Description

The invention relates to the field of military tracked vehicles (VGM) and can be used to develop a low-silo chassis with a high level of crew protection for VGM for various purposes.

Domestic and foreign experience in transport engineering shows that, from the standpoint of maintainability and maintenance, it is economically very profitable to use a single unified chassis to create a family of machines. The use of such a chassis for military tracked vehicles allows you to additionally implement the provision of a single level of mobility and security, necessary for the performance of tasks in the conduct of hostilities.

Known multi-purpose armored tracked chassis [1], made on the basic tank chassis and in this regard, having the level of protection of the crew at the tank level. Such a chassis makes it possible to create a complex of heavy combat vehicles suitable for use in, for example, an autonomous complex of armored tracked vehicles [2], capable of performing autonomous combat operations both on the front line with enemy defenses using anti-tank weapons, and beyond after breaking through the defense . It should be noted that even for a modern tank chassis, the problem of protection against mine action is urgent, since the operation of high-explosive mines leads to deflection of the bottom causing injuries to the crew and disruption of the interaction of mechanisms, and cumulative ones to breaking the bottom with even more serious consequences. The increase in the thickness of the bottom armor does not solve the problem, which, for example, reaches 16 mm on the Chiften tank of Great Britain [3, p. 65].

However, such a heavy tank chassis [1] is impractical to use for the creation of high-altitude military vehicles that are not intended to be used as a means of breaking through defense lines, for example, for deploying anti-aircraft air defense systems [4, 5], self-propelled artillery installations [6] or self-propelled howitzers [7], where lightly armored chassis are traditionally used and the protection of which is sufficient to provide at the bulletproof and anti-shatter level. At the same time, since mine guidance using modern means, such as aviation, can be carried out by the enemy in any zone, the mine protection of the crew and for lightly armored vehicles must be carried out at a high level.

Known object of armored vehicles according to patent No. 2274819 [7], the use of which is intended primarily for self-propelled howitzers of the type "MSTA-S". This object of armored vehicles contains a lightly armored chassis with a hull, a caterpillar mover in the chassis and aft location of the engine and transmission compartment, a weapon armament module made in the form of a tower mounted on a slewing ring with the main armament, fire control complex from it, and transportable ammunition and crew members jobs. Places of crew members are located in an armored module installed in the bow of the hull, in the area between the first and second track rollers, as follows from the description and explanatory materials, and are equipped with a fire control and instrument control system for performing all operations of the armored vehicle.

The use of an armored module ensures the favorable functioning of the crew when firing from a howitzer, eliminating the presence of gas contamination from the propellant of the projectiles and reducing the level of acoustic impact from firing.

The disadvantage of this technical solution is to increase the threat and the degree of mine impact on the crew. This is explained as follows. A significant threat to tracked armored vehicles (previously mentioned on the example of a tank) is represented by anti-tank mines: high-explosive contact actions [8] of type TMK 2, which, when buried or thrown (in the VGM displacement zone), are fired under the track surface when the first track roller, causing not only the destruction of the elements of the chassis, but also the permanent deformation of the tank bottom (in this case, the armored module) in this area with the failure of the driver of the tank (in case of the crew of the armored module), or anti-bottom mines with a contact fuse using a whip antenna, or a non-contact fuse of the magnetic principle of operation [9] like the TM-89 mine. At the same time, anti-bottom mines for guaranteed destruction of the high-altitude mine have a moderator, the presence of which displaces the mine action zone from the front of the high-altitude mine in the direction of the stern to almost the area where the armored module is located according to patent No. 2274819. Thus, the completion of the VGM in full accordance with the location of the crew proposed in the patent No. 2274819 [7] increases the risk of mine impact on the VGM crew of both high-explosive contact mines and anti-bottom mines.

Known self-propelled tracked vehicle SM-100 according to the patent for utility model No. 28343 [10], in which the crew is located in a forward cabin. This machine is taken as a prototype for the claimed technical solution.

