Integrated shift motor and electronic controller

摘要

An integrated shift motor (114) and electronic controller reduces weight and provides improved performance. The shift control motor (114) includes an output shaft (116) having a first sensor wheel (120) and adjacent sensor (122) which provide signals regarding the rotation and direction of rotation of the motor. The motor drives a gear train having an output member (150) which is coupled to and rotates a shift rail (180). A sensing wheel (144) is disposed on the output member and adjacent sensors (160) 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 (180) includes a pair of spaced-apart followers (194) which engage a cam member (206) which bi-directionally positions a shift fork (200) associated with a multiple position clutch or shift collar.
