Transmission, Automotive Chassis and Transmission

This chapter covers a total of 10 % from your syllabus. Here, you'll get to know about all the most important topics and concepts that are useful and will be coming surely into the exams. Here the language of the concepts is kept easy to make it easier for you to understand everything.


* Necessity of Transmission:


A car’s transmission uses the power of the vehicle to move the engine at various speeds. There are two designs or types of transmissions; automatic and manual. Automatic vehicles perform all of the work for you such as shifting from precise operating systems. While manual transmissions are run entirely by the driver. Drivers must know that when the maximum gear range is reached in order to shift without ruining the vehicle’s transmission, which is a costly part to replace.


* The major function of any transmission is to transfer engine power to the driveshaft and rear wheels (or axle halfshafts and front wheels in a front-wheel-drive vehicle). Those gears inside the transmission change the vehicle's drive-wheel speed and torque in relation to the respective engine speed and torque.

* Types of transmissions:


1.  Automatic Transmission:

This widely-used automatic transmission can be found in most of the car. This transmission uses a hydraulic fluid coupling or a torque converter to do the job of changing gears instead of the clutch. The ECU (or engine control unit) is directly connected to this mechanism to allow a smooth and precise engine control of the vehicle.

2. A manual transmission sliding mesh is usually found in older vehicles. It is, in fact, from one of the oldest types of gearbox. To shift between different speeds or torque ratios using a sliding-mesh gearbox, the gears on the main shaft are shifted right or left for meshing them with the appropriate gears on the counter shaft (and this is where the phrase ‘shifting gears’ comes from).

3. A manual transmission constant mesh, meanwhile, is common in newer manual transmissions – notably in large trucks and farm vehicles. All of the gears here mesh together simultaneously and at all times. In other words, the gears rotate freely on the main shaft, and the gear ratios are selected by clutches that connect them to shafts to power the vehicle.
