And there was a problem that various restrictions are applied in the planetary gear bearing bearing design.

본 고안은 전술한 종래의 문제점을 해결하기 위해서 안출한 것으로서, 본 고안의 목적은 차량의 후진의 유성기어장치를 적용한 무단변속기의 유성기어에 작용되는 부하를 감소시켜줌으로서 유성기어 및 유성기어 지지베어링의 설계상의 제약을 없애주기 위한 유성기어장치를 적용한 무단변속기용 전후진 기구를 제공해주기 위한 것이다.The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to reduce the load acting on the planetary gear of the continuously variable transmission to apply the planetary gear and planetary gear bearing bearing It is to provide a forward and backward mechanism for a continuously variable transmission using a planetary gear device to remove the design constraints of the gearbox.

전술한 목적을 달성하기 위해서, 본 고안은 유성기어장치를 적용한 무단변속기의 피동축에 축설한 선 기어; 상기 선 기어의 외주에 자전이 자유롭게 맞물려 설치한 유성기어; 상기 유성기어의 외주에 맞물린 상태에서 출력축의 단부에 축설한 링 기어; 상기 링 기어의 둘레에 상기 유성기어를 자전이 자유롭게 지지하는 한편 상기 선 기어의 둘레로 공전시키도록 설치한 캐리어; 및 상기 피동축과 상기 캐리어 사이 및 상기 캐리어와 정지부 사이에 각각 설치한 제 1 클러치와 제 2 클러치로 구성되는 것을 특징으로 하는 유성기어장치를 적용한 무단변속기용 전후진 기구를 제공해 준다.In order to achieve the above object, the present invention is a sun gear arranged on the driven shaft of the continuously variable transmission to which the planetary gear device is applied; Planetary gears, the rotation of which is freely engaged with the outer circumference of the sun gear; A ring gear arranged at an end of the output shaft while being engaged with the outer circumference of the planetary gear; A carrier provided around the ring gear so that the planetary gear freely rotates and revolves around the sun gear; And a first clutch and a second clutch provided between the driven shaft and the carrier and between the carrier and the stop, respectively.

이하에서는 첨부되면을 참조하여 본 고안의 양호한 일실시에를 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

도면은 본 고안에 따른 유성기어장치를 적용한 무단변속기용 전후진기구를 유성기어장치를 적용한 무단변속기에 설치한 상태를 도시하는 개략도이다. 상기 도면에서 점선으로 표시한 부분이 본 고안에 따른 전후진 기구부분이다.Figure is a schematic diagram showing a state in which the forward and backward mechanism for the continuously variable transmission to which the planetary gear device according to the present invention is installed in the continuously variable transmission to which the planetary gear device is applied. The part indicated by the dotted line in the figure is the forward and backward mechanism part according to the present invention.

상기 유성기어장치를 적용한 무단변속기는 전술한 바와같이 이미 공지된 것이다. 참조번호 1은 구동축을 지시하고, 참조번호 2는 피동축을 지시하고, 참조번호 3은 유성기어장치를 지시하며 또한 참조번호 4는 무단변속장치를 지시한다.The continuously variable transmission to which the planetary gear device is applied is already known as described above. Reference numeral 1 designates a drive shaft, reference numeral 2 designates a driven shaft, reference numeral 3 designates a planetary gear device, and reference numeral 4 designates a continuously variable transmission.

