To provide a bush with improved degree of freedom for tuning, which can shorten a development load for target performance of R&H/NVH/steering/endurance that a vehicle requires in a suspension system, and can satisfy optimization of the development load, and provide a suspension system.SOLUTION: A bush 1 with improved degree of freedom for tuning applied to a suspension system 100 of the present invention has a bush elastic modulus in which a plastic elastic modulus of a second inner pipe 30 and a rubber elastic modulus of a rubber part 60 are combined. The bush is characterized in that rigidity tuning based on the plastic elastic modulus and elastic tuning based on the rubber elastic modulus are combined to increase the degree of freedom for tuning, so that a development load for optimizing target performance of R&H/NVH/steering/endurance is shortened while it is easy to increase the rigidity in an axial direction and the rigidity in a rotational direction and decrease the rigidity in a front-rear direction and a vertical direction.SELECTED DRAWING: Figure 1
【課題】車両が懸架システムで要求するR&H/NVH/操舵/耐久の目標性能のための開発ロードの短縮とともに、最適化も満足可能なチューニング自由度改善型ブッシュおよび懸架システムを提供する。【解決手段】本発明の懸架システム100に適用されたチューニング自由度改善型ブッシュ1は、第2内パイプ30のプラスチック弾性係数とラバー部60のラバー弾性係数とが組み合わされたブッシュ弾性係数を有し、前記プラスチック弾性係数による剛性チューニングと前記ラバー弾性係数による弾性チューニングとが組み合わされてチューニング自由度を高めることにより、軸方向の剛性および回転方向の剛性増大と前後方向および上下方向の剛性低下が容易でありながらも、R&H/NVH/操舵/耐久の目標性能最適化のための開発ロードが短縮されることを特徴とする。【選択図】 図1
