DE2066170A1 - Armoured vehicle with gun - has constant-speed electric motors with electrically-controlled clutches for elevating and transversing - Google Patents

Abstract

The vehicle has one or more guns elevated and traversed by electric motors which run at constant speed and in one direction. The motors have electrically-controlled clutches, by which the gun is moved in either direction by the same motor. The elevation and traversing drives can each comprise two motors running in opposite directions, each working via an electrically-controlled clutch and gearbox. The clutches can be controlled by signals from the fire-control system. The observation system incorporates laser range finders and heat-detecting cameras apart from day and night sights.

Description

Armored vehicle

The invention relates to an armored vehicle with at least one gun, which is directed by electric motors in height and side.

They were especially for anti-tank guns - apart from manual ones Crank actuation - known electrical or hydraulic weapon straightening systems acting via gear transmission or via a hydraulic cylinder. With electrical Gun straightening systems were z. B. two electric motors are provided, one of which is the height adjustment and the other of the side adjustment the gun was assigned, d. H. the shafts of the electric motors were connected to the gun via a reduction gear. For the direction of the side z. B. a turntable with internal teeth, in which a corresponding pinion of the electric motor engaged.

When the gun is aimed at a moving target, follow each other Pivoting in height and side in different pivoting directions. When reversing the electric motor acts due to the inertia the torque first in the direction opposite to the new pivoting direction until the motor reaches its rated speed in the opposite direction has reached. This results in time delays in the straightening process, which affect the accuracy of the hit. Farther . (

there are considerable mechanical loads in the connecting elements. The time delay has a significantly more critical effect when a stationary target is shot at by an armored vehicle that is in Eahrt is, since the gun is constantly readjusted according to the uneven terrain must become. The same applies, of course, in the event that a moving target is bombarded by an armored vehicle in motion the end.

Furthermore, armored vehicles were used as single and combination devices both active infrared target devices and passive night vision devices are known. The range finders worked as optical devices in the visible range.

The invention is based on the object, on the one hand, of the straightening drive to improve for the gun, whereby the message is accelerated and thus the accuracy is increased. On the other hand, the target process should can be significantly improved, so that with the new straightening drive in particular the hit rate can be significantly improved via a fire control system. In addition, the possibility of observation, i. H. the Finding camouflaged objects during the day and at night will be improved.

The solution to the stated problem results from the features of the main claim. The subclaims relate to preferred embodiments of the straightening drive. The sub-claim 5 relates to the improvement of the distance measurement and observation.

In the armored vehicle according to the invention, an observation, Target and combat activity also while driving, at night and in bad weather possible without restrictions.

According to the preferred embodiment, the directional drives exist for the main weapon in side and height of two motors each, which run in pairs in the opposite direction of rotation at constant speed and which each have one Electrically controllable clutch via one gear each for lateral and vertical movements the main weapon effect. In known vehicles, there is only a single motor for straightening in height and for straightening after Page present. Accordingly, if the direction of direction changes, the motor must be reversed. As a result of the inertia of the revolving Masses inevitably result in delays. The consequence of this is that the weapon does not reach the target position when the vehicle is driven off-road. or not when bombarded with moving objects

can follow quickly enough. According to the stated preferred embodiment The moments of inertia of the motors running continuously in one direction of rotation now support the rapid alignment of the weapon and hinder it not as in the known embodiments.

The couplings of the straightening drives can be used both for straightening and for spatial or targeted stabilization of signals from the fire control system being controlled. The control of the main weapon can take place by means of signals from the fire control computer in such a way that even while driving the ballistically correct pipe direction in terms of bank and elevation lead angles or follow-up angle is guaranteed. The secondary weapon can also while driving through tracking systems in a similar way as the main weapon can be used fully stabilized. Through suitable tracking systems and Operating mode selection can ensure that target devices perform the task of another target device, e.g. B. in case of failure, can take over. By Suitable tracking systems and operating mode selection can also be ensured that at least two crew members are among each other Be able to fully perform observation and targeting tasks.

In summary, the following advantages can be stated. By the new straightening system is achieved:

extreme decoupling of the weapon from the carrier vehicle; thus minimal transmission of disturbances when driving off-road;

smaller overall volume due to the utilization of masses in the straightening motor, which can therefore be designed to be smaller;

Better control behavior because the directional motor starts up and brakes omitted.
