Title: Three-axle motor vehicle
Inventor: BECKER EWALD DIPL ING
IPC: B62D61/00
Filed: 1984-05-04
Abstract: Fig. 1 shows an arrangement as a four seater. It is a genuine three-axle vehicle in which the four wheels are arranged at the corner points of a lozenge. At each of the corner points of the longitudinal axle - which is the axis of inclination - there is a steering wheel which acts in the opposite direction. At the corner points of the transverse axle - which is the drive axle - there are the drive wheels which take up 70% of the overall weight.   The transverse forces when going round bends are not taken up directly by the chassis but rather by a bar which is connected to the body of the vehicle by a joint above the axis of the centre of gravity. Longitudinal forces on the bar are intercepted by the body of the vehicle through struts. All four wheels roll on concentric arcs. The vehicle inclines to the instantaneous centre. All the wheels always maintain contact with the ground. The smallest turning circle is 5 m. Getting in and out is not impeded by wheel arches. The vehicle is suitable for two seaters, four seaters or eight seaters with the dimensions of a medium size vehicle. <IMAGE>

Title: Drive for rolls and shafts of a folding mechanism
Inventor: REINHARDT WOLFGANG
IPC: B65H45/00
Filed: 1985-01-12
Abstract: The invention relates to a drive for rolls and shafts of a folding mechanism which are mounted adjustable as regards their distance from one another. It is generally known to drive rolls and shafts of a folding mechanism by means of endless belts via belt rollers from a main drive. The disadvantage of this solution is, however, that when jams occur, the folding rolls of the corresponding folding mechanism must be rotated until free. Often the resistance of the jam to the folding rolls is so high that the belt drive slips and the jam cannot be removed. The object is to design the drive for rolls and shafts of a folding mechanism such that even when jams occur the latter can be removed by rotating the drive manually. The object is achieved in that the rolls and shafts of a folding mechanism are connected via a horizontally movable gearing to a handwheel when the folding machine has stopped. <IMAGE>
