도 1은 본 발명의 하우징과 이동수단을 제거하여 나타낸 사시도,1 is a perspective view showing the housing and the removal means of the present invention;

도 2는 본 발명을 나타낸 사시도.Figure 2 is a perspective view of the present invention.

본 발명은 무단변속기에 관한 것으로써, 상세하게는 트랙션 구동방식의 새로운 무단변속기에 관한 것이다.   The present invention relates to a continuously variable transmission, and more particularly, to a new continuously variable transmission of a traction drive type.

무단변속기는 기본적으로 유단변속기와는 달리, 최고 변속비와 최저 변속비 사이를 연속적으로 변속시킴으로써, 엔진의 동력을 최대한 이용하여 우수한 동력성능과 연비향상을 얻을 수 있도록 운전 가능한 변속기이다.  The continuously variable transmission, unlike the stepped transmission, is a transmission that can be operated to obtain excellent power performance and fuel efficiency improvement by making the most of the engine power by continuously shifting between the highest speed ratio and the lowest speed ratio.

특히, 본 발명과 관계가 깊은 트랙션 구동방식의 무단변속기는, 높은 전단응력을 가진 윤활류를 통하여 금속의 롤러의 회전을 이용한 동력전달방식을 가진 변속기인데, 현재 이 트랙션 무단변속기는 크게 토로이달(Full Toroidal)형식과 반토로이달(Half Toroidal)형식으로 나눠져 있다. 토로이달 형식은 인풋토로이달디스크와 아웃풋토로이달디스크에 하중을 작용시키고, 그 두 디스크 사이에 있는 롤러가 회전함과 동시에 디스크와의 접촉유효반경을 변화 시킴에 따라 변속이 되는 형식이다. 반토로이달 형식은 원추모양으로 생긴 롤러와, 그 롤러와 스핀양이 0 이 되도록 인풋토로이드와 아웃풋토로이드의 접촉표면을 정렬시키고, 롤러와 그 두 토로이드의 접촙유효반경을 제어해 변속하는 방식이다.   In particular, the continuously variable traction drive system is a transmission having a power transmission method using rotation of a metal roller through lubricating oil having a high shear stress, and the traction continuously variable transmission is largely toroidal (Full). It is divided into Toroidal form and Half Toroidal form. The toroidal type is a type in which a load is applied to an input toroidal disc and an output toroidal disc, and the gear is shifted as the roller between the two discs rotates and the effective radius of contact with the disc changes. The semi-toroidal type aligns the cone-shaped roller, the contact surface of the input toroid and the output toroid such that the roller and the spin amount are zero, and controls the variable effective radius of the roller and the two toroids to shift. That's the way.

하지만, 상기 토로이달 형식과 반토로이달 형식의 트랙션 무단변속기는 롤러의 정밀한 제어가 어렵고, 접촉구동부의 높은 압력과 접촉구동부의 면적이 점에 가까운 작은 면적이기 때문에 많은 피로가 쌓인다.  However, the toroidal type and the anti-toroidal type traction CVs are difficult to precisely control the rollers, and the high pressure of the contact driver and the area of the contact driver are small, and thus a lot of fatigue is accumulated.

따라서 본 발명의 목적은 제어가 쉽고, 접촉구동부의 피로가 적은 트랙션 무단변속기를 제공함에 있다.   Accordingly, an object of the present invention is to provide a traction continuously variable transmission that is easy to control and has low fatigue in contact driving units.

이와 같은 본 발명의 목적은 원추형구동토로이드와 원추형피동토로이드의 회전축이 서로 평행하고 엇갈리게 배치하고, 그 두 원추형토로이드 사이에 원추형구동토로이드로부터 넓은 접촉면적으로 동력을 전달받는 원추형구동측롤러와, 그 원추형구동측롤러로부터 동력을 전달받아 넓은 접촉면적으로 원추형피동토로이드에 동력을 전해주는 원추형피동측롤러와, 상기 원추형구동측롤러의 동력을 원추형피동측롤러로 동력을 전해주는 기어식전달수단과, 상기 원추형구동측롤러와 원추형피동측롤러와 기어식전달수단을 고정시켜주는 하우징과, 그 하우징을 이동시켜 변속을 하는 이동수단으로 이루어진 무단변속기로 이루어진다.   The object of the present invention is a conical driving roller and the rotating shaft of the conical driving toroid is arranged parallel and staggered with each other, and the power is transmitted between the two conical toroids from the conical driving toroid with a wide contact area. And a conical driven roller that receives power from the conical driven roller and transmits power to the conical driven toroid with a large contact area, and a gear type that transmits the power of the conical driven roller to the conical driven roller. And a continuously variable transmission comprising a transmission means, a housing for fixing the conical driving side roller, a conical driven side roller, and a gear transmission means, and a moving means for shifting the housing.
