Automatic Transmission / automobile gearbox /Automatic Transmission Modes/ Automatic Transmission Parts

 Automatic Transmission:          An automatic transmission (commonly "AT" or "Auto") is an automobile gearbox that can change gear ratios automatically as the vehicle moves, freeing the driver from having to shift gears manually.  Automatic Transmission Modes:          In order to select the mode, the driver would have to move a gear shift lever located...

What is Differential Unit ? How Differential Unit work.

 Differential Unit:Differentials are a variety of gearbox, almost always used in one of two ways. In one of these, it receives one input and provides two outputs: this is found in every automobile. In automobile and other wheeled vehicles, the differential allows each of the driving wheels to rotate at different speeds, while supplying equal torque to each of them. In the other, less commonly encountered, it combines two inputs to create an...

HOW DRIVE SHAFT WORK

 The Drive Shaft.The drive shaft, or propeller shaft, connects the transmission output shaft to the differential pinion shaft. Since all roads are not perfectly smooth, and the transmission is fixed, the drive shaft has to be flexible to absorb the shock of bumps in the road. Universal, or "U-joints" allow the drive shaft to flex (and stop it from breaking) when the drive angle changes.Drive shafts are usually hollow in order to weigh less,...

HOW U-Joint WORK ?

 U- Joint:Hooke's joint is a linkage that transmits rotation between two non parallel shafts whose axes are coplanar but not coinciding., and is commonly used in shafts that transmit rotary motion. It is used in automobiles where it is used to transmit power from the gear box of the engine to the rear axle.The driving shaft rotates at a uniform angular speed, where as the driven shaft rotates at a continuously varying angular speed.   ...

HOW INTERCOOLER WORKS

 HOW INTERCOOLER WORKS An intercooler is a heat exchanger that’s fitted between the engine’s super or turbo charger and the intake manifold. Its job is to absorb and dissipate the heat in the charge air in order to provide the engine with the coolest and most dense air possible. Air has a mass or a weight that changes based on the temperature and pressure of the air. The lower the temperature – the higher the mass. The higher the pressure...

What is alternator and what works?

 What is alternator and what works? An alternator is a type of electrical machine that converts mechanical energy into alternating electric energy.  Hence it is also called synchronous generators or AC generator.  If you have a car or a heavy and big vehicle, then if your headlights are slightly dimmed, and your car is not always starting.  And you are worried because what is the reason for this, then maybe the cause of alternator...

STARTING SYSTEM: COMPONENTS AND WORKING PRINCIPLES

STARTING SYSTEM: COMPONENTS AND WORKING PRINCIPLESThe engine can’t “start” rotational movement on its own. It needs an electric motor to get it up to a minimal RPM to run, then the engine can run under its power. The starter is the biggest load on the vehicle's electrical system. We cannot simply run all that current through the ignition switch, in most systems a relay is used to activate the starter solenoid, and the starter solenoid itself acts...
