이러한 브레이크 시스템 중 전자 제어되는 모터를 동력원으로 하여 제동력을 발생시키는 전자 브레이크 시스템(EMB, Electro - Mechanical Brake)은, 유압을 이용해 제동력을 발생하지 않으므로 유압식 브레이크에 비해 구성의 단순화와 더불어, 여러 전자 제어 장치와 함께 통합 섀시 제어를 최적으로 구현할 수 있는 브레이크 시스템으로서 주목받고 있다.Among these brake systems, an electronic brake system (EMB, Electro - Mechanical Brake) that generates a braking force by using an electronically controlled motor as a power source does not generate a braking force by using hydraulic pressure, so that the system is simpler in configuration than a hydraulic brake, And has been attracting attention as a brake system capable of optimally implementing integrated chassis control together with the apparatus.

전자 브레이크 시스템(EMB)은 제동 시, 액추에이터를 통해 작동되는 웨지 조립체의 자기 배력(Self-Energizing)작용 즉, 액추에이터의 구동에 따라 웨지가 이동해 패드를 가압함과 더불어 패드와 디스크간 마찰력이 추가적인 입력으로 작용하게 되고, 이러한 웨지 작용으로 모터 사양에 비해 보다 큰 제동력을 구현 할 수 있게 된다.In the electronic brake system (EMB), during the braking operation, the self-energizing action of the wedge assembly operated through the actuator, that is, the wedge moves according to the driving of the actuator to press the pad, And the wedge action can realize a greater braking force than the motor specification.

FIG. 1 is a view schematically showing a state in which a disc and a pad are spaced apart from each other in an electromagnetic brake apparatus according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of an electromagnetic brake apparatus according to an embodiment of the present invention, FIG. 3 is a view schematically showing a state in which the pressing force of the pad portion is maintained by the parking holding portion in the electromagnetic brake device according to the embodiment of the present invention, and FIG. 4 is a cross- 1 is a view schematically showing a parking holding portion in an electromagnetic braking device according to an embodiment of the present invention.

도 1 내지 도 4를 참조하면, 본 발명의 일 실시예에 따른 전자 브레이크 장치(1)에는 하우징부(10), 모터부(20), 모터구동부(30), 나사부(40), 패드부(50) 및 파킹유지부(60)가 구비된다.1 to 4, the electromagnetic brake unit 1 according to an embodiment of the present invention includes a housing unit 10, a motor unit 20, a motor driving unit 30, a screw unit 40, a pad unit 50 and a parking holding portion 60 are provided.

하우징부(10)는 차체(미도시)에 장착된다. 이러한 하우징부(10)의 내부에는 설치공간(11)이 형성된다.The housing portion 10 is mounted on a vehicle body (not shown). An installation space 11 is formed in the housing part 10.

모터부(20)는 하우징부(10)에 구비된다. 이러한 모터부(20)는 전원이 인가됨에 따라 구동되어 모터구동부(30)를 회전시킨다.The motor unit 20 is provided in the housing unit 10. The motor unit 20 is driven as the power is applied to rotate the motor driving unit 30.

모터구동부(30)는 설치공간(11)에 위치되고, 모터부(20)의 구동력을 나사부(40)에 전달한다.The motor driving portion 30 is located in the installation space 11 and transfers the driving force of the motor portion 20 to the screw portion 40.

나사부(40)는 하우징부(10)에 형성되는 나사홀부(13)를 관통하여 하우징부(10)의 외부로 돌출된다. The threaded portion 40 penetrates the threaded hole portion 13 formed in the housing portion 10 and protrudes outside the housing portion 10.

패드부(50)는 나사부(40)에 연결되며, 나사부(40)의 회전방향에 따라 디스크(110)에 밀착되거나 디스크(110)에서 이격된다. The pad portion 50 is connected to the threaded portion 40 and is brought into close contact with the disc 110 or spaced apart from the disc 110 according to the rotational direction of the threaded portion 40.

