Description

DESCRIPTION

Articulated vehicle, in particular armored vehicle

The invention relates to a articulated vehicle, preferably for transporting a crew.

To make even larger vehicles maneuverable or to give them a higher modularity, vehicles are often subdivided. is known among other armored terrain transport vehicle BV 206 of the company Hägglund (see for example http://www.deutschesheer.de/portal/a/heer/kcxml/04 Si9SPvkssv0xPLMnMz0vM0Y QizKLN zSLt3C0AMmZxbvHm7mb60eCGOYmRhAxkl_vBM0qQqiloJVXf1vM N1XfWz9AvvA3NKI_cO VERAHsLzoα! / delta / base64xml / L2dJQSEvUUt3QS80SWFLzZfMTZfOEFC? vw contentURL = % 2FC1256F870054206E% 2FW269WBR6361 INFODE% 2Fcontent.isp or http://www.qooqle.de/imgres?imqurl=http://www.panzerbaer.de/helper/pix/bw bv 206 d- 1906. jpg & imqrefurl = http: / / www panzerbaer.com/helper/bw trspfz bv206d- a.htm & h = 332 & w = 650 & sz = 115 & tbnid = X4pFmZPhzhhG6M :: & tbnh = 70 & tbnw = 137 & prev = / ima tot% 3Fq% 3Dh% 25C3% 25A4qqlund & hl = en & usq = 6XYI7d4oCi8iQKnFcYzFQ8fylY = & ei = 8r6a SfLtNsam-qaf4LizCA & sa = X & oi = imaqe result & resnum = 4 & ct = image & cd = 1). Here, a rear vehicle or vehicle part of the same height is pulled by the front vehicle. In the front vehicle with drive are next to the driver and passenger other people to be transported. People can also be carried in the rear part of the vehicle.

The invention has as its object to provide a new concept for such preferably armored vehicles, which ensures sufficient maneuverability.

The problem is solved by the features of claim 1, wherein advantageous embodiments are listed in the dependent claims. The invention is based on the idea of subdividing a vehicle into a front drive module and a rear mission module, both of which are connected to one another by an articulated steering or articulated link drive such that the front module is guided by the rear module accommodating at least one driver wherein the front module drives and moves the rear by means of the articulated steering drive.

Although DE 10 2004 026 237 A1 discloses the tendency to provide the drives of the vehicle in a front and / or rear module separate from a main module. However, this is done to increase the vehicle protection against the action of a landmine. The steering is conventional.

From DE 101 00 775 A1 a articulated vehicle is known, which contains two chassis parts arranged one behind the other in the vehicle longitudinal direction, on which on the one hand a front axle and on the other hand a rear axle are fastened. Both chassis parts are connected to each other via a substantially vertically aligned bending axis in such a way that they can be pivoted using a control device against each other and thus allow a vehicle steering.

With the AT-PS 332 231 a vehicle with articulated steering is disclosed, in which the front and the rear chassis part are connected to each other via a double articulated joint. In the steering linkage between the double articulated joint and the front chassis part on the one hand and the rear chassis part on the other hand, a hydraulically actuated lifting unit, etc. is arranged in each case.

A steering control linkage for articulated vehicles is described in DD 219 003 A3. In order to achieve an improved steering behavior, it is proposed that the steering column be displaceably arranged on a vehicle part, so that a steering deflection thus causes the actuation of the positioning motors for mutual buckling of the vehicle parts.

A articulated vehicle, in particular wheel loader, is also known from DE 20 2006 015 828 U1. Here, a front end and a rear end are connected to each other via a fixedly arranged spherical bearing. Guiding an unmanned vehicle from a behind it, constructively decoupled vehicle by means of an electronic drawbar describes the DE 10 2004 003 055 A1.

Otherwise, as already mentioned, the present solution. This binds between a self-contained drive module that contains only the drive, and a mission module, for example, only the crew with it, a Knicklenkerantrieb, the steering of the (unmanned) front drive module from the (manned) rear mission module on the Articulated steering or the articulated steering drive. The drive module in turn drives both the drive module and the articulated steering drive to the mission module. To supply the mission module with power, lines from the drive module can be transferred to the mission module. Alternatively, an own power supply in the mission module (also in addition) be installed, z. B. via a PTO of the articulated steering drive driven gear elements. The articulated link drive thus connects both vehicle modules to a vehicle unit.

A consequent advantage is that only the mission module needs to have a high level of protection, i.e., would need to be fully armored. This, the vehicle crew (driver, passenger / commander) leading module itself has a low IR signature, as this has no engine.

