Description

무단변속기{CONTINUOUSLY VARIABLE TRANSMISSION}CONTINUOUSLY VARIABLE TRANSMISSION}

본 발명은 무단변속기에 관한 것으로서, 자성에 따른 액체의 점도 변화로 최적 변속 타이밍을 제공하여 상품성을 향상시키고 효율을 개선할 수 있는 무단변속기에 관한 것이다.The present invention relates to a continuously variable transmission, which can improve marketability and efficiency by providing optimal shift timing by changing the viscosity of liquid due to magnetism.

일반적으로 엔진이나 모터와 같은 회전력발생수단을 이용하는 다양한 종류의 기계장치에는 적절한 크기의 회전속도와 토크를 얻기 위해 변속기를 이용하는 경우가 많다. 이러한 변속기는 수동변속기와 자동변속기로 대별될 수 있으며, 현재는 자동변속기가 널리 사용되고 있는 추세이다.In general, various types of mechanical devices that use rotational force generation means such as engines or motors often use a transmission to obtain an appropriate rotational speed and torque. These transmissions can be roughly divided into manual transmissions and automatic transmissions, and automatic transmissions are currently being widely used.

자동변속기의 종류는 다양한데, 그 중 무단변속기는 구동풀리와 종동풀리를 벨트로 연결하여 동력이 전달되도록 구성된다. 따라서 벨트 전동방식의 무단변속기는 동력전달이 직결되므로 엔진이나 모터와 같은 회전력발생수단의 출력 활용도가 높고, 다른 방식의 자동변속기보다 구조가 간단하며 경량이고, 변속충격이 발생되지 않으므로 정숙성이 높다는 등의 장점을 갖는다.There are various types of automatic transmissions, among which the continuously variable transmission is configured to transmit power by connecting the driving pulley and driven pulley with a belt. Therefore, since the belt-driven continuously variable transmission is directly connected to power transmission, the output utilization of rotational force generating means such as an engine or motor is high, the structure is simpler and lighter than other automatic transmission types, and it is quiet because no shifting shock occurs. has the advantage of

그러나, 이러한 장점들에도 불구하고, 벨트 전동방식의 무단변속기는 유압식으로 변속비를 조절하므로 변속을 위한 반응속도가 느리고, 효율이 떨어지는 문제점이 있다. 따라서, 이를 개선할 필요성이 요청된다.However, despite these advantages, the belt-driven continuously variable transmission has the problem of slow response speed for shifting and low efficiency because the transmission ratio is controlled hydraulically. Therefore, there is a need to improve this.

In this process, the thickness of lines or sizes of components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are terms defined in consideration of functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, definitions of these terms should be made based on the content throughout this specification.

도 1은 본 발명의 일 실시예에 따른 무단변속기를 개략적으로 나타내는 도면이고, 도 2는 본 발명의 일 실시예에 따른 전달부의 무단변속 상태를 개략적으로 나타내는 도면이다. 도 1과 도 2를 참조하면, 본 발명의 일 실시예에 따른 무단변속기(1)는 입력부(10)와, 출력부(20)와, 전달부(30)와, 유도부(40)를 포함한다.Figure 1 is a diagram schematically showing a continuously variable transmission according to an embodiment of the present invention, and Figure 2 is a diagram schematically showing a continuously variable transmission state of a transmission unit according to an embodiment of the present invention. Referring to FIGS. 1 and 2, the continuously variable transmission 1 according to an embodiment of the present invention includes an input unit 10, an output unit 20, a transmission unit 30, and an induction unit 40. .

입력부(10)는 일측으로 외주면이 점점 줄어드는 테이퍼진 형상을 하여 회전된다. 일예로, 입력부(10)는 엔진과 연결되고, 좌측으로 갈수록 지름이 줄어들며, 길이 방향으로 홈이 형성되는 기어형상을 할 수 있다. The input unit 10 is rotated to have a tapered shape in which the outer peripheral surface gradually decreases on one side. For example, the input unit 10 is connected to the engine, and may have a gear shape with a diameter that decreases toward the left and a groove formed in the longitudinal direction.

출력부(20)는 입력부(10)와 마주보도록 배치되고, 타측으로 외주면이 점점 줄어드는 테이퍼진 형상을 하여 회전된다. 일예로, 출력부(20)는 바퀴에 구동력을 제공할 수 있으며, 우측으로 갈수록 지름이 줄어들고, 길이 방향으로 홈이 형성되는 기어형상을 할 수 있다. 출력부(20)는 입력부(10)와 180도 대칭되는 형상을 할 수 있다.The output unit 20 is arranged to face the input unit 10, and is rotated to the other side in a tapered shape with its outer peripheral surface gradually decreasing. For example, the output unit 20 may provide driving force to a wheel, and may have a gear shape in which the diameter decreases toward the right and a groove is formed in the longitudinal direction. The output unit 20 may have a shape that is 180 degrees symmetrical to the input unit 10.

