Abstract

본 발명은 차속감응형 동력조향장치의 마찰력 조절장치에 관한 것으로, 종래에는 차량의 속도에 따라 유압펌프의 작동압력을 제어하여 작동압의 양을 조절하므로써 핸들의 무게를 제어하는 것으로 저속주행시 작동압이 높아 핸들의 복원성이 떨어지는 문제가 발생하는 등 유체에 의해 발생되는 작동압의 비선형적인 특성으로 저속영역과 고속영역에서 동시에 만족할 수 있도록 조절하는데 어려움이 있었다.[0001] The present invention relates to an apparatus for adjusting the friction force of a vehicle speed-sensitive power steering apparatus, and more particularly to a system and method for controlling the operating force of a hydraulic pump And there is a problem that the stability of the handle is deteriorated. Therefore, it has been difficult to control the operating pressure to be satisfied simultaneously in the low speed region and the high speed region due to the nonlinear characteristics of the operating pressure generated by the fluid.

본 발명은 예시도면 제3도와 같이, 조향축(16)의 일단에 경사면(24)을 갖는 마찰수단(18)이 설치되고, 상기 마찰수단(18)의 상면에 구동수단(20)에 의해 구동되는 압박수단(22)이 설치되며, 차속에 따라 상기 구동수단(20)을 제어할 수 있는 ECU(14)가 상기 구동수단(20)에 연결되어 이루어진 것이다.The present invention is characterized in that a rubbing means 18 having an inclined surface 24 is provided at one end of a steering shaft 16 and a driving means 20 is provided on the upper surface of the rubbing means 18, And an ECU 14 capable of controlling the driving means 20 is connected to the driving means 20 in accordance with the vehicle speed.

따라서, 본 발명에 따르면 유압펌프의 작동력을 변화시키기 위해 복잡한 장치를 구비하는 대신 경사면을 이용한 간단한 장치로 차량의 속도에 따라 핸들의 무게를 제어할 수 있어 차속감응형 동력조향장치의 단순화 및 실용화를 앞당길 수 있는 유용한 것이다.Therefore, according to the present invention, it is possible to control the weight of the steering wheel according to the speed of the vehicle by using a simple device using an inclined surface instead of a complicated device for changing the operating force of the hydraulic pump, thereby simplifying and realizing the vehicle speed sensitive type power steering It is useful to be able to advance.
