Here we present a simplified explanation of how and why an automobile differential works. The car is turning about a circle with nominal radius r n

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 √ TYPES OF GEAR USED IN DIFFERENTIAL: • Type of gear used in an automobile differential is known as the planetary gear, where a set of gear trains operates in a coordinated manner. • fig. 1.2 shows the actual differential gearbox which is given below A differential gear ensures that the inner wheel rotates to the same extent more slowly as the outer wheel rotates faster when cornering! 3rd step - Replacing pins and bars with bevel gears. The power transmission by pins and bars is not very effective The differential does the final gear reduction and the torque split between the right and left wheels. If the vehicle is driving on a straight line, only the final gear and bearings are adding power losses. There are 3 bearings (one on the input pinion, one on the left output shaft and one on the right output shaft) and 1 spiral bevel gear A gear train is a mechanical system formed by mounting gears on a frame so the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next

The Purpose of Differential is providing rotation of a drive wheels with different speed. Types of differential in automobile. There are three main types of Differential in automobile: gear differential; gearless differential; worm gear differential. Differential can be usual or controlled central differential (limited slip differential) On the inner ends of each axle a smaller bevel gear called differential side gear is mounted. Two bevel gears are put together to mesh both driving and driven shafts at an angle of 90°. The differential case is mounted with two-wheel axles and differential side gears. The differential case has bearings that rotate two axle shafts 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. The crown wheel has another unit called the differential unit Parts Of Epicyclic Gear train The epicyclic gear trains are useful for transmitting high-velocity ratios with gears of moderate size in a comparatively lesser space. The epicyclic gear trains are used in the back gear of lathe, differential gears of the automobiles, hoists, pulley blocks, wristwatches, et

differential is placed halfway between the driving wheels, on either the front, rear, or both axes (depending on whether it's a front-, rear-, or 4-wheel-drive car). In rear-wheel drive cars, the differential converts rotational motion of the transmission shaft which lies parallel to the car's motion to rotational motion of the half-shaft The crown wheel gear is attached to the differential carrier orcage, which contains the sun and planet wheels or gears, which are a cluster of four opposedbevel gears in perpendicular plane, so each bevel gear meshes with two neighbours, and rotatescounter to the third, that it faces and does not mesh with The differential gear in the automobiles is used to [A]. Reduce speed [B]. Assist in changing speed [C]. Provide jerk free movement of vehicl These gears were used as a differential torque gear to assist in moving chariots. This gear assemble forces the wheels of a chariot to move as one unit. Some of the earliest known gears were made from wood Working of Differential :- So, first the power is transferred from engine's drive shaft to pinion gear, since the pinion gear & ring gear are meshed, power flows to ring gear.As the spider gear is connected with the ring gear, power flows to it. Finally from the spider gear, power gets transferred to both the side gears

Avoid Serious Consequences With Attentive Repair. Many common problems with differentials can snowball into major headaches if you don't deal with them in a timely manner The drive train of a vehicle refers to the group of components that act to deliver power to the driving wheels of a vehicle. The power to run a vehicle starts in the crankshaft. It is then delivered to the clutch, via the flywheel (in a manual transmission), or to a torque-converter (in an automatic).Power then goes to the transmission, where it is redirected to the drive shaft (also called.

If you replace a differential on your car, you shouldn't proceed to drive away immediately as if nothing's new. Engineering Explained's Jason Fenske lays out the break-in procedure for a new. Another differential from an early motor-car, with a view of the inside. This car was chain-driven, and sprockets on the housing (of which two are visible) take tke place of the crown gear. The images of early differentials are taken from The Automobile Instructor by Clyde H. Pratt, Shrewsbury Publishing Co., Chicago 1917 You need both speed as well as traction while driving an automobile. The gears in the gearbox help you choose either of them depending on the driving conditions. The lower gear, i.e., 2nd and 1st gear, will give you the greatest traction, while the higher gears, i.e., 5th and 6th (if available), will give you the highest speed
