<p>A vehicle cab suspension unit (10) has a foundation (14) which is secured to an outer rail (R) of the frame of the vehicle and pivotally connects one end (60) of a track arm (22). The other end (68) of the track arm is supported above the foundation (14) by an air spring (16), and a cab support yoke (12) is pivotally connected between the ends (60, 68) of the track arm (22) so as to support and secure the cab at a position along the track arm (22) between its ends (60, 68). Shock absorbers (18, 20) are provided between the foundation (14) and the cab support yoke (12) on both sides of the track arm (22). A height control valve maintains the height of the suspension unit (10) and elastomeric snubbers (34) on the foundation (14) provide limits to the range of travel of the unit (10).</p> |
