Introduction: ➢ The power developed inside the engine cylinder is ultimately transmitted to the driving wheels so that the motor vehicle can move on the road. This mechanism is called power transmission. ➢ It consists of clutch, gearbox, universal joint, propeller shaft, final drive, and axle shaft. General arrangement of power transmission system (or) front engine rear wheel drive: ➢ Fig (1) shows that layout of the front engine rear wheel drive. 3 ➢ Power is produced i n s i d e the engine cylinder transmitted to flywheel through crankshaft. ➢ Clutch is conduct with flywheel to engage and disengage drive from the engine to gearbox. ➢ Gearbox consists of s set of gears to change the speed. ➢ The power is transmitted from the gearbox to the propeller shaft through the universal joint and then to the differential through another universal joint. ➢ Finally, the power is transmitted to the rear wheels through the rear axles. Front engine front wheel drives: Fig (2): shows that layout of the front engine front wheel drive. ➢ In this drive the clutch, gear box, differential is arranged in a common housing. ➢ In this arrangement there is no need of separate long propeller shaft for transmitting power to the rear wheels. ➢ Because the engine power is transmitted only for front wheels alone. ➢ Rear axle is dead axles, when front wheels are rolling with power and rear wheels are freely move in the direction of front wheels. 4 Rear Engine rear wheel drive: Fig (3): shows that layout of the rear engine front wheel drive.

  • Automobile Engineering
    A Course Material on Automobile Engineering By Mr. T.Manokaran ME,MBA ASSISTANT PROFESSOR DEPARTMENT OF MECHANICAL ENGINEERING SASURIE COLLEGE OF ENGINEERING VIJAYAMANGALAM – 638 056 Author Page At first I like to submit my sincere thanks to GOD, PARENTS and FRIENDS who have helped and encouraged me to prepare this entire course material for the subject of Automobile Engineering. Automobile Engineering is a vast field encompassing different types of vehicles used for transportation of people and materials. It is very difficult to cover all the aspects of automobile engineering in single notes, because vehicles are being refined and improved day by day. However an attempt is made in this course material to give the maximum possible details of fundamentals of the automobile vehicles. It is always challenging to decide whether historical notes should come before or after the description and interpretation of the state of the art. Arguing for the second alternative is the fact that readers should already have understood the motivations that drive a design decision. We begin this chapter with basis of automobile, and through by the transmissions and steering systems, going on later to describe wheels, tires and braking & suspension systems. This emphasis is solely due to the larger impact that suspensions and steering systems have on vehicle architecture and its consequent evolution; steering systems will be described together with suspensions because these two systems are indissoluble from the point of view of designers. Knowing is not enough, We must apply. Willing is not enough, We must do. ALL the BEST T.Manokaran ME,MBA Assistant Professor Department of Mech.Engg.

  • Unit-Iii Transmission System
    UNIT-III TRANSMISSION SYSTEM TRANSMISSION SYSTEM Chief function of the device is to receive power at one torque and angular velocity and to deliver it at another torque and the corresponding angular velocity. LAYOUT OF AUTOMOBILE POWER TRANSMISSION SYSTEM REQUIREMENTS OF TRANSMISSION SYSTEM 1. To provide for disconnecting the engine from the driving wheels. 2. When the engine is running, to enable the connection to the driving wheels to be made smoothly and without shock. 3. To enable the leverage between the engine and driving wheels to be varied. 4. It must reduce the drive-line speed from that of the engine to that of the driving wheels in a ratio of somewhere between about 3:1 and 10:1 or more, according to the relative size of engine and weight of vehicle. 5. Turn the drive, if necessary, through 90° or perhaps otherwise re-align it. 6. Enable the driving wheels to rotate at different speeds. 7. Provide for relative movement between the engine and driving wheels. CLUTCH The clutch is housed between the engine and transmission where it provides a mechanical coupling between the engine's flywheel and the transmission input shaft. The clutch is operated by a linkage that extends from the passenger compartment to the clutch housing. The purpose of the clutch is to disconnect the engine from the driven wheels when a vehicle is changing gears or being started from rest. Disengaging the clutch separates the flywheel, the clutch plate and the pressure plate from each other. The flywheel is bolted to the end of the crankshaft and rotates with it.

Luckily for us independent service providers, Mercedes-Benz has done an exceptional job engineering and building a remarkable, mostly problem-free driveline.

  • Rear Axle Operation the Differential
    Rear Axle Operation Below is an overview of rear axle operation The Differential The differential is the thing that works both drive axles at the same time, but lets them rotate at different speeds so that the car can make turns. When a car makes a turn, the outer wheel has to turn faster than the inner wheel, due to the difference in the length of the paths they take. The differential is located between the two wheels, and is attached to each wheel by a half-shaft rotated through a bevel gear. Four- wheel drive cars have a separate differential for each pair of wheels. A grooved, or splined, axle side gear is positioned on the splined end of each axle. The side gears are driven by "spider" gears, which are little gears mounted on a shaft attached to the differential case. As it is supported by the differential case, the side gear can turn inside the case. The differential case can be turned, revolving around the axle gears. The differential pinion (a pinion is a small gear that either drives a larger gear or is driven by one) shaft turns the ring gear, which is fastened to the differential case. The propeller shaft (drive shaft) connects the transmission output shaft to the differential pinion shaft. The turning differential case is mounted on two large bearing holders. These bearings are called carrier bearings. The propeller shaft rotates the ring gear pinion, and the pinion turns the ring gear. The ring gear then turns the differential case and pinion shaft, but the axle side gears will not turn.
