Drive chain意思

"Drive chain" is a term commonly used in the context of bicycles, motorcycles, and other vehicles that use a chain to transmit power from the engine or pedals to the wheels. The drive chain refers to the series of linked metal plates or links that rotate the rear wheel and propel the vehicle forward.

In bicycles, the drive chain connects the crankset (pedals) to the rear cassette or freewheel, which is mounted on the rear wheel. When the rider pedals, the chain drives the rear wheel, providing the necessary force to move the bike.

In motorcycles and other motorized vehicles, the drive chain connects the engine's output shaft (usually through a sprocket or gear) to the rear wheel, allowing the engine's power to turn the wheel and move the vehicle.

The drive chain is an essential component in these types of vehicles, as it is responsible for transferring the power from the source (human pedaling or the engine) to the wheels, making it a critical part of the drivetrain.
