(14) Spindle housing Each of the two final drives has the same components. A final drive causes the last speed reduction in the power train and the last torque increase in the power train.Spindle housing (14) is fastened to the axle housing. Hub (4) is splined to spindle housing (14) and to ring gear (5). Ring gear (5) is splined to ring gear (7). Ring gear (7), ring gear (5), hub (4), and spindle housing (14) are stationary.The axle shaft is connected to the differential by spindles in sun gear (12). Sun gear (12) is engaged with planetary gears (6). Planetary gears (6) are held in planetary carrier (8). Planetary carrier (8) is connected to sun gear (11) by splines. Sun gear (11) is engaged with planetary gears (9). Planetary gears (9) are held in planetary carrier (10). Planetary carrier (10) is connected to wheel (13).Power from the differential turns the axle shaft. The axle shaft turns sun gear (12). Sun gear (12) turns planetary gear (6). Because ring gear (5) is held stationary by hub (4), the planetary gears move around the inside of ring gear (5). The movement of the planetary gears causes planetary carrier (8) to turn. Carrier (8) is turned in the same direction as sun gear (12), but at a slower speed. Carrier (8) turns sun gear (11). Sun gear (11) turns planetary gear (9). Because ring gear (7) is held stationary by ring gear (5), the planetary gears move around the inside of ring gear (7). The movement of the planetary gears causes planetary carrier (10) to turn. Carrier (10) is turned in the same direction as sun gear (11), but at a slower speed. Carrier (10) drives wheel (13).The final drives receive lubrication by the rotation of the gears in the oil. The differential and the final drives use the same lubricant.
