THE BRAIN BEHIND CAR TRANSMISSION

An automobile requires high torque when climbing hills and when starting, even though they are performed at low speeds. On other hand, when running at high speeds on level roads, high torque is not required because of momentum.  So requirement of a device  occurs, which can change the vehicle’s torque and its speed according to road condition or when the driver needs it. This device is known as transmission box or A gearbox.

Function of transmission box (gear box) in automobile:

The transmission box which is also known as the gear box is the second element of the power train in an automobile. It is used to change the speed and torque of vehicle according to variety of road and load conditions.

Transmission box change the engine speed into torque when climbing hills and when the vehicle requires it. Sometimes it is known as torque converter.

Main functions of a gear box is as follow:

1. Provide the torque needed to move the vehicle under a variety of road and load conditions. It does this by changing the gear ratio between the engine crankshaft and vehicle drive wheels.

2. Be shifted into reverse so the vehicle can move backward.

3. Be shifted into neutral for starting the engine.
