본 발명은 차량 서스펜션용 보이드 부시에 관한 것으로, 내측스토퍼(320)에 형성된 내측요철(400)과 외측스토퍼(330)에 형성된 외측요철(500)이 서로 직교되는 방향으로 형성되어서 서스펜션의 거동시 서로 점접촉하고, 내측요철(400)끼리 서로 평행하지 않게 형성되고 외측요철(500)끼리 서로 평행하지 않게 형성된 구성으로, 내측요철(400)과 외측요철(500)의 접촉면적을 크게 줄일 수 있으면서 접촉 마모위치를 다변화할 수 있게 됨에 따라 내구성 향상 및 수명 증대를 도모할 수 있도록 된 것이다.

    A void bush for a vehicle suspension includes: inside bumps (400) formed in an inside stopper (320) and outside bumps (500) formed in an outside stopper (330). In particular, the inside bumps (400) and the outside bumps (500) are configured to cross perpendicularly to each other to allow the inside bumps (400) and the outside bumps (500) to be brought into point-contact with each other during behavior of the suspension. The inside bumps (400) are not arranged in parallel to each other and the outside bumps (500) are not arranged in parallel to each other. Accordingly, contact area between the inside bumps (400) and the outside bumps (500) is greatly reduced and contact abrasion positions therebetween are diversified so that durability and lifespan of the void bush are improved.
