Most Interesting Facts About Transmission System of a Vehicles

If you haven’t gone through our first article of Automobile Series. We recommend you to have a look at that one i.e An Introduction to the Electrical Vehicles Part-1.
When a car moves on the road, the road shows its nature. Also, Sometimes it becomes rude with the vehicle or sometimes it behaves gently with the car. In this scenario, a mechanism of the vehicle is introduced to negotiate with the road. It gives the proper torque to the vehicle on the off-road or increases the speed of the wheels in the case of the plane smooth road. This mechanism is called the transmission system. It is the power delivery system of the car which transmits the power from the engine to the wheels.  And it maintains the torque and speed in the delivered power as per the road needed. But is this the only reason for using a transmission system…..absolutely NOT. There is an another reason for existing a transmission system in a vehicle. let’s know why a transmission system is used in a car.

#STARTS WITH ENGINE
Before knowing about the gearbox let’s move one step back from the transmission system. Actually, the main problem arises in the engine. And the problem is it can’t provide the maximum torque for a wide range of engine speed. The range also varies from engine to engine, car to car. And it starts around 1500-2000rpm, ends around 5000-6000rpm. But the cars need a higher rpm.But going for beyond specified rpm increases the fuel consumption and also causes some major mechanical damage to the engine.If an engine is directly connected to the differential then it will not even able to provide necessary starting torque to the wheel as at low rpm it has a low torque, at the same time the car can’t achieve a higher speed for the mechanical limitations.

#WHAT DOES A TRANSMISSION SYSTEM DO IN THIS CASE???
So to avoid the above problem transmission system is set up between the engine and the wheels. The engine is operated at the desired conditions where the torque is maximum and the fuel consumption is minimum. And all the task is completed by the gearbox. In the case of starting mode or when the vehicle runs on the off-road or when it carries heavy load transmission system increases the torque within the given maximum power offered by the engine.
As we know
power =torque *speed
transmission
So when the torque is increased simultaneously the speed is reduced.When the car needs a high speed then gearbox increases the speed and decreases the torque. In this way, a transmission system acts a major role to energize the wheels of a car.

#HOW THEY DO IT????
The mechanical architecture of a transmission system is different for different types of the transmission system.Some gearbox consists of meshing of gears and some come with the belt and dual clutch.Every gearbox has some benefits and demerits.So the selection of gearbox depends on the applications and types of vehicles in which they are used.

   This is the introductory part of the transmission system of a vehicle. Next time our article will be based on the description of modern transmission systems that are used vastly in many modern cars. And I am sure that this information will help u in understanding the difference between the transmission system of an IC engine car and an electric car.

    Very informative yet simple .Could have been better if the graphs were a bit clearer,keep the good work.Waiting for the next one
