  2. POWER TRAIN UNITS

  3. Differential unit

  4. WHAT IS DIFFERENTIAL? • -The differential is designed to drive a pair of wheels while allowing them to rotate at different speeds. • -The differential must be capable of providing torque to both axles, even when they are turning at different speeds for example car turning corner. • -A mechanism that allows torque to be applied to two different gears that can turn at different speeds. In negotiating a corner, the outside wheel of a car must travel farther than the inside wheel in the same amount of time

  5. OPERATION OF DIFFERENTIAL • The propeller shaft turns the ring gear pinion shaft.The ring gear pinion turns the ring gear which, in the turn, revolves the differential case. When the case turns, the differential pinion shaft turns with it. As the differential pinions are mounted on the shaft, they are forced to move with the case. Being meshed with the axle side gears, the pinions with pull the axle side gears along with them. When the car is moving in a straight line, the ring gear is spinning the case. The differential pinions and axle side gears are moving around with the case, with no movement between the teeth of the pinions and axle side gears. The entire movement is like a solid unit.

  6. When rounding a turn, the case continues whirling and pulling the pinions around on the shaft. As the outer wheel must turn faster, the outer axle side gear is now moving faster than the inner axle side gear. The whirling pinions not only pull on both axle side gears, but now begin to rotate on their shaft, mean while walking/in the axle side gears. This allows them to pull on both axle side gears, while at the same time, compensating for difference in speed by rotating around their shaft.

  7. The pinion is pulling both gears, but it is not turning. In the right side axle gear is moving faster than the left axle gear. The pinion gear is still moving at the same speed. It is still pulling on both gears, but has now started to turn on the pinion shaft. This turning action, added to the forward rotational speed of the shaft, has caused the right-hand side gear to speed up and actually begin to pass the pinion shaft.
