[산업상 이용 분야][Industrial use]

본원 고안은 클러치 마스터 실린더 내에서 유압발생을 위해 운동하는 클러치 피스톤의 누유 방지 구조에 관한 것이다.The present invention relates to a leakage preventing structure of a clutch piston that moves for generating hydraulic pressure in a clutch master cylinder.

[종래 기술][Prior art]

종래 클러치 마스터 실린더 내에 내장되어 슬라이딩 운동하는 클러치 피스톤(1)은 제3도에서와 같이 실린더 내면에 밀착하여 작동액의 누출을 일으키지 않도록 오일링(3, 패킹)을 구비하고 있다.The clutch piston 1, which is conventionally incorporated in the clutch master cylinder and slides, has an oil ring 3 (packing) so as to be in close contact with the inner surface of the cylinder as in FIG.

[종래 기술의 문제점][Problems with Prior Art]

그러나, 상기한 구조의 경우 오일링(3)의 마모시 유압저하로 마찰재가 소슨되는 문제점이 지적되고 있다.However, in the case of the above-described structure, it is pointed out that the friction material is sosoned due to the hydraulic pressure drop when the oil ring 3 is worn.

[고안이 해결하고자 하는 과제][Problem to Solve]

이에 본원은 상기한 문제점을 감안하여 안출한 것으로서 그의 목적으로 하는 바는 클러치 피스톤에 마련된 오일링의 마모를 보상하므로써 누유 방지 효과를 얻을 수 있는 클러치 피스톤의 누유 방지 구조를 제공하는 데 있다.Accordingly, the present application has been made in view of the above-described problems, and an object thereof is to provide a leakage preventing structure of a clutch piston that can obtain a leakage preventing effect by compensating for wear of an oil ring provided on a clutch piston.

[과제를 달성하기 위한 수단][Means for achieving the task]

상기한 목적을 달성하기 위한 본원 고안의 구성은 클러치 마스터 실린더 내면과의 사이에 누설을 방지하기 위해 마련되는 오일링을 갖는 클러치 피스톤에 있어서, 상기 오일링과 클러치 피스톤과의 사이에는 탄성성이 있는 웨이브링을 삽입시킨 것을 특징으로 한다.The configuration of the present invention for achieving the above object is a clutch piston having an oil ring provided to prevent leakage between the inner surface of the clutch master cylinder, the elastic ring between the oil ring and the clutch piston The wave ring is inserted.

[실시예]EXAMPLE

이하 본 고안의 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

제1도는 본 고안에 의한 클러치 피스톤의 단면도이며, 제2도는 웨이브링의 형상을 나타내는 도면이다.1 is a cross-sectional view of the clutch piston according to the present invention, Figure 2 is a view showing the shape of the wave ring.

도면 중 부호 1은 클러치 피스톤으로 클러치 피스톤(1)의 외주변에는 요홈(2)이 형성되고 있고 요홈(2) 내에는 오일링(3)과 웨이브링(4)에 수용된다.In the drawing, reference numeral 1 denotes a clutch piston, and a recess 2 is formed at an outer periphery of the clutch piston 1, and the recess 2 is accommodated in the oil ring 3 and the wave ring 4.

상기 오일링(3)은 클러치 마스터 실린더와의 사이에 작동액이 누설되는 것을 방지하는 역할을 하게 되는데 오래 사용하다보면 마모가 되어 누설을 일으킬 우려가 높아진다.The oil ring 3 serves to prevent the hydraulic fluid from leaking between the clutch master cylinder and the oil ring 3 wears out for a long time, thereby increasing the risk of leakage.

이 때 웨이브링(4)의 탄발력으로 오일링(3)의 마모량만큼은 보상하게 되며 이를 위해 웨이브링(4)은 제2도에서와 같이 탄성력이 있는 재질은 요철을 형성하도록 즉 파도형상으로 구부려서 형성하며 오일링(3)이 마모시에 눌려 있던 웨이브링(4)이 원래 형상을 회복하면서 마모 보상을 하게 되는 것이다.In this case, the elasticity of the wave ring 4 compensates for the amount of wear of the oil ring 3. For this purpose, the wave ring 4 is bent in a wave shape to form an uneven material as shown in FIG. 2. When the oil ring 3 is pressed, the wave ring 4, which is pressed at the time of wear, restores its original shape to compensate for wear.

[효과][effect]

이상과 같은 본원 고안에 의하면 클러치 피스톤의 오일링에 탄성력을 가하는 웨이브링을 구비하고 있어 오일링이 마모되더라도 클러치 마스터 실린더와의 틈새를 통해 오일이 누설되는 것을 방지하게 된다.According to the present invention as described above is provided with a wave ring for applying an elastic force to the oil ring of the clutch piston to prevent the oil leakage through the gap with the clutch master cylinder even if the oil ring is worn.
