제2도는 본 발명의 작동 상태를 보인 단면도이다.2 is a cross-sectional view showing an operating state of the present invention.

Recently, research on this has been continuously conducted.
이러한 무단 변속장치는 입력축과 출력축에 장착되는 풀리의 직경변위를 이용하는 방식이 주로 사용되고 있으며, 이의 풀리 직경 변화는 유압을 이용한 축력에 의하여 이루어진다.This continuously variable transmission is mainly used the method of using the diameter displacement of the pulley mounted on the input shaft and the output shaft, the pulley diameter change is made by the axial force using the hydraulic pressure.
그러나 유압을 이용하여 풀리의 직경을 변화시킴에 있어서는 전달되는 토오크에 비례하는 축력을 가해야 하는 바, 풀리의 크기가 커지고, 높은 유압을 생성하기 위한 대용량의 오일펌프를 필요로 한다는 문제점이 있다.However, when changing the diameter of the pulley by using the hydraulic pressure, it is necessary to apply an axial force proportional to the torque transmitted. There is a problem in that the size of the pulley is increased and a large oil pump is required to generate high hydraulic pressure.
또한, 상기와 같이 대용량 오일펌프의 구동에 따른 동력손실로 변속효율이 저하되는 문제점이 있다.In addition, there is a problem that the transmission efficiency is lowered due to the power loss caused by the large-capacity oil pump as described above.
따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로서, 본 발명의 목적은 동력 전달시 발생되는 트러스트에 의해 무단 변속이 이루어지도록하여 구성을 간단히 할 수 있고, 동력손실을 최소화할 수 있도록 한 무단 변속장치를 제공함에 있다.Therefore, the present invention has been invented to solve the above problems, an object of the present invention is to simplify the configuration by making the stepless shift by the trust generated during power transmission, and to minimize the power loss The present invention provides a continuously variable transmission.

이하, 상기의 목적을 구체적으로 실현할 수 있는 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described in detail.
제1도는 본 발명에 의한 실시예의 구성도로서, 부호 2는 동력원으로 엔진이나 기타 구동모터를 예로 들 수가 있다.1 is a configuration diagram of an embodiment according to the present invention, the reference numeral 2 may be an engine or other drive motor as a power source.
상기 동력원(2)의 회전동력은 이의 회전축상에 배치된 구동기어(4)에 의하여 출력이 이루어지는데, 이의 구동기어(4)는 헬리컬 기어로 형성되어 이에 치합되어 있는 제1,2 입력기어(6)(8)에 동력을 전달하게 된다.The rotational power of the power source 2 is output by a drive gear 4 disposed on its rotational axis, the drive gear 4 of which is formed of a helical gear and engaged with the first and second input gears ( 6) (8) to transmit power.
상기 제1,2 입력기어(6)(8)는 구동기어와 마찬가지로 헬리컬 기어로 형성되며, 상기 제1 입력기어(6)는 입력축(10)에 스플라인 결합되어 구동기어(4)의 회전력으로 입력축(10)을 구동시킴과 동시에 축방향 이동이 가능하게 된다.The first and second input gears 6 and 8 are formed of helical gears similarly to the drive gears, and the first input gears 6 are splined to the input shaft 10 and are driven by the rotational force of the drive gear 4. While driving (10), the axial movement is possible.
또한, 상기 제1 입력기어(6)의 반대측에 배치되는 제2 입력기어(6)는 출력측(12)상에 상호 회전 간섭이 발생되지 않는 상태에서 축방향 이동이 가능하도록 구름부재(14)를 개재시켜 결합된다.In addition, the second input gear 6 disposed on the opposite side of the first input gear 6 moves the rolling member 14 to allow the axial movement in the state where mutual rotation interference is not generated on the output side 12. Are interposed.