This self-propelled tracked vehicle belongs to engineering tracked vehicles, contains crane equipment and a winch, which are located according to a utility model [10. p. 3] on the caterpillar chassis mentioned earlier and described in article [6], which was developed at the Kirov Plant for the Pion self-propelled artillery mount with a heavy 203 mm gun.

In this installation, a long-range 203 mm gun, equipped to increase the firing range with a long gun barrel, is fixed in the aft part to prevent excessive forward projection of the gun behind the chassis body. Otherwise, the mobility of the Peony installation was significantly reduced. However, fixing the gun in the rear of the chassis led to a displacement of the center of mass towards the stern. To adjust the position of the center of mass and ensure a more even distribution of loads on the track rollers in the Pion installation, the lightly armored cabin of the crew members was moved forward (which was repeated on the SM-100 machine) to the maximum possible distance beyond the support surface of the caterpillar mover, and since the maximum angle the slope of the obstacle to be overcome was required to be kept at ~ 30 ° (which in tracked vehicles is determined by the angle of inclination of the front branch of the caterpillar mover and the exception in protrusion of the chassis elements in the area of a given angle), then the cab, which determines the height dimension of the chassis, was raised to a considerable height from the ground level. In addition, in order to adjust the position of the center of mass and evenly distribute the loads on the track rollers, the engine-transmission compartment in the chassis of the Pion installation was moved to the bow of the hull.

The self-propelled caterpillar vehicle SM-100 repeated the considered technical solutions implemented in the Peony installation.

Other components of the lightly armored chassis of the SM-100 machine are a body with a supporting platform for placing a telescopic power manipulator with a rotator (functional module), crew workstations located in the lightly armored control module installed in the bow of the body, a caterpillar mover in the chassis and motor a transmission compartment located directly behind the partition separating the control module from the engine compartment. Additionally, for operator control of the crane in the CM-100 machine, an operator’s cabin is located on the supporting platform.

When using a chassis with the described location of the control module for the VGM, due to the significant extension of the module forward - relative to the supporting surface and upwards - relative to the ground level, the threat of mine impact on the crew is reduced in comparison with the armored vehicle [7], which is the advantage of the chassis.

On the other hand, shifting the control module up from the ground increases the silhouette of the chassis and brings the crew into the area with the highest probability of direct-fire weapons, which is a drawback with respect to military tracked vehicles. In addition, while for the Peony installation, the significant forward movement of the control module and the engine-transmission unit beyond the support surface of the caterpillar mover was an effective tool from the standpoint of the optimal distribution of loads on the rollers, then for the chassis of the SM-100 with a lighter and more distributed length such a technical solution is not advisable due to the occurrence of significant longitudinal vibrations with respect to the center of mass displaced towards the nose s, which limits the speed of movement, and the chassis itself acquires a highly specialized purpose and becomes unsuitable, for example, for anti-aircraft missile defense systems [4, 5].

The disadvantage of the known chassis is the high silhouette, high longitudinal dimensions and limited mobility.

The objective of the present invention is to provide a universal low-silo chassis with increased mobility and protection of the crew from being hit by direct fire weapons and maintaining a high level of protection against mine action.

The technical result achieved by the invention is to reduce the silhouette of the chassis, reducing the level of longitudinal vibrations of the chassis and placing the crew in an area with reduced opportunities for hitting direct fire weapons.

The applicant proposes two options for solving the problem with achieving a technical result.

The task of the first embodiment is solved by the fact that in the chassis for military tracked vehicles, comprising a housing with a bottom and a supporting platform for accommodating a functional module, for example, an weapon module, a motor-transmission compartment (MTO) with a power plant and transmission, chassis, including tracks, drive wheels and torsion bar suspensions with track rollers defining the longitudinal dimensions of the track surface of the caterpillar mover, control module with crew workstations located at the fore These hulls, according to the invention, the control module is made in the form of an armored, located throughout the hull beyond the dimensions of the supporting surface of the caterpillar propulsion superstructure, in which behind the frontal inclined armor plate are located: in the upper part there is a compartment for accommodating crew seats and an instrument complex for controlling the movement of the machine and equipment functional module, in the lower part there is a niche separated from the internal volume of the hull from the side of the stern of the chassis by a step partition, behind the vertical wall of which the chassis of the chassis is the power plant, and under the partition at the sides of the hull - the side gearboxes of the transmission, while the niche is made with the possibility of placing the legs of the crew members in a sitting position, the crew seats are located above the stage of the partition with the minimum possible excess of its level, and crew hatches made on the roof of the superstructure, a set of monitoring devices is located.

