본 고안은 자동차의 브레이크장치에 관한 것으로, 통상의 유압브레이크에 의한 급제동시 제동토크를 자동으로 제어하여 줌으로서 차량바퀴가 완전히 로킹되는 것을 방지하여 차량이 안정상태를 유지하면서 제동거리의 단축 및 조향성을 향상하도록 한 액튜에이터를 이용한 자동차 유압브레이크 안티록(Anti-Lock) 장치에 관한 것이다.The present invention relates to a brake device of an automobile, and by controlling the braking torque automatically during normal braking by a normal hydraulic brake, preventing the vehicle wheels from being completely locked, reducing the braking distance and steering the vehicle while maintaining a stable state. The present invention relates to an automobile hydraulic brake anti-lock device using an actuator to improve the speed.
통상의 자동차에서는 차량의 운동에너지가 방향성을 갖고 있기 때문에 정지시에는 반대방향으로 작용하는 힘과 균형을 이룰 때 자동차가 멈추게 되며, 이때 반대방향으로 작용하는 힘은 차량자체에 설치된 브레이크가 타이어를 통하여 로면과의 마찰로 이 역할을 한다.In a typical vehicle, the kinetic energy of the vehicle has a directionality, so when the vehicle is stopped, the vehicle stops when it is balanced with the force acting in the opposite direction, and the force acting in the opposite direction is applied by the brake installed on the vehicle itself through the tire. Friction with the furnace surface plays this role.
그러나 차가 고속으로 달릴때는 항상 4륜에 동일하게 무게가 실리지 않을뿐 아니라 로면이 고르지 않기 때문에 접지력도 다르다.However, when the car is running at high speed, not only does it not carry the same weight on all four wheels, but also the grip is different because the road surface is uneven.
이러한 상태에서 브레이크를 밟으면 4륜중 1∼2개의 바퀴부터 로킹현상이 생기므로 로킹된 바뀌쪽으로 차량이 돌아가는 스핀현상이 생기거나 전륜의 조향능력이 없어져 핸들이 말을 듣지 않으므로 주행코스 바깥쪽으로 벗어나 버리게 된다.If brake is applied in this state, locking occurs from one or two wheels of the four wheels, and thus the spin phenomenon occurs when the vehicle is turned to the locked wheel, or the steering wheel of the front wheel is lost and the steering wheel does not listen. .
이러한 문제를 방지하기 위하여 운전자는 브레이크를 밟았다, 놓았다 하여 로킹상태가 계속되지 않도록 해주어야 한다.To prevent this problem, the driver should apply the brake and release the brake so that the locking does not continue.
따라서 이러한 문제점을 자동적으로 작동 해결하기 위하여 개발된 것이 ABS(Anti-Lock Brake System)로서 전자 제어장치를 이용하거나 기계적인 장치를 이용하여 초당 수회 이상 펌핑작용으로 운전자가 브레이크를 계속 밟고 있어도 브레이크 시스템 자체적으로 로킹상태를 순간적으로 풀어주는 기능을 하므로 안전운행이 가능하게 하는 것이다.Therefore, ABS (Anti-Lock Brake System) was developed to solve this problem automatically, and the brake system itself is used even if the driver continues to brake by pumping more than several times per second using an electronic control device or a mechanical device. The function of releasing the locking state instantaneously enables safe operation.
그러나 기계적인 장치에 의한 ABS는 구조가 단순한 반면 효과가 미비하여 확실한 효과를 기대할 수 없다.However, ABS, which is a mechanical device, has a simple structure and is ineffective, so a certain effect cannot be expected.
즉, 장치내에 고무로된 탄성체를 구비하여 유압을 단속 조절하도록 한 것으로 고무의 압축, 팽창으로 약간의 완충효과만을 기대할 수 있다.In other words, it is provided with a rubber elastic body in the device to control the hydraulic pressure can be expected only a slight buffering effect by the compression and expansion of the rubber.
