COUPLED TORSION BEAM AXLE TYPE SUSPENSION SYSTEM

摘要

Disclosed is a coupled torsion beam axle type suspension system. In the system, trailing arms are respectively connected to both ends of a torsion beam, and each of the left/right trailing arms has a vehicle body coupling unit to allow the system to be mounted on the vehicle on an end thereof. Also, a spring sheet and a shock absorber pin to allow a spring to be mounted thereon is disposed in the rear side of the system, and a spindle bracket for mounting a carrier is disposed at the rear outside of the system. The vehicle coupling unit includes: a training arm bush integrated with the end of the training arm; a rotary link disposed at the front side of the trailing arm bush and coupled to the trailing arm bush in parallel with the width direction of the vehicle; and two connection links connecting the front end and outer end of the rotary link to the vehicle so that a central point of instantaneous rotation of the rotary link is defined at the outside of the rotary link in the width direction of the vehicle.
