ABSTRACT:
A countershaft transmission provides two forward and two reverse speeds using an input shaft, an output shaft, an intermediate shaft, four rotating clutch assemblies, and seven gears. The directional clutch assemblies are mounted in back-to-back relation on the input shaft, the first speed clutch assembly is mounted on the output shaft, and the second speed clutch assembly is mounted on the intermediate shaft. Three of the clutch assemblies are radially aligned, and the output shaft includes a coupling substantially radially aligned with the remaining clutch assembly. A brake mechanism for stopping rotation of the output shaft is provided on the intermediate shaft in substantial radial alignment with the coupling. The transmission is relatively compact axially as well as radially, and is easy to assemble in a housing having two major portions.
