Description

자동차용 유압시스템의 비례제어 밸브Proportional control valve of automotive hydraulic system

본 고안은 자동차 유압시스템의 비례제어밸브에 관한 것으로서 더욱 상세하게는 비례제어밸브의 작동성 및 소음의 발생을 방지하기 위한 완충재를 이용한 고안이다.The present invention relates to a proportional control valve of an automobile hydraulic system, and more particularly, a design using a cushioning material for preventing the operation and noise of the proportional control valve.

자동차의 비례제어밸브는 유압시스템에서 마스터실린더와 휠실린더사이의 압력을 제어 조정하여 후륜의 제동력을 제어하는 것으로서,The proportional control valve of the vehicle controls the braking force of the rear wheel by controlling and adjusting the pressure between the master cylinder and the wheel cylinder in the hydraulic system.

자동차의 브레이크작동시 전륜측과 후륜측에 작용하는 하중이 다르기 때문에 자동차 제동장치에서 마스터실린더의 압력을 제어함으로서 후륜으로의 압력이 직접전달됨으로 인해 우려되는 고착현상을 미연에 방지할 수 있다.Since the load acting on the front wheel and the rear wheel during brake operation of the car is different, the control of the pressure of the master cylinder in the automobile braking device can prevent the sticking phenomenon caused by the direct transfer of the pressure to the rear wheel.

즉 상기의 목적을 위해 전륜에 가해지는 제동압력에 일정비율만큼 비례하여 후륜제동압력을 제어할 수 있는 부재로서 관상하우징체의 비례제어밸브(10)를 유압계에 채택하고 있다.That is, for the above purpose, the proportional control valve 10 of the tubular housing is adopted in the hydraulic system as a member capable of controlling the rear wheel braking pressure in proportion to the braking pressure applied to the front wheel by a certain ratio.

이러한 종래의 자동차 유압시스템의 비례제어밸브(10)는 유체관로에 장착되는 파이프 형상의 하우징(4,5)내에 수납되는 다수의 제어부제로서 구성되며,The proportional control valve 10 of the conventional hydraulic system of the vehicle is configured as a plurality of control units accommodated in the pipe-shaped housing (4, 5) to be mounted to the fluid pipeline,

상기 자동차 유압시스템의 비례제어밸브(10)는 내방측 중심에 제어용 유로를 구비하는 제어피스톤(2)을 가지게 되고, 이 제어피스톤(2)은 운전자가 제동후 패달을 해제시, 입구측으로 진행된 제어피스톤(2)이 전륜측에 일정 압력이 형성된 후 출구측으로 복귀하게 되는 과정에서 스프링(6)의 탄성력의 증대에 의하여 제어피스톤(2)의 스프링지지단(11)과 출구측에 형성된 아웃렛하우징(5)의 접촉단부(12)의 접촉으로 인한 접촉소음이 발생된다.The proportional control valve 10 of the hydraulic system of the vehicle has a control piston 2 having a control flow path at the center of the inward side, and the control piston 2 has a control that proceeds to the inlet side when the driver releases the pedal after braking. Outlet housings formed on the spring support end 11 and the outlet side of the control piston 2 by increasing the elastic force of the spring 6 in the process of returning to the outlet side after the piston 2 is formed with a predetermined pressure on the front wheel side ( Contact noise is generated due to the contact of the contact end 12 of 5).

상기의 접촉으로 인한 충격은 비례제어밸브 전체의 내구성 저하로 인한 제품의 작동 불량을 일으킬 수도 있으며, 소음은 운전자의 쾌적한 운전환경을 저해하는 요소가 되기도 한다.The impact due to the above contact may cause a malfunction of the product due to the deterioration of the durability of the proportional control valve as a whole, and the noise may be a factor that hinders the driver's pleasant driving environment.

본 고안은 상기에서 발생하는 문제점을 해결하기 위해 자동차용 비레제어밸브(10)의 제어피스톤(2)의 선단부(14)와 아웃렛하우징(5)의 접촉단부(12) 상간에 완충제(3)를 형성함으로서 브레이크 작동시 소음 발생 및 제품의 내구성의 향상을 이루고자 한다.The present invention provides a buffer (3) between the top end portion 14 of the control piston (2) and the contact end portion 12 of the outlet housing (5) of the vehicle control valve (10) to solve the problems occurring above. By forming the brakes to achieve noise and improve the durability of the product.
