Abstract: The present invention discloses a three-gear automatic transmission for electric vehicle with a brushless control-by-wire centrifugal ball arm engagement device. One brushless control-by-wire centrifugal ball arm engagement device is provided between each gear input gear and each gear driving gear; and by controlling the engagement and disengagement of the brushless control-by-wire centrifugal ball arm engagement device, the shift control of the three-gear automatic transmission for electric vehicle with a brushless control-by-wire centrifugal ball arm engagement device is performed. The present invention has such advantages as compact structure, being capable of dynamic gear-shift, no mechanical or hydraulic gear-shift components and low operational energy consumption.

Abstract: The present invention discloses an electromagnetic clutch of a brushless control-by-wire centrifugal ball arm engagement device, which comprises a brushless electromagnet, a thrust pressing disc, a driven inner-spline hub, a control-by-wire drive disc, a centrifugal ball arm hollow disc, centrifugal ball arm pins, centrifugal ball arms, centrifugal balls, a magnetic conductive force transmitting disk, a drive shaft; once the brushless electromagnet is energized, the centrifugal ball arms and the centrifugal balls each make a circular motion around the centrifugal ball arm pin outwardly along the smooth surface of the thrust pressing disc by the action of centrifugal force produced by them when rotating with high speed. The component of the centrifugal force in the direction of the central axis of the centrifugal ball arm hollow disc drives the thrust pressing disc to compress the outer-spline-groove steel sheets and the inner-spline-groove friction discs with each other, which makes the clutch engaged. The clutch is engaged smoothly with no impact, which is suitable for high-speed rotation and transmitting large torque.
