Description
본 발명은 자동차의 제동장치에 관한 것으로, 특히 주행중인 차량의 급제동시 제동거리를 단축시켜 안전사고를 예방하거나 또는 최소화시킬 수 있도록 된 자동차의 제동장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a braking device for an automobile, and more particularly, to a braking device for a vehicle that can prevent or minimize a safety accident by shortening a braking distance during a sudden braking of a driving vehicle.
일반적으로, 제동장치(break system)란 주행하는 자동차에 제동력을 발생시켜 자동차가 스스로 움직이지 않도록 하는 장치로서, 보통 브레이크페달의 조작에 따라 마스터실린더에서 발생/공급되는 유압에 의해 작동되게 된다.In general, a brake system is a device that generates a braking force on a driving vehicle so that the vehicle does not move by itself, and is normally operated by hydraulic pressure generated / supplied from the master cylinder according to the operation of the brake pedal.
즉, 종래의 제동장치에 대해 간략하게 설명하면 제동력을 발생시키기 위해 운전자가 발로 밟아주게 되는 브레이크페달과, 이 브레이크페달의 밟는 힘을 증폭 또는 확대시키도록 된 배력장치와, 상기 브레이크페달의 밟는 힘을 유압으로 전환시키도록 된 마스터실린더 및, 이 마스터실린더로부터 유압을 공급받아 실질적인 제동력을 발생시키도록 된 브레이크본체등으로 구성되어 있다.That is, a brief description of a conventional braking device includes a brake pedal to be stepped on by a driver to generate a braking force, a power supply device to amplify or enlarge the stepping force of the brake pedal, and a stepping force of the brake pedal. The master cylinder is configured to convert oil into hydraulic pressure, and the brake body is configured to generate a substantial braking force by receiving hydraulic pressure from the master cylinder.
따라서, 운전자가 브레이크페달을 밟아주게 되면 페달의 밟는 힘이 마스터실린더에 의해 유압으로 전환되면서 브레이크파이프와 오일분배기 및 브레이크호스등을 통해 브레이크본체로 공급되게 되고, 이 브레이크본체로 공급된 유압은 브레이크슈 또는 브레이크패드를 드럼이나 디스크로 압착시킴으로써 그 마찰력에 의한 제동력을 발생시켜 주행중인 자동차를 정지시키게 된다.Therefore, when the driver presses the brake pedal, the pedal's pressing force is converted into hydraulic pressure by the master cylinder and supplied to the brake body through the brake pipe, the oil distributor, and the brake hose, and the hydraulic pressure supplied to the brake body is braked. By pressing the shoe or brake pad with a drum or a disk, a braking force generated by the frictional force is generated to stop the driving vehicle.
그러나, 상기와 같은 종래의 제동장치를 이용하는 차량은 급제동시 바퀴는 마찰력에 의해 회전이 중지되지만 차량은 가속력 때문에 주행방향으로 미끄러지면서 제동거리가 길어지게 되고, 이로 인해 바퀴의 수명이 단축됨은 물론 더욱 심하게는 물적 및 인적피해가 발생되는 문제점이 있었다.However, in the case of a vehicle using the conventional braking device as described above, the wheel stops rotating due to friction force, but the vehicle slides in the driving direction due to the acceleration force, and thus the braking distance becomes longer, thereby shortening the life of the wheel. Seriously, there was a problem that physical and human damage occurred.
이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 급제동시 구동륜차축의 회전력을 이용해 유동륜차축의 회전방향을 상기 구동륜차축과 반대되는 방향으로 회전시키면서 상기 유동륜차축의 회전력을 이용해 구동륜차축의 회전력을 일차적으로 감소시키고, 상기 구동륜차축의 나머지 회전력은 브레이크 마찰력에 의해 최종적으로 제거함으로써, 전체적인 제동거리를 단축시키고 이로 인해 바퀴의 수명이 단축되는 것을 최대한 예방하며, 아울러 물적 및 인적피해를 최소화시키거나 또는 미리 예방시킬 수 있도록 된 자동차의 제동장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by rotating the direction of rotation of the flow wheel axle by using the rotational force of the driving wheel axle in the direction opposite to the driving wheel axle by using the rotational force of the driving wheel axle of the driving wheel axle By reducing the rotational force primarily, the remaining rotational force of the drive wheel axle is finally removed by the brake frictional force, thereby minimizing the overall braking distance and thereby minimizing the life of the wheels, and minimizing physical and human damage. It is an object of the present invention to provide a braking device for a vehicle which can be prevented or prevented in advance.
