A drive system refers to the components that transmit power from a vehicle's engine to its wheels, enabling movement. This system can include various elements such as the transmission, differential, and axles. Different types of drive systems, like front-wheel drive or all-wheel drive, determine how power is distributed to the wheels. In addition to vehicles, drive systems are also found in machinery and equipment, where they help convert energy into motion. These systems can be powered by various sources, including electric motors or internal combustion engines, depending on the application and design requirements.
