What is the function of differential gear mechanism?

What is the function of differential gear mechanism?

Differential gear, in automotive mechanics, gear arrangement that permits power from the engine to be transmitted to a pair of driving wheels, dividing the force equally between them but permitting them to follow paths of different lengths, as when turning a corner or traversing an uneven road.

Which gear used in differential train?

epicyclic gear trains
The epicyclic gear trains are used in the back gear of lathe, differential gears of the automobiles, hoists, pulley blocks, wrist watches etc.

What is the working principle of differential?

The basic technical principle of a differential becomes a problem when the two tires on a driven axle are moving over surfaces that have different traction, such as ice and dry asphalt, for example. The wheel on the ice will spin, while the other will not move at all.

What is the function of differential?

The differential is a set of gears that transmits engine power to the wheels, while allowing them to turn at different speeds on turns.

How many types of differential are there?

There are four types of car differentials and today, the ASE-certified technicians at Christian Brothers Automotive Independence are going to explain them. Our professionals will break down the different types of car differentials and what to expect from each one.

What is the main function of a differential?

As part of the front and/or rear axle assembly, the differential plays an integral role in how your car makes turns. The differential is designed to drive a pair of wheels while allowing them to rotate at different speeds. This function provides proportional RPMs between the left and right wheels.

How do you calculate the gear ratio of a train?

To calculate the gear ratio: Divide the number of driven gear teeth by the number of drive gear teeth. In our example, it’s 28/21 or 4 : 3. This gear ratio shows that the smaller driver gear must turn 1,3 times to get the larger driven gear to make one complete turn.

What are the main parts of differential?

Following are the parts of the differential system: Differential side gear or sun gears….

• Differential Side Gear or Sun Gears.
• Differential Case.
• Pinion Shaft or Cross Pin.
• Axle Shafts or Half Shafts.
• Ring Gear or Crown Wheel.
• Drive Pinion or Bevel Pinion.

What is the main function of differential?

Simply put, a differential is a system that transmits an engine’s torque to the wheels. The differential takes the power from the engine and splits it, allowing the wheels to spin at different speeds.

Where does the differential gear go in a car?

It is a part of the driving axle housing assembly, which includes the differential, rear axles, wheels and bearings. It consists of a system of gear arranged in such a way that connects the propeller shaft with the rear axle and transmit the different torque to rear wheels if necessary.

How does the bevel pinion gear work in a differential?

Differential is an arrangement of gears which work together and allow the vehicle to take a turn smoothly. In the differential, bevel pinion gear is fixed to the propeller shaft which rotates the crown wheel.

What makes a spur gear differential a spur differential?

A spur gear differential is constructed from two identical coaxial epicyclic gear trains assembled with a single carrier such that their planet gears are engaged. This forms a planetary gear train with a fixed carrier train ratio R = -1 .

How is the rotational speed of a differential determined?

A differential is a gear train with three shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. Input torque is applied to the ring gear (blue), which turns the entire carrier (blue).
