Abstract

PURPOSE: A continuously variable transmission is provided to transmit greater power than a non-stage transmission, which transmits driving power using a belt, and to change torque of driving power output and rotating speed into a linear type because this non-stage transmission uses a chain. CONSTITUTION: A continuously variable transmission includes a rotating disc(1) having a rack gear inside, transmission controllers(B,C) formed by arranging a plurality of combinations of differential gears and chain gears(11) on the rotating disc radially, a link(2) and a link hub(3) for controlling straight motion of the chain gear, and a chain interval controller for allowing a smooth interlocking when the chain gear leaps over a chain at the time of transmission.

Description

무단변속장치{Continuously Variable Transmission}Continuously Variable Transmission

본 발명은 무단변속장치에 관한 것으로, 입력된 동력을 가변출력하며 그 출력 파형이 연속적인 선형으로 나타나는 변속장치이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuously variable transmission, wherein a variable output of input power is provided and its output waveform is continuously linear.

종래에 사용되고 있는 무단변속장치는 벨트와 가변벨트풀리를 이용하고 있다. 그러나 이러한 무단변속장치는 큰 동력을 전달하기 어려우며, 급진적인 동력전달도 어려운 문제점을 갖고 있다.The continuously variable transmission used in the related art uses a belt and a variable belt pulley. However, such a continuously variable transmission is difficult to transmit a large amount of power, and radical power transmission has a problem.

본 발명은 상기와 같은 문제점을 해결하기 위하여 벨트와 가변 벨프풀리 대신에 체인과 차동기어장치를 사용하여 큰 동력을 전달하고 급진적인 동력전달을 할 수 있는 무단변속장치를 제공하는데 그 목적이 있다.An object of the present invention is to provide a continuously variable transmission capable of transmitting large power and radical power transmission by using a chain and a differential gear device instead of a belt and a variable valve pulley in order to solve the above problems.

상기한 바의 목적을 달성하기 위해서 차동기어장치에 체인기어를 결합한 다수 개를 회전원판에 방사형태로 설치하고 회전원판의 중심을 기준으로 오므라졌다, 펴졌다할 수 있게 하여 다수 개의 차동기어장치에 설치된 체인기어들이 만들어 내는 피치원 직경이 가변될 수 있게하였다. 이렇게 설치된 회전원판을 2개 조립하여 프레임에 직렬로 배치하고, 각각의 회전판에 설치된 다수개의 체인기어들이 만들어 내는 피치원 직경값을 서로 반비례되게 한다.In order to achieve the above object, a plurality of the chain gears coupled to the differential gear device are radially installed on the rotating disc, and then retracted from the center of the rotating disc so that they can be unfolded. The pitch circle diameter produced by the installed chain gears can be varied. Thus assembled two rotating discs are arranged in series on the frame, and the pitch circle diameter values generated by a plurality of chain gears installed on each rotating plate are inversely proportional to each other.

이것은 길이가 일정한 체인이 변속시 남아도는 일이 없으며, 변속비를 극대화 시키는 효과를 준다. 또한 변속시 피치가 일정한 체인과 체인기어간에 발생되는 피치값의 변화를 보정하기 위해서 체인간격조절기를 설치하여 변속시에도 체인과 체인기어가 잘 맞물릴 수 있도록하였다.This ensures that chains of constant length do not remain in the shift, maximizing the gear ratio. In addition, in order to compensate for the change in the pitch value generated between the chain and the chain gear with a constant pitch during shifting, a chain spacing regulator was installed so that the chain and the chain gear could be meshed well during shifting.

따라서, 본 발명의 이러한 구조는 벨트가 아닌 체인을 이용하여 동력을 변속하므로 동력전달시 미끄럼현상이 발생하지 않으며 비교적 큰 동력을 전달할 수 있는 장점을 갖는다.Therefore, this structure of the present invention has the advantage that can be transmitted relatively large power without the sliding phenomenon occurs during power transmission because the power is changed using a chain rather than a belt.

이하, 본 발명의 실시예를 도시한 첨부 도면을 참조하여 그 구성과 작용을 상세히 설명한다.Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in detail the configuration and operation.

