Vehicle transmission having countershaft and planetary portions
This patent describes a vehicle transmission comprising: a countershaft transmission including an input first shaft, a second shaft, an output third shaft, gears operatively associated with the shafts, a reversing idler gear cooperatively engaging two of the gears, and low, high, and reverse clutch assembly means for selectively connecting the gears in a preselected manner. The reverse clutch assembly provides either one of two forward speeds and one reverse speed at the third shaft, the low and high clutch assembly means being disposed generally along the second shaft; and a planetary transmission serially driven by the third shaft and including interconnected planetary gear sets and brake assembly means for selectively actuating one of the planetary gear sets and providing one speed for use with each speed of the countershaft transmission.
