본 발명은 원격 조절되는 모터를 이용하여 이퀄라이저를 동작시키는 전자식 주차 브레이크에 관한 것이다. The present invention relates to an electronic parking brake for operating an equalizer using a remotely controlled motor.

종래, 기계식 주차 브레이크로서, 예컨대 한국특허공개 제2002-35957호의 공보에 개시된 것이 제안되어 있다. 이 기계식 주차 브레이크는, 도 1에 도시한 바와 같이, 제1지지부재(12)와 제2지지부재(14) 사이에 회동 가능하게 지지되는 회전축 (16)에 고정되는 조작레버(10)와 암(18), 이 암(18)의 일측과 이퀄라이저(24)에 결합되는 와이어로드(20)와, 이 와이어로드(20)의 일단에 결합되어 회전에 따라 이퀄라이저(24)를 와이어로드(20)의 축방향으로 이동시킴으로써 와이어(22)의 유격을 조절하는 너트(26)를 포함하여 구성된다. Conventionally, as a mechanical parking brake, for example, what is disclosed in Korean Patent Laid-Open No. 2002-35957 has been proposed. As shown in FIG. 1, the mechanical parking brake has an operating lever 10 and an arm fixed to a rotating shaft 16 that is rotatably supported between the first support member 12 and the second support member 14. 18, a wire rod 20 coupled to one side of the arm 18 and the equalizer 24, and a wire rod 20 coupled to one end of the wire rod 20 to rotate the equalizer 24 according to rotation. It comprises a nut 26 for adjusting the play of the wire 22 by moving in the axial direction of.

이와 같은 기계식 주차 브레이크에서는 운전석 옆에 조작레버(10)가 배치되어 실내 공간을 차지할 뿐 아니라, 운전석까지 와이어가 연결되어야 하는 장착 불편 등의 트러블이 있다. In such a mechanical parking brake, the operation lever 10 is disposed beside the driver's seat to occupy the interior space, and there is a trouble such as a mounting inconvenience that a wire must be connected to the driver's seat.

본 발명은 전술한 문제를 해결하기 위하여 안출된 것으로, 설치 공간을 최소화하고 와이어 장착 불편을 해소할 수 있는 구조를 갖는 전자식 주차 브레이크를 제공함에 그 목적이 있다. The present invention has been made to solve the above-described problem, and an object thereof is to provide an electronic parking brake having a structure that can minimize the installation space and eliminate wire mounting inconvenience.

전술한 목적을 달성하기 위한 본 발명의 전자식 주차 브레이크는 양측에 와이어가 설치되는 평판형 이퀄라이저; 원격 조절용 케이블에 접속되는 모터; 상기 모터의 회전운동을 전달받아 상기 이퀄라이저를 작동하는 작동기구를 포함하여 이루어진다. Electronic parking brake of the present invention for achieving the above object is a flat type equalizer, the wire is installed on both sides; A motor connected to the remote control cable; It includes an operating mechanism for receiving the rotational movement of the motor to operate the equalizer.

이 구성에 의하면, 설치 공간을 최소화하고 와이어 장착 불편을 해소할 수 있다. According to this structure, installation space can be minimized and the wire mounting inconvenience can be eliminated.

전술한 구성에서, 상기 작동기구는 상기 모터의 회전축에 형성되는 워엄; 상기 워엄과 맞물리는 워엄 휠; 상기 워엄 휠의 보스에 형성되는 암나사부; 일단은 상기 이퀄라이저에 결합된 채 상기 암나사부에 체결되는 스크루봉으로 구성되는 것이 바람직하다. In the above-described configuration, the operating mechanism is a worm formed on the rotating shaft of the motor; A worm wheel engaged with the worm; A female screw portion formed on the boss of the worm wheel; One end is preferably composed of a screw rod coupled to the female screw portion coupled to the equalizer.

또한, 상기 워엄 휠이 헬리컬 기어로 구현되면, 모터의 회전축에 걸리는 추력을 감소시켜 모터의 내구성을 향상시킬 수 있다. In addition, when the worm wheel is implemented as a helical gear, it is possible to improve the durability of the motor by reducing the thrust applied to the rotation axis of the motor.

한편, 상기 회전축에 스플라인 결합될 풀리(pulley)가 더 배치되면, 모터가 작동하지 않는 경우 수동으로 이퀄라이저를 동작시킬 수 있다. Meanwhile, when a pulley to be splined to the rotation shaft is further disposed, the equalizer may be manually operated when the motor does not operate.

이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 설명하는데, 종래의 것과 동일한 부분에 대해서는 동일한 참조부호를 부여하고 상세한 설명은 생략한다. Best Mode for Carrying Out the Invention Preferred embodiments of the present invention will now be described with reference to the accompanying drawings, where like reference numerals are used to designate like parts, and detailed description thereof will be omitted.

도 2는 본 발명의 바람직한 실시예에 따른 전자식 주차 브레이크를 도시한 사시도이다. 도 2에 도시한 바와 같이, 본 실시예의 전자식 주차 브레이크는 이퀄라이저(24), 모터(110), 이퀄라이저(24)와 모터(110) 사이에 개재되는 이퀄라이저작동기구(130)로 구성되어 있다. 2 is a perspective view illustrating an electronic parking brake according to a preferred embodiment of the present invention. As shown in FIG. 2, the electronic parking brake of the present embodiment is composed of an equalizer 24, a motor 110, an equalizer operating mechanism 130 interposed between the equalizer 24 and the motor 110.