Another advantage is the possible low construction of the drive module, since there are no people to be carried along, and only the drive unit and the associated drive elements must be accommodated. In addition, the drive module only needs to be equipped with, for example, heat-insulating agents against its own IR signature instead of the armor necessary for people. Due to the fact that the drive module only has to carry the drive, but no longer a part of the crew, the modularity of the drive is also increased for other mission modules (eg as a drive for a corresponding sanitary module). In addition to the greater flexibility and availability due to the easily replaceable mission modules, the unmanned drive module can also serve as a mine trigger, as the rear module follows the front true to the track. As a result, all types of anti-tank mines known today are triggered by the unmanned propulsion module, and the mission module carrying the crew is thus completely protected against mine threats of any kind. In modern tracked vehicles steering takes place by means of a hydrostatic superposition gearbox, which assigns a different drive speed to the right and the left chain, and thus enables a steering movement. The disadvantage of such a design is that a large part of the drive power is consumed by the hydrostatic superposition gear and is not available for propulsion. In the embodiment presented here, the steering movement takes place by the bending of the drive module from the mission module by means of the articulated steering drive, and not by a different speed of the right and left drive side. As a result, the full engine power is available for driving even when cornering.

Both modules can be either with wheels or with chains or with a combination of e.g. Front chains and rear wheels are equipped. Preferably, however, the chain drive is dealt with here.

The front drive module is now unmanned, has a low silhouette and includes a motor, preferably an automatic transmission, a cooling, a transfer case, a differential and the articulated link drive. Since the front drive module can be made very low and thus forms a smaller signature, the lower silhouette of the probability of the drive in a hostile attack is lower.

The rear mission module includes the driver and the commander as well as the setup of the actual mission module (s). This also causes no engine noise and vibration in or act on the mission module. Since the vehicle division and the weight reduction of the entire vehicle (drive module is built smaller and has no or less armor) can also be used as chain drives rubber tracks, which also minimizes the vibration caused by the chain excitation. In particular, the maintenance and repair is easier because better accessibility to the drive module and thus their components is possible. The use of ABS brakes is now also possible.

The present mobility concept allows best-protected operations in inaccessible areas for other vehicles, is at a high level of protection lighter and structurally smaller than known comparable systems or concepts and has unrestricted roadworthiness. Reference to an embodiment with drawing, the invention and thus the concept will be explained in more detail.

It shows:

1 is a split into two modules vehicle with chain drive,

Fig. 2 is a separated into two modules vehicle with wheel drive.

FIG. 1 shows a vehicle 1, divided into a drive module 2 and a mission module 3. Drive module 2 and 3 mission module are connected to each other by means of a conventional and therefore not shown articulated steering drive 4. Both the steering and, if necessary, the power supply with the mission module 3, which can, however, also be integrated in the mission module 3, as well as the drive of the mission module 3, take place via the articulated-arm drive 4.

The articulated steering drive 4 is for this purpose incorporated on the front housing part 20 of the mission module 3 and on the rear housing part of the drive module 2.

Both modules 2, 3 have their own chains (drives) 5, 6, wherein the chain 7 of the front drive module 2 via the sprocket 5 and a drive train, not shown, driven by a drive motor, not shown, and the chains 8 of the rear module. 3 be moved by the sprocket 6 via the articulated steering drive 4 and a drive train not shown by the drive of the drive module 2.

The mission modules 3 are executed differently depending on their task. In any case, sitting in front a driver and / or a commander who have to drive the vehicle 1 either hatches 9, 10 or under armored protection by periscopes 11 view forward and to the side. About the articulated joint 4 is, as a rule, driven by the driver, the drive module 2 and this steered. The possibility of guiding the commander (passenger) is also provided. Alternatively, the inclusion of cameras on the drive module 2, the attachment to the mission module 3 would be considered sufficient because the drive module 2 is lower than the mission module 3, so that the driver and the commander, which are located under the hatches 9 and 10 , over this can safely recognize the way to go.

Behind the driver and the commander is the mission equipment, not shown here, which is e.g. Seats for use as a crew transporter. For this purpose, on the vehicle roof 21 hatch cover 19 or, not shown here, a weapons station can be accommodated. Alternatives are the formation of the mission module in addition as a medical vehicle, as a radio vehicle or observer, as an ABC vehicle with ABC task, as a weapon carrier with a variety of armament, e.g. a remote-controlled carriage for light and medium machine guns or for a mortar etc. and such tasks as are known from the prior art.

The shell 22 of the drive module 2 and the mission module 3 may be made of ballistic protective materials, e.g. from armor steel or similar composites according to the prior art. The degree of protection according to the planned mission for the different mission modules 3 may be different.

The drive module 2 may have a plurality of openings 15, 16, 17 to supply combustion air for the engine and to supply the engine cooling with the corresponding amount of cooling air. Access to the engine compartment can be made possible by a hatch cover 18.

In a further embodiment, the mission module 3 is only pulled by the drive module 2 and only steered via the articulated link 4, which is not designed as a drive.

Fig. 2 shows an alternative embodiment to the vehicle shown in Fig. 1, wherein in otherwise the same embodiment of the chain drive has been replaced here by a wheel drive. In this case, but not necessarily, each of the axles 13, 14, 15, 16 are driven. In another embodiment, not shown here, the number of axles for the mission module 3 can be increased.
