Description

농기계 및 자동차 케이블 타입의 클러치폐달의 답력경감장치{Device for reducing pedaling-power of clutch}Device for reducing pedaling-power of clutch

본 발명은 트랙터나 경운기등과 같은 농기계 및 자동차 케이블 타입의 클러치폐달 답력경감장치에 관한 것으로서, 특히 농기계의 클러치폐달 답력을 경감시켜 농기계를 조작하는 운전자들이 보다 쉽고 편리하게 농기계를 운전조작할 수 있도록 한 것이다.The present invention relates to a clutch pedal effort reducing device of agricultural machinery and automobile cable type, such as a tractor or a cultivator, in particular to reduce the clutch pedal pedal effort of the agricultural machinery to enable the driver to operate the farm machinery more easily and conveniently It is.

일반적으로 사용되고 있는 트랙터나 경운기와 같은 농기계의 클러치장치는 다음과 같이 구성되어 있다.Commonly used clutch devices for agricultural machinery such as tractors and tillers are configured as follows.

즉 운전자가 클러치폐달을 밟으면 클러치 폐달과 연결된 로드 및 케이블을 통하여 릴리즈포크를 작동시키게 되고, 따라서 동력을 전달 혹은 차단하게 되는 구성이다.That is, when the driver presses the clutch pedal, the release fork is operated through the rod and the cable connected to the clutch pedal, and thus the power is transmitted or cut off.

따라서 상기한 구성의 클러치폐달의 조작은 운전자가 약 15∼27Kg정도의 높은 답력으로 밟아야 하기 때문에 클러치조작에 많은 어려움이 따르게 되는 등의 문제점이 있는 것이었다.Therefore, the operation of the clutch pedal of the above-described configuration has a problem in that a lot of difficulties are involved in the clutch operation because the driver must step on a high effort of about 15 to 27 Kg.

본 발명은 이러한 종래의 제반 문제점을 시정하고자 운전자가 농기계를 운전 조작할 때 작은 답력으로 클러치폐달을 조작하더라도 동력의 전달, 혹은 차단이 가능케 구성하여 농기계의 운전이 용이하게 이루어질 수 있도록 한 것이다The present invention is intended to facilitate the operation of agricultural machinery by configuring the transmission or interruption of power even if the driver manipulates the clutch pedal with a small effort when operating the agricultural machinery to correct these problems.

상기 목적을 달성하기 위하여 본 발명은 별도로 장치한 진공배력장치를 클러치폐달과 연결하여 사용토록 하므로서 운전자 클러치페달을 밟으면 케이블과 연결된 진공배력장치의 피스톤이 당겨지게 되면서 대기의 공기가 진공배력장치내로 유입되어 피스톤에 의해 실린더내의 일측이 진공상태를 유지하는 실린더내로 유입되어 피스톤을 일측방향으로 밀게되고, 이와 연결된 푸쉬로드가 클러치폐달의 일측을 밀게하므로서 클러치폐달은 운전자가 발로 발판을 밟는 힘과 함께 진공배력장치의 푸쉬로드가 미는 힘이 동시에 작용하여 클러치폐달을 동작시키게 하여 작은힘으로서 클러치를 작동시키는 힘을 경감시킬 수 있도록 한 것이다.In order to achieve the above object, the present invention is to use the vacuum power unit separately installed in connection with the clutch pedal, stepping on the driver's clutch pedal while the piston of the vacuum power unit connected to the cable is pulled, atmospheric air flows into the vacuum power unit One side in the cylinder is introduced into the cylinder by the piston to push the piston in one direction, and the push rod connected thereto pushes one side of the clutch pedal, so the clutch pedal is vacuumed together with the driver's foot on the foot. The push rod push force of the booster acts at the same time to operate the clutch pedal to reduce the force to operate the clutch as a small force.