The best technical result in this embodiment is achieved when:

- the upper part of each side of the hull, located behind the superstructure and connected with it, is made in the form of a box-shaped frame placed above the caterpillar, the bottom of which performs the function of a fenestrated shelf, while the frame is provided with transverse partitions with the formation of compartments;

- on one of the crew hatches mounted anti-aircraft machine gun installation of the closed type, made with the provision of remote control firing;

- frontal inclined armor plate made with a level of protection from bullets caliber 12 mm;

- in the frontal inclined armor plate there is a window with glass providing bulletproof protection for the crew;

- crew members seats located at the sides of the control module are advanced;

- the compartments of the frame are used to accommodate batteries, spare parts and tools of a military tracked vehicle.

The task of the second embodiment is solved by the fact that in the chassis for military tracked vehicles, a housing with guide wheel brackets, a bottom and a supporting platform for accommodating a functional module, for example, an weapon module, a motor-transmission compartment (MTO) with a power plant and transmission, chassis including tracks, driving and steering wheels and torsion bar suspensions with track rollers defining the longitudinal dimensions of the track surface of the caterpillar mover, control module with workstations the crew located in the bow of the hull, according to the invention, the control module is made in the form of an armored, located throughout the hull beyond the dimensions of the supporting surface of the caterpillar propulsion superstructure, in which behind the frontal inclined armor plate are located: in the upper part there is a compartment for accommodating the crew seats and the instrument complex control the movement of the machine and the equipment of the functional module, in the lower part there is a niche separated from the internal volume of the hull from the side of the rear of the chassis by a step partition, the step of which is placed with the minimum possible excess of the level of the common axis of the brackets of the steering wheels, while the niche is made with the possibility of placing the legs of the crew members in a sitting position, and the crew seats are placed above the partition level with the minimum possible excess of its level, while at the crew hatches, made on the roof of the superstructure, located a set of monitoring devices.

And in this embodiment, the best technical result is achieved when:

- the upper part of each side of the hull, located behind the superstructure and connected with it, is made in the form of a box-shaped frame placed above the caterpillar, the bottom of which performs the function of a fenestrated shelf, while the frame is provided with transverse partitions with the formation of compartments;

- on one of the crew hatches mounted anti-aircraft machine gun installation of the closed type, made with the provision of remote control firing;

- frontal inclined armor plate made with a level of protection from bullets caliber 12 mm;

- in the frontal inclined armor plate there is a window with glass providing bulletproof protection for the crew;

- crew members seats located at the sides of the control module are advanced;

- the compartments of the frame are used to accommodate batteries, spare parts and tools of a military tracked vehicle.

Analysis of the distinguishing features of the proposed chassis according to the first embodiment showed that:

- execution of the control module in the form of an armored, located throughout the body beyond the dimensions of the supporting surface of the crawler superstructure of the superstructure, in which behind the frontal inclined armor plate are located: in the upper part - a compartment for accommodating crew seats and an instrument complex for controlling the movement of the machine and equipment of the functional module, the lower part - a niche made with the possibility of placing the legs of the crew members in a sitting position, provides good living conditions for the crew independently on what equipment or weapons are used in the structure of the functional module. The installation of a partition separating the control module from the internal volume of the chassis housing from the stern serves the same purpose;

- the location of the power plant and transmission in the bow of the hull frees up the volume of the stern of the hull, forming a place for placement in the hull of ammunition, individual elements or equipment of the functional module, requiring an increased level of protection. The same purpose is the use of the compartments of the superstructure frame to accommodate batteries, spare parts and tools of a military tracked vehicle;

- the execution of the step-shaped partition allows rational use of the internal volumes of the chassis of the chassis and the control module, due to which the area under the seats of the crew members, which is not suitable for functional use in the control module, is used to place the side gearboxes of the chassis transmission, and the area in the case behind the vertical wall partitions used to locate the power plant functionally associated with the transmission;

- the placement of crew seats above the (horizontal) stage of the partition with the minimum possible excess of its level ensures the implementation of the superstructure with the smallest possible height dimensions.

