Title:
SUSPENSION
Document Type and Number:
WIPO Patent Application WO/2018/105713
Kind Code:
A1
Abstract:
The present invention is capable of applying a damping force greater than in the prior art and achieves a further reduction in thickness. A damper 60 is provided on the upper frame 10 side so as to serve as a sub vibrating body, the upper frame 10 serving as a main vibrating body which is supported by the top of the front link 21 and the rear link 22 of a frame link mechanism 20, and the sub vibrating body generating vibrations with behavior different from the vibrations of the upper frame 10 generated by the rotary movement of the front link 21 and the rear link 22. When the upper frame is vibrated by input vibration, the energy of the input vibration is not only distributed as vibrational energy of the upper frame 10 and heat energy generated by the expansion and contraction of the damper 60 but is also consumed as energy for vibrating the damper 60 itself, which is provided as a vibrating body, due to the different vibrational behavior exhibited thereby. This arrangement structure of the damper 60 improves the basic performance of vibrational absorption characteristics and shock-absorbing characteristics of the suspension.
