Abstract
A suspension assembly for a vehicle that has a rear-mounted engine and a longitudinal frame member and an axle below the frame member with a bolster beam connected to the axle and air springs connected between the ends of the bolster beam and the frame member. There are outrigger members to locate the air springs outboard for better stability. An upper torque rod and a lower torque rod are arranged parallel to one another and are connected between a bracket assembly on the bolster beam and a bracket assembly supported by the frame member. The torque rods are staggered from one another in three planes. The upper torque rod is forward of the lower torque rod and is outboard of the lower torque rod. Likewise, the forward ends of the torque rods are outboard of the rearward ends. This arrangement significantly enhances the overall stability of the suspension system.