상기와 같은 목적을 달성하기 위한 본 발명의 제동장치는, 이그니션스위치와 차속센서 및 휠속도센서를 이용해 차량이 주행상태임을 판별하고 상기 차속센서와 휠속도센서 및 브레이크페달스위치를 이용해 급제동상태임을 판별하는 전자제어유니트와, 구동륜차축상에 설치되는 구동륜차축기어와, 유동륜차축상에 설치되는 유동륜차축기어와, 급제동시 구동륜과 유동륜의 회전이 정지되기 전에 상기 전자제어유니트의 제어에 따라 구동륜차축기어와 유동륜차축기어에 각각 치합되면서 상기 구동륜과 유동륜의 회전이 정지되면 치합상태가 해제되도록 위치이동되는 한쌍의 구동력전달수단과, 이 구동력전달수단을 연결하면서 구동륜차축의 회전동력에 반대되는 회전동력을 유동륜차축에 전달하여 상기 구동륜차축의 회전동력을 감속시키는 동력전달벨트로 구성되는 것을 특징으로 한다.The braking device of the present invention for achieving the above object, by using the ignition switch, the vehicle speed sensor and the wheel speed sensor to determine that the vehicle is in a driving state, and the vehicle braking state by using the vehicle speed sensor, wheel speed sensor and brake pedal switch An electronic control unit, a drive wheel axle gear provided on the drive wheel axle, a flow wheel axle gear provided on the flow wheel axle, and a drive wheel axle according to the control of the electronic control unit before the rotation of the drive wheel and the flow wheel stops during sudden braking.

도 1은 본 발명의 제동장치에 사용되는 개략적인 회로구성도이고, 도 2와 도 3은 본 발명에 따른 제동장치의 구성을 설명하기 위한 사시도로서, 본 발명에 따른 제동장치는 종래에 사용되던 제동시스템과 급제동시 구동륜과 유동륜의 회전이 정지되기 전(즉 슬립이 발생되기 전)에 구동륜차축의 회전동력을 감속시키는 시스템이 함께 포함되어 구성되게 된다.1 is a schematic circuit diagram used in the braking device of the present invention, Figures 2 and 3 are perspective views for explaining the configuration of the braking device according to the present invention, the braking device according to the present invention was used in the prior art The braking system and the system for decelerating the rotational power of the driving wheel axle before the rotation of the driving wheel and the flow wheel are stopped (that is, before the slip is generated) are included.
즉, 본 발명에 따른 제동장치는 제동력을 발생시키기 위해 운전자가 발로 밟아주게 되는 브레이크페달과, 이 브레이크페달의 밟는 힘을 증폭 또는 확대시키도록 된 배력장치와, 상기 브레이크페달의 밟는 힘을 유압으로 전환시키도록 된 마스터실린더 및, 이 마스터실린더로부터 유압을 공급받아 실질적인 제동력을 발생시키도록 된 브레이크본체등으로 구성된 일반적인 장치와 더불어, 도 1과 도 2에 도시된 바와 같이 이그니션스위치(1)와 차속센서(2) 및 휠속도센서(3)를 이용해 차량이 주행상태임을 판별하고 상기 차속센서(2)와 휠속도센서(3) 및 브레이크페달스위치(4)를 이용해 급제동상태임을 판별하는 전자제어유니트(10)와, 구동륜차축(11)상에 설치되는 구동륜차축기어(21)와, 유동륜차축(13)상에 설치되는 유동륜차축기어(22)와, 급제동시 구동륜(12)과 유동륜(14)의 회전이 정지되기 전에 상기 전자제어유니트(10)의 제어에 따라 구동륜차축기어(21)와 유동륜차축기어(22)에 각각 치합되면서 상기 구동륜(12)과 유동륜(14)의 회전이 정지되면 치합상태가 해제되도록 위치이동되는 한쌍의 구동력전달수단(30,40)과, 이 구동력전달수단(30,40)을 연결하면서 구동륜차축(11)의 회전동력에 반대되는 회전동력을 유동륜차축(13)에 전달하여 상기 구동륜차축(11)의 회전동력을 감속시키는동력전달벨트(50)를 더 포함하여 구성되는 구조로 되어 있다.That is, the braking device according to the present invention includes a brake pedal to be stepped on by the driver to generate a braking force, a booster device to amplify or enlarge the stepping force of the brake pedal, and a stepping force of the brake pedal to be hydraulically applied. The ignition switch 1 and the vehicle speed as shown in Figs. 1 and 2, as well as a general device composed of a master cylinder adapted to be switched and a brake body adapted to generate a substantial braking force by receiving hydraulic pressure from the master cylinder. An electronic control unit for determining that the vehicle is in a driving state by using the sensor 2 and the wheel speed sensor 3, and determining that the vehicle is in a rapid braking state by using the vehicle speed sensor 2, the wheel speed sensor 3, and the brake pedal switch 4. 