Abstract: A central articulation with pivot axles standing perpendicularly to one another for a self-driving articulated vehicle comprising two parts which are mutually moveable with respect to one another, whereby the steering is brought about by mutual pivoting of the two vehicle parts with respect to one another about a vertical axle of the central articulation and the adjustment of the vehicle to the unevenness of the ground is brought about by a mutual pendulum course of movement of the two vehicle parts with respect to one another about an axle which is horizontal in the longitudinal direction and a restoring device counteracts the pendulum course of movement of the front car and of the rear car by means of compression springs. Rubber hollow springs are prestressed by means of a tensioning device.
