Samenvatting
For the theoretical investigation of the influences of constructive data on the oscillation tendency of vehicles (tractors) with one-shaft caravans is built up a replacement system. Thereby are investigated first of all the course-keeping characteristics of the tractor and the influence of the trailer on the tractor-vehicle. The oscillation behaviour is treated to begin for the single parts and after that for the tractor. A variation of the constructive data shows that the tendency to oscillations may be decreased.
