그러나, 유압이 작용될 때 변속타임을 0(Zero)으로 하면서 그 충격을 적도록 여유간극이 0인 것이 요구되어 자유상태와 유압 작동 상태에서의 요구조건이 다른 문제점을 가지고 있다. However, when the hydraulic pressure is applied, the shift time is set to zero and the clearance gap is required to reduce the shock, so that the requirements in the free state and the hydraulic operation state have different problems.                         

이러한 여유간극을 유압으로 가압해서 피스톤이 움직이는 시간은 필타임(Fill Time)이라 하고 제어 팩터로 관리한다.The time that the piston moves by hydraulically pressurizing this clearance is called fill time and is controlled by the control factor.

본 발명의 목적은 초기 가압시 리턴 스프링의 힘과 여유간극 접근후의 리턴 스프링의 힘을 2원화해서 필 타임 시간 및 저항을 최소화할 수 있으며, 디스크 가압시 전체 스프링 힘이 작동 할 수 있어 해제시 빠른 리턴이 가능하게 할 수 있는 자동 변속기의 클러치 세트를 제공하는데 있다.It is an object of the present invention to minimize the fill time time and resistance by dualizing the return spring force at initial pressurization and the return spring force after clearance clearance, and the entire spring force at disk pressurization can be operated to release the fast It is to provide a clutch set of an automatic transmission that can enable a return.

상기와 같은 목적을 달성하기 위하여 본 발명은 자동 변속기의 클러치 세트에 있어서, 여유간극 접근 후 가압부인 급경사부와; 상기 급경사부와 인접되도록 형성되어 초기 가압부 기능을 하는 완경사부를 갖도록 스프링의 끝단부가 2원화된 리턴 스프링을 포함하여 구성하는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a clutch set of an automatic transmission comprising: a steep inclination portion that is a pressing portion after approaching a clearance gap; It is formed to be adjacent to the steep inclination portion is characterized in that it comprises a return spring is a two-way end of the spring so as to have a mild inclined portion to function as the initial pressing portion.

이하 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 상세히 설명한다. 하기 설명 및 첨부 도면과 같은 많은 특정 상세들이 본 발명의 보다 전반적인 이해를 제공하기 위해 나타나 있으나, 이들 특정 상세들은 본 발명의 설명을 위해 예시한 것으로 본 발명이 그들에 한정됨을 의미하는 것은 아니다. 그리고 본 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능 및 구성에 대한 상세한 설명은 생략한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. While many specific details, such as the following description and the annexed drawings, are shown to provide a more general understanding of the invention, these specific details are illustrated for the purpose of explanation of the invention and are not meant to limit the invention thereto. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

FIG. 3 is a side view of the return spring 310 according to the embodiment of the present invention. 4 is a front view of a return spring 310 according to an embodiment of the present invention.

도 3과 도 4를 참조하여 본 발명의 실시예에 따른 자동 변속기의 클러치 세트를 구성하는 리턴 스프링(310)의 형상 및 기능을 설명한다.3 and 4 will be described the shape and function of the return spring 310 constituting the clutch set of the automatic transmission according to the embodiment of the present invention.

본 발명의 실시예는 자동 변속기의 클러치 세트를 구성하는 리턴 스프링(310)에 관한 것이며, 리턴 스프링(310)은 도 3과 도 4에 도시된 바와 같이 급경사부(312)와 완경사부(314)를 갖는다.An embodiment of the present invention relates to a return spring 310 constituting a clutch set of an automatic transmission, the return spring 310 is a steep portion 312 and a mild slope portion 314 as shown in Figs. Has

급경사부(312)는 여유간극 접근 후 가압부이며, 완경사부(314)는 급경사부(312)와 인접되도록 형성되어 초기 가압부 기능을 한다.The steep slope 312 is a pressing portion after the clearance gap approach, the gentle slope 314 is formed to be adjacent to the steep slope 312 to function as the initial pressing portion.
