BRIEF ANALYSIS ON REAR MOTORBIKE SUSPENSION MECHANISM

摘要

Rear wheel suspension which is also driving significantly influences motorbike dynamic performances. Rear mechanism design largely evolved in the latest years, especially by interposing a mechanism, named suspension mechanism between the wheel oscillating arm and spring-bumping block. That influences the kinetic transmission ratio and the transmission ratio of forces between rear wheel and the spring-bumping block of the main suspension. The paper defines these elements, it makes the structural and kinetic analysis of the representative suspension mechanisms and it outlines the influence of the design of these mechanisms on the main suspension.