이퀄라이저(24)는 평판형으로서 양측에 와이어(22)가 장착되어 있다. The equalizer 24 is flat and the wires 22 are attached to both sides.

모터(110)는 운전자가 버튼 등의 스위치에 의해 구동 제어할 수 있다. 이 모터(110)는 기계식 레버에 비해 전자 제어(예컨대, ECU)를 통한 다양한 기능을 확장할 수 있다. The motor 110 may be controlled by the driver by a switch such as a button. The motor 110 can extend various functions through electronic control (eg ECU) compared to mechanical levers.

이퀄라이저작동기구(130)는 모터(110)의 회전축(111)에 형성되는 워엄(131)과, 워엄(131)과 맞물리는 워엄 휠(133), 워엄 휠(133)의 보스(135)에 형성되는 암나사부(미도시), 일단은 이퀄라이저(24)의 중심에 결합된 채 상기 암나사부에 체결 되는 스크루봉(137)으로 구성되어 있다. The equalizer operating mechanism 130 is formed on the worm 131 formed on the rotary shaft 111 of the motor 110, the worm wheel 133 meshing with the worm 131, and the boss 135 of the worm wheel 133. Being female screw portion (not shown), one end is composed of a screw rod 137 coupled to the female screw portion while being coupled to the center of the equalizer 24.

워엄(131)과 워엄 휠(133)의 채택 결합은, 와이어(22)의 당김 방향을 모터(110)의 회전축(111)과 직각으로 형성시킨다. 이 배치 구조로 인해, 모터에 추력(와이어 당기는 힘의 반력)이 직접적으로 전달되지 않아, 모터 보호 차원에서 유리하다. 또한, 스크루봉(137)과 암나사부의 채택 결합은 스크루봉(137)의 직선운동을 정밀하고 정확하게 구동시킬 수 있다. 이 직선운동을 보다 확실히 행하기 위해서는 와이어(120), 평판형 이퀄라이저(100) 또는 스크루봉(137)의 회전을 방지하는 가이드를 두면 좋다. Adoption coupling of the worm 131 and the worm wheel 133 forms the pulling direction of the wire 22 at right angles with the rotation shaft 111 of the motor 110. Due to this arrangement structure, thrust (reaction force of wire pulling force) is not transmitted directly to the motor, which is advantageous in terms of motor protection. In addition, the adoption of the screw rod 137 and the female threaded portion can accurately and accurately drive the linear motion of the screw rod 137. In order to perform this linear motion more reliably, the guide which prevents rotation of the wire 120, the flat plate type equalizer 100, or the screw rod 137 may be provided.

이와 같은 구성에 의하여, 차 실내에 조작레버를 설치할 필요가 없고, 운전석까지 주차 와이어를 연결할 필요가 없게 된다. By such a configuration, there is no need to install an operation lever in the car interior, and there is no need to connect the parking wire to the driver's seat.

한편, 워엄 휠(133)은 헬리컬 기어로 구현하는 것이 바람직하다. 헬리컬 기어는 스퍼 기어보다 물림율이 좋아 소음 진동이 작아서 모터(110)나 이퀄라이저작동기구(130)의 내구성을 높일 수 있다. On the other hand, the worm wheel 133 is preferably implemented by a helical gear. Since the helical gear has a better bite rate than the spur gear, the vibration of the noise is small, thereby increasing the durability of the motor 110 or the equalizer operating mechanism 130.

이와 같이 구성된 본 실시예의 작동을 설명한다. The operation of this embodiment configured as described above will be described.

모터(110)에 전원이 인가되면 회전축(111)이 정회전하고, 이 정회전에 의해 워엄(131)과 워엄 휠(133)도 회전하게 된다. 워엄 휠(133)의 회전은 암나사부에 나사 체결된 스크루봉(137)이 직선 운동한다. 이 직선 운동에 의해, 이퀄라이저(24)를 통해 주차 브레이크의 와이어(22)를 당겨 주차 브레이크를 작동한다. 브레이크 해제는 모터(110)의 회전축(111)을 역회전하면 된다. When power is applied to the motor 110, the rotation shaft 111 rotates forward, and the worm 131 and the worm wheel 133 also rotate by this forward rotation. The rotation of the worm wheel 133 is a linear movement of the screw rod 137 screwed to the female thread portion. By this linear motion, the parking brake wire is pulled through the equalizer 24 to operate the parking brake. The brake may be reversely rotated by the rotation shaft 111 of the motor 110.

한편, 모터(110)에 전원이 인가되지 않는 비상상황이 생길 수 있다. 특히 언 덕길에 주차할 경우 더욱 그렇다. 이 비상상황에서 회전축(111)의 선단에 스플라인축을 형성하고, 이 스플라인축에 결합되는 스플라인을 갖는 풀리(pulley)가 배치되며, 운전자는 회전축에 풀리를 결합한 후 풀리에 와이어나 로프를 감아 돌리면 전술한 바와 같이 작동시킬 수 있다. On the other hand, an emergency may occur in which power is not applied to the motor 110. This is especially true when parking on hillsides. In this emergency, a spline shaft is formed at the tip of the rotating shaft 111, and a pulley having a spline coupled to the spline shaft is disposed, and the driver combines the pulley with the rotating shaft and winds a wire or rope around the pulley to tactically. Can be operated as one.
