Description

Face with superimposed azimuthal movements

The invention relates to a gun or tower for a weapon that is arranged, for example, on a roof of a vehicle's hull.

From document DE 31 08 132 A1 an articulated apron for armored vehicles is known, whose housing of the weapon is arranged centered on a block made of armored glass and moves with it. The block is in gimbal or mounted on a cross joint. In this way dead spaces are avoided and a good circular defense is achieved.

Document DE 199 27 656 A1 discloses an armored transport vehicle with a groove mounted on a rotating crown on the roof. The electrical energy needed for the remote control and the electrical signals are transmitted through a collector ring in the nick tower.

US 5,353,680 A refers to a weapon that can be mounted on a tower in an armored vehicle. This can be rotated around an axis of the tower. In addition, a rotating component is incorporated in the area of a vehicle roof opening. A hatch cover is placed in a partial area of the rotating component. In front of the hatch cover is the weapon that fits (rotates) with respect to the rotating component. The transmission of energy to the weapon itself is done by a collecting ring. The rotational movement of the component is in this case independent of the rotational movement of the hatch.

Document DE 31 22 696 A1 discloses a set according to the preamble of claim 1; It deals with a gun for machine guns or similar weapons. This is configured with two pivoted articulated arms in a deformed manner relative to each other around a perpendicular axis and offset relative to each other in height. The lower pivot arm is mounted with its free end pivotably on a fixed perpendicular journal. The upper pivot arm, configured as a vertically adjustable parallelogram frame, has at its free end a housing for rotating attachment of a bearing fork for the weapon. The shaft has a first chain wheel that is connected through chains with a second chain wheel. In this case the first pivot arm can be pivoted around a pivot pivot and the second pivot arm around a pivot pivot. Ratchets allow independent pivot of the pivot arms.

EP 0 899 533 A2 describes a pivot point on a support that is arranged in front of a tower hatch. On the upper side of the support a rotation bearing is placed on which a pivot arm with its front end is rotatably mounted. This pivot arm carries a pivot and weight compensation device at its rear end, on which a machine gun is pivotally mounted.

EP 0 878 868 A2 refers to a weapon control system with a weapon stabilization.

In the case of weapons mounted on vehicles that do not have a collector ring transmitter, the current and electrical signals are transmitted through cables to the hull. The orientation range is limited because the cable (s) wrap the spindle during the rotational movement in the horizontal plane and hinder the spindle operator. It is known, in the case of artillery pieces mounted on vehicles without a collector ring transmitter, to conduct the cables around in an energy guidance chain or in a rigid channel around the weapon operator and provide for a length compensation at an appropriate point , for example, by forming a loop, etc. The cables are therefore driven down in practice in a device that rotates with the spindle and is placed in position by means of a spiral configuration, so that the spindle can be rotated without any operator wrapping or obstruction.

It is disadvantageous that the cable (s) driven down with its support cause a large area of disturbance inside the vehicle, which makes it impossible to use this space for people and / or to store objects. The cables laid around the afloat with the necessary length compensation hinder the visibility and freedom of movement of the operator and require a lot of free space.

Document DE 197 51 305 A1 refers to a device for the height and lateral orientation of a groove that can be rotated with respect to a command post. Orientation in height is done through a kinematic chain. An intermediate ring used in this case is arranged concentrically with respect to the axis of rotation of the thread. The cavity formed in this case can serve as a passage for the actuation devices of an artillery piece and / or cables, for example, of a video camera to aim.

The invention has the objective of showing a possibility that allows the cable / wires of an aftertaste not to cut the space inside the vehicle nor to hinder the visibility or mobility of the aforementioned or the operator during the rotation in the horizontal plane.

This objective is solved according to the invention by the features of claim 1.

The dependent claims disclose other particularly advantageous configurations of the invention.

The invention is essentially based on the idea of separating the orientation movement of the aforement with the weapon and the barrel of the weapon from the orientation movement of the weapon itself, so that a movement is introduced into the azimuthal axis through the side bearing bearing (primary axis) of the shaft, however, the weapon is further rotated or returned and in this case it is oriented through its own horizontal rotation axis (secondary axis).

The weapon is necessarily controlled by a primary drive through a second lateral rotation bearing by means of a gear.

In principle, the secondary axis is located at any distance from the primary axis, therefore it can be positioned freely selectable.

The rotational movement around the primary axis is introduced through an electrically, hydraulically or manually operated unit. The weapon support rotatably mounted around the secondary axis is pivoted in this case by multiplications of multiplications. The weapon can advance or fall behind from the starting position.

By means of a similar arrangement consisting of two rotation axes spaced apart from one another and arranged in parallel with each other, it is achieved that by a multiplication / demultiplication of the primary axis with respect to the secondary axis, the orientation angle of the primary axis can be reduced and consequently the space for cables for the transmission of information and energy can also be clearly reduced.

In fig. 1 with 20 marks an appendage that has an upper aforement 3 for the support of a weapon designated with 1 (for example, an automatic cannon) with the barrel of the weapon 2, which is fixed in an adjustable way in height in the aforesaid 2. With 4, as an embodiment, a hatch cover is marked on which the upper aft 3 is fixed through a base plate 5. In the exemplary embodiment shown the hatch cover 4 is part of the aft 20.

The weapon 1 with the barrel of the weapon 2, as well as the upper shaft 3, the base plate 5 and the hatch cover 4 can be rotated around a first rotation axis (primary axis) 6 of a first lateral rotation bearing ( primary) 7. The rotational movement of these parts is carried out by a primary drive 8.

