Title:
CONTINUOUSLY VARIABLE TRANSMISSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2015/060633
Kind Code:
A1
Abstract:
The present invention relates to a continuously variable transmission apparatus. The present invention provides a continuously variable transmission apparatus comprising: a housing rotatably installed on a side of a vehicle body; a central shaft passing through the center of the housing and having opposite end portions fixedly attached to a side of the vehicle body; a support part installed on the outer surface of the central shaft to move forward and rearward in the axial direction of the central shaft; a transmission means having one side connected to one side of the support part and providing a forward and rearward moving force to the support part; an input shaft rotatably installed on the outside of the support part and having one side connected to an external power means; a power transfer assembly rotatably installed on the outside of the input shaft and co-rotating when the input shaft rotates; at least one conical gear part rotatably installed on a side of the power transfer assembly and having an inclined surface formed on the outer surface thereof and one side engaged with one side of the support part, wherein the inclined surface has a smaller diameter toward the center thereof; and an output part fixedly attached to one side of the inner surface of the housing and brought into contact with the inclined surface to transmit the rotating force of the conical gear part to the housing. According to the present invention as described above, while one side of the output part is brought into contact with one side of the inclined surface of the conical gear part, the conical gear part is moved forward and rearward in the axial direction of the central shaft to achieve continuously variable transmission, and an input rotating speed is reduced at a predetermined rate through revolution and rotation of the conical gear part at the same time. Thus, effects are provided such as life-time can be significantly enhanced by achieving simple configurations and minimum interference therebetween and speed change can be easily made through continuously variable transmission to correspond to a predetermined input rotating speed.
