نواقل الحركة النهائية

Final drive transmits the power delivered from the propeller shaft to the drive wheels or to sprockets equipped on track laying equipment. Because it is located in the rear axle housing, the final drive is usually identified as a part of the rear axle assembly. The final drive consists of two gears, called the ring gear and pinion. The function of the final drive is to change by 90 degrees the direction of the power transmitted through the propeller shaft to the driving axles. It also provides a fixed reduction between the speed of the propeller shaft and the axles driving the wheels.
