Abstract

A tricycle with independently-suspended rear wheels and having a rocking mechanism and a single shock absorber used to effect the damping action of both the left and the right suspension arms connected to the rear wheels. The left and right suspension arms are connected by a shock absorber and arcuate links and bell cranks provided at the opposite ends of the shock absorber. In response to upward and downward movement of the left and right suspension arms, the single shock absorber can be expanded and contracted to effect damping action of the left and right suspension arms. Accordingly, weight and cost can be reduced when compared with a conventional tricycle having two shock absorbers, one provided for each of the left and right suspension arms.
