차량 주행 중에 운전자가 브레이크페달(30)을 밟으면 브레이크페달(30)이 회전되면서 브레이크페달(30)의 조작여부 또는 조작정도에 따라 모터(50)가 구동되어 볼트부재(76)가 회전된다.When the driver presses the brake pedal 30 while the vehicle is running, the brake pedal 30 is rotated, and the motor 50 is driven in accordance with whether the brake pedal 30 is operated or operated, and the bolt member 76 is rotated.

볼트부재(76)가 회전되면 볼트부재(76)와 볼트결합되는 너트부재(77)가 본체(10)를 따라 슬라이딩되면서 차륜에 제동력을 제공하는 압력을 생성하게 된다.When the bolt member 76 is rotated, the nut member 77, which is bolted to the bolt member 76, slides along the body 10 to generate a pressure that provides the braking force to the wheel.

너트부재(77)는 본체(10)에 슬라이딩 가능하게 설치되기 때문에 볼트부재(76)가 회전될 때에 본체(10)의 나사산의 회전운동에 의해 본체(10)를 따라 전진 또는 후진하게 된다.The nut member 77 is slidably installed on the main body 10 so that the bolt member 76 is moved forward or backward along the main body 10 by rotating the thread of the main body 10 when the bolt member 76 is rotated.

이때, 볼트부재(76)와 너트부재(77)가 억지끼움되는 잠김현상이 발생될 수 있는데, 본 실시예는 잠김방지부(80)의 작동에 의해 볼트부재(76)와 너트부재(77)가 잠기는 것을 방지할 수 있게 된다.At this time, a locking phenomenon may be generated in which the bolt member 76 and the nut member 77 are inhibited.

커넥터(74)는 캡 모양으로 형성되고, 외벽에 샤프트(72)가 연결되고, 커넥터(74)의 내벽에는 볼트부재(76)의 단부가 연결된다.The connector 74 is formed in a cap shape, a shaft 72 is connected to the outer wall, and an end of the bolt member 76 is connected to the inner wall of the connector 74.

잠김방지부(80)는, 커넥터(74)에 설치되고 너트부재(77)가 접촉되는 트러스트베어링(82)과, 트러스트베어링(82)과 너트부재(77) 사이에 개재되는 C링(84)을 포함한다.The lock preventing portion 80 includes a thrust bearing 82 which is provided on the connector 74 and to which the nut member 77 contacts and a C ring 84 which is interposed between the thrust bearing 82 and the nut member 77, .

트러스트베어링(82)은 복수 개의 패널이 회전 가능하게 연결되고, 복수 개의 패널 사이에 완충부재가 개재되는 장치이며, 트러스트베어링(82)은 본 발명의 기술구성을 인지한 당업자가 용이하게 실시할 수 있는 것이므로 구체적인 도면이나 설명은 생략하기로 한다.The thrust bearing 82 is a device in which a plurality of panels are rotatably connected and a buffer member is interposed between a plurality of panels. The thrust bearing 82 can be easily carried out by a person skilled in the art The detailed drawings and explanations thereof will be omitted.

볼트부재(76)의 나사산을 따라 슬라이딩되는 너트부재(77)가 밀착되면 트러스트베어링(82)이 트러스트되면서 너트부재(77)와 트러스트베어링(82) 사이의 충격을 완충시키게 되므로 제동작동 중에 발생되는 소음을 저감시키게 된다.The nut member 77 sliding along the thread of the bolt member 76 is tightened so that the thrust bearing 82 is relieved and the impact between the nut member 77 and the thrust bearing 82 is buffered. Thereby reducing noise.

또한, 트러스트베어링(82)은 너트부재(77)가 커넥터(74) 내측으로 이동될 때에 너트부재(77)와 커넥터(74) 내벽 사이에 개재되므로 너트부재(77)가 커넥터(74)의 내벽에 밀착되어 볼트부재(76)와 잠기는 것을 방지하게 된다.Since the nut member 77 is interposed between the nut member 77 and the inner wall of the connector 74 when the nut member 77 is moved to the inside of the connector 74, So that it is prevented from being locked with the bolt member 76.

또한, 너트부재(77)와 트러스트베어링(82) 사이에는 C링(84)이 개재되므로 너트부재(77)와 트러스트베어링(82) 사이에 접촉이 반복되면서 트러스트베어링(82)이 마모되거나 파손되는 것을 방지할 수 있게 된다.Since the C ring 84 is interposed between the nut member 77 and the thrust bearing 82, the contact between the nut member 77 and the thrust bearing 82 is repeated and the thrust bearing 82 is worn or damaged .

미설명 부호 70은 샤프트(72), 커넥터(74), 볼트부재(76), 너트부재(77) 및 가이드부재(78)를 포함하는 동력전달부(70)이다.
The reference numeral 70 is a power transmitting portion 70 including a shaft 72, a connector 74, a bolt member 76, a nut member 77, and a guide member 78.

상기와 같이 구성된 본 발명의 일 실시예에 따른 차량용 제동장치의 작동을 살펴보면 다음과 같다.The operation of the braking system for a vehicle according to an embodiment of the present invention will now be described.