또한 전자제어 장치를 이용한 ABS는 4개의 바퀴각각에 센서를 부착설치하여 바퀴의 회전상태 등을 감지하도록 한 후 복잡한 전자회로에 의해 각각의 브레이크를 개별적으로 제어하도록 한 것으로 명확한 효과를 얻을 수 있으나 구조가 매우 복잡하며 최초 자동차 생산시에 장착해야만 하므로 기 출고된 자동차는 장착시킬 수 없으며 설치단가가 매우 비싸므로 일반화 시키기에 문제가 있다.In addition, ABS using an electronic control device attaches sensors to each of the four wheels to detect the rotational state of the wheels, and then controls each brake individually by a complicated electronic circuit. Is very complicated and must be installed at the time of the first automobile production, the previously shipped cars can not be mounted and the installation cost is very expensive, so there is a problem to generalize.
이와같은 문제점을 개선 보완하기 위하여 안출된 본 고안에서는 간단한 전기적, 기계적 장치로 탁월한 효과를 얻을 수 있으며 기존의 차량에도 간편히 장착시켜 안전운행의 효과를 얻을 수 있는 액튜에이터를 이용한 자동차 유압브레이크 안티록 장치를 제공하는데 그 목적이 있다.In order to solve the above problems, the present invention can achieve excellent effects with simple electrical and mechanical devices, and can be easily mounted on an existing vehicle to provide an automobile hydraulic brake anti-lock device using an actuator. The purpose is to provide.
상기의 목적을 달성하기 위하여 본 고안은 유압라인의 일부분에 별도의 콘트롤러에 의해 제어되는 액튜에이터와 이에 일체로 되어 유압조절을 하는 피스톤 및 상기 콘트롤러의 작동을 지시통제할 수 있는 유압센서 스위치 등으로 구성됨을 특징으로 한다.In order to achieve the above object, the present invention consists of an actuator controlled by a separate controller on a part of a hydraulic line, a piston integrally connected thereto, and a hydraulic sensor switch capable of instructing and controlling the operation of the controller. It is characterized by.
이하 첨부된 도면에 의거하여 상세히 설명한다.Hereinafter will be described in detail with reference to the accompanying drawings.
제 1 도는 본 고안이 적용설치된 유압브레이크 시스템의 개략 계통도이다.1 is a schematic system diagram of a hydraulic brake system to which the present invention is applied.
브레이크 드럼(5)내의 휘일 실린더(6)와 유압을 가해주는 마스터실린더(2)사이를 연결하는 오일파이프(4)의 중간부에 본 고안 액튜에이터유압조절기(10)가 설치된 것이다.The actuator hydraulic regulator 10 of the present invention is installed at an intermediate portion of the oil pipe 4 connecting the wheel cylinder 6 in the brake drum 5 and the master cylinder 2 for applying hydraulic pressure.
액튜에이터유압조절기(10)는 밧데리(9)의 전원이 콘트롤러(8)를 통하여 단속적으로 액튜에이터코일(18)에 전달되도록 브레이크시스템 내의 유압을 자동조절하도록 한 것이다.The actuator hydraulic regulator 10 is to automatically adjust the hydraulic pressure in the brake system so that the power of the battery 9 is intermittently transmitted to the actuator coil 18 through the controller 8.
미설명부호(1)는 브레이크 패달이고 (3)은 브레이크 오일 탱크이다.Reference numeral 1 is a brake pedal and 3 is a brake oil tank.
제 2 도는 본 고안 액튜에이터유압조절기(10)의 분해사시도로서 내부에 이단실린더(14)가 내삽설치되고 하단에 3갈레의 연결구(12) 즉, 유압주입구(12a), 유압배출구(12b) 및 유압센서 스위치 결착구(12c)가 형성된 하부의 본체(11)와, 그 상부에는 액튜에이터코일(18) 및 자력판(17)에 의해 작동되는 작동봉(19) 및 완충스톱퍼(20)와 이를 지지 보호하는 보호캡(21)이 커버(22)와 결합판(16)에 의해 상기 본체(11)와 결합된 것이다.2 is an exploded perspective view of the actuator hydraulic regulator 10 of the present invention, and a two-stage cylinder 14 is inserted in the interior thereof, and a three-galle connector 12 is installed at the lower end thereof, that is, the hydraulic inlet 12a, the hydraulic outlet 12b, and the hydraulic pressure. The main body 11 of the lower part formed with the sensor switch fastener 12c, and the operating rod 19 and the buffer stopper 20 operated by the actuator coil 18 and the magnetic plate 17 on the upper part thereof, and the support protection thereof. The protective cap 21 is coupled to the main body 11 by the cover 22 and the coupling plate 16.