이에 따라 동력원(2)의 구동에 의하여 구동기어(4)에 구동되면, 이에 연동되는데, 이때 이들 기어(4)(6)(8)가 헬리컬 기어로 형성되는 바, 트러스트의 발생으로 제1,2 입력기어(6)(8)은 상호 반대방향으로 축방향 이동이 이루어진다.Accordingly, when driven to the drive gear 4 by the drive of the power source 2, it is interlocked with these gears, wherein the gears (4), (6) and (8) are formed as helical gears. The two input gears 6 and 8 are axially moved in opposite directions.
그리고 상기 제1,2 입력기어(6)(8)의 일측에는 제1,2 가압부재(16)(18)가 배치되는데, 이의 제1,2 가압부재(16)(18)는 다이어프렘과 같은 디스크 스프링으로 이루어져 그의 외주연이 변속기 하우징(20)에 힌지 고정되고, 내경부가 제1,2 입력기어(6)(8)의 일측단에 지지된다.In addition, first and second pressing members 16 and 18 are disposed at one side of the first and second input gears 6 and 8, and the first and second pressing members 16 and 18 are formed of a diaphragm. Consisting of the same disk spring, its outer circumference is hinged to the transmission housing 20, and the inner diameter portion is supported at one end of the first and second input gears 6 and 8.
물론 상기 제1,2 가압부재(16)(18)의 내경단부와 접촉되는 제1,2 입력기어(6)(8)에는 구름부재(22)(24)가 고착되어 상호 회전 간섭이 발생되지 않도록 하였다.Of course, rolling members 22 and 24 are fixed to the first and second input gears 6 and 8 that are in contact with the inner diameter ends of the first and second pressing members 16 and 18, so that mutual rotation interference does not occur. It was not.
또한, 상기 제1,2 가압부재(16)(18)의 전방에는 구동 및 종동풀리(26)(28)가 배치되는데, 이의 구동 및 종동풀리(26)(28)는 각각 고정풀리(30)(32)와 이동풀리(34)(36)로 이루어져 벨트(38)로서 연결된다.In addition, the driving and driven pulleys 26 and 28 are disposed in front of the first and second pressing members 16 and 18, and the driving and driven pulleys 26 and 28 thereof are fixed pulleys 30, respectively. It consists of a 32 and moving pulleys 34 and 36 and is connected as a belt 38.
상기 고정풀리(30)(32)는 입력축(10)과 출력축(12)에 일체로 형성되며, 이동풀리(34)(36)는 이에 이웃하여 입력축(10)과 출력축(12)상에 축방향 이동가능하도록 배치된다.The fixed pulleys 30 and 32 are integrally formed on the input shaft 10 and the output shaft 12, and the movable pulleys 34 and 36 are adjacent to each other in the axial direction on the input shaft 10 and the output shaft 12. It is arranged to be movable.
그리고 상기 피동풀리(34)(36)의 외주측에는 구름부재(40)(42)이 배치되어 상기 가압부재(16)(18)와 접촉이 이루어진다.And rolling members 40 and 42 are disposed on the outer circumferential side of the driven pulleys 34 and 36 to make contact with the pressing members 16 and 18.
상기에서 구름부재(22)(24),(40)(42)은 축력을 수용할 수 있는 트러스트 베어링이 사용됨은 물론이다.Of course, the rolling members 22, 24, 40 and 42 are used as a thrust bearing that can accommodate the axial force.
이와같이 이루어지는 무단 변속장치의 작용은 구동 및 종동풀리(26)(28)의 직경 가변에 의하여 무단 변속이 이루어지게 되는데, 이들 구동 및 종동풀리(26)(28)의 회전속도 변화조건은, 첫째, 구동풀리(26)와 종동풀리(28)의 외경이 동일할 때와, 둘째 구동풀리(26)의 외경이 종동풀리(28)의 직경보다 큰 경우와, 셋째 구동풀리(26)의 직경이 종동풀리(28)의 직경보다 작은 경우로 나누어 생각할 수 있다.The action of the continuously variable transmission made in this way is made by the variable speed of the drive and driven pulleys (26, 28), the speed change condition of these drive and driven pulleys (26, 28), first, When the outer diameters of the driving pulley 26 and the driven pulley 28 are the same, the outer diameter of the second driving pulley 26 is larger than the diameter of the driven pulley 28, and the diameter of the third driving pulley 26 is driven. It can be considered to divide into a case smaller than the diameter of the pulley 28.
