Chapter 4 Kinematics and KC Experiment of a Rectilinear Rear Independent Suspension

摘要

A rectilinear rear independent suspension (RRIS) which has the ability to remain the wheel alignment parameters (WAPs) invariable in theory is presented in this paper. The kinematic analysis of the RRIS indicates that the WAPs are not sensitive to the hardpoints and the compensation length is much less than the suspension travels. In order to investigate the actual WAPs, the K&C experiment of the RRIS and twin-trapezoidal link suspension (TTLS) were carried out. The comparison results indicate that the RRIS has better WAPs and smaller forces along both lateral and longitudinal directions, which could reduce the tire wear and enhance the handling ability in application.
