Increased roll stability suspension system
A suspension system is described for suspending an elongated chassis of a vehicle, such as a heavy duty truck, above the front axle and rear axle of a transversely extending tandem axle combination. The suspension system comprises: means for locating the roll center of the vehicle at an elevation below the elevation of the axles; and a stabilizer unit for providing roll stability to the vehicle. The stabilizer unit is mounted to the vehicle chassis at a pivot point longitudinally intermediate the front axle and the rear axle of the tandem axle combination for rotation in a generally horizontal plane. The stabilizer unit includes a pair of linkage members, each linkage member extending generally longitudinally outward from the pivot point in a direction opposite from the other linkage member and toward a corresponding axle.
