Description
본 발명은 동력분류형 무단변속기에 관한 것으로, 작동부하를 최소화하고 경량, 소형화하여 자전거 또는 오토바이와 같은 소형 동력기기에 적당한 무단 변속기를 제공함으로서 주행중에 동력 단절 없이 동력주입이 가능하며, 변속 조작이 쉽고, 또한 정지 상태에서도 변속이 가능하게 한 것이다.The present invention relates to a power class continuously variable transmission, which minimizes the operating load and provides a continuously variable transmission suitable for a small power device such as a bicycle or a motorcycle by minimizing the operating load, thereby enabling power injection without power loss while driving and shifting operation. It is easy and the shift is possible even in the stationary state.
일반적으로 동력분류형 무단변속기라 함은 입력과 출력 및 자유회전하도록 한 자유도가 주어진 링기어, 캐리어 및 선기어가 1조로 구성되는 유성기어 유닛과 제2의 변속기로서 PIV(벨트식 무단변속기)를 조합하여 무단변속 시 섬세한 속도조절 및 넓은 변속비를 얻기 위한 기구를 칭한다.In general, the power class CVT is a combination of a planetary gear unit consisting of a set of ring gears, a carrier, and a sun gear having a degree of freedom for input, output, and free rotation, and a PIV (belt continuously variable transmission) as a second transmission. It refers to a mechanism for obtaining fine speed control and wide speed ratio during stepless speed change.
상기 유성기어 유닛과 조합되는 PIV는 마찰력에 의한 동력 전달이므로 필요한 마찰력을 얻기 위해서는 구성되는 부품들에 의한 작동부하 및 슬립에 의한 동력 손실이 많으며, 전체적으로 구조가 복잡하고, 효율성이 떨어지는 등의 문제로 인하여 자전거 및 소형 동력기기에 사용할 수가 없었고 중부하용인 중기계나 산업기계 등에만 국한되어 사용되고 있었던 것이다.The PIV combined with the planetary gear unit is a power transmission by the friction force, so in order to obtain the necessary friction force, there is a lot of power loss due to the operating load and the slip due to the components, and the overall structure is complicated and the efficiency is inferior. Therefore, it could not be used for bicycles and small power equipment, and was used only for heavy-duty heavy machinery or industrial machinery.
즉, 상기한 바와 같은 벨트식 무단변속기의 경우 한 쌍의 가변되는 풀리상에 벨트를 결합하고 풀리의 PCD 선상의 변화에 따라서 변속이 이루어 질 수 있도록 한 구성으로서, 고비율의 감속율을 득하기 위해서는 상대적으로 풀리의 크기를 키워야 하고, 이로 인하여 변속기 전체 크기가 커지게 되며, 벨트와 풀리의 면접부위가 넓어지게 되므로 작동부하도 증가하게 되어 중소형에 적용하여 사용하기에는 부적합하였던 것이다.That is, in the case of the belt-type continuously variable transmission as described above, the belt is coupled to a pair of variable pulleys, and the transmission is made according to the change of the PCD line of the pulley. In order to relatively increase the size of the pulley, this increases the overall size of the transmission, and the interview area of the belt and pulley is widened, so that the operating load increases, which is not suitable for use in small and medium-sized.
한편 자전거의 경우 여러장의 체인 스프로켓을 페달에 2~3장, 후륜에 7~8장 겹쳐 놓고 조작레버로 체인을 이동시킬 수 있도록 하여 변속할 수 있도록 한 유단변속기를 채용하고 있으나, 조작레버로 체인을 바꾸는 시점에서 동력주입이 중단되고 변속기의 구조가 복잡하며, 변속조작시 2개의 조작레버를 사용하므로 번거로우며 어느 정도 숙달된 요령이 필요하다.On the other hand, the bicycle uses a stepped gearbox that shifts the chain by splicing two or three chain sprockets on the pedals and seven to eight on the rear wheels so that the chain can be moved with the control lever. At the time of changing power supply, power injection is interrupted and the structure of the transmission is complicated, and it is cumbersome and requires some advanced skills because two operation levers are used for shift operation.
