The gearbox is one of the items that make up the vehicle's transmission system, which is responsible for transmitting power, rotation and torque from the engine to the wheels. The entire vehicle's power is generated by the engine, which distributes it to the different vehicle components, making the entire system work. The components of the automotive transmission system correspond to the clutch, gearbox, differential and transfer case. The gearbox, the target item of our conversation, is the component that, during the power transmission process, acts to overcome the vehicle's load demand. In other words, the gearbox allows the engine to supply power to the wheels, according to need. This item usually has five gears. However, some new vehicle models already have gearboxes with six manual gears or eight to ten gears in cars with automatic transmission. There are usually many questions regarding gear changes, as well as when to downshift. For this reason, in this article, if you are part of the group that has this type of doubt, we will talk about the subject. First, I will discuss the types of gearboxes, as well as the functions that each gear has. This way, we can talk about your doubts regarding gear changes and, consequently, the right time to downshift. Types of Gearboxes The gearbox is one of the most important parts of a vehicle, being responsible for transmitting power from the engine to the wheels. The first automobiles had a very simple transmission mechanism, consisting of chains. Over time, gears and gearboxes appeared, initially consisting of three gears, and, at the beginning of the 20th century, the H-shaped gearboxes, a model that we still have in vehicles today. Many people choose their vehicles based on the type of transmission, as they can offer surprising conveniences. There are four different types of transmissions and each one has a specific type of functionality. Manual or mechanical transmission This type is the most common among cars in Brazil. It has manual operation and requires the use of the clutch to change gears, which is done by the driver using the lever located between the two front seats. Double-clutch automated transmission The gear change in the double-clutch automated transmission is carried out in the same way as in vehicles with manual transmission. However, the driver does not need to perform any type of movement to change gear. This is because the transmission box works with two gears. Therefore, when the gear change is made, the gear is already ready to engage the next gear. Automatic transmission This model has a new technology, which does not require the driver's intervention, since it works directly with the engine. With a set of discs that represent the gears and an item called a torque converter in place of the clutch, the automatic transmission works continuously and prevents the car from making the famous “jerks”. CVT (Continuously Variable Transmission) Also known as an infinite-speed transmission, this is the most modern and expensive of the models. The CVT transmission is connected directly to the engine and the car’s axles, keeping the car’s acceleration and deceleration force constant. The transmission model directly influences the value of the vehicles, since, as you can see, it provides numerous and different advantages to the driver. For this reason, when purchasing a vehicle, it is important that you have in mind what you really want and, thus, choose the transmission that satisfies not only your comforts, but also your financial conditions. Now that you know the types of car gears, it is time to learn what they do. In the next section, you will find out.
