Description

자동차의 흡기다기관 개페식 엔진브레이크 장치Engine intake manifolds of automobiles

본 발명은 자동차의 흡기다기관 개폐식 엔진브레이크 장치에 관한 것으로, 더욱 상세하게는 급제동시 흡기다기관에 설치된 개페밸브를 폐쇄시키어 연소실로 공급되는 공기를 순간적으로 감소시키게 하므로써 엔진 출력의 감소에 의해 제동력이 향상되는 자동차의 흡기다기관 개폐식 엔진브레이크 장치에 관한 것이다.The present invention relates to an intake manifold engine brake device of an automobile. More particularly, the braking force is improved by reducing the engine output by closing the open / close valve installed in the intake manifold during instant braking to temporarily reduce the air supplied to the combustion chamber. It relates to an intake manifold retractable engine brake device of a vehicle.

일반적으로 자동차에는 차량을 감속하여 정지시키기 위한 제동목적의 브레이크 장치가 사용되고 있는 바, 용도별로는 주행중에 운전자의 발로 조작하는 주 브레이크(일명 풋 브레이크)와, 손으로 조작하여 자동차를 주차상태로 유지하기 위한 주차 브레이크(일명 핸드 브레이크)가 있다.In general, a brake device for braking purpose is used in a car to decelerate and stop the vehicle. For each use, a main brake (aka foot brake) operated by the driver's foot while driving and a vehicle operated by hand to keep the vehicle parked There is a parking brake (aka hand brake).

또한 엔진의 압축압력을 이용하여 제동력을 얻도록 한 엔진브레이크나, 4사이클 디젤 엔진을 채용한 대형차에 이용되는 배기브레이크와 같은 보조 브레이크도 있음은 주지의 사실이다.It is also well known that there are also auxiliary brakes, such as an engine brake to obtain a braking force by using the compression pressure of the engine, and an exhaust brake used in a large vehicle employing a four-cycle diesel engine.

상기한 브레이크 장치들은 주행중인 자동차를 급제동하거나 특히 강우나 강설에 의해 미끄러운 노면에서 급제동을 하게 되면 차륜이 미끄러지는 슬립상태가 되면서 차륜이 로크되어 조향을 하더라도 운전자가 의도하는 방향으로 자동차를 진행시키지 못하게 되어 사고의 위험이 높아지게 되는 바, 현재에는 이러한 슬립을 방지하기 위해 급제동시 바퀴가 로크되지 않도록 한 ABS(anilock brake system)가 많이 보급되고 있는 실정이다.The brake devices are designed to prevent the vehicle from moving in the direction intended by the driver even when the vehicle is locked and steered when the vehicle is locked by a sudden braking of the driving vehicle or a braking surface on a slippery road due to rain or snow. As the risk of an accident increases, the current situation is that ABS (anilock brake system) is widely used to prevent the wheels from locking during sudden braking to prevent such slip.

ABS는 주 브레이크와 연계되어 있어서 주 브레이크 작동시 초당 10여회이상의 더블 브레이크를 밟는 효과를 내어 제동력이 크게 향상되고, 상기에서와 같이 차륜을 로크하지 않기 때문에 급제동시 조향도 가능하게 되어 있어서 안전성능이 보다 향상되는 잇점을 갖추게 된다.ABS is connected with the main brake, which makes the double brake more than 10 times per second during the main brake, greatly improving the braking force, and as the wheel is not locked as described above, steering is also possible during sudden braking. You have the benefit of being better.

현재의 자동차들은 고출력화를 추구하면서도 반면에 안전운전을 위해 출력을 제어할 수 있는 브레이크 시스템도 함께 개발하고 있는 바, 급정지시나 급회전시 제동력의 향상은 안전운행과 직결된다.Cars are currently developing high-powered brake systems, while developing brake systems that can control the output for safe driving. Therefore, the improvement of braking force during sudden stops or sharp turns is directly related to safe driving.

