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

    3. The rear trailing arm assembly is installed to the vehicle body with a bracket so that the center of rotation is inside the side member. This raises the center of rotation, reducing the tendency for the rear of the vehicle to lift when braking and ensuring excellent ride comfort.

    4. The rear upper control arm assembly is of hollow 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 rear No. 2 suspension arm assembly has a pressed and welded sheet steel construction, achieving a compact and rigid design.

    7. The lower part of the No. 2 suspension arm assembly is angled to control airflow under the vehicle, contributing to excellent fuel efficiency and vehicle controllability.
