본 발명은 전기적 제어를 통한 파킹브레이크에 관한 것으로,The present invention relates to a parking brake through electrical control,

특히, 모터의 회전을 전달받은 푸시로드가 너트조절부재를 동작시켜 주차용 케이블을 당기는 불편 없이 안전하게 주차를 할 수 있도록 하는 전기적 제어를 통 한 파킹브레이크에 관한 것이다.
In particular, the push rod received the rotation of the motor relates to the parking brake through the electrical control to operate the nut control member to safely park without the inconvenience of pulling the parking cable.

일반적으로 차량의 브레이크는 발을 이용해서 조작하도록 된 풋 브레이크와, 손을 이용해서 조작하도록 된 핸드 브레이크의 두 가지로 구분할 수 있으며, 파킹 브레이크는 역시 풋브레이크와 핸드브레이크 타입이 모두 사용되고 있다.In general, a brake of a vehicle can be classified into two types: a foot brake to be operated by a foot and a hand brake to be operated by a hand, and a parking brake is a foot brake and a hand brake type.

상기 파킹 브레이크는 차량을 주차시킨 후 파킹 브레이크의 레버를 잡아당기거나 패달을 밟으면 풀리가 맞물려 회전하게 되어 풀리에 연결된 케이블이 당겨져 파킹 브레이크를 동작시킴으로써 정지되어 있는 차량이 외부 힘으로 인해 움직이지 않도록 하고, 만일 비탈진 장소에 차량이 주차되어 있더라도 미끄러지지 않도록 작용하게 된다.When the parking brake parks the vehicle and pulls the lever of the parking brake or presses the pedal, the pulley engages and rotates so that the cable connected to the pulley is pulled to operate the parking brake so that the stopped vehicle does not move due to external force. If the vehicle is parked in a non-ventilated place, the vehicle does not slip.

그리고 파킹 브레이크를 걸어 놓았다고 해도 지나가는 차량으로부터 충돌을 받았거나 또는 만약 걸어 놓았던 파킹 브레이크가 해체될 경우에는 차량이 굴러가게 되어 위험이 따르기 때문에 바퀴 사이사이에 돌이나 버팀목을 놓아 굴러가는 것을 방지한다.And even if you put the parking brake on, if you are hit by a passing vehicle or if the parking brake you have disassembled is dismantled, the vehicle will roll and you will be at risk, so put a stone or crutch between the wheels to prevent rolling.

그러나 상기 파킹 브레이크의 레버를 조작하려면 한 손으로 많은 힘을 써서 잡아 당겨야 하고, 특히 빈번히 주정차를 하게되는 운전자는 허리 부상 및 팔에 무리를 줄 뿐만 아니라, 상기 파킹 브레이크 레버가 콘솔 중앙에 위치하여 실내공간 활용에 제약을 주는 문제점이 있었다.However, in order to operate the lever of the parking brake, it is necessary to pull it out with a large amount of force with one hand, and in particular, a driver who frequently stops not only hurts his back and arms, but also places the parking brake lever in the center of the console. There was a problem of limiting space utilization.

상기와 같은 문제점을 해소하기 위하여 전기적 신호에 의해 동작하는 모터로 파킹브레이크를 자동으로 동작시키는 장치가 개발되었으나, 이러한 장치는 도 1에 도시된 바와 같이 모터(1)의 회전을 원동기어(1a)와 릴레이기어(1b) 및 종동기어(1c)로 전달하고, 리턴스프링(3)과 와셔웨이브(3a) 및 스페이서(3c)가 구비된 푸시로드(2)에 나사부(2a)를 형성하여 나사부(2a)를 종동기어(1c)에 체결한다.In order to solve the above problems, an apparatus for automatically operating a parking brake with a motor operated by an electrical signal has been developed. However, such a device is adapted to control the rotation of the motor 1 as shown in FIG. And a threaded portion 2a on a push rod 2 provided with a return spring 3, a washer wave 3a, and a spacer 3c, which are transferred to the relay gear 1b and the driven gear 1c. 2a) is fastened to the driven gear 1c.

또한 상기 푸시로드(2)의 단부에는 클러치(4)를 구비하여 리턴시일(5a)이 구비된 너트조절부재(5)내에 클러치(4)를 구비하며, 상기 너트조절부재(5)와 핑거(6a) 사이에는 디스크(9)의 양측에 구비된 인너 패드플레이트(7)와 아웃터 패드플레이트(8)를 마련한다.In addition, the end of the push rod (2) is provided with a clutch (4) and a clutch (4) in the nut adjusting member (5) provided with a return seal (5a), the nut adjusting member (5) and the finger ( Inner pad plates 7 and outer pad plates 8 provided on both sides of the disk 9 are provided between 6a).

이때 상기 너트조절부재(5)측에는 인너패드(7a)가 구비된 인너패트플레이(7)를 마련하고, 하우징(6)의 핑거(6a)측에는 아웃터패드(8a)가 구비된 아웃터 패드플레이트(8)를 마련하여 구성하였다.At this time, the inner pad play 7 having the inner pad 7a is provided at the nut adjusting member 5 side, and the outer pad plate 8 having the outer pad 8a at the finger 6a side of the housing 6. ) Was prepared and configured.

