摘要:
A wheel assembly adapted for connection to a chassis (2) has a first trailing arm (28) pivotally suspended, from a first end, to the chassis (2); a first wheel mounting stub axle (26) located at or adjacent to the free end of the trailing arm (28); and a first connection means (32,33) located adjacent the first wheel mounting stub axle (26). The assembly further comprises a second trailing arm (29) pivotally suspended from a first end to the chassis (2) and having its second end free and angled with respect to the chassis (2) in the same direction as the first trailing arm (28); a second wheel mounting stub axle (27) located at or adjacent the free end of the second trailing arm (29), a second connection means located adjacent the second wheel mounting stub axle (27); a first bracket (36) located on the chassis (2), between the the first and second trailing arms (28 & 29); a second bracket (39) located on the chassis (2) on the one side of the first bracket (36) beyond the first wheel mounting stub axle (26), a third bracket located on the chassis on the other side of the first bracket (36) beyond the second wheel mounting stub axle (27); a pivoting linkage (37) connected to the first bracket (36) and extending on each side thereof, a first leaf spring (35) connected between one end (38) of the pivoting linkage (37) and the second bracket (39) with the first connection means (32,33) of the first trailing arm (28) connected to the middle of the first leaf spring (35); and a second leaf spring (40) connected between the other end of the pivoting linkage (37) and the third bracket, with the second connection means (31) of the second trailing arm (29) connected to the middle of the second leaf spring (40).
摘要:
A suspension for two-rear-axle vehicles which can dislodge a vehicle, even when its driving wheel on one side runs on a different-level place, by lowering the rigidity of a first stabilizer (42) provided on a driving axle (5) of rear axles below that of a second stabilizer (52) provided on a driven axle (6). The rigidity of the first stabilizer (42) provided in an axle case (13) which supports the driving axle (5) rotatably is lowered below that of the second stabilizer (52) provided in an axle case (14) which supports the driven axle (6) rotatably. The rigidity of the stabilizers can be changed, for example, by changing the diameter of a torsion bar (43) supported pivotably on the axle cases (13, 14). Even when a driving wheel on one side mounted on the driving axle (5) runs on a different-level place, the torsional moment of the first stabilizer (42) is too small to lift the other driving wheel off the ground.

摘要:
A suspension system (10) for compensating road-borne loads applied selectively to one end of a vehicle wheeled axle (12). The suspension system (10) includes a pair of elongated rigid tube (56,58), extending longitudinally over oposite sides of the wheels axle (12), and supported thereover by corresponding upright posts (26,28) anchored to the intermediate section of the wheel axle (12). Each post and associated tube have a number of lateral interdigitating hollw ears, wherein the tube and post are pivotally interconnected by a lengthwise rubber shaft (80,86). A bottom frame beam (42,44) from the vehicle body extends laterally outwardly of each corresponding tube, and includes a plurality of ears interdigitating with additional ears from the proximate tube for through engagement by another rubber shaft (82,84), for pivotally interconnecting the beam to the tube. In normal condition, each beam ear rubber shaft is downwardly offset relative to the post ear rubber shaft. Thus, as the axle (12) on one side of the vehicle is lifted following a road-borne load, the vehicle beam (56,58) on that side will sink as well as move inwardly toward the intermediate portion of the axle (12), due to the deformation of the rubber shaft, whereas the vehicle beam on the opposite side will raise as well as move outwardly away from the intermediate axle portion.
