The utility model belongs to the field of transportation, self-propelled vehicles, to structural elements of bodies, their parts and assemblies, namely to mudguards.

The performance of service-combat tasks in the areas of military exercises and especially in the areas of hostilities require constant redeployment to maneuver forces and means to gain an advantage over the enemy, as well as to avoid possible losses or reduce them. Trucks are the main means of transport for the transportation of resources, including in the area of military conflict today. On the other hand, up to 30 percent of resource losses are associated with partial or total damage to automobile equipment as a result of enemy attacks on convoys or individual vehicles to destroy manpower or seize valuable cargo (1). As a rule, in order to stop the equipment, the firing is carried out with small arms, and with this placement of the column, when the density of fire is maximum, the firing sector is minimal, that is, from the front and rear, namely, on the driver, personnel in the body, wheels and engine (11.

Based on the fact that the personnel in the cab or the body of the truck can quite easily strengthen personal protection with bulletproof vests, separate armor plates, which are also used to book the front part of the car, where the engine is located, then the wheels, especially the rear (based on the firing tactics specified in (11 ), is the most vulnerable place of a truck for taking it out with bullets from small arms.

At the same time, today there are a number of non-standard designs of wheels, tires, tires and devices for protecting the wheels of a truck, among which: a wheel in a wheel И(2| - an internal rigid insert in the form of a ring 3 of two halves made of fiberglass (plastic), which is attached on the disk and on which a tire is mounted on top, which allows for further movement in the event of a punctured wheel. The disadvantage of such a design is that the contact area with the road of such a wheel in a punctured state becomes smaller and at high speed it is difficult and dangerous to drive the car. Such designs are used mainly for special personal transport vehicles that are guarded and driven by ace drivers.In addition, the higher the weight of the vehicle, the higher the balancing requirements and the more difficult the tire installation;

Riai's version (2, 3, 4 | - consists in using a tire with an increased thickness of rubber on the sides

With a reinforced frame. The main disadvantages: the high cost of tires (by 20-30 9o), which have excessive weight, which reduces the dynamism and service life of the suspension; installation requires special equipment, the car must also be equipped with a tire pressure sensor and a stability control system. Used on passenger cars and light trucks; chemistry from the inside (21 - when the tire is damaged, the internal hermetic composition is blown out through the opening, which plugs the hole. Such tires were used only on government cars and were not used in mass production; airless tires |2| - a recent development, used on military armored cars and small equipment (quadricycles, forklifts). The disadvantages of such tires include |І5)І: high cost, low load capacity, impossibility of off-road use; armored canopies (6) - used on armored vehicles for the lateral protection of wheels, in two versions: as a solid armored plate that prevents movement on different types of terrain, and in the form of separate plates that are fixed on a rubber base, which requires special technologies when production Both options are used on armored vehicles and have a high cost due to the cost of special alloys of armor plates and technologies, and have difficulties in mounting.

The given examples are not suitable to implement acceptable protection of the truck without changes in its technical or dynamic characteristics.

The closest analog in terms of features to the useful model is the I7, 81 mudguard, which consists of a sheet part (directly a mudguard) mounted behind the wheels of the car perpendicular to the road surface. The disadvantage of this design is that it is intended only to prevent the contact of the car's structural elements and other road users with dirt, snow, crushed stone, water and other objects flying out from under the wheels and will not provide protection against bullets and fragments.

The basis of a useful model is the task of creating such a structure that will protect the rear wheels of a truck from bullets and shrapnel and can be used on trucks without significantly reducing their dynamic characteristics, including when driving in rough terrain (off-road).

The problem is solved by the fact that the improved mudguard of the truck 60, which is attached to the frame of the truck, according to the useful model, from the side

of the opposite wheel, additionally reinforced by a system of iron chains, the upper edge of which is attached with the help of rigging carabiners to the frame near the place of attachment of the mudguard, and its middle part and lower edge is attached to the technological holes made in the mudguard of the truck.

The essence of the useful model is to strengthen the mudguard of a truck by attaching a system of iron chains to it.

The drawing shows a system of iron chains 1, which consists of vertically arranged chains 2 of a certain number superimposed on the entire width of the mudguard C of the truck from the side opposite the wheel.

For reliable fixation (and to avoid overloading the mudguard), the iron chain system 1 is attached with its upper edge to the frame 4 near the place of attachment 5 of the mudguard of the truck, to avoid longitudinal oscillations, the middle part and the lower edge are attached to the technological holes 6 made in the mudguard of the truck car

Such fastenings are carried out with the help of rigging carabiners 7.

Vertically located chains 2 of the iron chain system 1 with the help of rigging carabiners 7 are fixed from above, in the middle and below by three horizontal chains 8 to avoid transverse vibrations during the movement of the truck. In addition, the vertically located chains 2 are fixed in staggered order with each other using plastic ties 9 (cable binders) to avoid discrepancies.

The use of an improved mudguard of a truck will prevent bullets and fragments from hitting the wheel of a truck behind and leave the dynamic characteristics of the truck unchanged and, as a result, serviceability and reliability, which in turn will ensure the preservation of resources, as well as the life and health of personnel.

Thus, this design is more effective, as its cost is low, and the time for installation (disassembly) is minimal. In addition, the system is easily and quickly repairable, the costs of which are also minimal in the dismantled state, it has small overall dimensions, when the truck is moving over rough terrain, the system is almost resistant to longitudinal and transverse oscillations, deviations and remains undamaged when hitting road bumps.
