Description

브레이크 보조 진공 장치Brake assisted vacuum device

본 발명은 브레이크 보조 진공 장치에 관한 것으로서, 상세하게는 엔진의 회전수와 브레이크 폐달의 작동 신호와 점화스위치의 신호를 논리 게이트에 의해 비교/판단하여 언덕길과 같은 오르막 길에서 자주 발생하는 브레이크 장치의 불안정을 해소하게 한 자동차의 브레이크 보조 진공 장치에 관한 것이다.[0001] The present invention relates to a brake assisted vacuum device, and more particularly to a brake assisted vacuum device for comparing and judging the revolution speed of an engine, an operation signal of a brake pedal and a signal of an ignition switch by a logic gate, Assisted vacuum device of an automobile which relieves instability.

본 발명이 적용되는 자동차의 브레이크 장치는 주행중 자동차를 감속하여 정지시키기 위한 장치의 총칭으로 대개 브레이크 폐달에 의해 운전자의 의지가 전달되는 조작력은 브레이크 마스터 실린더의 유압으로 변경되고 변경된 폐달의 압력은 부스터와 같은 유압 증폭장치를 통해 증폭되어 브레이크 라인을 따라 브레이크 라이닝에 압력을 가하여 제동 효과를 갖는 장치를 말하게 된다.The brake device of the vehicle to which the present invention is applied is a general term for a device for decelerating and stopping an automobile while driving. The operating force to which the driver's will is transmitted by the brake pedal is changed to the hydraulic pressure of the brake master cylinder. Refers to a device having a braking effect by being amplified through the same hydraulic amplifier and applying pressure to the brake lining along the brake line.

그러나, 상기와 같은 종래의 브레이크 장치는 브레이크 라인과 브레이크 라이닝에 작용되는 강한 유압에 의해 제동을 하게 됨에 따라 유압의 상승을 위해 작용되는 진공펌프가 작동하지 않을 경우 정상 유압이 상쇄 및 손실되어 제동력에 한계를 가지게 되며, 특히 언덕길과 같은 등판로에서 시동이 정지하게 되면 진공 펌프 모터의 동작이 중단되어 점차적으로 브레이크 폐달의 압력이 손실됨과 동시에 브레이크 폐달의 탄력이 상실되어 제동력을 잃게 되는 문제를 해소하지 못하였다.However, when the conventional brake apparatus is braked by the strong hydraulic pressure applied to the brake line and the brake lining, when the vacuum pump operated to raise the hydraulic pressure is not operated, the normal hydraulic pressure is canceled and lost, In particular, when the start of the engine is stopped in a backlit road such as a sloping road, the operation of the vacuum pump motor is interrupted so that the pressure of the brake pedal is gradually lost and the braking force is lost due to the loss of elasticity of the brake pedal I did not.

즉, 종래의 브레이크 장치는 시동이 중단된 상태에서 계속적인 제동을 하게 되면 유압의 손실을 진공 펌프 모터가 보충하지 못하여 제동력을 잃게되는 문제점이 있었다.That is, when the conventional braking device continuously brakes in the state where the starting is stopped, there is a problem that the vacuum pump motor fails to compensate for the loss of the hydraulic pressure and the braking force is lost.

이에, 본 발명은 상기와 같은 문제점을 해소하기 위하여 안출한 것으로서, 시동키의 온 신호와 브레이킹 작용시에 엔진의 RPM이 검출되지 않으면 진공 펌프 모터를 가동하여 브레이크 유압라인의 압력을 지속적으로 보충할 수 있게 하는 장치를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a brake system in which when the RPM of the engine is not detected at the ON signal of the ignition key and the braking action, The present invention has been made to solve the above problems.

따라서 본 발명의 장치는 시동키의 온 상태 신호(30)의 신호와 브레이크 폐달 스위치(20)의 신호와 엔진 RPM 신호(10)를 입력하여 진공 펌프 모터(40)의 작동 시기를 결정하는 논리 게이트의 조합과 신호를 제어하기 위한 릴레이(RY)가 구비되어 구성되는 것을 그 특징으로 한다.The apparatus of the present invention therefore includes a logic gate for inputting the signal of the on-state signal 30 of the ignition key, the signal of the brake damping switch 20 and the engine RPM signal 10 to determine the operation timing of the vacuum pump motor 40 And a relay (RY) for controlling the signal.

