ABSTRACT:
A power synchronizer assembly (10) for selectively increasing the rotational speed of a mechanical change gear transmission (12) input shaft (22), main section countershaft (58) and ratio gears (82, 84, 86, and 88) independently of the rotational speed of the drive engine (14) is provided. The power synchronizer assembly includes a sun gear shaft (174) drivingly associated with the main section countershaft and carrying a sun gear (176) fixed thereto which is in constant engagement with the planet gears (180) of a planet gear carrier (178) rotatably driven by the transmission output shaft (28). A ring gear (182) surrounds and is in constant engagement with the planet gears and is selectively frictionally coupled for rotation with the transmission housing (68) by means of a band brake and band brake operating mechanism (186 and 188).
