ABSTRACT:
Tracked vehicles are steered by the differential speed between the two tracks. This transmission has two output drive shafts which can be driven at different speeds for controlling such a tracked vehicle. Identical drive trains are provided between an input shaft and each of the two output shafts. The drive trains each include transfer gears mounted on a pivotable spider. A second input rotates the spider. One input shaft is used for driving the two output shafts. Rotation of the other input shaft adds to the rotational speed of one output shaft and subtracts from the rotational speed of the other output shaft. By using identical drive trains and transfer gears on a spider in each of the drive trains, the transmission is balanced so that substantially the same torque is required for changing the speed of both drive trains.
