본 발명은 이륜차용 무단자동 변속장치에 관한 것으로, 보다 상세하게는 자전거나 오토바이크 등의 이륜차의 구동축과 피동축에 장착되어 구동벨트를 통해 가해지는 구동력과 전류과 후륜에 각각 가해지는 하중의 변화에 따라 자동적으로 무단 변속구동하는 이륜차용 무단자동 변속장치에 관한 것이다.The present invention relates to a continuously variable transmission device for a two-wheeled vehicle, and more particularly, it is mounted on a drive shaft and a driven shaft of a two-wheeled vehicle such as a bicycle or motorcycle, and is applied to the driving force and current applied through the drive belt and the change in the load applied to the rear wheels, respectively. The present invention relates to a continuously variable automatic transmission for a two-wheeled vehicle that is automatically driven in a continuously variable speed according to the present invention.

도 1 및 도 2에는 종래기술에 따른 무단자동 변속 장치의 구성이 개시되어 있다. 도면을 참고하면 종래의 무단자동 변속 장치는, 중앙에 관통삽입된 페달축(10)에 고정되어 함께 회전하는 제1고정판(110)과, 상기 제1고정판(110)의 측방에 대향배치되며 중앙에 관통삽입된 페달축(10)을 중심으로 자유회전하는 제1회동판(120) 및, 상기 제1고정판(110)에 장착된 제1핀(111)을 축으로 일단이 회동가능하게 장착되는 구동암(131)과, 상기 제1회동판(120)에 장착된 제2핀(121)을 축으로 일단이 회동가능하게 장착되는 제1지지암(132) 및, 상기 구동암(131)의 타단과 제1지지암(132)의 타단이 회동가능하게 장착되는 제1받이(133)를 포함하며 상기 페달축(10)을 중심으로 하는 원주상에서 대향배치되는 두 개의 구동풀리부(130)를 포함하는, 전방변속부(100); 상기 전방변속부(100)의 후방 위치에 배치되어 후륜축(20)에 장착되는 후방변속부(200); 및 링형상으로 형성되어 상기 전방변속부(100)와 후방변속부(200) 사이에 연결되면서 구동력을 전달하는 동력전달부재(300);를 포함하여 구성되었다.1 and 2, the configuration of the continuously variable automatic transmission according to the prior art is disclosed. Referring to the drawings, the conventional continuously variable transmission device includes a first fixing plate 110 fixed to a pedal shaft 10 inserted through the center and rotating together, and disposed opposite to the side of the first fixing plate 110 and disposed in the center One end is rotatably mounted about the first rotating plate 120 and the first pin 111 mounted on the first fixing plate 110, which is freely rotated about the pedal shaft 10 inserted through the A driving arm 131 , a first support arm 132 , one end of which is rotatably mounted about a second pin 121 mounted on the first rotation plate 120 , as an axis, and the driving arm 131 . The other end and the other end of the first support arm 132 are rotatably mounted to the first receiving end 133 , and two driving pulley units 130 opposite to each other on a circumference centered on the pedal shaft 10 are provided. Including, the front derailleur 100; a rear derailleur 200 disposed at a rear position of the front derailleur unit 100 and mounted on the rear wheel shaft 20; and a power transmission member 300 formed in a ring shape and connected between the front transmission part 100 and the rear transmission part 200 to transmit a driving force.

따라서, 전방변속부(100)는 상기 제1받이(133)가 동력전달부재(300)를 지지하면서 가해지는 하중변화에 따라 상기 구동암(131)이 회동하여 제1받이(133)의 회전반경이 조절되도록 변속구동할 수 있었다.Accordingly, in the front transmission part 100 , the driving arm 131 rotates according to a change in the load applied while the first receiving 133 supports the power transmission member 300 , and the rotation radius of the first receiving unit 133 . It could be shifted to adjust this.

그러나, 종래의 무단자동 변속 장치는 제1구동암(132)과 제1지지암(132)이 서로 다른 방향에서 경사지게 배치되며 두 암 중 제1구동암(132)에만 회전구동력이 작용하여 과도한 구동력이 가해지는 경우 제1지지암(132)측으로 휘어지거나 심한 경우 파손되는 경우가 발생할 수 있었다.However, in the conventional continuously variable automatic transmission device, the first driving arm 132 and the first support arm 132 are inclined in different directions, and the rotational driving force is applied only to the first driving arm 132 of the two arms, resulting in excessive driving force. When this is applied, it may be bent toward the first support arm 132 or, in severe cases, may be damaged.

또한, 도 3에 도시된 바와 같이 동력전달부재(300)는 하부로 갈수록 폭이 좁아지는 형태로 이루어지고 제1받이(133)의 상향 개구된 받이홈(136)에 삽입된 상태에서 두 부재간의 마찰력에 의해 구동력이 전달되도록 구비되나, 두 부재 사이에 먼지나 수분 등의 이물질이 끼거나 과도한 구동력이 가해지는 경우 슬립이 발생하여 구동력이 손실되는 문제점이 있었다.In addition, as shown in FIG. 3 , the power transmission member 300 has a shape that becomes narrower toward the lower part and is inserted into the receiving groove 136 that is opened upward of the first receiving member 133 between the two members. Although it is provided so that the driving force is transmitted by the frictional force, there is a problem in that when foreign substances such as dust or moisture are caught between the two members or when an excessive driving force is applied, slip occurs and the driving force is lost.
