A gearbox (also called a transmission) provides speed and torque conversions from a rotating power source to another device using gear ratios. It can be used in various situations, such as stationary machines, pedal bikes and anywhere else where it is necessary to adapt the rotation speed and torque. But the most common place is in motor vehicles, where the gearbox adapts the output of the internal combustion engine to the drive wheels. Because these motors must run at a relatively high rotational speed, they cannot be used for many operations, such as starting or stopping.

Since gearboxes are so widely used in motor vehicles, it is obvious that they must be used extensively in automobiles. With the development of our economy, more and more cars are consumed, as a result, gearboxes are playing a more important role in our daily life. Although many people own cars, few have the knowledge of how a car works, much less the relationship between the different mechanical components. Since car gearboxes are the critical parts of their work process, it is a wise decision for car owners to learn something about gearboxes.

In cars, the gearbox will generally be connected to the engine crankshaft. And the transmission’s output is transmitted through the driveshaft to one or more differentials, which in turn drive the wheels. The gearbox converts the engine speed into torque that will push the car forward. It is the main job of the gearbox. There is some difference between manual and automatic cars. For example, in a manual car, when the driver presses the clutch, the gear disengages from its original position so that it can slide up and down in the gearbox, while automatic gearboxes are the opposite.

As the main task of the gearbox is to convert the engine speed into torque to push the car forward, it is essential for your car. Your car won’t go anywhere if you don’t have the gearbox. As a result, you need to pay more attention to gearboxes. Since we are talking about gearboxes, it is necessary to mention the gear ratios. Typically, a gearbox will have multiple gear ratios, with the ability to shift between them as speed varies. And this change can be done manually or automatically.

There is no doubt that gearboxes can be used in many other places, except in cars. But no matter where they are used, these transmissions share one important feature, namely the gear ratio cannot be changed during use. It is because the gear ratio is fixed at the moment the transmission is established.

All in all, there is more knowledge about gearboxes and their functions. It is recommended that you have some basic knowledge of gearboxes. Perhaps it will be useful in your future life.
