본 발명은 차량용 등속조인트에 관한 것으로, 더욱 상세하게는 단렬로 구성되던 볼을 복렬로 배치하여 구성함으로써 고하중 전달에 유리한 차량용 등속조인트에 관한 것이다.The present invention relates to a constant velocity joint for a vehicle, and more particularly, to a constant velocity joint for a vehicle, which is advantageous for high load transmission by arranging balls arranged in a row in a double row.

일반적으로 등속조인트는 전륜구동형 자동차의 드라이브 샤프트에 적용되는 부품으로, 전륜 조향에 의해 동력이 전달되는 각도가 변하더라도 회전 불균형이 발생하지 않고 신속하게 전륜을 구동할 수 있도록 해주는 역할을 한다.In general, the constant velocity joint is a component that is applied to the drive shaft of a front wheel drive type vehicle, and serves to enable the front wheel to be driven quickly without rotation imbalance even if the angle of power transmission is changed by the front wheel steering.

이러한 목적으로 사용되는 등속조인트는 드라이브 샤프트를 중심으로 휠(Wheel) 측에 장착되는 버필드조인트(Birfield Joint)와 트랜스미션(T/M) 측에 장착되는 트리플조인트(Triple Joint) 및 드라이브 샤프트(Drive shaft), 부트(boot) 등을 포함하여 구성된다.The constant velocity joints used for this purpose are the Burfield Joint mounted on the wheel side around the drive shaft, and the Triple Joint and Drive shaft mounted on the Transmission (T / M) side. shaft, boot, etc.