10, the drive wheel axle gear 21 provided on the drive wheel axle 11, the flow wheel axle gear 22 provided on the flow wheel axle 13, and the drive wheel 12 during braking. And the driving wheel 12 and the flow wheel 14 are engaged with the driving wheel axle gear 21 and the flow wheel axle gear 22 under the control of the electronic control unit 10 before the rotation of the flow wheel 14 is stopped. The rotational power opposite to the rotational power of the driving wheel axle 11 is connected to the pair of driving force transmission means 30 and 40 and the driving force transmission means 30 and 40 which are moved in position so that the engagement state is released when the rotation of the motor is stopped. It is configured to further include a power transmission belt 50 for transmitting to the flow wheel axle 13 to reduce the rotational power of the drive wheel axle (11).
한편, 상기 전자제어유니트(10)는 브레이크페달스위치(4)가 온(ON)이고 주행차속에 대비하여 구동륜(12)의 회전속도가 급격하게 감소되면 급제동상태로 판별하게 된다.On the other hand, the electronic control unit 10 determines that the brake pedal switch 4 is ON and the braking state when the rotational speed of the driving wheel 12 is sharply reduced in preparation for the traveling vehicle speed.
그리고, 상기 구동력전달수단(30,40)은 스프링과 함께 조합되어 구동륜차축(11)과 유동륜차축(13)부근의 차체에 각각 고정되도록 설치되면서 급제동시 전자제어유니트(10)의 제어에 따라 피스톤운동을 하는 제1,2솔레노이드(31,41)와, 이 제1,2솔레노이드(31,41)의 이동에 연동하여 각각 승하강되는 솔레노이드로드(32,42)와, 이 솔레노이드로드(32,42)의 선단에 감싸여지면서 자유회전이 가능하도록 설치되는 기어연결축(33,43)과, 이 기어연결축(33,43)의 일단에 각각 결합되면서 상기 솔레노이드로드(32,42)의 승강이동에 따라 구동륜차축기어(21) 및 유동륜차축기어(22)에 선택적으로 치합되는 치합기어(34,44)와, 상기 기어연결축(33,43)의 타단에 각각 결합되면서 동력전달벨트(50)에 의해 연결되도록 설치되는 회전력전달기어(35,45)로 구성된다.The driving force transmitting means 30 and 40 are combined with the spring to be fixed to the vehicle body near the driving wheel axle 11 and the flow wheel axle 13, respectively, and under the control of the electronic control unit 10 during sudden braking. The first and second solenoids 31 and 41, which make a piston movement, the solenoid rods 32 and 42, which are raised and lowered in conjunction with the movement of the first and second solenoids 31 and 41, respectively, and the solenoid rod 32 And the gear connecting shafts 33 and 43 which are installed at the ends of the gear connecting shafts 33 and 43 so as to be freely rotated, and are respectively coupled to one end of the gear connecting shafts 33 and 43, respectively. The power transmission belt is coupled to the gearing gears 34 and 44 selectively engaged with the driving wheel axle gear 21 and the flow wheel axle gear 22 according to the lifting movement, and the other ends of the gear connecting shafts 33 and 43, respectively. It consists of a rotational force transmission gear (35, 45) is installed to be connected by (50).
따라서, 차량의 주행중 운전자가 브레이크페달을 밟아 주게 되면 전자제어유니트(10)는 차속센서(2)와 휠속도센서(3)로부터 검출된 값을 비교하여 차량이 급제동상태인지를 또는 정상 제동상태인지를 판별하게 되는바, 즉 상기 전자제어유니트(10)가 현재의 주행차속에 비해 구동륜(12)의 회전속도가 급격하게 감소되었다고 판단하게 되면 차량이 급제동상태인 것으로 판단하게 된다.Therefore, when the driver presses the brake pedal while the vehicle is running, the electronic control unit 10 compares the values detected from the vehicle speed sensor 2 and the wheel speed sensor 3 to determine whether the vehicle is in a sudden braking state or a normal braking state. That is, if the electronic control unit 10 determines that the rotational speed of the driving wheel 12 is drastically reduced compared to the current driving vehicle speed, it is determined that the vehicle is in a sudden braking state.
