FRONT SUSPENSION SYSTEM DETAILS

  1. CONSTRUCTION

    1. Front Suspension Support Sub-assembly

      1. A separate input construction type front suspension support sub-assembly is used.

      2. This construction transmits only the inputs from the front shock absorber assembly and the front bumper spring via the front suspension support sub-assembly to the body. Thus, it achieves superior quietness and ride comfort performance.

      3. The input is transmitted from the front coil spring via the strut mounting bearing to the body.

    2. Front Coil Spring

      1. Both ends of the front coil spring have been formed into a small-diameter, pigtail shape.

      2. The center axis of the front coil spring is slanted toward the outside of the vehicle compared to the center axis of the front shock absorber assembly. As a result, friction and lateral force applied to the front shock absorber assembly is reduced.

        Tech Tips

        Install the front coil spring with the identification paint facing downward of the vehicle.

    3. Front Shock Absorber Assembly

      1. A low-pressure (N2) gas sealed front shock absorber assembly with a multi-leaf type linear control valve is used to achieve both driving stability and riding comfort.

      2. A rebound spring is used to improve roll angle and roll posture.

      3. The area receiving pressure, formerly piston sized, has been widened and the small pressure difference enables the desired damping force to be generated. This achieves an excellent damping force reaction.

        Tech Tips

        To prevent hazardous conditions, make sure to empty the gas from the front shock absorber assembly before discarding the low-pressure (N2) gas sealed in the front shock absorber assembly. For details, refer to the AVENSIS Repair Manual.

      4. The illustration below shows a blow-off type valve damping force characteristics.

    4. Front Lower No. 1 Suspension Arm Sub-assembly

      1. A closed cross section type front lower No. 1 suspension arm sub-assembly that is lightweight and highly rigid is used.

      2. Along with the use of wider treads, the length of the front lower No. 1 suspension arm sub-assembly has been extended.

      3. The installation point of the No. 1 bush and the No. 2 bush characteristics have been optimized to achieve excellent ride comfort and steering characteristics.

    5. Front Stabilizer Bar

      1. A highly rigid, solid type front stabilizer bar is used.

      2. A ball joint is used between the front stabilizer link assembly and the front stabilizer bar, and between the front stabilizer link assembly and the front shock absorber assembly. This helps reduce suspension friction and increase link rigidity. As a result, the ball joints perform effectively even for slight rolling and maintain stable roll feeling.

      3. The surface of the front No. 1 stabilizer bar bush installed in the front suspension crossmember sub-assembly has a saddle shape. This construction, which is embedded into the cross section of the front suspension crossmember sub-assembly, ensures excellent support rigidity.

      4. The front No. 1 stabilizer bar bush has been provided with a dust lip to prevent sand from entering.

      5. To reduce friction, a fluorine coating is provided in the bore diameter of the front No. 1 stabilizer bar bush.
