Abstract

본 발명은 자동차의 동력조향(Power Steering) 장치에 있어서 토션바의 비틀림력을 주행속도에 따라서 자동조절되게 하므로서 조향휠의 조작력을 향상시켜 안전운전에 이바지 할 수 있도록 한 동력조향장치의 토션바의 비틀림 응력 조절장치에 관한 것이다.According to the present invention, the torsion bar of the power steering device of the power steering device can improve the operating force of the steering wheel by automatically adjusting the torsional force of the torsion bar according to the traveling speed in the power steering device of the automobile. It relates to a torsional stress control device.

본 발명은 기존의 스티어링하우징에 장착된 토션바와 로타리밸브 사이의 유압실 직상방에 실린더실을 마련하고, 상기 유압실과 실린더실 사이를 스프링으로 탄력지지되는 피스톤을 장착하여 저속 주행시에는 센 리턴유압이 피스톤을 상승이동시켜 실린더실에 위치하는 토션바의 상단 부분까지 리턴유압이 작용하도록 하는 방법으로 조향월의 조작력을 가볍게 할 수 있도록 하고, 고속주행시에는 약한 러턴유압이 실린더실 내부로 유입되어 피스톤이 하강하여 토션바의 유효 비틀림 길이가 짧아지게 하므로서 조향휠의 조작력을 무겁게 하여 주행속도에 따라서 조향휠의 조작력을 향상시킬 수 있도록 함고 아울러서 고속주행시 조향휠의 조작에 안정감을 향상시킬 수 있도록 한 것이다.The present invention provides a cylinder chamber directly above the hydraulic chamber between the torsion bar and the rotary valve mounted on the existing steering housing, and is equipped with a piston that is elastically supported by a spring between the hydraulic chamber and the cylinder chamber, the high return hydraulic pressure during low-speed running By moving the piston upward, the return hydraulic pressure is applied to the upper part of the torsion bar located in the cylinder chamber, so that the steering force of the steering wall can be lightened.In high-speed driving, the weak luton hydraulic pressure flows into the cylinder chamber and the piston By lowering the effective torsion length of the torsion bar, the steering wheel weight is increased so that the steering wheel can be improved according to the driving speed, and the stability of steering wheel can be improved when driving at high speed.
