Description

차량용 디스크 브레이크{DISK BRAKE FOR VEHICLE}Car Disc Brake {DISK BRAKE FOR VEHICLE}

본 발명은 차량용 디스크 브레이크에 관한 것으로, 더욱 상세하게는 쐐기 형태로 형성된 쐐기부재를 통해 마찰패드를 디스크 쪽으로 가압하는 차량용 디스크 브레이크에 관한 것이다.The present invention relates to a vehicle disk brake, and more particularly to a vehicle disk brake for pressing the friction pad toward the disk through a wedge member formed in the shape of a wedge.

디스크 브레이크는 휠과 함께 회전하는 디스크의 외면을 마찰패드로 가압하여 제동력을 얻는 장치이다. 디스크 브레이크의 중에는 빗면 슬라이드 방식의 쐐기부재를 이용하여 마찰패드를 디스크 쪽으로 가압하는 방식이 있다. 예컨대, 쐐기부재가 구동장치의 구동에 의해 빗면을 따라 밀리면서 마찰패드를 디스크 쪽으로 가압하는 방식이다. Disc brake is a device that obtains a braking force by pressing the outer surface of the disk rotating with the wheel with a friction pad. Among the disc brakes, there is a method of pressing the friction pad toward the disc by using a wedge member of the inclined slide type. For example, the wedge member pushes the friction pad toward the disk while being pushed along the inclined surface by the driving device.

쐐기 방식의 차량용 디스크 브레이크(Electronic Wedge Brake, EWB)는 쐐기부재를 동작시키는 구동모터와, 구동모터의 회전축에 결합된 나사축과, 구동모터의 동작에 의해 디스크와 평행한 방향으로 진퇴하도록 나사축에 결합되는 쐐기부재와, 쐐기부재와 대응하는 형태로 형성되어 쐐기부재를 디스크 쪽으로 가압하는 쐐기부가 형성된 캘리퍼 하우징을 포함한다. Wedge-type vehicle disc brakes (Electronic Wedge Brake, EWB) have a drive motor for operating the wedge member, a screw shaft coupled to the rotation shaft of the drive motor, and a screw shaft to retreat in a direction parallel to the disc by the operation of the drive motor. And a caliper housing formed with a wedge member coupled to the wedge member and having a wedge portion formed to correspond to the wedge member to press the wedge member toward the disc.

이러한 디스크 브레이크는 구동모터가 동작하여 쐐기부재를 일방향으로 이동 시키면, 마찰패드와 디스크의 접촉이 이루어짐과 동시에 쐐기부재가 쐐기부의 빗면을 따라 밀리면서 마찰패드를 더욱 디스크 쪽으로 가압함으로써 제동이 이루어지도록 한다.Such a disc brake causes the drive motor to move the wedge member in one direction, thereby making contact with the friction pad and the disc, and simultaneously pushing the friction pad toward the disc while pushing the wedge member along the inclined surface of the wedge. .

그런데, 이러한 종래의 차량용 디스크 브레이크는 주행 시 발생하는 진동 등에 의해 디스크와 쐐기부재 사이의 간격이 충분이 확보되지 않은 상태에서 디스크와 쐐기부재 사이의 수분이나 기타 이물질로 인해 점착성이 생긴 경우, 디스크의 회전에 따라 마찰패드가 디스크에 의해 디스크의 회전방향으로 끌려들어가게 되고, 그에 따라 의도하지 않은 제동이 발생할 수 있다는 문제점이 있다. However, such a conventional disc brake for a vehicle has a stickiness due to moisture or other foreign matter between the disc and the wedge member in a state where the gap between the disc and the wedge member is not secured due to vibration generated during driving, or the like. The friction pad is dragged by the disk in the rotational direction of the disk according to the rotation, and thus there is a problem that unintended braking may occur.

본 발명은 상술한 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 의도하지 않게 마찰패드가 디스크에 의해 디스크의 회전방향으로 끌려들어가는 것을 방지할 수 있는 차량용 디스크 브레이크를 제공하는 것이다. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a disc brake for a vehicle which can prevent the friction pad from being unintentionally drawn in the rotational direction of the disc by the disc.

