What does a gearbox do?
The purpose of a gearbox is to increase or reduce speed. As a result, torque output will be the inverse of the speed function. If the enclosed drive is a speed reducer (speed output is less than speed input), the torque output will increase; if the drive increases speed, the torque output will decrease.
Why does a car need a gearbox?
Gears are required to keep the engine at rotational speeds where it creates a desirable amount of power across a wide range of road speeds. Generally, the faster an engine turns, the more fuel it consumes, and the more power it makes. Engines are also only capable of rotating to a maximum speed (redline).
Is the gearbox part of the transmission?
The gear box is the chief component of the transmission system. The gearboxes are different for manual and automatic transmissions. Manual transmissions usually have five or six gears in the gearboxes. When the driver presses the clutch down, the sliding gear gets engaged with the appropriate gear.
