본 발명은 수동변속기의 마스터실린더와 릴리스실린더를 연결하는 유압라인 의 구조를 변경하여 클러치패달 리턴성능을 향상시키는 것과 관련된다.The present invention relates to improving the clutch pedal return performance by changing the structure of the hydraulic line connecting the master cylinder and the release cylinder of the manual transmission.

수동변속기에는 기어변속 및 자동차의 동력차단을 위한 클러치가 사용되는데, 클러치의 작동을 위해 클러치패달을 밟게 되면 패달에 연결된 클러치 마스터실린더(이하, "마스터실린더"라 함)가 유압을 형성하여 유로를 통해 클러치 릴리스실린더(이하, "릴리스실린더"라 함)를 작동시켜 변속기 내부의 클러치를 단속하도록 구성되어 있다.In the manual transmission, a clutch for gear shifting and power cut-off of the vehicle is used.When the clutch pedal is pressed to operate the clutch, the clutch master cylinder (hereinafter referred to as the "master cylinder") connected to the pedal generates hydraulic pressure to By operating the clutch release cylinder (hereinafter referred to as "release cylinder") is configured to interlock the clutch inside the transmission.

도1을 참조하여 마스터실린더(2)와 릴리스실린더(3)를 연결하는 유압라인(10)의 구조를 살펴보면, 통상적으로 유압라인(10)에는 유압댐퍼(20)와 코일스프링 형태로 유압라인(10)의 길이를 길게 연장시킨 유로연장부(11)가 마련되어 있다. 이러한 유압댐퍼(20)와 유로연장부(11)는, 엔진폭발 시 발생하는 진동이 유압맥동을 형성하여 진동필터링이 이루어지지 않은 채 클러치패달(1) 측으로 전달되는 것을 방지하기 위한 구성에 해당한다.Referring to the structure of the hydraulic line 10 connecting the master cylinder (2) and the release cylinder (3) with reference to Figure 1, typically, the hydraulic line (10) in the hydraulic damper 20 and coil spring form hydraulic line ( The flow path extension part 11 which extended the length of 10) is provided. The hydraulic damper 20 and the passage extension portion 11 correspond to a configuration for preventing the vibration generated during the engine explosion from forming the hydraulic pulsation to be transmitted to the clutch pedal 1 without vibrating filtering. .

그러나, 유압라인(10)의 길이가 길게 하거나 유압라인(10)에 유압댐퍼(20)를 장착하는 경우, 유압진동은 개선될 수 있으나 유압에 의한 응답성능이 저하되어 클러치패달(1) 리턴시 페달(1)이 천천히 올라오는 문제가 발생한다.However, when the length of the hydraulic line 10 is long or when the hydraulic damper 20 is mounted on the hydraulic line 10, the hydraulic vibration can be improved, but the response performance due to the hydraulic pressure decreases and the clutch pedal 1 returns. The pedal 1 rises slowly.

본 발명은 이러한 문제점을 해결하기 위하여 제안된 것으로, 유압진동의 저감이 가능하며 유압의 리턴이 원활해져 클러치패달의 리턴속도가 향상되도록 한 수변속기의 클러치패달의 리턴성능 개선구조를 제공함을 목적으로 한다.The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a structure for improving the return performance of the clutch pedal of a water transmission in which the hydraulic vibration can be reduced and the return of the hydraulic pressure is improved by improving the return of the hydraulic pressure. .

상기의 목적을 달성하기 위한 본 발명에 따른 수동변속기의 클러치패달 리턴성능 개선구조를 갖는 클러치 장치는, 수동변속기의 마스터실린더와 릴리스실린더를 연결하는 유압라인의 일부 구간 또는 전체가 병렬배치된 제1유압라인과 제2유압라인으로 구성되되, 제1유압라인은 마스터실린더로부터 릴리스실린더로만 유압이 공급될 수 있도록 하기 위한 제1 일방향밸브가 설치되며, 제2유압라인은, 릴리스실린더로부터 마스터실린더로만 유압이 공급될 수 있도록 하기 위한 제2 일방향밸브가 설치된 것을 특징으로 한다.Clutch device having a clutch pedal return performance improvement structure of the manual transmission according to the present invention for achieving the above object, the first portion of the hydraulic line connecting the master cylinder and the release cylinder of the manual transmission is arranged in parallel first Comprising a hydraulic line and a second hydraulic line, the first hydraulic line is provided with a first one-way valve for supplying hydraulic pressure only from the master cylinder to the release cylinder, the second hydraulic line is from the release cylinder to the master cylinder only It characterized in that the second one-way valve for installing the hydraulic pressure is provided.

