Title:
CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP2014211180
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To transfer torque of driving wheels promptly to a driving source for running in a continuously variable transmission including an output speed reducer having a second one-way clutch.SOLUTION: A continuously variable transmission includes: an input part to which a driving force from a driving source for running is transferred; an output shaft; a lever crank mechanism; a first one-way clutch; an output speed reducer that decelerates a rotational speed of the output shaft using a rotational load of the driving source for running; and a controller. The output speed reducer includes a second one-way clutch that idles an oscillation link when the link relatively rotates toward one side respective to the output shaft and secures the oscillation link to the output shaft when the link relatively rotates toward the other side. When operating the output speed reducer, the controller prevents an oscillation speed of the oscillation link from being the rotational speed of the output shaft or more and increases a radius of rotation of an adjustment mechanism for radius of rotation if a rotational speed of the input part exceeds a value of the rotational speed of the output shaft multiplied by a change gear ratio of the output speed reducer.