첫째 조건으로 구동 및 종동(26)(28)의 외경이 동일한 경우에는 1:1의 변속비를 갖게 된다.In the first condition, when the outer diameters of the driving and driven 26 and 28 are the same, the transmission ratio is 1: 1.
그리고 둘째로 구동풀리(26)의 외경이 종동풀리(28)의 직경보다 큰 경우에는 구동풀리(26)의 회전수보다 종동풀리(28)의 회전수가 커지기 때문에 증속이 이루어지게 되며, 셋째 구동풀리(26)의 외경이 종동풀리(28)의 직경보다 작아지는 경우에는 구동풀리(26)의 회전수가 종동풀리(28)의 회전수보다 작아지기 때문에 감속이 이루어지게 되는 것이다.And secondly, when the outer diameter of the drive pulley 26 is larger than the diameter of the driven pulley 28, the rotation speed of the driven pulley 28 becomes larger than the rotation speed of the drive pulley 26, so that the speed is increased. When the outer diameter of (26) becomes smaller than the diameter of the driven pulley 28, since the rotation speed of the drive pulley 26 becomes smaller than the rotation speed of the driven pulley 28, deceleration is made.
이러한 변속작용이 이루어지는 구동 및 피동풀리(26)(28)의 작동 일예를 들면, 제2도는 증속이 이루어지는 과정을 도시한 것으로서, 제1도와 같은 1:1의 변속비를 갖는 상태에서 동력원(2)이 구동면서 회전 동력이 출력되면 헬리컬 기어의 특성으로 제1 입력기어(6)는 도면의 좌측으로, 제2 입력기어(8)는 좌측으로 이동하게 된다.For example, FIG. 2 is a diagram illustrating a process of increasing speed, in which the power source 2 is operated in a state where the speed ratio is 1: 1 as shown in FIG. 1. When the rotational power is output while driving, the first input gear 6 moves to the left side of the drawing and the second input gear 8 moves to the left side due to the characteristics of the helical gear.
그러면 제1 입력기어(6)는 가압부재(16)의 내단부를 가압하여 구동풀리(26)의 이동풀리(34)를 밀어주어 풀리의 직경을 크게하고, 제2 입력기어(8)는 가압부재(18)를 가압하던 힘을 해제하게 되므로 이동풀리(36)가 우측으로 이동하면서 직경이 작아지게 되어 증속의 상태로 변속이 이루어지게 되는 것이다.Then, the first input gear 6 presses the inner end of the pressing member 16 to push the moving pulley 34 of the driving pulley 26 to increase the diameter of the pulley, and the second input gear 8 is the pressing member. Since the force that is pressing the 18 is released, the diameter of the moving pulley 36 moves to the right, and the diameter decreases.
상기와 같은 변속과정은 동력원(2)의 회전속도에 따라 트러스트의 크기가 다르게 발생되는 바, 동력원의 속도가 저속일 때에는 감속이 이루어지고, 고속으로 갈수록 증속이 이루어지면서 무단 변속이 이루어지게 되는 것이다.In the shifting process as described above, the size of the thrust is generated differently according to the rotational speed of the power source 2. The speed is reduced when the speed of the power source is low, and the speed is increased as the speed increases. .
도면 중 미설명부호 44은 출력기어이며, 46은 이에 치합되어 있는 트랜스퍼 기어이다.In the drawing, reference numeral 44 denotes an output gear, and 46 denotes a transfer gear engaged with it.
이상에서 설명한 바와 같이 본 발명의 무단 변속장치는 동력 전달시 발생되는 트러스트에 의해 무단 변속이 이루어지도록하여 구성을 간단히 할 수 있고, 동력손실을 최소화할 수 있는 발명인 것이다.As described above, the continuously variable transmission device of the present invention can simplify the configuration by making the continuously variable transmission by a trust generated during power transmission, and minimize the power loss.