이때, 제2유압라인은 제1유압라인 보다 유로직경이 클 수 있다.At this time, the second hydraulic line may have a larger flow path diameter than the first hydraulic line.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 따른 수동변속기의 클러치패달 리턴성능 개선구조를 갖는 클러치 장치에 대하여 살펴본다.Hereinafter, a clutch device having a clutch pedal return performance improving structure of a manual transmission according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

본 발명에 따른 유압라인은 구간 일부 또는 전체가 병렬배치된 2개의 유압라인으로 구성될 수 있다. 이는 클러치패달을 밟을 때와 클러치패달을 복원시킬 때에 따른 서로 구별되는 유압라인을 따라 유압이 공급될 수 있도록 하기 위함이다.The hydraulic line according to the present invention may be composed of two hydraulic lines in which part or all of the sections are arranged in parallel. This is to allow the hydraulic pressure to be supplied along the hydraulic lines which are distinguished from each other when the clutch pedal is pressed and when the clutch pedal is restored.

일례로서, 도2에 도시된 바와 같이 유압라인(30)은, 병렬배치된 2개의 유압라인(30a, 30b)으로 분기된 다음, 다시 하나의 라인(30)으로 합쳐질 수 있다. 물론, 유압라인(30) 전체, 즉 유압라인(30) 자체가 2개의 유압라인으로 구성될 수 있다. 그러나, 이러한 경우에는 2개의 유압라인을 연결할 수 있도록 마스터실린더(2)와 릴리스실린더(3)의 유압라인 연결부 구조를 변경해야 하므로, 도2에 도시된 바와 같은 유압라인의 구조가 보다 바람직하다.As an example, as shown in FIG. 2, the hydraulic lines 30 may be branched into two hydraulic lines 30a and 30b arranged in parallel, and then merged into one line 30 again. Of course, the entire hydraulic line 30, that is, the hydraulic line 30 itself may be composed of two hydraulic lines. However, in this case, since the structure of the hydraulic line connecting portion of the master cylinder 2 and the release cylinder 3 must be changed to connect two hydraulic lines, the structure of the hydraulic line as shown in FIG. 2 is more preferable.

제1유압라인(10a)에는, 마스터실린더(2)로부터 릴리스실린더(3)로만 유압이 공급되도록 하기 위한 제1 일방향밸브(30a)가 설치되며, 또한, 종래의 유압댐퍼(20)와 유로연장부(11)가 마련된다. 클러치패달(1)이 가압하는 경우 유압은 제1유압라인(10a)을 따라 변속기로 전달되며, 이때 유압진동은 유압댐퍼(20)와 유로연장부(11)에 의해 저감된다.The first hydraulic line 10a is provided with a first one-way valve 30a for supplying hydraulic pressure only from the master cylinder 2 to the release cylinder 3, and also extends a conventional hydraulic damper 20 and a flow path. Part 11 is provided. When the clutch pedal 1 is pressurized, the hydraulic pressure is transmitted to the transmission along the first hydraulic line 10a, wherein the hydraulic vibration is reduced by the hydraulic damper 20 and the passage extension portion 11.

제1 일방향밸브(30a)는 유압댐퍼(20)나 유로연장부(11) 보다 릴리스실린더(3) 측에 가까운 위치에 배치하는 것이 좋다. 즉, 릴리스실린더(3) 측에서 유압라인(10)이 분기되는 지점부근에 제1 일방향밸브(30a)가 설치된다. 이는 릴리스실린더(3) 측으로부터 전달되는 유압이 되도록 제2유압라인(10b)으로만 전달되도록 하여 클러치페달(1)의 리턴성능이 저하되지 않도록 하기 위함이다.The first one-way valve 30a may be disposed at a position closer to the release cylinder 3 side than the hydraulic damper 20 or the passage extension portion 11. That is, the first one-way valve 30a is installed near the point where the hydraulic line 10 branches on the release cylinder 3 side. This is to ensure that the return performance of the clutch pedal 1 is not deteriorated by being transmitted only to the second hydraulic line 10b so that the hydraulic pressure transmitted from the release cylinder 3 side.

