Abstract: A rear axle radius arm reduces chassis-induced roll oversteer and improves handling and safety both on and off road. Each rear axle radius arm has a single point of frame attachment in a variety of locations, and pivots on a center, allowing lifting to relatively large heights, very large suspension strokes, and high degrees of axle articulation. Four factory axle mounts on the stock axle may be used for many retrofit applications. An additional compliant bushing in the rear axle radius arm accommodates movement in an otherwise fully constrained rear axle suspension design. The additional bushing is another reason why this design improves vehicle performance so much, as it allows for increased axle articulation (differential wheel elevations) with reduced torque applied to the axle and control arm attachment brackets.

Abstract: Disclosed is a suspension using continuous and variable leverage, in which a lever serves as a substitute for an air spring. First, a fulcrum located at the center of the lever is connected to a chassis of a vehicle. An impact transmission plate, which has a convex shape toward the lever and is connected to the upper end of a supporter connected integrally with a non-rotating wheel shaft of a wheel, is located under one end of the lever, and transmits an impact from the wheel to the lever. A spring connected to the other end of the lever absorbs the impact transmitted through the lever. The stronger the impact transmitted from the wheel is, the higher the impact transmission plate pushes up the lever. Then, since the upper surface of the impact transmission plate has a convex shape toward the lever, a pressure point, i.e., a contact point between the lever and the impact transmission plate, is shifted toward the fulcrum of the lever.