전달부(30)는 입력부(10)와 출력부(20)에 감기고, 입력부(10)의 회전력을 출력부(20)에 전달한다. 일예로, 전달부(30)는 입력부(10) 및 출력부(20)와 맞물리고 수평으로 이동되면 출력부(20)로 전달하는 변속비가 달라질 수 있다. 전달부는 링 형상을 하는 벨트 내측으로 돌기가 돌출되어 입력부(10)와 출력부(20)의 홈에 삽입될 수 있다. 이로 인해 전달부(30)가 좌우 이동되더라도 입력부(10) 및 출력부(20)와 맞물린 상태를 유지하므로, 변속비가 달라지면서 입력부(10)의 회전력을 출력부(20)로 전달할 수 있다.The transmission unit 30 is wound around the input unit 10 and the output unit 20, and transmits the rotational force of the input unit 10 to the output unit 20. For example, when the transmission unit 30 engages with the input unit 10 and the output unit 20 and moves horizontally, the transmission ratio transmitted to the output unit 20 may vary. The transmission unit has protrusions protruding from the inside of the ring-shaped belt and can be inserted into the grooves of the input unit 10 and the output unit 20. Because of this, even if the transmission unit 30 is moved left or right, it remains engaged with the input unit 10 and the output unit 20, so the rotational force of the input unit 10 can be transmitted to the output unit 20 while the transmission ratio changes.

유도부(40)는 전달부(30)를 수평 이동시켜 무단 변속을 유도한다. 일예로, 1개의 유도부(40)가 입력부(10)의 상방 또는 출력부(20)의 하방에 배치되어 전달부(30)와 연결될 수 있다. 그 외, 2개의 유도부(40)가 입력부(10)의 상방과출력부(20)의 하방에 배치되어 전달부(30)와 연결되어도 무방하다.The induction unit 40 moves the transmission unit 30 horizontally to induce continuously variable shifting. For example, one induction unit 40 may be disposed above the input unit 10 or below the output unit 20 and connected to the transmission unit 30. In addition, two induction units 40 may be disposed above the input unit 10 and below the output unit 20 and connected to the transmission unit 30.

도 3은 본 발명의 일 실시예에 따른 유도부를 개략적으로 나타내는 도면이다. 도 3을 참조하면, 본 발명의 일 실시예에 따른 유도부(40)는 유도하우징부(41)와, 유도이동부(42)와, 유도회전부(43)와, 유도작동부(44)를 포함한다.Figure 3 is a diagram schematically showing an induction unit according to an embodiment of the present invention. Referring to Figure 3, the induction unit 40 according to an embodiment of the present invention includes an induction housing part 41, an induction moving part 42, an induction rotation part 43, and an induction operation part 44. .

유도하우징부(41)는 차체에 고정 설치된다. 일예로, 유도하우징부(41)는 내부가 비워지고 일측이 개구된 원통 형상을 하는 하우징몸체부(411)와, 하우징몸체부(411)의 개구된 부분을 커버하는 하우징커버부(412)를 포함할 수 있다. 하우징커버부(412)는 하우징몸체부(411)에 나사 조립될 수 있다.The induction housing portion 41 is fixedly installed on the vehicle body. For example, the induction housing portion 41 includes a housing body portion 411 that has a cylindrical shape with an empty interior and an opening on one side, and a housing cover portion 412 that covers the opened portion of the housing body portion 411. It can be included. The housing cover portion 412 may be screw-assembled to the housing body portion 411.

유도이동부(42)는 유도하우징부(41)에 내장된다. 일예로, 유도하우징부(42)는 유도이동부(42)의 내측에 밀착되어 유도하우징부(41)를 제1챔버부(91)와 제2챔버부(92)로 구획할 수 있다. The guided movement part 42 is built into the guided housing part 41. For example, the induction housing part 42 may be in close contact with the inside of the induction moving part 42 to divide the induction housing part 41 into a first chamber part 91 and a second chamber part 92.

유도회전부(43)는 유도이동부(42)에 연결되어 회전 가능하고, 전달부(30)가 감긴다. 일예로, 유도회전부(43)는 유도하우징부(41)를 관통하여 외부에 노출되고, 전달부(30)와 맞물려 회전될 수 있다.The inductive rotating part 43 is connected to the inductive moving part 42 and can rotate, and the transmission part 30 is wound around it. For example, the induction rotating part 43 penetrates the induction housing part 41 and is exposed to the outside, and may engage with the transmission part 30 and rotate.

