ABSTRACT:
The constant-mesh transmission includes a gear case, an input shaft, a counter shaft and an output shaft. An input drive gear integral with the input shaft meshes with the counter shaft drive gear. First, second and third speed counter shaft gears are integral with the counter shaft. A fifth speed counter shaft gear and a counter shaft sprocket are journaled on the counter shaft. First, second and third speed driven gears are journaled on the output shaft and in mesh with the first, second and third speed counter shaft gears. A reverse driven sprocket is journaled on the output shaft. A fifth speed output shaft gear is secured to the output shaft. A chain is trained around the sprockets. Clutch assemblies are mounted on the output shaft and a clutch is mounted on the counter shaft. A clutch locks gears to the output shaft for first and second speed. A clutch locks a gear to the output shaft for third speed or locks the input shaft to the output shaft for fourth speed. A clutch locks a gear to the counter shaft for fifth gear or locks a drive sprocket to the counter shaft. A clutch locks a driven sprocket to the output shaft. A shift fork simultaneously locks a sprocket to the counter shaft and locks a sprocket to the output shaft to drive the output shaft in a reverse direction from the input shaft rotation. Some of the clutches include synchronizers.
