Description

자동차의 흡기다기관 개폐식 엔진브레이크 장치Air intake manifold retractable engine brake

본 발명은 자동차의 흡기다기관 개폐식 엔진브레이크 장치에 관한 것으로, 더욱 상세하게는 급제동시 흡기다기관에 설치된 개폐밸브를 닫아주어 연소실로 공급되는 공기를 순간적으로 감소되게 하므로 엔진 출력의 감소에 의해 제동력이 향상되게 한 자동차의 흡기다기관 개폐식 엔진브레이크 장치에 관한 것이다.The present invention relates to an intake manifold engine brake device of an automobile, and more particularly, closes the on / off valve installed in the intake manifold during rapid braking, thereby temporarily reducing the air supplied to the combustion chamber, thereby improving braking force by reducing the engine output. It relates to an intake manifold retractable engine brake device of a motor vehicle.

일반적으로 자동차에는 차량을 감속하여 정지시키기 위한 제동목적의 브레이크 장치가 사용하고 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 for a vehicle to decelerate and stop the vehicle. For each use, a main brake (aka foot brake) that is operated by the driver's foot while driving, and the vehicle is parked by hand There is a parking brake (aka hand brake) for holding.

또한 엔진의 압축압력을 이용하여 제동력을 얻도록 한 엔진브레이크나, 4사이클 디젤 엔진을 채용한 대형차에 이용되는 배기브레이크와 같은 보조 브레이크도 있음은 주지된 사실이다.It is also well known that there are also auxiliary brakes such as engine brakes that use the compression pressure of the engine to obtain braking force, and exhaust brakes used in large vehicles 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(antilock brack 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 (antilock brack system), which prevents the wheel from locking during sudden braking, is widely used to prevent such slip.

ABS는 주 브레이크와 연계되어 있어서 주 브레이크 작동시 초당 10여회 이상의 더블 브레이크를 밟는 효과를 내어 제동력이 크게 향상되고, 상기에서와 같이 차륜을 로크하지 않기 때문에 급제동시 조향도 가능하게 되어 있어서 안전성능이 보다 향상되게 한다.ABS is connected to the main brake, which makes the double brake more than 10 times per second during main brake operation, greatly improving the braking force, and does not lock the wheel as described above. To improve.

현재의 자동차들은 고출력화를 추구하면서도 반면에 안전운전을 위해 출력을 제어할 수 있는 브레이크 시스템도 함께 개발하고 있는 바, 급정거시나 급회전시 제동력의 향상은 안전운행과 직결된다.Cars are currently developing high-power cars, 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 패드등으로 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 slides 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 안출된 것으로, 브레이크 페달에 급격한 답력공급에 의한 ABS 작동시 엔진의 흡기다기관에 유입공기 제어를 위한 개폐밸브를 순간적으로 닫아주므로서 엔진출력 감소로 제동력이 크게 향상되도록 한 자동차의 흡기다기관 개폐식 엔진브레이크 장치를 제공하고자 함에 발명의 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and by reducing the engine output by closing the on-off valve for controlling the inlet air to the intake manifold of the engine momentarily during 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 to greatly improve the braking force.

상기와 같은 목적을 실현하기 위한 본 발명은 브레이크 페달의 답력과 차속을 판단하여 ABS 엑튜에이터를 구동시키는 ABS 제어유닛의 출력단에 밸브 제어유닛이 연결되는 한편, 상기 밸브 제어유닛의 출력단에는 흡기다기관의 입구에 신설된 개폐밸브를 작동토록 한 밸브 엑튜에이터가 연결된 것이다.The present invention for achieving the above object is a valve control unit is connected to the output end of the ABS control unit for driving the ABS actuator by determining the pedal force and the vehicle speed of the brake pedal, while the output end of the valve control unit of the intake manifold The valve actuator is connected to the on-off valve.

따라서, 본 발명은 고속주행중인 차량이 브레이크 페달에 급격한 답력이 공급되어지면, ABS 제어유닛이 ABS 엑튜에이터를 작동시킴과 더불어 밸브 제어유닛으로 밸브작동신호를 출력하여 상기 밸브 제어유닛이 밸브 엑튜에이터를 제어토록 하고, 이에 흡기다기관의 입구는 개폐밸브로 하여 순간적으로 폐쇄되므로 흡입공기의 감소에 의해 엔진출력이 저감되게 하는 것으로, 급제동시 ABS 작동과 더불어 엔진출력의 저하로 보다 확실한 제동효과와 작동의 편리를 얻고자 하는 것이다.Therefore, in the present invention, when a fast driving vehicle is supplied with a rapid pedal force to the brake pedal, the ABS control unit operates the ABS actuator and outputs a valve operation signal to the valve control unit so that the valve control unit is a valve actuator. In this case, the inlet of the intake manifold is closed by the on / off valve, and the engine output is reduced by reducing the intake air. To get the convenience of.

본 발명의 구성 및 작용 효과를 첨부된 예시도면에 의거하여 상세히 설명하면 다음과 같다.Referring to the configuration and operation of the present invention in detail based on the accompanying drawings as follows.