유도작동부(44)는 유도하우징부(41)와 유도이동부(42) 사이에 배치되고, 전원의 인가 여부에 따라 유도이동부(42)를 이동시킨다. 일예로, 유도작동부(44)는 제1챔버부(91)에 충진되고, 전원이 인가되면 배치 및 점도의 변화에 따라 유도이동부(42)를 밀어내어 유도회전부(43)를 이동시킬 수 있다.The inductive actuating part 44 is disposed between the inductive housing part 41 and the inductive moving part 42, and moves the inductive moving part 42 depending on whether or not power is applied. For example, the inductive actuating part 44 is filled in the first chamber part 91, and when power is applied, the inductive rotating part 43 can be moved by pushing the inductive moving part 42 according to changes in arrangement and viscosity. .

보다 구체적으로, 유도회전부(43)는 회전막대부(431)와 회전기어부(432)를 포함한다. More specifically, the induction rotating part 43 includes a rotating rod part 431 and a rotating gear part 432.

회전막대부(431)는 유도이동부(42)에 결합되고 유도하우징부(41)를 관통한다. 일예로, 회전막대부(431)는 하우징커버부(412)를 관통하여 외부로 노출될 수 있다.The rotating rod part 431 is coupled to the guided moving part 42 and penetrates the guided housing part 41. For example, the rotating rod portion 431 may penetrate the housing cover portion 412 and be exposed to the outside.

회전기어부(432)는 회전막대부(431)에 회전 가능하도록 장착되고, 전달부(30)와 맞물린다. 일예로, 회전기어부(432)는 회전막대부(431)의 단부에 결합되되, 내주면에 베어링이 구비되어 회전막대부(431)의 단부에서 회전될 수 있다. 회전기어부(432)의 외주면에는 돌기와 홈이 번갈아 형성되어 전달부(40)와 맞물릴 수 있다.The rotation gear unit 432 is rotatably mounted on the rotating rod unit 431 and engages with the transmission unit 30. For example, the rotation gear unit 432 is coupled to the end of the rotating rod unit 431, and is provided with a bearing on the inner peripheral surface so that it can rotate at the end of the rotating rod unit 431. Protrusions and grooves are alternately formed on the outer peripheral surface of the rotary gear unit 432 to engage with the transmission unit 40.

유도작동부(44)는 작동유체부(441)와 작동조절부(442)를 포함한다.The inductive operation unit 44 includes an operating fluid unit 441 and an operation control unit 442.

작동유체부(441)는 유도하우징부(41)에 주입되고 자성체를 구비한다. 일예로, 작동유체부(441)는 자성체 조각을 포함하는 고분자 액체가 될 수 있다. The working fluid portion 441 is injected into the induction housing portion 41 and includes a magnetic material. For example, the working fluid portion 441 may be a polymer liquid containing a piece of magnetic material.

작동조절부(442)는 유도하우징부(41)에 감기고, 전원이 인가됨에 따라 유도이동부(42)를 밀어내도록 작동유체부(441)를 변형시킨다. 일예로, 마그네틱 코일이 하우징몸체부(411)의 외측에 감기고, 마그네틱 코일에 전원이 인가되면 형성되는 자기력에 의해 자성체 조각의 배치 상태가 변경될 수 있다. 그 외, 작동조절부(442)에 전원이 인가됨에 따라 작동유체부(441)의 부피가 증가하여 유도이동부(42)를 밀어낼 수 있다.The operation control unit 442 is wound around the induction housing unit 41, and deforms the operating fluid unit 441 to push the induction moving unit 42 as power is applied. For example, when a magnetic coil is wound around the outside of the housing body portion 411 and power is applied to the magnetic coil, the arrangement of the magnetic pieces may be changed by the magnetic force formed. In addition, as power is applied to the operation control unit 442, the volume of the operating fluid unit 441 increases and the guided movement unit 42 can be pushed out.

한편, 작동유체부(441)는 복수개의 구간으로 구분될 수 있으며, 이들 구간에는 전원이 인가됨에 따라 변형되는 변형율이 다르도록 자성체 조각의 형상이나 비율이 달라질 수 있다. 이로 인해 각 구간별로 전원이 선택적으로 인가됨에 따라 유도이동부(42)의 길이 조절이 보다 정밀하게 이루어질 수 있다.Meanwhile, the working fluid unit 441 may be divided into a plurality of sections, and the shape or ratio of the magnetic material pieces may vary in these sections so that the deformation rate is different as power is applied. As a result, the length of the guided movement unit 42 can be adjusted more precisely as power is selectively applied to each section.

본 발명의 일 실시예에 따른 유도부(40)는 유도복원부(45)를 더 포함할 수 있다. 유도복원부(45)는 유도하우징부(41)에 내장되고, 유도이동부(42)에 복원력을 제공한다. The induction unit 40 according to an embodiment of the present invention may further include an induction restoration unit 45. The induction restoration part 45 is built into the induction housing part 41 and provides a restoring force to the induction moving part 42.

