| 摘要 |
An electrically controlled actuation apparatus for a rotary clutch is disclosed, which actuates a screw-nut mechanism or an end cam mechanism disposed on a rotation shaft of the rotary clutch so as to control the engagement and disengagement of the clutch and the clutch pressure by using a rotation speed differential transmission which consists of two sets of epicyclic gear unit. The advantages of the actuation apparatus are efficient control and low loss of transmission energy.
