Abstract
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 rolling 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 rolling four-bar linkage (10) to allow movement of the front wheels with respect to the rolling four-bar linkage (10). The rolling 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 and above the upper cross member (12) so as to carry a load above the upper cross member.
