Device for connecting two, each individually operable, with an internal combustion engine equipped vehicle units to form a single vehicle, preferably a tracked vehicle.

The innovation relates to a device for connection

J two, each more operable by itself, with an internal combustion engine equipped vehicle units to form a single vehicle, preferably a tracked vehicle, which in particular is intended for driving on and working on snow-covered surfaces.

Tracked vehicles are generally used for driving on rough roads Terrain used, that is, where the terrain is driven on with conventional trucks, tractors or even passenger cars is no longer possible.

In recent times it has also been recognized that considerable driving results can also be achieved when using caterpillar vehicles on snowy terrain, with the caterpillar vehicles above all being too manageable. use jen purposes is η are, for example, to transport people, loads, foodstuffs or the like. in, for example, previously economically undeveloped: mountain regions, so that in this way, previously unknown ski areas should also be accessible.

Tracked vehicles were already being used for machining and manufacturing used by ski slopes and as a transport vehicle for skiers.

For the varied use of such crawler vehicles, it can be a condition for them, on the one hand, to have a considerable vehicle width to have, for example, as many slope preparation devices as possible, arranged side by side, drag to be able to, i.e. to achieve the widest possible ski slope in one operation.

On the other hand, however, this considerable vehicle width can be undesirable when it comes to driving over such a crawler vehicle often found narrow entrances to the machining

to be able to drive. This applies in particular to the often unavoidable access via public transport busy roads, where such wide caterpillars the officially approved vehicle width and thus obstructing the traffic would exceed by a considerable amount

If at all possible, one would be forced to put such a wide caterpillar vehicle on a separate feeder vehicle to be loaded, or one would be forced to dismantle the wide caterpillar vehicle into individual parts for the purpose of transport, so that it would then have to be put back together again at the destination.

These disadvantages inherent in a relatively wide caterpillar vehicle could be overcome by choosing a relatively narrow, substantially eliminate the conditions of public transport taking into account caterpillar vehicle, which can definitely find a justified application where there is a need to drive on narrow access roads, and where it continues applies, for example, to transport only relatively low transport loads or a small number of people.

Based on the above considerations, the object of the innovation is to create a device which

6.2.7ο - 4 -

alternatively is able to use a relatively wide or a relatively narrow caterpillar vehicle for a variety of uses to create with the resulting advantages, which two types of vehicle are their own.

Furthermore, according to the innovation, the device should be constructed in a relatively simple, uncomplicated and cost-saving manner.

Based on a solution according to the type mentioned above, suggests the innovation for this essentially that the two vehicle units in a parallel and in the same Distances to each other arranged end position by one or more and of at least one qaerverschieblich arranged pipe section formed pipe plug connections can be coupled.

Here, each of the two vehicle units can fully be operational. Each of the two vehicle units can be fitted with a relatively wide caterpillar that generates the propulsion be equipped. When coupled together, you can Rotary movements of the caterpillar vehicle, for example, when one of the two accelerates to a vehicle unit associated internal combustion engines or brought about by braking the caterpillars of one of the two vehicle units will.

The device according to the innovation allows a vehicle width that does not impede public traffic in the closed state. läfit other hand dj.e possibility to beyond this wheel spacer, depending on the or querv ^r rjchiebiichen Rohrabschaitte can be extended by one or both facing sides of the two vehicle units how far or extended -nd.

In a further development of the innovation, it is provided that on each vehicle unit across its entire width or to attach a transverse tube extending beyond that for the reception of one or more of the tube section connections Pipe sections.

A good off-road mobility of the crawler vehicle is further achieved by means of the device according to the invention. that each vehicle unit can be pivoted with a cross tube around the respective Mitteilängsacnse of the pipe connector is.

According to the innovation, both cross tubes and thus both vehicle units can continue through a common one around the central longitudinal axes the cross tubes pivotable bracket can be connected.
