<P>PROBLEM TO BE SOLVED: To provide a continuously variable transmission structure with which a V-belt automatic transmission is hardly enlarged, even when a power for moving a movable sheave is made large. <P>SOLUTION: In the continuously variable transmission structure for a V-belt automatic transmission in which a fixed sheave 61 and a movable sheave 62 are provided and a V-belt 53 is hanged around both sheaves, there are provided: a first control mechanism CM1 having a first actuator 90 for moving the movable sheave 62; and a second control mechanism CM2 having a second actuator 100 for moving the movable sheave 62 by working cooperatively with the first control mechanism CM1. Even when the power for moving the movable sheave is set high, the load to each actuator can be reduced and the size increase of each actuator is suppressed and, as a whole, compact sizing of the V-belt automatic transmission can be achieved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