상술한 본 발명의 목적을 달성하기 위한 본 발명에 따른 차량용 디스크 브레이크는 차량의 휠과 함께 회전하는 디스크와, 상기 디스크의 양측에 배치된 이너 마찰패드 및 아웃터 마찰패드와, 상기 이너 마찰패드 및 상기 아웃터 마찰패드 배면 쪽에 각각 설치되는 이너 쐐기부재 및 아웃터 쐐기부재와, 상기 이너 쐐기부재를 이동시키기 위한 동력을 발생시키는 구동장치와, 상기 구동장치로부터 동력을 전달받아 이동하며 상기 이너 쐐기부재를 이동시키는 이동 가이드와, 상기 이동 가 이드와 상기 이너 쐐기부재를 선택적으로 락킹하여 함께 이동하도록 하는 락킹장치를 포함한다. Disc brake for a vehicle according to the present invention for achieving the above object of the present invention, a disk that rotates with the wheel of the vehicle, inner friction pads and outer friction pads disposed on both sides of the disk, the inner friction pad and the An inner wedge member and an outer wedge member respectively installed on the rear side of the outer friction pad, a driving device for generating power for moving the inner wedge member, and receiving power from the driving device to move the inner wedge member. It includes a movement guide, and a locking device for selectively locking the movement guide and the inner wedge member to move together.

또한, 상기 락킹장치는 진퇴이동 가능하게 설치되어 상기 이동 가이드로부터 돌출되며 상기 이너 쐐기부재에 걸리는 락킹부재와, 상기 락킹부재를 돌출시키는 액추에이터를 포함한다. The locking device may include a locking member protruding from the moving guide and being caught by the inner wedge member and an actuator protruding from the locking member.

또한, 상기 이동 가이드에는 상기 락킹부재가 수용되는 수용홈이 마련되며, 상기 이너 쐐기부재에는 상기 수용홈으로부터 돌출된 상기 락킹부재가 진입하여 걸리는 락킹홈이 마련된다. In addition, the movement guide is provided with a receiving groove for accommodating the locking member, and the inner wedge member is provided with a locking groove for the locking member protruding from the receiving groove to enter.

또한, 상기 액추에이터는 솔레노이드를 포함한다. The actuator also includes a solenoid.

상술한 바와 같이 본 발명에 따른 차량용 디스크 브레이크는 제동이 가해질 경우에만 락킹장치에 의해 이동 가이드와 쐐기부재가 서로 락킹되어 쐐기부재가 이동 가이드와 함께 이동하게 되므로, 의도하지 않은 제동이 발생하는 것을 예방할 수 있게 되는 효과가 있다. As described above, the vehicle disc brake according to the present invention locks the movement guide and the wedge member to each other by the locking device only when braking is applied, so that the wedge member moves together with the movement guide, thereby preventing unintended braking. There is an effect that becomes possible.

The movement guide 65 is provided with an accommodating groove 65c in which the locking member 71 is accommodated, and an inner wedge member 30 with a locking groove in which the locking member 71 protruding from the accommodating groove 65c is inserted. 30c) is provided concave. In this embodiment, the actuator 72 is made of a solenoid.

따라서, 평상시에는 도 3에 도시한 바와 같이 락킹부재(71)가 수용홈(65c)에 수용되어 이동 가이드(65)와 이너 쐐기부재(30)가 서로 분리되어 있는 상태를 유지하다가, 제동이 이루어질 경우에는 도 4에 도시한 바와 같이 액추에이터(72)에 전원을 인가하여 락킹부재(71)가 수용홈(65c)으로부터 돌출되어 락킹홈(30c) 내로 진입하도록 함으로써, 이너 쐐기부재(30)와 이동 가이드(65)를 락킹부재(71)를 통해 락킹하여 이너 쐐기부재(30)가 이동 가이드(65)와 함께 이동할 수 있도록 하는 것이다. Therefore, as shown in FIG. 3, the locking member 71 is accommodated in the receiving groove 65c to maintain the state in which the movement guide 65 and the inner wedge member 30 are separated from each other, and then braking is performed. In this case, as shown in FIG. 4, by applying power to the actuator 72, the locking member 71 protrudes from the accommodation groove 65c and enters the locking groove 30c, thereby moving with the inner wedge member 30. Locking the guide 65 through the locking member 71 is to allow the inner wedge member 30 to move with the movement guide (65).

또한, 상술한 바와 같이 락킹장치(70)를 통해 필요에 따라 이동 가이드(65)와 이너 쐐기부재(30)를 분리하거나 이동 가이드(65)와 이너 쐐기부재(30)를 락킹할 수 있으므로, 의도하지 않게 제동이 발생하는 것을 방지할 수 있다. In addition, as described above, the locking guide 70 can separate the moving guide 65 and the inner wedge member 30 or lock the moving guide 65 and the inner wedge member 30 as necessary. It is possible to prevent braking from occurring.

본 실시예에서 액추에이터(72)는 솔레노이드로 이루어져 있으나 이에 한정하지 않고, 모터 등 락킹부재(71)를 진퇴이동 시킬 수 있는 다양한 종류의 구동장치들이 모두 액추에이터(72)로 사용되어질 수 있다. In this embodiment, the actuator 72 is made of a solenoid, but not limited thereto, and various kinds of driving devices capable of moving forward and backward of the locking member 71 such as a motor may be used as the actuator 72.
