Title:
CONTINUOUSLY VARIABLE TRANSMISSION APPARATUS USING TORQUE CONVERTER
Document Type and Number:
WIPO Patent Application WO/2014/051270
Kind Code:
A1
Abstract:
Disclosed is a continuously variable transmission apparatus comprising: a housing; an input shaft which is rotatably supported by the housing; a first planetary gear assembly comprising a first sun gear, a plurality of first planetary gears, a first carrier, and a first ring gear; a torque converter comprising a turbine, an impeller, and a lock-up clutch, wherein the turbine is fixed to the first ring gear of the first planetary gear assembly; a second planetary gear assembly comprising a second sun gear, a plurality of second planetary gears, a second carrier, and a second ring gear, wherein the second sun gear is fixed to the input shaft and the second carrier is fixed to the turbine in the torque converter; an output shaft which is rotatably supported by the housing and is fixed at the center of rotation of the second ring gear in the second planetary gear assembly; and a forward/reverse unidirectional rotation tool for converting and restricting the rotation direction of the carrier so as to rotate only in a clockwise direction or a counter-clockwise direction. According to the present invention, power loss is prevented by allowing output immediately when moving, and automatic transmission depending on a driving state can be enabled at a high rpm.
