Description

The invention relates to a particular roof side mountable on a military vehicle carriage for at least one weapon, such as machine gun and the like, wherein the carriage comprises a fastened to the vehicle base and a lower part of a combat position in a transport position hinged upper mount with a Waffenhöhenrichtteil , over which the weapon of the drive train of a mechanical, electrical or hydraulic straightening drive with and without additional manual drive, since only the drive shaft is separated when folding, from the interior of the vehicle is höhenrichtbar.

In military vehicles with the roof side arranged carriage, the overall height of the vehicle is largely determined by this carriage. To reduce the vehicle overall height, for example, when passing tunnels or bridges or when transporting the corresponding vehicle by train, ship or aircraft, it is therefore for example in the published patent applications DE 10 2004 003 476 A1 and DE 10 2004 063 882 A1 known to make the upper carriage fold down.

A weapon system with various weapons in a gun carriage at a hatch of an armored vehicle shows the US 2007/0119296 A1 , These can be transferred together into a shooting position.

The DE 43 04 761 A1 describes a gun carriage for armored vehicles, which is arranged on a turntable for straightening in height and side of the vehicle. Here is an adapted height-variable position of the carriage by a Parallelogrammgestänge between carriage, vehicle roof and pivoting hatch.

A swing-away Schwenklafette reveals the DE 197 58 494 A1 , A pivot bearing associated with the pivot bearing is mounted on a lowering device by means of which the pivot bearing with the carriage and the weapon is lowered.

In the DE 10 2010 060 192 A1 the pivoting of a holder for receiving an attachment is effected by a linkage for the holder on the base.

In Lafettenanordnungen with hinged upper mount, however, it has proved to be problematic when used to operate the directional drive from the interior of the vehicle to the armature receiving cradle continuous mechanical drive train, as when folding the upper mount an angular and / or change in length of the Drivetrain is required.

The invention has for its object to provide a carriage of the type mentioned, in which the angle and length change of the drive train of the directional drive occurring in the Abklappvorgang the upper mount are compensated in a simple manner.

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 to separate the drive train when pivoting the upper mount. For this purpose, the drive train comprises at least one first drive train section guided through the lower part and at least one adjoining second drive train section guided along the upper carriage. In the region of the mutually facing surfaces of the lower part and upper mount a separable coupling is arranged, the first coupling half is connected to the first drive train section and the second coupling half with the second drive train section, so that in the battle position of the upper mount the two drive train sections axially form and / or are positively connected with each other. By folding the upper carriage in the transport position, the two coupling halves are so far apart that the two drive train sections are decoupled from each other.

For the separation and connection of the two drivetrain sections so no additional handles must be performed because the clutch separates the drive train sections automatically when folding the upper mount and connects when erecting the upper mount with each other.

It has proven to be advantageous if the coupling is a claw or toothed coupling, in which the two coupling halves have projections arranged on the front side, which in the engaged state of the coupling in each case engage in opposite interspaces between the projections.

Preferably, one of the two coupling halves is arranged axially displaceable on the associated drive train section and pressurized on its side facing away from the other coupling half side by a spring (compression spring, disc spring, etc.). As a result, a coupling of the two coupling halves is also achieved in a simple manner when initially the projections when erecting the upper mount are pressed against each other frontally. For as soon as a rotation of the first drive train section takes place, the projections of the associated coupling half reach into the interstices of adjacent projections of the opposite coupling half and are pressed by the spring in these spaces.

The coupling should advantageously be designed such that it is a compensating coupling that compensates misalignment of the two drivetrain sections. For this purpose, the coupling may contain a torsion-resistant, but also flexible part, which can compensate for the misalignment of the upper to lower axis.

Compensating the misalignment eliminates the need for elaborate adjustments, and the necessary alignment of the two drivetrain sections can be maintained despite generous manufacturing tolerances by the corresponding machining of the components, which results in a considerable cost advantage in the manufacture and assembly of the carriage.

In the Fig. 1 and 2 1 with a roof side on a not shown, in particular military vehicle can be arranged mountable carriage for a machine gun 2. The carriage 1 comprises a lower part 3 attachable to the vehicle and a lower part 3 from a combat position (FIG. Fig. 1 ) in a transport position ( Fig. 2 ) arranged about a pivot axis 4 foldable upper mount. 5

The upper carriage 5 consists of two mutually parallel cheeks 5 ', 5 ", wherein the first, front cheek 5' facing the viewer and the second, rear cheek 5" behind the image plane and in the Fig. 3 and 4 is shown in sections (for the construction of the upper mount 5 see also the above-mentioned publications DE 10 2004 003 476 A1 and DE 10 2004 063 882 A1 ).

The upper carriage 5 is connected to a weapon height directing part (cradle) 6, by means of which the weapon 2 is höhenrichtbar from a direction indicated by a dash-dotted line drive train 7 a mechanical, electrical and / or hydraulic straightening 8 from the interior of the vehicle. This drive train 7 extends between the two cheeks 5 'and 5 "of the upper carriage 5 or, as is also possible here, in the left cheek 5', 29 denotes a gear, 30 a drive pinion and 31 a toothed segment of the cradle 6.

Like that Fig. 3 and 4 can be removed, the drive train 7 consists of two drive train sections 9 and 10. In this case, the first drive train section 9 comprises a through hole 11 in which a first shaft 13 is rotatably mounted in a first bearing 12. The first drive train section 9 extends through the lower part 3 of the mount 1 into the interior of the vehicle. At the end of the first shaft 13, for example, a handwheel for manual actuation of the first shaft may be provided (not shown).

The second drive train section 10 comprises a bore 14 located in the front side cheek 5 'and a clearance in which a second shaft 16 is rotatably mounted in a second bearing 15. The second shaft 16 acts on the cradle 6 (not shown) ( Fig. 1 ).

In the region of the mutually facing surfaces 17, 18 (FIG. Fig. 1 and 2 ) of lower part 3 and upper carriage 5, the two mutually facing ends 19, 20 ( Fig. 4 ) of the first and second shafts 13 and 16 of the two drive train sections 9 and 10 can be connected to one another via a separable coupling 21.

The coupling 21 comprises a first coupling half 23 which is acted upon by a spring 22 and which is non-rotatably but axially displaceably arranged on the first shaft 13 of the first drive train section 9, and a second coupling half 24 which is rigidly connected to the second shaft 16 of the second drive train section 10 is. Both coupling halves 23, 24 have on their opposite end faces 25, 26 projections 27, 28 which engage in the engaged state of the clutch 21 (combat position of the upper mount 5) respectively in opposite spaces between the projections 27, 28 and the two shafts 13 and 16 positively connect with each other ( Fig. 3 ).

If the upper carriage 5 is brought into its folded position ( Fig. 4 ), the two coupling halves 23, 24 are so far apart that their projections 27, 28 are disengaged and thus the two drive train sections 9, 10 are completely decoupled from each other.

If the upper carriage 5 is erected again and the projections 27, 28 of the two coupling halves 23, 24 not frontally interlock, but support each other at the end, is ensured by the spring 22 that upon rotation of the first shaft 13, the projections 27 of the first coupling half 23rd be pressed into the interstices of adjacent projections 28 of the second coupling half 24.