The above distinctive technical solutions in the complex allow the crew to move forward beyond the dimensions of the supporting surface of the caterpillar mover, minimizing the effect of mine exposure from contact mines and anti-bottom mines, especially anti-bottom mines equipped with a retarder. On the other hand, such a crew placement (with the smallest possible excess above ground level) reduces the chances of hitting it with direct fire weapons.

The location of the hatches for each crew member on the roof of the superstructure (on the tank) helps to increase the stability of the superstructure to deformations, and the location of the complex of observation devices for the hatches, i.e. in the most elevated area of the superstructure helps to ensure good visibility (at a level not lower than that of the prototype);

- the implementation of the upper part of each side of the hull, located behind the superstructure and connected with it, in the form of a box-shaped frame placed above the caterpillar, the bottom of which performs the function of a fenestrated shelf, while the frame is provided with transverse partitions with the formation of compartments;

- placement of a closed type anti-aircraft machine-gun mount on one of the crew’s hatches, made with the provision of remote control for firing, it is advisable from the standpoint of the possibility of targeted fire by the crew directly from the control compartment;

- the implementation of the frontal inclined armor plate with a level of protection from bullets of 12.7 mm caliber provides a sufficiently high level of crew protection;

- the implementation in the frontal inclined armor plate of a window with glass providing bulletproof protection for the crew, it is advisable from the standpoint of improving visibility to the driver or crew commander, although it reduces the ability to protect the crew from large fragments and 12.7 mm caliber bullets;

- forward shift of the crew members located at the sides of the control module, while maintaining the longitudinal dimensions of the chassis, provides approximately equal ergonomic conditions for all crew members, taking into account the greatest functional workload of the driver.

An analysis of the distinguishing features of the proposed chassis according to the second embodiment showed that the distinguishing features common with the first embodiment have the same effect on the achievement of the technical result, and the cause-effect relationships between the technical result and the distinguishing features are similar.

At the same time, in this embodiment, in comparison with the first, the location of the crew seats above the partition level, which, in turn, is placed with the minimum possible level above the common axis of the guide wheel brackets, allows for even lower crew placement above ground level. However, such a solution can be implemented only with the aft placement of the power plant and transmission in the VGM chassis, which causes a difference between the first and second options.

- figure 10 is an example of the implementation of the inclined armor plate of the control module with a glass window, providing bulletproof protection for the crew.

The low-silo chassis according to the first embodiment (see FIGS. 1-3) contains a housing 1 with a bottom 2 and a supporting platform 3 for accommodating a functional module, for example, an weapon module, a motor-transmission compartment (MTO) 4 with a power unit 5 and a transmission 6, the running gear, including tracks 7, driving wheels 8 and torsion bar suspensions 9, with track rollers 10, the number and location of which determines the longitudinal dimensions (in fact, the length L of the bearing surface “a” of the caterpillar mover), as well as the position of the chassis body and its devices relative to itelno supporting surface (support surface under a crawler understood caterpillars surface contacting with the ground). The chassis is equipped with a control module 11, in which crew seats 12-14 are installed at workplaces. The control module 11 is located in the bow of the hull, in its continuation, and is made in the form of armored, installed in the continuation of the hull in the direction of the bow, superstructure 15 with a frontal inclined armor plate 16, made with a level of protection from bullets of 12.7 mm caliber, airborne armor plates 17 and 18 with the same level of protection and a roof 19. The superstructure 15 is located outside the limits of the supporting surface "a" of the caterpillar mover, which is understood as a complex of mechanisms, including the previously mentioned devices (7, 8, 10) that convert the twisting The second moment supplied through the final drive gearboxes 20 of the transmission 6 into the traction realized by the caterpillar 7, which ensures the movement of the chassis.

