摘要: A suspension unit (10) for supporting a cab on the chassis of truck has two U-shaped yokes (20, 24), one with arms (28, 30) extending down and other (32, 34) up. The yoke (24) are nested within (20) in sliding fit bearing (46) vertical slot (44) connects each pair adjacent (30, 34, 28, 32). An air spring (62) or shock absorbers (59) can be mounted between 24). guideway (52) having bottoming rib (56) stop element (56') cushioning pad (84) is formed arm corresponding received abuts fully compressed position to prevent excessive loads (62), bearings (46). (16) (14) 32) fore aft, provide relatively free movement, pivoting about aft axis (47), translational rigidity relative (14).
