Description
본 고안은 부트시일에 관한 것으로, 특히 부트시일의 주름부가 고속회전시 팽창되는 것을 억제하여 구리스의 누출을 방지함으로써 내구신뢰성을 향상시킬 수 있도록 된 등속조인트용 부트시일의 설치구조에 관한 것이다.The present invention relates to a boot seal, and more particularly, to an installation structure of a boot seal for a constant velocity joint, which is capable of improving durability by preventing leakage of grease by expanding the corrugated portion of the boot seal at high speed rotation.
일반적으로 부트시일(BOOT SEAL)은, 동력전달장치의 구동축에 쓰이는 등속조인트(Constant Velocity Joint)와, 브레이크페달의 밟는 힘을 유압으로 전환하는 매스터실린더(Master Cylinder)와, 유압식드럼브레이크에서 매스터실린더로부터 유압에 따라 브레이크 슈를 드럼에 압착시키는 역할을 하는 휠 실린더(Wheel Cylinder) 및, 케이블과, 전선 또는 커넥터등 임의의 부분을 보호하기 위해서 씌우는 고무이다.In general, BOOT SEAL is a constant velocity joint used for the drive shaft of a power train, a master cylinder that converts the stepping force of the brake pedal into a hydraulic cylinder, and a master cylinder in a hydraulic drum brake. It is a rubber that is covered to protect any part such as a wheel cylinder and a cable, an electric wire or a connector that serves to press the brake shoe to the drum according to the hydraulic pressure from the drum.
여기서 상기 등속조인트에 부트시일이 체결되는 구조는 도 1에 도시된 것과 같이, 등속조인트의 외륜(10)에 형성된 원주홈(11)과 외륜(10)의 직경보다 작은 직경의 축(20)에 형성된 원주흠(21)에 부트시일(30)의 양쪽단이 끼워적 클램프 (40,50)로 조입으로써 체결되는 한편, 상기 부트시일(30)의 내부에는 구리스(60)가 채워진 구조로 되어 있다.Here, the structure in which the boot seal is fastened to the constant velocity joint is as shown in FIG. 1, in the shaft 20 having a diameter smaller than the diameter of the circumferential groove 11 and the outer ring 10 formed in the outer ring 10 of the constant velocity joint. Both ends of the boot seal 30 are fastened by inserting clamps 40 and 50 to the formed circumferential flaws 21, while grease 60 is filled in the boot seal 30. .
상기 부트시일(30)은, 상기 외륜(10)에 형성된 원주홈(11)을 지나쳐서 배치 되도록 끼워짐과 더불어 클램프(40)로 체결되는 외륜끼움부(31)와, 상기 축(20)에 형성된 원주홈(21)을 지나쳐서 배치되도록 끼워짐과 더불어 클램프(50)로 체결되는 축끼움부(32) 및, 상기 외륜끼움부(31)와 축끼움부(32)가 일체로 연결되도록 다수 개의 주름진 형상으로 이루어진 주름부(33)로 이루어져 있다.The boot seal 30 is fitted to be disposed so as to pass past the circumferential groove 11 formed in the outer ring 10, and is formed on the shaft 20 and the outer ring fitting portion 31 fastened by the clamp 40. A plurality of corrugations are fitted so as to pass past the circumferential groove 21 and coupled to the shaft fitting portion 32 fastened by the clamp 50, and the outer ring fitting portion 31 and the shaft fitting portion 32 are integrally connected to each other. It consists of wrinkles 33 made in the shape.
따라서 상기 부트시일(30)의 내부에 채워진 구리스(60)가 외륜(10)과 축(20) 의 유동시 발생되는 마모를 방지하게 된다.Therefore, the grease 60 filled in the boot seal 30 prevents abrasion generated when the outer ring 10 and the shaft 20 flow.
그러나 이러한 등속조인트용 부트시일의 설치구조는, 고속회전시 주름부가 팽창하여 쉽게 변형이 되어 구리스의 누출이 발생됨은 물론 부트시일의 바깥쪽을 설계시 설계자유도가 나쁜 결점이 있었다.However, the installation structure of the boot seal for the constant velocity joint has a defect in design freedom when designing the outside of the boot seal as well as the leakage of grease due to expansion of the crease at high speed rotation.
이에 본 고안은 상기와 같은 결점을 해결하기 위해 안출된 것으로, 부트시일의 주름부내부에 형성된 골에서부터 돌출된 오일립이 축의 오일립밀착홈에 밀착됨과 더불어 이 오일립이 스프링밴드에 의해 밀착력이 강화되도록 되어, 부트시일의 주름부가 고속회전시 팽창되는 것을 억제하여 구리스의 누출을 방지함으로써 내구 신뢰성을 향상시킬 수 있도록 된 등속조인트용 부트시일의 설치구조를 제공함에 그 목적이 있다.The present invention has been devised to solve the above drawbacks, the oil lip protruding from the bone formed in the inner portion of the boot seal is in close contact with the oil lip contact groove of the shaft and the oil lip is in close contact with the spring band. The purpose of the present invention is to provide an installation structure of a boot seal for a constant velocity joint that can be strengthened, thereby preventing expansion of the corrugated portion of the boot seal at high speed to prevent leakage of grease, thereby improving durability.
