ABSTRACT:
A compound transmission (110) of lighter weight and/or shorter axial length as compared to comparable prior art transmissions is provided. The compound transmission of the present invention utilizes main transmission section countershafts (124) and auxiliary transmission section countershafts (162) which are coaxial and am supposed for independent rotation within a common transmission housing (116) solely by means of bearings (126, 162D) carried by the forward transmission end wall (116A) and the rearward transmission end wall (116B). The transmission mainshaft (146) is supposed for rotation within the transmission housing solely by the input shaft (118) and/or the output shaft (158). One of the countershafts (162) and/or the mainshaft (146) may be of a tubular structure and telescopically surrounds the other of the countershafts (124) and one of the input and/or output shafts, respectively.
