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.

The 152-mm 2S19 Msta-S howitzer for firing with separate loading ammunition is known (see the popular science magazine Technique and Weapons, No. 6, 1996, p. 29, publisher of AviaKosm JSC) containing a tracked chassis , a tower mounted on a rotary support device of the chassis. The control department and the weapons department have a single working space and are located in the chassis and turret. The undercarriage consists of a caterpillar mover and suspension. In the bow of the chassis is the driver’s workstation, the rest of the crew are in the tower, where the main armament is installed, consisting of a 152 mm artillery gun and a transportable ammunition for the gun, a filtering and ventilation unit. The engine-transmission compartment with the gearbox to the caterpillar mover is located in the rear of the chassis, in an isolated compartment. The tower is made with the possibility of circular rotation in the horizontal plane. A hydraulic system is installed on the tower floor to service the loading systems of the gun mount. The power supply to the control units consists of four rechargeable batteries installed in the chassis of the chassis, the recharging of which is provided by a generator mounted on an intermediate gearbox kinematically connecting the main engine with gearboxes. The fuel system serving the main engine provides a range of 500 km for self-propelled howitzers. The total mass of the equipped car is 42 tons.

The disadvantages of this design are:

- heavy weight of the machine as a whole;

- the caterpillar mover of the suspension system consists of 12 track rollers with torsion bar suspension and additional hydraulic shock absorbers for the front and rear rollers, the weight of which is 8.7 tons;

- aft location of the engine compartment, requiring a long kinematic connection in the form of a lever system located on both sides of the chassis for the entire length of the machine to the control levers of the driver.

Also known is the Dana combat vehicle with 152 mm artillery (see ISBN Book 0710 6179 09; 1998-99, “Janes”, 920 pages, p. 658), consisting of a chassis with an 8 × wheel arrangement 8 and single-wheel wheels, with a slewing ring for the main armament, a complex of fire control from it and portable 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 there are two more jobs. In the chassis housing on its bottom there is a mechanized installation for shells and charges with the vertical installation of 40 pieces of shots in them. The tower of circular rotation in the horizontal plane, depending on the angles of vertical aiming, is made with a sector rotation: when shooting from closed positions, the turret rotation is ± 45 °, and when firing direct fire it is ± 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 car 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 are:

- limited firing angles, especially from closed positions, which reduces the combat effectiveness of the machine;

- the location of the main engine in the stern, requiring a long kinematic connection in the form of lever systems;

- the design of the outriggers, which does not allow to increase the supporting dimension of the machine, necessary for stability when firing with a circular rotation of the turret within the sector of positive vertical gun aiming angles;

- the remote (external) arrangement of the gun leads to depressurization of the reserved internal volume when transferring a shot to the loading line from ammunition located in the machine’s body;

- Small portable own combat set of shots to the gun;

- base units of the automobile chassis - foreign.

Foreign analogues are open-type installations and have limited firing angles, as a result of which they have low combat effectiveness and are vulnerable to various weapons.

The closest to the claimed invention in terms of essential features is a RM-70 combat vehicle for firing 122 mm rocket shells, developed on the basis of an automobile chassis with heavy-duty tires and an 8 × 8 wheel arrangement (ISBN 0710 6179 09; 1998-99 , "Janes", 920 pp., Pp. 783-785). The machine is made on the basis of a Tatra T-930-3 automobile chassis with a 12-cylinder diesel engine with a capacity of 365 hp located under the cab. The chassis contains an armored cabin mounted on a frame equipped with a transverse base of low height for the installation of a slewing ring. On top of the slewing ring mounted weapons in the form of a launcher for rockets of 122 mm caliber. Behind the cabin on the base, along its length is a transportable ammunition of 40 rounds. The diameter of the slewing ring does not go beyond the overall dimensions of the machine, and its vertical axis is located above the fourth axis of the wheelset, allowing you to create a vertical guidance angle from 0 ° to + 55 ° with a horizontal rotation angle to the left - 125 ° and to the right - 70 ° . The crew of 6 people. The mass of the equipped combat vehicle is 25.3 tons. The maximum speed is 75 km / h.

The disadvantages of the closest analogue are:

- low load capacity of the used chassis;

- insufficient maximum speed in transport position;

- insufficient diameter of the slewing ring, which does not allow the installation of weapons of larger caliber;

- base chassis - foreign.

The problem to which the invention is directed, is to create a mobile modern self-propelled artillery gun of caliber 152/155 mm 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 an object of armored vehicles containing a chassis mounted on its base frame, an armored cabin, an engine under it, a base with a slewing ring and main armament, a fire control complex from it and ammunition carried,

- on the base around its perimeter installed side and roof, forming an onram hull;

- the roof is made with an opening for a slewing ring;

- a turret with main armament, for example, an artillery gun of caliber 152/155 mm, is installed on the rotary support device;

- the internal volumes of the onam corps and towers form a single sealed fighting compartment;

- on the base, on the outside of the on-ramp hull, outriggers are installed whose contact spot with the ground when firing the object is located outside the aft and sides of the object;

- the object is made on the basis of a domestic automobile chassis with a wheel arrangement of 8 × 8 and single-wheel wheels of the KAMAZ-6560 type;

- outriggers are made in the form of plates and pivotally mounted on the base, one in the stern, two on the sides of the machine, with a preliminary rotation in the horizontal plane of 45 ° when installed on the ground.