브레이크 폐달의 작동상태를 감지하는 브레이크 폐달 스위치(20)를 브레이크 폐달의 작동 연결부에 설치하고, 상기 브레이크 폐달 스위치(20)에 의해 브레이킹이 감지되면 온상태가 되는 신호와 시동키의 온 상태 신호(30)를 앤드 게이트1(AND1)에 입력하게 하고, 상기 앤드 게이트1(AND1)의 출력신호와 엔진 RPM의 펄스파에 대한 부정 신호를 입력하는 앤드 게이트2(AND2)를 설치하되, 상기 앤드 게이트2(AND2)의 출력신호를 트랜지스터를 통해 증폭하여 증폭된 신호가 릴레이(RY)를 작동하여 진공 펌프 모터(40)에 전원을 공급 함으로써 진공 펌프 모터(40)가 작동되어 브레이크 라인에 유압을 보충할 수 있게 설치 구성한다.A brake pedal depression switch 20 for detecting the operating state of the brake pedal is provided on the operating connection portion of the brake pedal. When the braking pedal depression switch 20 detects braking, (AND2) for inputting an AND gate 1 (AND1) and an output signal of the AND gate 1 (AND1) and a negative signal for a pulse wave of the engine RPM, 2 (AND2) is amplified through the transistor and the amplified signal is supplied to the vacuum pump motor 40 by operating the relay RY so that the vacuum pump motor 40 is operated to replenish the hydraulic pressure to the brake line To be installed.

상기한 본 발명의 구성에 대한 작용 및 효과는 다음과 같다.The functions and effects of the above-described configuration of the present invention are as follows.

시동키의 스위치 온 상태 신호는 시동키 박스의 시동키가 온 상태일 때만 온되어 신호를 앤드 게이트1(AND1)에 입력하는 작용을 하고, 동시에 브레이크 폐달 스위치(20)는 운전자에 의해 브레이크 폐달이 작동되면 온 상태가 되어 신호를 앤드 게이트1(AND1)의 타단에 입력하여 앤드 게이트1(AND1)이 시동키의 스위치가 온 상태에서 브레이크를 작동하고 있는지의 여부를 판별하여 판별된 신호를 앤드 게이트2(AND2)에 입력하게 되며, 동시에 앤드 게이트2(AND2)는 타단에 엔진 RPM의 펄스파에 대한 부정신호를 입력하여 엔진이 정지된 상태에서 앤드게이트1의 출력신호(시동키의 스위치가 온 상태에서 브레이크를 작동하고 있는지의 여부를 판별한 신호)와 비교/처리하여 엔진이 정지되고 시동 스위치가 온 상태이며 브레이크 폐달이 작동중이라는 신호를 출력하게 되는 작용을 하고, 출력된 신호는 트랜지스터에 의해 증폭되어 릴레이(RY)에 의해 전원을 진공 펌프 모터(40)에 공급하는 작용을 하여, 결과적으로 엔진이 정지되었지만 시동키가 온 상태에 있으므로 차량이 운행중이며 동시에 제동력이 필요한 시기에 진공 펌프 모터(40)가 작동 됨으로써 엔진정지 상태에서 브레이킹에 따른 브레이크 라인의 유압 손실을 보충하게 되는 작용을 한다.The switch-on state signal of the ignition key is turned on only when the ignition key of the ignition key box is in the ON state, and inputs a signal to the AND gate 1 (AND1). At the same time, the brake- When it is operated, it is turned on and a signal is inputted to the other end of the AND gate 1 (AND1) to determine whether or not the AND gate 1 (AND1) is operating the brake while the switch of the starter key is on, 2 (AND2). At the same time, the AND gate 2 (AND2) inputs the negative signal for the pulse wave of the engine RPM to the other end and outputs the output signal of the AND gate 1 (I.e., a signal that determines whether or not the brake is operated in the state), and outputs a signal indicating that the engine is stopped and the ignition switch is on and the brake pedal is in operation The output signal is amplified by the transistor and supplied to the vacuum pump motor 40 by the relay RY. As a result, since the engine is stopped but the starter key is in an ON state, The vacuum pump motor 40 is operated at the same time when the braking force is required while the vehicle is in operation, thereby compensating for the hydraulic loss of the brake line due to braking in the engine stop state.

따라서, 본 발명의 브레이크 진공 보조장치를 이용한 차량은 주행중 언덕길과 같은 오르막길에서 발생되는 엔진 정지현상에 따른 브레이크 라인의 유압이 손실문제를 본 발명의 보조 진공장치가 진공 펌프 모터를 동작하여 제동력을 지속시켜 줌으로서 안전을 보장하게 하는 이점이 있다.Therefore, when the auxiliary vacuum device of the present invention operates the vacuum pump motor to sustain the braking force, the hydraulic pressure loss of the brake line due to the engine stoppage phenomenon occurring in an uphill road such as a downhill road during the running of the vehicle is prevented. Thereby ensuring safety.
