Description

The invention relates to armored vehicles, and more specifically to gun installations, placed on the tank chassis.

Known self-propelled gun mount (tank), containing an armored hull, power plant, self-propelled tracked chassis, gun, ammunition and a surveillance and fire control system [1].

The known installation has a tower, the axis of rotation of which is tilted towards its stern. However, this does not adequately protect the tower from defeat in war conditions. In case of damage to the turret or weapon system, the tank must undergo a lengthy overhaul to restore the tank to a combat-ready state.

Known self-propelled gun mount (T-95 tank), containing an armored hull, a power plant, self-propelled tracked chassis, a gun with an automatic loader, ammunition and surveillance and fire control systems [2].

The gun of the installation is located in the turret, and the ammunition and automatic loader in the armored housing of the installation.

Similarly to the aforementioned installation, when a turret or weapon system is damaged, this installation, depending on the degree of destruction, can be brought into operational state only after a long overhaul or decommissioned metal, which significantly reduces the duration of its combat effectiveness.

The aim of the invention is to expand the functionality of the installation and increase its combat readiness.

Mounting the gun system with the ammunition on a removable support frame allows, in case of damage as a result of hostilities, to completely replace it in a relatively short time, thereby reducing the time to bring it into a combat-ready state.

This goal is achieved by the fact that in a well-known self-propelled gun mount containing an armored hull, a power plant, a self-propelled tracked chassis, a gun with an automatic loader, ammunition and surveillance and fire control systems, the ammunition is located in cylindrical containers located on both sides of the gun’s barrel, and the gun with the automatic loader and the ammunition containers are removable, and the containers are equipped with a piece-by-piece feeding mechanism of the ammunition to the automatic loader, made in the form of claimed in containers two-stage spring clips, the stage of larger diameter which is secured on the container, and the smaller diameter step is made adjustable and is connected with the rod having reciprocating movement.

Placing the ammunition in cylindrical containers located on both sides of the gun’s barrel and fixing them with the gun’s barrel and automatic loader on a removable supporting frame allows the crew to be separated from the ammunition and the gun’s loading process and to eliminate the possibility of its explosion inside the installation’s body in case of damage.

Such placement of the ammunition kit, as well as the implementation of it and the gun with a removable automatic loader, allows you to quickly completely replace the gun system with the ammunition when it is hit and, thus, restore the combat readiness of the installation, which significantly increases its functionality.

The presence of single-unit supply of ammunition to the automatic loader located on both sides of the gun’s barrel, and, accordingly, of a double-sided automatic loader, can increase the rate of fire and make more effective use of shells with various striking characteristics.

The invention is illustrated by drawings. Figure 1 shows a General view of the installation, figure 2 and 3 is the same (plan view and rear view, respectively, the rear view is shown without an automatic loader), figure 4 is the position of the containers with ammunition and automatic loader (view And in figure 1 without the upper armored sheet), in figure 5 - automatic loading (type B in figure 4), figure 6 is a transverse section of containers with ammunition (section bb in figure 4), in figure .7 - elements of the system for supplying ammunition to the automatic loader (section G-G in Fig.6), Fig. 8 - fixed position of the ammunition in the container (section DD in Fig.7).

A self-propelled gun installation contains an armored housing 1, a self-propelled tracked chassis 2 with a power unit, a gun 3 with an automatic loader 4, cylindrical containers 5 with an ammunition load 6, a removable support frame 7, on which the gun barrel and ammunition containers are fixed.

In the upper part of the hull there is a rotating armored platform 8 with the ability to rotate 360 °.

On a rotating platform using a swivel joint 9, a removable support frame with a gun and containers with ammunition is fixed. Closer to the edge of the platform, the supporting frame is equipped with a link 10 connecting it to the vertical movement mechanism 11.

The containers have a cylindrical shape and are located in the cells 12 of the support frame in two tiers of two containers in each of them. The containers are located symmetrically on both sides of the gun.

The position of the ammunition in the containers is fixed by means of two-stage spring holders 13 in the form of plates, the larger diameter of which is fixed on the container, and the smaller diameter is made adjustable and connected with the rod 14 of the piece loading mechanism of the ammunition to the automatic loader. The bar has the ability to reciprocate in the longitudinal direction. The lower part of the steps of the smaller diameter of the holders is bent inward, forming stops 15, which hold the damping element 16 and the ammunition shell itself.