상기 본체(11) 내부의 이단실린더(14)는 본체(11)의 내벽과의 사이에서 오일누출이 방지되도록 하기 위하여 0-링(15a)이 설치되며 상부실린더(14a)와 하부실린더(14b) 사이에는 피스톤 로드(19a) 작동시 오일누출이 방지되도록 씰(15b)이 삽입되어 있다.The two-stage cylinder 14 inside the main body 11 is provided with a 0-ring 15a so as to prevent oil leakage between the inner wall of the main body 11 and the upper cylinder 14a and the lower cylinder 14b. The seal 15b is inserted therebetween to prevent oil leakage during the operation of the piston rod 19a.
또한 압력센서 스위치(13)는 일정압력 이상의 유압을 감지하면 스위치가 작동되도록 한 것으로 별도의 콘트롤러(8)와 도선 A(8a)으로 연결되고 콘트롤러(8)는 도선 B(18a)에 의해서 액튜에이터코일(18)에 연결되어 엑튜에이터의 작동여부를 조절한다.In addition, the pressure sensor switch 13 is to operate the switch when detecting the hydraulic pressure above a certain pressure is connected to a separate controller (8) and the conductor A (8a), the controller 8 is the actuator coil by the conductor B (18a) It is connected to (18) to control the operation of the actuator.
상부의 완충스톱퍼(20)와 스톱퍼보호캡(21)은 강력하게 밀려 상승하는 작동봉(19)을 정지시켜주는 것이며 커버(22)는 상기의 액튜에이터 작동부를 지지 보호하는 기능을 한다.The upper buffer stopper 20 and the stopper protective cap 21 stop the operating rod 19 to be pushed up strongly and the cover 22 serves to support and protect the actuator operating portion.
이와같이 구성된 본 고안의 작용 및 효과를 첨부도면 제 1 도와 제 3 도에 의거하여 설명한다.The operation and effects of the present invention constructed as described above will be described with reference to FIGS. 1 and 3 of the accompanying drawings.
운전자가 브레이크페달(1)을 밟으면 마스터실린더(2)에 의해 오일파이프(4)내의 유압이 상승한다.When the driver presses the brake pedal 1, the oil pressure in the oil pipe 4 is increased by the master cylinder 2.
오일파이프(4)내의 오일은 액튜에이터유압조절기(10)의 유압 주입구(12a)를 통하여 본체(11)내로 진입되고 동시에 유압배출구(12b)를 통하여 브레이크 휘일실린더(6)에 유압이 전해져 브레이크라이닝(7)이 브레이크드럼(8)에 밀착되도록 한다.The oil in the oil pipe (4) enters the main body (11) through the hydraulic inlet (12a) of the actuator hydraulic regulator (10), and at the same time, hydraulic pressure is transmitted to the brake wheel cylinder (6) through the hydraulic outlet (12b) and brake lining ( 7) is in close contact with the brake drum (8).
동시에 본체(11)의 피스톤로드(19a)와 압력센서 스위치(13)에도 유압이 전달되므로서 피스톤로드(19a)는 제 3b 도와 같이 상승되고 유압센서스위치(13)가 일정 이상 유압을 감지하게 되면 콘트롤러(8)를 동작시킨다.At the same time, since the hydraulic pressure is also transmitted to the piston rod 19a and the pressure sensor switch 13 of the main body 11, the piston rod 19a is raised as shown in the 3b degree, and the hydraulic sensor switch 13 detects the hydraulic pressure more than a certain level. Operate the controller 8.