클러치패달(1)을 리턴시키기 위한 유압은 제2유압라인(10b)을 통하여 전달된다. 다만, 제2유압라인(10b)에도 일방향밸브(30b)가 설치되어 있어, 제2유압라인(10b)의 경우 유압은 릴리스실린더(3)로부터 마스터실린더(2)측으로만 전달될 수 있다.The hydraulic pressure for returning the clutch pedal 1 is transmitted through the second hydraulic line 10b. However, since the one-way valve 30b is also installed in the second hydraulic line 10b, in the case of the second hydraulic line 10b, the hydraulic pressure may be transmitted only from the release cylinder 3 to the master cylinder 2 side.

이러한 제2유압라인(10b)은 클러치패달(1)의 리턴을 위한 유압을 제공하기 위한 유압라인으므로, 제1유압라인(10a)과는 달리 유로연장부(11)나 유압댐퍼(20)가 마련될 필요가 없다. 오히려, 제2유압라인(10b)은 클러치패달(1)의 리턴성능의 향상을 위해 제1유압라인(10a) 보다 길이가 짧아야 하며, 유로직경은 더 클 필요가 있다.Since the second hydraulic line 10b is a hydraulic line for providing hydraulic pressure for the return of the clutch pedal 1, unlike the first hydraulic line 10a, the flow path extension part 11 or the hydraulic damper 20 is provided. There is no need to be prepared. Rather, the second hydraulic line 10b should be shorter than the first hydraulic line 10a in order to improve the return performance of the clutch pedal 1, and the flow path diameter needs to be larger.

도2 및 도3을 참조하여, 일방향밸브의 구조를 살펴본다.Referring to Figures 2 and 3, looks at the structure of the one-way valve.

먼저 제1유압라인(10a)에 설치된 제1 일방향밸브(30a)에 대하여 살펴보면, 일방향밸브(30a)는, 유공(31a)을 갖는 밸브오리피스(31)를 스프링(33)의 탄성력을 매개로 폐쇄하고 있는 스틸볼(32)로 구성된다. 스프링(33)의 후방은 유공(34a)를 갖는 스토퍼(34)에 의해 지지된다. 따라서, 밸브오리피스(31) 측으로부터 스피링(33)을 가압하는 방향으로 압력이 가해지는 경우, 유압이 전달될 수 있으나 그 반대의 경우에는 유압이 전달되지 않는다.First, the first one-way valve 30a installed in the first hydraulic line 10a will be described. The one-way valve 30a closes the valve orifice 31 having the oil hole 31a through the elastic force of the spring 33. It consists of the steel balls 32 which are being made. The rear of the spring 33 is supported by a stopper 34 having a hole 34a. Therefore, when pressure is applied in the direction of pressing the spring 33 from the valve orifice 31 side, the hydraulic pressure may be transmitted, but vice versa.

제2유압라인(10b)에 설치된 제1 일방향밸브(30b)는 제1 일방향밸브(30a)와 놓여진 위치만 다를 뿐 제1 일방향밸브와 동일한 구조로 이루어져 있다.The first one-way valve 30b installed in the second hydraulic line 10b has the same structure as that of the first one-way valve, except that the first one-way valve 30b is different from the position of the first one-way valve 30a.

상술한 바와 같은 구조로 이루어진 수동변속기의 클러치패달 리턴성능 개선구조를 갖는 클러치 장치에 따르면, 클러치패달을 밟을 때에는 제1유압라인을 통하여 유압이 전달되므로 클러치패달로 전달되는 유압진동이 방지되며, 클러치패달 리턴 시에는 제2유압라인을 통하여 유압이 원활히 전달되므로 클러치패달의 리턴성능이 향상된다.According to the clutch device having a clutch pedal return performance improvement structure of a manual transmission having the structure as described above, when the clutch pedal is pressed, the hydraulic pressure is transmitted through the first hydraulic line, thereby preventing the hydraulic vibration transmitted to the clutch pedal. When the pedal returns, the hydraulic pressure is smoothly transmitted through the second hydraulic line, thereby improving the return performance of the clutch pedal.
