Abstract

An armoured vehicle (2, Fig 1) comprises a blast resistant floor panel 4 which is profiled along it's peripheral edges 4E so as to overlap with the armoured wall panels 5 and/or the wheel arch panels 11 and wherein the overlapping joint is welded along both edges (as shown by weld points 13, 14). Furthermore, wheel arch panels 11 comprise a plurality of apertures 12 on the underside which accommodates tabs 10T and therefore forms an interlocking joint between an associated side panel 10 and arch panel 11. Elements 13, 14, 10W and 10S identify welded joints. Both floor panel 4 and wheel arch panel 11 may be made from 3mm thick, high strength steel plating. The arrangement aims to provide an increased resistance to failure about the joints when an explosion from underneath the floor panel 4 is experienced.

Description

25o 7S ( - 1 An Armoured Vehicle This invention relates to armoured
vehicles and in particular to an improved body structure for such vehicles.
It is known to provide an armoured vehicle with a body structure including panels made from armour plate to resist the effect of attack by small arms fire and small 5 explosive devices such as land mines. The known armoured vehicles commonly utilise a body construction in which a number of separate panels are joined together along their peripheral margins by continuous butt welds. These suffer from the disadvantage that the strength of the body structure is determined to a large extent by the integrity of the welds holding the body structure together.
10 It is an object of this invention to provide an armoured vehicle having an improved body structure.
According to the invention there is provided an armoured vehicle having a body structure comprising left and right side structures made from armour plate and a floor panel made from a blast resistant material, wherein the outer side margin of the floor 15 panel forms an overlapping joint with an adjacent margin of a respective part of the side structure to which it is attached such that the floor panel lies to the outside of the vehicle at the overlapping joint and the overlapping joint is welded along both edges.
The part of the side structure may be one of or both of a side panel of the armoured vehicle and a one piece wheel arch panel.
20 In a preferred arrangement the floor panel is bent upwards along its peripheral margins to overlie the respective part of the side structure to which it is attached.
Alternatively, the respective part of the side structure to which the floor panel is attached is bent inwards along its overlying peripheral margin.
- 2 - The wheel arch panel may be attached along an opposite margin to a side panel of the armoured vehicle, in which case the wheel arch panel may have a number of apertures for accommodating tabs formed along the margin of the respective side panel to form an interlocking joint therebetween. Preferably, each side panel is welded 5 on both sides to the respective wheel arch panel to which it is attached.
The body structure may further comprise a rear wall, the floor panel being bent upwards to overlie an adjacent margin of the rear wall at an overlapping joint such that the floor panel lies to the outside of the vehicle at the overlapping joint and the overlapping joint is welded along both edges. Alternatively, the rear wall may be bent 10 inwards to overlie the adjacent margin of the floor panel at an overlapping joint such that the floor panel lies to the outside of the vehicle at the overlapping joint and the overlapping joint is welded along both edges.
The body structure may further comprise a front wall, the floor panel being bent upwards to overlie an adjacent margin of the front wall at an overlapping joint such that 15 the floor panel lies to the outside of the vehicle at the overlapping joint and the overlapping joint is welded along both edges. Alternatively, the front wall may be bent inwards to overlie an adjacent margin of the floor panel at an overlapping joint such that the floor panel lies to the outside of the vehicle at the overlapping joint and the overlapping joint is welded along both edges.
20 One or both of the floor panel and the wheel arch panel may be made from a high strength metallic material such as high strength steel, e.g. 3mm thick.
The invention will now be described by way of example and with reference to the accompanying drawings, of which: Fig.1 is a side view of an armoured vehicle according to the invention; 25 Fig.2 is cross-section along the line Y-Y on Fig.1;
-3 Fig. 3 is a cross-section along the line X-X on Fig.1; and Fig.4 is view similar to Fig. 3 showing a modification.
An armoured vehicle 2 has a rear wheel 7 rotatably mounted within a rear wheel arch 6, a front wheel 8 rotatably mounted within a front wheel arch 9 and a body 5 structure comprising left and right side structures 5. Only the left hand side structure 5 is shown and this will be described in detail, a similar body construction being used on the right hand side of the armoured vehicle 2. The side structures 5 are made from armour plate and are joined together along their lower margins by a floor panel 4 made from a blast resistant material, the floor panel 4 being bent upwards along its side 10 peripheral margins to overlie an adjacent margin of a respective part of the side structure 5.
