Question

What is the necessity of Gearbox in automobile transmission system?​

Answer 1

Answer:

Most modern gearboxes are used to increase torque while reducing the speed of a prime mover output shaft (e.g. a motor crankshaft). This means that the output shaft of a gearbox rotates at a slower rate than the input shaft, and this reduction in speed produces a mechanical advantage, increasing torque.

Answer 2

The necessity of gearbox in automobile transmission system is as follows -

• The transmission system of the modern vehicles is used for transferring the rotational motion of the main engine to the shafts of the front and rear wheels,in a controlled manner.

• The gearbox is used in the transmission systems because we use the principle of the gear ratio mechanism to transfer the rotational motion to the front and back wheels,in a controlled manner.

• In this way, we are able to precisely control our vehicle in a power efficient manner.
