The transmission gears and shafts  are vital parts of the transmission system of a vehicle. It plays the main mechanical role in transforming the fuel energies to the useful power that helps the engine to take the vehicle forward. These gears and shafts supply adequate powers to the wheels and this procedure is on until the engine is stopped.

  The role of the gear

The gear is meant for the two mechanical activities- speed and torque in a vehicle. The gear ratio controls the speed of the vehicle. If the ratio is high, the vehicle takes high speed and if the ratio is low it slows down the car increasing the torque. In this way, the speed and torque maintain a balance in automation of any vehicle.

 The role of the shafts

As a part of the transmission system, it is connected to the crankshaft in the engine. The extra-transmitted power goes through the drive shaft and thus helps the vehicle to move forward.

In short, the transmission gears and shafts work together in the matter of driving a car. The amount the gear transmits the power to the wheels while the shafts input the direction causing increasing and decreasing the torque.
