20110143872 | ELECTRONIC CONTROL V-BELT CONTINUOUSLY VARIABLE TRANSMISSION MECHANISM - An electronic control V-belt continuously variable transmission mechanism is applied in a power transmission system having an engine and support shafts for a driving pulley and a driven pulley, characterized by driving the driving pulley with power supplied by a pulley driving system such that a movable portion of the driving pulley moves axially to the driving-pulley support shaft, thereby enabling a movable portion of a driven pulley connected to the driving pulley to move in response to the axial distance variation, thus changing the rotational speed of the driven pulley. The contact between a cam guide groove of a bearing base of the pulley driving system and a cam guide device is transmitted through rolling friction, and the transmission efficiency is increased by a complex lead angle effect formed between a lead angle of the cam guide groove and a lead screw. | 06-16-2011 |
