Description

are attached to the ski-shaped spring bodies 1 by gluing or in some other way. The carrying wheels 5 are supported against the bottom part of an endless treadmill 2, which in the present case Embodiment provided jointly for both ski-shaped spring bodies and the pairs of supporting wheels 5 is. Deflection rollers 3 are arranged at the ends of the vehicle, of which the rear deflection roller is driven by a motor 6, the motor 6 being carried by the vehicle frame 7. As 1 and 4 show, the vehicle frame 7 lies against the central part of the ski-shaped spring body that bears the entire vehicle body and the load. The load is thus over the whole Length of the spring body 1 evenly distributed over the support members 5 of the vehicle on the treadmill 2.

F i g. 1 also shows that the vehicle body is subdivided in its longitudinal direction by articulation points 8 which enables adaptable off-road driving. The designated with 9 Vorrichrungen show schematically how the outer parts of the vehicle frame 7 from the middle part of the vehicle frame can be worn.

In the embodiment shown in Figure 2 is the vehicle body through a pivot point 8 in

ίο divided into two parts. Forms a transverse rail an abutment 10 which limits the pivoting of the rear part downwards. The rail can also serve to make the corresponding spring body section a concave or convex To give shape, whereby the adaptability of the vehicle in the field and its traction or Climbing ability is improved.
