ABSTRACT:
A torsional vibration elastomeric damper coupling arrangement for a manual transmission countershaft. The coupling includes a first driven gear journalled on the countershaft and in constant mesh with the input shaft gear. A second driven gear is fixed on the countershaft and is in constant mesh with a speed gear journalled on the main shaft. The first and second driven gears each have a set of longitudinally extending axial teeth interposed to define predetermined clearances therebetween. An elastomeric damper sleeve surrounds the interposed teeth to isolate the driven gears. The elastomeric material inhibits the transfer of torsional vibration from the input shaft to the countershaft. Thus, the coupling isolates all the drive shaft speed gears, in mesh with the countershaft drive gears, from any input shaft torsional vibration.