In addition, the weapon 1 with the barrel of the weapon 2, as well as the upper shaft 3 are rotatably arranged around a second vertical rotation axis (secondary axis) 9 in another lateral rotation (secondary) bearing (rotating crown bearing ) 10. The rotation movement of the weapon 1 is carried out by a secondary drive 11.

Fig. 1a shows the weapon 1 with the barrel of the weapon 2 and the upper shaft 3 in a so-called resting position. With 12 the center of rotation of the weapon 1 (secondary center of rotation) on the secondary axis 9 is designated, and with 13 the center of rotation of the shaft 3 (center of primary rotation) on the primary axis 6.

Now the other figures explain in more detail the mode of operation or possible embodiments by way of

as an example

Fig. 2 shows the weapon 1 with the barrel of the weapon 2 and the upper shaft 3 in a position rotated at an angle η around the secondary axis 9 (center of secondary rotation 12) with respect to the rest position (initial position). The hatch cover 4 has remained in its resting position.

In fig. 3 and fig. 4 combinations are now represented for a rotation of the weapon 1 with the barrel of the weapon 2 and afloat 3, the base plate 5 and the hatch cover, on the one hand, and the independent rotation of the weapon 1 with the barrel of the weapon 2 and the set 3, on the other hand.

In fig. 3 the weapon 1 with the barrel of the weapon 2, the upper shaft 3, the base plate 5, as well as the hatch cover 4 are rotated on an axis κ1 and the weapon 1 with the barrel 2 and upper shaft 3 at an angle η1 . The weapon 1 with the barrel of the weapon 2 is pivoted with respect to the rest position at a total angle λ1.

In fig. 4, the weapon 1 with the barrel of the weapon 2, the upper thruster 3, the base plate 5, as well as the hatch cover 4 are rotated at an angle κ2, the weapon 1 with the barrel 2 and upper thrust 3 same in another angle η1, so that it is the sum, the weapon 1 with the barrel of the weapon 2 has forced a change of λ2 with respect to the initial or rest position.

Weapon 1 moves forward once from the initial position (fig. 3) or can be left behind (fig. 4).

Fig. 5 shows the invention according to claim 1, a first connection with a roof of the hull 14, which differs from another one in particular by the additional drive 11.1. The lateral orientation bearing 7 is connected to a hull of the hull 15 of the hull roof 4. The second lateral orientation axis, that is, the secondary axis 9 is operated here by means of a gear 11.1. As primary drive 8 there is provided here, for example, a conventional electric drive (motor). The rotation movement is transmitted through the sprockets

11.1.1 and 11.1.2 on another cogwheel 11.1.3 of gear 11.1 for multiplication or demultiplication (switchable). This cogwheel 11.1.3 transmits, on its side, the rotational movement on the secondary lateral rotation bearing 10 of the weapon. Weapon 1 is then rotated according to multiplication / demultiplication.

The cooperation of the transmissions is represented in more detail in Figures 6 and 7. Fig. 6 shows the system in the initial or rest position, fig. 7 in a pivoted position. The electric drive 8 is located on the base plate 5 (fig. 5), whose pinion Z1 engages in the inner teeth Z2 of the outer ring of the side rotation bearing 7 rigidly connected to the hull frame 15. Consequently the weapon 1 with the barrel of the weapon 2, the upper shaft 3, the base plate 5 and the hatch cover 4 are rotated together with the drive 8 around the primary axis 6 at a first angle β. By means of the gear 11.1 (in this case composed of the sprockets 11.1.1 to 11.1.3 or Z4, Z5, Z6) the multiplication and the direction of rotation γ are modified. The weapon 1 with the barrel of the weapon 2 is then rotated together with the upper shaft 3 around the secondary axis 9 (center of secondary rotation 12) relatively relative to the roof of the hull (tower) at an angle δ. The overall system (20) has been rotated at a total angle ε from the primary axis 6.

In another embodiment not according to the invention according to Figures 8 and 9, the secondary drive 11 is an uncoupled system of the primary drive 8 (not shown in detail). A first drive 8 is also located on the base plate 5, whose pinion Z1 'engages in the teeth Z2' of the outer ring of the primary side rotation bearing 7 rigidly connected with the bowl fence 15. The gun 1 is rotated with the barrel of the weapon 2, the upper shaft 3, the base plate 5 and the hatch cover 4 together with the drive 8 around the primary axis 6 at the angle β. By means of the additional drive 11, for example an electric motor, the multiplication and direction of rotation γ can be modified through the pinion Z3 ', which meshes in the groove Z4' in the lateral rotation bearing 10 (fixedly to hull or tower). The weapon 1 with the barrel of the weapon 2 and the upper shaft 3 can be rotated by actuation 11 additionally around the secondary axis 9 relative to the vehicle at angle δ. The total system (20) has been rotated at a total angle ε of the central axis.

Referred to primary axis 6, weapon 1 is rotated in both cases at an angle ε = β + δ. In a numerical example, an angle α of the drive 8 of 64 ° would cause a change of the weapon 1 with the barrel of the weapon 2 (and upper thrust 3) of 20 ° around the primary axis 6, the forced controlled angular movement δ attached thereto of 15 ° around the secondary axis 9 would cause an angular position ε of the weapon 1 with respect to the primary axis 6 of 35 °.

It is understood that also the aforementioned 20 aforementioned or the principle linked therewith of the rotation of the weapon can also be integrated into a tower that is rotated by a primary lateral rotation bearing.
