Abstract
AbstractThe balanced suspension with rubber springs is widely used in heavy articulated dump truck’s chassis to improve the power performance and the passing ability of vehicle. However, the congenital kinematics interference of the absorber and the guide linkage is in existence because of the natural structural feature of this kind of balanced suspension. On the basis of former dynamic analysis of the chassis’ ride comfort by using vibration theory, the principle of mechanism kinematics is used to analyze the characteristics and the law of such a suspension system in this chapter. The kinematics sketch of the balanced suspension is obtained by way of hypothesis and simplification; the kinematics equations of the balanced suspension are further deduced; the relative movement law and the ways to reduce the interference are analyzed and surveyed by calculating the equations. It is concluded that it is beneficial to reduce the kinematics interference and prolong the life of the absorber and the guide linkage if the Guiding mechanism is parallel to X axis, and Panhard rod is parallel to Y axis of the vehicle coordinate while designing such balanced suspension. Compared with other chapters of the author, the kinematics interference of Panhard Rod was firstly analyzed in this chapter. However, the theoretical result needs more experimental support.KeywordsBalanced suspensionGuiding mechanismKinematicsInterference
