Abstract
A multiple input and preferably multiple output transmission for industrial, commercial and other vehicles includes axially aligned input and output shafts, a single aligned countershaft, first, second and third input gears, a plurality of foward output gears with one of the forward output gears also being capable of serving as one of the input gears. First, second and third driven countershaft gears are in constant mesh with respective ones of the input gears, and each one of a plurality of driving countershaft gears is in constant mesh with a separate one of the forward output gears, with one of the driving countershaft gears also being capable of serving as one of the driven countershaft gears. Multiple clutch means are utilized for selectively drivably connecting the countershaft with one of the input gears and for selectively drivably connecting the output shaft with the countershaft. A reverse-idler shaft together with its associated gearing provides for a plurality of reverse speeds.
