(14) Bevel gear Power from the drive shaft turns bevel pinion (13) in the front axle. The power enters the axle through the bevel pinion. The bevel pinion turns the bevel gear (14) which is fastened to the differential case.Power is transferred through the differential by pinions (12) and side gears (11) to splined shaft (10). The shaft is joined by a splined coupler (9) to shaft (6) in the final drives. The main components of the final drives are carrier (8), planetary gear set (7), ring gear (5) and shaft (6). Each final drive has the same components. The final drives cause the last speed reduction and the torque increase in the drive train.Three planetary gear sets (7) are mounted in carrier (8).As shaft (6) is driven by the differential, the planetary gears are forced to revolve around the inside ring of the gear. The movement of the planetary gears around the ring gear causes the planetary carrier and the wheel hub to rotate. This transfers power to the rim and the tire which bolts to the flange on the axle shaft.
