ABSTRACT:
A vehicle suspension assembly for tandem drive axles has a suspension system for each axle. Each suspension system incorporates two lower torque beams on each side of the vehicle and a single central upper torque rod. A central hanger is mounted between the two axles. The lower torque beams are pivotally connected between the hanger and an axle seat. A straddle bracket connects the axle to the axle seat in a hinged fashion. The upper central torque rod is connected between the upper side of the axle housing and the chassis. The lower torque beams act as a parallelogram to stabilize the axle seat. They also act together with a portion of the axle seat as a composite lower torque rod cooperating with the upper torque rod to stabilize the axle.
