Description

The invention relates to the field of military equipment, in particular to self-propelled artillery guns, and can be used in the construction of guns on moving wheeled chassis in the ground forces.

Famous Russian self-propelled gun 2S5 for firing ammunition with separate loading (see. Kholyavsky G.L. Encyclopedia of armored vehicles. Tracked combat vehicles 1919-2000 985-13-0035-7; MN: X71 / ISBN LLC Harvest 2001 , p. 196), which contains a caterpillar self-propelled chassis on which an armored casing with a front location of the engine-transmission compartment is mounted, a suspension system with suspension of the artillery shell, a transportable ammunition of shots to it, and also a support-and-fly plate with a hydraulic drive and two hydrocycles AMD to install instruments in the firing position. The suspension system is turned off for the period of shooting.

The disadvantages of this design:

- loading of sockets of the coordinator of shots is not mechanized;

- the engine-transmission department and the department for controlling the movement of the chassis of the object were created on the tank building specialists;

- large metal caterpillar mover;

- small sector angle of horizontal aiming guns;

- insufficient sector angle of the vertical aiming of the guns;

- insufficient set of shots to the gun - 30 shots;

- it is difficult to load coordinator sockets with shots at the extreme corners of the gun’s horizontal aiming;

- insufficient range with a one-time fueling - 500 km;

- low efficiency of the backing plate to turn off the suspension of a part of the running system compared to aiming at extreme angles in the horizontal aiming sector, the axis of which coincides with the longitudinal axis of the machine.

Also known is the Dana combat vehicle with 152 mm artillery (see ISBN Book 0710617909; 1998-1999, "Janes", 920 pp., P. 658), consisting of a chassis with an 8 × 8 wheel arrangement and single-wheel wheels, an armored hull with a stern arrangement of the engine-transmission compartment, a slewing ring for the main armament, a fire control system from it and transportable ammunition. In the bow of the machine there is a control compartment for two workplaces. In the middle part, on the ceiling part of the hull, a rotary support device for an armored turret with an outward-mounted gun and a loading mechanism is installed. Inside the tower near the sides are two more jobs. In the chassis body on its bottom, mechanized laying for shells and charges is vertically installed - 40 pcs. shots. The tower of circular rotation in the horizontal plane, depending on the vertical aiming angles, is made with a sector rotation: when firing from closed positions, the turret's rotation is ± 45 °, and when shooting with direct fire - ± 225 °.

The aft engine has a capacity of 345 hp. The machine is equipped with a filter ventilation device and an air conditioning device. The curb weight of the machine is 28 tons. The maximum speed on the highway is 80 km / h. Cruising range of fuel is 600 km.

For stability in firing shots, the machine has a mechanism for turning off the sprung suspension of the hull relative to the ground in the form of movable support plates with a diametrical form of contact (support) on the ground, which are installed: two in the stern and one on each side of the side in the middle part. The transfer of supports from traveling to combat occurs vertically and parallel to the vertical axis of the tower, without leaving the overall dimensions of the machine.

The disadvantages of this design:

- the base frame of the car chassis is not used;

- kinematic communication from the traffic control compartment to the engine-transmission compartment is located along the entire length of the chassis;

- low carrying capacity of the equipped object - 28 tons;

- insufficient set of shots to the gun - 40 shots;

- complicated mechanized transmission of a shot from the nests of mechanized warheads with two coordinators to the gun loading line;

- insufficient range - 600 km;

- the design of the outriggers, which does not allow to increase the reference dimension of the machine, therefore, the efficiency of turning off the suspension of the housing for the firing period at the extreme corners of the horizontal aiming sector is small;

- base units of the automobile chassis - foreign.

The closest to the claimed invention in terms of essential features is a self-propelled artillery gun containing a base frame, a fighting compartment with a slewing ring, an engine, a running gear, including a wheel propulsion system, a braking system and a spring suspension of wheels, a fire control system and transportable ammunition (Volkovsky N.V. Encyclopedia of modern weapons and military equipment. M.-SPb .: Publishing house Polygon, 2005, p.501-503).

The disadvantages of the closest analogue:

- large dispersion and insufficient accuracy of the hit of a single projectile launched from the launcher at the intended target;

- low load capacity of the applied chassis;

- right-hand turn in the horizontal plane of the launcher of weapons is not equivalent to left-hand turn;

- insufficient power reserve when refueling once;

- there are no additional supports to turn off the suspension of the suspension system for the period of shooting;

- there is no armored protection of transportable shots of the main and additional set;

- there is no mechanization to restart the launcher from the optional kit.

The task to which the invention is directed is to create a mobile modern self-propelled artillery gun, with the installation of 152/155 mm caliber weapons in the rear, on a wheeled chassis of a domestic manufacturer without compromising the tactical and technical characteristics of similar products on a tracked chassis.

The technical result of the present invention is to reduce the weight characteristics and manufacturing costs of the product.

The claimed technical result is achieved by the fact that in a self-propelled artillery gun containing a base frame, a fighting compartment with a slewing ring, an engine, a running gear including a wheel propulsion system, a brake system and a spring suspension of wheels, a fire control system and ammunition

- execution of the manipulator in the form of two pivotally mounted trays - to fire shells of separate loading.

The essence of the proposed technical solution is illustrated by drawings, where:

figure 1 shows a General view of the object of armored vehicles in the transport position, left view;

figure 2 is a top view, with base plates in the working position;

figure 3 is a front view in the stowed position.

