REAR SUSPENSION SYSTEM


  1. CONSTRUCTION


    1. High tensile strength pressed sheet steel is used for the rear trailing arm assembly, rear upper control arm assembly, rear No. 1 suspension arm assembly and rear No. 2 suspension arm assembly, achieving both weight reduction and structural rigidity.

    2. A forked rear No. 1 suspension arm assembly is used. The angle of the shock absorber has been optimized so that it sits between the forks to accommodate the low floor design.

    3. The rear No. 2 suspension arm assembly has a pressed and welded sheet steel construction, achieving a compact and rigid design.

    4. The rear upper control arm assembly has a welded T-shape construction, achieving a reduction in weight and good structural rigidity.

    5. A protruding shaped inner tube bush is used in the rear upper control arm assembly, rear No. 1 suspension arm assembly and rear No. 2 suspension arm assembly, reducing the torsion stiffness of the bush while maintaining lateral rigidity, ensuring decreased road noise and excellent suspension response.

    6. The size of the axial holes in the trailing arm bush are optimized to reduce shock generated while driving on an uneven road surface.

    7. Rear suspension arm covers are attached to the rear No. 1 suspension arm assembly and rear No. 2 suspension arm assembly to control airflow under the floor of the vehicle, contributing to excellent fuel efficiency and vehicle controllability.