상기와 같이 구성된 진공배력장치는 농기계에만 적용하여 사용할 수 있는 것이 아니라, 유압 시스템을 사용하지 않는 수동 변속기 차량의 클러치콘트롤 시스템에 적용하여 사용할 수 있으며 그 작용효과는 동일하다.The vacuum powering device configured as described above can be used not only for agricultural machinery, but also for the clutch control system of a manual transmission vehicle that does not use a hydraulic system, and its effect is the same.

상부 일측에는 케이블(48)을 연결하여 클러치폐달(22)의 상단부(24)와 연결되게 하므로서 클러치폐달(22)을 밟으면 케이블(48)이 당겨지게 되고, 따라서 피스톤(10)이 이동되게 구성되어 있다.The upper one side is connected to the upper end 24 of the clutch pedal 22 by connecting the cable 48, the step of pressing the clutch pedal 22, the cable 48 is pulled, and thus the piston 10 is configured to move have.

또한 본체(4)일측에는 연결관체(50)를 구성하되, 상기 연결관체(50)에는 연결관(52)을 통하여 흡기매니홀드 및 진공펌프와 연결되게 구성하여서 된 것이다.In addition, one side of the main body 4 is configured to connect the connector 50, the connector 50 is configured to be connected to the intake manifold and the vacuum pump through the connection pipe (52).

미 설명부호 (60)은 에어필터, (62)는 부트, (64)는 체크밸브, (66)은 릴리즈포크, (68)은 축핀이다.Reference numeral 60 is an air filter, 62 is a boot, 64 is a check valve, 66 is a release fork, and 68 is an axial pin.

이와 같이 구성된 본 발명은 농기계에 장치된 클러치폐달(22)을 밟으면 축(26)을 중심으로 상단부(24)가 시계방향으로 회전하게 되면서, 이와 연결된 케이블(48)을 당기게 되고, 케이블(48)의 당김 작동에 의해 실린더부(8)내에 끼워진 피스톤(30)이 같은 방향으로 당겨지게 된다.According to the present invention configured as described above, when the clutch pedal 22 mounted on the agricultural machine is rotated clockwise around the shaft 26, the cable 48 connected thereto is pulled and the cable 48 is connected. The piston 30 fitted in the cylinder portion 8 is pulled in the same direction by the pulling operation of.

상기에서와 같이 피스톤(30)이 일측으로 이동하게 되면 포핏밸브(28)에 의해 실린더(4)내의 진공A실(34)과 연결된 출입공(36)이 차단됨과 동시에 브라켓(46)이 구성된 흡기공(44)을 통하여 유입된 대기의 공기는 관통공(38)및 연결관(40)을 통하여 진공실(42)로 유입된다.As described above, when the piston 30 moves to one side, the inlet hole 36 connected to the vacuum chamber A 34 in the cylinder 4 is blocked by the poppet valve 28 and the intake air in which the bracket 46 is formed. Air of the atmosphere introduced through the hole 44 flows into the vacuum chamber 42 through the through hole 38 and the connection pipe 40.

따라서 대기로부터 유입되는 공기압력에 의해 피스톤(10)은 진공A실(34)쪽으로 이동하게 되고, 따라서 피스톤(10)의 축봉(14)과 연결된 피스톤(16)과 푸쉬로드(18)가 화살표(A)방향으로 이동하면서 로드(20)를 밀게 되므로 로드(20)의 밀리는 힘이 클러치폐달(22)을 시계회전방향으로 밀게되므로 결국 클러치폐달(22)은 축(26)을 중심으로 운전자가 밟는 힘과, 진공 배력장치(가)의 푸쉬로드(18)가 미는 힘이 합체되어 클러치폐달(22)을 작동시키게 되고, 따라서 클러치페달의 답력을 그 만큼 줄일 수 있게 되므로 클러치폐달의 조작이 매우용이하게 이루어지게 된다.Accordingly, the piston 10 moves to the vacuum chamber A 34 due to the air pressure flowing from the atmosphere, so that the piston 16 and the push rod 18 connected to the shaft rod 14 of the piston 10 are moved by arrows ( Since the rod 20 is pushed while moving in the A) direction, the pushing force of the rod 20 pushes the clutch pedal 22 clockwise, so that the clutch pedal 22 is stepped on by the driver about the axis 26. The force and the force pushed by the push rod 18 of the vacuum booster (A) are combined to operate the clutch pedal 22, thus reducing the clutch pedal effort by that much easy operation of the clutch pedal. Will be done.

