Referring to FIG. 4, as the driver operates the lever in the D-stage, the hydraulic device 1 for the multi-stage transmission performs the steps of D, (51, 52, 53, 54, 55, 56).

즉, 공급부(10)를 통해 공급된 유압은 제1유압부(31)로 이동되고, 제1솔레노이드밸브부(41)에 의해 제1클러치부(51)로 작동압이 도달된다.That is, the hydraulic pressure supplied through the supply portion 10 is moved to the first hydraulic pressure portion 31, and the operating pressure reaches the first clutch portion 51 by the first solenoid valve portion 41.

그리고, 매뉴얼밸브부(60)가 D단압부(80)로의 유압 흐름을 인가함에 따라, 매뉴얼밸브부(60)를 통과한 유압은 D단압부(80)를 거쳐 제3,제4,제5,제6유압부(33,34,35,36)로 각각 이동되고, 제3,제4,제5,제6솔레노이드밸브부(43,44,45,46)에 의해 제3,제4,제5,제6클러치부(53,54,55,56)로 작동압이 도달된다.As the manual valve unit 60 applies the hydraulic pressure to the D step pressure unit 80, the hydraulic pressure that has passed through the manual valve unit 60 flows through the D step pressure unit 80 to the third, Fourth, fifth, and sixth solenoid valve portions 43, 44, 45, and 46, respectively, and the third, fourth, fifth, and sixth hydraulic pressure portions 33, The operating pressure is reached by the fifth and sixth clutch portions 53, 54, 55,

이때, 매뉴얼밸브부(60)는 R단압부(70)로의 유압 흐름을 차단하고, 셔틀밸브부(90)는 D단압부(70)에서 제공되는 유압에 의해 D단압부(80)와 제2유압부(32)를 연결시켜 준다. 이로 인해, 매뉴얼밸브부(60)를 통과한 유압 중 일부는 D단압부(80)를 거쳐 제2유압부(32)로 이동되고, 제2솔레노이드밸브부(42)에 의해 제2클러치부(52)로 작동압이 도달된다.At this time, the manual valve unit 60 blocks the flow of the hydraulic pressure to the R step pressure unit 70 and the shuttle valve unit 90 is operated by the hydraulic pressure provided by the D step pressure unit 70, And the hydraulic pressure unit 32 is connected. A part of the hydraulic pressure that has passed through the manual valve unit 60 is moved to the second hydraulic pressure unit 32 via the D step pressure unit 80 and the second solenoid valve unit 42 moves the second clutch unit 52).

본 발명의 일 실시예에 따른 다단변속기용 유압장치(1)는 N단에서 매뉴얼밸브부(60)가 유압을 차단하므로, N단 비정상 주행을 예방할 수 있다.In the hydraulic device 1 for a multi-stage transmission according to the embodiment of the present invention, since the manual valve unit 60 blocks the hydraulic pressure in the N-th stage, the N-stage abnormal driving can be prevented.

본 발명의 일 실시예에 따른 다단변속기용 유압장치(1)는 비정상 주행 대처를 위한 페일세이프밸브가 삭제되므로, 제조비용을 절감될 수 있다.In the hydraulic device 1 for the multi-speed transmission according to the embodiment of the present invention, since the fail-safe valve for coping with the abnormal driving is eliminated, the manufacturing cost can be reduced.

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. 따라서, 본 발명의 진정한 기술적 보호범위는 아래의 특허청구범위에 의해서 정하여져야 할 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
