도 3은 본 발명의 일 실시예에 따른 차량의 주차 브레이크용 액추에이터가 도시된 구성도이고, 도 4는 본 발명의 일 실시예에 따른 차량의 주차 브레이크용 액추에이터의 볼트스크루 연결구조가 도시된 구성도이고, 도 5는 본 발명의 일 실시예에 따른 차량의 주차 브레이크용 액추에이터의 너트스크루 연결구조가 도시된 구성도이다.3 is a configuration diagram showing an actuator for a parking brake of a vehicle according to an embodiment of the present invention, Figure 4 is a configuration showing a bolt screw connection structure of the actuator for a parking brake of a vehicle according to an embodiment of the present invention 5 is a configuration diagram showing a nut screw connection structure of the actuator for a parking brake of a vehicle according to an embodiment of the present invention.

도 3 내지 도 5를 참조하면, 본 발명의 일 실시예에 따른 차량의 주차 브레이크용 액추에이터(50)는 케이스(52)와, 케이스(52)에 회전 가능하게 구비되는 볼트스크루(60)와, 볼트스크루(60)에 연결되는 모터(54)와, 케이스(52)에 직선운동 가능하게 설치되고, 볼트스크루(60)에 연결되는 너트스크루(70)와, 너트스크루(70)에 연결되어 케이스(52) 외부로 연장되는 주차케이블(80)을 포함한다.3 to 5, the parking brake actuator 50 of a vehicle according to an embodiment of the present invention includes a case 52, a bolt screw 60 rotatably provided at the case 52, The motor 54 connected to the bolt screw 60 and the case 52 are installed in a linear motion, and the nut screw 70 connected to the bolt screw 60 and the nut screw 70 are connected to the case. 52 includes a parking cable 80 extending to the outside.

이로써, 모터(54)가 구동되면 볼트스크루(60)가 회전되는데, 볼트스크루(60)는 회전운동 가능하지만 직선운동이 구속되게 설치되므로 볼트스크루(60)와 나사결합 되는 너트스크루(70)가 볼트스크루(60)를 따라 직선운동 하게 된다.Thus, when the motor 54 is driven, the bolt screw 60 is rotated, the bolt screw 60 is capable of rotational movement but since the linear motion is installed to be constrained, the nut screw 70 is screwed with the bolt screw 60 is The linear motion along the bolt screw (60).

이렇게 직선운동 되는 너트스크루(70)에 주차케이블(80)이 연결되기 때문에 주차케이블(80)을 당기는 인장력이 발생되거나 이 인장력이 해제되는 작동이 이루어지게 된다.Since the parking cable 80 is connected to the nut screw 70 that is linearly moved in this way, a pulling force is generated to pull the parking cable 80 or the tensioning force is released.

볼트스크루(60)에는 베어링(64)이 설치되어 케이스(52) 내부에 회전운동 가능하게 설치되는데, 볼트스크루(60)는 너트스크루(70)와 비교하여 직경이 작게 형성되므로 너트스크루(70)에 베어링(64)이 설치되는 종래 기술과 비교하면 베어링(64)이 작아지는 효과가 나타나게 된다.The bolt screw 60 is provided with a bearing 64 so as to be rotatable inside the case 52. The bolt screw 60 is formed with a smaller diameter compared to the nut screw 70, so that the nut screw 70 is provided. Compared with the prior art in which the bearing 64 is installed on the bearing 64, the bearing 64 becomes smaller.

너트스크루(70)는 단면 형상이 다각형으로 형성되므로 직선운동은 가능하지만 회전운동이 구속되게 케이스(52) 내부에 설치된다.Since the nut screw 70 is formed in a polygonal cross-sectional shape, linear motion is possible, but is installed inside the case 52 so that rotational motion is constrained.

이로써, 별도의 가이드나 연결부재 없이 너트스크루(70)가 케이스(52) 내부에 직선운동 가능하고 회전운동이 구속되게 설치된다.As a result, the nut screw 70 can be linearly moved inside the case 52 without any guide or connecting member, and the rotational movement is restrained.

너트스크루(70)의 일측에는 볼트스크루(60)가 나사결합 되고, 타측에는 주차케이블(80)이 연결되는 삽입홀부(72)가 구비되며, 삽입홀부(72)와 연통되는 체결홀부(74)가 구비된다.One side of the nut screw 70 is screwed to the bolt screw 60, the other side is provided with an insertion hole 72 is connected to the parking cable 80, the fastening hole portion 74 in communication with the insertion hole (72) Is provided.

