도1에 있어, 입력축의 요소(1)과 요소(2)의 라인은 엔진의 동력이 유성기어셋트에 직접 전달되는 라인이고, 요소(3).(4).(5)는 속도가 변화되어 전달 되는 라인으로 두개의 동력 전달 경로를 구성하며, 이 두개의 라인은 유성기어셋트에 요소(2)와 요소(5)로 입력 연결되어 있고, 유성기어 셋트의 요소(6)에 의하여, 다시 한개의 라인으로 합쳐저 출력축(7)에 최종 출력되는 구조로, 한 라인의 동력을 두 라인으로 나누고, 나누어진 두라인을 다시 한개의 라인으로 출력하는 형태이다.In Fig. 1, the lines of elements 1 and 2 of the input shaft are lines in which the engine power is transmitted directly to the planetary gear set, and elements 3, 4 and 5 are changed in speed. The transmission line constitutes two power transmission paths, and these two lines are connected to the planetary gear set as elements 2 and 5, again by the element 6 of the planetary gear set. It is a structure that is finally output to the output shaft 7 by combining the lines of. The power of one line is divided into two lines, and the divided two lines are output again as one line.
연결 형태에 있어 도2의 무단변속기는, 입력축과 직결된 일정 회전비로 변화가 없는 라인의 구성으로, 입력축(1)과 선기어(2-14)의 구성되어 있고, 입력과 출력의 회전비가 변화하는 라인의 구성으로, 구동풀리(3-11).피동풀리(4-12).피동축(8).기어(16).회전방향 전환용 기어(17).캐리어구동기어(18).캐리어축 피니언기어(5-13) 순으로 연결되어 있으며, 출력과정으로, 링기어(6-15)를 사용한 형태인 것과,In the connection form, the continuously variable transmission shown in FIG. 2 is a line structure which does not change at a constant rotational ratio directly connected to the input shaft, and is composed of the input shaft 1 and the sun gear 2-14, and the rotation ratio of the input and output changes. In the configuration of the line, the drive pulley (3-11), the driven pulley (4-12), the driven shaft (8), the gear (16), the gear for turning the rotation direction (17), the carrier driving gear (18), the carrier shaft Connected to the pinion gear (5-13) in order, the output process, the form using the ring gear (6-15),
도3의 무단변속기와 같이, 입력축과 직결된 일정 회전비로 변화가 없는 라인의 구성으로 입력축(1).입력축기어(16).회전방향 전환용기어(17).기어(18). 링기어(2-15)순의 연결 되어있고, 입력과 출력의 회전비가 변화하는 라인의 구성으로 구동풀리 (3-11).피동 풀리 (4-12).피동축(8).캐리어를 통한 피니언기어(5-13)순으로 연결 구성 되었으며, 출력과정으로 선기어(6-14)를 사용한 형태인 것의 두가지의 연결구성이 있으며, 이와 같은 구성 모두는, 입력축(1)대신 피동축(8)을 입력축으로 바꾸어도 사용하여도 무단변속 형태의 구성이 된다.As in the continuously variable transmission of Fig. 3, the input shaft 1, the input shaft gear 16, the rotation direction switching gear 17, and the gear 18 in the configuration of a line with no change at a constant rotational ratio directly connected to the input shaft. Drive pulleys (3-11), driven pulleys (4-12), driven shafts (8). The gears are connected in order of pinion gear (5-13), and there are two types of connections in the form of using sun gear (6-14) as the output process. All of these configurations are driven shafts (8) instead of input shafts (1). Even if is used as an input shaft, it becomes a continuously variable configuration.
도5에 있어, 무단변속기는 유성기어셋트 연결구성의 대용으로 차동기어장치(23)를 적용 구성한것.5, the continuously variable transmission employs a differential gear device 23 as a substitute for the planetary gear set connection configuration.
작동의 원리로서,도2의 예로 설명을하자면, 요소(3)의 구동풀리(3-11)과 요소(4)의 피동풀리(4-12)에서 변속된 회전이, 최저속의 상태가 되면 요소(5)의 캐리어축 피니언기어(5-13)의 회전이 요소(2)의 선기어(2-14)의 회전보다 뒤떨어져 요소(6)의 링기어(6-15)는 역회전 하여 후진 형태가 되고 요소(3)과(4)의 변속 과정에서 증속이 진행되어 요소(5)의 피니언기어(5-13)의 속도가 점진적인 증가가 되면 요소(6)의 링기어(6-15)의 회전도 증가 하게 되며, 요소(5)의 (5-13)의 회전이 요소(2)의 (2-14)의 회전에 점진적으로 가까워져 최종적으로 같거나 요소(2)의 (2-14)회전을 상회하면 요소(6)의 (6-15)회전이 최고속 형태가 된다.As an example of the operation, in the example shown in Fig. 2, when the rotation shifted in the driving pulley 3-11 of the element 3 and the driven pulley 4-12 of the element 4 becomes the lowest speed state, The rotation of the carrier shaft pinion gear (5-13) of (5) is inferior to the rotation of the sun gear (2-14) of the element (2), so that the ring gear (6-15) of the element (6) is reversely rotated to Rotation of the ring gear 6-15 of the element 6 when the speed of the pinion gear 5-13 of the element 5 increases gradually in the process of shifting the elements 3 and 4. Also, the rotation of (5-13) of the element (5) is gradually closer to the rotation of (2-14) of the element (2) and finally the same or (2-14) rotation of the element (2). Above it, the (6-15) rotation of the element 6 is at its highest speed.
