ABSTRACT OF THE DISCLOSURE Light and heavy duty vehicles, such as trailers, require spring suspension systems to mount wheels thereto. A problem in the spring suspension systems prior to this invention has been that they are permanently mounted on the frame of the vehicle which makes serviceability time consuming and expensive. The spring suspension system of this invention overcomes this problem by being readily assembled and removed from the vehicle frame and includes a torsion spring cartridge assembly for supporting an oscillating member. The assembly includes a bearing assembly, a torque assembly mounted for rotary motion in said bearing assembly, a counter-torque hub, and a set of torsion bars connecting the torque assembly to the counter-torque hub. The cartridge assembly is adapted to be removably mounted in a support structure with the bearing assembly and counter-torque hub mounted in a fixed relation so that the torque assembly is free to rotate within the limits of the torsion bars. A dampener can be provided to restrict the motion of the torque assembly in one direction of motion.
