What Does A Rear Differential Do

Change the powers direction from longitudinal along the car and direct it to the wheels. The differential is found on all modern cars and trucks and also in many all wheel drive full time four wheel drive vehicles. These all wheel drive vehicles need a differential between each set of drive wheels and they need one between the front and the back wheels as well because the front wheels travel a different distance through a turn than the rear wheels.

The differential doses the power to the two wheels at the exact proportions and speed to ensure that stability is kept to the maximum and strain on the drivetrain differential components and tires is kept at a minimum.

What does a rear differential do. If one wheel is spinning too slowly the mechanism will keep driving the other one. The rear differentials role is simple. If you want to understand more about how this important component works and why it is necessary onehowto is here to tell you just what a car differential does and explain how a differential works. A locking differential is designed to overcome the chief limitation of a standard open differential by essentially locking both wheels on an axle together as if on a common shaft while still allowing them to rotate at different speeds when it is required such as when negotiating a turn.

You have probably heard of a differential but you probably dont know what it does or how it works. To aim the engine power at the wheels to act as the final gear reduction in the vehicle slowing the rotational speed of the transmission one final time before it hits the wheels. The differential mechanism basically allows each wheel to spin freely of the other while providing power to both. In a rear wheel drive car the differential has its own housing and lubrication a thick dark oil usually heavier than 80 weight.

A driveshaft connects the rear differential mechanism to the transmission or transfer case transferring the engines power to the rear wheels. Symptoms of bad or failing differential gear oil. In discussing the spur gear differential the use of the term annular gear is a convenient way to distinguish the sun gears of the two epicyclic gear trains. What does the rear differential do.

What does a rear differential do. Allowing them to do their jobs safely and smoothly. The differential has three jobs. Front drivers typically integrate the differential in the transmission housing and share the same fluid.

The second sun gear serves the same purpose as the annular gear of a simple planetary gear train but clearly does not have the internal gear mate that is typical of an annular gear. Symptoms of bad or failing differential gear oil if your car has exceeded its gear oil service interval or if you hear the differential whining you may need to replace the differentialgear oil.
