A multi-speed gearbox is a mechanical system that allows a vehicle or machine to operate at different speeds and torque outputs by selecting from multiple gear ratios. It is commonly used in vehicles, machinery, and industrial applications where varying speed and power are needed.
When the gearbox shifts to a lower gear, the speed decreases, but the torque (power) increases. This is useful for starting from a stop or climbing hills.
When the gearbox shifts to a higher gear, the speed increases, but the torque decreases. Higher gears are used for cruising at higher speeds.
Gears: Different sized gears that mesh with each other to change the speed and torque.
Input Shaft: Receives power from the engine or motor.
Output Shaft: Transmits power to the drive system.
Synchronizers (in manual gearboxes): Help match the speed of the gears for smooth shifting.
Clutch: Engages and disengages the gearbox from the engine
Manual Gearbox: The driver manually shifts gears using a clutch pedal and gear stick.
Automatic Gearbox: Shifts gears automatically based on speed, load, and other parameters.
Semi-Automatic Gearbox: A hybrid system where gear changes are automated but can be controlled manually by the driver.
Dual-Clutch Gearbox (DCT): Utilizes two separate clutches for faster and more efficient shifting.
Automobiles: Passenger cars, trucks, and motorcycles.
Heavy Machinery: Excavators, bulldozers, and agricultural equipment.
Industrial Machines: Conveyor systems, compressors, and turbines.