In the object of armored vehicles with a wheeled chassis, a new set of structural elements, as well as the presence of connections between them, allow, in particular, due to:

- execution of the base with the sides and roof installed along its perimeter, forming the ramparts, install a circular circular base tower in the horizontal plane from a domestic 2C19 howitzer with a 152 mm barrel gauge, or 155 mm barrel caliber on a KAMAZ-6560 automobile chassis of domestic manufacture;

- performing a roof with an opening for a slewing ring, install a horizontal rotation tower horizontally on a wheeled chassis;

- installation on a turntable of a turret with the main armament — an artillery gun of caliber 155 mm; to manufacture products for foreign customers of armaments, caliber 152 mm — for a domestic customer of armaments;

- fulfillment of the internal volumes of the onam corps and tower, forming a single sealed fighting compartment, rationally organize the fighting compartment of the armored object with the most comfortable living conditions;

- installation on the base, outside the on-ramp hull, outriggers, a ground contact spot when firing which is located outside the aft and sides of the object, unload the chassis and give the product the necessary stability by transmitting force effects through the supports directly to the ground;

- implementation of the facility on the basis of the domestic automobile chassis of the KAMAZ-6560 type to reduce the length of the kinematic connection, weight and cost of manufacturing the product;

- implementation of outriggers in the form of plates pivotally mounted on the base, one in the stern, two on the sides of the machine, with a preliminary rotation in the horizontal plane of 45 ° when installed on the ground - increase the dimensions of the product necessary for stability when firing large-caliber shells .

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

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

figure 2 is a top view in a transport position;

figure 4 is a front view in a transport position.

The object of armored vehicles on a wheeled chassis, for example a 155 mm self-propelled howitzer, contains a domestic automobile wheeled chassis 1 (Fig. 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 with inspection hatches 5, an engine 6 with a transmission 7 and a suspension system 8, a base 9, a pivoting device 10. A turret 11 with main armament - 155 mm artillery 12 is installed on the pivoting device 10 (Fig. 1, 2, 3, 4), a complex of fire control from it and carry first ammunition (not shown). The base 9, installed along its entire perimeter of the bead 13 and the roof 14, form an on-wall hull 15. A hole of an increased diameter is made in the roof 14 for mounting the slewing-rotary device 10. The internal volumes of the on-hull 15 and turret 11 form a single sealed fighting compartment, in which combat crew of the gun installation, consisting of 4 people, placed additional fuel tanks, batteries, individual spare parts, hydroelectric station (not shown). The power plant is driven by the free output shaft of the power take-off of the KAMAZ 6560 chassis.

The barrel of the artillery gun 12 in the stowed position is mounted by elements of the stowed device 16.

On the basis of 9 of the oil casing 15 (Figs. 1, 2, 3), outriggers are mounted pivotally - base plates 17, 18, in the amount of 3 pieces, two of which - 17 are installed on the sides 19 of the oil casing 15, and one - 18 There are 20 products in the stern. The plates 17 are pivotally mounted on the on-frame housing 15 with the help of a rotary pedestal 21 with preliminary rotation in a horizontal plane of 45 ° when installed on the ground. Lowering and raising the base plates 17, 18 is carried out using hydraulic cylinders 22, powered by a hydraulic station. The spot of contact with the ground when shooting the object is located outside the stern 20 and the sides 19 of the object.

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

The device operates as follows.

The object of armored vehicles, for example 155 mm self-propelled howitzer, goes to the firing position. In the stowed position, the artillery gun 12 is fixed using the camp mount device 16, the inspection hatches 5 are raised and secured relative to the cabin 4 (figure 1). Remote base plates 17, 18 are raised and secured by fastening elements (not shown) relative to the on-board building 15. To transfer the object from the stowed position to the combat position, inspection hatches 5 in the cabin 4 are automatically closed and locked and the artillery gun barrel 12 located in the marching device is unlocked mounts 16.

Remote base plates 17, 18 are unlocked and lowered to the ground, automatically turning off the sprung running system of the machine due to the operation of hydraulic cylinders 22, while for base plates 17 it is necessary to first unfold the cabinet 21 in a horizontal plane away from the longitudinal axis of the machine by 45 ° and lock it.

At the time of firing, the force from the recoil of the barrel of the artillery gun 12 is transmitted to the ground through the base plates 17, 18, bypassing the frame 3 of the chassis 1 of the self-propelled howitzer. After the shooting is completed, the support plates 17, 18 are automatically lifted, with the subsequent turning to the stowed position of the pedestal 21 and locked using the hydraulic cylinders 22. The barrel of the gun 12 is placed in the camp mount 16 and locked. Hatches 5 in cabin 4 open and lock in a marching manner.

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

The base plate 18 with hydraulic cylinders 22 is used with a domestic military tracked vehicle 2C5.

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.

An example of a specific implementation.

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