According to the present invention, a non-tilting CTBA system (100) or a tilting CTBA suspension system (100-1) has a bush mass (4) between a bush pipe (3) causing rotation and a bush core (2) which does not cause rotation with respect to an external load, and employs a CTBA bush (1) including a rigid control section unit (5) combining an asymmetric bridge structure formed by a cross-shaped mass body (4A) of the bush mass (4) to increase handling performance and riding comfort performance together and a gap addition securing cross-section structure formed on the inner circumferential surface of the bush pipe (3) to increase lateral rigidity and lateral steering performance together to optimize axial rigidity and front/rear rigidity which are contradicting performance factors of the CTBA bush (1) by a combination to greatly improve riding and handling (R&H) performance while lateral rigidity and lateral steering performance are maintained.

    본 발명의 논틸팅 CTBA 시스템(100) 또는 틸딩 CTBA 현가 시스템(100-1)은 외부 하중에 대해 회전을 발생시키지 않는 부시 코어(2)와 회전을 발생시키는 부시 파이프(3) 사이에 부시 매스(4)가 구비되고, 횡강성 성능과 횡 스티어 성능이 함께 높아지도록 상기 부시 파이프(3)의 내주면에 형성된 갭 추가 확보 단면 구조 및 핸들링 성능과 승차감 성능이 함께 높아지도록 상기 부시 매스(4)의 X자 매스 바디(4A)로 형성된 비대칭 브릿지 구조가 조합된 강성 조절 구간부(5)를 포함한 CTBA 부시(1)가 적용됨으로써 CTBA 부시(1)의 상충 성능 인자인 축방향 강성과 전후 강성을 상호 조합으로 최적화하여 횡강성과 횡 스티어 성능이 유지된 상태에서 R&H(Riding and Handling) 성능이 크게 향상되는 특징을 구현한다.
