The present invention relates to a buffer rubber spring structure. In accordance with the present invention, a support plate (41) is fixed to one side of an upper side of a lower flat spring bundle (30) through a first bolt (44) or a second bolt (45) in a space between rear ends of an upper flat spring bundle (20) and the lower flat spring bundle (30), a pair of left and right square rings (42) are fixed to both left and right ends of the support plate (41), and a rubber rod (43) is supported in the pair of left and right square rings (42) to be moved forward and backward and left and right and, accordingly, when a small cargo truck or the like is driven on an unpaved road and a road with a number of puddles or speed bumps, the buffer rubber spring structure can absorb a large shock or vibrations while reducing the rolling of the vehicle body. Therefore, the buffer rubber spring structure is capable of reducing fatigue during driving as well as increasing the lifespan of a shock absorber installed on a rear wheel and reducing the cutting of a flat spring, which can lead to an enhancement in safe driving.

    본 발명은 상부 판스프링 뭉치(20)와 상기 하부 판스프링 뭉치(30)의 후측단 사이 공간에 하부 판스프링 뭉치(30)의 상면 일측에 제1 볼트(44) 또는 제2 볼트(45)에 의해 지지판(41)이 고정되고, 이 지지판(41)의 좌우 양 끝단에 좌우 한 쌍의 사각링(42)이 고정되고, 좌우 한 쌍의 사각링(42) 내에 전후 및 좌우 이동되도록 고무봉(43)이 지지되는 완충 고무스프링 구조체로 이루어져 있기 때문에 소형 화물트럭 등이 비포장도로 및 웅덩이가 많은 도로 또는 과속 방지턱 등으로 주행할 때 발생되는 큰 충격과 진동을 흡수함과 동시에 차체의 롤링을 감소시켜 줄 수 있으므로, 운전 중 피로감을 줄여 줌은 물론 후륜측에 설치되어 있는 충격 흡수장치(shock absorber)의 수명을 증가 시키고 판스프링의 절단을 감소 시키는 등 안전운행을 도모할 수 있는 장점이 있는 것임.
