The present invention relates to a caterpillar type moving object designed to travel a rough road, and in particular solves a problem that can be generated when foreign substances are introduced into a track roller of a moving object. The present invention for achieving the object provides an apparatus for preventing foreign substances from being introduced into a track roller that rotates a caterpillar in a track, the apparatus including a shaft of a track roller, a shell located at the circumference of the shaft to be rotated, a collar located at opposite ends of the shell while being fixed to the shaft, a floating seal assembly mounted inside a gap formed between the shell and the collar to prevent a lubricant between the shaft and the shell from being leaked, and a seal mounted outside a point at which the floating seal assembly is mounted to close or open the gap according to a temperature.

    본 발명은 험로를 주행하기 위해 설계된 캐터필러식 주행체에 관한 것으로서, 특히 캐터필러식 주행체의 트랙롤러에 이물질이 유입되어 발생할 수 있는 문제점을 해결할 수 있게 구성한 것이다. 상기와 같은 목적을 달성하기 위한 본 발명은 캐터필러를 궤도 회전시키는 트랙롤러의 내부로 이물질이 유입되는 것을 방지하기 위한 장치로서, 트랙롤러의 샤프트와, 샤프트의 둘레에 위치하여 회전하는 쉘과, 샤프트에 고정된 상태로 쉘의 양단에 위치하는 칼러와, 쉘과 칼러의 사이에 형성된 갭의 안쪽에 장착되어 샤프트와 쉘 사이의 윤활유가 누유되는 것을 차단하는 플로팅 씰 어셈블리와, 플로팅 씰 어셈블리가 장착된 지점의 바깥쪽에 장착되며 온도에 따라 갭을 폐쇄하거나 개방하는 씰을 포함하는 것을 기술적 특징으로 한다.