제 3b 도와 같이 피스톤로드(19a)가 상승되면 그만큼 공간이 확장되므로서 브레이크 시스템내의 유압이 급격히 저하되므로 브레이크 휘일실린더(6)에도 압력이 저하되므로 브레이크가 순간적으로 살짝 풀어지는 결과가 된다.As shown in FIG. 3B, when the piston rod 19a is raised, the space is expanded so that the hydraulic pressure in the brake system is rapidly lowered, and thus the pressure is also lowered in the brake wheel cylinder 6, resulting in a momentary release of the brake.
상기 콘트롤러(8)는 1초당 14회 이상으로 전원을 단속하여 주도록 한 것으로서 액튜에이터코일(18)과 상호 연결되어 있으므로 전원이 공급되면 액튜에이터코일(18)에 자장이 형성되어 내부의 작동봉(19)을 하강시키게 되므로 따라서 피스톤로드(19a)가 본체(11)의 이단실린더(14) 내부로 하강 진입한다.The controller 8 is to interrupt the power more than 14 times per second, and is connected to the actuator coil 18, so when a power is supplied, a magnetic field is formed in the actuator coil 18 so that the operating rod 19 Therefore, since the piston rod 19a descends into the two-stage cylinder 14 of the main body 11.
따라서 본체(11)내부의 유압은 순간적으로 증가하게 되며 유압은 유압배출구(12b)를 통하여 브레이크 휘일실린더(6)에 전달된다.Therefore, the hydraulic pressure in the main body 11 is instantaneously increased, and the hydraulic pressure is transmitted to the brake wheel cylinder 6 through the hydraulic outlet 12b.
즉 제 3a 도와 같은 상태로서 브레이크를 매우 세게 걸어주는 결과가 된다.That is, the result is that the brake is applied very hard in the same state as the 3rd degree.
반대로 콘트롤러(8)가 액튜에이터코일(18)에 전원을 공급하지 않게 되면, 즉시 자장이 없어지면서 유압에 의하여 피스톤로드(19a)가 밀리면서 작동봉(19)이 상승하여 다시 제 3b 도와 같은 상태가 된다.On the contrary, when the controller 8 does not supply power to the actuator coil 18, the magnetic field disappears immediately and the piston rod 19a is pushed by the hydraulic pressure and the operating rod 19 is raised to return to the state of the 3b degree. do.
이때는 브레이크 시스템내의 유압이 낮아진 상태로서 브레이크휘일실린더(6)에도 유압이 감소되어 브레이크를 약하게 걸어주는 상태가 된다.At this time, as the hydraulic pressure in the brake system is lowered, the hydraulic pressure is also reduced in the brake wheel cylinder 6, so that the brake is weakly applied.
따라서 본 고안은 콘트롤러(8)가 1초에 14회 이상 전원을 단속하므로서 브레이크 시스템내부의 압력변화 즉, 상기의 설명과 같은 상태가 14회/초 이상 반복작동된다.Therefore, in the present invention, the controller 8 controls the power more than 14 times per second, so that the pressure change in the brake system, that is, the same state as described above, is repeatedly operated 14 times / second or more.
이상 살펴본 바와같이 본 고안은 운전자가 브레이크 페달을 연속적으로 세게 밟고 있더라도 본 고안 액튜에이터 유압조절기에 의해 브레이크 라인내의 유압을 순간적으로 자동변화시켜주도록 함으로서 급제동 시에도 어느 한쪽 바퀴만이 로킹되는 것을 방지하고 압력이 분산되어 전달되므로 고속주행중 브레이크 작동시에도 운전자의 임의대로 조향이 가능하며 정차시 제동거리 역시 짧아지므로 자동차 안전운행에 크게 기여할 수 있는 매우 유용한 고안이다.As described above, the present invention allows the actuator hydraulic regulator of the present invention to instantaneously change the hydraulic pressure in the brake line even when the driver presses the brake pedal continuously, thereby preventing only one of the wheels from locking during sudden braking and pressure Since the transmission is distributed, it is possible to steer at the driver's discretion even when operating the brakes during high-speed driving, and the braking distance is shortened when stopping, which is a very useful design that can greatly contribute to the safe driving of the vehicle.
