What is differential work in automobile?
The differential is a system of gears that allows different drive wheels (the wheels to which power is delivered from the engine) on the same axle to rotate at different speeds, such as when the car is turning.
What is the mechanism of differential?
The differential mechanism allows the wheels to rotate at different speeds while getting the drive. Thus, it makes possible the independent rotation of wheels while maintaining the drive. The differential mechanism works on the simple principle of a weighing beam. A differential is a set of gears having three shafts.
What is the function of a differential in automobile transmission?
With automobiles and other wheeled vehicles, the differential allows the outer drive wheel to rotate faster than the inner drive wheel during a turn. This is necessary when the vehicle turns, making the wheel that is traveling around the outside of the turning curve roll farther and faster than the other.
Where is the differential in a car?
With front-wheel-drive (FWD), the differential is alongside the transmission inside a housing, and the unit is called a transaxle. With rear-wheel-drive (RWD), the differential is between the rear wheels, connected to the transmission by a driveshaft.
What type of gears are used in a differential of an automobile?
The compound gear train shown in the figure below consists of compound gear B-C and D-E. All gears are mounted on parallel shafts. The motor shaft rotating at 800 rpm is connected to the gear A and the output shaft to the gear F.
What are different parts of differential?
Parts of Differential
- Differential side gear or sun gears.
- Pinion shaft or cross pin.
- Axle shafts or half shafts.
- Ring gear or crown wheel.
- Drive pinion or bevel pinion.
- Differential pinions or planet gears.
- Differential case or Housing.
What are the advantages of using differential in an automobile?
Advantages of Differential:
- Inspite of large amount of power delivered from the transmission system,the differential reduces the speed w.r.t. its movement in the right or left direction.
- It turns the flow of power by 90 degrees.
What is the purpose of a differential?
The differential is a system that allows the drive wheels to turn at different speeds, which is required when the car is negotiating a turn. In a turn, the outside wheel must travel farther, which means it must travel faster than the inside wheels.
Which gear is used in differential?
The differential case is mounted with two-wheel axles and differential side gears. The differential case has bearings that rotate two axle shafts. Then, the two pinion gears and their supporting shaft, called pinion shafts, are fitted into the differential case.