제 1도는 본 발명에 따른 변속조절기의 조립도이다. 제 1도에서 보이는바와 같이 2개의 회전원판(1) 사이에 다수 개의 차동기어장치(A)를 방사형태로 배열하였으며, 다수 개의 차동기어장치(A)는 링크(2)와 링크허브(3)에 핀 결합되어 있다. 이것은 각각의 차동기어장치가 펴지거나 오무라질 때 그 이동거리를 같게 할 수 있다. 변속시 변속조절기(B)에 설치된 다수 개의 체인기어(11)들이 이루는 피치원 직경값과 변속조절기(C)에 설치된 다수 개의 체인기어(11)들이 이루는 피치원직경 값은 각각 반비례하여 작동된다. 즉, 변속조절기(B)의 체인기어(11)들이 이루는 피치원직경값이 커질 때에는 변속조절기(C)의 체인기어(11)들이 이루는 피치원직경값은 작아진다. 반대로 변속조절기(C)의 체인기어(11)들이 이루는 피치원 직경값이 커질 때에는 변속조절기(B)의 체인기어(11)들이 이루는 피치원 직경값은 작아진다. 제2도와 제3도는 차동기어장치(A)의 구조를 나타낸다. 차동기어장치의 양쪽 축(4)에는 체인기어(11)가 고정 설치되며 제7도는 차동기어장치(A)와 체인기어(11)가 조립된 확대도이다. 제4도는 변속조절기의 내부를 나타낸다. 차동기어장치(A)의 평기어(5)는 회전원판(1)의 내부에 부착된 랙기어(8)과 맞물려 움직인다. 제5도는 체인간격조절기(F)이며 그림에서 보는 바와 같이 체인기어(9,10)가 구비되어 있을 때 체인이 모여지기 시작하는 부분 즉, "D"부분에서 가상체인(E)가 차지하는 공간을 형성시켜 그 간격을 일정하게 유지시켜주는 역할을 한다. 이것은 체인기어(11)이 체인과 체인사이를 건너서 회전할 때 충격을 감소시켜주는 역할을 한다. 제 6도는 변속조절기(B,C)사이에 설치된 체인간격조절기(F)를 나타낸다.1 is an assembly view of a shift controller according to the present invention. As shown in FIG. 1, a plurality of differential gear devices A are radially arranged between two rotating discs 1, and the plurality of differential gear devices A is a link 2 and a link hub 3, respectively. Is coupled to the pin. This allows the same travel distance as each differential gear is extended or collapsed. The pitch circle diameter value formed by the plurality of chain gears 11 installed in the shift controller B and the pitch circle diameter value formed by the plurality of chain gears 11 installed in the shift controller C are operated in inverse proportion to each shift. That is, when the pitch circle diameter values of the chain gears 11 of the shift controller B become large, the pitch circle diameter values of the chain gears 11 of the shift controller C become small. On the contrary, when the pitch circle diameter values of the chain gears 11 of the shift controller C become large, the pitch circle diameter values of the chain gears 11 of the shift controller B become small. 2 and 3 show the structure of the differential gear device A. As shown in FIG. Chain gears 11 are fixedly installed on both shafts 4 of the differential gear device, and FIG. 7 is an enlarged view in which the differential gear device A and the chain gear 11 are assembled. 4 shows the inside of the shift controller. The spur gear 5 of the differential gear device A is engaged with the rack gear 8 attached to the inside of the rotating disc 1. 5 is a chain spacing controller (F), and as shown in the figure, when the chain gears (9, 10) are provided, the space where the virtual chain (E) occupies the space where the chain starts to gather, that is, the "D" portion. It forms and keeps the gap constant. This serves to reduce impact when the chain gear 11 rotates between the chain and the chain. 6 shows a chain spacing controller F installed between the shift controllers B and C.

이상과 같이 구성된 본 발명의 변속장치는 링크허브(3)을 축 방향으로 이동시킴으로써 입력된 동력을 연속적으로 가변 출력할 수 있는 무단변속장치의 기능을 갖는다.The transmission of the present invention configured as described above has the function of a continuously variable transmission that can continuously output the input power by moving the link hub 3 in the axial direction.

이상에서 설명한 바와 같은 본 발명에 따른 무단변속장치는 체인을 사용하기 때문에 벨트를 이용하여 동력을 전달하는 무단변속장치보다 비교적 큰 힘을 전달 할 수 있으며, 또한 출력되는 동력의 토크와 회전속도가 선형적으로 변화되는 무단변속장치이다.Since the continuously variable transmission according to the present invention as described above uses a chain, it can transmit a relatively larger force than the continuously variable transmission that transmits power using a belt, and the torque and rotation speed of the output power are linear. It is a continuously variable transmission.
