a first and a second frame half connected to an articulation that allows the first and the second frame halves to rotate in
relation to one another about a longitudinal axis of the vehicle;
a positioning arrangement comprising at least one adjusting device; and
said positioning arrangement further comprising at least one means of operation operated by said at least one adjusting device
in order to rotate the first and second frame halves about the longitudinal axis of the vehicle into a predefined basic position
in relation to one another and wherein the positioning arrangement has operative and inoperative conditions in which the frame
halves are fixed in the predefined basic position in relation to one another when the positioning arrangement is in the operative
condition and in which the frame halves are freely rotatable in relation to one another when the positioning arrangement is
in the inoperative condition and said inoperative condition is triggered when a predetermined angular difference between frame
halves is determined;
