Noise characteristics on the camring profile of the hydraulic vane pump in the power steering system

파워 스티어링용 유압 베인 펌프의 캠링 형상에 따른 소음특성

Recently, according as the supply of power steering system has been diffused, for the comfortable driving condition, the problem to reduce the noise and vibration of this system suddenly appeared. This system can be classified two systems of the pipe line and the pump. In this paper, it is described about the noise characteristic with the camring profile of the hydraulic vane pump. As a result, when it excesses tolerance, the noise is increased. Moreover, in the case of the same of cam-ring, the effect of the rotating speed is larger than the discharge pressure.
