A gearbox (also called transmission) provides speed and torque conversions from a rotating power source to another device using gear ratios. It can be used in numerous situations such as fixed machines, pedal bicycles, and anywhere else rotational speed and torque needs to be adapted. But the most common place is in motor vehicles, exactly where the gearbox adapts the output of the internal combustion engine to the drive wheels. Because these engines require to be operated at a fairly high rotational speed, they can not be used in many operations such as beginning or stopping.As gearboxes are so widely used in motor vehicles, it is obvious that they should be largely used in cars. With the development of our economy, more and more cars are consumed, as a outcome, gearboxes are playing much more important function in our every day life. Even though many people have vehicles, few of them have the knowledge of how a car works, let alone the partnership between various mechanical elements. Because car gearboxes are the basic components for its working process, it is a wise choice for car owners to learn some thing about gearboxes.In cars, the gearbox will generally be connected to the crankshaft of the engine. And the output of the transmission is transmitted via driveshaft to 1 or much more differentials, which in turn drive the wheels. The gearbox converts engine speed into torque which will push the car forward. It is the primary job of the gearbox. There is some distinction between manual cars and automatic cars. For instance, in a manual car, when the driver depresses the clutch, the gear will be disengaged from its original position so that it can slide up and down the gearbox, whilst automatic gearboxes are the opposite.As the primary job of the gearbox is to convert engine speed to torque so as to push the car forward, it is indispensable for your car. Your car will not be going anyplace if it lacks the gearbox. As a result, you should pay much more attention to the gearboxes. Since we are speaking about gearboxes, it is essential to mention the gear ratios. Generally, a gearbox will have multiple gear ratios, with the capability to switch in between them as speed varies. And this switch may be carried out manually or automatically.There is no doubt that gearboxes can be used in numerous other places except in vehicles. But no matter exactly where they are used, these transmissions share an essential function, i.e. the gear ratio can’t be changed throughout the usage. It is simply because the gear ratio is fixed at the time the transmission is set.All in all, there is more knowledge about gearboxes and their functions. It is advisable that you ought to have some basic knowledge of gearboxes. Perhaps it will be helpful in your future life.Do you have any suggestions on the Ford transit 6 speed gear box, please do not think twice to contact us.