실린더(4)내에 끼워진 스프링(12)의 탄지력은 진공B실(42)로 유입되는 대기압력보다 탄지력이 약하게 구성되어 있고, 실린더부(8)내에 끼워진 스프링(32)은 대기압력보다 강한 탄지력을 갖는 스프링(32)이 끼워져 있다.The holding force of the spring 12 inserted in the cylinder 4 is configured to be weaker than the atmospheric pressure flowing into the vacuum B chamber 42, and the spring 32 inserted in the cylinder portion 8 is stronger than the atmospheric pressure. A spring 32 having a holding force is fitted.

상기에서와 같이 클러치폐달(22)을 밟고 동력을 전달 혹은 차단한 다음 클러치폐달(22)에 가해졌던 외력을 제거하면 대기압보다 강한 탄지력을 갖는 스프링(32)에 의해 실린더부(8)에 끼워진 피스톤(30)이 먼저 원복하면서 진공A실 (34)과 연결된 출입공(36)을 개방하게 되고, 따라서 진공B실(42)에 충전되어 있던 공기는 연결관(40)및 관통공(38), 출입공(36)을 통하여 진공A실(34)로 유입되고 진공A실(34)로 유입된 공기는 흡기메니홀드 및 진공펌프와 연결된 연결관체(40)를 통하여 배기되므로 실린더(2)내에 끼워진 피스톤(10)이 원복하면서 실린더(2)내에는 다시 진공상태를 유지하게 된다.Stepped on the clutch pedal 22 as described above, and removes the external force applied to the clutch pedal 22, and then inserted into the cylinder portion 8 by a spring 32 having a stronger holding force than atmospheric pressure. The piston 30 first retracts and opens the access hole 36 connected to the vacuum chamber A 34, so that the air filled in the vacuum chamber B 42 is connected to the connection pipe 40 and the through hole 38. The air introduced into the vacuum chamber A (34) through the entrance hole (36) and introduced into the vacuum chamber A (34) is exhausted through the connecting pipe (40) connected to the intake manifold and the vacuum pump. The piston 10 is retracted while maintaining the vacuum in the cylinder 2 again.

본 발명의 진공배력장치를 도3 및 도4, 도5에서와 같이 클러치폐달과 연결하여 사용할 수 있으며 이는 농기계의 구조 및 조건에 따라 선택하여 사용할 수 있다.The vacuum powering device of the present invention can be used in connection with clutch delivery as shown in Figs. 3, 4 and 5, which can be selected and used according to the structure and conditions of agricultural machinery.

따라서 본 발명은 트렉터나 경운기와 같은 농기계를 조작하는 운전자가 클러치폐달을 밟게 되면 운전자가 클러치폐달을 밟는 힘과 진공배력장치에 구성된 푸쉬로드의 미는힘이 동시에 작용하여 클러치폐달을 조작하게 되므로 클러치폐달의 답력을 그 만큼 경감하게 되므로 클러치폐달이 부드럽게 작동하게 되는 등의 효과가 있는 것이다.Therefore, in the present invention, when a driver operating a farm machinery such as a tractor or a cultivator presses the clutch pedal, the driver pushes the clutch pedal and the pushing force of the push rod configured in the vacuum powering device acts simultaneously to operate the clutch pedal. It will reduce the effort of the clutch, so the clutch pedal will work smoothly.