MTO in the housing 1 of the low-chassis chassis is located directly behind the superstructure 15 and is separated from the internal volume of the control module of the partition 21, which is made in a stepped form. The horizontally located step “b” of the partition is a support for securing the seats of 12-14 crew members, the upper part “c” of the partition is limited at the top by the level of the supporting platform 3 and is made with a slight deviation from the vertical, providing ergonomic placement of crew members. The height of the superstructure 15 is slightly higher than the height of the sides of the hull 1, because of which the roof 19 of the superstructure is higher than the level of the supporting platform 3. In this regard, since the functional module may not provide complete overlap of the rear of the superstructure protruding above the level of the supporting platform 3 from the stern the chassis, then to ensure guaranteed protection of the crew in this area, the superstructure is also made using the armor plate 22, which is located in the continuation of the upper part of the partition 21.

The protruding stage “b” of the partition divides the internal volume of the control module into a compartment 23 formed in its upper part, which houses the crew seats and the instrumentation complex for controlling the movement of the machine and equipment of the functional module, and a niche 24 formed in the lower part. The niche mainly serves to provide the ability to place the legs of the crew members in a sitting position in accordance with ergonomic requirements.

At hatches 25-27, which serve as a crew landing and are made on the roof 19 of the superstructure, a set of observation devices 28-30 is located.

The upper part of the sides 31, 32 of the housing 1, located behind the control module 11 and connected with it, is each made in the form of a box-shaped frame 33 placed above the caterpillar, while the bottom part “d” of the frame (shown in Fig. 7) performs the function of a fender shelves. The internal volume of the frame 33 is divided by transverse partitions 34 with the formation of the compartments "e", "g", which serve to accommodate batteries, spare parts and tools of a military tracked vehicle.

On the hatch 27 mounted anti-aircraft machine gun installation 35 closed type, made with the provision of remote control firing from the control department.

To improve visibility, the driver of the VGM in the frontal sheet 16 has a window 36 (shown in Fig. 10) with a glass providing bulletproof protection for the crew.

The crew seats located at the sides of the superstructure are shifted forward relative to the centrally located seat, which allows for approximately equal ergonomic conditions for the crew.

It should be noted that the aforementioned instrument complex for controlling the movement of the machine and the equipment of the functional module can vary widely depending on the purpose of the VGM and, therefore, is not considered in the materials of this application.

From the explanatory drawings (see also Figs. 4 and 5) and examples of the implementation of the object of armored vehicles (the previously mentioned self-propelled howitzer type "Msta-S") using the proposed first and second variants of the low-chassis (Fig. 8, 9), the difference between the versions is visible . So, if in the chassis according to the first embodiment, the motor-transmission compartment 4 is located directly behind the control compartment, then the motor-transmission compartment 37 according to the second embodiment is located in the aft part of the VGM. In this regard, in the second embodiment, a lower arrangement of the crew seats is possible, which in this embodiment is limited to a lesser extent due to the lack of sufficiently large side transmission transmissions in the area behind the control module. At the same time, the diametrical dimensions of the brackets 38 of the running wheels 39 'of the chassis and the level of the common axis of the brackets 38 become a limiting factor in the height of the crew seats installed on the horizontal step "b" "of the partition 21'.

When using the chassis in both versions, a low and closer to the center of mass (in longitudinal dimensions) crew landing takes the crew to an area with a lower amplitude of longitudinal vibrations during the movement of the VGM, increasing comfort and eliminating a decrease in speed, especially in rough terrain, due to which increases the mobility of the hepatitis B. The low landing of the crew contributes to its placement in the area with reduced capabilities for direct-fire weapons, while at the same time, moving the crew forward outside (beyond the dimensions) of the track surface of the caterpillar mover reduces the likelihood of mine impact on the crew.

Thus, the proposed universal low-chassis chassis has a high level of mobility and protection of the crew from being struck by direct fire weapons and provides a high degree of protection against mine action.
