Title:
SUSPENSION
Document Type and Number:
WIPO Patent Application WO/2017/130919
Kind Code:
A1
Abstract:
In order to make it possible to apply a greater damping force than with conventional suspensions while also decreasing thickness, a damper (60) is provided toward the side of an upper frame (10), which is a main vibration member supported at the tops of a front link (30) and a rear link (40) in a frame linking mechanism, so as to serve as an accessory vibration means that generates vibrations with a behavior different from the vibrations in the upper frame (10) which are generated by the rotational movements of the front link (30) and the rear link (40). When the upper frame vibrates due to input vibrations, the damper (60) exhibits a different vibrational behavior; thus, the energy of the input vibrations is not only dispersed as the vibrational energy of the upper frame (10) and the thermal energy generated by the expansions and contraction of the damper (60), but is also consumed as the energy that induces the vibration of the damper (60) itself, which is provided as a vibrating member. As a result of having such a structure, the damper (60) improves the basic performance of the suspension in terms of the vibration absorption characteristics and shock absorption characteristics thereof.
