Abstract
An assembly for enabling rotational motion in a vehicle or mobile working machine is disclosed which includes at least two sections arranged in an overlying position relative to the vehicle's or working machine's working surface. A top section can be led to motion relative to a bottom section and a longitudinal rotation axis, the top section and the bottom section being movably coupled to each other by at least one trajectory element which generates a curvilinear trajectory. The relative motion of the top section and the bottom section proceeds along a curvilinear trajectory in a section plane which is perpendicular relative to the lengthwise rotation axis. The trajectory can be at least partly in the shape of a circular arc, the midpoint of this curvilinear trajectory being disposed below the bottom section. An actuator mounted on the vehicle or working machine affects the top section and/or the bottom section.
