Description

81Û0242 == Û 2 If a barrel weapon is suspended in its center of gravity, which lies on the elevation pin axis, no torque occurs in the weapon balanced around the elevation pin axis, both during acceleration and during deceleration of the vehicle.

The weapon is relaxed from body movement about the rocking axis (= transverse axis) and due to its inertia in neglecting the small bearing friction craters has no tendency to move from this position. During alignment processes in height, however, acceleration forces must be introduced into the weapon. It is known to support these forces against the armored body by means of mechanical, electrical, hydraulic or other adjusting means. The object of the invention is to provide the necessary reaction moment for the alignment process without the relative movements of the vehicle body during power transmission also being taken into account in the stabilization system.

The invention is defined with respect to its technical purposes and the technical means required for the solution in the claims.

The sliding clutches are designed, for example, as mechanical disc, lamella or reversing brakes, as electric eddy current clutch, as hydrodynamic clutch or as a single-stage power-shifting planetary gear with hydrodynamic retarder, whose sun wheels rest against the rotor of a hydrodynamic retarder with body-fixed stator the mass of weapons and whose planet carrier is driven from a propulsion unit in the body.

The primary side of the above-mentioned embodiments of the couplings can also be driven by a flywheel disconnected from the body about its axis of rotation, which sits on the elevation pin shaft.

In the embodiment as a planetary gear with hydrodynamic retarder, the planet carrier is then driven from the flywheel. In the case of power transmission by means of flywheel, a mode of operation with high speed and sliding of the clutches is not required. 3 8100242-0 In this case, however, it must be ensured that the lift pin shaft is disconnected from the body and the feed motor for the flywheel is not driven during the stabilization process.

The speeds or angular velocities at which the primary sides of the sliding clutch elements are driven must be substantially higher than the angular velocities resulting from the rocking oscillations of the vehicle body. In applying this principle, the oscillating excitations which tend to be transmitted by oscillating oscillations of the body via the drive means to the balanced barrel are neglected. In a further embodiment, it is intended to use a sliding brake system, such as for example the electrically actuable eddy current clutch, as a fine adjusting means, while for the high setting torques a mechanical force-closing disc brake is used, for example. Other anti-slip sliding brake systems, such as hydrodynamic retarders and clutches, can also be used. With an in-vehicle vehicle braking system with hydrodynamic retarder, it is possible to transfer effects of more than 1000 hp, so that the necessary directional effects can be achieved without further ado.

An additional advantage exists when using stepless, for example by thyristors controllable, eddy current connections, which are precisely so controllable that constantly acting driving moments for equalizing imbalances in the weapon act. The same exact control option is also available for hydrodynamic couplings and retarders through a combined filling and pressure control.

In order to have corresponding adjusting means for both directions of rotation, these can be driven over a corresponding distributor gear by means of a drive device from the body. In order to achieve short reaction times, it is possible to couple two brake systems for left and right movement to each other and by reducing the torque of one brake resp. reinforcement of the other achieve a rapid control.

Since by means of the invention a faultless decoupling of the weapon from the body movements occurs, the highest torque and maximum effects can be transmitted to the weapon and imbalances 111%? S1ÛÛ242 = Û L 'around the elevation pin axis can be compensated by means of this system, the object of the invention is also suitable as a drive system for a weapon, which is to be controlled from a stabilized observation device. The control units for the directional adjustment means (coupling) receive the adjustment signals by a comparison (counter) of the target line with the core line of the weapon in the room. As soon as the two lines do not run in parallel, impulses are emitted to the control units of the fine-tuning means, which control the weapon, until the angular error is again regulated to zero, i.e. the target line and the barrel core line run in parallel again.

In the case of ballistic firing, however, the correction angles determined by a calculator, which are obtained, for example, from barrel elevation or barrel position, can also be taken into account.

The drive system according to the invention is not only limited to the stabilization of weapon systems on mobile vehicles. At the same time, mobile platforms of any kind can also be effectively stabilized.

The invention will be described in more detail below in connection with the accompanying drawing, which shows exemplary embodiments. 7Fig. Fig. 1 is a schematic overall view of a device according to the invention with motor drive, Fig. 2-H shows different embodiments of the couplings used in the device according to Fig. 1, Fig. 5 is a schematic overall view of a device according to the invention with flywheel drive.

