Title:
SUSPENSION SYSTEM FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2013/031623
Kind Code:
A1
Abstract:
A suspension system of the present invention comprises a ball screw (4), an acceleration mechanism (5), and an electromagnetic motor type braking force generator (6). The present invention uses an electromagnetic motor type buffer which controls a linear motion of a shaft (7) by converting the linear motion of the shaft (7) of the ball screw (4) into a rotary motion of a ball screw nut (8), transmitting the rotary motion to a motor rotor (29) of the braking force generator (6) after accelerating the rotary motion with the acceleration mechanism (5), and the braking force generator (6) generating a force in a direction in which the rotary motion is controlled. One or more components constituting at least one of the ball screws (4), the acceleration mechanism (5), and the braking force generator (6) may be used as a component constituting at least two of the ball screw (4), the acceleration mechanism (5), and the braking force generator (6).
