Automatic loader tank gun
The invention relates to the field of armored vehicles, and specifically to devices providing automatic loading of the tank. The invention consists in that in the automatic loader increased pipe diameter tape and installed additional latch with the grooves on the locking end, i.e., the cassette is unified for all types of shots used in the tank, including a guided missile with an increased diameter and length. Rails with the slots of the lifting mechanism of the tapes are in the middle part of the curve, providing the necessary inclination of the cassette with a shot extended length (guided missile) to pass it from the conveyor to the line of feeding. The use of electronic storage device with position sensor cassettes, the shaft of which rotates synchronously with the rotating conveyor, allowed to increase the number of recording the types of shots loaded in the cassette, to improve the reliability of the control circuit of the automatic loader, and also reduce the weight of the electrical equipment. Installed on the remote boot ciproindication allowed to provide a visual indication of the number of cassettes with the selected type of shot (including guided missile). Offer to work automatic loader. 1 C.p. f-crystals, 5 Il. Automatic loader tank guns relates to the field of armored vehicles, and more particularly, to devices for automatic gun loading, and can be used to create automatic mechanisms other artillery systems.Known automatic loader is designed for loading the tank (see tank "URAL" and IE, kN.1, Voenizdat, Moscow, 1975, PP 105-153) artillery shots of all types with an Electromechanical device memory type shot, arranged in the cartridge when loading the rotating conveyor.Known automatic loader contains the following nodes, equipped with Electromechanical actuators: - rotating conveyor (W) tape; a lifting mechanism cassettes (IPC); - dosimeter.The electrical equipment consists of a control unit, remote boot, remote control electrically connected by wires.On the drive gear W installed Electromechanical storage device, an output gear which is engaged with the gear of the output shaft of the gearbox.All actuators are electrically connected with the control unit of the automatic loader.In the process sootvetstvuushuu type loaded shot button moving the slider to the lamella-type memory cassette with this type of shot. All types of artillery rounds are recorded in the cassette corresponding latches.The disadvantage of this design is the Electromechanical memory device having considerable dimensions, mass, friction of mechanical parts (floaters, pick-tracks, etc) with a limited number of types of shots (on the tank "URAL" - 3 type).During multiple loading different types of shots per cartridge latching type shot floaters and collector tracks are worn, soiled with wear, which leads to failure of the automatic loader. In addition, the Electromechanical memory device has an external electrical connection to the control unit fourteen wires. Pipe diameter tape, and put the shells, it is not possible to place the shells with a larger diameter, and a lifting mechanism tapes do not allow passage of cassettes with the shell increased length of W to the line of feeding.In the process of modernization of the tank there is a necessity to use new types of shots, for example, guided missile and, as a consequence, introduction to memorize/p> Used in tank shells increased length and large diameter (for example, guided missile) requires: - locating and fixing (for example, new types of missiles guided missile) in the cassette; - changing the window issue in the flooring W due to the increased length of the shells relative to the lengths of the shells used in the tank; - profiling (i.e., bending) of the guide mechanism of lifting tapes to ensure the passage of cassettes loaded with all types used in the tank shots (including missiles) from rotating conveyor on the line of feeding.The aim of the present invention is to increase the power of the tank due to: - use in the tank of new types of shots (e.g., guided missile) is placed and fixed in the cassette W automatic loader; - the use of electronic storage devices.The novelty of the proposed automatic loader is that: - increased pipe diameter tape, and put the shells and rocket, i.e., the cassette is unified for all types of shots used in the tank;
- in cartridges installed the additional latch for fixing the guided missile. At the end of the latch, on both sides, the grooves, excluding spontaneous refix is djema cassettes, ensuring the passage of a cassette loaded with a shot extended length (e.g., missile) from rotating conveyor on the line of feeding;
- applied electronic storage device, a sensor which, together with the actuator placed on the gear drive rotating conveyor. Actuator sensor provides simultaneous shaft rotation sensor and a rotating conveyor. The sensor is connected to the control unit three wire, instead of the fourteen wires, which were connected Electromechanical storage device control unit, which increases the reliability of the automatic loader. As the sensor uses a rotating transformer.The invention is illustrated by drawings, where Fig.1 shows the automatic loader of Fig.2 shows a cartridge with a larger diameter and a latch with grooves on two sides for guided missile of Fig.3 shows the lifting mechanism of the cassette with the guides, made with a bend in the middle part, which provides the desired trajectory of the cartridge with a shot of Fig. 4 shows a gear with a rotating transformer (position sensor cassettes) and its drive system of Fig.5 (parts 1 and 2) shows the connection diagram of the electronic what LTE download.Automatic loader includes rotating the conveyor 2, the cartridge 3 with the latch 4, the lifting mechanism of the cassette 5, desilter 6, rotating the conveyor 7, the electrical equipment (see Fig.5 - parts 1 and 2).The operation of the automatic loader

SUBSTANCE: invention relates to armored vehicles, namely, to the tank gun loading automatic devices mounted in the behind-the-turret carry-and-load conveyors of modern tanks, and can be used in development of new tank designs or their updating. The conveyor housing accommodates an endless conveyor of two-flap cartridges receiving gun rounds and furnished with a chain drive, conveyor stop and round ramming mechanisms. The cartridge flaps effect relative vertical motion on turning about horizontal pivot. The lower flap features a chute-like shape, while the upper one has the shape that serves to prevent lengthwise moves of the round. The lower flap is provided with a roll for the former to be locked closed in the conveyor. The conveyor housing front part accommodates a crosswise frame with its inner outline equidistant to cartridge trajectory during conveyor rotation. The frame lower part has a slot furnished with a movable plate designed to break the racetrack loop and to release the lower flap. Lower flap is pressed against the upper one prevent lengthwise moves of the round.
EFFECT: improved protection of rounds, increased stability of loading in tank motion, simplified design and smaller sizes.