Self-propelled artillery, for example a 152-mm self-propelled howitzer, contains a domestic automobile wheeled chassis 1 (Figs. 1, 2) of the KamAZ-6560 type with an 8 × 8 wheel arrangement and single-wheel wheels 2. An armored cabin 4 is installed on the base frame 3 of the chassis 1 inspection hatches 5 that open during the stowed position, the engine-transmission compartment 6, the chassis 7, including the wheel motor 8, the brake system 9 and the spring suspension of the wheels 10.

A sealed hull base 12 is installed on the base frame 3 using a bolt connection 11, made in the form of a pressurized fighting compartment, inside which along its length are mounted a tandem (along the product axis) ammunition rounds in two mechanized stackings with a horizontal arrangement of sockets for the projectile and propellant charge 13 , manipulator 14. The manipulator 14 is made in the form of two articulated trays for the projectile and charge (not shown). The crew 15, consisting of a commander, gunner and operator, is located in the stern of the combat vehicle, on both sides of the manipulator 14. The driver is in an armored cabin 4.

From the end in the aft part of the hull base 12, a hinged hatch 16 is installed for transferring shots to the loading line.

On the roof 17 of the aft part of the armored hull 12, a pivoting device 18 is installed, on which, in turn, armament is installed - a 152-mm artillery gun 19, a fire control complex from it (not shown). The artillery gun 19 is mounted on the machine 20 with the possibility of rotation in the horizontal and vertical planes, rotation on the angular sector in the horizontal plane is due to the rotary support device 18, in the vertical plane - due to the aiming mechanism (not shown) of the artillery gun 19. In the field the position of the artillery gun 19 is fixed by the locking mechanism 21.

Outside, external supports are pivotally mounted on the hull base 12 (Figs. 1-3) - support plates 22, 23 in the amount of 3 pcs., Two of which - 22 - are installed on the sides, and one - 23 - is installed in the stern of the product by type object armored vehicles 2S5. Smaller plates 22, 310 mm, are pivotally mounted on the housing base 12 with the help of a rotary pedestal 24 with preliminary rotation in the horizontal plane by 45 ° when installed on the ground. Lowering and raising the base plates 22, 23 is carried out using hydraulic cylinders 25, powered by a hydraulic station. The contact spot with the ground when shooting the object is located outside the aft and sides of the object, thereby increasing the dimensions of the supporting surface area and the stability of the object itself. Thus, the sector increases the horizontal angle as a whole on both sides of the longitudinal axis of the chassis 1.

The base plate 23 with hydraulic cylinders 25 is used with a domestic military tracked vehicle 2C5.

The main armament of the tower can be made in the form of an artillery gun of caliber 152/155 mm with transportable ammunition.

The device operates as follows.

In the stowed position, the artillery gun 19 is fixed using the locking mechanism 21. The hinged hatch 16 is closed, providing sealing of the hull base 12.

Inspection hatches 5 on the armored cabin 4 are open and locked. Slewing plates 22, 23 are raised and fixed.

Self-propelled artillery goes to the firing position. To transfer an artillery gun from a stowed position to the combat braking system of the undercarriage, the object is stopped: the outer bearing plates 22, 23 are unstopped and lowered to the ground, automatically turning off the sprung suspension system of the machine due to the operation of the hydraulic cylinders 25, and for the supporting plates 22, a pedestal 24 is necessary turn in a horizontal plane away from the longitudinal axis of the machine by 45 ° and lock. Inspection hatches 5 in the cab 4 are automatically closed and locked. The hinged hatch 16 opens to the extreme position. The barrel of the artillery gun 19, located in the marching mount device 21, is unstucked and brought into a combat position, ensuring that the projectile and projectile charge are received from the manipulator 14 and are brought to the loading line.

At the command of the commander, the gunner makes a tip and a shot. Topographic equipment and an automated guidance and fire control system (ASUNO) are installed on the product, which provides for the implementation of an anti-fire maneuver with autonomous determination of current coordinates, automatic calculation of installations for firing from closed fire positions at observable and unobservable targets. Implemented automatic aiming guns and restore aiming after a shot.

At the time of firing, the force from the recoil of the barrel of the artillery gun 19 is transmitted to the ground through the base plates 22, 23, bypassing the frame 3 of the chassis 1 of a self-propelled howitzer.

After the shooting is completed, the base plates 22, 23 are automatically lifted, followed by turning to the stowed position of the pedestal 24 and locked using the hydraulic cylinders 25. The barrel of the artillery gun 19 is placed in the camp mount device 21 and is stopped. Hatches 5 in cabin 4 open and lock in a marching manner.

Self-propelled howitzer leaves the firing position without destroying the pavement.

The layout solution allows you to place any combat module on virtually any car chassis of the required carrying capacity. In our case, this is the KamAZ-6560 chassis.

As a result of the implementation of the proposed technical solution with a new hull base 12, it is possible to carry at the same time 62 shots of separate loading in mechanized stackings for shells and propellant charges, as well as to shoot at sector angles:

- vertically from -3 to + 7 ° in the sector of horizontal angles, from +15 to + 35 ° on both sides of the longitudinal axis;

- vertically from +7 to + 70 ° in the sector of horizontal angles ± 35 °.

Concrete example

At present, individual units have been manufactured that have passed stationary tests.
