The transmission is an important system responsible for the adequate functioning of the car. This system transports power generated by the engine to the wheels. Therefore, without an adequately working transmission system, there will be no movement in the car.
In this guide, we will provide you with complete information about the car transmission system and its working.
Car Transmission System
Power generated by petrol and diesel engines is in rotation motion. This rotation of the crankshaft is transmitted to wheels through a rod. The friction between the rod and crankshaft makes it possible to transmit power. Thus, all the components involved in it are collectively known as transmission system of cars.
Here we have provided all the details about gear power transmission system.
Components
The power transmission system is dependent upon a number of elements for adequate functioning. We have enlisted some of the most significant elements that are part of the transmission system in automobiles.
- Gear: It is responsible to manage the engine’s power generating along with the speed of the wheels
- Gear Ratio: It is the ratio at which the input and output set of gears rotate
- Clutch: A connection between the vehicle and transmission system
- Transmission: Transfer of power from vehicle’s engine to its axle (wheel)
- Shift Lever: A lever used to manage the current gear by the driver
Working
There are different types of car transmission systems but they all work on the same principle. The only difference that a transmission type can make is the effort of the driver. Here we have elaborated the basic working principle of the transmission system.
- To connect with gears, a lever moves and selects a gear. If it is a manual system the driver will operate it through the clutch pedal. However, with an automatic transmission system, everything is done automatically.
- Once these gears are engaged, it will move forward to connect with clutch plates for engaging with larger gears. These larger gears are then connected to the differential of the car.
- When the gear moves, different gears are engaged at different times to transmit the necessary power from the engine to the wheels.
This simple process of engaging and disengaging gears is the working principle of the car power transmission system.
Functions
The car transmission system is not only responsible for engaging gears and transmitting power, but it also performs other major functions. Some of these functions are listed below.
- Variable Speed: The speed varies greatly, but the engine works at the same capacity. The transmission system is responsible for providing the required amount of energy at different speeds.
- Deceleration and Torque Increase: The engine provides higher speed and lower torque to the transmission system which is not useful in smooth car functioning. The transmission system converts it into lower speed and higher torque through the drivetrain.
- Reversing: The engine is not capable of reversing the amount of energy it has transferred once. Therefore, the transmission system is used to manage energy and reverse the vehicle.
Types of Car Transmission System
There are different types of car transmission systems. These systems are designed keeping in view the basic principle of transmission systems, but few additional steps and features are included.
The two most common types of transmission systems are manual and automatic transmission systems. However, there is a third type of transmission system which is rarely used.
Manual Gear Transmission System
In a manual transmission, there is a lever and clutch pedal to change gears when driving a manual car. This system uses an outer shaft, inner shaft, pressure plate, flywheel, and clutch to run the whole system. The manual transmission is often criticized for a bumpy feeling when changing gears, but it is efficient to achieve higher speed in less time.
Automatic Gear Transmission System
The automatic transmission system exempts clutch and uses a torque converter for changing gears. This technology has been present since the 1900s, but technological advancements have changed its working a lot.
CVT Gear Transmission System
The Continuously Variable Transmission (CVT) system works on a pulley system and often aligns with smaller engines. It contains lesser components contrary to an automatic and manual transmission. This type of transmission system is used in hybrid cars.
This was all about the car transmission system that is used for the transfer of power. Without a transmission system, engine efficiency will be reduced to a minimum and car functioning will become more difficult.
The construction of the transmission system is complex, and fixing a faulty one is nearly impossible. Moreover, it will require proper professional assistance and care after repairing. You can avoid this hassle, by browsing through these used cars for sale in the UAE.