The part of the side structure 5 to which the floor panel 4 is attached will depend upon its position along the armoured vehicle. Fig.2 shows the arrangement indicated at the position indicated by the line Y-Y. At this location the floor panel 4 has a 15 peripheral margin bent upwards to overlie a side panel 10, to form an overlapping joint, the floor panel 4 having an exterior weld 10E and an interior weld 10B to attach it to the side panel 10 so that the floor panel is welded along both margins of the overlapping joint. The exterior weld 10E is a continuous weld to produce a water resistant joint while the interior weld 10B can be either a continuous weld or a stitch 20 weld, i.e. made up of several short lengths of weld spaced out along the length of the side wall panel 10.
The side panel 10 is made from 4mm thick steel armour plate and the floor panel is made from 3mm thick high strength steel plate such as Weldox (Trade Mark).
However, the side wall and floor panels may be made from other metallic materials 25 such as hardened or high strength aluminium alloy.
Fig.3 shows the situation in the region of a rear wheel arch 6 as indicated by the line X-X on Fig.1. In this case the floor panel 4 is not connected directly to the side wall panel 10 but is connected to a one piece wheel arch panel 11 which defines the interior shape of the rear wheel arch 6. The wheel arch panel 11 is located inside of the floor panel 4 and is attached to the floor panel by welds 13, 14. Again, the peripheral margin of the floor panel 4 is bent upwards to overlie the wheel arch panel 11 to form an overlapping joint, the exterior weld 13 being a continuous weld to produce a water resistant joint while the interior weld 14 is either a continuous weld or a stitch weld.
10The wheel arch panel 11 has a number of apertures 12 adjacent the outer margin 9 which accommodate tabs 10T on the lower margin of the respective side panel 10 to form an interlocking joint. To hold the components together the side panel 10 is welded on both sides to the respective wheel arch panel 11 to which it is attached. An outer side of the side panel 10 is attached to the wheel arch panel 11 by a continuous 15weld 10W and an inner side of the side panel 10 is attached by a welded joint 10S which may be a continuous weld or may be a stitch weld.
The armoured vehicle also has a front wall and a rear wall which in combination with a roof panel define an interior space in the form of a passenger compartment (not shown). The front and rear margins of the floor panel 4 are also be bent upwards to 20 overlie an adjacent margin of the rear wall and an adjacent margin of the front wall and are welded in a manner similar to that shown in Fig.2.
The thickness of the material used for the one-piece wheel arch panel 11 and the floor panel 4 will depend upon the threat to be overcome and the type of material used.
Typically, to resist a 3Kg land mine the vehicle will require side panels 10 of 4mm thick 25 armour plate while 3 mm thick high strength steel plate such as Weldox (Trade Mark) can be used for the wheel arch panel 11 and the floor panel 4.
f By arranging for the floor panel to be bent upwards to form art external overlapping joint with the side, rear or front walls of the armoured vehicle, an improved blast resistant structure is produced that is less affected by the quality or integrity of the welded joints. For example, a blast impinging upon the floor panel 4 will cause the 5 floor panel 4 to be moved upwards but, because the floor panel 4 overlaps the wheel arch panel 11, the load will be transferred to the end of the wheel arch panel 11 and will tend to compress the weld t4. In effect, the end of the wheel arch member 11 abuts against the inner surface of the floor panel 4. Similarly, However, due to the overlap joint construction, the blast will not need to be resisted in a tensile manner by 10 the welds 10E, 10B because the lower margin of the side wall panel 10 abuts directly against the inner surface of the floor panel 4. Also, the wheel arch panel 11 will be forced up against the side panel 10 and so the interlocking joint transfers the load rather than the welds 1 0W, 1 US which merely hold the two parts together. Hence any blast loads from below the floor are transferred directly into the part of the side 15 structure to which the floor is attached and do not impart a tensile load on any welded joints used to connect the various components together.
The modification shown in Fig.4 is an alternative construction to that shown in Fig.2, the side panel 10 being bent inwards at its lower margin so that the floor panel 4 again overlies the side panel 10 to form an overlapping joint, the floor panel 4 having a 20 continuous outer weld to produce a water resistant joint while the interior weld is either a continuous weld or a stitch weld. Such a joint could also be used at the interface between the floor panel and the wheel arch panel or between the floor panel and any other panel such as the front or rear walls.
The term armour plate as meant herein relates to materials having sufficient 25 hardness to resist penetration by ballistic objects such as bullets. The term blast resistant material relates to materials having sufficient strength to resist blasts.
Ordinarily, the side walls of the armoured vehicle would require the use of hard armour
- 6 plate and the floor structure would require the use of high strength material able to
