Description

The invention relates to the field of military equipment, in particular to methods for increasing the mobility of combat vehicles (BM) when forcing water barriers.

A known method of increasing the speed of movement of BM on the water, which consists in the fact that for the movement of the machine afloat using the forward movement of the tracks. Traction occurs when the tracks are running. The lower branches create a stream of water, using a guide element directed in the direction opposite to the movement. To reduce the resistance to movement created by the flow of water from the upper branch of the caterpillar, and increase the speed of the machine, the upper branch is closed with special wings. Turning on the water is carried out due to the difference in the speeds of rotation of the tracks (see. Technical description and instruction manual. Infantry fighting vehicle (BMP-2). Military Publishing House of the Ministry of Defense of the Russian Federation 2001 (part two). Second Edition, p. 97, 240 Open Edition Prototype).

The known method of increasing the speed of movement of BM on the water allows the movement of BM on the water, provided that it moves in 2-3 gears and a raised water-reflecting shield. However, this method has significant disadvantages. Low speed, lack of maneuverability, and difficulty in approaching an unprepared shore increase the likelihood of damage to both the machine and its crew under enemy fire.

The objective of the present invention is to increase the speed of movement and maneuverability afloat, facilitate access to unprepared shore and reduce the likelihood of enemy fire fighting a combat vehicle.

The technical result of the invention is to increase the mobility afloat BM when forcing (overcoming) water barriers, increasing its maneuverability on water, facilitating access to the unprepared shore, reducing the likelihood of damage to the machine and crew by enemy fire.

The technical solution of the proposed invention is the use of additionally installed on the chassis of the machine device. The device is a gearbox with propeller blades, fixed in such a way that when the machine is moving, the torque from the rotation of the driven wheel is transmitted by a belt drive to a step-up gearbox installed directly above the guide wheel of the chassis of the machine and through the clutch to the propeller blades. Two such devices, one on each side of the machine, create additional traction when moving on water.

A way to increase the speed of BM movement on water is based on the fact that before the machine overcomes a water barrier on the chassis, namely over the driven wheels, additionally, symmetrically from the right and left sides, devices are mounted that are fastened with fasteners to the machine’s body, which are gearboxes with rowing blades. In this case, the rotation of the driven wheels during the movement of the machine on the water drives the propeller blades through the belt drive and clutch, the rotation of the latter provides the creation of additional traction on the water and an increase in the speed of the machine afloat.

A method of increasing the speed of a combat vehicle on water, characterized in that it additionally uses torque from the driven wheel of the machine, which is transmitted through a flywheel with a shaft by means of a belt drive to the gearwheel of the gearbox, through the clutch, then through a booster gearbox and gearbox shaft to the propeller blades, which create additional traction, increase the speed of the car on the water.

The invention is illustrated in FIG. 1, which shows a method of increasing the speed of a combat vehicle on water, where 1 is a vehicle; 2 - mount; 3 - belt drive; 4 - step-up gear; 5 - rowing blades; 6 - water; 7 - a flywheel with a shaft; 8 - driven wheel; 9 - gear shaft; 10 - a flywheel of a reducer; 11 - coupling; 12 - body control water-reflective shield; 13 - electric wires.

shows the direction of rotation of the propeller blades. To increase the speed of the machine 1 through water 6, when overcoming a water barrier, an additional device is used, the essence of which is as follows.

Increasing gears 4 are additionally attached to the machine 1 by means of fastenings 2 along its right and left sides. The step-up gears 4 have gear shafts 9 on which the propeller blades are fixedly fixed 5. Flywheels with shafts 7 are connected to the driven wheels 2 of the chassis of the machine 1, which in turn, by means of a belt drive 3 and a flywheel of a reducer 10, they are connected to a booster gear 4, through a clutch 11 and with propeller blades 5. The booster gear 4 is designed to increase the amount of torque transmitted from the driven wheel 8 to child blades 5, which during rotation create additional traction, increasing the speed of the machine 1 on the water 6. Clutch 11 is designed to turn on and off the boost gear 4 by supplying a signal to it via electrical wires 13 from the control element of the water deflector 12 when the machine 1 enters the water 6 .

An example of the method

When the machine 1 enters the water 6, the driver, by means of the control element of the water deflector 12, raises the water deflector. In this case, the signal is transmitted via electric wires 13 to the clutch 11, which connects the step-up gearbox 4 and the flywheel of the gearbox 10. When the machine 1 moves through water 6, the torque from the flywheel with the shaft 7, which is fixedly attached to the driven wheel 8, is transmitted by belt drive during its rotation 3 to the flywheel of the gearbox 10, then through the clutch to the booster gearbox 4, the gearbox shaft 9, to the propeller blades 5. The rotation of the propeller blades 5 creates additional traction. In this case, the reduction gear 4 is attached to the body of the machine 1 by means of a fastener 2.

The proposed method allows to increase the mobility of a combat vehicle when moving on water, without adversely affecting the patency of the vehicle on land, and to reduce the overall probability of being hit by enemy fire (increasing security) by improving maneuverability afloat.
