본 발명은 무단변속기에 관한 것으로, 특히 토오크 컨버터와 유성기어를 사용하여 입력축의 회전 속도와 공급 동력, 출력축에 부관된 부하 그리고 토오크 컨버터의 특성에 따라 변속비가 연속적이고 자동적으로 변하도록 고안된 무단변속기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuously variable transmission, in particular, using a torque converter and a planetary gear in a continuously variable transmission in which the speed ratio is continuously and automatically changed according to the rotational speed and supply power of the input shaft, the load attached to the output shaft, and the characteristics of the torque converter. It is about.
일반적으로 변속기는 하나의 동력을 여러 부하 상태에 대응시키면서 출력으로부터 여러가지 다른 값의 속도를 얻기 위한 목적으로 사용되는 바, 대부분의 경우 변속기가 낼 수 있는 변속비가 수가 많을수록, 최대 변속비를 최소 변속비로 나눈 값이 클수록 바람직하다.In general, transmissions are used for the purpose of obtaining a different speed value from the output while corresponding one power to various load conditions. In most cases, the more transmission ratios that a transmission can produce, the maximum transmission ratio divided by the minimum transmission ratio. The larger the value, the better.
그 예로 통상적으로 널리 사용되고 있는 차량용 수동변속기와 자동변속기의 단수가 점차 증가하는 추세를 들 수 있다.For example, the number of stages of a vehicle manual transmission and an automatic transmission that are generally widely used is gradually increasing.
그리고 통상의 변속기에 있어서 변속비의 수가 증가하게 되면 변속기의 구조가 복잡해질 뿐만 아니라 자동변속기의 경우 제어수단이 복잡해지고, 수동변속기의 경우 조작이 어려워진다.In addition, when the number of transmission ratios increases in a conventional transmission, not only the structure of the transmission is complicated, but also the control means of the automatic transmission becomes complicated, and the manual transmission becomes difficult to operate.
먼저, 제1도를 참조하여 종래의 기술에 대하여 설명한다.First, the prior art will be described with reference to FIG.
그리고 이미 알려진 국내특허 공개 92-7852호가 있으나 이는 출력축의 토크변화를 안정시켜, 필링이 양호한 변속을 실시할 수 있는 차량용 자동 변속기의 변속제어방법을 제공하는 것이지만 본 발명은 공급동력, 입력축의 회전속도, 출력축에 부과된 부하 등에 따라 스스로 변속비를 선택하여 동력을 전달하는 것이다. 즉, 상기 선행발명은 단지 출력축의 토크변화를 안정시켜 필링이 양호한 변속을 하는 것으로 본원 발명과는 기본적으로 그 목적, 구성 및 작용효과가 판이한 것이다.Although there is already known Korean Patent Publication No. 92-7852, this provides a shift control method for an automatic transmission for a vehicle which can stabilize the torque change of the output shaft and perform a shift with good filling, but the present invention provides a supply power and a rotation speed of the input shaft. In other words, it transmits power by selecting the gear ratio by itself according to the load imposed on the output shaft. That is, the foregoing invention merely stabilizes the torque change of the output shaft to achieve a good speed change, and basically the object, construction and effect of the present invention are different.
본 발명은 주어진 변속비 구간내에서 연속적으로 무한히 많은 변속비중 공급동력, 입력축의 회전속도, 출력축에 부가된 부하 등에 따라 스스로 변속비를 선택하여 동력을 전달함으로써 조작이 간편하고 통상의 변속기에 비하여 구조가 간단하여 소형의 무단변속기를 제공하는 것이다.The present invention is simple in operation and simple in structure compared to a normal transmission by transmitting the power by selecting the transmission ratio by itself according to infinitely large number of transmission ratio supply power, rotation speed of the input shaft, load applied to the output shaft, etc. within a given transmission ratio section. To provide a small continuously variable transmission.
종래의 토오크컨버터와 유성기어를 이용한 무단변속기는 제1도에 도시되어 있는 바와 같이 임펠러(4)와 터어빈(5)과 직결클러치(17)의 3요소를 가지는 일반적인 직결클러치부 유체식토오크컨버터 및 보조변속장치로서 선기어(12)와 선기어(12)의 동축에 연결된 링기어(14)와 선기어(12)와 링기어(14)의 사이에 감합된 피니언 기어(13)를 회전가능하게 지지된 케리어(15) 등으로 구성되어 있다.The continuously variable transmission using a conventional torque converter and a planetary gear has a general direct clutch part fluid torque converter having three elements, an impeller 4, a turbine 5, and a direct clutch 17, as shown in FIG. Carrier rotatably supported the ring gear 14 coupled to the coaxial of the sun gear 12 and the sun gear 12 and the pinion gear 13 fitted between the sun gear 12 and the ring gear 14 as an auxiliary transmission. (15) and the like.
이러한 종래 기술은 터어빈(5)에서 발생한 동력을 터어빈축(6)을 통하여 링기어(14), 선기어(12), 케리어(15) 등으로 변속비를 얻기 힘들다는 문제점이 있는 것이다.The prior art has a problem that it is difficult to obtain a transmission ratio from the power generated in the turbine 5 to the ring gear 14, the sun gear 12, the carrier 15, and the like through the turbine shaft 6.
따라서 본 발명의 목적은 주어진 변속비 구간내에서 연속적으로, 무한히 많은 변속비중 공급동력, 입력축의 회전 속도, 출력축에 부과된 부하 등에 따라 스스로 변속비를 선택하여 동력을 전달하므로써 조작이 편리하고 통상의 변속기에 비하여 상대적으로 구조가 간단하고 크기가 작고 저렴한 생사비로 제작할 수 있는 새로운 구조의 무단변속기를 제공하려는 것이다.Accordingly, an object of the present invention is to continuously operate within a given transmission ratio section, and to transmit power by selecting a transmission ratio according to the infinitely large number of transmission ratio supply power, the rotational speed of the input shaft, and the load imposed on the output shaft. In comparison, the company intends to provide a continuously variable transmission with a new structure that is relatively simple in structure, small in size, and low in cost.
