자동차용 클러치{Clutch for automobile}Clutch for automobile

본 발명은 자동차용 클러치에 관한 것으로, 특히 클러치의 디스크와 압력판어셈블리 간에 발생하는 열을 효과적으로 방출할 수 있도록 된 자동차용 클러치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile clutch, and more particularly, to an automobile clutch that is capable of effectively dissipating heat generated between a disc and a pressure plate assembly of a clutch.

일반적으로, 자동차의 클러치는 플라이휠과 변속기 사이에 설치되어 변속기에 전달되는 엔진의 동력을 필요에 따라 단속하는 일을 하는 장치로, 엔진을 시동할 때 또는 기어변속을 할 때에는 엔진과의 연결을 차단하고 출발할 때에는 엔진의 동력을 서서히 연결하는 역할을 하는 동력전달장치의 구성요소이다.In general, the clutch of a vehicle is a device that is installed between the flywheel and the transmission to control the power of the engine transmitted to the transmission as necessary, and disconnects the engine when starting the engine or shifting gears. When starting, it is a component of the power train that serves to connect the power of the engine slowly.

도 1은 상기와 같은 일반적인 클러치의 일례를 나타낸 것으로, 클러치는 도 1에 도시된 바와 같이, 플라이휠(2)과 단속적으로 마찰 접촉하며 플라이휠(2)의 회동력을 전달받아 변속기(미도시)의 동력축(1)에 전달하게 되는 디스크(3)와, 이 디스크(3)를 가압하여 플라이휠에 압착시켜주는 클러치 커버의 압력판어셈블리(4)와, 페달(미도시)의 작동에 의해 상기 압력판어셈블리(4)를 동작시키는 다이어프램스프링(5)으로 구성된다.Figure 1 shows an example of such a general clutch, as shown in Figure 1, the clutch is intermittently frictional contact with the flywheel (2) receives the rotational force of the flywheel (2) of the transmission (not shown) The disk 3 to be transmitted to the power shaft 1, the pressure plate assembly 4 of the clutch cover which presses the disk 3 and compresses the flywheel, and the pressure plate assembly by the operation of a pedal (not shown). It consists of the diaphragm spring 5 which operates (4).

따라서, 운전자가 클러치 페달을 누르게 되면, 상기 다이어프램스프링(5)의 작동에 의해 압력판어셈블리(4)가 디스크(3)로부터 분리되면서 디스크(3)와 플라이휠(2) 간의 압착이 해제되고, 이로써 플라이휠(2)의 동력전달은 중단된다.Therefore, when the driver presses the clutch pedal, the pressure plate assembly 4 is separated from the disk 3 by the operation of the diaphragm spring 5, thereby releasing the compression between the disk 3 and the flywheel 2, thereby releasing the flywheel. Power transmission in (2) is stopped.

그런데, 상기와 같은 종래의 클러치에서는 클러치 커버의 압력판어셈블리(4)가 회전중인 디스크(3)를 가압할 때 압력판어셈블리(4)와 디스크(3)의 접촉면에 강한 마찰열이 발생하게 되고, 이러한 마찰열은 각 구성부에 열에 의한 손상을 초래하고 수명을 단축시키게 되는 문제점을 유발하였다.However, in the conventional clutch as described above, when the pressure plate assembly 4 of the clutch cover presses the rotating disk 3, strong frictional heat is generated on the contact surface between the pressure plate assembly 4 and the disk 3, and such friction heat This causes a problem that causes heat damage to each component and shortens the life.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 클러치의 구조를 개선하여 클러치의 디스크와 압력판어셈블리 간에 발생하는 마찰열을 효과적으로 외부로 방출할 수 있도록 한 자동차용 클러치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to provide a clutch for an automobile that can effectively release the frictional heat generated between the disk and the pressure plate assembly of the clutch by improving the structure of the clutch. have.

상기와 같은 목적을 달성하기 위하여 본 발명은, 플라이휠과 단속적으로 마찰 접촉하며 플라이휠의 회동력을 변속기의 동력축에 전달하는 디스크와, 이 디스크를 가압하여 플라이휠에 압착시켜주는 클러치 커버의 압력판어셈블리와, 페달의 작동에 의해 상기 압력판어셈블리를 동작시키는 작동스프링으로 구성된 클러치에 있어서, 상기 디스크의 동력축과 결합되는 허브에는 디스크의 회전시 공기를 송풍시키도록 다수의 블레이드(blade)가 소정간격을 두고 방사상으로 돌출되게 형성되고, 상기 압력판어셈블리에는 상기 블레이드에 의해 생성된 송풍 공기가 외부로 통풍되도록 다수의 통기공이 방사상으로 형성된 것을 특징으로 하는 자동차용 클러치를 제공한다.In order to achieve the above object, the present invention, the disk intermittently frictional contact with the flywheel and transmits the rotational force of the flywheel to the power shaft of the transmission, and the pressure plate assembly of the clutch cover for pressing the disk to press the flywheel In the clutch consisting of a working spring for operating the pressure plate assembly by the operation of the pedal, the hub coupled to the power shaft of the disk a plurality of blades (blade) at a predetermined interval to blow air when the disk is rotated It is formed to protrude radially, the pressure plate assembly provides a vehicle clutch, characterized in that a plurality of vents are radially formed so that the blowing air generated by the blade is vented to the outside.

본 발명의 한 형태에 따르면, 상기 블레이드는 디스크 허브의 원주방향을 따라 120°간격으로 이격되어 형성된 것을 특징으로 한다.According to one aspect of the invention, the blades are characterized by being spaced apart at intervals of 120 ° along the circumferential direction of the disk hub.

