<p>A utility vehicle (10) comprising a cab (12) mounted to a frame (14) by cab suspension means (16) is provided. The cab suspension comprises rolling linkage (20) which permits only circumferential movement of the cab around a generally longitudinal axis (24;44), and vertical linkage (22) which permits only radial movement of the cab relative to said axis (24) or radial movement of the axis (44) relative to the frame. The rolling linkage and vertical linkage are connected in series between the cab and the frame thus allowing independent resolution of rolling movement and vertical movement. The cab suspension means further comprises two spring/dampers (28,38; 58,38) arranged to independently control the stiffness and damping within the two degrees of freedom, namely roll and vertical movement.</p> |
