Parallel shaft transmission

Abstract

A compact transmission comprises a first input shaft 1, a second input shaft 2 and a counter shaft 3, which are disposed parallel with one anther. This transmission further comprises at least a set of first speed ratio gear train 25a, 25b, 24a, 24b, 26a, 26b and 26c, which are disposed between the first input shaft 1 and the counter shaft 3, at least one first clutching means 15 and 14 which connects and disconnects a first speed ratio drive gear rotationally to and from the first input shaft, respectively, at least a set of second speed ratio gear train 22a, 22b, 21a, 21b, 23a and 23b, which are disposed between the second input shaft 2 and the counter shaft 3, at least one second clutching means 12, 11 and 13 which connects and disconnects a second speed ratio drive gear to and from the second input shaft, respectively, and a connection gear train 30 which is used for power transmission from the first input shaft to the second input shaft through gears 32 and 33 on an idle shaft that is disposed parallel with the first input shaft.
