DRIVE BELT SUSPENSION FOR SNOWMOBILE

摘要

A drive belt suspension system for a snowmobile includes an improved construction in which an excessive shock is not directly received by the snowmobile frame to ensure a smooth operation of the suspension system. The suspension system includes a suspension aim arranged to suspend a slide rail assembly from a frame assembly of the snowmobile body. The suspension arm has a sleeve connected to the slide rail assembly for pivotal movement about a lower axis and a rod connected to the frame assembly for pivotal movement about an upper axis. The rod is supported by the sleeve and has a pair of stoppers that interpose the sleeve therebetween. The lower axis is positioned between the respective stoppers in a direction parallel to a longitudinal dimension of the drive belt suspension system.