그리고, 상기 전자제어유니트(10)에 의해 주행차량이 급제동상태인 것으로판단되면, 상기 전자제어유니트(10)는 제1,2트랜지스터(5,7)를 각각 온(ON)시켜 제1,2릴레이(6,8)를 작동시키고 이어서 제1,2솔레노이드(31,41)를 작동시키게 된다.In addition, when it is determined by the electronic control unit 10 that the traveling vehicle is in a sudden braking state, the electronic control unit 10 turns on the first and second transistors 5 and 7 to respectively turn on the first and second transistors. The relays 6 and 8 are activated, followed by the first and second solenoids 31 and 41.
여기서, 상기 제1,2솔레노이드(31,41)는 각각 고정전자석과 이동전자석 및 이들 사이에 설치된 압축스프링으로 구성되는데, 상기 전자제어유니트(10)에 의해 고정전자석과 이동전자석이 자화(磁化)되면 상기 이동전자석은 압축스프링의 복원력을 이기고 고정전자석쪽으로 상승되는 즉 피스톤운동을 하게 된다.Here, the first and second solenoids (31, 41) is composed of a fixed electromagnet and a mobile electromagnet and a compression spring provided between them, respectively, the fixed electromagnet and the mobile electromagnet is magnetized by the electronic control unit (10) When the moving electromagnets overcome the restoring force of the compression springs, the moving electromagnets are lifted toward the fixed electromagnets, i.
그리고, 상기 이동전자석과 일체로 결합된 각각의 솔레노이드로드(32,42)는 피스톤운동에 연동하여 승하강 이동을 하게 되는데, 상기 제1,2솔레노이드(31,41)의 전자석이 자화되면 솔레노이드로드(32,42)는 승강이동을 하게 되고, 이에 따라 한쌍의 치합기어(34,44)는 도 3에 도시된 바와 같이 구동륜차축기어(21) 및 유동륜차축기어(22)에 각각 치합되게 된다.Each solenoid rod 32 and 42 coupled to the moving electromagnet moves up and down in conjunction with a piston movement. When the electromagnets of the first and second solenoids 31 and 41 are magnetized, the solenoid rod 32 and 42 are moved up and down, so that the pair of gearing gears 34 and 44 are engaged with the driving wheel axle gear 21 and the flow wheel axle gear 22, respectively, as shown in FIG. .
한편, 상기 구동륜차축(11)쪽의 치합기어(34)가 구동륜차축기어(21)와 치합되면 회전력전달기어(35)는 도시된 화살표와 같이 구동륜차축(11)과 동일한 방향으로 회전되게 되고, 이 회전력은 동력전달벨트(50)를 통해 유동륜차축(13)쪽의 회전력전달기어(45)로 전달되는데, 상기 동력전달벨트(50)의 중간부위가 도시된 바와 같이 엑스(X)자의 모양으로 비틀어져 있기 때문에 상기 구동륜차축(11)쪽의 회전력전달기어(35)와 유동륜차축(13)쪽의 회전력전달기어(45)는 서로 반대되는 방향으로 회전되게 된다.On the other hand, when the engagement gear 34 of the driving wheel axle 11 is engaged with the driving wheel axle gear 21, the rotational force transmission gear 35 is rotated in the same direction as the driving wheel axle 11 as shown in the arrow, This rotational force is transmitted to the rotational force transmission gear 45 toward the flow wheel axle 13 through the power transmission belt 50, the middle portion of the power transmission belt 50 as shown in the shape of the X (X) Since the rotational force transmission gear 35 toward the driving wheel axle 11 and the rotational force transmission gear 45 toward the flow wheel axle 13 are rotated in opposite directions.
