COUPLED TORSION BEAM AXLE TYPE SUSPENSION SYSTEM

摘要

Disclosed is a coupled torsion beam axle type suspension system. In particular, the coupled torsion beam axle type suspension system includes trailing arms respectively coupled to opposite ends of a torsion beam and a vehicle body-engaging unit provided in a front end portion of each of the trailing arm and engaging the trailing arm to a vehicle body. Each vehicle body-engaging unit includes a trailing arm bushing that is coupled to a front end portion of the trailing arm, a rotation link disposed in front of the trailing arm bushing and engaged thereto in a width direction of a vehicle, and a pair of connection links configured to respectively couple front and outer end portions thereof to the vehicle body, such that an instantaneous rotational center point of the rotation link is formed outside of the rotation link in the width direction of the vehicle.