그리고 오토바이의 경우에도 엔진의 R.P.M 에 의한 원심력을 이용한 PIV(벨트식 무단변속기)가 채용되고 있기는 하나, 상기에서 언급한 바와 같이 PIV의 경우부품들에 의한 작동부하 및 슬립에 의한 동력 손실이 많으므로 불필요하게 엔진의 회전수가 올라가므로 연비를 저하시킴은 물론이고 변속 효율이 저감되어, 무단변속기의 장점을 온전히 활용할 수 없으며, 또 소배기량에 한정적으로 이용되고 있는 실정이었다.In the case of motorcycles, the PIV (belt type continuously variable transmission) using centrifugal force by the RPM of the engine is employed, but as mentioned above, in the case of PIV, there is a lot of power loss due to operating load and slip by parts. Therefore, since the engine speed is unnecessarily increased, the fuel efficiency is reduced, as well as the transmission efficiency is reduced, and the advantages of the continuously variable transmission cannot be fully utilized, and the situation is limited to the small displacement.
이에 본 발명에서는 상기한 바와 같은 유성기어 유닛과 제2변속기로서 PIV를 적용한 동력분류형 무단변속기가 가진 해결사안점, 즉, 작동부하의 저하, 경량화, 소형화 하고자 안출한 것이다.Therefore, in the present invention, the planetary gear unit and the power transmission type continuously variable transmission with PIV as the second transmission as described above, to solve the problem, that is, to reduce the operating load, light weight, miniaturized.
본 발명에서는 유성기어 유닛과 요동형 액츄에이트(일명 제로맥스기구)로 구성되는 제2변속기를 조합하여 경량화 및 소형화함은 물론이고 작동부하가 극히 적은 링크를 이용함으로서 작동부하를 현저히 저감할 수 있도록 함으로서, 주행 중에 동력 단절 없이 동력주입이 가능하며, 변속 조작이 쉽고, 또한 정지 상태에서도 변속이 가능한 동력분류형 무단변속기를 제공함에 본 발명의 기술적 과제를 두고 본 발명을 완성한 것이다.In the present invention, a combination of a second transmission composed of a planetary gear unit and a swing type actuator (also known as a zero-max mechanism) can be used to reduce weight and size, as well as to use a link having a very low operating load to significantly reduce operating load. Thus, the present invention has been completed with the technical problem of the present invention to provide a power classification type continuously variable transmission capable of power injection without power interruption during driving, easy shift operation, and shifting even in a stationary state.

즉, 자유도를 갖는 링기어(5)의 회전에 의해 제2변속기(12)의 입력기어(13)가 구동되고, 입력된 회전력은 기어군(16)를 통하여 증속되어 캠기구(17)가 양측으로 대응되게 핀결합된 캠작동기어(22)를 구동하여 회전운동이 직선운동으로 변환 되며, 캠기구(17)에 의해 이루어지는 직선운동은 링크(18)를 통하여 출력축(23)에 축결합된 회동구(25)에 전달되면서 호운동으로 전환되고, 회동구(25) 내측의 일방향클러치(24)에 의해 회전운동으로 복원되어 출력기어(14)를 회전시켜 캐리어(6)에 전달함으로서 무단변속이 이루어지게 된다.That is, the input gear 13 of the second transmission 12 is driven by the rotation of the ring gear 5 having the degree of freedom, and the input rotational force is increased through the gear group 16 so that the cam mechanism 17 is on both sides. The rotational motion is converted into linear motion by driving the cam-operated gear 22 coupled to the pin, and the linear motion made by the cam mechanism 17 is axially coupled to the output shaft 23 through the link 18. It is converted to arc motion while being transmitted to the pupil 25, and restored to rotation by the one-way clutch 24 inside the pivot 25, and the output gear 14 is rotated and transmitted to the carrier 6 so that the stepless speed change is achieved. Will be done.
이때 본 발명에서는 상기 각 캠기구(17)와 링크(18)를 연결하는 핀상에 조작레버(26)에 의해 회동하는 변속조절구(27)에 일단이 핀고정된 링크(19)가 결합되어 캠기구(17)와 링크(18)의 회동폭을 조절하여 출력축(23)의 회전비를 결정할 수 있도록 구성되어 있으므로 출력축(23)으로 회전비를 증감할 수 있게 되는 것이다.At this time, in the present invention, one end of the pin 19 is fixed to the shift control mechanism 27 which is rotated by the operation lever 26 on the pin connecting the cam mechanism 17 and the link 18 to the cam. Since the rotation ratio of the mechanism 17 and the link 18 is adjusted to determine the rotation ratio of the output shaft 23, the rotation ratio can be increased or decreased with the output shaft 23.
