Abstract
A multiple speed transmission with a plurality of shafts and gears and divided into a number of shift units. Insofar as possible, the respective corresponding shafts and gears among the shift units have substantially the same pitch dimensions. In a multi-speed, single direction transmission, there are two gear and clutch carrying shafts. A clutch in one shift unit joins a gear fixed to the shaft of that shift unit with one or the other of two gears rotatable with respect to the shaft of that shift unit. An additional gear is fixedly mounted on the shaft. The two of such shift units are engaged with different respective ones of their gears being in direct or indirect engagement. For a reversing direction transmission, an intermediate, and therefore direction reversing, gear is interposed between the gears of one interengaged set of gears. In another embodiment, a direction reversing shift unit is connected to one of the two shift units of a single direction transmission. The direction reversing shift unit also comprises a clutch for joining one of two gears with means for driving the main gear of that shift unit in one or the opposite direction.
