Abstract: A vehicular suspension enhancement that comprises the addition of a pair of cellular polyurethane elastomer cylindrical shaped springs, one located on each side of an axle. Each spring is operatively attached between the axle and the vehicular frame and made from a cast of cellular polyurethane elastomer derived from a polyol diisocyanate mixture containing naphthalene-1,5-diisocyanate (NDI)-terminated prepolymer and a polyol selected from the group consisting of polyether polyol, polyester polyol, or a combination thereof.
Abstract: A vehicular suspension enhancer comprises a pair of vertically oriented spring portions, one portion mounted to the axle and the other portion mounted to the frame. Each vehicle axle can be equipped with two suspension enhancers, one enhancer located on each side of an axle. Each of the spring portions are positioned in the space between the axle and the vehicular frame, with the distal ends of each spring portion facing one another with a space between the distal ends defining a gap. The gap between the facing spring portions will increase in response to an increase in the distance between frame and axle.
