ABSTRACT:
An integrated shift motor and electronic controller reduces weight and provides improved performance. The shift control motor includes an output shaft having a first sensor wheel and adjacent sensor which provide signals regarding the rotation and direction of rotation of the motor. The motor drives a gear train having an output member which is coupled to and rotates a shift rail. A sensing wheel is disposed on the output member and adjacent sensors provide signals regarding the angular position of the output member. The sensors drive a microcontroller which in turn drives the shift control motor. Preferably, the sensors, the drive motor, the gear train and the microcontroller are all disposed in a housing. The rotating shift rail includes a pair of spaced-apart followers which engage a cam member which bi-directionally positions a shift fork associated with a multiple position clutch or shift collar.
