1. A motor vehicle comprising:
a forecarriage rolling about a roll axis;
a rear carriage having two non-rolling rear driving wheels;
a linkage system for connection between the rolling forecarriage and the rear carriage;
wherein the linkage system comprises:
a left upright pivoted to the rear carriage about a left lower pivot axis;
a right upright pivoted to the rear carriage about a right lower pivot axis;
an upper cross member, pivoted in an upper point of the left upright about a left upper pivot axis, and pivoted in an upper point of the right upright about a right upper pivot axis;
an intermediate cross member, pivoted to the left upright about a left intermediate pivot axis arranged between the left lower pivot axis and the left upper pivot axis; and pivoted to the right upright about a right intermediate pivot axis arranged between the right lower pivot axis and the right upper pivot axis wherein the intermediate cross member is hinged to the forecarriage about a lower central pivot axis and the upper cross member is hinged to the forecarriage about an upper central pivot axis;
wherein the distance between the lower central pivot axis and the upper central pivot axis is approximately equal to the distance between the left intermediate pivot axis and the left upper pivot axis and to the distance between the right intermediate pivot axis and the right upper pivot axis;
wherein, in an erect and non-rolling position of the vehicle on a supporting surface, the lower central pivot axis lies under a plane on which the left intermediate pivot axis and the right intermediate pivot axis lie, and the pivot axes of the linkage system lie on vertical planes parallel to a vertical median plane of the motor vehicle, on which the lower central pivot axis and the upper central pivot axis lie.