예를 들어, 패드부(50)는 나사부(40)와 나사 결합되고, 지지대(미도시)에 의해 회전이 제한되면, 나사부(40)가 일방향으로 회전되는 경우 패드부(50)는 디스크(110)에 밀착되고, 나사부(40)가 타방향으로 회전되는 경우 패드부(50)는 디스크(110)에서 이격된다.For example, if the pad portion 50 is screwed to the threaded portion 40 and rotation of the threaded portion 40 is restricted by the support (not shown), when the threaded portion 40 is rotated in one direction, And when the screw portion 40 is rotated in the other direction, the pad portion 50 is separated from the disk 110. [

한편, 나사부(40)는 나사홀부(13)에 나사 결합되어도 무방하며, 이 경우에는 나사부(40)의 회전방향에 따라 나사부(40)가 하우징부(10)의 외부로 돌출되거나 하우징부(10) 내부로 삽입되어 패드부(50)와 디스크(110) 간의 거리를 조절한다.In this case, the threaded portion 40 may protrude out of the housing portion 10 in accordance with the rotation direction of the threaded portion 40, or the threaded portion 40 may protrude from the housing portion 10 And the distance between the pad unit 50 and the disk 110 is adjusted.

파킹유지부(60)는 하우징부(10)에 구비되고, 모터구동부(30)의 회전을 선택적으로 제한한다. 즉, 파킹유지부(60)는 나사부(40)의 회전에 의해 패드부(50)가 디스크(110)에 밀착된 상태에서 모터구동부(30)의 회전을 제한함으로써, 모터부(20)에 공급되는 전원이 차단되더라도 패드부(50)가 디스크(110)에 밀착된 상태를 유지시킨다.The parking holding portion 60 is provided in the housing portion 10 and selectively restricts the rotation of the motor driving portion 30. [ That is, the parking holding portion 60 limits the rotation of the motor driving portion 30 in a state where the pad portion 50 is in close contact with the disk 110 by the rotation of the screw portion 40, The pad unit 50 maintains a state in which the pad unit 50 is in close contact with the disk 110 even if the power source is shut off.

본 발명의 일 실시예에 따른 모터구동부(30)에는 구동축(31)과 구동기어(32)가 구비된다. The motor driving unit 30 according to an embodiment of the present invention includes a driving shaft 31 and a driving gear 32.

구동축(31)은 모터부(20)에 일단부가 연결되고 나사부(40)에 타단부가 연결된다. 이러한 구동축(31)은 모터부(20)의 구동력에 의해 회전되어 궁극적으로 나사부(40)를 회전시킨다.One end of the drive shaft 31 is connected to the motor unit 20 and the other end of the drive shaft 31 is connected to the screw 40. The drive shaft 31 is rotated by the driving force of the motor unit 20 to ultimately rotate the threaded portion 40.

구동기어(32)는 구동축(31)에 구비된다. 이러한 구동기어(32)는 원판 형상을 하며 외주면에 치열이 형성되고, 구동축(31)과 연동되어 회전된다.The drive gear 32 is provided on the drive shaft 31. The drive gear 32 has a disk shape and is formed with teeth on the outer circumferential surface thereof, and rotates in conjunction with the drive shaft 31.

본 발명의 일 실시예에 따른 파킹유지부(60)에는 리프터(61), 가변축(62), 파킹기어(63) 및 파킹레버(64)가 구비된다.The parking pawl 60 is provided with a lifter 61, a variable shaft 62, a parking gear 63, and a parking lever 64 in accordance with an embodiment of the present invention.

리프터(61)는 하우징부(10)에 구비되고, 가변축(62)은 리프터(61)에 연결된다. 리프터(61)는 제어신호에 의해 구동되어 가변축(62)을 이동시키는 것으로서 솔레노이드가 사용된다. The lifter 61 is provided in the housing portion 10 and the variable shaft 62 is connected to the lifter 61. The lifter 61 is driven by a control signal to move the variable shaft 62, and a solenoid is used.

