Steplessly-adjustable automatic gearbox - has shaft driving main shaft via first differential and torque-converter with clutch

摘要

The gearbox has a gear between input and output shafts and a torque-converter driven from the input shaft. The input shaft (1) drives a first differential (4) via a pair of reduction gears (2,3). The differential is coupled to a first gear shaft (5) driving a main shaft (9) in the same direction via a gear train (6,7,8). The main shaft is coupled to a second gear shaft (14) via the bevel gears of a second differential (11) and a second pair of gears (12,13). A clutch (15) couples the second gear shaft to the torque-converter (19), this being also coupled to the bevel gears of the first differential. ADVANTAGE - Shockless gear changing and improved torque characteristics.
