A vehicle's gearbox is also called a transmission system and uses gears, actuating parts and shafts to transfer power from the engine to the wheels. Simply put, it is a box containing gears.
You can find gearboxes in everything from heavy machinery and turbines to automobiles. This blog will focus on the different types of gearboxes in automobiles.
It is the gearbox that helps a driver maximise and minimise torque. In automobiles, a gearbox is a metallic box surrounding various combinations of gears. Each gear is of a different size, with the first one being the largest and providing the maximum torque and minimum speed.
A driver can select different gears by using a movable gear selector. He or she can select a gear that changes the torque output and speed of a car’s motor. When the configuration of gears is changed, an output shaft connected to the gearbox changes its output torque and speed.
A car requires different levels of torque at different conditions to function well. For example, when a vehicle is climbing up a hill, it requires more torque because of a higher friction load, which demands more fuel consumption. However, it requires less torque when it has gained sufficient velocity. In such a situation, a driver can reduce fuel consumption by reducing the torque.
This gearbox is also referred to as a stick-shift unit or standard transmission. The driver must manually shift the gears with a clutch and movable gear selector. This transmission is present in most vehicles due to its low costs.
Features: Sliding gear transmission, constant mesh transmission, and pre-selector transmission are some different types of manual gearboxes. Given are some important points about these gearboxes.
How It Is Useful: The manual transmission gearbox lets a driver control the gears fully. It allows the driver to use his skills in choosing suitable gear to save fuel. It also helps him to make progress quickly.
More people are choosing to use DCT automatic transmission systems, so it has become a common gearbox for diesel and petrol cars. There are two clutches in these types of gearboxes—one for the odd-numbered gears and another for the even-numbered gears.
Features: Listed below are the features of this gearbox:
How It Is Useful: This gearbox is present in many performance cars where the gear changes are nearly indistinguishable. In addition, if the car has a dry-clutch DCT, there will be no fluid pumping losses resulting in greater fuel efficiency.
This is an automatic transmission system where the driver does not shift gears physically. It is a widely used gearbox called a torque converter that enables the car to stop even when the engine is functioning.
Features: The features of a torque converter automatic gearbox are as follows:
How It Is Useful: The most important benefit of this transmission system is that it facilitates smooth acceleration from low speeds and good responsiveness even at low engine revs.
This manual gearbox has an electronically or hydraulically controlled actuator that shifts the gears automatically. It uses a regular clutch, gear configuration, sensors, processors, actuators, and pneumatics.
Features: The following are some important features:
How It Is Useful: An important advantage of this type of gearbox is its high fuel efficiency. Moreover, it ensures high fuel mileage if you are travelling long distances.
This automatic gearbox is also known as a pulley or step-less transmission system. CVT gearboxes do not depend on torque for functioning. Instead, it uses gear ratios for transferring for powering up the vehicle.
Features: The following are some important features of these gearboxes:
How It Is Useful: A CVT is beneficial for hybrid cars that use this transmission system to effectively balance the workload between an electric motor and a petrol engine. This relatively new system is undergoing many improvements, so the next versions could likely be considerably better.
Given below are the main points of how the gearbox functions:
We have listed the important types of gearboxes used in most cars. While previously, people would use manual transmission systems, science and technology have given rise to many more gearboxes like the DCT automatic system, CVT automatic system and torque convertor automatic system. These make driving a lot more convenient and safer.