그러나, 종래의 브레이크 장치는 차륜에 브레이크 패드 등으로 마찰을 일으켜 제동케 하는 것이므로 급제동시 빗길이나 눈길에서는 미끄러지기 때문에 확실한 제동력 확보가 어렵게 되어 있고, ABS가 장치되지 않은 차량의 초보운전자는 급제동시 당황하여 더블브레이크작동을 미처 못하게 되는 경우와 더불어 제동력 증가를 위한 별도의 엔진 브레이크조작도 미숙하여 주 브레이크의 무리한 답력공급으로 브레이크 패드의 과도한 손상이 생기는 문제가 있다.However, the conventional brake device causes friction to brake the brake pads, etc., so that it is difficult to secure a firm braking force because it slips on rain or snow during sudden braking, and novice drivers of vehicles without ABS are embarrassed when braking. In addition, there is a problem that excessive damage to the brake pads occurs due to excessive power supply of the main brake due to immature double brake operation and additional engine brake operation for increasing braking force.

따라서, 본 발명은 상기한 종래의 문제를 해결하기 위하여 발명된 것으로, 브레이크 페달에 급격한 답력공급에 의한 ABS 작동시 엔진의 흡기다기관에 유입 공기제어를 위한 개폐밸브를 순간적으로 닫아 주므로써 엔진출력 감소로 제동력이 크게 향상되도록 한 자동차의 흡기다기관 개폐식 엔진브레이크 장치를 제공함에 발명의 목적이 있다.Accordingly, the present invention has been invented to solve the above-described problems, and by reducing the engine output by closing the on-off valve for controlling the intake air to the intake manifold of the engine momentarily during the ABS operation by supplying a sudden stepping force to the brake pedal It is an object of the present invention to provide an intake manifold open / close engine brake device for a vehicle in which a low braking force is greatly improved.

싱기와 같은 목적을 실현하기 위한 본 발명은 브레이크 페달의 답력과 차속을 판단하여 ABS 액튜에이터를 구동시키는 ABS제어유닛의 출력단에 밸브제어 유닛이 연결되는 한편, 상기 밸브제어유닛의 출력단에는 흡기다기관의 입구에 신설된 개폐밸브를 작동토록 한 밸브액튜에이터가 연결된 것이다.According to the present invention for realizing the same purpose as a singing machine, a valve control unit is connected to an output end of an ABS control unit for driving an ABS actuator by determining a pedaling force and a vehicle speed of a brake pedal, while an inlet of an intake manifold is connected to an output end of the valve control unit. The valve actuator for operating the on-off valve established in the is connected.

따라서, 본 발명은 고속주행중인 차량이 브레이크 페달한 급격한 답력이 공급되어지면, ABS제어유닛이 ABS액튜에이터를 작동시킴과 더불어 백브제어유닛으로 밸브작동신호를 출력하여 상기 밸브제어유닛이 밸브액튜에이터를 제어토록 하고, 이에 흡기다기관의 입구는 개폐밸브로 하여 순간적으로 폐쇄되므로 흡입공기의 감소에 의해 엔진출력이 저감되게 하는 것으로, 급제동시 ABS 작동과 더불어 엔진출력의 저하로 보다 확실한 제동과 작동이 이루어지도록 되어 있다.Therefore, in the present invention, when the rapid driving force of the brake pedal is supplied to a vehicle in high-speed driving, the ABS control unit operates the ABS actuator and outputs the valve operation signal to the back control unit so that the valve control unit controls the valve actuator. In this case, the inlet of the intake manifold is closed by an on-off valve to instantly reduce the engine power by reducing the intake air. It is.

본 발명은 브레이크페달(10)의 답력에 의하여 감속되는 차량의 속도를 감지하는 차속센서(12)가 ABS액튜에이터(14)를 구동시키는 ABS 제어유닛(16)에 연결되고, 이 ABS제어유닛(16)에는 흡기다기관(20)의 입구(22)에 설치된 개폐밸브(24)를 작동시키는 밸브액튜에이터(26)가 연결되어 이루어진 자동차의 흡기다기관 개폐식 엔진브레이크 장치이다.The present invention is connected to the ABS control unit 16 for driving the ABS actuator 14, the vehicle speed sensor 12 for detecting the speed of the vehicle decelerated by the pedal pedal 10, the ABS control unit 16 ) Is an intake manifold open / close engine brake device for a vehicle in which a valve actuator 26 for operating an on / off valve 24 installed at an inlet 22 of the intake manifold 20 is connected.

예시도면 제1도는 본 발명에 따른 엔지브레이크 장치의 구성도면이다.Exemplary Drawing 1 is a block diagram of an engine brake apparatus according to the present invention.