Fig. 1 shows as an example of a weapon drive device the structure and function of the disconnected drive device, i.e. free from disturbing external moments. The center of gravity of the weapon 1 is on the bearing shaft, namely the elevation pin axis 2. In the invention, minor deviations between the center of gravity axis and the elevation pin axis can also be allowed. The two directional drive devices are arranged on the elevation pin shaft 2. However, this arrangement is not a necessary condition, but it complies with the room conditions that apply. 5 8100242-0 A directional drive device for upward orientation and one for downward orientation are available. Each directional drive device each has a control means 3 for coarse direction and a control means H for fine direction. The drive of the two directional drive devices takes place over a gear transmission 5,6 each, which are both driven from the main shaft 7 over a conical gear 8 with the same speed, but in opposite directions of rotation. The main shaft can be driven from an arbitrary drive motor 9, for example from a drive motor or from a flywheel energy accumulator. Due to the sliding at the four-setting means 4, speed variations are permissible within certain limits. The task of the fine-tuning means H is to keep the steered barrel core axis at target coverage, whereby internal and external ballistic correction factors can easily be taken into account. These aftershock movements can result from movement of the target or from one's own movement.

If necessary, the coarse adjusting means 3 can be rigidly coupled to the drive motor 9, each of which can be engaged and disengaged, with a force-clutching mechanical coupling.

The high effects required for this purpose for a short time can, for example, be obtained without further ado from the drive motor 9 or, for example, from a flywheel energy accumulator 9. For the technical realization of the coarse and fine adjustment means resp. the sliding couplings have different release possibilities. Fig. 2-H shows three different possibilities.

As a fine adjusting means, an electric eddy current coupling is used in Fig. 2. The clutch torque can, for example, be adjusted as required by means of a thyristor control with very short dead and setting times. Due to the horizontal torque and speed characteristics at a certain excitation in a certain speed range, rocking oscillations do not exert a disturbing influence on the weapon 1, which is to be steered.

In Fig. 3, a hydrodynamic coupling is used as the fine adjusting means. The magnitude of the VPÛOR QUÄLiIi'ïMg '8lÛÛ242 = -Û 5 torque (torque) can be adjusted by means of a combined pressure and filling control of the coupling, as required, with very small dead and setting times.

Here too, the rocking oscillations, due to the characteristics of the hydrodynamic coupling, do not exert a disturbing influence on the weapon which is to be steered.

In Fig. H, a hydrodynamic retarder is connected as a fine-tuning means in connection with a planetary gear. Even with this device, the required torque and torque control are regulated with a combined pressure and filling control with very short dead and setting times. Due to the thus adjustable characteristics of the hydrodynamic retarder, the rocking oscillations cannot affect the weapon being steered. By means of the power-branching planetary gear, a reaction-torque-free torque increase for the weapon to be steered becomes possible. The adjustment signals are received by the control units from the direction setting means, for example via an electronic counter, which processes all measuring and influencing quantities.

Fig. 5 shows an exemplary embodiment for driving with a flywheel accumulator. In this case, energy is transferred from two flywheels 10, which sit on the elevation pin shaft 2 and which are thereby relaxed around their axes of rotation from the body series to the weapon to be steered. In this device shown, a flywheel for upward direction and for downward direction is each required. Furthermore, however, devices are also possible which only require a flywheel for upward direction and downward direction. The two flywheels 10 are accelerated intermittently from the feed motor 11, whose rotor 12 is likewise disconnected from its body from its body to the axis of rotation to the operating speed. The gear transmission 13 is required in a single-engine version for driving the second flywheel in the opposite direction of rotation. The construction groups already shown in Figs. 2, 3 and R can be used as coupling elements.

As an alternative, a two-engine drive with the motor lu (dashed line) and elimination of the gear 12 is also possible. 7 - 8100242-0 By a slight counter-coupling of the two fine-tuning adjusting means (Figs. 2-5) "upwards" and "downwards" mutually, the dead and setting times can be shortened. Minor disturbances, which result from air forces or from imbalances, which arise, for example, from various ammunition failures and from the influence of foreign bodies on the weapon, can be continuously compensated according to the list by the fine-tuning means "upwards" or "downwards" without impairing the steering accuracy. mon QUALITY,
