Three-gear automatic transmission for electric vehicle with a brushless control-by-wire centrifugal ball arm engagement device
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.