또한, 주차케이블(80)에는 삽입홀부(72)에 끼워져 체결홀부(74)를 통해 삽입되는 체결부재(76)와 결하되는 고정부(82)가 구비된다.In addition, the parking cable 80 is provided with a fixing portion 82 that is inserted into the insertion hole 72 and is coupled with the fastening member 76 inserted through the fastening hole 74.

이로써, 고정부(82)를 삽입홀부(72)에 끼운 후에 체결홀부(74)를 통해 체결 부재(76)를 삽입하여 고정부(82)와 결합시키면 너트스크루(70)와 주차케이블(80)이 연결된다.Thus, after the fixing portion 82 is inserted into the insertion hole 72, the fastening member 76 is inserted through the fastening hole portion 74 to be coupled with the fixing portion 82 to the nut screw 70 and the parking cable 80. Is connected.

이때, 너트스크루(70)는 회전운동이 구속되므로 주차케이블(80)과 회전 가능하게 연결시키는 별도의 회전부재가 요구되지 않는다.At this time, since the nut screw 70 is constrained in the rotational movement, a separate rotating member for rotatably connecting the parking cable 80 is not required.

상기와 같이 구성된 본 발명의 일 실시예에 따른 차량의 주차 브레이크용 액추에이터의 작용을 살펴보면 다음과 같다.Looking at the operation of the actuator for the parking brake of the vehicle according to an embodiment of the present invention configured as described above are as follows.

먼저, 액추에이터(50)를 조립할 때는 너트스크루(70)의 삽입홀부(72)에 주차케이블(80)의 고정부(82)를 삽입하고, 체결홀부(74)를 통해 체결부재(76)를 삽입하여 고정부(82)와 결합하면 너트스크루(70)와 주차케이블(80)의 연결을 별도의 회전부재 없이 결합할 수 있게 된다.First, when assembling the actuator 50, the fixing portion 82 of the parking cable 80 is inserted into the insertion hole portion 72 of the nut screw 70, and the fastening member 76 is inserted through the fastening hole portion 74. When combined with the fixing portion 82 it is possible to combine the connection of the nut screw 70 and the parking cable 80 without a separate rotating member.

이렇게 결합되는 너트스크루(70)와 주차케이블(80)은 손쉽게 연결 또는 분리가 가능하므로 액추에이터(50)의 고장이 발생되어 수리작업을 행할 때에 용이한 분리 및 결합을 행할 수 있게 된다.Since the nut screw 70 and the parking cable 80 coupled as described above can be easily connected or separated, a breakdown of the actuator 50 occurs, so that the nut screw 70 and the parking cable 80 can be easily separated and combined when performing a repair work.

상기한 바와 같이 연결되는 너트스크루(70)와 주차케이블(80)을 케이스(50) 내부에 조립하여 볼트스크루(60)와 결합함으로써, 액추에이터(50)의 조립을 완성하게 된다.By assembling the nut screw 70 and the parking cable 80 connected as described above in the case 50 and combined with the bolt screw 60, the assembly of the actuator 50 is completed.

이렇게 조립된 액추에이터(50)는 모터(54)가 구동되면 회전하는 종동기어(62)에 의해 볼트스크루(60)가 회전되는데, 볼트스크루(60)는 직선운동이 구속되므로 볼트스크루(60)와 나사결합 되는 너트스크루(70)가 직선운동하게 된다.The assembled actuator 50 is rotated by the driven gear 62 is rotated when the motor 54 is driven, the bolt screw 60 is rotated, the bolt screw 60 is constrained linear movement bolt bolt 60 and The nut screw 70 to be screwed is linearly moved.

이렇게 너트스크루(70)가 직선운동 하면서 주차케이블(80)에 인장력을 가하 거나 인장력을 해제하게 되는데, 이는 모터(54)의 정회전 또는 역회전에 의해 이루어지게 된다.In this way, the nut screw 70 is applied to the parking cable 80 while applying a tensile force or to release the tensile force, which is made by the forward or reverse rotation of the motor (54).

본 발명은 도면에 도시된 실시예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다.Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand.

또한, 차량의 주차 브레이크용 액추에이터를 예로 들어 설명하였으나, 이는 예시적인 것에 불과하며, 차량의 주차 브레이크에 사용되는 액추에이터가 아닌 다른 제품에도 본 발명의 액추에이터가 사용될 수 있다.In addition, although an example of an actuator for a parking brake of a vehicle has been described as an example, this is merely an example, and the actuator of the present invention may be used for a product other than the actuator used for the parking brake of the vehicle.
