SADDLE RIDING ROLLING VEHICLE WITH LOADING SURFACE INTEGRAL WITH THE LOWER CROSS MEMBER AND HOUSED BETWEEN THE FRONT STEERED WHEELS

The motor vehicle comprises two front steering and rolling wheels (4, 4′) and at least one rear rolling wheel (9). The motor vehicle comprises a roll four bar linkage (10) connected to a frame (2A-2B) and which supports the front steered wheels (4, 4′). A suspension group (71, 71′) is interposed between the front wheels (4, 4′) and the roll four bar linkage (10) to allow movement of the front wheels with respect to the roll four bar linkage (10). The roll four bar linkage (10) comprises: a lower cross member (11) and an upper cross member (12) hinged to the frame to pivot around first roll axes (101, 101′); and a right upright (21) and a left upright (21′) hinged to the cross members (11, 12) so as to rotate around second roll axes (212, 212′, 221, 221′) parallel to the first roll axes (101, 101′). The lower cross member (11) extends along a longitudinal direction between the front wheels and beyond said front wheels to form a loading surface.
