(13) Carrier.The front axle and the rear axle incorporate the pinion gear, the differential and the final drive. The disc brakes are located in the rear axle and the front axle. The limited slip differential is available in the front axle and the rear axle.The oscillating axle can oscillate up to eleven degrees. With larger tires, stops for oscillation are required.Power from the hydrostatic drive box turns the bevel pinion in the rear axle. The power at the rear oscillating axle is transferred to the front fixed axle by the drive shaft. The power enters the axles through bevel pinion (1). Bevel pinion (1) turns bevel gear (9), which is fastened to differential case (6) .The main components of the final drives are carrier (13), planetary gear (4), ring gear (3) and sun gear (10). Each final drive has the same components. The final drives cause the last speed reduction and the torque increase in the drive train.Power is transferred through the differential by pinions (7) and side gears (2) to the final drives. Sun gear (10) is splined into side gear (2) of the differential. Ring gear (3) is pressed into the axle housing. Three planetary gears (4) are mounted in carrier (13). Carrier (13) is splined to axle shaft (5) .As sun gear (10) is driven by the differential, planetary gears (4) are forced to revolve around the inside of ring gear (3). The movement of planetary gears (4) around the ring gear (3) causes carrier (13) and axle shaft (5) to rotate. This transfers power to the rim and the tire which bolts to the flange on axle shaft (5).
