ABSTRACT:
By making the ratios of the gear pairs in a conventional single countershaft transmissions a particularly defined sequence, and mounting the gear elements that are not affixed to the countershaft so that, that of the first gear pair is free to rotate on and couplable to the input shaft, that of the second gear pair is free to rotate on the output shaft and couplable to both the input and output shafts, with those of the remaining pairs free to rotate on and couplable to the output shaft, the number of ratios in the transmission will be enhanced by a factor of two (2) and the continuum will be in a particular geometric progression. By extending the particularly defined ratio sequence to a series arrangement of similarly constructed gearboxes, the number of continuum ratios in the resulting transmission will be enhanced by a factor of three (3) to five (5) and the continuum will again be of the same geometric progression.
