Actuated shock absorber link mechanism with variable link ratio and link form
First Claim
1. A suspension apparatus comprising:
- a first link arm for pivotally mounting at one end on a body frame,a second link arm pivotally mounted at one end to said first link arm and for pivotally mounting at the other end to a rear swing arm, anda shock absorber link arm pivotally mounted at one end in the proximity of a connection portion between said first link arm and said second link arm and for pivotally mounting at the other end to a shock absorber such that said shock absorber link arm is rockable around a pivotal mounting portion provided in the proximity of the connection portion between said first link arm and said second link arm, anda driving means for automatically rocking said shock absorber link arm.

Abstract
A shock absorber link mechanism linking a rear shock absorber to a swing arm of a motorcycle is capable of varying the suspension height and the height of a vehicle. The shock absorber link mechanism includes a first link arm pivotally attached to the frame, a second link arm pivotally attached to a swing arm, a shock absorber link arm pivotally attached to the shock absorber, and an arm connecting shaft. A motor driven actuator varies the link ratio (height) and link form (load characteristic) of the shock absorber link mechanism by rotating the shock absorber link arm via a motion transmission member, pulley, sectoral gear and arm connecting shaft. Further, a sub-wire driven by the actuator compresses the shock absorber when the suspension is lowered.
