A mechanical tool which can transmit torque and rotation through three shafts is known as a differential. Every now and then but not all the time the differential would utilize gears and will function in two ways: in cars, it receives one input and provides two outputs. The other way a differential functions is to put together two inputs so as to generate an output that is the sum, average or difference of the inputs. In wheeled vehicles, the differential allows each of the tires to rotate at various speeds while providing equal torque to each of them.

The differential is intended to drive the wheels with equal torque while likewise allowing them to rotate at different speeds. Whenever traveling around corners, the wheels of the automobiles will rotate at various speeds. Some vehicles such as karts work without a differential and utilize an axle as a substitute. When these vehicles are turning corners, both driving wheels are forced to spin at the same speed, usually on a common axle which is driven by a simple chain-drive apparatus. The inner wheel must travel a shorter distance than the outer wheel while cornering. Without a differential, the effect is the outer wheel dragging and or the inner wheel spinning. This puts strain on drive train, resulting in unpredictable handling, difficult driving and damage to the roads and tires.

The amount of traction required in order to move the automobile at whatever given moment is dependent on the load at that moment. How much drag or friction there is, the vehicle's momentum, the gradient of the road and how heavy the vehicle is are all contributing elements. Among the less desirable side effects of a conventional differential is that it can limit grip under less than ideal situation.

The outcome of torque being supplied to every wheel comes from the transmission, drive axles and engine making use of force against the resistance of that grip on a wheel. Usually, the drive train will provide as much torque as needed unless the load is very high. The limiting factor is usually the traction under each and every wheel. Traction can be interpreted as the amount of torque which can be generated between the road surface and the tire, before the wheel starts to slip. The vehicle will be propelled in the planned direction if the torque applied to the drive wheels does not go beyond the limit of traction. If the torque utilized to every wheel does go beyond the traction threshold then the wheels will spin incessantly.