여기서, 본 발명은 운전자의 급제동시 공지의 ABS시스템이 작동됨과 더불어 흡기다기관(20)쪽으로 유입공기를 차단기켜주므로 엔진출력의 감소로 보다 나은 제동효과를 갖도록 이루어진 것으로, ABS제어유닛(16)의 입력단에는 브레이크 페달(10)에 의하여 감속되는 차속을 감지하는 차속센서(12)가 연결되어 있으며, 그 출력단에는 ABS액튜에이터(14)가 연결되어 있다.Here, the present invention is made to have a better braking effect by reducing the engine output since the known ABS system is operated at the time of sudden braking of the driver and the inlet air is cut off toward the intake manifold 20. A vehicle speed sensor 12 for detecting a vehicle speed decelerated by the brake pedal 10 is connected to an input terminal, and an ABS actuator 14 is connected to the output terminal thereof.

따라서, 고속주행시 브레이크페달(10)에 답력이 가해지면, 공지의 방식에 의해 ABS제어유닛(16)은 ABS액튜에이터(14)를 통전제어하여 차륜에 ABS의 제동력을 가하게 된다.Therefore, when the pedaling force is applied to the brake pedal 10 during high-speed driving, the ABS control unit 16 energizes and controls the ABS actuator 14 by a known method to apply the braking force of the ABS to the wheels.

이에 더불어 본 발명은 엔진의 각 실린더의 연소실마다 공기를 공급하도록 된 흡기다기관(20)의 입구(22)를 개폐토록 하는 개폐밸브(24)가 장착되어 있는바, 상기 개폐밸브(24)의 작동은 밸브제어유닛(18)의 신호에 따라 밸브액튜에터(26)가 작동하여 이루어지되, 이 밸브제어유닛(18)은 ABS제어유닛(16)이 밸브작동 신호를 출력하게 되면 작동하도록 되어 있다.In addition, the present invention is equipped with an on-off valve 24 for opening and closing the inlet 22 of the intake manifold 20 to supply air to each combustion chamber of each cylinder of the engine, the operation of the on-off valve 24 The valve actuator 26 is operated according to the signal of the valve control unit 18. The valve control unit 18 is operated when the ABS control unit 16 outputs the valve operation signal. .

따라서, 본 발명은 고속주행시 운전자가 브레이크페달(10)을 밟아주게 되면, 감속된 차량속도를 차속센서(12)가 감지하여 이의 신호를 ABS제어유닛(16)에 인가시키게 되고, 이 ABS액튜에이터(14)는 밸브제어유닛(18)에 신호를 인가시키게 된다. 그러면, 상기한 신호를 입력받은 밸브제어유닛(18)은 밸브액튜에이터(26)를 통전제어하여 흡기다기관(20)의 입구(22)를 신속하게 폐쇄시키어 실린더의 연소실로의 공기유입을 차단케 하므로 엔진의 출력이 저하된다.Therefore, in the present invention, when the driver steps on the brake pedal 10 during high-speed driving, the vehicle speed sensor 12 detects the decelerated vehicle speed and applies a signal thereof to the ABS control unit 16, and the ABS actuator ( 14 applies a signal to the valve control unit 18. Then, the valve control unit 18 receiving the above-mentioned signal energizes and controls the valve actuator 26 to close the inlet 22 of the intake manifold 20 to block the inflow of air into the combustion chamber of the cylinder. The output of the engine is lowered.

상기한 바와 같이, 본 발명은 고속주행중인 차량의 운전자가 브레이크페달의 밟는 답력에 의하여, ABS제어유닛이 ABS액튜에이터를 작동시킴과 더불어 밸브 제어유닛으로 밸브작동신호를 출력하여 상기 밸브제어유닛이 밸브액튜에이터를 제어토록 하고, 이에 흡기다기관의 입구는 개폐밸브를 이용하여 신속하게 폐쇄시킴에 따라 흡입공기의 감소에 의해 엔진출력이 저감되는 것으로, 급제동시 ABS작동과 함께 엔진출력감소에 의해 보다 확실한 제동과 작동이 이루어지는 효과가 있다.As described above, according to the present invention, the ABS control unit operates the ABS actuator and outputs the valve operation signal to the valve control unit according to the stepping force of the brake pedal by the driver of the vehicle driving at a high speed, thereby allowing the valve control unit to operate the valve.