상기 유성기어장치를 적용한 무단변속기의 피동축(2)에는 본 고안에 따른 전후진 기구를 장착한다. 참조번호 5는 선 기어를 지시한다. 상기 선 기어(5)는 상기 피동축(2)에 축설한다. 상기 선 기어(5)의 외주에는 유성기어(6)를 자전이 자유롭게 맞물려 설치한다. 한편, 상기 유성기어(6)의 외주에는 출력축(7)의 단부에 축설된 링 기어(8)를 맞물려 설치한다. 한편, 상기 링 기어(8)의 둘레에는 상기 유성기어(6)를 자전 자유롭게 지지하면서 상기 선 기어(5)의 주위로 상기 유성기어(6)를 공전시키는 캐리어(9)를 회전 가능하게 설치한다. 한편 상기 피동축(2)과 상기 캐리어(9)간에는 양자를 서로 물리거나 풀어주는 제 1 클러치(10)를 설치하며 또한 상기 캐리어(9)와 정지부(11)간에는 역시 양자를 서로 물리거나 제 2 클러치(12)를 설치한다.The driven shaft 2 of the continuously variable transmission to which the planetary gear device is applied is equipped with a forward and backward mechanism according to the present invention. Reference numeral 5 designates a sun gear. The sun gear 5 is arranged on the driven shaft 2. On the outer circumference of the sun gear 5, the planetary gear 6 is freely engaged and installed. On the other hand, on the outer circumference of the planetary gear 6 is engaged with the ring gear 8 arranged on the end of the output shaft (7). On the other hand, around the ring gear 8 is rotatably provided with a carrier 9 for revolving the planet gear 6 around the sun gear 5 while supporting the planet gear 6 freely. . On the other hand, between the driven shaft (2) and the carrier (9) is provided with a first clutch (10) to bite or release both of each other, and also between the carrier (9) and the stop (11) also bite or 2 Install the clutch (12).

이하에서는 전술한 구성에 따른 전후진 기구의 작용을 설명하기로 한다.Hereinafter, the operation of the forward and backward mechanism according to the above-described configuration will be described.

상기 제 1 클러치(10)가 작용하게 하는 한편 상기 제 2 클러치가 작용하게 하지 않는 경우, 피동축(2)의 회전에 따라 선 기어(5)와 캐리어(9)가 일체가 되어 회전하게 되고, 이에따라 유성기어(6)가 선 기어(5) 및 캐리어(9)와 일체로 회전하게 되어, 결국 링 기어(8)가 피동축(2)과 일체로 회전하게 되어서 출력축(7)로 상기 피동축(2)과 동일방향으로 회전하게 된다. 이 작용에 의해 차량의 전진이 실현된다.When the first clutch 10 is actuated and the second clutch is not actuated, the sun gear 5 and the carrier 9 are integrally rotated as the driven shaft 2 rotates. Accordingly, the planetary gear 6 rotates integrally with the sun gear 5 and the carrier 9, so that the ring gear 8 rotates integrally with the driven shaft 2, so that the driven shaft becomes the output shaft 7. It rotates in the same direction as (2). By this action, forward movement of the vehicle is realized.

한편, 상기 제 2 클러치(12)가 작용하게 하는 한편 상기 제 1 클러치(10)가 작용하게 하지 않는 경우, 피동축(2)의 회전에 따라 선 기어(5)가 회전하게 되나 캐리어(9)는 정지하게 되고, 이에 따라 유성기어(67)가 자전만하게 되고, 결국 링 기어(8)가 피동축(2)과 반대방향으로 회전하게 되어서 출력축(7)이 상기 피동축(2)과 반대방향으로 회전하게 된다. 이 작용에 의해 차량의 후진이 실현된다.On the other hand, when the second clutch 12 is actuated while the first clutch 10 is not actuated, the sun gear 5 is rotated according to the rotation of the driven shaft 2, but the carrier 9 Is stopped, whereby the planetary gear 67 is rotated only, and the ring gear 8 is rotated in the opposite direction to the driven shaft 2 so that the output shaft 7 is opposite to the driven shaft 2. Will rotate. This action realizes the reverse of the vehicle.

전술한 구성과 작용의 본 고안에 따르면, 유성기어장치를 적용한 무단변속기에 의해 차량의 후진을 실현하는 대신에 전후진 기구를 이용하여 차량의 후진을 실현할 수 있게 되어 유성기어장치를 적용한 무단변속기내의 유성기어 및 유성기어 지지베어링에 미치는 부하를 감소시켜 줄 뿐만 아니라 유성기어 및 유성기어 지지베어링의 설계의 있어서도 제약이 적어진다.According to the present invention of the above-described configuration and operation, instead of realizing the reverse of the vehicle by the continuously variable transmission to which the planetary gear device is applied, it is possible to realize the reverse of the vehicle by using the forward and backward mechanism, so that the planetary gearbox can be implemented. In addition to reducing the load on the planetary and planetary gear bearings, there are fewer constraints in the design of the planetary and planetary gear bearings.