본 발명은 브레이크 페달(10)의 답력과 차속센서(12)로 감지된 신호를 판단하여 ABS 엑튜에이터(14)를 구동시키는 ABS 제어유닛(16)의 출력단에 밸브 제어유닛(18)이 연결되는 한편, 상기 밸브 제어유닛(18)의 출력단에는 흡기다기관(20)의 입구(22)에 신설된 개폐밸브(24)를 작동토록 한 밸브 엑튜에이터(26)가 연결된 자동차의 흡기다기관 개폐식 엔진브레이크 장치이다.According to the present invention, the valve control unit 18 is connected to the output terminal of the ABS control unit 16 which drives the ABS actuator 14 by judging the pedal force of the brake pedal 10 and the signal detected by the vehicle speed sensor 12. On the other hand, the intake manifold open / close engine brake device of the vehicle to which the valve actuator 26 for operating the on-off valve 24 newly established at the inlet 22 of the intake manifold 20 is connected to the output end of the valve control unit 18. to be.

예시도면 도 1은 본 발명에 따른 엔진브레이크 장치의 구성도면이다.Exemplary Drawings Figure 1 is a block diagram of an engine brake apparatus according to the present invention.

여기서, 본 발명은 운전자의 급제동시 ABS 시스템이 작동됨과 더불어 흡기다기관의 유입공기를 차단시켜주므로 엔진출력의 감소로 보다 나은 제동효과를 갖도록 한 것으로, ABS 제어유닛(16)의 입력단에는 브레이크 페달(10)과 차속을 감지하는 차속센서(12)가 연결되어 있으며, 그 출력단에는 ABS 엑튜에이터(14)가 연결되어 있다.Here, the present invention is to provide a better braking effect by reducing the engine output because the ABS system is operated and the intake manifold blocks the intake air during sudden braking of the driver, the brake pedal () at the input of the ABS control unit 16 ( 10) and a vehicle speed sensor 12 for detecting a vehicle speed are connected, and an ABS actuator 14 is connected to the output end thereof.

따라서, 고속주행시 브레이크 페달(10)에 답력이 가해지면 ABS 제어유닛(16)은 ABS 엑튜에이터(14)를 통전제어하여 차륜에 ABS의 제동효과가 전달되도록 한 것이다.Therefore, when the pedaling force is applied to the brake pedal 10 during high-speed driving, the ABS control unit 16 controls the energization of the ABS actuator 14 to transmit the braking effect of the ABS to the wheels.

이에 더하여 본 발명은 엔진의 각 연소실마다 공기를 공급하도록 된 흡기다기관(20)의 입구(22)를 개폐토록 하는 개폐밸브(24)가 장착되어 있고, 상기 개폐밸브(24)의 작동은 밸브 제어유닛(18)이 밸브 엑튜에이터(26)를 통전제어하므로 이루어지는 것으로, 밸브 제어유닛(18)에 ABS 제어유닛(16)이 밸브작동신호를 출력하면 밸브 엑튜에이터(26)를 작동케 하는 것이다.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 the engine, the operation of the on-off valve 24 is valve control The unit 18 performs the energization control of the valve actuator 26. When the ABS control unit 16 outputs the valve operation signal to the valve control unit 18, the valve actuator 26 is operated.

따라서, 본 발명은 고속주행시 운전자가 브레이크 페달(10)를 밟아주면 ABS 제어유닛(16)이 이를 감지하여 각 차륜에 ABS가 작동되도록 ABS 엑튜에이터(14)를 구동케 하고, 이에 더하여 ABS 제어유닛(16)은 밸브 제어유닛(18)에 밸브작동신호를 출력한다.Therefore, in the present invention, when the driver presses the brake pedal 10 at high speed, the ABS control unit 16 detects this and drives the ABS actuator 14 to operate the ABS on each wheel, and in addition, the ABS control unit Numeral 16 outputs a valve operation signal to the valve control unit 18.

상기한 신호를 입력받은 밸브 제어유닛(18)이 밸브 엑튜에이터(26)를 통전제어하여 흡기다기관(20)에 설치된 개폐밸브(24)를 작동케 한다. 이에 개폐밸브(24)는 흡기다기관(20)의 입구(22)를 순간적으로 닫아주어 연소실로의 공기유입을 차단케 하므로 엔진의 출력이 줄어들게 된다.The valve control unit 18 receiving the above-mentioned signal energizes the valve actuator 26 to operate the on-off valve 24 installed in the intake manifold 20. The on-off valve 24 closes the inlet 22 of the intake manifold 20 instantaneously to block the inflow of air into the combustion chamber, thereby reducing the output of the engine.

상기한 바와 같이, 본 발명은 고속주행중인 차량의 운전자가 브레이크 페달(10)에 급격한 답력을 가하면, ABS 제어유닛(16)이 ABS 엑튜에이터(14)를 작동시킴과 더불어 밸브 제어유닛(18)으로 밸브작동신호를 출력하여 상기 밸브 제어유닛(18)이 밸브 엑튜에이터(26)를 제어토록 하고, 이에 흡기다기관(20)의 입구(22)는 개폐밸브(24)로 하여 순간적으로 폐쇄되므로 흡입공기의 감소에 의해 엔진출력이 저감되는 것으로, 급제동시 ABS 작동과 함께 엔진출력감소에 의해 보다 확실한 제동효과와 작동편리의 효과가 있다.As described above, according to the present invention, when the driver of the vehicle driving at high speed exerts a sudden effort on the brake pedal 10, the ABS control unit 16 operates the ABS actuator 14 and the valve control unit 18. The valve control unit 18 controls the valve actuator 26 by outputting a valve operation signal, and the inlet 22 of the intake manifold 20 is closed immediately by the on / off valve 24. The engine power is reduced by reducing the air, and the braking effect and the convenience of operation are more secured by reducing the engine power together with ABS operation during sudden braking.