The step of the smaller diameter of the holders is equipped with a plate 17, which has an oblique slice on the lower side and interacts with the wedge-shaped element 18 of the mechanism for supplying the ammunition load to the automatic loader. The rod has the possibility of longitudinal reciprocating movements from the drive device 19 and return to its original position using the spring 20. It is equipped with locking sleeves 21, rigidly connected by rods 22, 23 and arcs 24 with wedge-shaped elements interacting with the plates of the projectile holders of the entire ammunition located in each of the 4 containers on both sides of the gun.

At the exit of the shells from the containers, the latter are equipped with guide channels 25 for the oriented supply of shells to the loading machine.

Double-acting automatic loader. Each section of the machine includes a conveyor belt 26 with cells formed by vertical elastic scrapers 27, and a piece-by-piece mechanism for placing shells into the gun barrel, made in the form of a two-arm gripper 28 with fixing elements 29. A scraper 30 is installed in front of the initial position of the cell for loading the gun, removing if necessary, a damping element adhering to the end of the projectile.

Under the lower branch of the conveyor belts of both sections and their lateral sides, guides 31 are installed for moving shells of the second tier along them.

This installation does not have a tower, the crew is in its armored hull.

The proposed installation works as follows.

In preparation for firing, the vertical movement mechanism 11 gives the support frame 7 with a gun 3 and containers 5 with an ammunition 6 small angle of inclination, about 7 ° -10 °. This is necessary for the free movement of ammunition shells in containers and feeding them to the automatic loader. After that, the driven hydraulic unit 19, the rod 14 is moved back. The wedge-shaped elements 18, which are rigidly connected with it by means of rods 22, 23 and arcs 24, interacting with the plates 17, part a step of a smaller diameter of the holders 13, pressing them against the walls of the containers. Once free from holders, the ammunition shells of all tiers in the containers glide down. The shells of the first tier, bypassing the guide grooves 25, fill the cells of the conveyor belt 26 formed by elastic scrapers 27. The rod 14 is returned to its original position by the spring 20. Moreover, the opening period of the step of a smaller diameter holders is designed so that they should already fix the shells that have moved to them upper tier.

At the same time, projectiles can be fed into the automatic loader located on the other side of the gun, followed by the successive laying of shells in the gun barrel from both automatic loaders, which increases the rate of fire of the installation.

Further, the projectile, located in the cell of the conveyor 26 at the starting position, is picked up by a two-arm gripper 28 with fixing elements 29 and is fed into the barrel of the gun. If it is necessary to increase the rate of fire of the shells, the shells are alternately fed into the gun barrel 3 with both grips 28.

After releasing the first cell from the projectile, the conveyor 26 is automatically turned on, which moves the next projectile to its original position. The shells of the second tier, located in the cells of the lower branch of the conveyor 26, moving along the guides 31, rise to the upper branch of the conveyor, from which they are alternately fed into the barrel of the gun 3.

If the damping element 16 is not separated from the end of the projectile when it is fed into the conveyor cells, it will be removed by a scraper 30 when the projectile is fed to its original position.

After the consumption of shells in the automatic loaders, a new batch of shells is fed from containers 5, carrying out the above operations.

Upon detection of the target, the gun’s barrel 3 is induced at it by rotation of the armored platform 8 and the operation of the vertical movement mechanism 11 of the support frame 7 with the gun’s barrel 3.

To reduce the recoil of the gun barrel to the support frame and containers with ammunition when firing the unit, a free rollback of the barrel in the guides of the support frame and a multi-stage damping device (not shown) are provided.

After spending the entire ammunition or in case of damage to the gun system as a result of the battle, the installation is sent to the technical support point, where the gun system and ammunition are completely replaced.

To do this, the hinge joint 9 is disconnected, disconnecting the removable support frame 7 from the stops of the armored platform 8, the link 10 is disconnected from the vertical movement mechanism 11, and a new interchangeable system with full ammunition is mounted in place of the removed gun system.
