본 발명은 구동축의 크랭크 부분을 꺽임 구성으로 만들어서 크랭크축 옆에 설치한 유압실린더로된 가변작동 장치를 통해 꺽임축의 꺽임각도를 필요에 맞도록 의도적으로 변화시킴으로써 크랭크축의 원주속도가 가감될 수 있게한 무단형변속장치에 관한 것이다.The present invention by making the crank portion of the drive shaft in a bent configuration by intentionally changing the bend angle of the bent shaft through a variable operating device made of a hydraulic cylinder installed next to the crankshaft so that the circumferential speed of the crankshaft can be added or subtracted. It relates to a continuously variable transmission.

종래의 변속기는 대부분의 경우 크고적은 다수의 감속 기어나 푸울리의 조합으로 구동축의 회전속도를 변경시키는 것이므로 변속효과가 단계적으로 되는 불편이 있고 구조도 매우 복잡해지는 등의 어려움이 있었다.In the conventional transmission, since the rotation speed of the drive shaft is changed by a combination of a plurality of reduction gears or a pulley, in many cases, the transmission effect is inconvenient, and the structure is very complicated.

본 발명은 위와같은 종래의 결점을 시정하기 위하여 발명된 것으로 첨부도면에 의거 보다 상세히 설명하면 다음과 같다.The present invention has been invented to correct the above conventional drawbacks and will be described in more detail based on the accompanying drawings.

구동축(6)의 끝과 연결되어 회전될 수 있도록 된 두개의 크랭크축(1), (2)을 일직선상에 설치한 축관(7), (7a)에 끼워 장치하고 각자의 크랭크축은 내측단에 각각 접속부(1a), (2a)를 형성하여 이곳에 각각 같은 길이로되고 내측으로 접촉홈이 구비된 연결축(1가), (1나)의 외측단을 연결핀(4)으로 연결하고 두 연결축(1가), (1나)의 내측접속부에는 크랭크축의 양단 접속부(3a)와 연결핀(4a)으로 연결시키고 각 크랭크(3)에는 같은 길이의 크랭크로-드(5)를 접속시키고 크랭크축과 나란한 측방으로는 일직선상에 축잡이(18), (18a)를 장치하여 분할된 작동축(10), (11)을 끼워 접속부(10a), (11a)에 꺽임연결축(12), (13)의 외측접속부(12b), (13b)를 연결핀(14), (14a)으로 접속시키고 두 꺽임연결축(12), (13)의 내측 접속부(12b), (13a)는 하나의 연결핀(15)으로 연결한후 연결핀 양단에 유체압실린더로 된 작동자(17)의 작동로-드(17a) 연결부(16)를 접속시켜 두 작동축(10), (11)의 축설부 외면과 크랭크축(7), (7a) 사이를 연결관(9), (9a)으로 연결시켜서 일련의 구성이 형성되게한 장치이다.Two crank shafts (1) and (2), which are connected to the end of the drive shaft (6) and can be rotated, are fitted to the shaft tubes (7) and (7a) installed in a straight line. The connecting portions 1a and 2a are formed to connect the outer ends of the connecting shafts 1a and 1b, which have the same length and are provided with contact grooves, respectively. The inner connecting portion of the connecting shaft (1) and (1) is connected to both ends of the crankshaft connecting portion 3a and the connecting pin 4a, and the cranks 3 of the same length are connected to each crank 3, respectively. Side-by-side parallel to the crankshaft, the connecting shafts 12 are connected to the connecting portions 10a and 11a by inserting the operating shafts 10 and 11, which are divided by mounting the shaft holders 18 and 18a in a straight line. , The outer connecting portions 12b and 13b of (13) are connected with connecting pins 14 and 14a, and the inner connecting portions 12b and 13a of the two bending connecting shafts 12 and 13 are one. The connection pins (15) of the The connecting rod 16 of the actuator 17 of the cylinder 17 is connected to connect the outer surface of the accumulators of the two operating shafts 10 and 11 with the crank shafts 7 and 7a. It is a device connected to the pipes 9 and 9a to form a series of configurations.

이와같이된 본 발명은 작동자(17)를 가동시켜 그 작동로-드(17a)을 실린더 내측으로 당기면 꺽임 연결축(12), (13)의 내측 접속부(12b), (13b)가 꺽이면서 두 작동축(10), (11)이 길이 방향으로 내향 이동하고 동시에 연결관(9), (9a)을 통해 연결된 크랭크축 축잡이(7), (7a)가 서로 내향하여 축간거리가 짧아지므로 두 연결축(1가), (1나)이 굴절되게되어 크랭크축(1), (2)의 중심선에서 크랭크(3)가 편향되는 작동이 일어나고 이때 구동축(6)을 통해 전달된 동력이 크랭크축(1), (2)을 회전시키면 크랭크축의 중심에 크랭크가 있을때 보다 크랭크축의 원주가 커지게 되어 원주속도를 변화시킬 수 있기 때문에 구동축의 속도가 일정한 상태에서 크랭크축의 원주속도를 무단으로 변경시킬 수 있어 변속효과를 얻을 수 있기 때문에 작동자(7)의 작동로-드(17a)를 통해 작동축(10), (11)의 꺽임 연결축(12), (13)을 꺽는 각도에 따라 크랭크축(1), (2)의 크랭크 원주속도를 변경시킬 수 있어 고품위의 변속장치를 얻을 수 있기 때문에 복잡한 변속기어를 사용하지 않고 동력부의 회전속도가 일정한 범위내에서 상당한 무단계의 출력 속도가변이 가능한 변속장치를 만들 수 있는 것이다.According to the present invention as described above, when the operator 17 is operated and the operation rod 17a is pulled into the cylinder, the inner connecting portions 12b and 13b of the bending connecting shafts 12 and 13 are bent. Since the working shafts 10 and 11 move inward in the longitudinal direction and the crankshaft shaft holders 7 and 7a connected through the connecting pipes 9 and 9a at the same time are inward, the distance between the shafts is shortened. The linking shafts 1a and 1b are deflected so that the crank 3 is deflected at the center lines of the crankshafts 1 and 2, and the power transmitted through the drive shaft 6 is the crankshaft. By rotating (1) and (2), the circumference of the crankshaft becomes larger than when the crank is in the center of the crankshaft, so that the circumferential speed can be changed. Therefore, the circumferential speed of the crankshaft can be changed without permission. In order to obtain a shifting effect through the operating rod-17a of the operator 7 The crank circumferential speed of the crankshafts (1) and (2) can be changed according to the angle of bending the connecting shafts (12) and (13) of the), so that a high-quality transmission can be obtained. In addition, it is possible to make a transmission that can change a considerable stepless output speed within a constant range of a power unit.
