CONTINUOUSLY VARIABLE TRANSMISSION
摘要:
A continuously variable transmission includes: first and second rotating elements that has a common first rotation axis; a planetary ball that is rotatably supported by a support shaft having a second rotation axis separate from the first rotation axis, and is sandwiched between the first rotation member and the second rotating member such that torque transmission is possible between them; grooves, etc., that permit change in a rotation ratio between the first and second rotating members by tilting and rolling the planetary ball; an inclined surface that pushes the support shaft in a direction opposite to the direction of tilt of the support shaft in accordance with spin moment occurring at the planetary ball when moving in an axial direction; and a thrust force transmitting section, such as a movable shaft, etc., by which radial thrust force applied from the planetary ball is transmitted to the inclined surface based on spin moment occurring at the planetary ball.
