ABSTRACT:
A transmission is provided having a housing, a power input shaft rotatably mounted at one end, a power output shaft rotatably mounted at the other end coaxially with the power input shaft, a splined clutch member affixed to the end of one of the shafts having a gear engaged over a portion thereof, a second splined clutch member freely rotatably mounted on the other shaft and having a gear engageably mounted over a portion thereof, the end of each clutch-engaging member extending beyond each gear, a splined countershaft rotatably supported in the housing and having a gear engaged at each end engaging the gears mounted on the power input and output shafts, a third splined clutch member affixed to one of the shafts and positioned intermediate the first and second splined clutch members and of the same diameter as said clutch members, a clutch sliding ring or coupling member mounted over the cylindrical clutch member having a splined bore engaging the third clutch member and axially slidable with respect thereto and adapted to engage alternatively the first or said second clutch members and to couple them to the third clutch member and a groove provided in the clutch sliding ring engaging a fork-operating member for sliding the clutch sliding ring alternatively in engagement with the first clutch member or the second clutch member, thereby providing either direct drive or ratioed drive between the power input shaft and the power output shaft. In a preferred form of the invention the gears are all mounted on splined shafts of the same diameter and configuration to make them capable of being rearranged to provide different gear ratios.
