Driving gear refers to the components in a vehicle's transmission system that transfer power from the engine to the wheels. This system includes various gears, such as the gearbox, which allows the driver to change speeds and control the vehicle's acceleration. Proper functioning of the driving gear is essential for smooth driving and efficient fuel consumption. In addition to the gearbox, driving gear also encompasses other elements like the clutch and differential. The clutch enables the driver to engage or disengage the engine from the wheels, while the differential allows for smooth turning by distributing power to the wheels at different speeds. Together, these components ensure optimal vehicle performance.
