본 발명은 차량용 체인 적용 무단 변속기에 관한 것으로서, 더욱 상세하게는 유성기어 셋트 대신에 체인 기어를 구성하여 전,후진이 용이한 메카니즘을 구현하고자 한 차량용 체인 적용 무단 변속기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuously applied transmission for a vehicle chain, and more particularly, to a continuously applied transmission for a vehicle chain, in which a chain gear is configured instead of a planetary gear set to implement a mechanism for easy forward and backward movement.

일반적인 전,후진 무단 변속기(1)를 제2도에 도시하고 있는데, 본 발명에 따른 무단 변속기를 도시한 도면으로 엔진(2)으로부터 동력을 전달받는 토오크 컨버어터(4)와, 이 토오크 컨버어터(4)의 터어빈측과 직결되는 구동축(6), 그리고 이 구동축(6)에 유성기어 세트(8)를 설치하고 있다.A general forward and reverse continuously variable transmission 1 is shown in FIG. 2, and a torque converter 4 that receives power from an engine 2 and a torque converter in a diagram illustrating a continuously variable transmission according to the present invention. The planetary gear set 8 is provided in the drive shaft 6 which is directly connected to the turbine side of (4), and this drive shaft 6.

상기한 유성기어 세트(8)는 더블 피니언 유성기어 타입이 적용되고 있는데, 이 세트(8)의 유성 캐리어(10)를 구동축(6)과 직결되는 입력요소로 하고, 출력요소인 선기어(12)와, 반력요소인 링기어(16)의 내측에 차차 물림되어 동력을 전달할 수 있도록 구성된다.The planetary gear set 8 has a double pinion planetary gear type applied thereto. The planetary carrier 10 of the set 8 is an input element directly connected to the drive shaft 6, and the sun gear 12 is an output element. And, it is bite inside the ring gear 16 which is a reaction force element is configured to transmit power.

상기한 유성기어 세트(8)의 유성 캐리어(10)가 입력요소일 때 제1 마찰요소(18)의 클러칭이 이루어지면 선기어(12)를 통해 역회전하여 차량을 후진시키게 된다.When the planetary carrier 10 of the planetary gear set 8 is an input element, when the clutching of the first friction element 18 is performed, the vehicle reverses through the sun gear 12 to reverse the vehicle.

그리고 상기한 유성 기어 세트(8)의 유성 캐리어(10)가 입력요소일 때 제2마찰요소(24)의 클러칭이 이루어지면 정회전하여 차량을 전진시킨다.When the planetary carrier 10 of the planetary gear set 8 is an input element, when the second friction element 24 is clutched, the vehicle rotates forward to move the vehicle forward.

상기한 클러치 수단인 제1 마찰수단(18)은 통상의 밴드 브레이크가 사용될 수 있으며, 브레이크 수단인 제2 마찰요소(24)는 통상의 다판식 클러치가 사용될 수 있다.The first friction means 18, which is the clutch means, may use a conventional band brake, and the second friction element 24, which is the brake means, may use a conventional multi-plate clutch.

상기한 선기어(12)로 직결된 구동풀리(22)에 전동이 선택적으로 제1 마찰수단(18)을 통해 이루어지도록 한다.Transmission to the drive pulley 22 directly connected to the sun gear 12 is to be made through the first friction means 18 selectively.

상기한 구동풀리(22)의 전동은 금속 벨트(26)를 통해 종동풀리(28)에 전달되게 하고, 종동축(30)에 설치된 기어 트레인(31)을 거쳐 차동 기어부(32)를 통과하여 출력이 이루어져 변속 작용을 행할 수 있도록 하고 있다.The transmission of the driving pulley 22 is transmitted to the driven pulley 28 through the metal belt 26, and passes through the differential gear portion 32 via the gear train 31 installed on the driven shaft 30. The output is made so that the shifting operation can be performed.

상기한 구동풀리(22) 및 종동풀리(28)는 고정부재(33)와 이동부재(34)로 형성하였다.The driving pulley 22 and the driven pulley 28 were formed of the fixing member 33 and the moving member 34.

이에 따라 감속비를 크게 하고자 할 때에는 구동풀리(22)의 고정부재(33) 및 이동부재(34)와의 사이를 크게 하고, 종동풀리(28)의 고정 및 이동부재(34)와의 사이를 작게 하면 큰 감속비를 얻을 수 있다.Accordingly, in order to increase the reduction ratio, the distance between the fixing member 33 and the moving member 34 of the driving pulley 22 is increased, and the distance between the fixing and the moving member 34 of the driven pulley 28 is reduced. Reduction ratio can be obtained.

그리고 상기와는 반대로 감속비를 작게 하고자 할 때에는 구동풀리(22)의 고정 및 이동부재(34)와 사이를 작게 하고 종동풀리(28)의 고정 및 이동부재(34)와의 사이를 크게 하여 작은 감속비를 얻을 수 있게 되는 것이다.On the contrary, in order to reduce the reduction ratio, the reduction ratio between the fixed and the movable member 34 of the driving pulley 22 is reduced and the ratio between the fixed and the movable member 34 of the driven pulley 28 is increased. You will get it.

그러나 상기와 같은 무단 변속 시스템에 있어서는 풀리의 사이즈에 의하여 그 감속비가 결정됨으로서, 그 감속비를 증대시키는 데에 한계가 있으며, 감속폭이 그다지 크지 못하여 출력이 작은 동력원에 적용할 수 없음은 물론 동력을 효과적으로 사용할 수 없다는 폐단이 있다.However, in the continuously variable transmission system as described above, since the reduction ratio is determined by the size of the pulley, there is a limit to increasing the reduction ratio, and the reduction speed is not so large that it cannot be applied to a power source having a small output, and of course, power is applied. There is a drawback that it cannot be used effectively.

상기한 종래기술은 무단 변속기의 전,후진장치로서, 더블 피니언 유성기어 세트를 적용 설치함에 따라 많은 부품을 필요로 하고, 이에 따른 원가 상승을 초래하는 문제점이 있다.The above-described prior art is a forward and reverse device of a continuously variable transmission, and requires a large number of parts by applying a double pinion planetary gear set, thereby causing a cost increase.

또, 유성기어 세트의 적용으로 많은 부품을 조립하기 때문에 복잡하고 조립시간이 많이 소요되며, 설계의 자유도가 저하되는 단점이 있다.In addition, since many parts are assembled by the application of the planetary gear set, the assembly is complicated and requires a lot of assembly time.

아울러 많은 부품으로 인한 트랜스밋션의 입력축 지지 베어링 설계가 상당히 어려지는 문제점이 있다.In addition, there is a problem that the design of the input shaft support bearing of the transmission due to many components is quite difficult.

상기한 바와 같은 종래 기술의 문제점을 해소하기 위하여 안출된 본 발명의 목적은 유성기어 셋트 대신에 체인 기어를 구성하여 전, 수진이 용이한 메카니즘을 구현하고자 한 내연기관용 스크류 적용 무단 변속기를 제공하는 데 있다.An object of the present invention devised to solve the problems of the prior art as described above is to provide a screw-mounted continuously variable transmission for an internal combustion engine to implement a mechanism that is easy to move and dust by configuring a chain gear instead of a planetary gear set. have.