따라서 요소(3)의 구동풀리(3-11)과 요소(4)의 피동풀리(4-12)의 변속 범위 안에서 최저 변속점인 후진과 최고 변속점인 최고속 까지의, 중립을 포함한 전과정이 무단 변속이 된다.Therefore, in the shifting range of the driving pulley (3-11) of the element (3) and the driven pulley (4-12) of the element (4), the whole process including neutral, up to the lowest shift point and the highest shift point, the highest speed. It becomes stepless speed change.
그리고 요소(3)과(4)의 부분은, 여러 형태의 무단변속기(벨트식 무단변속기.트로이달 무단변속기.기타 무단변속기) 주 변속부를 적용할 수 있는 부분으로서, 벨트식 무단변속기의 주변속부를 본 발명의 적용 예로 도2와 도3과 같이 구동풀리(3-11)를 요소(3)의 부분으로 피동풀리(4-12)를 요소(4)의 부분으로 적용 구성 하였고,In addition, the parts of the elements 3 and 4 are various types of continuously variable transmissions (belt continuously variable transmissions, troidal continuously variable transmissions, and other continuously variable transmissions). 2 and 3, the driving pulley 3-11 is configured as a part of the element 3, and the driven pulley 4-12 is configured as a part of the element 4, as shown in FIGS.
트로이달 무단변속기의 적용 예로서 도7과 같이 구동디스크(3-21)은 요소(3)의 부분으로 피동디스크(4-22)는 요소(3)의 부분으로 적용 할수 있으며,As an example of the application of the trodley continuously variable transmission, as shown in FIG. 7, the driving disk 3-21 may be applied as a part of the element 3, and the driven disk 4-22 may be applied as a part of the element 3.
이상의 예와 같이 현제의 발명된 기타 다른 형태의 무단 변속기의 주변속부도 본 발명의 구성 요소(2)와 요소(3)의 부분에 적용할 수 있다는 것을 알수 있다.As described above, it can be seen that the peripheral speed of the present invention and other types of continuously variable transmissions can also be applied to the components 2 and 3 of the present invention.
벨트식 무단변속기 주변속부를 본발명에 적용한 구성중 동력전달 효과 증대및 내구성 향상을 목적으로, 도6과같이 구동풀리(3-23)와 피동풀리(4-24)를 추가하여 주변속부를 구성하였고, 필요에 따라 그 이상의 갯수로 구성할 수 도 있으며, 본구성을 적용하지 않은 일반적 벨트식 무단변속기에 적용할 수 있다.In order to increase the power transmission effect and improve the durability of the belt-type continuously variable transmission as part of the present invention, as shown in Fig. 6, the drive pulley (3-23) and the driven pulley (4-24) are added to form the peripheral speed portion. If necessary, it can be configured with a larger number, and can be applied to a general belt type continuously variable transmission without applying this configuration.
도4의 무단변속기의 풀리(19)와 풀리(20)의 연결은 벨트나 체인을 사용할 수 있으며,체인사용시 19)와 (20)을 스프로킷으로 대채 할수있다.Connection of the pulley 19 and the pulley 20 of the continuously variable transmission of FIG. 4 may use a belt or a chain, and when the chain is used, 19) and 20 may be replaced by a sprocket.
본 발명의 기본구성에 기존의 모든 무단변속기(벨트식.트로이달식.기타 방식)의 주변속부를 적용 접목시켜 후진에서 부터 중립. 전진. 최고속 까지의 전과정을 무단변속이 가능하도록 하는 변환 기능을 하는 효과, 전후진 선택 부분의 클러치 브레이크가 없어 간단한 구조로 생산원가 절감 효과, 미세한 감속부터 광범위한 변속폭으로 연비향상 효과, 차량 스타트 시의 용이성 등의 효과가 있다By applying the peripheral parts of all existing continuously variable transmission (belt type, troidal type, etc.) to the basic configuration of the present invention by applying the neutral from the reverse. Advance.