일 예로 유성기어유닛(2)의 입력과 출력의 회전비를 1:5로 하고, 제2변속기(12)의 입력과 출력의 회전비도 1:5로 하여, 제2변속기(12)의 작동레버(26)를 도 6a와 같이 조작하여 캠기구(17)와 링크(18)의 연결부에 일단이 핀고정되어 있는 링크(19)의 타단 위치를 하향 이동시키게 되면 링크(18)의 작동폭이 커지게 되어 출력기어(14)가 결합되어 있는 출력축(23)을 회전시키는 회동구(25)의 회동각(Q1)이 커져 회전비를 증가시키게 되므로 페달(4)을 가압하게 되면 링기어(5)를 통해서 입력되는 제2변속기(12)의 출력은 최고치 즉, 5배속으로 증속되어 캐리어(6)에 전달되므로 선기어(7)를 5배속으로 고속 회전시키게 된다.For example, the rotation ratio of the input and output of the planetary gear unit 2 is 1: 5, and the rotation ratio of the input and output of the second transmission 12 is also 1: 5, and the operating lever of the second transmission 12 6A, as shown in FIG. 6A, when the other end position of the link 19, whose one end is pinned to the connecting portion of the cam mechanism 17 and the link 18, is moved downward, the operating width of the link 18 increases. And the rotation angle Q1 of the rotation hole 25 for rotating the output shaft 23 to which the output gear 14 is coupled increases to increase the rotation ratio. Therefore, when the pedal 4 is pressed, the ring gear 5 is pressed. Since the output of the second transmission 12 is increased to the maximum value, that is, 5 times speed and transmitted to the carrier 6, the sun gear 7 is rotated at high speed 5 times.
반대로 작동레버(26)를 조작하여 도 6b에 도시된 바와 같이 링크(19)의 타단 위치를 상향 이동하게되면 상대적으로 링크(18)의 작동폭이 작아지게 되므로 출력기어(14)가 결합되어 있는 출력축(23)을 회전시키는 회동구(25)의 회동각(Q2)이 작아져 회전비를 감소시키게 되므로 페달(4)을 가압하게 되면 링기어(5)를 통해서 입력되는 제2변속기(12)의 출력은 최저치 1배속으로 감속되어 캐리어(6)에 전달되므로 선기어(7)를 1배속으로 저속 회전시키게 되는 바, 본 발명에 의하면 조작레버(26)의 간단한 조작을 통하여 주행 중에 동력 단절 없이 동력주입이 가능하게 되는 것이다.On the contrary, when the operating lever 26 is operated to move the other end position of the link 19 upward as shown in FIG. 6B, the operating width of the link 18 is relatively reduced, so that the output gear 14 is coupled. Since the rotational angle Q2 of the rotational hole 25 for rotating the output shaft 23 is reduced to reduce the rotation ratio, when the pedal 4 is pressed, the second transmission 12 inputted through the ring gear 5 is pressed. Since the output is decelerated at the lowest speed 1x and transmitted to the carrier 6, the sun gear 7 is rotated at low speed at 1x speed. According to the present invention, power injection is performed without power loss during driving through simple operation of the operating lever 26. This will be possible.
이상과 같은 본 발명은 캐리어(6)와 자유도가 주어지는 링기어(5) 및 선기어(7)의 조합으로 이루어지는 유성기어유닛(2)과 요동형 액츄에이트 즉 캠기구(17)와 링크(18)(19) 등으로 구성되는 제2변속기(12)의 간단한 조합으로 고비율의 감속비를 간편하게 조절할 수 있게 되므로 본 발명을 자전거나 오토바이 등에 적용할 경우 종래의 PIV식 변속기에 비하여 마찰저항이 적고, 주행 중에 동력 단절과 같은 종래의 자전거 변속기의 문제점을 해결할 수 있으면서도 구성이 간단하여 저가에 양산이 가능하며 조작성이 간편하게 이루어 질 수 있는 등 기대되는 효과가 상당한 매우 우수한 발명이다.The present invention as described above is a planetary gear unit 2 and a rocking actuator, i.e., a cam mechanism 17 and a link 18, which are composed of a combination of a carrier 6 and a ring gear 5 and a sun gear 7 given a degree of freedom. (19) It is possible to easily adjust the reduction ratio of the high ratio by a simple combination of the second transmission 12 consisting of, etc. When the present invention is applied to a bicycle or motorcycle, the friction resistance is less than the conventional PIV transmission, It is a very excellent invention that can be solved the problems of the conventional bicycle transmission, such as power interruption, while the configuration is simple and mass production at low cost, and the operability can be easily made.