차량 주행 중에 운전자가 브레이크페달(30)을 조작하면 제1실린더(34)가 슬라이딩되면서 압력을 생성하고, 제1실린더(34)에 의해 생성되는 압력이 모사실린더(96)에 전달되면서 제1압력센서(98)에 의해 브레이크페달(30)의 작동력이 측정된다.When the driver operates the brake pedal 30 while the vehicle is running, the first cylinder 34 slides to generate pressure, and the pressure generated by the first cylinder 34 is transmitted to the simulation cylinder 96, The operating force of the brake pedal 30 is measured by the sensor 98. [

이때, 제1실린더(34)와 모사실린더(96) 사이의 유로에 설치되는 제1스위치(92)는 개방되고, 제1실린더(34)와 제2실린더(14)를 연결하는 유로에 설치되는 제2스위치(94)는 차단되므로 제1실린더(34)에 의해 발생되는 압력은 모사실린더(96) 측으로 공급된다.At this time, the first switch 92 provided in the flow path between the first cylinder 34 and the simulation cylinder 96 is opened and installed in the flow path connecting the first cylinder 34 and the second cylinder 14 Since the second switch 94 is shut off, the pressure generated by the first cylinder 34 is supplied to the simulating cylinder 96 side.

본체(10)에 설치되는 스트로크센서(32)에 의해 브레이크페달(30)의 회전량을 감지할 수 있으므로 제1압력센서(98) 및 스트로크센서(32)에서 송신되는 신호에 따라 제어부에서 브레이크페달(30)의 조작여부 및 조작정도를 판단하게 된다.The amount of rotation of the brake pedal 30 can be sensed by the stroke sensor 32 provided in the main body 10 and the brake pedal 30 can be detected by the control unit in accordance with the signal transmitted from the first pressure sensor 98 and the stroke sensor 32. [ (30) and the degree of operation.

이후에, 제어부에서 송신되는 작동신호에 따라 모터(50)가 구동되고, 모터(50)의 구동방향 및 구동정도에 따라 볼트부재(76)의 회전방향 및 회전량이 결정된다.Thereafter, the motor 50 is driven in accordance with the operation signal transmitted from the control unit, and the rotational direction and the rotational amount of the bolt member 76 are determined according to the driving direction and the driving degree of the motor 50.

모터(50)가 구동되면 모터(50)의 회전자에 연결되는 샤프트(72) 및 커넥터(74)가 회전되고, 커넥터(74)에 연결되는 볼트부재(76)가 회전되어 볼트부재(76)에 볼트결합되는 너트부재(77)가 슬라이딩된다.When the motor 50 is driven, the shaft 72 and the connector 74 connected to the rotor of the motor 50 are rotated and the bolt member 76 connected to the connector 74 is rotated to rotate the bolt member 76, The nut member 77 is slidably engaged with the nut member.

이때, 너트부재(77)는 본체(10)에 설치되는 가이드부재(78)를 따라 슬라이딩되며, 가이드부재(78)의 둘레면에는 직선 모양으로 긴 가이드홈부(78a)가 형성되고, 너트부재(77)에는 가이드홈부(78a)를 따라 슬라이딩 가능하도록 너트부재(77)의 둘레면에서 돌출되는 가이드돌기(77a)가 형성된다.At this time, the nut member 77 slides along a guide member 78 provided on the main body 10, and a guide groove 78a having a long linear shape is formed on the circumferential surface of the guide member 78, 77 are formed with guide projections 77a protruding from the circumferential surface of the nut member 77 so as to be slidable along the guide groove portion 78a.

가이드부재(78)를 따라 슬라이딩되는 너트부재(77)는 피스톤(79)을 가압하여 제2실린더(14) 및 제3실린더(16)를 가압하게 되므로 차륜의 제동력이 생성된다.The nut member 77 sliding along the guide member 78 presses the piston 79 to press the second cylinder 14 and the third cylinder 16 so that the braking force of the wheel is generated.

볼트부재(76) 및 가이드부재(78)를 따라 이동되는 너트부재(77)는 커넥터(74)의 내벽에 밀착되어 너트부재(77)와 볼트부재(76)가 억지결합될 수 있는데, 너트부재(77)가 커넥터(74) 측으로 이동되면 너트부재(77)와 커넥터(74) 사이에 C링(84) 및 트러스트베어링(82)이 개재되므로 너트부재(77)와 볼트부재(76)가 잠기는 것을 방지할 수 있게 된다.The nut member 77 moved along the bolt member 76 and the guide member 78 is brought into close contact with the inner wall of the connector 74 so that the nut member 77 and the bolt member 76 can be forcedly engaged, The nut member 77 and the bolt member 76 are locked because the C ring 84 and the thrust bearing 82 are interposed between the nut member 77 and the connector 74 when the pin member 77 is moved to the connector 74 side .

이로써, 제동작동 중에 발생되는 소음을 줄이고, 제동작동을 위한 동력전달이 차단되는 오작동을 방지할 수 있는 차량용 제동장치를 제공할 수 있게 된다.
Thereby, it is possible to provide a braking system for a vehicle that can reduce noise generated during braking operation and prevent malfunctions in which transmission of power for braking operation is interrupted.
