Abstract

본 발명은 유성기어 셋트 대신에 스크류 기어를 구성하여 전, 후진이 용이한 메카니즘을 구현하고자 한 내연기관용 스크류 적용 무단 변속기로 이를 실현하기 위한 본 발명은 엔진의 동력을 제1 마찰요소의 선택적 결합으로 구동축에 의해 회전하여 출력축에 전달하므로서 후진 동력을 출력하도록 설치된 스크류 기어부재와, 상기한 구동축에 설치된 제2마찰요소의 선택적 결합으로 금속벨트를 통해 구동축에서 종동축에 동력을 전달하도록 설치된 폴리부재와, 상기 폴리부재와 스크류 기어부재에 의해 전달된 동력이 출력되도록 설치된 출력 기어 부재를 포함하여 이루어지고 있다.The present invention provides a screw gearless continuously variable transmission configured to implement a mechanism that facilitates forward and reverse movement by configuring a screw gear instead of a planetary gear set. A screw gear member installed to output reverse power while being rotated by the drive shaft and transmitted to the output shaft, and a poly member installed to transfer power from the drive shaft to the driven shaft through the metal belt by selective coupling of the second friction element installed on the drive shaft; And an output gear member installed to output the power transmitted by the poly member and the screw gear member.

Claims

The screw shaft member is installed to output the reverse power by rotating the power of the engine by the drive shaft by the selective coupling of the first friction element to the output shaft, and the drive shaft through the metal belt by the selective coupling of the second friction element installed on the drive shaft. And a poly member installed to transmit power to the driven shaft, and an output gear member installed to output power transmitted by the poly member and the screw gear member.

2. The screw gear member of claim 1, wherein the screw gear member includes a first rotating body formed on the upper portion of the drive shaft by forming a first gear to rotate forward in one direction when clutching by the first friction element, and from the first rotating body to the rotating shaft. Screwless continuously variable transmission for an internal combustion engine comprising a second rotating body which is connected to form a second gear unit so as to interlock with the forward rotation, and installed to rotate the output shaft of the output gear member at an upper portion thereof.
