A coupled torsion beam axle suspension system includes a trailing arm connected to each end of a torsion beam. A vehicle body fastener is mounted at a front end of the trailing arm. A spindle bracket is mounted to a rear outer side of the trailing arm. The vehicle body fastener includes a trailing arm bush at a front end of the trailing arm. A bush link is installed in front of and fastened to the trailing arm bush. A lower mounting bush is formed inside the bush link at a front outer side of the trailing arm bush and fastened to a lower side of a vehicle body. An upper mounting bush is mounted at a rear side of the lower mounting bush and move up and down between the bush link and the vehicle body by a cylinder unit disposed between the bush link and the vehicle body.

Coupled torsion beam axle type of suspension system

A coupled torsion beam axle type suspension system may include trailing arms respectively coupled to opposite ends of a torsion beam, and vehicle body-engaging units, each provided in a front end portion of a respective trailing arm and engaging the respective trailing arm with a vehicle body. Each vehicle body-engaging unit may includes a trailing arm bush that is coupled to a front end portion of the respective trailing arm, a link bracket disposed in front of the trailing arm bush and engaged with the trailing arm bush in a width direction of a vehicle, a vehicle body mounting bush disposed outside of the trailing arm bush and in front of the trailing arm bush, installed in the link bracket, and engaged with a lower part of the vehicle body in a height direction of the vehicle; and a damper connected to the link bracket and the vehicle body abutting the vehicle body mounting bush.

A coupled torsion beam axle type suspension system may includes trailing arms respectively coupled to opposite ends of a torsion beam, and vehicle body-engaging units, each provided in a front end portion of a respective trailing arm and engaging the respective trailing arm to a vehicle body. Each vehicle body-engaging unit may include a trailing arm bush, a mounting link, a rotation mounting bush, an upper mounting bush, an adapter, and a stay.

A coupled torsion beam axle type suspension system may include trailing arms respectively coupled to opposite ends of a torsion beam, a trailing arm bush coupled to a front end portion of the trailing arm, a link bracket mounted in front of the trailing arm bush and engaged therewith in a width direction of a vehicle, and a lower mounting bush mounted outside of the trailing arm bush in front thereof, installed in the link bracket, and engaged with a lower part of the vehicle body in a height direction of the vehicle, and an upper mounting bush offset, with respect to the lower mounting bush, by a predetermined width in the width direction of the vehicle, a predetermined height in a height direction thereof, and a predetermined length in a length direction of the vehicle body.

A coupled torsion beam axle type suspension system (CTBA) may include 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 each of the trailing arms to a vehicle body, wherein each vehicle body-engaging unit includes a trailing arm bush that may be coupled to a front end portion of the trailing arm, a rotation link disposed in front of the trailing arm bush and engaged thereto in a width direction of a vehicle, a slider rotatably connected to a front end portion of the rotation link, and slidable along a length direction of the vehicle body, and a connection link pivotally connecting an outer end portion of the rotation link and the vehicle body.

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.
