Abstract
The powershift transmission comprises nine clutches and eighteen gears, not including the clutches and gears necessary for reverse modes. The powershift transmission provides twenty-four forward modes; a high total transmission ratio of 26.2; and smooth shift steps that are, generally, 15% or less. As such, the transmission utilizes a minimum number of components, while still being extremely functional and versatile.
