ABSTRACT:
A shiftable planetary gear train is driven by the output of a conventional vehicle transmission which engages a ring gear of the planetary gear train. The planetary gear train includes two shifting sleeves which are axially displaced as a unit. One of the sleeves is rotatably driven by the ring gear while the other sleeve is nonrotatable. In one shift position, the rotatable sleeve is brought into driving engagement with a planet carrier which drives an output shaft thereby fixing the output shaft relative to the ring gear. When the shifting sleeves are unitarily moved to a neutral position, the rotatable sleeve is disengaged from the planet carrier. Further displacement of the shifting sleeves results in locking the sun gear against rotation. This is accomplished by engagement between the nonrotatable sleeve and a spur gear which is fixed to an extension of the sun gear. Movement of the shifting sleeves is controlled through a fluid cylinder which is coupled to a shift fork, one arm of which engages a groove in one of the sleeves and the other arm of which engages a groove in the other sleeve. Detents are provided to seat the sleeves in the various shifting positions.