그리고, 상기 회전력전달기어(45)의 회전력이 치합기어(44)를 통해 유동륜차축기어(22)에 전달되면, 상기 유동륜차축(13) 및 유동륜(14)은 도시된 화살표와 같이 구동륜(12)과 반대되는 회전방향으로 회전되게 되고, 이로 인해 상기 구동륜(12)의 회전속도가 일차적으로 감소되게 된다.In addition, when the rotational force of the rotational force transmission gear 45 is transmitted to the flow wheel axle gear 22 through the engagement gear 44, the flow wheel axle 13 and the flow wheel 14 are driven as shown by the arrow shown in the driving wheel ( It is rotated in the opposite rotational direction as 12), thereby reducing the rotational speed of the drive wheel 12 primarily.
이와 같이, 상기 구동륜(12)의 회전속도가 본 발명에 따른 제동장치에 의해 일차적으로 감소되고 나면 이와 동시에 상기 구동륜(12)에는 브레이크 마찰열에 의한 제동력이 발생되면서 그 회전은 완전히 정지되게 된다.As such, after the rotational speed of the driving wheel 12 is primarily reduced by the braking device according to the present invention, the driving wheel 12 is simultaneously braked by the brake frictional heat, and the rotation thereof is completely stopped.
따라서, 본 발명에 따른 제동장치를 장착한 차량이 주행중 급제동을 하게 되면 구동륜(12)의 회전력이 일차적으로 감소된 상태에서 브레이크 마찰열에 의해 완전히 정지되게 됨으로써, 브레이크 마찰열만을 이용해 차량을 급제동시키던 종래의 제동장치에 비해 제동거리가 크게 단축되는 잇점이 있게 되고, 아울러 구동륜(12)과 유동륜(14)의 수명이 단축되는 것을 최대한 예방할 수 있게 된다.Therefore, when the vehicle equipped with the braking device according to the present invention suddenly brakes while driving, the vehicle is completely stopped by the brake frictional heat while the rotational force of the driving wheel 12 is primarily reduced, thereby rapidly braking the vehicle using only the brake frictional heat. Compared to the braking device, there is an advantage in that the braking distance is greatly shortened, and the life of the driving wheel 12 and the flow wheel 14 can be prevented as much as possible.
또한, 본 발명에 따른 제동장치로 인해 급제동시 제동거리가 단축되면 물적 및 인적피해를 최소화시키거나 또는 미리 예방시킬 수 있는 잇점도 기대할 수 있게 된다.In addition, due to the braking device according to the present invention, if the braking distance is shortened during braking, it is possible to expect an advantage of minimizing or preventing physical and human damage.
한편, 상기 구동륜(12)과 유동륜(14)의 회전이 완전히 정지되면 전자제어유니트(10)의 제어에 의해 자화되었던 제1,2솔레노이드(31,41)의 전자석이 해제되게 되고, 이로 인해 각각의 솔레노이드로드(32,42)가 하강이동되면서 치합기어(34)와 구동륜차축기어(21)의 치합 및 치합기어(44)와 유동륜차축기어(22)의 치합도 해제되게 되며, 이에 따라 급제동시 작동되었던 본 발명에 따른 제동장치도 정상상태로 복원되어 차량은 정상주행을 하거나 또는 정상적인 제동을 할 수 있게 된다.On the other hand, when the rotation of the driving wheel 12 and the flow wheel 14 is completely stopped, the electromagnets of the first and second solenoids 31 and 41 that are magnetized by the control of the electronic control unit 10 are released. As the solenoid rods 32 and 42 move downward, the engagement of the engagement gear 34 and the driving wheel axle gear 21 and the engagement of the engagement gear 44 and the flow wheel axle gear 22 are also released. The braking device according to the present invention, which was operated during operation, is also restored to a normal state so that the vehicle can drive normally or perform a normal braking.
이상 설명한 바와 같이 본 발명에 의하면, 주행중인 차량의 급제동시 구동륜의 회전력이 유동륜의 회전력에 의해 일차적으로 감소된 상태에서 브레이크 마찰열에 의해 완전히 정지되어져, 제동거리가 크게 단축되게 되고, 이로 인해 구동륜과 유동륜의 수명이 단축되는 것을 최대한 예방할 수 있게 되며, 아울러 물적 및 인적피해가 최소화시키거나 또는 미리 예방되는 효과가 있게 된다.As described above, according to the present invention, the braking distance of the driving wheel is completely stopped by the heat of the brake friction in a state where the rotational force of the driving wheel is first reduced by the rotational force of the flow wheel, and the braking distance is greatly shortened. It is possible to prevent the life cycle of the flow wheel as much as possible, and to minimize or prevent physical and human damage.
