Description
본 발명은 구동풀리와 종동풀리로 구성되고 원심추의 원심력 즉, 회전속도의 변화에 따라 무단변속이 자동으로 이루어지는 자동무단변속장치에 관한 것이다.The present invention relates to an automatic continuously variable transmission comprising a drive pulley and a driven pulley, and continuously variable speed change according to the centrifugal force of the centrifugal force, that is, the rotational speed.
첨부된 도면 제 1도는 종래의 이륜차에 적용된 무단변속장치의 구동풀리(a)에 대한 단면도로 고정보스(5)의 양 끝단에는 고정풀리(1)와 램프플레이트(6)가 고정되고 이동풀리(2)는 그 회전속도에 따라 고정보스(5)의 외주면(7)을 축방향으로 슬라이딩 가능하게 설치하고 회전속도에 따라 슬라이딩될 수 있도록 하기 위하여 원심력을 발생시키는 원심추(3)와 원심력이 발생하는 방향으로 원심추(3)가 이동할 수 있도록 하는 안내면(4)을 갖고 있다.1 is a cross-sectional view of a drive pulley (a) of a continuously variable transmission that is applied to a conventional two-wheeled vehicle. A fixed pulley (1) and a lamp plate (6) are fixed to both ends of the gobos (5), and a movable pulley ( 2) the centrifugal weight 3 and the centrifugal force generated to generate the centrifugal force in order to slidably install the outer circumferential surface 7 of the high information 5 according to its rotational speed and to be slidable according to the rotational speed It has a guide surface 4 which allows the centrifugal weight 3 to move in the direction to be made.
한편, 첨부된 도면 제 2도는 종래의 이륜차에 적용된 무단변속장치에 종동풀리(b)에 대한 단면도로, 종동풀리(b)도 고정풀리(11)와 이동풀리(12)로 구성되고 이동풀리(12)는 축방향의 힘을 균일하게 분산시키고 벨트(8)의 플래핑 현상을 억제하는 캠 슬롯(13)과 압축 스프링(14)이 구비되어 구동풀리(a)와 종동풀리(b)를 V벨트(8)로 연결하였을 시, 회전에 의해 발생되는 원심력의 변화에 따라 구동풀리(a)가 형성하는 벨트홈(9)의 폭이 변화되고, 이에 연동되어 종동풀리(b)가 형성하는 벨트홈(15)의 폭도 능동적으로 변화되는 자동무단변속장치이다.On the other hand, Figure 2 is a cross-sectional view of the driven pulley (b) in the continuously variable transmission applied to a conventional two-wheeled vehicle, driven pulley (b) also comprises a fixed pulley (11) and a moving pulley (12) and a moving pulley ( 12 is provided with a cam slot 13 and a compression spring 14 for uniformly dispersing the axial force and suppressing the flapping of the belt 8 to drive the drive pulley (a) and the driven pulley (b) V When connected to the belt 8, the width of the belt groove (9) formed by the drive pulley (a) is changed in accordance with the change in the centrifugal force generated by the rotation, the belt formed by the driven pulley (b) in conjunction with this The width of the groove 15 is also an automatic continuously variable transmission.
이와 같은 자동무단변속장치에 사용되는 원심추(3)는 이동시 안내면(4)에 따라 이동하므로 구름운동과 미끄럼운동이 불규칙하게 이루어지며 이것은 회전속도에 따라 이루어지는 무단변속의 정밀성이 떨어지고 원심추(3)의 마모와 소음을 발생시키는 단점이 있으며, 특히 이러한 단점은 낮은 회전속도 즉, 원심력이 작은 상태에서 무단변속이 이루어질 때 더욱 그러하다.Since the centrifugal weight (3) used in such an automatic continuously variable transmission moves along the guide surface (4) during movement, the rolling motion and the sliding motion are irregularly made. This decreases the precision of the continuously variable speed due to the rotational speed and the centrifugal weight (3). ) Has the disadvantage of generating abrasion and noise, in particular, this disadvantage is even more so when the stepless transmission is made at a low rotational speed, that is, a small centrifugal force.
또한, 종동풀리(b) 중 이동풀리(12)에 형성된 캠 슬롯(13)은 종동풀리(b)의 회전방향이 역방향이 되면 벨트(8)의 플래핑 현상을 억제할 수 있는 기능을 할 수 없으므로 이 종동풀리(b)는 양방향 회전으로 무단변속이 요구되는 곳에는 사용할 수 없다.In addition, the cam slot 13 formed in the movable pulley 12 of the driven pulley b may function to suppress flapping of the belt 8 when the rotation direction of the driven pulley b is reversed. Therefore, this driven pulley (b) cannot be used where the stepless speed is required by bidirectional rotation.
이에 대하여 본 발명은 첨부된 도면 제 3도와 제 6도에서 보여주는 바와같이 무단변속의 정밀성을 높이고 원심추(3)의 마모와 소음을 줄일 수 있는 구동풀리(a)와 회전방향이 정방향과 역방향 모두 무단변속이 가능한 종동풀리(b)로 이루어진 자동무단변속장치를 제공하는데 있다.On the other hand, the present invention, as shown in the accompanying drawings 3 and 6, the driving pulley (a) and the direction of rotation that can increase the precision of the stepless speed and reduce the wear and noise of the centrifugal weight (3) both in the forward and reverse directions An automatic continuously variable transmission consisting of a driven pulley (b) capable of continuously variable speed is provided.