이하, 본 발명에 따른 자동차용 클러치의 일 실시예에 대해 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, an embodiment of a clutch for an automobile according to the present invention will be described in detail with reference to the accompanying drawings.

도 2 내지 도 6은 본 발명에 따른 자동차용 클러치의 일 실시예의 구조와 작동 상태를 나타낸 것으로, 도 2 내지 도 6에 도시된 바와 같이, 본 발명의 클러치는 플라이휠(2)과 단속적으로 마찰 접촉하며 플라이휠(2)의 회동력을 전달받아 변속기(미도시)의 동력축(1)에 전달하게 되는 디스크(30)와, 이 디스크(30)를 가압하여 플라이휠(2)에 압착시켜주는 클러치 커버의 압력판어셈블리(40)와, 페달(미도시)의 작동에 의해 상기 압력판어셈블리(40)를 동작시키는 다이어프램스프링(5)으로 구성된다.2 to 6 show the structure and operating state of an embodiment of a clutch for an automobile according to the present invention, as shown in FIGS. 2 to 6, the clutch of the present invention is intermittently frictional contact with the flywheel 2. And a disc 30 which receives the rotational force of the flywheel 2 and transmits it to the power shaft 1 of the transmission (not shown), and a clutch cover that presses the disc 30 to press the flywheel 2. Pressure plate assembly 40, and a diaphragm spring 5 for operating the pressure plate assembly 40 by the operation of a pedal (not shown).

여기서, 상기 디스크(30)의 내측부를 이루는 디스크 허브(301)에는 상기 압력판어셈블리(40) 쪽을 향한 면에 방사상으로 돌출되게 형성된 다수의 블레이드(302; blade)들이 소정 간격으로 형성되어, 디스크(30)의 회전시 반경방향 외측으로 공기를 송풍시키게 되는데, 본 실시예에서는 상기 블레이드(302)들은 디스크 허브(301)의 원주방향으로 120°간격을 이격되어 형성되어 있다.Here, the disk hub 301 forming the inner portion of the disk 30 has a plurality of blades (302) formed to protrude radially on the surface toward the pressure plate assembly 40 is formed at predetermined intervals, the disk ( The air is blown outward in the radial direction during the rotation of 30. In this embodiment, the blades 302 are formed to be spaced apart by 120 ° in the circumferential direction of the disk hub 301.

그리고, 상기 클러치 커버의 외측부를 이루는 압력판어셈블리(40)에는 상기 디스크 허브(301)의 블레이드(302)에서 생성된 송풍 공기를 압력판어셈블리(40) 외부로 통풍시키기 위한 다수의 통기공(402)이 방사상으로 형성되어 있다.In addition, the pressure plate assembly 40 forming the outer portion of the clutch cover has a plurality of vent holes 402 for ventilating the blown air generated by the blade 302 of the disc hub 301 to the outside of the pressure plate assembly 40. It is formed radially.

따라서, 운전도중 운전자가 기어변속 조작을 위해 클러치 페달을 밟으면 다이어프램스프링(5)의 작동에 의해 디스크(30)로부터 압력판어셈블리(40)가 분리되면서 플라이휠(2)의 동력 전달이 중단되고, 기어변속 조작후 다시 페달을 놓으면 다이어프램스프링(5)의 작동에 의해 압력판어셈블리(40)가 회전중인 디스크(30)를 강하게 가압하게 되고, 이에 따라 디스크(30)가 플라이휠(2)에 압착되면서 다시 동력을 전달받게 된다.Therefore, when the driver presses the clutch pedal for the gear shifting operation, the pressure plate assembly 40 is separated from the disk 30 by the operation of the diaphragm spring 5, and the power transmission of the flywheel 2 is stopped. When the pedal is released after the operation, the pressure plate assembly 40 strongly presses the rotating disk 30 by the operation of the diaphragm spring 5, and thus, the disk 30 is pressed against the flywheel 2 to apply power again. You will be delivered.

이 때, 상기 회전중인 디스크(30)와 압력판어셈블리(40)의 접촉면에는 강한마찰력이 발생하게 되는 바, 도 6에 도시된 바와 같이, 상기 디스크(30)가 회전함에 따라 디스크 허브(301)에 형성된 블레이드(302)에 의해 반경방향 외측으로 공기가 송풍되게 되고, 이렇게 생성된 송풍 공기는 압력판어셈블리(40)의 통기공(402)을 통해 외부로 배출되면서 디스크(30)와 압력판어셈블리(40)의 마찰에 의해 발생된 열을 클러치 외부로 방출시키게 된다.At this time, a strong frictional force is generated on the contact surface of the rotating disk 30 and the pressure plate assembly 40, as shown in Figure 6, as the disk 30 rotates to the disk hub 301 Air is blown out radially outward by the blade 302 formed, and the blown air is thus discharged to the outside through the vent hole 402 of the pressure plate assembly 40, the disk 30 and the pressure plate assembly 40 Heat generated by the friction of the will be released to the outside of the clutch.

이상에서와 같이 본 발명에 따르면, 디스크의 회전시 블레이드에 의해 공기가 송풍되고, 이 송풍된 공기가 압력판어셈블리의 통기공을 통과하면서 디스크 표면과 압력판어셈블리 간에 생성된 마찰열이 효과적으로 방출되므로 열에 의한 디스크와 압력판어셈블리의 손상을 방지함과 더불어 수명을 연장시킬 수 있게 된다.As described above, according to the present invention, the air is blown by the blades when the disk rotates, the frictional heat generated between the disk surface and the pressure plate assembly is effectively released while the blown air passes through the vent hole of the pressure plate assembly, the disk by heat And prevent damage to the pressure plate assembly and extend its life.