상기와 같이 구성된 종래의 모터에 의한 파킹브레이트는 전기적신호에 의해 모터(1)에 전원이 인가되면 모터(1)의 축에 고정된 원동기어(1a)가 회전하면서 그 회전을 릴레이기어(1b)에 전달하고, 그 릴레이기어(1b)는 회전을 종동기어(1c)에 전달한다.As described above, when the power is applied to the motor 1 by an electrical signal, the parking braid by the conventional motor configured as described above rotates the rotational gear 1a fixed to the shaft of the motor 1 while the relay gear 1b rotates. And the relay gear 1b transmits the rotation to the driven gear 1c.

이때 상기 종동기어(1c)에는 푸시로드(2)의 나사부(2a)가 체결되어 있으며, 그 나사부(2a)는 회전하는 종동기어(1c)에 의해 종동기어(1c)에서 풀려 리턴스프링(3)을 압축하면서 전진한다.At this time, the threaded portion 2a of the push rod 2 is fastened to the driven gear 1c, and the threaded portion 2a is released from the driven gear 1c by the rotating driven gear 1c and the return spring 3 Advance while compressing.

상기 나사부(2a)의 전진에 의해 전진되는 푸시로드(2)는 와셔웨이브(3a)와 스페이서(3b)를 누르면서 클러치(4)를 너트조절부재(5)에 밀착되므로 너트조절부재(5)가 전진하면서 인너패드플레이트(7)를 통해 인너패드(7a)를 디스크(9)에 밀착시 킴과 동시에 핑거(6a)는 아웃터패드플레이트(8)를 통해 아웃터패드(8a)를 디스크(9)에 밀착시켜 차량을 파킹시키도록 한 것이다.The push rod 2 advanced by the advancement of the screw portion 2a is in close contact with the nut 4 and the nut adjusting member 5 while pressing the washer wave 3a and the spacer 3b. While advancing, the inner pad 7a is brought into close contact with the disk 9 through the inner pad plate 7, and at the same time, the finger 6a moves the outer pad 8a through the outer pad plate 8 to the disk 9. The vehicle was parked in close contact.

그러나 상기와 같은 종래의 모터(1)를 사용하는 파킹브레이크는 푸시로드(2)에 형성된 나사부(2a)를 종동기어(1c)에 직접 체결하고 그 푸시로드의 대향측은 너트조절부재(5)를 밀도록 한 것이므로 주차력의 반력이 푸시로드(2)를 통해 종동기어(1c)에 전달되고 이로 인하여 종동기어(1c)가 변형되는 문제점이 발생되었을 뿐만 아니라, 다수의 기어를 사용하는 등 구조가 복잡해지는 문제점도 있었다.
However, the parking brake using the conventional motor 1 as described above fastens the screw portion 2a formed on the push rod 2 directly to the driven gear 1c, and the opposite side of the push rod has a nut adjusting member 5. Since the reaction force of the parking force is transmitted to the driven gear 1c through the push rod 2, and the driven gear 1c is deformed due to the pushing force, and the structure is used such as using a plurality of gears. There was also the problem of becoming complicated.

따라서 본 발명의 목적은 모터의 회전을 전달받은 푸시로드가 리턴스프링을 압축하면서 클러치와 너트조절부재를 전진시켜 디스크를 클램핑할 수 있도록 함으로써 간소화된 구성으로 푸시로드를 동작시키고 디스크를 클램핑할 수 있을 뿐만 아니라, 모터의 회전축에 직접 결합된 푸시로드로 너트조절부재를 밀어서 핑거와 너트조절부재 사이에 디스크를 클램핑할 수 있도록 한 전기적 제어를 통한 파킹브레이크를 제공함에 있다.

In addition, the present invention provides a parking brake through electrical control that allows the disk to be clamped between the finger and the nut adjusting member by pushing the nut adjusting member directly to the push rod coupled to the rotating shaft of the motor.

이러한 본 발명의 목적은 모터의 회전을 푸시로드에 전달하여 푸시로드가 전, 후진 동작되도록 하고, 그 푸시로드의 전진과 동시에 너트조절부재가 동작되며, 상기 푸시로드가 삽입되는 하우징의 핑거와 너트조절부재 사이에는 디스크와 한쌍 의 패드플레이트를 구비한 파킹브레이크에 있어서, 상기 모터의 회전축 선단을 푸시로드에 직접 결합하여 회전축의 회전 방향에 따라 푸시로드가 전후진 하면서 너트조절부재를 전후진시킬 수 있도록 구성됨을 특징으로 한다.
The object of the present invention is to transmit the rotation of the motor to the push rod to make the push rod forward, backward operation, the nut adjusting member is operated at the same time as the push rod forward, the finger and nut of the housing is inserted into the push rod In the parking brake provided with a disk and a pair of pad plates between the adjusting members, the front end of the rotating shaft of the motor is directly coupled to the push rod so that the nut adjusting member can be moved back and forth while the push rod moves forward and backward according to the rotation direction of the rotating shaft. It is configured to be.

이하, 본 발명에 따른 하나의 바람직한 실시 예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.
