Abstract

An air suspension system adaptable to various types and sizes of vehicles, including automobiles, trucks, vans and the like, to improve their riding characteristics and stability, including a carrier arm assembly pivotally mounted at one end to the frame of the vehicle and connected near its opposite end to the vehicle axle. The system has an air spring disposed between the first pivotal end of the carrier arm assembly and the axle and interposted between the carrier arm assembly and the vehicle frame so that the air spring supports at least the major portion of the vehicle load and responds to any deflection of the wheels mounted at the opposite ends of the axle. The air suspension system is adjustable relative to the axle and the frame to permit alignment of the axle. The system also includes a means of supplying air to the air spring through independent reservoirs and releases air from the air spring at desired rates to control the compressibility of the spring and the riding characteristics of the system. A separate suspension system is mounted on each of the rear wheels of the vehicle and may include a tracking and torque arm means mounted to permit completely independent susp…
