摘要： Tandem axle suspensions comprising transversely spaced pairs of bellcranks fulcrumed on adjacent transverse axes to a vehicle frame and having platelike substantially horizontal arms extending longitudinally in opposite directions from their fulcrums, and upright arms having means resiliently biasing the upright arms away from each other through axles secured to corresponding outer ends of the horizontal arms, the horizontal arms lying in longitudinal substantially vertical planes and being torsionally sufficiently flexible to permit transverse tipping of the through axles for operation over irregular surfaces. In one embodiment of the invention, the upright arms are rigid members, with longitudinally acting springs compressed between their upper ends, while in another embodiment the upright arms are semielliptic leaf springs rigidly secured at their lower ends to the horizontal arms and connected by a short strut to each other at their upper ends.

摘要： An air leveling system for a vehicle wherein a check valve is connected between independent front and rear air lines for respectively feeding pneumatic pressure to front and rear shock absorbers. At least when the pneumatic pressure of the rear side shock absorbers is excessively higher than that of the front side shock absorbers, the pneumatic pressure at the rear side is discharged by the check valve to balance the pneumatic pressures at the front and rear sides to thereby hold the vehicle height at a predetermined level. The system provides for automatic correction of imbalance between the vehicle heights at the front and rear sides, particularly when the rear vehicle height is higher.

摘要： This invention relates to a suspension for tandem axles of a truck or trailer. A pair of beams are journaled on a common trunnion. On one end of each beam a vertically flexible member depends downwardly into contact with the upper portion of the other beam intermediate one end of the other beam and the trunnion. Both flexible members are simultaneously flexed at both ends during increase of load on the suspension and traversal of irregularities on the road.
