Description

 The invention relates to armored vehicles, and more specifically to lightly armored combat vehicles of infantry and landing.

 The BMP-1 [l] infantry fighting vehicle is known, which is armed with a 73-mm smoothbore gun for an active-jet shot, a 7.62-mm machine gun coaxial with the gun, and a launcher for PTUPC. BMP-1 has an armored hull and a tower, which are used to place and protect the crew, weapons, ammunition, units and mechanisms of the machine from damage by enemy fire. The tower is mounted on a ball support above the opening of the turret sheet of the roof of the housing. The upper shoulder strap of the ball bearing is bolted to the bottom sheet of the tower, and the bottom to the ring undercut of the turret sheet of the hull. The hinge is attached to the tower with a floor hanger. The suspension consists of four ribs, an arm and two rods.

 On the turret plate of the casing there is an annular duct through which air from the shaft of the intake pipe enters the propulsion system.

On the basis of BMP-1, a whole complex of armored vehicles was created:
- BMP-1PG - with the additional installation of a grenade launcher on the tower;
- BMP-1K - with equipment of workplaces for officers;
- BMP-1KSH - with the installation of a telescopic antenna mast device in the tower instead of a gun;
- combat reconnaissance vehicle BRM-1K;
- armored recovery vehicle BREM-2;
- mobile reconnaissance points PRP-3 and PRP-4.

 The disadvantage of BMP-1 is the low efficiency of defeating light armored vehicles, manpower and unarmored equipment from a 73-mm gun. Also, the armament complex does not provide self-defense against attacking air assets.

 Known infantry fighting vehicle BMP-3 [2], the layout of which differs from the layout BMP-1. In the front of the hull are the jobs of the driver and two paratroopers, machine gunners, in the middle of the hull is the combat, and behind it - the landing squad.

 The base of the fighting compartment is a double tower, which houses a 100-mm gun - a launcher for firing high-explosive and guided projectiles, a 30-mm automatic cannon and a coaxial 7.62-mm machine gun, solving a wide range of fire tasks. The tower with the help of a ball epaulette is mounted on a turret sheet of media. The floor suspension is made of rods and carriers mounted on the tower. BMP-3 floor suspension is similar to BMP-1, only instead of ribs, to reduce weight, inclined rods are installed - carrier.

 The disadvantage of the BMP-3 combat vehicle is the impossibility of rearranging its fighting compartment with the existing armament complex to old-generation combat vehicles with outdated weapons; the efficiency of the BMP-3 infantry fighting vehicle is significantly enhanced by the use of anti-tank guided missiles for firing from a 100-mm gun , the length of which is approximately twice as high as high-explosive fragmentation rounds. The use of guided shots increases the altitude dimensions of the fighting compartment, as a result of which it becomes unsuitable for use on BMP-1, BMP-2, and BMD vehicles.

 The objective of the invention is the creation of a combat vehicle with a universal fighting compartment, which could be rearranged on carriers of other combat vehicles that do not have enough elective weapons, which ultimately leads to an increase in the efficiency of the whole machine.

 The problem is solved in that in a combat vehicle containing a carrier and a fighting compartment with an armored hood and a suspension of the floor, in which the cannon is located - a launcher, an automatic gun and a machine gun, as well as a deployment system, supply of ammunition and fire control, and installed using a ball shoulder strap on turret sheet of carrier; adapter ring is located between ball shoulder strap and carrier. The floor suspension is made with length-adjustable rods and carriers. In the walls of the armored hood installed bushings for mounting removable pads. The adapter ring is provided with cylindrical protrusions. One protrusion is located in the opening of the turret carrier sheet, and the other interacts with the lower linear ring. The adapter ring is configured to allow air to flow inside the carrier.

 The proposed technical solution is illustrated by graphic materials. Figure 1 shows a General view of an infantry fighting vehicle with a fighting compartment mounted on a carrier using an adapter ring. Figure 2 shows the attachment of the fighting compartment on the media with the adapter ring in the context. Figure 3 is a section of the transition ring, providing the passage of air flow from the air intake device into the carrier, to the propulsion system. Figure 4 is a view of the fighting compartment from above. Figure 5 - design of the suspension of the floor. Figure 6 - site for adjusting the length of rods and drove the suspension of the floor.

 The bottom sheet of the armored cap 1 (FIGS. 1, 2) is fastened to the upper running ring 2, and the lower running ring 3 is installed in the undercut of the transition ring 4 and is held from offset by the protrusion "a". The lower running ring 3 and the adapter ring 4 are fixed with bolts 5.

 The adapter ring 4 is mounted on the turret sheet 6 of the carrier 11 (Fig. 1) and secured with bolts 7. From the shift during firing, the adapter ring 4 (Fig. 2) is held by a cylindrical protrusion "b", which enters the opening of the turret sheet 6. The adapter ring 4 has ribs 8, on which an armor screen 9 is installed to protect the ball epaulettes from shells and fragments.

 The bronekolpak 1 (Fig. 8) can be mounted on the adapter ring 10 having an internal cavity "c" for air flow from the air intake device 12 (Fig. 1) of the carrier 11 to the propulsion system. Armor screens 9 are screwed to the outer surface of the transition ring 10 (FIG. 3) by means of bolts 13. The lower running ring 3 is installed in the undercut of the ring 14.

 In addition to removable armor shields 15 (Figs. 1, 3, 4), depending on the combat missions performed, the armored hood 1 can be equipped with armored plates 16 (Fig. 4), fixed with bolts 13 and bushings 17 on the walls of the armored hood 1.

 To reduce the nomenclature of the adapter rings when installing the fighting compartment on carriers having different body heights, an adjustment of the floor suspension (Fig. 5) in height is provided. Rods 18 and carrier 19, mounted with brackets 20 on the upper running ring 2, have threaded rods 21 (Fig.6). One end of the stud 21 is wrapped in a rod 18 or carrier 19, and the other end is in an adapter 22 pivotally mounted in the bracket 23 of the floor 24. To eliminate self-loosening, the threaded ends of the studs 21 differ in pitch.

 Thus, the proposed technical solution made it possible to increase the efficiency of the old generation infantry and assault vehicles by staging them using transition rings of a modern fighting compartment equipped with removable armor plates and an adjustable floor suspension.
