Description
Claims (4)
- 외주면에는 나선형의 외부홈이 형성된 나사축, 상기 나사축의 외부에 설치되며 내주면에는 상기 외부홈과 대응되는 내부홈이 형성된 너트, 상기 외부홈과 내부홈에 대응되도록 외주연에 나선형으로 배치된 다수개의 지지홀이 형성된 볼부시와, 상기 지지홀에 삽입되는 다수개의 볼을 구비한 볼스크류장치에 있어서,상기 볼부시에는 상기 볼의 이탈을 방지할 수 있도록 상기 지지홀의 내, 외측으로 돌출되어 상기 볼의 일부를 감싸는 탄성지지부가 일체로 형성된 것을 특징으로 하는 볼스크류장치.
- 제 1항에 있어서,상기 볼부시는 제작이 용이하고 소음이 저감되도록 플라스틱재질로 사출 성형되어 상기 지지홀과 탄성지지부가 일체로 마련되는 것을 특징으로 하는 볼스크류장치.
- 제 2항에 있어서,상기 너트의 축방향 양측단에는 상기 볼부시의 축방향 이동을 제한할 수 있도록 스톱퍼와셔가 마련된 것을 특징으로 하는 볼스크류장치.
- 제 3항에 있어서,상기 나사축은 모터의 구동력으로 랙바를 축방향 이동시킬 수 있도록 마련된 랙 구동식 전동 파워스티어링 시스템(R-EPS : RACK ASSIST TYPE - ELECTRIC POWER STEERING SYSTEM)의 랙바에 설치되고, 상기 너트는 상기 모터에 의해 회전 가능하도록 상기 나사축의 외부에 설치되며, 상기 볼부시는 상기 지지홀의 내부에 상기 볼을 삽입하여 상기 너트와 나사축의 사이에 설치되며, 상기 스톱퍼와셔는 상기 볼부시의 양단에 설치된 것을 특징으로 하는 볼스크류장치.