일예로, 유도복원부(45)는 코일스프링 형상을 하고, 유도이동부(42)와 하우징커버부(412) 사이에 배치되어 유도이동부(42)를 탄성 지지할 수 있다. 즉, 유도이동부(42)의 좌측에 형성되는 제1챔버부(91)에는 작동유체부(441)가 충진되고, 유도이동부(42)의 우측에 형성되는 제2챔버부(92)에는 유도복원부(45)가 배치될 수 있다.For example, the inductive restoration unit 45 has a coil spring shape and is disposed between the inductive moving part 42 and the housing cover part 412 to elastically support the inductive moving part 42. That is, the first chamber part 91 formed on the left side of the induction moving part 42 is filled with the working fluid part 441, and the second chamber part 92 formed on the right side of the induction moving part 42 is filled with an induction recovery part ( 45) can be placed.

상기와 같은 구조를 갖는 무단변속기의 조립 및 작동을 설명하면 다음과 같다.The assembly and operation of the continuously variable transmission having the above structure will be described as follows.

하우징몸체부(411)에 작동유체부(441)와, 유도이동부(42)와, 유도복원부(45)를 순차로 삽입하고, 하우징몸체부(411)의 개구된 부분은 하우징커버부(412)에 의해 커버한다. 그리고, 하우징몸체부(411)의 외측에 감기는 작동조절부(442)를 장착한다. 이때, 유도회전부(43)는 유도이동부(42)에 결합되고, 하우징커버부(412)를 관통하여 외부로 노출된다.The working fluid portion 441, the inductive movement portion 42, and the inductive restoration portion 45 are sequentially inserted into the housing body portion 411, and the open portion of the housing body portion 411 is inserted into the housing cover portion 412. covered by Then, an operation control unit 442 wrapped around the outside of the housing body 411 is installed. At this time, the inductive rotating part 43 is coupled to the inductive moving part 42 and is exposed to the outside through the housing cover part 412.

상기와 같이 조립 완료된 유도부(40)는 차체에 고정 설치된다. 이때, 유도부(40)와, 입력부(10)와 출력부(20)가 순차로 배치되고, 이들은 전달부(40)에 감겨 연동된다.The guide part 40 assembled as described above is fixedly installed on the vehicle body. At this time, the induction unit 40, the input unit 10, and the output unit 20 are arranged sequentially, and they are wound around the transmission unit 40 and interlocked.

한편, 작동유체부(441)에 전원이 인가되지 않은 상태에서는 차량의 저속 주행이 가능하다(도 2a 참조). Meanwhile, when power is not applied to the working fluid unit 441, the vehicle can be driven at low speed (see Figure 2a).

그리고, 작동유체부(441)에 전원이 인가되어 유도이동부(42)가 이동되면, 유도이동부(42)와 연동되는 유도회전부(43)가 전달부(30)를 이동시킨다. 이로 인해, 전달부(30)는 저속주행시 보다 큰 직경을 갖는 입력부(10)의 회전력을 저속주행시 보다 작은 직경을 갖는 출력부(20)에 전달한다. 이로 인해 고속주행시에느 저속주행시 보다 입력부(10)의 1회전에 따른 출력부(20)의 회전속도가 증가한다(도 2b 참조).Then, when power is applied to the working fluid unit 441 and the inductive movement unit 42 moves, the inductive rotation unit 43 interlocked with the inductive movement unit 42 moves the transmission unit 30. For this reason, the transmission unit 30 transmits the rotational force of the input unit 10, which has a larger diameter when driving at low speed, to the output unit 20, which has a smaller diameter when driving at low speed. As a result, the rotational speed of the output unit 20 increases with one rotation of the input unit 10 during high-speed driving compared to when driving at low speed (see FIG. 2b).

본 발명의 일 실시예에 따른 무단변속기(1)는 유도부(40)에 전원이 인가됨에 따라 전달부(30)의 위치가 변경되어 입력부(10)의 회전력을 출력부(20)로 전달하므로, 최적 변속 타이밍을 제공하여 변속감을 개선하고, 최적 변속비를 실현할 수 있다.In the continuously variable transmission 1 according to an embodiment of the present invention, as power is applied to the induction unit 40, the position of the transmission unit 30 changes and the rotational force of the input unit 10 is transmitted to the output unit 20, By providing optimal shift timing, shift feel can be improved and optimal shift ratio can be realized.

본 발명은 도면에 도시된 실시예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. 따라서, 본 발명의 진정한 기술적 보호범위는 아래의 특허청구범위에 의해서 정하여져야 할 것이다.The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those skilled in the art will recognize that various modifications and other equivalent embodiments are possible therefrom.
