the pulling force from the propulsion elements 2 hollow prismatic structures 4, which are embedded in the soil and create a support for the propulsion of the vehicle 1, provide effective traction and the vehicle 1 moves relative to the ground.

The reliability of the device is achieved through the use of more durable (in comparison to wood - using logs) material for the manufacture of a device, such as a metal.

Reducing the size and weight of the device for self-recovery tracked vehicles is provided by reducing the length of the device (length commensurate with the width of the engine of a crawler vehicle, to a length commensurate with the width of cooperating with the ground element, with the width of the track link).

Weight reduction also contributes to the implementation of the prismatic structures are hollow, they are resistant side surfaces is perforated, and the other of the side surfaces with openings.

The execution of the prismatic hollow structures, if necessary, allows for the use of the device for self-recovery tracked vehicles p�smectite them in the transverse direction of the additional element or elements to increase the area of the bearing surface (or bonding surface), setting the specified(s) element(s) in each of the prismatic structures individually or, using(s) item(s) that connect(s) prismatic structures with each other, and when using the device for self-recovery wheeled vehicle - to place additional elements in each of the prismatic structures separately.

Ease of use provides a more compact placement of the device on the vehicle during transportation due to the possibility of placing one of the prismatic structures inside another, as well as due to the possibility of the prismatic structures collapsible.

Reducing the complexity of Assembly and disassembly is provided by the possibility of capture and transportation of the device by one person instead of two and exceptions preparatory work for the leveling of the ground (when you use the device for self-recovery tracked vehicles).

The expansion of the technical capabilities when using the device for self-recovery tracked vehicle is provided by the possibility of implementation tuck (change of direction) in the process of leaving impassable section of the road due to the installation of at least one prismatic structures each huseni�, allowing the crawlers to work independently from each other in the process of self-recovery.

Facing into the soil adjacent the side surfaces of the prismatic structures, forming a pointed corner, allow for a better grip, penetrating into a dense soil.

The expansion of technology is also enhanced by the possibility of using a similar design of the device not only for self-recovery tracked vehicles, but also wheeled vehicle while performing a side edge of each of the prismatic structures commensurate with the width of the wheels.

The use of the invention allows to increase the permeability of wheeled and tracked vehicles in difficult places.