가변축(62)은 리프터(61)에 의해 길이가 가변되는 것으로서, 일단부가 리프터(61)에 회전 가능하도록 결합되고, 타단부가 하우징부(10)의 가이드홈(12)에 삽입된다.One end of the variable shaft 62 is connected to the lifter 61 so as to be rotatable and the other end of the variable shaft 62 is inserted into the guide groove 12 of the housing portion 10.

파킹기어(63)는 가변축(62)에 구비된다. 이러한 가변축(62)은 원판 형상을 하며 외주면에 치열이 형성되어 구동기어(32)와 맞물린다.The parking gear 63 is provided on the variable shaft 62. The variable shaft 62 is in the shape of a disk and is formed with teeth on the outer circumferential surface to engage with the driving gear 32.

파킹레버(64)는 가변축(62)에 구비되고 측방향으로 돌출 형성되어 스토퍼(65)에 걸린다. 리프터(61)의 구동으로 가변축(62)의 길이가 늘어나면 파킹레버(64)와 스토퍼(65)가 수평선상에 위치되어 파킹레버(64)의 회전이 제한되도록, 스토퍼(65)는 하우징부(10)의 설치공간(11)에 위치된다.
The parking lever 64 is provided on the variable shaft 62 and protrudes laterally so as to be caught by the stopper 65. When the length of the variable shaft 62 is increased by driving the lifter 61, the parking lever 64 and the stopper 65 are positioned on the horizontal line so that the rotation of the parking lever 64 is restricted. (10).

상기와 같은 구조를 갖는 본 발명의 일 실시예에 따른 전자 브레이크 장치의 작용을 설명하면 다음과 같다.Hereinafter, the operation of the electromagnetic brake apparatus according to the embodiment of the present invention will be described.

패드부(50)와 디스크(110)가 이격된 상태에서(도 1 참조), 주차신호가 모터부(20)와 리프터(61)에 전달되면, 모터부(20)가 구동되어 구동축(31)은 일방향으로 회전되고, 이와 연결된 나사부(40)는 동일 방향으로 회전된다.When the parking signal is transmitted to the motor unit 20 and the lifter 61 in a state where the pad unit 50 and the disk 110 are separated from each other (see FIG. 1), the motor unit 20 is driven, And the threaded portions 40 connected thereto are rotated in the same direction.

나사부(40)가 회전됨에 따라 패드부(50)는 디스크(110)에 밀착된다(도 2 참조). 이때, 나사부(40)와 연동되어 구동축(31)이 회전되고, 구동축(31)에 구비되는 구동기어(32)는 파킹기어(63)와 맞물린 상태에서 회전된다.As the threaded portion 40 is rotated, the pad portion 50 is brought into close contact with the disk 110 (see FIG. 2). At this time, the drive shaft 31 is rotated by interlocking with the threaded portion 40, and the drive gear 32 provided on the drive shaft 31 is rotated while being engaged with the parking gear 63.

상기한 상태에서, 리프터(61)의 구동으로 가변축(62)의 길이가 늘어나 파킹레버(64)가 이동되어 스토퍼(65)와 수평선상에 위치된다(도 3 참조).In this state, the length of the variable shaft 62 is increased by the driving of the lifter 61, and the parking lever 64 is moved and positioned on the horizontal line with the stopper 65 (see FIG. 3).

따라서, 모터부(20)의 전원공급이 차단되더라도 구동기어(32)와 파킹기어(63)가 맞물려있고, 가변축(62)에 구비되는 파킹레버(64)가 스토퍼(65)에 걸림고정됨으로써, 나사부(40)의 타방향 회전이 방지되어 패드부(50)와 디스크(110)의 밀착상태가 유지된다.
The drive gear 32 and the parking gear 63 are meshed with each other and the parking lever 64 provided on the variable shaft 62 is engaged and fixed to the stopper 65 even when the power supply to the motor unit 20 is interrupted , Rotation of the threaded portion 40 in the other direction is prevented, and the contact state of the pad portion 50 and the disk 110 is maintained.
