Abstract

The invention relates to an armored vehicle with a body (7), which is connected to a armored steel frame (1) enclosing an armored glass pane (5) at the edge. In order for the armor steel frame (1) of such a vehicle to be lighter in weight than known armor steel frame (1), the invention proposes to armor the steel frame (1) in whole or in part with a ballistic bullet-resistant layer (FIG. 8-8 '') of aramid, a glass fiber or a PE fiber to sheath. By such a measure it is achieved that the armor steel frame (1) may have a smaller wall thickness than known frames, because a part of the energy transmitted by the ballistic projectiles is taken up by the relatively light layer (8-8 '').

Description

The invention relates to an armored vehicle with a body, which is connected to an armored steel frame enclosing a bulletproof glass armor frame.

In vehicles in which the front, rear and / or side windows are made of bulletproof glass, the frame receiving the bulletproof glass pane serves both for mechanical fastening and as edge protection of the bulletproof glass pane. On the other hand, the frame should also provide protection against ballistic missiles, since the armor plates sandwiched together from several dividing discs are relatively sensitive at the edge. The transition armored glass pan is also a ballistic vulnerability. The frame for the bulletproof glass is therefore usually made of steel armor or aluminum in the required wall thickness for protection. This results in the case of the use of armor steel to a relatively high weight and in the case of the use of armored aluminum to very voluminous frame.

The invention has for its object to provide an armored vehicle of the type mentioned, in which the armor steel frame may have a lower weight, as this is the case with known armor steel frame.

This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.

The invention is based essentially on the idea that the armor steel frame wholly or partially with a from a ballistic bullets penetration resistant layer (hereinafter also referred to as liner active layer), for example, aramid, a glass fiber or a PE fiber (PE: polyethylene) to coat. In question are all known as ballistic liners materials, usually fiber composites. By such a measure it is achieved that the armored steel frame may have a smaller wall thickness than known frames, because a part of the energy transmitted by the ballistic projectiles is absorbed by the relatively light liner active layer.

As the Applicant's experiments have shown, in the case of a liner-effect layer adhered only to the back of the armored steel frame, when the frame is bombarded, the liner-effect layer may come off. However, this can be avoided that the armor steel frame is either completely covered with the liner-active layer or that in a partial sheathing, the ends of the liner-active layer are additionally secured.

In a tank steel frame with Z-shaped cross-section, in which the steel frame is covered with respect to the armored glass only substantially on the outside with the liner-active layer, such additional securing the liner-active layer can be effected by the first end of the liner-active layer engages behind the bulletproof glass horizontal web portion behind, while the second end of the liner-active layer is non-positively connected to the second horizontal web portion of the armored steel frame. So this solution goes a different way than that in DE 102 31 607 A1 featured armor element.

In a further embodiment of the invention, it is provided that the liner active layer, which is fastened only to the outside of the armor steel frame, is secured by an additional cover layer.

Further details and advantages of the invention will become apparent from the following, with reference to figures explained embodiments. Show it:

1 the section through a schematically illustrated attachment portion of a bulletproof glass pane with a tank steel frame, in which a liner-active layer completely sheathed the armored steel frame;

2 a 1 corresponding figure, in which a liner-active layer the armor steel frame only partially shrouded and

3 a 1 corresponding figure, in which a liner-active layer the armor steel frame is partially encased and secured by an additional cover layer.

In 1 is with 1 a Panzerstahlrahmen referred to, which has a substantially Z-shaped cross-section, wherein a first horizontal web portion 2 and a second horizontal bridge part 3 through a vertical web part 4 connected to each other. At the armored steel frame 1 is a bulletproof glass 5 by means of a corresponding potting compound 6 fixed so that the vertical web part 4 whose length is about the wall thickness of the bulletproof glass pane 5 corresponds, and the first horizontal web part 2 on the bulletproof glass 5 issue. With the second horizontal web part 3 the armor steel frame 1 is the body 7 connected to the vehicle, not shown.

As 1 is directly removable, is the armor steel frame 1 Completely with a ballistic bullets penetration resistant position 8th . for example, aramid, a glass fiber or a PE fiber sheathed.

In the in 2 illustrated embodiment is in turn with 1 designated armor steel frame in relation to the bulletproof glass pane 5 essentially only on the outside with a passage-inhibiting position for ballistic projectiles 8th' jacketed. To a detachment of the situation 8th' when a ballistic missile strikes the armor steel frame 1 to prevent it, takes hold of the first end 9 the situation 8th' that the vertical web part 4 opposite end of the first horizontal web part 2 , The second end 10 the situation 8th' is with the second horizontal web part 3 positively connected.

At another, in 3 illustrated embodiment of the armored steel frame 1 in terms of bulletproof glass 5 only on the outside with a passage-inhibiting position for ballistic projectiles 8th'' jacketed. In this case, a peel off with 8th'' designated position when hitting a ballistic projectile on the armored steel frame 1 to prevent is a topcoat 11 provided, whose first end 12 that the vertical web part 4 opposite end of the first horizontal web part 2 engages behind. The second end 13 the topcoat 11 is with the second horizontal web part 3 positively connected.
