ABSTRACT:
A novel solid axle front suspension system is disclosed having a staggered shock absorber arrangement which increases and balances shock absorber lever ratios, and provides adequate damping in both vehicle roll and axle pitch conditions. A leaf spring assembly with an elliptical forward bushing improves vehicle suspension noise, vibration and harshness levels. Leaf spring windup is reduced by an axle anti-windup device which is secured at its rearward end to the axle and which includes at its forward end a movable link to the vehicle frame. A bilateral link steering linkage assembly provides improved steering and handling, wherein a tie rod connects the two front steering knuckles together, and a drag link extends from a pitman arm to one of the two steering knuckles at a rearward sweep angle in a substantially horizontal plane. A panard rod extends from the vehicle frame to the solid axle at a rearward sweep angle that is substantially equivalent to the rearward sweep angle of the drag link.
